12Warning symbol in instrument cluster

If the symbol
 lights up in the display, this means that either the
coolant temperature is too high or the coolant level is too low
⇒ page 33 .
If the needle is at the top end of the dial, this means the coolant
temperature is too high. Stop the vehicle, switch off the engine and
wait for it to cool down. If the warning lamp starts flashing again
after just a short distance, contact a qualified workshop.
WARNING
•
Before opening the bonnet and checking the coolant level,
please observe the warning information on ⇒page 255, “Working
on components in the engine compartment”.
•
Never open the bonnet if you can see or hear steam or coolant
escaping from the engine compar tment; there is a risk of being
scalded. Wait until you can no lo nger see or hear escaping steam
or coolant.Caution
•
Additional lights and other accesso ries in front of the air inlet
reduce the cooling effect of the radiator. At high outside tempera-
tures and high engine loads, there is a risk of the engine over-
heating.
•
The front spoiler also ensures proper distribution 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.
You should obtain professional assistance.
Rev counter
The rev counter indicates the number of engine revolu-
tions per minute.You should select a lower gear if the engine speed drops below
1500 rpm. The start of the red zo ne on the dial indicates the
maximum engine speed which may be used briefly when the engine
is warm and after it has been run in properly. However, it is advisable
to change up a gear or move the se lector lever to “D” (or lift your
foot off the accelerator) before the needle reaches the red zone.
Caution
Never allow the rev counter needle ⇒page 11, fig. 2 to go into
the red zone on the dial for more than a very brief period: there is a
risk of damaging the engine. The start of the red zone on the dial is
different for some engine versions.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise
engine noise.

Working on components in the engine compartment
Extra caution is necessary when working on components
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 observe the warn-
ings listed below and follow al l normal safety precautions. The
engine compartment of any motor vehicle is a potentially
hazardous area . ⇒ .
WARNING
•
Switch off the engine.
•
Remove the ignition key.
•
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 compartment.
•
Never spill fluids on hot engine components. These fluids can
cause a fire (e.g. radiator anti-freeze).
•
Take care not to cause short circ uits in the electrical system,
especially when working on the battery.
•
Do not touch the radiator fan when the engine is hot. The fan
may start running suddenly.
•
Do not unscrew the cap on the ex pansion tank when the engine
is hot. The cooling system is under pressure.
•
Protect face, hands and arms by covering the cap with a large,
thick rag to protect against escaping coolant and steam.
•
If any tests have to be performed with the engine running,
there is an extra safety risk from the rotating parts, such as the
drive belts, alternator and radiator fan, etc., and from the high-
voltage ignition system.
•
Vehicles with automatic gearbox: Never open the throttle inad-
vertently (for instance by hand from the engine compartment) if a
gear is engaged while the vehicle is stationary with the engine
running. The vehicle could otherwise start moving immediately
and possibly cause an accident.
•
Observe the following a dditional warnings if work on the fuel
system or the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near naked flames.
− Always keep an approved fire extinguisher immediately
available.Caution
When topping up fluids make sure the correct fluid is put into the
correct filler opening. This can otherwise cause serious malfunc-
tions or engine damage.
For the sake of the environment
Inspect the ground un derneath your vehicle regularly so that any
leaks are detected at an early stag e. If you find oil spots or other
fluids, have your vehicle inspected by a qualified workshop.
Note
On right-hand drive vehicles* some of the containers / reservoirs
mentioned below are located on the other side of the engine
compartment.

Wheels and tyres
268Wheels and tyresWheelsGeneral notes–When driving with new tyres , be especially careful during
the first 500 km.
– If you have to drive over a kerb or similar obstacle, drive very slowly and as near as possible at a right angle to the
kerb.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign bodies embedded in
the treads.
– Damaged wheels and tyres must be replaced immedi- ately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as possible.
– Mark the wheels before taking them off so that they rotate in the same direction when put back.
– When removed, the wheels or tyres should be stored in a cool, dry and preferably dark place.New tyres
New tyres do not give maximum grip straight away and should
therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km. This will also help to make the tyres last
longer.
The tread depth of new tyres may vary, according to the type and
make of tyre and the tread pattern. Concealed damage
Damage to tyres and rims is often
not readily visible. If you notice
unusual vibration or the car pulling to one side , this may indicate
that one of the tyres is damaged. Reduce speed immediately if there
is any reason to suspect that damage may have occurred. Inspect
the tyres for damage. If no external damage is visible, drive slowly
and carefully to the nearest qualified workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on
tyres with directional tread. Always note the direction of rotation
indicated when mounting the wheel. This guarantees optimum grip
and helps to avoid aquaplaning, excessive noise and wear.
Tyre service life
Correct inflation pressures and sensible driving habits
will increase the service life of your tyres.– Check the tyre pressures at least once a month.

