switching on the ignition.
CNG quality
Whenever you refuel the quality of
the natural gas is automatically veri-
fied and is displayed when the igni-
tion is switched on. The display is
made in a percentage of between
70% and 100%. The greater the per-
centage displayed the lower the con-
sumption may be.
Average

The average speed will be shown af-
ter a distance of about 100 metres
has been travelled. Otherwise hori-

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 %, 52

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

the warning lamps.
● Depending on the equipment, some set-

and instructions can also be carried out
in the Easy Connect system.
● When several warnings are active at the
same time, the symbol

sively for a few seconds and will stay on until
the fault is rectified. Odometer

If on
ly

the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard.
Normal temperature
If in normal 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 250. 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*

Operation
●
Addition a
l 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 cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

very low, the lower diode flashes in red. The yellow control lamp 
lights up when the
re
serve level has been reached.
The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode.
The green warning lamp  switches off when
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.

Operation
● The air c onditioner c
ompr
essor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner chec
ked by a specialised work-
shop. Special Characteristics
If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air c onditioner c

ould mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air outlets

s

ure proper heating, cooling and venti-
lation in the vehicle interior, air vents
››› Fig. 184 1 should remain open.
● Turn the corresponding thumbwheel (de-
t ai
l) in the r

equired direction to open and
close the air vents. When the thumbwheel is in the  position, the corresponding air vent
is

closed.
● Change the air direction using the ventila-
tion grill
e lever.
There are other additional, non-adjustable air
vents in the dash panel 2 , in the footwell
and in the r e
ar ar

ea of the interior. Note
Food, medicine and other heat or cold sensi-
tive o b

jects should never be placed in front of
the air outlets as they may be damaged or
made unsuitable for use by the air coming
from the air vents. 162

Diesel engines can take a few seconds longer
than usual to start on cold days. Therefore
the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must re-
main pressed until the engine starts up. Dur-
ing preheating, the warning lamp  remains
lit.
The preheating time depends on the coolant
and exterior temperatures. With the engine at
operating temperature, or at outside temper-
atures above +8°C, the warning lamp  will light up for about one second. This means
that the en

gine starts immediately.
If the engine does not immediately start up,
interrupt the starting process and try again
after 30 seconds. To start the engine again,
return the key to position 1 .
