The gross combination weight is the actual weight of the laden vehicle plus
the actual weight of the laden trailer . If the maximum permissible trailer
weight is to be utilized, the weight of the vehicle may have to be reduced.
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 permitted pressure shown on the sticker on
the inside of the tank flap. Set the tyre pressure of the trailer tyres in accord-
ance 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.
Headlight adjustment
If towing a trailer the dipped light may dazzle other drivers. Use the headlight
range control to lower the cone of light. If you do not have headlight range
control, have the headlights adjusted by a qualified dealership.
WARNING
•Never transport people in a trailer. This could result in fatal accidents.
•To avoid dazzling other drivers, adjust the dipped beam according to
the load. If not, an accident may occur.
•If using 225/45 R 17 94 W tyres for 7J x 17 wheels it is not permitted to
tow a trailer.
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.

Cleaning and caring for your vehicle 196
Polishing the paintwork
Polishing brings back gloss to the paintwork.
Polishing is only necessary if the paint has lost its shine, and the gloss cannot
be brought back by applying wax. Polish can be obtained from your Author-
ised Service Centre.
The car must be waxed after polishing if the polish used does not contain wax
compounds to seal the paint Ÿpage 195, “Waxing the car”.
Caution
To prevent damage to the paintwork:
•Do not use polishes and hard wax on painted parts with a matt finish or
on plastic parts.
•Do not polish your vehicle in a sandy or dusty environment.
Caring for plastic parts
Solvents will damage plastic parts.
If normal washing fails to clean plastic parts, clean them with special solvent-
free plastic cleaning and care products.
Caution
•The use of liquid air conditioners directly over the air vents of the vehicle
may damage the plastic parts if the liquid is accidentally spilled.
•Cleaning products which contain solvents will damage the material.
Cleaning windows and exterior mirrors
Cleaning the windows
– Moisten the windows with commercially available, alcohol based
glass cleaner.
– Dry the windows with a clean chamois leather or a lint-free cloth.
Removing snow
– Use a small brush to remove snow from the windows and mirrors.
Removing ice
– Use a de-icer spray.
Use a clean cloth or chamois leather to dry the windows. Chamois leathers
which have been used on painted surfaces are not suitable for use on
windows. They will be soiled with wax deposits which would smear the
windows.
If possible use a de-icing spray to remove ice. If you use an ice scraper, push
it in one direction only. Do not move it to and fro.
Use window cleaner or a silicone remover to clean off rubber, oil, grease and
silicone deposits.
Wax deposits have to be removed with a special cleaner which is available
from your Authorised Service Centre. Wax deposits on the windscreen could
cause the wiper blades to judder. A window cleanser specifically for removing
wax will stop the blades juddering if added to the windscreen washer fluid.
Grease removing cleansers will not remove wax deposits.
Caution
•Never use warm or hot water to remove snow and ice from windows and
mirrors. This could cause the glass to crack!
