NoteIf the warning lamp lights up while the vehicle is moving, this indi-
cates a fault in the engine management system. The engine should
be serviced by a qualified workshop without delay.Applies to vehicles: with diesel engineGlow plug system
The indicator lamp lights up to show that the glow plugs
are preheating.Your vehicle is equipped with an automatic glow plug system.
The indicator lamp
lights up while the gl ow plugs are preheating.
If the engine fails to start imme diately, the glow plugs have not
finished preheating. In this case, keep the clutch pedal depressed
(or keep your foot on the brake if your vehicle has an automatic
gearbox) until the engine starts.
Note
•
If the glow plug indicator lamp should start flashing while the
vehicle is moving, this indicates a fault in the engine management
system. The engine should be serviced without delay.
•
If the indicator lamp fails to light up when the ignition is
switched on, this can mean that the glow plug system is defective.
The engine should be serviced.
Electronic stabilisation program (ESP)
This warning lamp monitors the electronic stabilisation
program.The warning lamp
has the following functions:
•
It flashes when the ESP or trac tion control system (ASR) inter-
venes while the vehicle is in motion.
•
The warning lamp will light up continuously if the ESP or the
traction control system (ASR) has been switched off using the ESP
OFF button ⇒page 196 .
•
It lights up when the ignition is switched on and should go out
again after about 2 seconds. This signals that the lamp is working
properly.
•
It will light up continuously if there is a malfunction in the ESP.
•
It will also come on if a fault sh ould occur in the ABS because the
ESP operates in conjunction with the ABS.
If the battery has been disconnected, if the battery voltage is very
low, or if the engine has been started from an outside power source,
the ESP system will perform an init ialisation of the various on-board
sensors while you drive the first few metres. The warning lamp will
light up during this period. It will go out when the initialisation has
been completed.
If the warning lamp lights up and stays on after the engine is
started, this may mean that the control system has temporarily
switched off the ESP. In this case the ESP can be reactivated by
switching the ignition off and then on again. If the warning lamp
goes out, this means the system is fully functional.
For further information on the ESP ⇒page 196 .
Airbag system
This warning lamp monitors the airbag and seat belt
tensioner system.The warning lamp
should light up for a few seconds when the
ignition is switched on.
If the warning lamp does not go out, or if it lights up, flashes or
flickers when the vehicle is moving, this indicates a malfunction in
the system. This is also the case if the warning lamp does not light
up when the ignition is switched on.

Instruments and warning/indicator lamps
18Anti-lock brake system (ABS)
The warning lamp monitors the ABS and the electronic
differential lock (EDL).The warning lamp
lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once the system has run through an automatic test
sequence.
There is a fault in the ABS if:
•
the warning lamp
does not light up when the ignition is
switched on,
•
the warning lamp does not go out again after a few seconds,
•
the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action ). Please take the vehicle to a
qualified workshop as soon as possible. For further information on
the ABS ⇒page 197 .
If a fault occurs in the ABS, the ESP warning lamp will also light up.
Fault in the main brake system
If the ABS warning lamp
lights up together with the brake
warning lamp
⇒ page 31 , this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒ .
If there is a malfunction in the brake system the symbol
will light
up in the instrument cluster. Please refer to ⇒page 31 .
Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS warning lamp .
Please take the vehicle to a qualified workshop as soon as possible.
For further information on the EDL ⇒page 199 .
WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 231, “Working on
components in the engine compartment”.
•
If the brake warning lamp
should light up together with the
ABS warning lamp
, stop the vehicle immediately and check the
brake fluid level in the reservoi r. If the fluid level has dropped
below the "MIN" mark you must no t drive on - otherwise there may
be an increased accident risk. You should obtain professional
assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.
Applies to vehicles: with Audi hold assistAudi hold assist
This warning lamp monitors th e Audi hold assist function.Audi hold assist helps the driver to keep the vehicle stationary while
the engine is running, for instance on steep gradients, at traffic
lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
in the instrument cluster indicates that the func-
tion is activated. You can now ta ke your foot off the brake pedal.
When the vehicle has been stationary for an extended period, Audi
hold assist will automatically apply the parking brake. In this case,
the green symbol will change to red
.

