Driving and operating145Caution
Certain additives in petrol could, in
combination with ethanol, cause
reduced driveability. For this
reason, refuel with a full tank of
petrol every 10000 km. Use up the majority of this before refuelling
the car again.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.
Caution
Use of fuel that does not comply
with EN 590 or similar can lead to engine power loss, increased
wear or engine damage and loss
of warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by an
authorized dealer.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at left rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked 3 21.
Release the fuel filler flap by pushing the flap.
To unlock fuel filler cap: turn it
anticlockwise. If hissing occurs, wait
until it stops before completely
unscrewing the cap.

Accessories and vehicle
modifications
We recommend the use of 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
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.
■ 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, well ventilated place. Engage first orreverse gear or move selector lever
to P. Prevent the vehicle from
rolling.
■ Do not apply the electrical parking brake.

152Vehicle care
■ Open the bonnet, close all doorsand 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, where legally required. Only
entrust this work to an authorised
recycling centre.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
9 Danger
The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.

Vehicle care153Bonnet
Opening
Pull the release lever and return it to
its original position.
Locate the safety catch, found slightly left of centre on the underside of the
bonnet, push the catch upwards and
lift the bonnet gently.
The bonnet is held open
automatically.
If the bonnet is opened during an Autostop, the engine will be restarted automatically for safety reasons.
Air intake 3 121.
Closing
Lower the bonnet and let it fall into the latch from a low height (20-25 cm).
Check that the bonnet is engaged.
Caution
Do not press the bonnet into the
latch to avoid dents.
Engine oil
Check the engine oil level manually on a regular basis to prevent damage
to the engine.
Ensure that the correct specification
of oil is used. Recommended fluids
and lubricants 3 195.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.
Pull out the dipstick, wipe it clean, insert it to the stop on the handle, pull
out and read the engine oil level.
Insert dipstick to the stop on the
handle and make half a turn.
Page 156 of 217

154Vehicle care
Different dipsticks are used
depending on engine variant.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.We recommend the use of the same
grade of engine oil that was used at
the last oil change.
The engine oil level must not exceed
the MAX mark on the dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 206, Engine oil quality/
viscosity 3 195.
Fit the cap on straight and tighten it.
Control indicators for engine oil
pressure I 3 88, low engine oil S
3 89 and engine oil life C 3 89.
Once the engine oil has been
changed, the engine oil life monitor
needs to be reset. Seek the
assistance of a workshop.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.

Warning label
Meaning of symbols:■ No sparks, naked flames or smoking.
■ Always shield eyes. Explosive gases can cause blindness or
injury.
■ Keep the vehicle battery out of reach of children.
■ The vehicle battery contains sulfuric acid which could cause
blindness or serious burn injuries.
■ See the Owner's Manual for further

Diesel fuel filter
Drain diesel fuel filter of residual
water at every engine oil change.
Place a container underneath the
filter housing. Turn drain plug
anticlockwise using a suitable
screwdriver, to drain off the water.
The filter is drained as soon as diesel fuel emerges from the port. Retighten
the drain plug by turning it clockwise.
With engine switched off, turn ignition
key to ON, wait approx. 5 seconds,
and turn key to LOCK to perform
priming operation. Perform this
operation 3 times or more while the
engine is switched off, to avoid air
entering the fuel line.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
If there is water in the diesel fuel filter, control indicator U illuminates in the
instrument cluster 3 90. Drain the
water immediately.
Diesel fuel system
bleeding
If the fuel tank has been run dry, the
diesel fuel system must be bled.
Switch on the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds. If the engine will not start, wait at least 10 seconds before trying
again. If the engine fails to start, seek
the assistance of a workshop.

3. Connect the black lead to thenegative terminal 3 of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block 4 or an
engine mounting bolt. Connect as far away from the discharged
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 start.
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. Operate discharged vehicle for approx. 20 minutes to allow for
adequate battery recharging.
6. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Remove the spoiler lip from the front
left-hand side of the vehicle by
unfastening the six screws located on the underside of the vehicle. Then
attach the towing eye.
The towing eye is stowed with the
vehicle tools 3 173.
