Power tilt/sliding sunroof
Opening and closing
GObserve Safety notes, see page 56.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.
See the “Closing when the tilt/sliding sunroof
is blocked” section for details.
The opening/closing procedure of the tilt/
sliding sunroof can be immediately halted by
releasing the sunroof switch or, if the sunroof
switch was moved past the resistance point
and released, by moving the sunroof switch in
any direction.
GWarning!
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury for
occupants wearing their seat belts properly as
entire body parts or portions of them may
protrude from the passenger compartment.
! To avoid damaging the seals, do not
transport any objects with sharp edges
which can stick out of the tilt/sliding
sunroof.
Do not open the tilt/sliding sunroof if there
is snow or ice on the roof, as this could
result in malfunctions.
If you cannot open or close the tilt/sliding
sunroof due to a malfunction contact
Roadside Assistance or an authorized
Mercedes-Benz Center.
! Please keep in mind that weather
conditions can sometimes change rapidly.
Make sure to close the tilt/sliding sunroof
when leaving the vehicle. If water enters
the vehicle interior, vehicle electronics
could be damaged which is not covered by
the Mercedes-Benz Limited Warranty.
i You can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO function, see “Summer
opening feature” ( Y page 309) and
“Convenience closing feature”
( Y page 309).
i After switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the tilt/sliding
sunroof until you open the driver’s or front
passenger door. If no door was opened you
can operate the tilt/sliding sunroof for up
to 5 minutes.Power tilt/sliding sunroof373Controls in detail221_AKB; 6; 20, en-USd2ugruen,Version: 2.11.8.12009-09-24T13:28:17+02:00 - Seite 373Z

Loading and storing
Loading instructions
GWarning!
Always fasten items being carried as securely
as possible using cargo tie-down hooks and
fastening materials appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
The trunk is the preferred place to carry
objects. Always use cargo tie-down hooks
when transporting cargo. Do not place
anything on the rear-window shelf.
Never drive a vehicle with the trunk open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Load distribution
The total load weight including vehicle
occupants and luggage/cargo should not
exceed the total load limit indicated on the

there is enough clearance and that the
floormats are securely fastened.
Floormats should always be securely fastened
using the fastening equipment.
Before driving off, check that the floormats
are securely in place and adjust them if
necessary. A loose floormat could slip and
hinder proper functioning of the pedals.

Always use winter tires at temperatures
below 45‡ (7†) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake 004Dmarking on the tire sidewall.
These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the
only way to achieve the maximum
effectiveness of your vehicle’s driving safety
systems such as the ABS and the ESC in
winter operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the “Technical data”
section ( Y page 532).
Always observe the speed rating of the winter
tires installed on your vehicle.
After installing winter tires:XCheck the tire inflation pressure and adjust
it if necessary ( Y page 413).XRestart the Advanced Tire Pressure
Monitoring System ( Y page 414).
Snow chains
! When driving with snow chains, always
select the raised level of the vehicle level
control. Other settings may result in
damage to your vehicle.
! Some tire sizes do not leave adequate
clearance for snow chains. To help avoid
serious damage to your vehicle or tires,
make sure the use of snow chains is
permissible as specified in the “Technical
data” section of this Operator’s Manual.
Snow chains should only be driven on snow-
covered roads at speeds not to exceed
30 mph (50 km/h). Remove chains as soon
as possible when driving on roads without
snow.
Observe the following guidelines when using
snow chains:
R Use of snow chains is not permissible with
all wheel/tire combinations ( Y page 532).
R Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
! If snow chains are mounted to the front
wheels, they may scrape against the body
or axle components. The tires or the vehicle
could be damaged as a result.
R Only use snow chains that are approved by
Mercedes-Benz. Any authorized Mercedes-
Benz Center will be glad to advise you on
this subject.
R Use of snow chains may be prohibited
depending on location. Always check local
and state laws before installing snow
chains.
R Do not use snow chains on the spare wheel.
i When driving with snow chains, you may
wish to switch off the ESC ( Y page 232)
before setting the vehicle in motion. This
will improve the vehicle’s traction.
Winter driving instructions
GWarning!
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
