The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann
ot defy the laws of physics. This
should be kept in mind, particular ly on slippery and wet roads and when
towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•
In order to ensure that TCS function correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
•
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation program (ESP)*General notes
The electronic stabilisation program increases the vehicle's
stability on the road.The electronic stabilisation program helps to reduce the danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS. Electronic Stabilising Program (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehi
cle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.

Trailer towingWhat do you need to bear in mind when towing a trailer?Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a
factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. For the after-market fitting of a trailer towing bracket see
⇒ page 188.
Connectors
Your vehicle is fitted with a 12-pin co nnector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available from any Technical Service.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. If you do not load the trailer up to
the maximum permitted trailer weight , you can then climb correspondingly
steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1,000 m above sea level. With increasing altitude the engine power and
therefore the vehicle's climbing ability are impaired because of the reduced
air density. The maximum trailer weight has to be reduced accordingly. The weight of the vehicle and trailer combination must be reduced by 10% for
every further 1,000 m (or part thereof).
The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
Where possible, operate the trailer with the maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
The figures for trailer weights and draw bar weights that are given on the
data plate of the towing bracket are for certification purposes only. The
correct figures for your specific model, which may be lower than these figures
for the towing bracket, are given in the registration documents ⇒Section
“Technical data”.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.

Note•
Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
•
Find out whether special regulations apply to towing a trailer in your
country.
Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with in structions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•
By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will prevent the jerking that can be
caused by the trailer wheels locking. Sele ct a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle.
Heating
When climbing long hills in hot weather with the engine running fast in a low
gear, you should monitor the coolant temperature gauge ⇒page 55.
Electronic Stabilisation Program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.

Fitting a towing bracket
•
Driving with a trailer implies additional work for the vehicle. For this
reason, before fitting a trailer system, refe r to the Technical Service to find out
if the vehicle cooling system should be adjusted.
•
Observe the legal requirements in yo ur country (e.g. the fitting of a sepa-
rate warning lamp).
•
Certain vehicle componen ts, e.g. the rear bumper must be removed and
reinstalled. The towing bracket securi ng bolts must be tightened using a
torque wrench, and an electrical sock et must be used to connect to the
vehicle's electrical system. This requires specialist knowledge and tools.
•
The figures in the illustration show the dimensions and attachment points
which must be observed if you are retrofitting a towing bracket.
WARNING
Towing brackets should be fitted by specialists.
•
If the towing bracket is incorrectly installed, there is serious danger of
an accident.
•
For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•
If the electrical socket is incorrectly installed, this could cause damage to
the vehicle's electrical system.

Wheel changePreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the vehicle as far away from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the vehicle. They should wait in a safe area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
–Apply the handbrake firmly.
–Engage the first gear, or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
–Take the vehicle tools and the spare wheel out of the luggage
compartment.

Towing and tow-startingTo w - s t a r t i n g *
The use of jump leads is preferable to tow-starting.We recommend that you do not tow-start your vehicle. Jump-starting
is preferable ⇒page 240.
However, if your vehicle has to be tow-started:
–Engage the 2
nd or the 3
rd gear.
– Keep the clutch pressed down.
– Switch on the ignition.
– Once both vehicles are mo ving, release the clutch.
– As soon as the engine starts, press the clutch and move the gear lever into neutral. This helps to prevent driving into the towing
vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
Caution
When tow-starting, fuel could enter the catalytic converter and damage it.
Towing eyesPlease observe the following points if you use a tow-rope:

Notes for the driver of the towing vehicle
– Drive slowly at first until the to w-rope is taut. Then accelerate
gradually.
– Begin and change gears cautiously. If you are driving an auto- matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not working in the vehicle you are towing. Brake earlier than you
would normally, but with a more gentle pressure on the brake.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.
Fitting the towing eye
– Take the towing ring and the wheel spanner out of the vehicle tool kit.
– Pull the lower front cover down and leave the cover hanging on the vehicle.
– Remove the cover of the screw hole, insert a screwdriver into the lower slot and lever gently.
– Screw the towing eye as shown by arrow anti-clockwise to the
limit position in the front ⇒page 243, fig. 173 or rear
⇒ page 243, fig. 174 threaded hole.
– Use the wrench for leverage to tighten the towing eye.Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar. A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, espec
ially when using a tow-rope. Both
drivers should be familiar with the te chnique required for towing. Inexperi-
enced drivers should not attempt to tow-start or tow away another vehicle.
Do not pull too hard with the towing vehicle and take care to avoid jerking the
tow-rope. When towing on an unpaved road, there is always a risk of over-
loading and damaging the anchorage points.
The ignition of the vehicle being towed must be switched on to prevent the
steering wheel from locking and also to allow the use of the turn signals,
horn, windscreen wipers and washers.
As the brake servo does not work if the engine is not running, you must apply
considerably more pressure to the brake pedal than you normally would.
As the power assisted steering does not work if the engine is not running, you
will need more strength to steer than you normally would.
Towing vehicles with an automatic gearbox
•
Put the selector lever into position “N”.
•
Do not drive faster than 50 km/h when towing a vehicle.
•
Do not tow further than 50 km.
•
If a breakdown vehicle is used, the vehicle must be towed with the front
wheels raised.Note
•
Observe legal requirements when towing or tow-starting.
