134Driving and operatingCaution
After running at high enginespeeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Notice
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
Automatic cleaning process
The exhaust filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs between 7 and 12 minutes.
Autostop is not available and fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.
System requires manual cleaning
process
Under certain driving conditions, e.g.
driving short distances, the system
cannot clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be

166Vehicle careCaution
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
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, wellventilated place. Engage first or
reverse gear. Prevent the vehicle from rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and lock the vehicle.
● Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are not functional, e.g. anti-theft
alarm system.
Putting back into operation When the vehicle is to be put back into
operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Activate the electronics
of the power windows.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the engine oil level.
● Check the coolant level.
● Fit the number plate if necessary.End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our
website. Only entrust this work to an
authorised recycling centre.
Gas vehicles must be recycled by a
service centre authorised for gas
vehicles.

206Vehicle care3. Connect the black lead to thenegative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of 1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle The towing eye is stowed with the
vehicle tools 3 186.Adam
1. Disengage the cap by pushing at
the marked position.

208Vehicle careCaution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with manual transmission
automated: the vehicle must only be
towed facing forwards with the front axle raised off the ground.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap and engage in the front
bumper.
Towing another vehicle
Adam
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage. Insert the screwdriver in the slot at the
lower bend of the cap. Disengage the cap by carefully moving the
screwdriver downwards.
The towing eye is stowed with the
vehicle tools 3 186.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
The lashing eye at the rear
underneath the vehicle must never be
used as a towing eye.
Attach a tow rope – or even better a
tow bar – to the towing eye.
The towing eye must only be used for towing and not for recovering a
vehicle.

210Vehicle carea longer time, it would be
damaged by water spotting and
mould growth.All variants:
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can cause paint damage.
If using a car wash, comply with the
car wash manufacturer's instructions. The windscreen wiper 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.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.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.
On vehicles with emblem touchpad:
when cleaning with a high-pressure
jet cleaner ensure a minimum
distance of 30 cm when working
around the tailgate to prevent
unintended unlocking.
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 painted parts of the vehicle
regularly (at the latest when water no longer beads). Otherwise, the
paintwork will dry out.
The foldable sunroof must not be
polished or waxed. When using
automatic car washes, select a
programme without wax additives.
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.
Unpainted plastic body parts must not be treated with wax or polishing
agents.
Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
