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. (Fig. 1)

(Fig. 1)
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.
TIP: You will use the MDI with GDS software and a laptop PC in place of the Tech 2 for diagnosis.
Passive Entry and Passive Start Systems
The optional Passive Entry System enables operation of the doors, ignition and liftgate without removing the transmitter from a pocket or purse. With the transmitter within 3 feet (1m) of the doors, the driver's door or all doors will unlock automatically when any door handle is pulled.
All doors will lock automatically when the ignition is off, the transmitter is removed from the vehicle, all doors are closed, and the lock sensor on a front door handle is pressed. (Fig. 2)

(Fig. 2)
TIP: From inside the vehicle, when the door is locked, it is necessary to pull the inside handle TWICE - first to unlock, second to release the door latch.
The standard Passive Start System features a START/STOP button on the instrument panel to start the engine. The vehicle must be in Park or Neutral with the brake pedal depressed. When the engine starts, the indicator on the button will illuminate green. (Fig. 3)
(Fig. 3)
TIP: If the transmitter battery is weak, insert the transmitter into the slot above the Accessory Power Outlet in the center console lower storage area to enable the engine to start.
To turn off the engine, shift to Park and press the START/STOP button. Power to the audio system, windows and sunroof will be active for 10 minutes or until a front door is opened.
With the engine off and the brake pedal NOT depressed:
- Press the START/STOP button to place the ignition system in the Accessory position. The yellow indicator will illuminate.
- Press the button again to place the ignition in the On position. The instrument cluster and the green indicator will illuminate.
- Press the button once more to return to the Off position.
The systems work via six ferrite stick antennas located in each of the front door handles; the center console rear of the shifter; underneath the instrument panel; in the cargo area; and within the rear bumper of the vehicle. The antennas determine whether the transmitter is in or out of the vehicle. Upon pulling any exterior door handle, or pressing the liftgate access button, the closest antenna within the vehicle wirelessly interacts with the transmitter, and within 260 milliseconds, authorizes the identity of the driver and allows vehicle entry.
Powertrains
There are two powertrain combinations available on the SRX.
The base 3.0L DOHC DI VVT V6 engine (RPO LF1) (Fig. 4) produces 265 horsepower (198 kW) and 223 lb.-ft. (302 Nm) of torque and is mated to the 6T70 Hydra-Matic six-speed automatic transmission.

(Fig. 4)
The 3.0L direct injection V-6 is a smaller displacement version of the 3.6L, direct injection engine featured in the CTS sedan. The DI VVT V6 engine employs four-cam phasing to change the timing of valve operation as RPM and engine load vary for a linear delivery of torque, with near-peak levels over a broad RPM range while reducing emissions.The 2.8L DOHC VVT turbo V6 engine (RPO LAU) with the AF40 Aisin-Warner six-speed automatic transmission is optional and will be available in late 2009. (Fig. 5)

(Fig. 5)
The turbo V6 engine generates 300 horsepower (224 kW) and 295 lb.-ft. (400 Nm) of torque.
Driver's also can use the Fuel Economy (Eco) mode on turbocharged V6 models, activated by pressing the ECO button next to the shift lever, to help improve the vehicle's fuel economy. When active, the Eco mode changes the transmission shift points and makes several other fuel saving adjustments. This changes the vehicle's performance and results in a more conservative driving characteristic.
Towing Capacities
RPO V92 includes the following towing provisions on the SRX:
- Hitch
- Harness
- Rear fascia closeout
- Auxiliary transmission oil cooler
An SPO accessory trailer hitch package also is available that includes the same components as RPO V92.
The SRX's trailer towing maximums when properly equipped:
- 3.0L V6 - 2500 lbs./1136 kg (without auxiliary transmission oil cooler)
- 3.0L V6 - 3500 lbs./1590 kg (with towing package)
- 2.8L V6 - 3500 lbs./1590 kg
All-Wheel-Drive System
The electronically controlled, on-demand all-wheel-drive system provides power to the front wheels during normal driving on dry road surfaces. If the front wheels slip, power is automatically delivered to the rear wheels as well.
The system includes a power takeoff unit attached to the transaxle, a three piece propeller shaft, a compact Rear Drive Control Module (RDCM), and an Electronic Limited Slip Differential (ELSD) system.
The limited slip differential clutch is a disc type that is electro-hydraulically controlled by the rear drive control module (RDCM) via a pressure control valve fitted on the differential clutch housing. The disc pack separately distributes the torque between the rear wheels. The disc pack is compressed by an operating piston that is controlled by the RDCM.
Tire Sealant and Compressor Kit
The SRX does not have a spare tire as standard equipment. The tire sealant and compressor kit can be used to temporarily seal small punctures in the tread area of a flat tire. The kit is located in the rear storage compartment of the cargo management system. Refer to the kit instructions for complete operating information.
Electronic Suspension Control
The ZF Sachs electronic suspension control system (RPO F45), individually changes the damping force of each of the shock absorbers within milliseconds. Suspension characteristics can be changed at any time by activating the Sport mode or Tour mode through the gear shifter's position. The suspension control module evaluates various sensor inputs in order to separately control the damping forces of the shock absorbers.
Infotainment and Navigation
Thanks to the separation of "silver box" control modules from relating instrument panel-mounted control interfaces, the new SRX has a contemporary Integrated Center Stack (ICS) design, free of the stacking of radio/HVAC/display component boxes. (Fig. 6)

