Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

in the main mirror is small and
near the inboard edge of the
mirror.
2. As the vehicle gets closer, the image in the main mirror gets
larger and moves outboard.
3. As the vehicle enters the blind zone, the image transitions from
the main mirror to the blind spot
mirror.
4. When the vehicle is in the blind zone, the image only appears in
the blind spot mirror.
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.
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.

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.
