With the last level Nav installed on SRX you can't see TV or DVD or you can't change GPS choices when driving
Ist ist really for safety reason ?
Because
When driving during the night in a very dark area, ALL THE LIGHTS are suddenly OFF , because the battery level is at low level, and close to die (2 years old !)

This is again, one of the american way of thinking : I think for you.
Supposing people are not clever enough to be allowed to use their own free will.

To be so obstinated for secure or safety reason, the result is more dangerous than if nothing was done.

All your base are belong to us.

I'd actually like to discuss this with you, but I'm assuming by your grammar and delightful jab at the "Typical American thinking" that English isn't your first language. I'll give it a shot anyway:

The dashboard lights and NAV screen dim when the headlights come on. If they're too dark for you, adjust the dimmer switch. The lights won't dim if the battery is low.

As far as the Nav inputs being disabled when moving, 95% of vehicles built are the same way- whether or not you're American, you should be looking at one thing only when driving: The road ahead of you.

For a better understanding, when i say ALL LIGHTS, it means HEADLIGHTS too were off, otherwise i would have not complained.

I am not sure I understand what you mean, but the "load shedding" capability of the vehicle DOES NOT INCLUDE turning off the headlights at night to conserve power.
If the battery needs to be replaced then by all means get it replaced.

If the headlights are turning off then have that diagnosed and repaired as soon as possible, it is not "normal".

I felt like in "2001 space odissey" where computer Carl tooks his own decision out of normal rules.

I agree with you, headlights off during a night travel when battery is low is not normal. But it happend, and put all my familly in danger.

By the way, bought in 2005 this SRX with NAV option @ $3800
GPS is at a 2004 level.
GOT NO GPS UPDATE SINCE THAT TIME IN EUROPE. 3 Years and half without update. If someone know why tks to tell.

Then I would say to have your vehicle checked at the earliest available opportunity.
It is not designed to do that, something is broken.

Disk comes out in August of each year. So, if the vehicle was obtained or produced before August 2005, there is no way it could come with the 2005 disk. In US, we get two free updates. They don't just send them to you though. You need to request them. I don't know about your area. Try to get online to the GMDISK website for more info. And stop being so angry. Its not good for you. :thumbsup:

Headlights:
My SRX just come back from control and of course nothing found against this problem.

And now a new one with automatic headlight :
Automatic timing is dramaticaly too long.
When I enter a dark area like a tunnel it takes 45 seconds for the headlights to switch on.
On Highway small tunnels lights are off in the tunnel but switch on when i leave the tunnel ! and of course any item in the NAV to allow to change this parameter
(3 seconds on my Wife's Mini)

GPS : Cadillac Europe in Netherland has been contacted and they confirm NO GPS UPDATE for Europe since 2004 !!!!!!!

fully disapointed !

Seems like a low battery could create wacky things with the electronics in the vehicle -- many probably unintended. Couldn't it even be low enough to be unable to power headlights?

I've never even heard of "load shedding". Is there something on the vehicle that recognizes a low battery and turns things off? That sounds pretty dangerous -- is there a list of what it can turn off? ewill3rd, can you provide more info?

Battery problems can cause some weird things to happen. A year or so ago my '94 MARK VIII interior lights started staying on. I would have to pull a fuse that also was the fuse for the power seat and as I recall the door locks. Thought sure it was the relay that I could hear clicking in the trunk. Found a relay on the Internet and before I got it installed I searched the Lincoln Mark forum. Found info regarding batteries that are about to die and the weird electrical problems one can have. The original battery was replaced and I still have the relay. No doubt the electronics on newer cars may be more prone to electrical glitches. Ah yes the model "A" Ford, gravity feed fuel etc etc etc. Life was simple.

On the turn signal lever there should be a switch, that allows you to turn on the headlights in considerably less than 45 seconds.
That particular feature is designed that way for a reason, and that is why there is a switch on the turn signal lever. I don't mean to seem rude, but it spells out clearly how this feature works in the owner's manual, it is obvious that your expectation in this regard does not match the actual operation of the vehicle. No one can fix that.