Electro-mechanical parking brake
This warning lamp monitors the electro-mechanical
parking brake.The warning lamp
lights up when the parking brake is applied
with the ignition on. After the ig nition has been switched off the
lamp will stay on for about 30 seconds. The warning lamp will light
up for about 30 seconds if the parking brake is applied with the igni-
tion switched off.
The warning lamp should go out wh en the parking brake is released.
If the warning lamp flashes continuously after the parking brake has
been applied , the brake may not be strong enough to hold the
vehicle on a slope. This may be due to the brakes overheating.
Please note the following points:
•
If the gradient is too steep to park the vehicle safely, the display
will show the message Caution: Vehicle parked too steep .
•
In the event of a fault in the parking brake system the symbol
will also appear in the instrument cluster display together with the
message Parki ng b rake! You should have the fault corrected by a
qualified workshop without delay.
Brake system
The warning lamp flashes if the brake fluid level is too low
or if there is a fault in the ABS system or the parking
brake.If the warning lamp
flashes, there is a fault in the brake system.
The symbol
in the instrument cluster display will flash at the
same time. You can press the button to obtain a message
explaining the fault ⇒page 31 .
If a failure should occur in the ABS, the ABS warning lamp
will
light up together with the brake warning lamp
⇒ .
WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 231, “Working on
components in the engine compartment”.
•
If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident ri sk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could caus e the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Fuel gaugeThe gauge only works when the ignition is switched on.
When the needle reaches the reserve zone, the symbol
lights up
in the instrument cluster display ⇒page 36 together with the
message Please refuel . At this point there are still about 8 litres of
fuel left in the tank. This is your reminder to fill up soon.
The tank capacity of your vehicle is given in the Technical data
section ⇒page 293 .
Caution
Never run the tank completely dry. If there is an irregular fuel supply,
misfiring can occur. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic
converter.

WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 231, “Working on
components in the engine compartment”.
•
If the brake fluid level in the reservoir is too low, this could
result in an accident. Do not drive on. You should obtain profes-
sional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could caus e the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Note
The warning lamp
in the instrument cluster will start flashing as
well if there is a fault in the brake system.
Fault in the cooling system
Faults in the cooling system must be rectified immedi-
ately.If the
symbol flashes in the display, this means that
either the coolant temperature is too high or the coolant

Seats and storage
90If you connect more than one appliance, the total power rating of all
appliances must not exceed 150 W. If necessary, check the type
plates on the connected appliances for details of the power ratings.
Connected appliances must be in perfect condition and free of
defects.
WARNING
•
Heavy appliances or plugs (suc h as power supply units) can
damage the mounting of the 230 Volt Euro socket if they are
suspended directly from the socket – Risk of injury!
•
Make sure that all connected appliances are securely stowed
when driving to prevent them fr om being catapulted through the
car under braking or in an accident – Danger to life!
•
Never spill liquid over the socket – Danger to life! If the socket
does get wet, ensure that it is absolutely dry before using it again.
•
Improper use of the electrical socket or appliances connected
to it can cause injuries or fire – Risk of injury!
•
Never leave children unattended in the vehicle while the engine
is running – Risk of injury!
•
Connected appliances behave differently than when they are
connected to the public electricity grid. As a result, the connected
appliances may become hot during operation – Risk of injury!
•
When using adapters or exten sion cables, please remember
that the child safety device on the 230 Volt Euro socket is deacti-
vated and the socket is live – Risk of injury!
•
Do not insert conductive materi als, such as knitting needles,
into the contacts of the 230 Volt Euro socket – Danger to life!
•
Switch off the connected electrical appliances if the inverter
trips out due to overheat ing – Risk of injury!Caution
•
Please observe the operating instructions for the connected
appliances.
•
If the power drawn by the connected appliances is above 150 W,
the inverter in the socket will get warm. The inverter will trip out if
the temperature exceeds a certain limit. The inverter can trip out on
hot days even when an appliance with a suitable power rating is
used. The inverter will switch on again automatically after it has
cooled down. Appliances which are already connected and
switched on will be activated again automatically ⇒.
•
Do not connect lamps which cont ain a neon tube. For technical
reasons, this may damage the lamp.
•
Do not connect 115 Volt appliances to the 230 Volt Euro socket.
This may cause irreparable damage to the appliance. Check the type
plate on the appliance if you are unsure of the voltage rating.
•
With some power supplies (e.g. on laptop computers), the inte-
grated surge suppressor prevents the equipment from being
switched on because the starting current is too high. If this
happens, please disconnect the power supply unit from the load
and wait for about 10 seconds before re-connecting.Note
•
Unshielded equipment can cause interference on the radio, TV
and vehicle's electrical system.
•
The Euro socket has an integrated child safety device. There is no
power at the socket until the Euro connector is fully inserted.
•
Some appliances may not function normally due to the lower
power rating (wattage).
•
The socket can be operated with 115 Volt power supplies, as is
the case in certain countries. In this case, a different type of inverter
must be installed in the vehicle. Re trofit kits are available from your
Audi dealer. Do not connect 115 Vol t appliances to the 230 Volt Euro
socket.
•
Interference can occur on the radio's AM waveband if electrical
appliances are used near the rear window aerial.

