Breaking-in notes
Important safetyn otes
In certain drivingand drivingsafetysystems, the
sensors adjust automatically while acertain dis-
tance is being driven after the vehicle has been
delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
procedure.
New or replaced brake pads and brake discs
only reach their optimal brakin geffecta fter a
few hundred kilometers of driving. Until then,
compensat efor this by applying greater forcet o
the brake pedal.
The first 1000 miles (1500 km)
For the servicel ife and economy of your vehicle
it is crucial that you break in the engin ewith due
care.
RTherefore, protect the engin efor the first
1000m iles (1500k m) by drivingatv arying
vehicle and engin espeeds.
RAvoid overstraining the vehicle and high
engin espeeds during this period, e.g. driving
at full throttle. Do not exceed Øof the max-
imum speed for each gear.
RDo not change down agear manually in order
to brake.
RTry to avoid depressingt he accelerator pedal
beyond the point of resistance (kickdown).
After 1000m iles (1500km), you can increase
the engin espeed gradually and accelerate the
vehicle to full speed.
iYou should also observet hesenotes on
breaking-in if the engin eorparts of the drive
train on your vehicle have been replaced.

Refueling
Important safety notes
GWARNING
Fuel is highly flammable. Improper handling of
fuel creates arisk of fire and explosion.
Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
engine and, if applicable, the auxiliary heating
before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is arisk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay.Don ot induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildupc an create sparks and

Drive sensibly –save fuel
In order to save fuel, observe the following tips:
XThe tires should alwaysbei nflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main-
tenance Booklet or by the servicei nterval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes ,perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engine running in enclosed spaces with-
out sufficien tventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the man-
ufacturer's specifications. An ywork on the
engine should therefore be carried out by quali-
fied and authorized Mercedes-Benz technicians.
The engine settings must not be changed under
any circumstances. In addition, all specific
maintenanc ework must be carried out at regu-
lar intervals and in accordance with the service
requirement softhe dealer listed here on the
inside title page. Details can be found in the
Maintenance Booklet.
Speed limiter
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is ar isk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load ratin gand speed ratin grequired for
your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the maxi- mum permissible speed based on the tires (tire
and tire pressure). In particular, also observe the tire approval regulations for each country.
You must, under no circumstances, exceed the
speed limit for the tires specified by the speed
index. The speed ratin gisstated in the tire
tables (
Ypage 291).
You can permanently limit the maximum speed
of your vehicle, e.g. for driving on winter tires.

The rear view camera may show obstacles in
perspectival distortion, incorrectly or not at all.
The rear view camera cannot display all objects
located very near and/or under the rear
bumper. It does not warn you ofacollision, per-
sons or objects.
Under the following circumstances, the rear
view camera will not function, or will function in
al imited manner:
Rif the tailgate or rear door is open
Rif it is raining very heavily or snowing, or it is
foggy.
Rat night or in very dark places
Rif the camera is exposed to very bright light.
White lines may appear in the camera image.
Rif the area is lit by fluorescent light or LED
lighting. The camera image may flicker.
Rif the camera lens fogs up, e.g. when driving
into aheated garage in winter, causing arapid
change in temperature.
Rif the camera lens is dirty or obstructed.
Observe the notes on cleaning (Ypage 257).
Rif the rear of the vehicle is damaged. In this
case, have the camera position and setting
checked at aqualified specialist workshop.
Do not use the rear view camera in these situa-
tions. You could otherwise injure others or dam-
age object sand the vehicle while parking and
maneuvering.
The field of vision and other functions of the rear
view camera may be restricted due to additional accessories on the rear of the vehicle (e.g.
license plate holder, rear-mounted bicycle
rack).
Guide lines are alwayss hown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
If you change wheel size, make sure they corre-
spond to the correctw heel size category
(
Ypage 267). If the category is changed without
recoding the control units in the vehicle, the rear
view camera cannot be precisely calibrated. The
guide lines at road level or at the level of the
trailer tow hitch will not be displayed correctly.
In vehicles with atailgate, the rear view camera
is protected from raindrops and dust by means
of aflap. When the rear view camera is activa-
ted, this flap opens.
The flap closes again when:
Ryou have finished the maneuvering process
Ryou switch off the engine For technical reasons, the flap may remain open
briefly after the rear view camera has been
deactivated.
Switching the rear view camera on or
off
XTo switch on: make sure that the key is in
position 2in the ignition lock.
XShift the transmission to position R.
On vehicles with atailgate, the rear view cam-
era flap opens. The audio display shows the
area behind the vehicle. The rear area shown
is divided by guide lines.
In vehicles with atrailer coupling installed, the
function mode of the rear view camera can be
switched over when the trailer is reached. The
rear view camera then changes the viewing
angle and shows alocating aid for the ball cou-
pling of the trailer tow hitch to help reach the
drawbar.
XTo switch function mode: select and con-
firm "Reverse parking" function :or "Cou-
pling up atrailer“ function ;using the audio
system control knob.
Information on the audio system control knob
can be found in the separate operating
instructions.
The symbol of the selected function is high-
lighted.
XTo switch off: shift the transmission to posi-
tion Nor D.
The dynamic guide lines are hidden and after
about 15 sthe rear view camera switches
itself off.

RWhen driving withatrailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing atrailer than when driving
without one. Avoid sudden steerin gmove-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has adecreased
gradient climbing capability and alonger
braking distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the forceont he
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines,
restrict the shift range. Select shift range 4,3,
2 or 1.
Drivin ginal ow gear and at alow speed
reduces the risk of damaging the engine.
RWhen driving on adownhill gradient, shift to a
low gear and take advantage of the engine's
braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditionin gsystem is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switchin gthe airflow and the temperature of
the air conditioning to the maximum level.
Open the windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com- bination you need an additional distance
before you can return to your original lane.
Uncoupling atrailer
GWARNING
If you uncouple atrailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is arisk of injury.
Do not uncouple atrailer if the overrun brake
is engaged.
!Do not disconnect atrailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XMake sure that the selector lever of the auto-
matic transmission is in position P.
XEngage the vehicle's parking brake.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away withawheel chock or similar object.
XRemove the trailer cable and safety chains
and decouple the trailer.
Permissible trailer loads and trailer
drawbar noseweights
Weight information
!For vehicles with apermissible gross vehicle
weight of 6724 lbs (3050 kg), the permissible gross combination weight is less than the sum
of the permissible gross vehicle weight plus
the permissible trailer load. Exceeding the
permitted gross combination weight could
damage the powertrain ,transmission or
trailer tow hitch.
If either the vehicle or the trailer is fully laden,
the permitted gross vehicle weight or the per- mitted trailer load values are reduced accord-
ingly. In this case, you may only partially load
the trailer or the vehicle.
The gross trailer weight (GTW) is calculated by
adding the weight of the trailer to the weight of
the load and equipment. The permissible gross
trailer weight is 5000 lbs (2268 kg).
The maximum noseweight of the trailer drawbar
on the ball coupling is 500 lbs (227 kg). The
actual noseweight may not exceed the value
given on the identification plates of the trailer
tow hitch or the trailer. If the values vary, the
lowest value alwaysa pplies.
The gross combination weight rating (GCWR) is
calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
