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 %, » 51

The essentials
even in warm climates where anti-freeze pro-
t ection i
s
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 Topping up cool-
ant on p ag

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significant-
ly reduce anti-corrosion protection and
should therefore be avoided ››› in Topping

Operation
Normal temperature
If in norm
al
operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 266. CAUTION
● To en s

ure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
›››  page 35 as a guide.
● Additional lights and other accessories in
front of
the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the c
ooling air when the vehicle is moving. If the spoiler is damaged this can re-
duce the c
oo

ling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

The yellow control lamp  lights up when the

The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode. The green warning lamp  switc

the natural gas is exhausted. The engine
changes to operate with petrol.
Problem: If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.
