190Driving and operatingTrailer hitch
General information
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.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt lamp remains or none
remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle when
not in use.Driving characteristics and
towing tips
Before attaching a trailer, lubricatethe 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
and caravan trailers with a permitted
gross vehicle weight of more than
1300 kg the use of a stabiliser is
strongly recommended when driving
above 50 mph.
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 3 253.Trailer towing
Trailer loads
The permissible trailer loads are
vehicle 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 sea
level. 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).

Driving and operating193Attach breakaway stopping cable to
eye.
Check that the coupling ball bar is
correctly installed
● Green marking on rotary knob must point towards green
marking on coupling ball bar.
● There must be no gap between the rotary handle and the
coupling ball bar.
● The coupling ball bar must be firmly engaged in the opening.
● The coupling ball bar must be locked and the key removed.9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Open the protective flap and turn the
key to position c to unlock the
coupling ball bar.
Pull out rotary handle and turn
clockwise as far as it will go. Pull out coupling ball bar downwards.
Insert sealing plug in opening. Fold away socket.
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 is a function of
the Electronic Stability Control 3 160.

After having changed defective fuses,
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.
Instrument panel fuse box
The fuse box is located behind a
cover.
Pull the cover and remove.
Vehicles with power connector:
If the fuse cover has a power
connector, it must be removed by
using an adapter and a screwdriver.
The adapter is stowed in the glovebox 3 65 . The screwdriver is stowed in the
load compartment 3 217.
Attach the adapter to the power
connector.

222Vehicle carewheel and left side rear wheel. Theturn signal light at the current active
position is illuminated until sensor is
matched.
Consult a workshop for service or purchase a relearn tool. There are
two minutes to match the first wheel
position, and five minutes overall to
match all four wheel positions. If it
takes longer, the matching process
stops and must be restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.
3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Midlevel display: Use MENU on the turn signal
lever to select the Vehicle
Information Menu ? in the
Driver Information Centre.

Vehicle care2259Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first gear, reverse gear or P.
The tyre repair kit is on the right side
in the load compartment behind a
cover.
1. Remove the sealant bottle.
2. Insert the thumb into the opening and pull out the compressor.
3. Remove the electrical connection cable and air hose from the
stowage compartments on the
underside of the compressor.
4. Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.

234Vehicle careTowingTowing the vehicle
Insert a screwdriver in the slot at the
lower part of the cap. Release the cap
by carefully moving the screwdriver
downwards.
The towing eye is stowed with the
vehicle tools 3 217.
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 towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on ignition to release steering wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
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.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 50 mph nor further than 60 miles. In all other
cases and when the transmission is
defective, the front axle must be
raised off the ground.
Vehicles with manual transmission
automated: the vehicle must only be
towed facing forwards with the front
axle raised off the ground.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap at the top and engage
downwards.
