9-26 . Driving and Operating The gas pedal will be less sensitive. The vehicle's computers will more aggressively shut off fuel to the engine under deceleration. The engine operates at lower rpm's in fuel economy mode, which can increase noise and vibration. This is normal. Drive Systems All-Wheel Drive Vehicles with this feature transfer torque as required to the rear wheels. It is fully automatic, and adjusts itself as needed for road conditions. AWD system performance will be automatically reduced when you use the compact spare. To restore full AWD operation and prevent excessive wear on the system, replace the compact spare with a full-size tire as soon as possible. See Compact Spare Tire on page 10-78. Brakes Antilock Brake System (ABS) This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid. When 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. . . If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-19.
