on. In order to avoid possible damage to the en­
gine, please read the following notes for the dif­
ferent temperature ranges.
Engine cold
If the LEDs are still in the left-hand range of the
display, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine
loads.
Normal temperature
In normal operation the LEDs will settle some­
where in the centre of the dis play once the en­
gine has reached operating temperature. The
LEDs may also extend further into the right-hand
range of the display when the engine is working

play and the warning lamp.
appears in the dis­
play, the coolant temperature is too high
¢page 12.
CD CAUTION
- Additional lights and other accessories in
front of the air inlet reduce the cooling ef­
fect of the radiator. At high outside temper­
atures and high engine loads, there is a risk
of the engine overheating.
- The front spoiler also ensures proper distri­
bution of the cooling air when the vehicle is
moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Obtain professional
assistance.
� Note
Diesel engines are so efficient that they may
not reach their full operating temperature in
very cold weather. This is quite normal and no
cause for concern.

Fuel gauge
The gauge @ only works when the ignition is
switched on. If there is less than 7 litres of fuel in
the tank, the LED at the bottom of the dial will
light up in red and the indicator lamp tD will ap­
pear c:::>page 16. The LED at the bottom of the
dial will flash in red if the fuel level is very low.
The tank capacity of your vehicle is given in the
Technical data section c:::> page 258.
CD CAUTION
Never run the tank completely dry. If there is
an irregular fuel supply, misfiring can occur.
Unburnt fuel can then enter the exhaust sys­
tem. This can lead to overheating and dam­
age to the catalytic converter.
Warning and indicator
lamps
Description
The warning and indicator lamps light up or flash
in the instrument cluster. Their purpose is to in­
dicate functions or faults.
Some of the warning and indicator lamps may be
accompanied by a driver message and a warning
tone. The warning/indicator lamps and driver
messages on the display can be masked by fur­
ther displays. To display a warning or message
again, use the controls on the multi-function
steering wheel to select the display tab for warn­
ing/indicator lamps and messages c:::> page 18.
If several malfunctions have occurred, you can
use the thumbwheel to scroll through them on
the display.
Some of the warning lamps may be displayed in
different colours.

the coolant level¢ page 224.
- If the coolant level is too low, add more coolant
¢ page 225. Do not drive on until the warning
lamp has gone out.
- If the coolant level is correct, the overheating
may be caused by a malfunction of the radiator
fan. Do not drive on. Obtain professional assis­
tance.

run with vehicle stationary
Let the engine cool down by running it at idling
speed for a few minutes.
A WARNING
- Never open the bonnet if you can see or hear
steam or coolant escaping from the engine
compartment; there is a risk of being scal­
ded. Wait until you can no longer see or
hear escaping steam or coolant.
- The engine compartment of any motor vehi­
cle is a dangerous place. Before carrying out
any work in the engine compartment,
switch off the engine and allow it to cool
down. Please observe the important safety
warnings ¢ page 220, Working on compo­
nents in the engine compartment.

WARNING
- Always adapt your driving style to the traffic
conditions.
- Only use the launch control programme
when road and traffic conditions permit,
and make sure your manner of driving and
accelerating the vehicle does not inconven­
ience or endanger other road users.
- Please note that the driven wheels may
start to spin when the sport mode is switch­
ed on, causing the vehicle to lose grip, in
particular on slippery or wet roads -danger
of skidding!
- When acceleration has been completed, you
should deactivate the sport mode again by
briefly pressing
the I� OFF! button.
ij)) Note
- The gearbox may be hot after you have used
the launch control programme. In this case,
the programme may not be available for
several minutes. The programme will be
available again after a cool-down period.
- Accelerating with the launch control pro­
gramme places a heavy load on all parts of
the vehicle. This can result in increased wear
and tear.
Back-up programme
Applies to vehicles: with S tronic gearbox
A back-up programme is in place should a fault
occur in the control system.
If all selector lever positions are highlighted in
the infotainment display, a system malfunction
has occurred. In this case, the S tronic gearbox
will switch to a backup programme. The vehicle
can still be driven in the backup programme,
however only at reduced speed and not in all
gears. In certain cases, you may not be able to se­
lect reverse gear.
CD CAUTION
If the gearbox switches to the back-up pro­
gramme, drive to a qualified workshop with­
out delay and have the fault rectified . Automatic

