Outside Manual Mirrors If the vehicle has the manual outside mirrors, adjust each outside mirror so that a little of the vehicle and the area behind it can be seen while sitting in a comfortable, driving position. Both mirrors can be manually folded inward by pulling them towards the vehicle. Push the mirrors away from the vehicle, to the normal position, before driving. Turn the knob counterclockwise or clockwise to adjust the driver's or passenger's mirror so that you can see a little of the side of your vehicle. After adjusting the position of the mirrors, turn the knob to the center position so that the mirrors cannot move. If the travel position in any direction of the mirror is reached, it will enter a ratcheting mode. This action is harmless. It is a warning that the mirror can go no further. To stop this action, back the mirror up by moving the knob in the opposite direction. Outside Power Mirrors The vehicle may have this feature. The control is located on the driver's door. Outside Curb View Assist Mirror If the vehicle has this feature, the 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 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. You may be able to turn this feature on or off through the Driver Information Center (DIC).
