Driving and Operating When Tow/Haul is activated the Tow/Haul symbol will come on the instrument panel cluster. See "Tow/ Haul Mode" under Driving Characteristics and Towing Tips on page 9‑44 for more information. 9-25 Drive Systems All-Wheel Drive With this feature, engine power is always sent to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions. When using a compact spare tire on an AWD vehicle, the system automatically detects the compact spare and disables AWD. To restore AWD operation and prevent excessive wear on system, replace the compact spare with a full-size tire as soon as possible. See Compact Spare Tire on page 10‑77 for more information. Brakes Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started and the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal. Automatic Engine Grade Braking Automatic Engine Grade Braking assists when driving on a downhill grade. It maintains vehicle speed by automatically implementing a shift schedule that uses the engine and the transmission to slow the vehicle. The system will automatically command downshifts to reduce vehicle speed, until the brake pedal is no longer being pressed. While in the Electronic Range Select (ERS) mode, grade braking is deactivated, allowing the driver to select a range and limiting the highest gear available. Grade braking is available for normal driving and in Tow/Haul mode. See Automatic Transmission on page 9‑22. If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5‑19.
