WARNING

If the warning lamps are ignored, the vehicle
may stall in traffic, or may cause accidents
and severe injuries.

●

Never ignore the warning lamps.

●

Stop the vehicle safely as soon as possible.

●

Park the vehicle away from traffic and en-

sure that there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).

●

A faulty vehicle represents a risk of acci-

dent for the driver and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.

●

Before opening the bonnet, switch off the

engine and allow it to cool.

●

In any vehicle, the engine compartment is a

hazardous area and could cause severe inju-
ries

Coolant

Fig. 42

Engine compartment: coolant expan-

The coolant tank is located in the engine

When the engine is cold, replace the coolant
when the level is below .

Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive

G13

(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25 °C
(-13 °F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant.

To protect the cooling system, the percentage
of additive must always be at least 40 %,

even in warm climates where anti-freeze pro-
tection is not required.

If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.

When the coolant is topped up, use a mixture
of

distilled water and at least 40 % of the

G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection

›››

in Checking the

coolant level and topping up on page 194

The mixture of G13 with G12 plus (TL-VW 774
F), G12 (red) or G11 (green-blue) engine cool-
ants will significantly reduce anti-corrosion
protection and should therefore be avoided
