Driving and operating181The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 227.
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 of 60 kg 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.Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
60 kg , the gross vehicle weight rating
must not be exceeded. If the
permissible rear axle load is
exceeded, a maximum speed of
60 mph applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The bag with the coupling ball bar is
stowed on the rear floor cover in the
load compartment.
Place the strap through the rear right
lashing eye, wrap around twice and
tighten the strap to secure the bag.

Driving and operating183Eye for break-away stopping cable
Attach 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.
Swivel the connecting socket
upwards.
Stow the coupling ball bar in the bag
and secure by fixing the strap through the rear right lashing eye. Wrap
around twice and tighten the strap to
secure the bag.

212Vehicle careReplace the used sealant bottle.Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 209.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● Apply the parking brake and engage first gear, reverse gear or
P .
● Remove the spare wheel 3 214.
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
9Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Disengage wheel bolt caps with a
screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.

Vehicle care215Caution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The temporary spare wheel has a
steel rim.
The temporary spare wheel is located in the load compartment beneath the
floor covering.
To remove: 1. Open the floor cover.
2. The temporary spare wheel is secured with a wing nut. Turn
wing nut anticlockwise and
remove the wheel.
There is a box with tools in the
right wall of the load
compartment. Vehicle tools 3 204
3. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
turning right back the wing nut and close the floor cover.
4. After a wheel change back to a full
size wheel, place the spare wheel outside up in the well and secure
with the wing nut.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 208.
Stowing a damaged full size
wheel in the load compartment
The spare wheel well is not designed
for other tyre sizes than the temporary spare wheel. A damaged full size
wheel must be stowed in the loadcompartment and secured with a
strap. Vehicle tools 3 204. To secure
the wheel:
1. Position the wheel outside up close to one sidewall of the load
compartment.
2. Place the loop end of the strap through the front lashing eye on
the appropriate side.
3. Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the lashing eye.

Vehicle care221Glass panelNever clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage
Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas tank must be
removed.
Do not make any modifications to the
liquid gas system.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.
Interior care
Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
