140Driving and operatingGuide lines (3, 4, 5) are used together
with the fixed lane display (2) and
indicate the distance behind the
vehicle.
The guide line intervals are as
follows:3 (red):30 cm4 (yellow):70 cm5 (green):150 cm
Settings
Settings, e.g. brightness, contrast
and colours can be changed via the
Infotainment system. The feature
may also be switched off
permanently. Refer to Infotainment
system manual for further
information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged
for approx. 5 seconds.
Fault
The rear view camera may not
operate properly when:
● the surrounding is dark
● the sun or the beam of headlights
is shining directly into the camera
lens
● ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth
● the rear doors/tailgate are not closed correctly
● the vehicle had a rear-end accident
● there are extreme temperature changesFuel
Fuel for diesel engines Only use diesel fuel that complies
with EN 590. The fuel must have low
sulphur content (max. 10 ppm).
Equivalent standardised fuels with a
biodiesel (= FAME according to
EN14214) content of max. 7% by
volume (like DIN 51628 or equivalent
standards) may be used.
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 to EN 590 or similar can lead to
engine powerloss, 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.

Vehicle care145General Information
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 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 vehicle in a dry, well ventilated 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.Putting back into operation
When the vehicle is to be put back into
operation:
● 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.

Vehicle care147Caution
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 3 182.
The maximum engine oil
consumption is 0.6 l per 1000 km.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 10 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.
When the engine oil level has
dropped to the MIN mark, top-up
engine oil.
Caution
Do not allow the engine oil level to drop below the minimum level!
We recommend the use of the same
grade of engine oil that was used at
the last change.
The engine oil level must not exceed the maximum mark MAX on the
dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
To prevent spillage when
replenishing the engine oil, we
recommend using a funnel to top-up the engine oil. Ensure funnel is
securely located onto the filler pipe.

152Vehicle careWarning 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 battery.
Diesel fuel filter
The diesel fuel filter is accessible from the underside of the vehicle.
Drain filter of residual water at every
engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screw on the lower part of the filter by approx. one turn, to drain off the
water.
The filter is drained as soon as water-
free diesel fuel emerges. Retighten
the screw.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
Refuel then proceed as follows:
With ignition key

Vehicle care173Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel. Spare wheel 3 173.
7. Screw in the wheel bolts.
8. Lower the vehicle and remove jack.
9. Tighten each of the wheel bolts in
a crosswise sequence using the
wheel wrench. Ensure the wrench
locates securely. The wrench
should turn clockwise to tighten
the bolts. Invert the wrench if
necessary.
Tightening torque is 160 Nm.
10. Replace the wheel cover, ensuring that the valve hole in thewheel cover is aligned with the
tyre valve before installing.
Notice
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel
cover).11. Stow the replaced wheel 3 173
and the vehicle tools 3 163.
12. Have the new wheel balanced on the vehicle.
Check the tyre pressure of the
installed tyre 3 198.
Check the wheel bolt torque.
Have the defective tyre renewed or
repaired as soon as possible.
Spare wheel
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 169.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
It may be necessary to jack the
vehicle up to gain access to the spare
wheel on a fully loaded vehicle with a
flat rear tyre.
