The engine electronics are malfunctioning.
R The fuel supply is malfunctioning.
X Turn the key back to position gin the ignition lock before attempt-
ing to start the engine again.
X Restart the engine (Y page 96). Avoid excessively long and frequent
attemptstos tart the engine, as this (Y page 96) will drain the bat-
tery.
If the engine does not start after several attempts:
X Consult aqualified specialist workshop. The engine does not
start
.The starter motor
can be heard. The yellow reserve fuel warning
lamp is lit and the needle
of the fuel gauge shows
0. The fuel tank is empty.
X Refuel the vehicle.
X Bleed the fuel system (Y page 110).The engine does not
start
.You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 227).
If the engine does not start despite attempt stojump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to excessively high thermal load.
X Allow the starter motor to cool down for approximately two minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult aqualified specialist workshop. The coolant temperature
display is showing more
than 120 †. Adisplay
message may also
appear in the multifunc-
tion display and awarn-
ing tonem ay sound. The coolant level is too low. The coolant is too hot and the engine is not
being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 215). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolan
tlevel is correct, the radiator fan may be faulty. The cool-
ant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below1 20 †, you can continue driving
to the nearest qualifieds pecialist workshop.
X Avoid heavy loadsont he engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. 100

WARNING
If you select the LOW RANGE off-road gearon as lippery road surface, the wheels coul dlose
traction:
R if you release the accelerator peda lwhen
the vehicl eisinmotion
R if Off-road ABS intervenes when braking
If the wheels lose traction, it willnol onger be
possible to steer the vehicle. This increases
the risk of skidding and having an accident.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces.
Information on the parking brake (Y page114).
Downhill gradients Shift to
alower gearing oodt ime on long and
stee pdownhil lgradients.
Take particula rnote of this when driving alad en
vehicl eand when towing atrailer.
Thi sw illu se the braking effect of the engine, so
less braking will be required to maintai nthe
vehicl espeed. Thi srelieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heav yand light loads G
WARNING
The braking system can overheat if you leave you rfoot on the brake peda lwhile driving.
This increases the braking distance and could
even caus ethe braking system to fail .There is
ar isk of an accident.
Never use the brake peda lasafootrest. Do
not simultaneously depress both the brake
peda land the accelerator peda lwhile driving.
! Depressing the brake peda
lconstantly
results in excessive and premature wearto
the brake pads.
If heavy demands are made on the brakes ,do
not park the vehicl eimmediately. Drive on for a
short while. This allows the airflow to cool the
brakes more quickly.
If the brakes have been used only moderately,
you should occasionall ytest their effectiveness.
To do this, brake more firmly from ahigher speed while paying attention to the traffic con-
ditions .This improves the grip of the brakes.
Wet road surfaces If driving in heavy rain for
aprolonge dperiod of
time withou tbraking, there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depres sthe brake pedalm ore
firmly .Maintai nagreater distance from the
vehicle in front.
After driving on awet road or having the vehicle
washed, brake firmly whilep aying attention to
the traffic conditions. This willw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salt-treated roads,
alayer of salt
may form on the brake discs and pads.T his can
increase the braking distance considerably.
R In order to prevent any salt build-up,a pplythe
brakes occasionally whilep aying attention to
the traffic conditions.
R Carefullyd epressthe brake pedalatt he end
of the journey and when starting the next
journey.
R Maintai namuch greater distance to the vehi-
cle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that either are new
or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal.
For safety reasons, Mercedes-Benz recom-
mends only fittingt he following brake discs and
brake pads/linings:
R brake discs that hav ebeena pproved by
Mercedes-Benz
R brake pads/linings that hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle. 116

hot under heavy engine load, e.g. during:
R trailer towing
R longer motorway journeys at high speed
R longer journeys through mountainous ter-
rain
X Let the engine run for approximately another
two minutes while the vehicle is stationary
before switching off the engine.
This way, the exhaust gas turbocharger can

WARNING
If you driv eonas teep incline at an angle or
turn on asteep incline, the vehicl ecoulds lip
sideways, tip and overturn. There is arisk of
an accident.
When driving on an incline, drive into the line of fall (upwards or downward sinastraight
line) and do not turn. G
WARNING
Flammable materia lsuch as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
! There is
arisk of damage to the vehicl eif:
R the vehicl ebecome sstuck, e.g. on ahigh
kerb or an unpaved road
R you drive too quickly over an obstacle, e.g.
ak erb, slowing thresholds or apothol ein
the road
R ah eavy object strikes the underbody or
parts of the chassis
In situations like this, the body ,underbody,
chassi sparts, wheels or tyres coul dbedam-
agedw ithout the damage being visible. Com-
ponents damaged in this way can unexpect-
edlyf ail or, in the case of an accident, no lon-
ger withstand the strain they are designed to withstand.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come into contact with hot parts of the
exhaust system, they can catch fire.
In such situations, have the vehicl echecked
and repaired immediatel yataqualified spe-
cialist workshop. If, on continuing yourj our-
ney, you notice that driving safety is impaired, stop the vehicle immediately
,paying atten-
tion to road and traffic conditions. In such
cases, consult aqualified specialist work-
shop.
! If there are steep gradients while driving off-
road, asufficient filling level in the AdBlue ®
tank must be ensured. Make sure for this rea- son that there is aminimum fill level of ten
litres before driving off-road.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to areduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Cleant he brakes after
driving off-road. If you notice grinding noises or ar eduction in braking performance, have the
brake system checked at aqualified specialist
workshop immediately.A dapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the
conditions of the terrain. Drive carefully.H ave
vehicle damage rectified immediately at aquali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear.

R Make sure that items of luggage and loads are
stowed safely and are well secured
(Y page 203).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Alwaysk eep the engine running and in gear
when driving on adownhill gradient.
R Alwaysk eep the engine running and in gear
when driving on aslope.
R Drive slowly and evenly, if necessary at walk-
ing pace.
R Ensure that the wheels are in contact with the
ground at all times.
R Drive with extreme care on unknown off-road
routes where visibility is poor. For safety rea- sons, get out of the vehicle first and survey
the off-road route.
R Check the depth of water before fording rivers
and streams.
R Watch out for obstacles.
R Alwaysk eep the doors, the rear door, the side
windows and the sliding sunroof closed while
the vehicle is in motion.
R Do not deviate from marked routes.
R Match your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower your speed should be.
R Do not jump with the vehicle. This will inter-
rupt the vehicle's propulsion.
R Avoid high engine speeds. Drive at appropri-
ate engine speeds.
R Alwaysc heck the vehicle for damage after off-
road driving.
Do not use the HOLD function when driving off- road, on steep uphillord ownhill gradients or on
