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.

Reverse Tilt Mirrors

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 on
page 5-46.
