Driving If the steering wanders or pulls, check for: an improperly inflated tire uneven tire wear loose or worn suspension components loose or worn steering components improper steering alignment AUTOMATIC TRANSMISSION OPERATION Brake-shift interlock This vehicle is equipped with a brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) when the ignition is in the on position unless the brake pedal is applied. If you cannot move the gearshift lever out of P (Park) when the ignition is on and the brake pedal applied, it is possible that a fuse has blown or the vehicle's brake lamps are not operating properly. Refer to Fuses and relays in the Roadside Emergencies chapter. If the fuse is not blown and the brakelamps are working properly, refer to your authorized dealer. WARNING: Do not drive your vehicle until you verify that the brakelamps are working. WARNING: Always set the parking brake fully and make sure the gearshift is latched in P (Park). Switch the ignition to off, and remove the key whenever you leave your vehicle. WARNING: If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. Understanding the gearshift positions of the 6-speed automatic transmission Your vehicle has been designed to improve fuel economy by reducing fuel usage while coasting or decelerating. When you take your foot off the accelerator pedal and the vehicle begins to slow down the torque converter clutch locks up and aggressively shuts off fuel flow to the engine while decelerating. This fuel economy benefit may be perceived as a light to medium braking sensation when removing your foot from the accelerator pedal. 230
