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
slight ly. 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 (convex) enlarge the
f ield of vision. However, they make objects in
the m irror appear smaller and farther away.
You may estimate incorrectly 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 th e mirror housing was moved by outs ide
fo rces (such as an impact when maneuver ­
i ng), you must use the power fold ing funct ion
to fold the mirror a ll the way out . The mirror
housing must not be moved back into place
by hand because th is would impair the func­
tion of the mirror mechanism.
(D Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.

A WARNING
Electrolyte fluid can leak from automatic dim­
m ing mirrors if the glass is broken. Electro­
lyte fluid can irritate skin, eyes and airways.
- Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the a ir ­
ways, especially in people with asthma or
other resp irato ry conditions. Take deep
breaths immed iate ly after leaving the vehi­
cle or, if this is not possible, open all of the
doors and windows as wide as possible .
-If electrolyte f lu id ente rs the eyes, flush
them thoroughly with a large amount of
clean water for at least 15 minutes and then
seek medical attention.
- If electrolyte f luid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thoroughly before wearing again .
- If the fluid was swallowed and the person is conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by med ical pro-
42
fessionals . Seek medical attention immedi­
ately .
(D Note
If the glass on an automatic dimming mirror
breaks, electro lyte can leak out . This liquid
damages plastic surfaces. Remove the liquid
as quickly as possible, for example us ing a
wet sponge.
(D Tips
- If the light reaching the rearview mirror is
obstructed, the automatic dimming mirror
will not function correctly,
- The automatic dimming mirrors do not dim
