Steering wheel EASY-ENTRY/EXIT fea-
ture
Important safety notes
GWARNING
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:
Rpress one of the memory function position
buttons, or
Rpress one of the memory function memory
buttons, or
Rmove 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.
GWARNING
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 fea-
ture, if the seat backrest is reclined too far
backwards. This can damage the front or rear
seats. You must first move the backrest 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 computer

Adjusting the exterior mirrors
GWARNING
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.
XMake sure that the SmartKey is in position 1
or 2in the ignition lock (Ypage 105).
XPress button :to select the left-hand exte-
rior mirror

cally if the rear window defroster is switched
on and the outside temperature is low.

trically
XMake sure that the SmartKey is in position 1

(15 km/h), you can no longer fold in the exte-
rior mirrors.
Resetting 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 mirrors when
locking" function in the on-board computer

There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release

!Warm up the engine quickly. Do not use the
engine's full performance until it has reached
operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Avoid high engine speeds when the engine
is cold. The engine's service life could other-
wise be significantly shortened. Do not use
the engine's full performance until it has
reached operating temperature.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.
