Coolant temperature gauge
The coolant temperature gauger=> page 10,
Fig. 3@ only works when the ignition is switched
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
The LEDs will settle somewhere in the centre of
the display once the engine has reached operat­
ing temperature. If the warning lamp. lights
up on the infotainment display, the coolant tem­
perature is too high r=> page 14.
10 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
assista nee.
i 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, a red LED will light up and the indicator
lamp I]] will appear r=> page 18. The LED will
flash in red if the fuel level is very low.

The tank capacity of your vehicle is given in the
Technical data section ¢ page 288.
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 ¢ page 20.
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.
Overview
When you switch on the ignition, some of the
warning and indicator lamps light up briefly to
show that the associated systems are working
properly. These systems are marked with a../ in
the following tables. If one of these warning/in­
dicator lamps does not light up, there is a fault in
the associated system.

Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ESC) increa­
ses the car's stability. It reduces the tendency to
skid and improves the stability and road holding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and
wheelspin on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc­
ing the engine torque. The indicator lamp DJ in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual
standstill. You can continue to steer the vehicle
even when the brakes are on full. Keep your foot
on 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).
0 This
function is not available at high speeds.
� To
prevent the disc brake of the braked wheel
8 from
overheating, the EDL cuts out automatically
"

technology
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
the ESC.
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

Emission control
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­
rol, otherwise the catalytic converter will be ir­
reparably 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 diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean-
244 ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the symbol
C for the diesel particulate filter lights up
¢page 17.
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, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) -risk of fire!
- Do not apply any underseal 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 .
A WARNING
- Switch off the engine.
- Switch off the ignition.
- Apply the parking brake.
- Put the gear lever in neutral or selector in P.
- Wait for the engine to cool down.
- Keep children away from engine compart-
ment.

Downloaded from www.Manualslib.com manuals search engine Checking
and topping up fluids
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
system -risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­
tance.

250 Checking
brake fluid level
� Read off the brake fluid level on the brake fluid
reservoir ¢page 246, Fig. 214. The brake fluid
level must be between the MIN and MAX marks
¢_A.
The brake fluid level is also automatically moni­
tored.
Having brake fluid changed
Have the brake fluid changed regularly by a quali­
fied workshop.
A WARNING
- If the brake fluid level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired -risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!
CD CAUTION
- If the brake fluid level is above the MAX
mark, brake fluid may escape via the cap on
the reservoir in certain circumstances and
cause damage to the vehicle.
- Brake fluid must not be allowed to come in­
to contact with the vehicle's body, other­
wise it will attack the paintwork.
Battery General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by a qualified
workshop ¢ ,& .
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
