The all-new 2010 Cadillac SRX midsize crossover represents a significant departure from its rear-drive predecessor as a more integrated and highly styled entry. It’s based on General Motors’ all-new global midsize front-drive crossover architecture (also called Theta-Epsilon). The new SRX has a dramatic presence — from its prominent shield grille and large, center-positioned wreath and crest to the vertically oriented, contemporary “tailfin” taillamps that incorporate more than 40 LEDs per lamp.

Global-A Serial Data Electrical
The SRX uses the GM Global-A Serial Data Electrical Architecture – a high-and low-speed data network that connects system modules. The Body Control Module (BCM) is the heart of the electrical system, acting as a gateway between the high-speed and low-speed data buses.

VIN Structure Change for 2010
Several changes are being made to the numbering structure for VINs (Vehicle Identification Numbers) for both trucks and cars, beginning with the 2010 model year. See the accompanying illustrations.
The VIN structure was instituted by all vehicle makers in 1981 in compliance with government regulatory requirements. The VIN contains standardized data required by government and insurance agencies.

TRUCKS and MPVs
For LD trucks and multi-purpose vehicles (MPVs), beginning with 2010, there is a new requirement for the VIN to identify the restraint system devices and locations. Position 7 will be used for this purpose (it formerly indicated Body Type).
TIP: Previously, position 7 Restraint System was not common between trucks and cars. Now, it is.
Position 4 previously indicated GVWR/Brake Systems and now indicates GVWR/Brake Systems and Body Style.
Positions 4, 5 and 6 are now alpha-numeric and position 7 is alpha only. This increases the number of systems that can be described with a single character. See the accompanying illustrations on page 4.