How many times has your nav system gotten you lost since 2004?
Are your maps really that unreliable? If it gets you where you need to go why would it be a problem if the disc hadn't been updated since 1956?

Maybe you should look at buying one of those nice European cars everyone is always bragging about?

Sorry to hear your dealer couldn't figure out what was wrong that caused your headlights to shut off. Maybe they didn't have enough information on the failure condition to duplicate the problem and discover what happened?
At any rate, I am sure they tried their best.

Here is some information on the load shedding system that is integrated into the electronics on this vehicle.
Please notice the engineers don't turn the headlights off at all in this process, but it does deactivate a lot of features in the process.

Load Shed System Description and Operation
Electrical Power Management
Electrical power management (EPM) is used to monitor and control the charging system and alert the driver of possible problems within the charging system. The EPM system makes the most efficient use of the generator output, improves the battery state-of-charge (SOC), refer to Battery Description and Operation , extends battery life, and manages system electrical loads. EPM has also been know as "load management" or "load-shed" in the past.

EPM performs the following 3 functions:

Monitors battery voltage and estimates battery SOC
Takes corrective actions by boosting idle speed, reducing system electrical loads, and/or adjusting the generator regulated voltage control (RVC).
Perform diagnostics and informs the driver of charging system malfunctions
The EPM algorithm is run any time the dash integration module (DIM) is awake, which includes engine running, key on, accessory mode, and retained accessory power (RAP). During this time the DIM continuously estimates the battery SOC based on battery voltage, estimated net amp hours, refer to Battery Description and Operation , battery capacity, initial SOC, and estimated battery temperature. Estimated battery temperature is a calculation based on key off time, engine run time, and the temperature reading provided by the engine control modules (ECM) air intake temperature or HVACs outside air temperature.

When the EPM algorithm is running, the DIM calculates the net charge rate on the electrical system by making constant voltage measurements. It uses the measurements to calculate the charge rate in amp/hours. If the DIM detects a negative charge rate, equal to a discharge from the battery, EPM can request up to 3 levels of idle boost from the ECM, when the vehicle is in park or neutral, as well as up to 2 levels of load shedding for a total of 5 levels of corrective action to maintain proper vehicle electrical system operation.

The DIM sends a serial data request to the PCM/ECM to increase the idle speed. The PCM/ECM then adjusts the idle speed by using a special program and idle speed ramp calculations in order to prevent driveability and safety concerns. The idle speed boost and cancel function will vary from vehicle to vehicle and from one moment to another on the same vehicle. This happens because the PCM/ECM responds to changes in the inputs from the sensors used to control the powertrain. In order to maintain Idle quality the ECM may not enter idle boost for up to 120 seconds, unless there is a manual change in throttle position. There is no set time limit for the idle decrease when the criteria has been met to exit idle boost, unless there is a manual change in throttle position.


Important
The DIM also has responsibility for requesting up to 3 levels of idle boost from the ECM for the HVAC system based upon head pressure, vehicle speed, and engine running. EPM has priority over the HVAC system when requesting idle boost. However, idle boost will be maintained at the level the HVAC system requires, even though the exit criteria has been met for EPM.


Each EPM function, either idle boost or load-shed, is discrete. No 2 functions are active at the same time. However, the set flags may be set at the same time. Idle boost is activated in incremental steps, idle boost 1 must be active before idle boost 2 can be active. The criteria used by the DIM to regulate EPM are outlined below:

Function
Battery Temperature Calculation
Battery Voltage Calculation
Amp-hour Calculation

Clear Load Shed 2


During each load management function, the DIM checks the battery temperature, battery voltage and amp-hour calculations and determines if the DIM should implement a different power management function.

The highest loads on the electrical system are the resistance load of heating elements. The DIM controls the heating elements in the outside rear view mirrors, the rear window and the heated seats, either directly or by sending messages to any module controlling power to these devices.

