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-

orks when the ignition is
switched on. In order to avoid engine dam-
age, please read the following notes for the
different temperature ranges. Engine cold
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

when the ignition is switched on. When the
display reaches the reserve mark, the lower
diode lights up in red and the control lamp 
appears ››› page 104. When the fuel level is
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

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 .

WARNING
● Never ru n the en
gine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
extr eme lo

ad conditions until the engine has
reached its normal operating temperature,
otherwise this can damage the engine. For the sake of the environment
Do not warm up the engine by idling it. You
shoul d driv

e off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it i

s difficult to turn the ignition key to
the position 1 , turn the steering wheel to
both side s
to release the steering lock.
● When starting from cold, the engine may be
a little noisy
for the first few seconds until oil
pressure has built up in the hydraulic valve
lifters. This is quite normal, and no cause for
concern.
● If the vehicle battery is disconnected and
reconnect
ed, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up.
● Vehic

les with automatic gearbox: after
switc
hing off the ignition, you can only re-
move the ignition key if the selector lever is in position “P” (parking lock). Next, the se-
lect

ossible vehicle theft is prevented with the
steering lock engaged. WARNING
● Never sw it

ch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury. ●
Never r emo

ve the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could suddenly lock, making it impossible
to steer the vehicle: risk of accident!
● Always take the key with you when you
leav
e the vehicle. This is particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
loa d f

or a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
● Aft er the en

gine is switched off the radiator
fan may run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation.
● If the vehicle is stopped and the Start-Stop
syst
em* switches off the engine, the ignition » 165

the warning lamp switches off, you can con- tinue driving in a normal manner.
 Gearbox: press the brake and
engage a gear again.
If the fault was caused by a gearbox with a
high temperature, this driver message will be
displayed when the gearbox has cooled
again.
Run-in and economical driving Runnin
g-in the engine A new vehicle should be run in over a dis-
t
anc
e of

1500 km (1000 miles). For the first
1,000 km the engine speed should not ex-
ceed 2/3 of the maximum permissible engine
speed. In doing so, do not accelerate at full
throttle and do not drive with a trailer! From
1000 to 1500 km (600 to 1000 miles) you
can gradually increase the engine rpm and
road speed.
During its first few hours of running, the in-
ternal friction in the engine is greater than
later on when all the moving parts have bed-
ded down. How the vehicle is driven for the first 1,500
km influences

the future engine perform-
ance. Subsequently, also drive at a moderate
rate, especially when the engine is still cold:
this will lead to less engine wear and tear
and will prolong its useful life.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs “smoothly”.
If the engine revs too much, cut fuel injection
to protect the engine.
Environmental compatibility Environmental protection is a top priority in
the de
