vehicle.GWARNING
The fuel line or the fuel tank is faulty.
Risk of explosion or fire.
XApply the electric parking brake.
XSwitch off the engine.
XRemove the SmartKey from the ignition lock.
or, on vehicles with KEYLESS‑GO:
XOpen the driver's door.
The on-board electronics now have status 0. This is the same as
the SmartKey having been removed.
XDo not restart the engine under any circumstances.
XConsult a qualified specialist workshop.

pletely dry.
XRefuel the vehicle with at least 5.3 US qt (5 liters) of diesel.
XTurn the ignition on for approximately ten seconds
(
Ypage 165).
XStart the engine continuously for up to ten seconds until it runs
smoothly.
If the engine does not start:

water. Seek medical assistance without
delay.
RChange out of clothing contaminated with
DEF immediately.
!Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
!The vehicle must be parked on level
ground to fill the DEF tank. The DEF tank
can only be filled as intended with the vehi-
cle parked on a level surface. This avoids
false level readings. Filling the tank is not
permitted if the vehicle is not parked on a
level surface. There is a danger of overfill-
ing, which could result in damage to com-
ponents of the BlueTEC exhaust gas after-
treatment.
!Rinse surfaces that have come into con-
tact with DEF immediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clean it. DEF
residues crystallize after time and contam-
inate the affected surfaces.
!DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine dam-
age.
For further information on DEF, see
(
Ypage 450).
Opening the DEF filler cap
The fuel filler flap is unlocked or locked auto-
matically when you open or close the vehicle
with the SmartKey or with KEYLESS-GO.
XSwitch the ignition off.
XPress the fuel filler flap in the direction of
arrow :.
The fuel filler flap swings up.
XTurn blue DEF fuel filler cap ;counter-
clockwise and remove it.
DEF filler cap ;is secured with a plastic
strip.
DEF refill canisters
!Do not tighten the disposable hose with
too much force. The disposable hose may
otherwise be destroyed.
XUnscrew the cap from the opening on top of
DEF refill canister ;.
XPlace disposable hose :on the opening of
DEF refill canister ;and screw it on clock-
wise until hand-tight.

Checking coolant level
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
XPark the vehicle on a level surface.
Only check the coolant level when the vehi-
cle is on a level surface and the engine has
cooled down.
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 165).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (
Ypage 165).
XCheck the coolant temperature gauge in
the multifunction display.
The coolant temperature must be below
158 ‡ (70 †).
XTurn the SmartKey to position 0in the igni-
tion lock (
Ypage 165).
XSlowly turn cap :half a turn counter-
clockwise and allow excess pressure to
escape.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar =in the filler
neck when warm, there is enough coolant
in expansion tank ;.
XIf necessary, add coolant that has been tes-
ted and approved by Mercedes-Benz.
XReplace cap:and turn it clockwise as far
as it will go.

Maintenance and care

Do not remove the SmartKey from the
ignition lock. Do not open the driver's
door or front-passenger door when the
engine is switched off. Otherwise, the
automatic transmission selects park
positionPautomatically and locks the
wheels. You can prevent this by shifting
the automatic transmission to Nbefore-
hand.
RVehicles with KEYLESS-GO:
Do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position N:
XMake sure the vehicle is stationary and the
ignition is switched off.
XTurn the SmartKey to position2in the igni-
tion lock (
Ypage 165).
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.
XDepress and hold the brake pedal.
XShift the automatic transmission to posi-
tion N.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch off the ignition and leave the Smart-
Key in the ignition lock.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is ver y d
irty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
shield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays. Observe the legal requirements in all coun-
tries concerned.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with a
gentle jet of water.
XDo not point the water jet directly towards
the air inlets.
XUse plenty of water and rinse out the
sponge frequently.
XRinse the vehicle with clean water and dry
thoroughly with a chamois.
XDo not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.
Do not aim directly at any of the following:
Rtires
Rdoor gaps, roof gaps, joints, etc.

XVehicles with the ON&OFFROAD pack-
age: make sure that highway level is selec-

XMake sure that the passengers are not
endangered as they do so. Make sure that
no one is near the danger area while a
wheel is being changed. Anyone who is not
directly assisting in the wheel change
should, for example, stand behind the bar-
rier.
XGet out of the vehicle. Pay attention to traf-
fic conditions when doing so.
XClose the driver's door.
XUnload heavy luggage.
iOnly operate the tire inflation compressor
using a 12 V socket, even if the ignition is
turned off (
Ypage 353).
An emergency cut-out ensures that the on-
board voltage does not drop too low. If the on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine.
MOExtended tires (tires with run-flat
properties)
General notes
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
(
Ypage 421).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
