Refilling
The reservoir must always contain a small amount of coolant » .
›
Place a cloth over the cap of the coolant expansion tank and unscrew the cap
carefully.
›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 235.
If the specified coolant is not available, then refilling only with distilled or dem-
ineralised water, and get a specialist garage to correct the water-coolant addi-
tive mix as soon as possible.
CAUTION
■
If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage! Do not drive the vehicle. Switch off the en-
gine and seek assistance from a specialist garage.
■
Do not fill the coolant above the mark
A
» Fig. 235. The coolant could, when
heated, be expelled from the cooling system - risk of damage to the engine
parts.
■
If it is not possible to add coolant, do not continue driving! Switch off the
engine and seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification
can reduce the anti-corrosion effect of the cooling system - risk of damage to
the cooling system and the engine.
■
If non-distilled (non-demineralised) water has been used to top up, the cool-
ant should be replaced by a specialist garage - risk of engine damage.
■
A loss of coolant indicates leaks in the cooling system - risk of engine dam-
age. Top up with coolant and then seek assistance from a specialist garage.
Note
A coolant level which is too low is indicated in the instrument cluster by the
warning light and a corresponding message » page 43. We still recommend
inspecting the coolant level directly at the reservoir from time to time.
Brake fluid
Fig. 236
Brake fluid reservoir
Check the brake fluid under the following conditions.
The vehicle is on a horizontal surface.
The engine is turned off.
Checking the brake fluid level – The brake fluid level must lie between the
markings “MIN” and “MAX”» Fig. 236.
Specification - the brake fluid must comply with the standard VW 501 14 (this
standard meets the requirements of FMVSS 116 DOT4).
The brake fluid change is carried out during the inspection.
WARNING
■
If the date of the brake fluid change is exceeded, steam bubbles could
form in the brake system during heavy braking. This can impair the efficien-
cy of the brakes – risk of accident!
■
The following instructions must be followed at all times when working on
the engine compartment » page 198.
■
If the fluid level drops significantly within a short time or if it drops below
the “MIN” » Fig. 236 mark, this may be an indication of a leak in the brake
system. Stop driving – There is a risk of an accident! Seek help from a
specialist garage.
Note
A brake fluid level which is too low is indicated in the instrument cluster by the
warning light and a corresponding message» page 38. We still recommend
inspecting the brake fluid level in the reservoir from time to time.
