Problems with the steering wheel heating
Problem
Possible causes/consequences and
M
MSolutions The steering wheel
heating has switched
off prematurely or can-
not be switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting. EASY-ENTRY/EXIT feature
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 there is a risk of becoming trapped by
R the steering wheel: move the steering
wheel adjustment lever.

ment.

when unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. 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.
The EASY-ENTRY/EXIT feature makes getting in and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature using COMAND (see theseparate operating instructions).

Crash-responsive EASY-EXIT feature If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened or the SmartKey is removed from the ignition lock. This makes it easier to exit the
vehicle and rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY fea-
ture is activated in COMAND (see the sepa-
rate operating instructions). Mirrors
Rear-view mirror

Important safety notes G
WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. 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. 140
