If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
The language setting for the multifunction
display can be changed with the audio system
(Y page 136) or with the COMAND system.
Vehicles with COMAND system: Refer to
separate operating instructions.
Activating the instrument cluster
The instrument cluster is activated when you
Ropen the driver’s door
Rswitch on the ignition
Adjusting the instrument cluster
illumination
XTo brighten illumination: Turn
dimmer : clockwise.
XTo dim illumination: Turn dimmer :
counterclockwise.
iThe instrument cluster illumination is
dimmed or brightened automatically to suit
ambient light conditions.
The instrument cluster illumination will also
be adjusted automatically when you switch
on the vehicle’s exterior lamps.
Coolant temperature gauge
The coolant temperature gauge is located on
the left side in the instrument cluster
(Y page 28).
GWarning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†), i.e close to the
red zone of the temperature gauge.
! Excessive coolant temperature triggers a
warning in the multifunction display.
The engine should not be operated with a
coolant temperature above 248‡ (120†),
i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
Tachometer
The red marking on the tachometer
(Y page 28) denotes excessive engine speed.
! Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
To help protect the engine, the fuel supply is
interrupted if the engine is operated within
the red marking.

Outside temperature indicator
The outside temperature indicator is
displayed in the multifunction display
(Y page 112).
GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster (Y page 28). Once the fuel
level has fallen below the reserve mark, the
yellow fuel tank reserve warning lamp 8
for the fuel reserve comes on.
Control system
Introduction
The control system is activated as soon as the
starter switch is in position 2.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to call up statistical
data on your vehicle, and much more.
GWarning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
The control system relays information to the
multifunction display.
Multifunction steering wheel
The displays in the multifunction display and
the settings in the control system are
controlled by using the buttons on the
multifunction steering wheel.

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
Rluggage/cargo
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
load the vehicle according to the illustration

features described in this manual.
The first 1000 miles (1500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satisfied
you will be with its performance later on.
R Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.
R During this period, avoid heavy loads (full
throttle driving) and excessive engine
speeds (no more than 2
/ 3 of maximum rpm
in each gear).
R Select C as the preferred shift program
( Y page 106) for the first 1 000 miles

R Avoid accelerating by kickdown.
R Do not attempt to slow the vehicle down by
shifting to a lower gear using the gear
selector lever.
R Select gear ranges 3, 2 or 1 (Y page 106)
only when driving at moderate speeds (for
hill driving).
After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine speeds
to the permissible maximum.
All of the above instructions, as may apply to
your vehicle type, also apply when driving the
first 1 000 miles (1 500 km) after the engine,
the transfer case, the front differential or the
rear differential have been replaced.

Refueling
GWarning!
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.
GWarning!
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray back out when removing the fuel pump
nozzle, which could cause personal injury.
! Never refuel vehicles with gasoline engine
with diesel fuel. Even small amounts of
diesel fuel will damage the fuel system and
engine. Damage resulting from the use of
non-approved fuels or fuel additives or
resulting from mixing gasoline with diesel
fuel is not covered by the Mercedes-Benz
Limited Warranty.
! If you have accidentally filled the tank
with incorrect or non-approved fuel, do not
switch on the ignition. Otherwise the
incorrect or non-approved fuel will get into
the fuel lines. The fuel system must be
drained completely. Contact an authorized
Mercedes-Benz Center to have the fuel
system drained completely.
! To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
