— When you drive forward at speeds faster than 9
mph (15 km/h).

the front passenger exterior mirror

Z\ WARNING
Curved mirror surfaces (for example convex)
enlarge the field of vision. However, they
make objects in the mirror appear smaller and
farther away. When using these mirrors to es-
timate your distance to vehicles behind you
when changing lanes, you could estimate in-
correctly, which increases the risk of an acci-
dent.

@) Note
— Applies to: vehicles with power folding exte-
rior mirrors: If the mirror housing 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
56
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 could impair the function
of the mirror mechanism.
— Applies to: vehicles 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 folding exterior mirrors*
by hand. Only fold them in and out using
the power controls.
@) Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.

— Electrolyte fluid can leak out from broken
mirror glass. This liquid can irritate the skin,
eyes and respiratory system. If there is con-
tact with the fluid, flush immediately with
plenty of water. Consult a physician if neces-
sary.

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 windows as wide as possible.
