Power windows
Opening and closing the windows
The side windows are opened and closed
electrically. The switches for all the side
windows are on the driver’s door. The
switches for the respective windows are
on the front passenger door and the rear
side trim panels.

page 86)
Warning!G
When closing the windows, make sure there
is no danger of anyone being harmed by the
closing procedure.
The closing of the door windows can be im-
mediately halted by releasing the switch or,
if switch was pulled past the resistance
point and released, by either pressing or
pulling the respective switch.
The closing of the rear side windows can be
immediately halted by releasing the switch.
The door windows are equipped with the ex-
press-close and automatic reversal func-
tion. If a door window encounters an
obstruction that blocks its path in a circum-
stance where you pulled the switch past the
resistance point and released it to close the
window, the automatic reversal function will
stop the window and open it slightly.
If a door window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pulling and
holding the switch, by pressing and holding
button ‹on the SmartKey, by pressing
and holding the lock button (vehicles with
KEYLESS-GO*) on an outside door handle,
by operating the soft top switch, or by press-
ing and holding button, ore on the
climate control panel, the automatic rever-
sal function will not operate.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.

305 Operation
Driving instructions
Tires
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16 in (1.6 mm), at which point the
tire is considered worn and should be re-
placed.The treadwear indicator appears as a solid
band across the tread.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subject to extreme operating con-
ditions (e.g. high speeds, heavy loads, high
ambient temperatures).

Turn the SmartKey or the SmartKey with
KEYLESS-GO* to starter switch
position0 and remove, or press
KEYLESS-GO* start/stop button.

Take the SmartKey or the SmartKey with
KEYLESS-GO* with you and lock the
vehicle when leaving.
Warning!G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to
the nearest Mercedes-Benz Center or tire
dealer for repairs.
Warning!G
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately
1/16in
(1.6 mm), we recommend that you do not al-
low your tires to wear down to that level. As
tread depth approaches
1/8in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

Warning!G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious per-
sonal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors can damage to your
health.

not releasing the fuel filler flap, or the opening
mechanism is clamping, notify Roadside Assis-
tance or an authorized Mercedes-Benz Center.

Vehicle care
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Make sure the vehicle’s on-board
electronics have status0 (
page 36).
Fold the wiper arms forward until they
snap into place.
Clean the wiper blade inserts with a
clean cloth and detergent solution.
Use a soft, clean cloth and a mild
window cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is
recommended.Light alloy wheels
If possible, clean wheels once a week.Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light
alloy wheels.!Never open the hood when the wiper arms
are folded forward.
Warning!G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: Make sure the
vehicle's on-board electronics have
status0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.
!Do not pull on the wiper blade inserts. They
could tear.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO
start/stop button (vehicles with KEYLESS-GO*).
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the inside of
the front, rear or side windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an
extended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please drive your vehicle
for several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.
