Power tilt/sliding sunroof
Opening and closing
GObserve Safety notes, see page 55.GWarning!
When opening or closing the tilt/sliding
sunroof, make sure there is no danger of
anyone being harmed by the opening/closing
procedure.
The tilt/sliding sunroof is equipped with the
express operation and automatic reversal
function. If the movement of the tilt/sliding
sunroof is blocked during the closing
procedure, the tilt/sliding sunroof will stop
and open slightly.
The tilt/sliding sunroof operates differently
when the sunroof switch is pressed and held.

Garage door opener
The integrated remote control can operate up
to three separately controlled devices
compatible with HomeLink® or some other
systems.
GWarning!
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide (CO),
and inhaling it can cause unconsciousness
and possible death.

The lowest value listed must be selected
when determining how the vehicle and
trailer are loaded.
R The tongue weight at the hitch ball must be
added to the rear axle weight to prevent
exceeding the rear Gross Axle Weight
Rating (GAWR). The GAWR is indicated on
the certification label located on the
driver’s door B-pillar ( Y page 227).
i Mercedes-Benz recommends loading the
trailer in such a manner that it has a tongue
weight between 8 % and 15 % of the GTW.
i The weight of other accessories,
passengers and cargo will reduce the
maximum trailer weight and tongue weight
your vehicle can tow.
Checking weights of vehicle and trailer
R To assure that the towing vehicle and trailer
are in compliance with the maximum
permissible weight limits, have the loaded
rig (towing vehicle including driver,
passengers and cargo, trailer fully loaded)
weighed on a commercial scale.
R Check the vehicle’s front and rear gross
axle weight, the Gross Trailer Weight (GTW)
and tongue weight.
The values as measured must not exceed
the weight limits listed under “Vehicle and
trailer weights and ratings” ( Y page 254).
Coupling a trailer GWarning!
Vehicles with air suspension program: While
you are coupling or decoupling a trailer, make
sure nobody locks or unlocks the vehicle and/
or opens or closes doors or the tailgate.
The vehicle’s level could change and you
could endanger yourself and/or others as a
result.
Make sure that you do not operate the ADS
switch or the vehicle level control system
when coupling/decoupling the trailer.
Observe maximum permitted trailer
dimensions (width and length).
Most states and all Canadian provinces
require
R safety chains between the towing vehicle
and the trailer
The chains should be criss-crossed under
the trailer tongue. They must be attached
to the hitch receiver, and not to the
vehicle’s bumper or axle.
Make sure to leave enough slack in the
chains to permit turning corners.
R a separate brake system at various trailer
weights
R a break-away switch on trailers with a
separate brake system.
Check with your local state laws for specific
requirements.
The switch activates the trailer brakes in
the possible event that the trailer might
separate from the tow vehicle.
! Do not connect a trailer brake system (if
trailer is so equipped) directly to the
vehicle’s hydraulic brake system, as your
vehicle is equipped with antilock brakes. If
you do, neither the vehicle’s brakes nor the
trailer’s brakes will function properly.

damage (i.e. chips from stones, vehicle
doors, etc.).
Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical components
and connectors from contact with water and
cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax should be applied to the
engine compartment after every engine
cleaning. Before applying, all control linkage
bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be
protected from any wax.
Vehicle washing
In the winter, thoroughly remove all traces of
road salt as soon as possible.
When washing the vehicle underbody, do not
forget to clean the inner sides of the wheels.
i Vehicles with KEYLESS-GO:
If a door handle is hit by a strong jet of
water, and a SmartKey is within
approximately 3 ft (1 m) of the vehicle, it
could be inadvertently locked or unlocked.
Hand-wash
XDo not use hot water or wash your vehicle
in direct sunlight.XOnly use a soft, wet cloth or sponge to
clean the vehicle.XOnly use a mild vehicle wash detergent,
such as Mercedes-Benz approved Car
Shampoo.XThoroughly spray the vehicle with a
diffused jet of water.XDo not spray directly towards the
ventilation intake.XUse plenty of water and rinse the sponge
and chamois frequently.XRinse with clean water and dry with a
chamois thoroughly.Do not allow cleaning agents to dry on the
finish.
Automatic car wash
You can have your vehicle washed in an
automatic car wash from the start. Brushless
car washes are preferable.
XTo protect the filter system, activate the air
recirculation mode using button d on
the climate control panel.
! Do not clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting $. Otherwise, the rain
sensor could activate and cause the wipers
to move unintentionally. This may lead to
vehicle damage.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors.
XWhen taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N. Observe
instructions, see “Remaining in neutral
position N” ( Y page 111).
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldings
XFor regular cleaning and care of ornamental
moldings, use a damp cloth.262Vehicle careOperation
