keep hands and fingers away from the door or
trunk opening when closing a door or the
trunk lid. Be especially careful when small
children are around.
In case of danger, pull the inside or outside
door handle, or pull the trunk lid handle.
To prevent personal injury, never actuate the
closing assist mechanism by tampering with
the door or trunk lid latch.

Safety notes
GWarning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts
GWarning!
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
GWarning!
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R Adjust the head restraint so that it is as
close to the head as possible. The center of
the head restraint must support the back of
the head at eye level.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.GWarning!
The power seats can be operated at any time.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.
GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see “Children in the vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/

COMAND system (Y page 208).
GWarning!
You must make sure no one can become
trapped or injured by the moving steering
wheel and driver’s seat when the easy-entry/
exit feature is activated.
To stop seat/steering wheel movement, do
one of the following:
RPress seat adjustment switch.
RMove steering wheel adjustment stalk.
RPress one of the memory position buttons
or the memory button M.
Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.

unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
! Do not activate the easy-entry/exit
feature if the seat backrest is in an
excessively reclined position. Doing so
could cause damage to front or rear seats.

Intermittent wiping
Only switch on intermittent wiping under wet
weather conditions or in the presence of
precipitation.
When you select intermittent wiping, the rain
sensor is activated. The rain sensor sets a
suitable wiping interval depending on the
wetness of the sensor surface automatically.
! Do not leave windshield wipers on an
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers will
operate in the presence of water sprayed
on the windshield, and windshield wipers
may be damaged as a result.
! If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical
effects may cause the windshield wipers to
wipe in an undesired fashion. This could
then damage the windshield wiper blades
or scratch the windshield. You should
therefore switch off the windshield wipers
when weather conditions are dry.
XTurn the combination switch to position
004E or 004F .
After the initial wipe, pauses between
wipes are controlled by the rain sensor
automatically.
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or
out of the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and

The windshield wipers operate with washer
fluid.
i To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with
washer fluid every now and then even when
it is raining.
For information on filling up the washer
reservoir, see “Washer system and headlamp
cleaning system” ( Y page 409).
For information on cleaning the headlamps
with washer fluid, see “Headlamp cleaning
system” ( Y page 303).
Problems with wipers
! If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.
For safety reasons, do the following before
attempting to remove any blockage:
R Stop the vehicle in a safe location.
R Remove the SmartKey from the starter
switch.
or
R Turn off the engine by pressing the
KEYLESS-GO start/stop button and
open the driver’s door (with the driver’s

Power windows
Opening and closing
The door windows are opened and closed
electrically. The switches for all door windows
are located on the driver’s door control panel.
The switches for the respective door windows
are located on the front passenger door and
on the rear doors.
i Operating the rear door windows from
the rear is not possible when you activate
the override switch (Y page 61).
GObserve Safety notes, see page 56.GWarning!
When opening or closing the door windows,
make sure there is no danger of anyone being
harmed by the opening/closing procedure.
The door windows are equipped with the
express operation and automatic reversal
function. If in express operation mode a door
window encounters an obstruction that
blocks its path, the automatic reversal
function will stop the door window and open
it slightly.
The door windows operate differently when
the switch is pulled and held. See the “Closing
when a door window is blocked” section in
this chapter for details.
The closing of the door windows can be
immediately halted by releasing the switch or,
if the switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
Activate the override switch when children
are riding in the back seats of the vehicle. The
children may otherwise injure themselves,
e.g. by becoming trapped in the door window
opening.
GWarning!
Do not keep any part of your body up against
the window pane when opening a window. The
downward motion of the pane may pull that
part of your body down between the window
pane and the door frame and trap it there. If
there is a risk of entrapment, release the
switch and pull it to close the window.
iYou can also open or close the door
windows using the SmartKey, see
“Summer opening feature” (Y page 309)
and “Convenience closing feature”
(Y page 309).
iAfter switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the door windows
until you open the driver’s or front
passenger door. If no door was opened you
can operate the door windows for up to
5 minutes.
