Adjusting
With the easy-entry/exit feature activated,
the steering wheel tilts upwards when you
remove the SmartKey from the starter
switch
or
open the driver’s door with the
SmartKey in starter switch position 0
or 1 or the KEYLESS-GO* start/stop
button in position 1 (
page 40)
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.
i
If 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 interrupted
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 liquid state and by apply-
ing plenty of water.

Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.
i
You can also use the “touch-start” function.
Turn the SmartKey to position3 and release it
again immediately. The engine then starts auto-
matically.
