Data summary
MenuFunction
Current fuel
consumption
The current fuel consumption dis-
play operates throughout the jour-
ney, in litres/100 km; and with the
engine running and the vehicle
stopped, in litres/hour.
Average fuel consumption a)
After turning on the ignition, aver-
age fuel consumption in li-
tres/100 km will be displayed after
travelling about 100 metres. Other-
wise horizontal lines are displayed.
The value shown is updated approxi-
mately every 5 seconds.
ACT®
*: Depending on the equip-
ment, number of active cylinders.
Operating range a)
Approximate distance in km that can
still be travelled with the fuel re-
maining in the tank, assuming the
same style of driving is maintained.
This is calculated using the current
fuel consumption.
Travelling
timeThis indicates the hours (h) and mi-
nutes (min) since the ignition was
switched on.
MenuFunction

made in a percentage of between
70% and 100%. The greater the per-
centage displayed the lower the con-
sumption may be.
Average

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. 60

The essentials
To protect the cooling system, the percentage
of a
d
ditive 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 Topping up cool-
ant on p ag
e 275

. 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

Observe the safety warnings ›››
in Warning
and contr o
l lamps on page 119. WARNING
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.
● The outside temperature sensor takes a
guideline meas
urement. Note
● Differ ent

versions of the instrument panel
are available and therefore the versions and instructions on the display may vary. In the
ca
se 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 several warnings are active at the
same time, the symbol
s are shown succes-
sively for a few seconds and will stay on until
the fault is rectified. Odometer

Operation
For vehicles with no coolant temperature
g aug
e, a c
ontrol lamp  appears for high
coolant temperatures ››› page 274. Please
note ››› .
The c oo
l

ant temperature gauge only works
when the ignition is switched on ››› Fig. 124.
In order to avoid engine damage, please read
the following notes for the different tempera-
ture ranges.
Engine cold
If only 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
temperat

ure is excessive ››› page 274. 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 43 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 cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Petrol/Diesel

the lower diode flashes in red.
The fuel range is displayed on the instrument
panel ››› Fig. 122 3 .
The c ap
ac

ity of the fuel tank of your vehicle is
given in the Technical data section
›››  page 58. CAUTION
Never run the fuel tank completely dry. An ir-
re gu

lar fuel supply could cause misfiring. In
this way the unburned fuel can reach the ex-
haust system, which could cause the catalytic
converter to overheat resulting in damage. 118
