CAUTION
● When mixed with other additives the colour of G12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to
do so will result in engine damage!
● If a lot of coolant fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large cool-
ant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage.
Washer fluid and windscreen wiper blades Topping up washer fluid
The water for cleaning the windscreen should always be
mixed with washer fluid.
Fig. 165 In the engine
compartment: Cap of
windscreen washer fluid
reservoir. The windscreen washer and the headlight washers
are supplied with fluid
from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean the windscreen and headlights. We rec-
ommend that you always add a product to the windscreen washer fluid. Ap-
proved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 233.
CAUTION
● Never put radiator anti-freeze or other additives into the windscreen
washer fluid.
● Always use approved windscreen cleansing products diluted as per in-
structions. If you use other washer fluids or soap solutions, the tiny holes in
the fan-shaped nozzles could become blocked.

Wheel change Preparation 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 vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– 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.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. 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 opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.
Changing a wheel
Change the wheel as described below
– Remove the wheel cover . Also refer to ⇒ Fig. 174
– Slacken the wheel bolts .
– Raise the vehicle with the jack at the corresponding area
– Remove the wheel and put on the spare one
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner
– Replace the hub cap.
After changing a wheel
After changing the wheel there are still tasks to complete. – Put the tools and jack back in the luggage compartment.

from the flow of traffic as possible.
– Apply the handbrake firmly.
– Engage first gear , or put the selector lever to position P.
– All occupants should leave the vehicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Check whether a repair is possible using the Tyre Mobility Sys-
tem “General information and safety notes.”
– Unscrew inflation cap from the affected wheel.
– Take the tyre repair kit out of the luggage compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
Take special care if you have to repair a tyre on a slope.
Note
Please observe legal requirements when doing so. Tyre repair
The following sections describe the procedures for repairing

how to use the sealing product.
Inflating the tyre.
– Remove the air compressor and hose from the container.
– Screw the retaining nut onto the valve.
– Plug the compressor cable into a 12 volt power socket.
– Turn on compressor and monitor the pressure shown on the
pressure gauge.
Completing the repair
– Remove the compressor hose from the valve.
– Fit the valve cap.
– Unplug the compressor from the socket.
– Return all tools to their proper storing location.

Bulb change General notes
Before changing any bulb, first turn off the failed component.
Do not touch the glass part of the bulb with your bare hands. The finger-
prints left on the glass will vaporise as a result of the heat generated by the
bulb, causing a reduction in bulb life and condensation on the mirror sur-
face, thus reducing effectiveness.
A bulb must only be replaced by one of the same type. The type is indicated
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle. Main headlights

On this type of headlight, the bulb changes must be made by the Technical Service, given
that complex elements must be removed from the vehicle and a reset must be made on the
automatic control system incorporated.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.

Note
● Depending on weather conditions (cold or wet), the headlights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Due to the difficulty in accessing some of the bulbs, any replacement
work should be done by a Technical Service. However, the following is a de-
scription of how to change the lamps except for the fog lights* and interior
lamps.