Technical data
braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Note
For safety reasons the parking brake will only release automatically
if the driver's seat belt
is engaged in its buckle.Driving away when towing a trailer
Please note the following po ints to prevent the vehicle
from rolling back unintentionally on a gradient.– Pull and hold the parking brake switch and press the
accelerator. The parking brake will remain engaged and
prevent any tendency to roll back down the slope.
– You can release the parking brake switch as soon as the engine is delivering enough power to the wheels.Depending on the weight of the vehicle and trailer and the steep-
ness of the slope, there may be a tendency to roll back downhill
when driving away from a standstill. You can prevent this by pulling
out the parking brake switch as you press the accelerator (in the
same way as with a conventional handbrake).Emergency braking function
This feature enables you to stop the vehicle if the main
brake system should fail or if the pedal is obstructed.– Pull out and hold the parkin g brake switch to stop the
vehicle with the parking brake in an emergency.
– The brakes will be released immediately if you release the switch or press down the accelerator.
If you pull out and hold the park ing brake switch at a road speed
above about 8 km/h, this will initiate an emergency brake applica-
tion. The brakes are then applied hy draulically at all four wheels.
The effect is the same as an emergency stop (full brake application)
⇒
To prevent the emergency braking function from being used acci-
dentally, a warning buzzer sounds when the switch is operated. The
brakes are released immediately when you release the switch or
press down the accelerator.
WARNING
You should only use the emergency braking function in a real
emergency, for example if the brake system should fail or if the
brake pedal is obstructed. If you use the emergency braking func-
tion by activating the parking brak e switch, the effect is similar to
a full brake application (emergenc y stop). Please remember that
the ESP (with its combined ABS, EDL and traction control func-
tions) is still subject to certain physical limits. In a corner or in bad
road or weather conditions an emergency stop can cause the
vehicle to skid or lose steering control.Driver messages in the instrument cluster displayCaution: Vehicle parked too steep
This message can appear when you apply the parking brake if the
car is parked on a gradient steeper than about 30%.
In this case the parking brake may not be strong enough to prevent
the vehicle from rolling back accidentally.
Please release parking brake
However, please remember that, for safety reasons, the parking
brake will only release automatically if the driver's seat belt is
buckled.

Seat belts
170Seat beltsWhy is it so important to use seat
belts?Seat belts provide effective protection
The common belief that passengers can brace their
weight with their hands in a minor collision is false.It is an established fact that seat belts provide good protection in
accidents. Therefore wearing a seat belt is required by law in most
countries.
Properly worn seat belts hold the occupants in the best position for
maximum protection ⇒fig. 177. The seat belts are capable of
absorbing much of the kinetic energy arising in a collision. Also they
help to prevent uncontrolled movements which could lead to severe
injuries ⇒page 171, “Important safety instructions for using seat
belts”.
If they wear the seat belts correc tly, the passengers benefit greatly
from the ability of the belts to re duce the kinetic energy gradually.
The front crumple zones and other passive safety features (such as
the airbag system) are also designed to absorb the kinetic energy
generated in a collision. Taken together, all these features reduce the forces acting on the occupants and consequently the risk of
injury.
Although these examples are based on
a frontal collision, the phys-
ical principles involved are the same in other types of accidents and
for vehicles with an airbag system. This is why it is so important to
put on the seat belts before every trip – even when “just driving
around the corner”. Ensure that your passengers wear their seat
belts as well ⇒.
Properly worn seat belts have been shown to be an effective means
of reducing the potential for injury and improving the chances of
survival in a serious accident ⇒page 171, “Forces acting in a colli-
sion”.
For information on how children can travel safely in the car
⇒ page 185, “Points to remember if children are travelling in the
car”.
WARNING
•
Seat belts must be put on before ev ery trip – even when driving
in town. This also applies to th e rear passengers (injury risk).
•
During pregnancy, women should always ensure they wear a
seat belt. The best way to protect the unborn child is to protect the
mother ⇒page 174, “Wearing and adjusting the seat belts during
pregnancy”.
