Driving and the environment 186
If you drive with wet brakes, for example after driving through water, after
heavy rainfall or after washing the car, the braking effect will be reduced as
the brake discs will be wet, or possibly frozen (in winter): the brakes must be
“dried” through careful braking.
The brake fluid must be changed every two years at the latest. Heavy use of
the brakes may cause a vapour lock if the brake fluid is left in the system for
too long. This prevents the brakes developing their full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.
•New brake pads must be run in and do not have the correct friction
during the first 200 km. The slightly reduced braking effect can be compen-
sated for by increasing pressure on the brake pedal. This also applies when
new brake pads are fitted.
•If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•When driving downhill, the brakes work hard and get hot very quickly.
Before driving down a long steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the selector lever to a lower gear if
your vehicle has automatic transmission). In this way you will make use of
the engine braking effect and relieve the load on the brakes.
•Never let the brakes “rub” by only applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not work.
•Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.
•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the notes Ÿpage 202 before
buying accessories.
•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gasses purification system
Catalytic converter*
To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not run the fuel tank dry.
– For engine oil changes, do not replenish with too much engine oil
Ÿpage 215, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary
Ÿpage 249.
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 qualified workshop. These symptoms are indicated by the exhaust
gas warning lamp Ÿpage 70. If this happens, unburnt fuel can enter the
exhaust system and escape into the environment. The catalytic converter can
also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!

WARNING
•Please note the safety warnings referring to working in the engine
compartment Ÿpage 209, “Working in the engine compartment”.
•The battery providing assistance must have the same voltage as the flat
battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
•Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
•Keep sparks, flames and lighted cigarettes away from batteries, danger
of explosion. Failure to comply could result in an explosion.
•Observe the instructions provided by the manufacturer of the jump
leads.
•Do not connect the negative cable from the other vehicle directly to the
negative terminal of the flat battery. The gas emitted from the battery could
be ignited by sparks. Danger of explosion.
•Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
•The non-insulated parts of the battery clamps must not be allowed to
touch. The jump lead attached to the positive battery terminal must not
touch metal parts of the vehicle, this can cause a short circuit.
•Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
•Do not bend over the batteries. This could result in chemical burns.
Note
The vehicles must not touch each other, otherwise electricity could flow as
soon as the positive terminals are connected.
Towing and tow-starting
Tow-starting*
The use of jump leads is preferable to tow-starting.
We recommend that you do not tow-start your vehicle. Jump-starting
is preferable Ÿpage 249.
However, if your vehicle has to be tow-started:
– Engage the 2
nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch on the ignition.
– Once both vehicles are moving, 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.
