Using the Outside Mirror with
the Blind Spot Mirror
1. Set the main mirror so that theside of the vehicle can just be
seen and the blind spot mirror
has an unobstructed view.
2. 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.
Park Tilt Mirrors
If the vehicle has the memory
package, the outside mirrors have a
park tilt feature. This feature tilts the
outside mirrors to a preselected

The passenger and/or driver mirror
returns to its original position
when the vehicle is shifted out of
R (Reverse), or the ignition is turned
off or to OFF/LOCK.
This feature can be turned on or off
through the Driver Information
Center (DIC). See Vehicle
Personalization (With DIC Buttons)
on page 5‑46 for more information.
