144Driving and operatingCaution
Certain additives in petrol could, in
combination with ethanol, cause
reduced driveability. For this
reason, refuel with a full tank of
petrol every 6000 miles. 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 a
workshop.
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 20.
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.

Vehicle care151
■ 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.

152Vehicle careBonnetOpening
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 3 120.
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.
Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.
Page 155 of 217

Vehicle care153
Insert dipstick to the stop on the
handle and make half a turn.
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 87, low engine oil S
3 88 and engine oil life C 3 88.
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.

Charging the vehicle battery9Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed
14.6 volts when using a battery
charger. Otherwise the vehicle
battery might be damaged.
Jump starting 3 187.
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
information.
■ Explosive gas may be present in the vicinity of the vehicle battery.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

4. Before positioning the jack, set itto the necessary height by
rotating the eye by hand.
Position jack at the jacking point
located nearest to the wheel concerned so that the jack claw
spans the vertical base. Ensure
the jack is positioned correctly.
The jack base must be on the
ground directly below the jacking
point in a manner that prevents it
from slipping.5. Attach wheel wrench to eye of threaded rod and rotate wrench
clockwise to raise vehicle.
If this is not the case, carefully
lower the vehicle immediately and
reposition the jack. Raise the
vehicle until the wheel is just clear of the ground.
6. Unscrew wheel nuts completely and wipe clean with a cloth.
Do not grease the threads. Put
wheel nuts somewhere where the threads will not be soiled.
7. Change the wheel. Notes on spare wheel 3 185.
8. Screw on the wheel nuts and
tighten slightly by hand by turning
clockwise until wheel is held
against the hub.
9. Rotate wrench anticlockwise and lower vehicle to the ground.
10. Install the wheel wrench ensuring that it locates securely and tighten
each wheel nut in a crosswise
sequence. Tightening torque is
140 Nm.
11. Stow the replaced wheel 3 185
and the vehicle tools 3 173.
12. Check the tyre pressure of the installed tyre as soon as possible.