The second highest load on the electrical system are the blowers used in the HVAC system. The DIM will send messages to the HVAC system controller that will result in reducing the blower operation on vehicles equipped with automatic HVAC systems.

Load-Shed
This vehicle uses the following load-shed actions:

Load Shed Level
Affected Systems
Action Taken

Load-Shed Level 0
No systems affected
Normal operation

Load-Shed Level 1
Heated Outside Rear View Mirrors, Heated Rear Window / Rear Window Defrost, Heated Seats
Cycled at 80% duty cycle, OFF for 4 of every 20 second cycle. Indicator and timer not affected.

Message Center, Instrument Cluster
No messages or indicators are displayed. Data (DPID) indicating that the Load-Shed 1 was entered is stored and may be accessed with a scan tool. DPID will reset after 40 ignition switch cycles with no repeated load-shed 1 action or with a battery disconnection.

Load-Shed Level 2
Heated Outside Rear View Mirrors, Heated Rear Window / Rear Window Defrost, Heated Seats
Turned OFF. Indicator and timer are not affected. The indicators and timers are controlled by the RIM. The operator must turn ON system when load-shed level is exited. System will not respond to operator input until current load-shed level is exited. This system will respond to only one Load-Shed Level 2 command per ignition switch cycle.

Message Center, Instrument Cluster
"Battery Saver Action" message is displayed. Charge indicator is illuminated. Data (DPID) indicating that the Load-Shed Level 2 was entered is stored and may be accessed with a scan tool. DPID will reset after 40 ignition switch cycles with no repeated Load-Shed 2 actions or with a battery disconnection.

Thank you so much Ewill3rd for your help. Of course European owners manual and documentations are so light and Cadillac Services in Europe is so low, that this forum is this only way to be well informed.

GPS : yesterday it told me to turn on a forbiden road as this road became a one way only end of 2005.
It ignores of course, new higways build in south europe in 2005/2006 etc... etc...

Yes, on the turn signal lever there is a switch to reduce from 45s to 0, as it goes from automatic to manual.
But i drive more than 62000 miles a year, and features like this one are important to me.
Europe : Its not like in the States = when we go from a country to another rules, regulations, pannel languages are completly differents, and for safety reason automatism should help to keep attention free on the road.

Can you provide more information on how to get the two free updates? Your post is the first that I have heard anything about free upgrades.

SRX, I think I came off too harsh on that last post.
Sorry for that.
I understand your concerns, but as I said there is no real way to modify the way the car is designed. It is kind of the lesser of two evils, obviously you don't want the system to change the lights immediately on low light conditions, driving down a wooded highway or in the city with lots of tall buildings would make your car look like a disco tech with the lights flashing on and off.

I see your point on the nav system, my guess is that GM doesn't have a huge market share over there so they don't invest a lot of time and energy on map updates like they do here.
There are still glitches in the software for this part of the world too, I have a lot of complaints about systems telling people to turn the wrong way or pass something and then turn around. Sadly there is nothing I can do except tell them to hope it is fixed in the next software release.
Keeping the US maps up to date and fixing glitches keeps them pretty busy I am sure. Do you have a European customer care number for General Motors or Cadillac over there? Maybe you could bring this to their attention.
I have a friend in the assembly plant that I might be able to ask about Euoropean software updates, maybe he could at least tell me if anyone is looking into it or not.

Don,

Go to www.gmnavdisc.com and I think there are instructions on there for getting your two free updates.
I think this only applies to 2006 and 2007. I am told that for 2008 this program will no longer be offered.

Hi Ewill3rd,

GM is making a huge job for Cadillac/Corvette cars to be sold at a maximum level in Europe.

www.gmnavdisc.com is done for US/Canada not for Europe. Car sold in Europe cars have a VIN not recognised by their web site.

I will let them to do it until they understand what is a customer respect, because $3800 a NAV system without update is not acceptable.

Sorry for boring you with these pbs, I won't keep on to do it, as my order for an Audi Q7 has just been confirmed.