(Fig. 6)
The Navigation System incorporates a satellite-based enhanced HDD-based Navigation. A DVD is not required for the navigation database due to the 40 GB hard drive storage.
Through a USB jack located in the vehicle's center console, digital audio music files - such as MP3, WMA, M4A, and ACC files - can be downloaded to the hard drive for storage and playback.
TIP: The USB jack provides true iPod® capability, enabling recharging and control of the iPod. However, not all iPod devices are compatible, in which case it's necessary to use the AUX jack.
Front/Rear Park Assist
The system uses four bezel-less integrated sensors on the front and rear fascias to help avoid colliding with objects when parking the vehicle at speeds less than 5 mph (8 km/h).
Detected objects are indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to an object. A distance display in the instrument cluster also indicates when objects up to 4 feet (1.2m) in front of the vehicle are detected. There is no rear distance display on the headliner.
The system can be turned on/off by pressing the Parking Assist button next to the shift lever.
Power Liftgate
The power liftgate has a memory height feature. Its operation is similar to the power liftgate in the new 2010 Equinox (See June 2009 TechLink) and 2010 CTS sport wagon.
The power liftgate has three modes of operation. Mode selection is controlled by the interior mode switch on the driver's door. (Fig. 7)

(Fig. 7)
Off Mode (Disable) - Power is disabled. The liftgate will operate as a manual liftgate.
TIP: Manual effort is higher than with a standard non-power liftgate.
3/4 Mode (Programmable) - The liftgate powers open to a height programmed by the owner (to prevent the liftgate from hitting overhead obstructions or to make it easier to reach the liftgate when open).
Max Mode (Full Open) - The liftgate will power open to the full open height.
To program the memory height, manually open the liftgate to the desired height, and then press and hold the button on the liftgate adjacent to the latch until the taillamps flash and a beep sounds, which indicates that the setting is stored. Be sure to turn the power liftgate switch to the 3/4 Mode position to have the liftgate open to the programmed height.
Power Folding Mirrors
To fold or unfold the power mirrors, place the power mirrors selector switch in the middle position and then press the down arrow on the control switch.
TIP: The power mirrors should be folded before entering an automatic car wash. If the power mirrors are folded/unfolded manually, they will have to be reset. Otherwise, they may not function properly or may vibrate while driving. Follow the Owner Manual procedure for resetting the power mirrors.
Memory Seats
The memory seats function allows the driver to set the seat, power outside mirrors and adjustable pedals to a set position. The recall of these positions has changed from previous memory systems.
To recall the memory positions, the driver must press and hold button 1 or 2 until the memory position is reached. Releasing the button before the memory position is reached cancels the recall.
Sunroof
The optional sunroof adjusts automatically to different positions based on vehicle speed in order to reduce wind noise. At lower speeds, it opens or closes to the comfort (3/4 open) position. When the vehicle is travelling at higher speeds, it opens fully.
The sunroof switch has two detents. Pressing lightly to the first detent will vent the sunroof and depressing the switch fully will open the sunroof.
Cooled Glove Box
The SRX features an air conditioned glove box that can be used to store items at a cooler temperature. The air conditioning must be turned on for maximum cooling.
To turn the cool air flow on or off, move the slide control on the left-front side of the glove box across the small opening. (Fig. 8)

(Fig. 8)
Close the opening during cooler weather to keep cold air from entering the vehicle.
Adaptive Forward Lighting
The Adaptive Forward Lighting (AFL) system adjusts the headlamps in various driving situations. The headlamps pivot left or right in the direction of travel. While continuously traveling straight, headlamp range increases or decreases based on vehicle speed.
The AFL system will not operate at speeds less than 2 mph (3 km/h) or until after driving a short distance to calibrate the system. The exterior lamps control knob must be in the AUTO position.
