Front passenger's exterior mirror tilt
function*
To help you see the curb when back ing 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 (aspheric or convex*)
enlarge the field of vision. 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
- If the mirror housing was moved by outs ide
forces (such as an impact when maneuver­
in g), you must use the power folding func­
tion to fold the mirror all the way out. The
mirror housing must not be moved back in-
to place by hand because this would impair
the function of the m irror mechanism.
-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.
48
Never fold power fold ing exterior mirrors by
hand . Only fold them in and out using the
power controls.

-If the power adjusting function malfunc­
tions, the glass in both mirrors can be ad­
justed by pressing on the edge of it by hand.

eyes and respiratory system. If there is con­
tact with the fluid, flush immediately with
p lenty of water . Consult a physician if neces­
sary.

-Repeated or long-term exposure to electro­
lyte fluid can lead to irritation of the air­
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi­
cle or, if this is not possible, open all of the
doors and w indows as wide as possible.
-If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount of
