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.

The average speed will be shown af-
ter a distance of about 100 metres
has been travelled. Otherwise hori-
zontal lines are displayed. The value
shown is updated approximately ev-

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-

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11

Even though outside temperatures are above
freez in

g, some roads and bridges may be icy.
● At outside temperatures above +4°C
(+39°F), even when the “ice c
rystal symbol”
is not visible, there may still be patches of ice
on the road.
● Do not rely on the outside temperature in-
dicator! Note
● Differ ent

versions of the instrument panel
are available and therefore the versions and
instructions on the display may vary. In the
case of displays without warning or informa-
tion texts, faults are indicated exclusively by
the warning lamps.
● Depending on the equipment, some set-
tings
and instructions can also be carried out
in the Easy Connect system. ●
When sever a

l warnings are active at the
same time, the symbols are shown succes-
sively for a few seconds and will stay on until
the fault is rectified. Odometer

Odometer/trip recorder
The odometer shows the total distance cov-
ered by the vehicle.
The trip recorder shows the distance that has
been travelled since it was last reset. It is used to measure short trips. The last digit of
the trip recor

metres or tenths of a mile.
The trip recorder can be set to zero by press-

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

hes 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.

The interior cooling system only works when

The air conditioner operates most effectively
with the windows and the panoramic sliding
sunroof closed. However, if the vehicle has
heated up after standing in the sun for some
time, the air inside can be cooled more quick-
ly by opening the windows and the panoram-
ic sliding sunroof briefly.
Climatronic: change the temperature unit on
the screen of the radio or on the factory-fit-
ted navigation system
Changing the temperature display from Cel-
sius to Fahrenheit on radio or on the factory-
fitted navigation system is done using the
menu on the instrument panel
›››  page 30. The cooling system cannot be activated
If the air conditionin

g system cannot be
switched on, this may be caused by the fol-
lowing:
● The engine is not running.
● The fan is switched off.
● The air conditioner fuse has blown.
● The outside temperature is lower than ap-
prox
imately +3°C (+38°F).
● The air conditioner compressor has been
temporari
ly 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 temperature 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. 165
