injury.
iWhen you switch on the ignition, the in-
dicator and warning lamps (except high
beam headlamp indicator lamp and
turn signal indicator lamps unless acti-
vated) in the instrument cluster come

44 Getting startedAdjusting
Mirrors
Adjust the interior and exterior rear view
mirrors before driving so that you have a
good view of the road and traffic condi-
tions.Interior rear view mirror

Manually adjust the interior rear view
mirror.
For more information, see “Rear view mir-
rors” (
page 177).
Exterior rear view mirrors
iIf the current position for the steering
wheel is in the uppermost tilt position,
the steering wheel will no longer be
able to move upward when the
easy-entry/exit feature is activated.
The adjustment procedure is briefly in-
terrupted when the engine is started.Warning!
G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All steering wheel adjustment must be
completed before setting the vehicle in mo-
tion. Driving off with the steering wheel still
adjusting could cause the driver to lose con-
trol of the vehicle.
Warning!
G
In case of an accident, liquid electrolyte may
escape the mirror housing if the mirror glass
breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.
Warning!
G
Exercise care when using the passenger
side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.

iHow long the system will provide heat-
ing depends on the coolant tempera-