Wheels and tyres273
Controls
Safety
Driving tips
General maintenance
Self-help
Technical data
In winter road conditions winter tyres will considerably improve the
car's handling. Due to their type
of construction (width, rubber
compound, tread pattern), summer tyres give less grip on ice and
snow. This applies particularly to vehicles equipped with wide
section tyres or high speed tyres (code letters H, V or Y on the side-
wall).
Only use winter tyres of the correct type approved for your vehicle.
The sizes of the winter tyres approved for your vehicle are listed in
the vehicle's documents (e.g. EC Certificate of Conformity or COC
document
4)). The vehicle documents vary depending on the
country of residence. Also refer to ⇒page 270 , ⇒ page 270 .
Winter tyres are no longer fully effective when the tread is worn
down to a depth of 4 mm.
The performance of winter tyres is also severely impaired by ageing,
even if the tread is still much deeper than 4 mm.
Winter tyres are subj ect to the following maximum speed limits
according to speed rating code letter: ⇒
In Germany vehicles capable of exceeding these speeds must have
an appropriate sticker attached so it is visible to the driver. Suitable
stickers are available from Audi dealers and specialist retailers.
Please note regulations to this effect in your country. “All-weather” tyres can also be used instead of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable 240 km/h speed rating for
winter tyres with the letter "V" is subject to
technical restrictions;
the maximum permissi ble speed for your vehicle may be signifi-
cantly lower. The maximum speed limit fo r tyres with a V-rating
depends directly on the maximum axle weights for your car and on
the listed weight rating of the tyres being used.
It is best to contact an Audi dealer to check the maximum speed
which is permissible for the V-rated tyres fitted on your car on the
basis of this information.
WARNING
Exceeding the maximum speed per mitted for the winter tyres
fitted on your car can cause tyre failure, resulting in a loss of
control of the vehicle – risk of accident.
For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give
better handling on roads which are free of snow and ice. Summer
tyres produce less rolling noise, do not wear down as quickly and,
most importantly, reduce fuel consumption.Snow chains
Snow chains will improve the vehicle's handling on snow-
covered roads.– Snow chains can be used on the front wheels only.
– Keep your speed below 50 km/h.Snow chains will improve braking ability as well as traction in winter
conditions.

Rear towline anchorage
Vehicles which do not have a factory-fitted towing
bracket* have a towline anchor age on the right side of the
rear bumper.Vehicles with towline anchorage
– Take the towline anchorage out of the vehicle's tool kit.
– To detach the cover cap from the bumper, firmly press
the lower part of the cap inwards to release it ⇒fig. 282.
– Screw the towline anchorage firmly all the way into the screw connection.
Vehicles with towing bracket*
– Fit the towing bracket.
– Attach the towbar or the towrope to the towing bracket.After use, unscrew the towline anchorage and put it back in the
toolbox. Replace the cap in the screw connection. The towline
anchorage or towing bracket should always be kept in the vehicle.
Vehicles which have a factory-fitted towing bracket* do not have a
screw connection at the rear for the towline anchorage.
WARNING
•
If the towline anchorage is not screwed in as far as the stop,
there is a risk of the screw connection shearing off during towing
(accident risk).
•
If your car has a towing bracket*, please use only special tow
bars with suitable attachments (i .e. tow bars which are specially
designed for use with towing brac kets) to avoid damage to the
coupling equipment.
•
If your car has a towing bracket*, please use only special
towing ropes (risk of accident).
To w - s t a r t i n g
As a general rule, tow-s tarting is not recommended.– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch on the ignition.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts: press the clutch and put the
gear lever in neutral.If the engine will not start, it is best to try starting it using the
battery of another vehicle ⇒page 293 before attempting to tow
start. You should only try to tow-start the engine if jump-starting is
not successful. Tow-starting is an attempt to start the engine via the
movement of the wheels.
When tow-starting a vehicle with a petrol engine, do not tow it more
than a short distance, otherwise unburnt fuel can enter the catalytic
converter and cause damage.
For technical reasons, it is not possible to tow-start a vehicle with
automatic gearbox .
