ability to react to excessively high tempera-
tures may be affected or they may even suffer burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.

Switching on/off Seat ventilation is only available for the front
seats.
The three blue indicator lamps in the buttons
indicate the ventilation level you have selec-
ted.
X Make sure that the SmartKey is in posi-

i If you open the side windows and the slid-
ing sunroof using the SmartKey
(Y page 78), the driver's seat ventilation
automatically switches to the highest level.
X To switch off: press button:repeatedly
until all the indicator lamps go out.
i If the battery voltage is too low, the seat
ventilation may switch off. Problems with the seat ventilation If one or all of the indicator lamps in the seat
ventilation button are flashing, the seat ven-
tilation has switched off automatically. The
vehicle's electrical system voltage is too low
because too many electrical consumers are
switched on.

not need, such as the rear window
defroster or interior lighting.
Once the battery is sufficiently charged, the seat ventilation will switch back on auto-
matically. Steering wheel

ture
Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel and the driver's seat, you
and other vehicle occupants – particularly
children – could become trapped. There is a
risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the seat and
the steering wheel.
If somebody becomes trapped:
R press one of the memory function position
buttons, or
R press one of the memory function memory
buttons, or
R move the switch for steering wheel adjust-
ment in the opposite direction to that in
which the steering wheel is moving
The adjustment process is stopped. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off. !
Do not activate the EASY-ENTRY/EXIT
feature, if the seat backrest is reclined too
far backwards. This can damage the front
or rear seats. You must first move the back- rest to a vertical position.
The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board com-

Exterior mirrors
Adjusting the exterior mirrors G
WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. X
Make sure that the SmartKey is in position
1 or 2in the ignition lock (Y page 133).
X Press button :to select the left-hand
exterior mirror.
or
X Press button ;to select the right-hand
exterior mirror.
X Press button =up, down, or to the left or
right until you have adjusted the exterior
mirror to the correct position. You should
have a good overview of traffic conditions.
i The convex exterior mirrors provide a
larger field of vision.
i The exterior mirrors are heated automat-
ically if the rear window defroster is
switched on and the outside temperature is
low. Folding the exterior mirrors in/out elec-
trically X
Make sure that the SmartKey is in position
1 or 2in the ignition lock (Y page 133).
X Briefly press button :.
Both exterior mirrors fold in or out.
i Make sure that the exterior mirrors are
always folded out fully while driving. They
could otherwise vibrate.
i If you are driving faster than 9 mph
(15 km/ h), you can no longer fold in the
exterior mirrors.
Setting the exterior mirrors If the battery has been disconnected or com-
pletely discharged, the exterior mirrors must
be reset. The exterior mirrors will otherwise
not fold in when you select the "Fold in mir-
rors when locking" function in the on-board
computer (Y page 209).

The cornering lamp may remain lit for a short
time, but is automatically switched off after

ged up on the inside
The headlamps and the indicator lamps in the exterior mirrors may fog up on the inside if
there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:
X Have the headlamps checked at a qualified
specialist workshop. Interior lighting

ªrear window
defroster button flashes, the on-board volt-
age is too low. The rear window defroster has
deactivated prematurely or cannot be activa-
ted.

heat function
The "residual heat" function is only available
in Canada.
It is possible to make use of the residual heat
of the engine to continue heating the station- ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
