Adjusting
Easy-entry/exit feature
This feature allows for easier entry into and
exit from the vehicle. When entering and
exiting the vehicle, the steering wheel is in
its uppermost position.
The easy-entry/exit feature can be activat-
ed or deactivated in the
Convenience sub-
menu of the control system (
page 148).With the easy-entry/exit feature activated,
the steering wheel will return to its last set
position when you:

close the driver’s door with the ignition
switched on,
or

insert the SmartKey into the starter
switch with the driver’s door closed. 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 position0
or1.
Warning!G
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To cancel steering wheel movement, do one
of the following:

Move steering column stalk
(
page 38).

Press memory position switch
(
page 112).
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
i
The last set steering wheel position is
stored when

the ignition is switched off

the position is stored in memory
(
page 112)

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 in-
terrupted when the engine is started.

Warning!G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz
Center.Warning!G
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 garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.

function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.
Parking brake
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave

Driving
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
!
If you hear a warning signal and the
message
Release parking brake ap-
pears in the multifunction display when
driving off, you have forgotten to re-
lease the parking brake.
!
Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
i
