146Driving and operatingTrailer hitch
General information
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Control indicator á illuminates in the
instrument cluster when a trailer is
connected to the vehicle 3 90.
Driving characteristics and
towing tips In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the vertical
coupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements. For trailers with
low driving stability, the use of a
friction-type stabiliser is strongly
recommended.
Do not drive faster than 50 mph, even
in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 20 mph in 1st gear,
or 30 mph in 2nd gear.
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 3 207.
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.
When the trailer load is being
checked, therefore, only the trailer
wheels - and not the jockey wheel -
must be standing on the weighing
apparatus.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %.
148Driving and operating
Remove sealing plug from the hole for
the coupling ball bar and stow it in the load compartment.
Confirm that the colour marking on
the lever is red.
Inserting the coupling ball bar
Insert the coupling ball bar into the
coupling housing and push firmly
downwards until the coupling ball bar
audibly engages. If it does not
engage, repeat fitting procedure.
Do not swing the coupling ball bar to
the left or right, or upwards and
downwards, to avoid disrupting
correct fitting.
Lock coupling ball bar by turning the supplied key in the lock cylinder of the coupling ball bar. Remove key.
Check that the coupling ball bar is
correctly attached:
■ Green marking must be visible on lever.
■ Coupling ball bar must be seated firmly in coupling housing.
Coupling ball bar must be locked and key must be removed.
Driving and operating1499Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
cannot be properly attached, seek the assistance of a workshop.
Eye for break-away stopping cable
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
Dismounting the coupling ball bar
Unlock coupling ball bar and remove
key. Push lever to the left, towards the
coupling ball bar and turn it
downwards. Pull coupling ball bar out of coupling housing.
Remove any rust or dirt from area
around the coupling housing and
coupling ball bar connection before
inserting sealing plug in the hole.
Place the coupling ball bar in the bag supplied, fasten it with the strap and
stow it below the floor cover in the
load compartment.
Do not use steam-jet cleaners or
other high-pressure cleaners to clean
the coupling ball bar.
Trailer stability assist If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While system is working keep steering wheel as still as possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Control 3 137.

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

Tyre pressureCheck the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Use the valve cap key to make
unscrewing the valve caps easier.
The valve cap key is located on the
inside of the tank flap.
Tyre pressure 3 207.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
The tyre pressure tables show all
possible tyre combinations 3 207.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure shall be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring
system The tyre pressure monitoring system
checks the pressure of all four wheels
once per minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure. If
wheels without sensors are mounted,
the tyre pressure monitoring system
is not operational. Retrofitting of
sensors is possible.
Notice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Vehicle care189
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope - or better still a tow
rod - to the front towing eye, never to
the bumper or front suspension units.
Do not tow the vehicle from the rear.
The front towing eye must only be
used for towing and not recovering a
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
Turn key to ignition switch position
ACC and release the electrical
parking brake before towing the
vehicle.Caution
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.
Keep tow rope clear of front bumper, and ensure it is securely fixed to the
towing eye at both ends. Pull on the tow rope to check.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation system 3 115 and
close the windows.
Vehicles with manual transmission:
The vehicle must be towed facing
forwards. The maximum speed is
55 mph. In all other cases, and when
the transmission is defective, the front axle must be raised off the ground.
Vehicles with automatic transmission:
Do not tow the vehicle using the
towing eye. Towing with a tow rope
could cause severe damage to the
transmission. When towing a vehicle
with automatic transmission, use flat
bed or wheel lift equipment.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and replace the spoiler lip. Store
towing eye in the storage
compartment below the floor cover in the load compartment.
