Working on the vehicleGWarning!
When working on the vehicle, engage the
parking brake and shift the automatic
transmission into park position P. Otherwise
the vehicle could roll away which could result
in an accident and/or serious personal injury.
Towing a trailer
XWhen you tow a trailer, shift into a lower
gear range manually if the automatic
transmission hunts between gears on
inclines.
A lower gear range and reduction of speed
reduces the potential to overload or to
overheat the engine.
For more information on trailer towing, see
“Trailer towing” (Y page 246).
Gear ranges
With the automatic transmission in drive
position D, you can limit or extend the gear
range, see “One-touch gearshifting”
(Y page 107).
The current gear range appears in the
multifunction display.

Opening and closing the panorama
roof with power tilt/sliding panel
GObserve Safety notes, see page 53.GWarning!
When opening or closing the tilt/sliding panel,
make sure there is no danger of anyone being
harmed by the opening/closing procedure.
The tilt/sliding panel is equipped with the
express operation and automatic reversal
function. If the movement of the tilt/sliding
panel is blocked during the closing procedure,
the tilt/sliding panel will stop and open
slightly.
The tilt/sliding panel operates differently
when the roof panel switch is pressed and
held. See the “Closing when the tilt/sliding
panel is blocked” section in this chapter for
details.
The opening/closing procedure of the tilt/
sliding panel can be immediately halted by
releasing the roof panel switch or, if the roof
panel switch was moved past the resistance
point and released, by moving the roof panel
switch in any direction.
GWarning!
The panorama roof with tilt/sliding panel 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 panel.
Do not open the tilt/sliding panel if there is
snow or ice on the roof, as this could result
in malfunctions.
! Please keep in mind that weather
conditions can sometimes change rapidly.
Make sure to close the tilt/sliding panel
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.

Loading and storing
Loading instructions
GWarning!
Always fasten items being carried as securely
as possible using cargo tie-down rings 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.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Load distribution
The Gross Vehicle Weight (GVW) is the weight
of the vehicle including:Rfuel
Rtools
Rspare wheel
Rinstalled accessories
Rpassengers

It must never exceed the load limit and the
Gross Vehicle Weight Rating (GVWR) for your
vehicle. The load limit and the GVWR are
specified on the placard located on the
driver’s door B-pillar (Y page 227).
In addition, the load must be distributed so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR for
your vehicle are indicated on the certification
label located on the driver’s door B-pillar
(Y page 227).
For more information, see “Tire and Loading
Information” (Y page 228).
The handling characteristics of a fully loaded
vehicle depend greatly on the load
distribution. It is therefore recommended to
