Self-help
260•
Seek professional assistance if th e repair of a tyre puncture is
not possible with the sealing compound.
•
If tyre pressure is less than 1.3 bar after driving about 10
minutes, the tyre is too badly damaged. Do not drive on. You
should obtain professional assistance.Caution
Take special care if you have to repair a tyre on a gradient.
Note
•
Do not use the compressor for longer than 6 minutes at a time,
as it could overheat. When the compressor has cooled down, you
can use it again.
•
If tyre sealant should leak out, leave it to dry and then pull it off
like foil.
•
After carrying out a tyre repair remember to buy a new tyre
sealant can at a qualified workshop. This will ensure that the Tyre
Mobility System is operative again.
•
Please observe the relevant regulations.
Changing a wheelPreparations
Some preparations are necessary before changing a
wheel.– If you have a flat tyre, stop the car well away from moving traffic. Choose a location that is as level as possible.– All passengers should
leave the car. They should wait in
a safe place (for instance behind the roadside crash
barrier).
– Apply the parking brake to stop the vehicle moving acci-
dentally.
–Engage first gear (manual gearbox) or move selector
lever to position P (automatic gearbox).
– When towing a trailer: unhitch the trailer from your vehicle.
– Take the tools ⇒ page 255 and the spare wheel*
⇒ page 256 out of the luggage compartment.
WARNING
If you have a puncture in moving traffic, switch on the hazard
warning lights and place the warning triangle in a visible location.
This is for your own safety and also warns other road users.
Caution
If you have to change the tyre on a gradient, block the wheel oppo-
site the wheel being changed by placing a stone or similar object
under it to prevent the vehicle from rolling away.
Note
Please observe the relevant regulations.How to change a wheel
Change the wheel as described below.–Pull off the hub cap . Also refer to ⇒page 261, “Hub
caps”.

Self-help
268Do not pull too hard with the towi ng vehicle and take care to avoid
jerking the towrope. When towing on a loose surface there is always
a risk of overloading and damaging the anchorage points.
Caution
If there is no oil in the gearbox or no lubricant in the automatic
transmission the car may only be towed with the driven wheels
lifted clear of the road, or transported on a special car transporter
or trailer.
Note
•
Note the regulations concerning towing.
•
The hazard warning lights of bo th vehicles must normally be
switched on. However, observe an y regulations to the contrary.
•
Make sure that the towrope is not twisted, as otherwise the front
towline anchorage on your vehicle could work itself loose.
Front towline anchorage
The front towline anchorage is only mounted if the vehicle
has to be towed.
The screw connection for the towline anchorage is located
behind a cover cap on the right side of the front bumper.
– Take the towline anchorage ou t of the vehicle's tool kit
⇒ page 255 .
– To detach the cover cap from the bumper, firmly press the lower part of the cap inwards to release it ⇒fig. 250.
– Screw the towline anchorage firmly all the way into the screw connection ⇒fig. 251.After use, unscrew the towline anchorage and put it back in the
toolbox. Replace the cap in th e bumper. The towline anchorage
should always be kept in the vehicle.
WARNING
If the towline anchorage is not scre wed in as far as the stop, there
is a risk of the screw connection shearing off during towing (acci-
dent risk).

Self-help

WARNING
There is a high risk of accidents when tow-starting, as the towed
vehicle can easily be driven into the towing vehicle.
Caution
When tow-starting the vehicle, do not tow it further than 50 metres:
otherwise the catalytic converter could be damaged.Towing a vehicle with manual gearbox and front-wheel drive
Towing is relatively straightforward.Please observe the notes ⇒page 267 .
The vehicle can be towed using a towbar or towrope in the normal
way, with all four wheels on the road; it can also be towed with
either the front or rear wheels lifted off the road. The vehicle must
not be towed faster than 50 km/h.Towing a vehicle with automatic gearbox and front-wheel drive
Certain restrictions must be observed when towing your
vehicle.Please observe the notes ⇒page 267 .
The vehicle can be towed with a towbar or towrope in the normal
way, with all four wheels on the ground. When doing so, please note
the following points:•
Release the parking brake ⇒page 121 .
•
Make sure the selector lever is in the N position.
•
The vehicle must not be towed faster than 50 km/h.
•
The vehicle must not be towed further than 50 km. The reason
for this is: when the engine is not running, the gearbox oil pump
does not work and the gearbox is not adequately lubricated for
higher speeds or longer distances.
If the vehicle has to be towed with a breakdown truck, it must only
be suspended at the front wheels. The reason for this is: the drive
shafts are located on the front whee ls. If the car is towed with the
rear wheels lifted off the road (i.e. travelling backwards), the drive
shafts also turn backwards. The planetary gears in the automatic
gearbox then turn at such high speeds that the gearbox will be
severely damaged in a short time.Note
If it is not possible to tow the vehicle as described above, or if it has
to be towed further than 50 km, it must be transported on a special
car transporter or trailer.Towing a vehicle with manual gearbox and four-wheel drive
Certain restrictions must be observed when towing your
vehicle.Please observe the notes ⇒page 267 .
The vehicle can be towed with a towbar or towrope in the normal
way, with all four wheels on the ground. It can also be towed by a
breakdown truck, with the wheels li fted at either the front or rear.
When doing so, please note the following points:•
The vehicle must not be towed faster than 50 km/h.
•
The vehicle must not be towed further than 50 km.

General notes
292General notesExplanation of technical dataWhere not otherwise indicated or separately listed, all technical
data apply to vehicles with st andard equipment for the German
market. Other figures may apply for special versions and export
models.
Please note that the details listed in the vehicle's registration docu-
ments can be taken as correct.
Engine data
The figures for engine power output are determined according to
EU standards.
Performance figures
The performance figures were measured without equipment which
may influence performance, such as mudflaps or extremely wide-
section tyres.
Kerb weight (unladen weight)
These figures (kerb weight according to the currently applicable
version of EU Directive 92/21/EEC) apply to the vehicle with the tank
90% full, with no special equipment. The figures include an addi-
tional 75 kg to allow for the weight of the driver.
When towing a trailer, the gross vehicle weight may be exceeded by
up to 30 kg and the maximum rear axle weight may be exceeded by
up to 80 kg.
Maximum trailer weights
The maximum trailer weights are calculated in accordance with the
currently applicable version of EU Directive 92/21/EEC.
The figures for a trailer with brakes, on gradients up to 8% are appli-
cable only up to a maximum speed of 80 km/h (even though higher
speeds may be permitted when towing a trailer in some countries). The figures for a trailer with brakes on gradients up to 12%
and for
the weight of car and trailer on gradients up to 12% are applicable
up to a maximum speed of 100 km/h. This maximum speed must not
be exceeded even in countries where higher speeds are permitted.
Maximum draw bar loading
The vertical load exerted by the trailer drawbar on the ball joint of
the towing bracket must not exceed 80 kg.
In the interest of safety, we recommend applying the maximum
permitted draw bar weight. The stability of the trailer could be
adversely affected if too little weight is applied.
If the maximum permitted drawbar weight cannot be obtained, e.g.
when using small or light trailers, statutory regulations require that
the drawbar weight be at least 4% of the actual trailer weight (for
single-axle trailers or twin-axle trailers with an axle spacing less
than 1.0 m).
Dimensions1) The height of the vehicle depends on the tyres and suspension.
Take care not to damage low-mounted parts of the car (such as the
spoiler or exhaust system) on steep ramps, uneven road surfaces or
roadside kerbs, etc.Length
