Washer fluid and windscreen wiper bladesWindscreen washer system
Plain water is not sufficient for the windscreen washer 
system.The container for the windscreen washer contains the cleaning fluid for the 
windscreen and the headlight washer system*. The container is located in the 
engine compartment (front left). The filler cap is marked with the symbol 
 W 
⇒ fig. 169 .
The  capacity  of the container is listed in  ⇒page 295.
Plain water on its own is not enough to clean the glass properly. It is therefore 
advisable to add a suitable washer fluid additive (with wax solvent) to the 
water. A washer fluid with freeze-resistant additive should be used in winter.
Caution
•Never put radiator antifreeze or other additives into the windscreen 
washer fluid.•Never use washer fluid which contains paint thinners or solvents as it can 
damage the paintwork.

•To prevent smearing on the windscreen, the wiper blades should be 
cleaned regularly using a window cleaner solution. If the wiper blades are 
very dirty (e.g. insects etc.), they should be cleaned using a sponge or 
cloth. Failure to do so could result in an accident.•For safety reasons, the wiper blades should be changed once or twice a 
year.Caution
•Damaged or dirty windscreen wipers could scratch the windscreen.•Never use fuel, nail varnish remover, paint thinner or similar products to 
clean the windows. This could damage the windscreen wiper blades.•Never move the windscreen wiper or windscreen wiper arm manually. This 
could cause damage.•Do not pull the windscreen wipers forward unless they are in the service 
position. Otherwise the bonnet could be damaged.
Brake fluidChecking the brake fluid level
The brake fluid level can be checked visually.The brake fluid level must be between the “Min” and “Max”  ⇒fig. 172  mark-
ings.
The fluid level may drop  slightly after a period of time due to the automatic 
compensation for brake pad wear. This is quite normal.
H owe ve r,  if  th e  le ve l goes  d own not icea bly i n a   short time, or drops below the 
“Min” mark, there may be a leak in the brake system. If the fluid level in the 
reservoir is too low, this will be indicated by the brake warning lamp 
⇒ page 70 and  ⇒page 77. If this should happen, take the vehicle to a qual-
ified workshop immediately  and have the brake system inspected.

236•A highly explosive mixture of gases is released when the battery is 
under charge. The batteries should be charged in a well-ventilated room 
only.•Keep children away from acid and batteries.•Before working on the electrical system, you must switch off the 
engine, the ignition and all consumers. The negative cable on the battery 
must be disconnected. When a light bulb is changed, you need only switch 
off the light.•Deactivate the anti-theft alarm by unlocking the vehicle before you 
disconnect the battery! The alarm will otherwise be triggered.•When disconnecting the battery from the vehicle electrical system, 
disconnect first the negative cable and then the positive cable.•Switch off all electrical consumers before reconnecting the battery. 
Reconnect first the positive cable and then the negative cable. Never 
reverse the polarity of the connections. This could cause an electrical fire.•Never charge a frozen battery, or one which has thawed. This could 
result in explosions and chemical burns. Always replace a battery which 
has frozen. A flat battery can freeze at temperatures around 0°C.•Ensure that the vent hose is always connected to the battery.•Never use a defective battery. This could cause an explosion. Replace a 
damaged battery immediately.Caution
•Never disconnect the battery if the ignition is switched on or if the engine 
is running. This could damage the electrical system or electronic compo-
nents.•Do not expose the battery to direct sunlight over a long period of time, as 
the intense ultraviolet radiation can damage the battery housing.•If the vehicle is left standing in cold conditions for a long period, protect 
the battery from frost. If it freezes it will be damaged.
Charging the battery
A fully-charged battery is important for reliable starting.– Note the warnings  ⇒ in “Important safety warnings for 
handling a vehicle battery” on page 235 and  ⇒.
– Switch off the ignition and all electrical equipment.
– Only if fast-charging: both battery cables must be disconnected  (first the negative cable, then the positive cable).
– Connect the charger cables to the battery terminals, noting the  colour code (red = positive; black or brown = negative).
– Now connect the battery charger to the power socket and switch  on.
– After charging the battery: switch off the battery charger and  disconnect the power point cable.
– Finally disconnect the charger cables from the battery.
– If necessary, reconnect both battery cables to the battery (first  the positive cable, then the negative cable).When charging with a  low current (for instance with a  small battery charger) 
the battery does not normally have to be disconnected. However, both 
battery cables must be disconnected before  fast-charging the battery with a 
high current. However, always follow the instructions given by the manufac-
turer of the battery charger.
The  fast-charging  procedure for a battery is dangerous  ⇒  in “Important 
safety warnings for handling a vehicle battery” on page 235, as it requires a 
special charger and the corresponding  level of knowledge. We therefore 
recommend that this work should only be performed by a qualified workshop.
