Front passenger 's exterior mirror tilt
function*
To help you see the curb when backing into a
parking space, the surface of the mirror tilts
slightly. For this to happen, the knob must be in the position for the front passenger's exterior
mirror .
You can adjust the tilted mirror surface by turn­ ing the knob in the desired direction. When you
move out of reverse and into another gear, the
new mirror position is stored and assigned to the
key you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph
(15 km/h) or turn the ignition off .
A WARNING
Curved mirror surfaces (for example convex)
enlarge the field of v is ion. However, they
make objects in the mirror appear smaller
and farther away . You may estimate incor­
rectly when you use these mirrors to gauge
your distance from the vehicles behind you when changing lanes, which increases the risk
of an accident .
(D Note
-Applies to vehicles with power fo lding exte­
r ior mirrors : if the mirror hous ing was
moved by outside forces (such as an impact
when maneuvering), you must use the pow­ er folding function to fold the mirror all the
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous­
ing must not be
moved back into place by
hand because this would impair the func­
tion of the mirror mechanism.
- Applies to veh icles without power folding
exterior mirrors : if the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must
move it back
in place by hand.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors .
Never fold power fo lding exterior mirrors*
