Driving and the environment
WARNING (Continued)
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 226, Technical modifi-
cations.
● If a brake system circuit fails, the braking distance will be increased
considerably. Contact a specialised workshop immediately and avoid un-
necessary journeys.

Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank. –
For engine oil changes, do not replenish with too much engine
oil ⇒ page 241, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 287.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 76. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Risk of fire!
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. 

Refuelling
Fig. 159 Tank flap open
The tank flap is released manually and is located at the rear of the
vehicle on the right.
The tank holds approximately 55 litres. For all-wheel drive vehicles,
the tank capacity is approximately 60 litres.
Vehicles that work with LPG have two fuel tanks: one for LPG and
one for petrol ⇒ page 230.
Opening the fuel tank cap
– Lift the lid.
– Hold the cap firmly with one hand, then insert the key into the
lock and rotate 180° to the left. –
Unscrew the cap, turning it anticlockwise.
Closing the fuel tank cap
– Screw the tank cap to the right, until the point of feeling a
“click”.
– Turn the key in the lock, without releasing the cap, clockwise
through 180°.
– Remove the key and close the flap until it clicks into place. The
tank cap is secured with an anti-loss attachment
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the fuel tank is “full”. Never attempt to fill beyond this point, as this
will fill the expansion chamber. Fuel may leak out if ambient conditions are
warm.
The correct fuel grade for your vehicle is given on a sticker on the inside of
the fuel tank flap. Here you will find further information on fuel. 

Fig. 161 LPG tank in
spare wheel well Before refuelling, turn off the engine and switch off the ignition and mobile
telephone ⇒ 
.
Read the instructions on how to use the LPG pump carefully.
Opening the fuel tank cap
The LPG filler neck is behind the fuel cap, next to the petrol filler neck.
● The tank flap is located on the rear right hand side of the vehicle.
● Open the fuel tank flap.
Refuelling
● Remove the plug from the gas filler mouth ⇒ Fig. 160 1
.
● Screw the required adapter 2 on the LPG gas filler neck.
● Refuel as indicated in the pump instructions.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, release the button on the
pump to stop the flow.
Closing the fuel tank cap
● Unscrew the adapter of the gas filler neck 2
.
● Screw the cap onto the gas filler neck 1.
● Close the fuel tank flap. The tap should be flush with the bodywork.
WARNING
Incorrect handling of LPG can cause explosions, fire, serious burns and
other injuries.
● LPG is a highly explosive and inflammable substance.
● Small quantities of LPG may leak out after refuelling. If LPG comes in-
to contact with the skin there is a risk of freezing. 
