24In briefTyre pressure monitoring
system
A pressure sensor is integrated in
each wheel to monitor tyre pressure.
Whilst driving, the current tyre
pressures appear in the Board
Computer menu.
Deviating tyre pressure is displayed
in the form of a message in the
Info-Display.
Tyre pressure monitoring system
3 174.
Adaptive Forward Lighting
The system improves lighting of
curves and increases the headlight
range.
The beam pivots based on steering
wheel position and vehicle speed.
At higher speeds and continuous straight ahead travel, the beam
automatically raises slightly, thereby
increasing headlight range.
Adaptive forward lighting 3 110.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving. The filter
is cleaned by burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may take up to 25 minutes. Fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.

To replace the battery, press the
locking mechanism and remove the
cap by applying light pressure. Press
the cap on the other side outward.
Replace the battery (battery type
CR 2032), noting the installation
position. Engage caps.
Radio remote control
synchronisation
The radio remote control
synchronises itself automatically
during every starting procedure.
Fault
If the central locking cannot be
operated or the engine cannot be
started, the cause may be one of the
following:
■ Fault in remote control 3 27,
■ electronic key out of reception range.
To rectify the cause of the fault,
change the position of the electronic
key.
Central locking system Unlocks and locks doors, load
compartment and fuel filler flap.
A pull on an interior door handle
unlocks the entire vehicle and opens
the door.
Notice
In the event of an accident of a
certain severity, the vehicle unlocks
automatically.Unlocking

Instruments and controls101Engine cooling level
Low fluid level in engine cooling
system. Check coolant level 3 154.
Drain diesel fuel filter If there is water in the diesel fuel filter,
the message InSP4 appears in the
instrument panel. Consult a
workshop.
Lighting
Important exterior lights, including
cables and fuses, are monitored. In
trailer mode, trailer lighting is also
monitored. Trailers with LED lighting
must have an adapter that enables
light monitoring as with conventional
bulbs.
The failed lighting will be indicated in
the information display or the
message InSP2 will appear in the
instrument panel display.
Anti-theft alarm system
System fault in anti-theft alarm
system. Have the cause of the fault
remedied by a workshop.
Tyre pressure
On vehicles with tyre pressure
monitoring system, if there is low tyre pressure, information which tyre to
check appears on the display.
Reduce speed and check tyre
pressure at the next opportunity. Tyre
pressure monitoring system 3 174.
Check tyre pressure 3 173, 3 205.

102Instruments and controls
If there is a considerable loss of
pressure, a corresponding message
appears indicating the tyre.
Steer out of flow of traffic as quickly as possible without endangering
other vehicles. Stop and check the
tyres. Mount the spare wheel 3 180.
If run-flat tyres are fitted, maximum
speed is 50 mph. Information 3 172.
Tyre pressure monitoring system

Washer fluid level
Low washer fluid level. Top up
washer fluid 3 155.
Trip computer
Trip computer in Board-Info-Display
Access the data by pressing the BC
button on the Infotainment system or
the left adjuster wheel on the steering wheel.
Some information appears in the
display in an abbreviated form.
Once an audio function has been
selected, the lower row of the trip
computer function is displayed
furthermore.Instantaneous consumption
Displays the instantaneous
consumption. At low speeds,
consumption per hour is displayed.
Average consumption
Displays average consumption. The
measurement can be reset at any
time.
Absolute consumption
Displays fuel consumed. The
measurement can be reset at any
time.

Accessories and vehicle
modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
Following must be done if the vehicle
should be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.

174Vehicle care
Remove the valve cap key from the
fuel filler flap and use it to unscrew the
valve cap.
On vehicles with tyre pressure
monitoring system, screw the adapter
to the valve.
Tyre pressure 3 205 and on the label
on the inside of the fuel filler flap.
The tyre pressure data refer to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare wheel to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible. It must not be used with run-flat tyres.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify drive axle and body style.
2. Identify the engine identifier code.
Engine data 3 200.
3. Identify the respective tyre.The tyre pressure tables show all
possible tyre combinations 3 205.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Tyre pressure monitoring
system
The tyre pressure monitoring system
continually checks the pressure of all
four wheels when vehicle speed
exceeds a certain limit.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.

188Vehicle care
If using a car wash, comply with the
car wash manufacturer's instructions. The windscreen wipers and rear
window wiper must be switched off.
Remove antenna and external
accessories such as roof racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois leather together with window cleanerand insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Moonroof
Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the middle part of the
moonroof.