the brake pedal and do not pump the brakes.
You will feel the brake pedal pulsate while the
anti-lock brake system is working.
Brake assist system
The brake assist system can shorten the braking
distance. The braking force is automatically boos­
ted if you press the brake pedal quickly in an
emergency. You must keep pressing the brake
pedal until the danger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match the
amount of grip available. This helps the car to
start moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the
spinning wheel and directs the power to the oth­
er driven wheel (or wheels on quattro* versions).
This function is not available at high speeds.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automatically
if subjected to excessive loads. The vehicle can
still be driven. The EDL will switch on again auto­
matically when the brake has cooled down.
Steering recommendation
The ESC helps to stabilise the vehicle by changing
the steering wheel torque.
Selective wheel torque control
Selective wheel torque control intervenes when
cornering by braking the wheel(s) on the inside of
the bend individually as required. This enables
precision cornering. The relevant system may not
intervene in the wet or snow.
Multicollision brake assist system
The "multicollision brake assist system" can help
to reduce the risk of skidding and further colli­
sions during an accident. If the airbag control
unit detects that a collision has taken place up-
� wards
of a certain speed, the vehicle is braked by
a'.: the ESC.

technology
The vehicle will not be braked automatically if:
- the driver presses the accelerator,
- the brake pressure applied by pressing the
brake pedal is higher than the brake pressure
initiated by the system,
- or the ESC, the brake system or the vehicle's
electrical system are not fully functional.
A WARNING
- The grip provided by the ESC and the inte­
grated systems is still subject to the physi­
cal limits of adhesion. Always bear this in
mind, especially on wet or slippery roads. If
you notice the systems cutting in, you
should reduce your speed immediately to
suit the road and traffic conditions. Do not
let the extra safety provided tempt you into
taking any risks when driving -this can
cause accidents.
- Remember that the accident risk always in­
creases if you drive fast, especially in cor­
ners or on a wet or slippery road, or if you
follow too close behind the vehicle in front
of you. Please bear in mind that even the
ESC and the integrated systems cannot
compe nsate for the increased accident risk.
- When accelerating on a uniformly slippery
surface (for instance all four wheels on ice
or snow), press the accelerator gradually
and carefully. The driven wheels may other­
wise start to spin (in spite of the integrated
control systems), which would impair the
car's stability and could lead to an accident.
{D Note
- To ensure that the ABS and ASR systems
work properly, all four wheels must be fit­
ted with identical tyres. Any differences in
the rolling radius of the tyres can cause the
system to reduce engine power when this is
not desired.
- The systems can make noises when they in­
tervene.
- If the indicator lamp DJ orr§J appears,
there may be a malfunction ¢ page 14. -

Em ission control
systems
Catalytic converter
Applies to vehicles with petrol engine: The vehi­
cle must only be used with unleaded petrol; oth­
erwise the catalytic converter will be irreparably
damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­
ing. This allows unburnt fuel to enter the exhaust
system, which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: The die­
sel particulate filter can filter out almost all soot
particles contained in the exhaust gas. In normal
driving conditions the filter is self-cleaning.
Should the self-cleaning function of the filter not
be able to operate, e.g. when the vehicle is con­
tinuously used only for short trips, the filter be-
220 comes
obstructed with soot and the symbol Cl
for the diesel particulate filter lights up
¢page 15.
A WARNING
The exhaust system is very hot when the vehi­
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission control system (cata­
lytic converter or diesel particulate filter),
do not park the vehicle where the exhaust
can come into contact with flammable ma­
terials under the car (e.g. on grass or at the
forest edge) -risk of fire!
- Do not apply any undersea[ agents in the
area around the exhaust system -risk of
fire!
Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area ¢ .,&.
A WARNING
- Switch off the engine.
- Switch off the ignition.
- Apply the parking brake.
- Pu t the gear lever in neutral or selector in P.
- Wait for the engine to cool down.
- Keep children away from engine compart-
ment.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.
Topping up coolant
Fig. 214 Engine compartment: Cap of coolant expansion
tank
Checking coolant level
.. Park
your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan­
sion tank ¢ page 222, Fig. 211. When the en­
gine is cold, the coolant level should be be­
tween the marks. When the engine is warm, it
may be slightly above the top mark. Checking
and topping up fluids
Topping up coolant
Impor tant: The coolant expansion tank must not
be empty ¢(D.
.. Wait for the engine to cool down.
.. Cover the cap on the expansion tank with a
cloth, and carefully unscrew the cap anti-clock­
wise ¢ .&_ .
.. Add coolant in the correct concentration
¢ page 224 up to the top mark.
.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys­
tem -risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .
