Trailer towing
208If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle and
including the maximum drawbar load.
Elevation values for securing the towing bracket:
65 mm (minimum)
403
629 mm
1112 mm (vehicle with max. load)
from 350 to 420 mm (vehicle with max. load)
1000 mm
Fitting a towing bracket•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•The legal requirements in your country must be observed (e.g. the fitting
of a separate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle’s elec-
trical system. This requires specialised knowledge and tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.WARNING
The towing brackets should be fitted at a specialised workshop.
•If the towing bracket is incorrectly installed, there is serious danger of
accident.•For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•If the power socket is incorrectly installed, this could cause damage to the
vehicle’s electrical system.Note
For the Sport finish, fitting a trailer bracket is not recommended due to the
design of the bumpers.

Vehicle maintenance and cleaningGeneral notesRegular washing and care help maintain the value of your
vehicle.Vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of bodywork corrosion or paint defects.
The best way to protect your vehicle against the harmful effects of the envi-
ronment is through correct maintenance and frequent washing. The longer
substances such as insect remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materials
remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is impor tant to have the
underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
•Car care products can be toxic. Because of this, they must always be
kept closed in their original container. Keep them out of the reach of chil-
dren. Failure to comply could result in poisoning.•Always read and observe the instructions and warnings on the package
before using vehicle care products. Im proper use could cause health prob- lems or damage the vehicle. The use of certain products may produce
noxious vapours; they should be used in well ventilated areas.
•Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and explo-
sion.•Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply the handbrake firmly and remove the key from the
ignition.Caution
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage the
paintwork or the windows of your vehicle. Soak dirt, mud or dust with plenty
of water.
For the sake of the environment
•When purchasing products for your vehicle maintenance, select the ones
which are not harmful to the environment.•The waste from car care products should not be disposed of with ordinar y
household waste. Observe the disposal information on the package.WARNING (continued)

Vehicle maintenance and cleaning
210Vehicle exterior maintenanceAutomatic car wash tunnel
The vehicle can normally be washed without problem in an
automatic car wash.The vehicle paintwork is so durable that the vehicle can normally be washed
without problems in an automatic car wash tunnel. However, the paintwork
wear depends to a large extent on the kind of the car wash tunnel, the
brushes used, its water filtering and the type of cleaning and preservative
products.
Before going through a vehicle wash, be sure to take the usual precautions
such as closing the windows and sunroof.
If the vehicle has special accessories such as spoilers or a roof rack or two-
way radio aerial, etc., it is advisable to consult the car wash tunnel operator.
After washing, the brakes could take some time to respond as the brake discs
and pads could be wet, or even frozen in winter. Dry the brakes by braking
several times.
WARNING
Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Washing by handVehicle washing
– First soften the dirt with plenty of water and rinse it off. – Clean your vehicle from top to bottom with a soft sponge, a glove
or a brush. Use very light pressure.
– Rinse the sponge or glove often with clean water.
– Special car shampoo should only be used for very stubborn dirt.
– Leave the wheels, sill panels etc. until last, using a different sponge or glove.
– Rinse the vehicle thoroughly with water.
– Dry the vehicle surface gently with a chamois leather.
–In cold temperature , dry the rubber seals and their surfaces to
prevent them from freezing. Apply silicone spray to the rubber
seals.
After washing
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times ⇒page 192, “Braking capacity and
braking distance”.
WARNING
•Wash your vehicle with the ignition switched off.•Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.

Caution
•Never remove dirt, mud or dust if the vehicle surface is dry. Never use a
dry cloth or sponge for cleaning purposes. This could scratch the paintwork
or glass on your vehicle.•Washing the vehicle in low temperatures: when washing the vehicle with
a hose, do not direct water into the lock cylinders or the gaps around the
doors, tailgate, or sunroof. Risk of freezing.For the sake of the environment
To protect environment, the vehicle should be washed only in specially
provided wash bays. This prevents toxic, oil-laden waste water entering the
sewerage system. In some places, washing vehicles outside wash bays is
prohibited.
Note
Do not wash the vehicle in direct sunlight.Washing the vehicle with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!– Always observe the instructions for the high-pressure cleaner, particularly those concerning the pressure and the spraying
distance.
– Increase the spraying distance for soft materials and painted
bumpers.
– Do not use a high pressure cleaner to remove ice or snow from windows ⇒page 212. – Never use concentrated jet nozzles (“rotating jets”)
⇒.
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times ⇒page 192.
WARNING
•Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Caution
•Do not use water hotter than 60°C. This could damage the vehicle.•To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This is
also important for bumpers painted in the colour of the bodywork. The closer
the nozzle is to the surface, the greater the wear on the material.Vehicle paint maintenance
Regular waxing protects the paintwork.You need to apply wax to your vehicle if water does not form small drops and
run off the paintwork when it is clean.
Good quality hard wax products are available at your Authorised Service
Centre.
