Vehicle care
Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water.
Direct only a very weak spray towards
the ventilation intake.
Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
To protect the filter system, switch the
automatic climate control to air recir-
culation mode (
page 190) or
(
page 191).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!Make sure that the windshield wiper switch
is set to 0(
page 56). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent dam-
age to the mirrors.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 338). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may vi-
brate.
!Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome clean-
er. If in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.

non-scratching cloth to clean sensor
cover1.
Restart the engine after cleaning sen-
sor cover1.
Cleaning the Parktronic* system
sensors
1Parktronic system* sensors in the front
bumper
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water and a soft,
non-scratching cloth to clean
sensors1 on the bumpers.
!Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, do not use abrasives, solvents or cleaners
that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.
!To prevent scratches or damage, never ap-
ply strong force and only use a soft, non-scratch-
ing cloth when cleaning the sensor cover1. Do
not attempt to wipe dirty sensors with a dry cloth
or sponge.

338 Operation
Vehicle care
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Switch on the ignition (page 38).
Turn combination switch to wiper
settingu (
page 56).
With wiper arms in vertical position,
switch off the ignition (
page 60).Fold the wiper arms forward until they
snap into place.
Clean the wiper blade inserts with a
clean cloth and detergent solution.
Use a soft, clean cloth and a mild win-
dow cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is recom-
mended.
!Do not apply strong pressure to the sensor
covers. Applying strong pressure may damage
the sensor covers.
Follow the instructions provided by the power
washer manufacturer on maintaining a distance
between the vehicle and the nozzle of the power
washer.
!To prevent scratches, never apply strong
force and only use a soft, non-scratching cloth
when cleaning the sensors. Do not attempt to
wipe dirty sensors with a dry cloth or sponge.
!The windshield wipers must be in a vertical
position before folding them away from the wind-
shield. They could otherwise damage the hood.
Never open the hood when the wiper arms are
folded forward.
Warning!G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch (vehi-
cles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have
status0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.
!Do not pull on the wiper blade inserts. They
could tear.

DISTRONICCurrently Unavailable
See Operator’s ManualDistronic* is switched off and is tempo-
rarily unavailable.
Distronic* is deactivated if:

the Distronic* cover in the radiator
grille is dirty

its function is impaired by heavy pre-
cipitation or fog
If necessary, clean the Distronic* cover in the
area of the radiator grille (
page 337).
Restart the vehicle.
or
Distronic* becomes operational again without the
engine being restarted when:

dirt on the radiator grille has fallen off while
driving (e.g. slush or snow)

the system recognizes full sensor availability
(due to lessening rain or the road surface dry-
ing)

the message in the multifunction display disap-
pears

the speed last stored flashes in the display for
5 seconds.
You can operate Distronic* as usual again.

Display messagePossible cause/consequencePossible solution
DISTRONICCurrently Unavailable
See Operator’s ManualDistronic* is deactivated because the
functionality is impaired by external in-
terferences, e.g. high-frequency sources
such as too stations, speed measuring
systems etc.Leave the area of the external interference.
Activate Distronic* again (page 222) when
the message

pears.
Distronic* is deactivated because the
Distronic* sensor has not sensed any
other vehicles or objects, e.g. road sign
or such, for a long time.Activate Distronic* again (page 222) when
the message
DISTRONIC available again ap-
pears.
ESPInoperative
See Operator’s Man.The ESP® as well as BAS and PRE-SAFE®
have detected a malfunction and
switched off.
The ABS may not be operational.
The brake system is still functioning nor-
mally but without the ABS, BAS, ESP
®
and PRE-SAFE® available.
Continue driving with added caution.
Have the system checked at an authorized
Mercedes-Benz Center as soon as possible.
Failure to follow these instructions increases the
risk of an accident.
Warning!G
Distronic cannot take weather conditions
into account. Switch off Distronic* or do not
turn it on if the sensor is dirty or visibility is
diminished as a result of snow, rain or fog.
The distance control may be impaired even
before the system is able to detect a dirty
sensor. The messageDISTRONIC

418 Practical hints
Flat tire
Detach the electric air pump.
Stow electrical plug3 and air hose4
behind flap1 and place the air pump
back in the trunk.Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.
Remove the jack.
1-5 Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).
Before storing the jack in the trunk, it
should be fully collapsed.
Warning!G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes, etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
iVehicles with Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor (
page 309) until a full size wheel/tire with
functioning sensor has been placed back into
service on the vehicle.
Warning!G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).
iWrap the damaged wheel in the protective
film that comes with the spare wheel and put the
wheel in the trunk.
You can also place the damaged wheel down into
the spare wheel well. In this case, you must stow
the luggage bowl in the trunk.
