Outside Automatic Dimming Mirror with Curb View Assist If your vehicle has this feature, the driver's and/or passenger's outside mirror will adjust to a preset tilt position while the vehicle is in REVERSE (R) gear. Curb view assist may be useful when you are parallel parking. The mirror(s) will return to normal position when the vehicle is shifted out of REVERSE (R) gear. Automatic mirror movement in either direction will follow a short delay. To first activate this feature, perform the following steps: 1. Press the Personalization button, located on the steering wheel, until "Tilt Mirror in REVERSE (R)" is displayed on the DIC display. 2. Press the Select button once to select the passenger's side mirror, twice for the driver's side mirror and three times for both mirrors. Then press the Personalization button repeatedly until the display goes blank. 3. With the engine running, engage the parking brake, press the brake pedal and place the vehicle in REVERSE (R) gear. 4. Adjust the passenger's side and then the driver's side outside mirrors to the desired tilt positions. These positions will be stored into memory once the vehicle is shifted out of REVERSE (R). When the vehicle is placed in PARK (P) or in any forward gear, the mirror(s) will return to normal driving position, following a short delay. To change the tilt position, adjust the mirror while the vehicle is in REVERSE (R) gear with the engine running, the parking brake engaged and the brake pedal pressed. The new position will be saved into memory once the vehicle is shifted out of REVERSE (R). 2-39
