2019 GMC Sierra 1500 Owners Manual - Exterior Mirrors

Exterior Mirrors

The passenger side mirror is convex shaped. A convex mirror's surface is curved so more can be seen from the driver seat.

If equipped, adjust manual mirrors by moving the mirror up and down or left to right to see a little of the side of the vehicle and to have a clear view behind the vehicle.

Using hood-mounted air deflectors and add-on convex mirror attachments could decrease mirror performance.

Select } or | for the driver or passenger side mirror. The switch will illuminate.

Press the arrows on the control pad to move the mirror up, down, right, or left.

Adjust each outside mirror so that a little of the vehicle and the area behind it can be seen.

The mirrors may be equipped with a memory function that works with the memory seats. See Memory Seats 0 74.

There may be cargo lamps on the bottom of the mirrors. See Exterior Cargo Lamps 0 184.

If equipped, push the mirror toward the vehicle to fold. Push the mirror outward to return to its original position.

If equipped, the driver outside mirror automatically adjusts for the glare of the headlamps from behind. This feature comes on when the vehicle is started.

If equipped, there is a small convex mirror built into the upper and outer corner of the driver outside mirror. It can show objects that may be in the vehicle's blind zone.

Actual Mirror View

When the approaching vehicle is a long distance away, the image in the main mirror is small and near the inboard edge of the mirror.

As the vehicle gets closer, the image in the main mirror gets larger and moves outboard.

As the vehicle enters the blind zone, the image transitions from the main mirror to the blind spot mirror.

When the vehicle is in the blind zone, the image only appears in the blind spot mirror.

Set the main mirror so that the side of the vehicle can just be seen and the blind spot mirror has an unobstructed view.

When checking for traffic or before changing a lane, look at the main driver/passenger side mirror to observe traffic in the adjacent lane, behind your vehicle. Check the blind spot

mirror for a vehicle in the blind zone. Then, glance over your shoulder to double check before moving slowly into the adjacent lane.

If equipped with memory seats, the passenger and/or driver mirror tilts to a preselected position when the vehicle is in R (Reverse). This allows the curb to be seen when parallel parking.

The mirror(s) return to the original position when:

The vehicle is shifted out of R (Reverse), or remains in R (Reverse) for about

30 seconds.

The ignition is turned off.

The vehicle is driven in

R (Reverse) above a set speed.

To turn this feature on or off, see

Vehicle Personalization 0 170.
