168Driving and operatingdiesel, Aquazole and similar diesel-
water emulsions. Diesel fuels must not be diluted with fuels for petrol
engines.
The flow and filterability of diesel fuels are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
Diesel fuel filter  3 182, diesel fuel
system bleeding  3 183.
Low temperature operation
At temperatures below 0° C, some
diesel products with biodiesel blends
may clog, freeze or gel, which may
affect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0°C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20° C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor
starting or damage on the fuel
injection system.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.
The fuel tank filler neck with bayonet
cap is located on the left front side of
the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the door is opened. Open the fuel filler flap by
hand.9 Danger
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to
avoid risk of engine being
restarted automatically by the
system.

170Driving and operatingTrailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust fitting of towing equipment at
a later date to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the breakaway stopping cable.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability the use of a
stabiliser is recommended.
A maximum speed of 50 mph must
not be exceeded, even in countries
where higher speeds are permitted.If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load  3 244.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle-dependent and engine-
dependent maximum values which
must not be exceeded. The actual
trailer load is the difference between
the actual gross weight of the trailer
and the actual coupling socket load
with the trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In
general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 metres above sealevel. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3  223.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim for the maximum load, especially in the case of heavy trailers. The
vertical coupling load should never
fall below 25 kg. 

Vehicle care175End-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 vehicle must not be in an
Autostop  3 135.
The cooling fan may start
operating even if the ignition is off.
9 Danger
The ignition system generates
extremely high voltages. Do not
touch.
The caps for topping up the engine oil, the coolant, the washer fluid and the
oil dipstick handle are yellow for ease
of identification.
Bonnet
Opening
Pull the release lever and return it to
its original position. 

176Vehicle care
Pull the safety catch, located slightly
left of centre, and open the bonnet.
Pull up the support rod from its holder,
then secure it in the right side hook on the underside of the bonnet.
If the bonnet is opened during an Autostop, the engine will be restarted
automatically for safety reasons.
Stop-start system  3 135.Caution
Ensure the windscreen wiper is
switched off before opening the
bonnet  3 84.
Closing
Before closing the bonnet, press the
support into the holder.
Lower the bonnet and allow it to drop into the catch 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.
9 Warning
In the event of even a minor head-
on collision, have the bonnet
safety catch checked by a
workshop.
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  3 220.
The maximum engine oil
consumption is 0.6 litres per
600 miles.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least ten minutes. 

180Vehicle careBrakesIn the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake linings replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe  MIN  and  MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.
Only use brake fluid approved for
your vehicle.
Brake and clutch fluid  3 220.
Vehicle battery
The jump start terminal is located in
the engine compartment.
Jump starting  3 212.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Control indicator  p illuminates if
there is a fault with the charging
system. Stop, switch off engine and
seek the assistance of a workshop.
Charging system  3 96.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery. 

Vehicle care1819Danger
Ensure the ignition is switched off
completely (the vehicle must not
be in an Autostop) before
connecting or disconnecting the
vehicle battery.
Stop-start system  3 135.
The anti-theft alarm siren must be
deactivated as follows: Switch the ignition on then off, disconnect the
vehicle's battery within 15 seconds.
Battery discharge protection  3 114.
Battery access
The battery is located behind a panel in the front left-hand door step.
Remove the panel to access the
battery.
Replacing the vehicle battery Ensure that the battery is always
replaced by the same type of battery.
Seek the assistance of a workshop to
have the vehicle battery replaced.
Stop-start system  3 135.
Charging the vehicle battery9 Warning
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.
9 Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
