: sts speedometer

07-13-09, 08:38 PM
hello people,

this is the first time for me in this forum and i want to buy a used cadillac srx or sts
but the fact is i got used to see the speedometer in km/h not mph

so could i change this by a button or something ?

what is really change:
1- the number itself becuase i have seen different types of numbers for km/h and mph

2- or the change occurs on the movments of arrow itself and the numbers still the same

if anyone can show this difference in pictures would be greatful.

finally i want to make sure that this applies on srx and sts

and from which year this applies on like from 2005 until now or what?

thanks in advance

I don't know about other Caddies but my 05 STS can change from one speedometer mode completely to the other.

You can change from english to metric with the E/M switch. Everything but the tach and radio change. In the case of the speedo, the needle moves to a higher position when in k/m, and HVAC temps read in C. The change also effects the DIC readings.
