Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal.
A WARNING
- When applying the brakes to clean off de­
posits on the pads and discs, select a clear,
dry road. Be sure not to inconvenience or en­
danger other road users; do not risk an acci­
dent.
- Never let the car coast with the engine
switched off (this can cause accidents).
CD CAUTION
- Never let the brakes "drag" by leaving your
foot on the pedal
when
you do not really in­
tend to brake. This overheats the brakes, re­
sulting in longer stopping distances and
greater wear.
- Before driving down a long, steep gradient,
it is advisable to reduce speed and select a
lower gear. In this way you will make use of
the engine braking effect and relieve the
load on the brakes. If you still have to use
the brakes, it is better to brake firmly at in­
tervals than to apply the brakes continuous­
ly.
� Note
-If the brake servo is out of action, you must
apply considerably more pressure to the
brake pedal than you normally would.
- If you wish to equip the car with accessories
such as a front spoiler or wheel covers, it is
important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat.
Electro-mechanical
power steering
Electro-mechanical power steering assists the
driver when steering.
The degree of power assistance is adapted elec­
tronically, depending on the speed.
116 Warning/indicator
lamps and driver
messages
• Steering: fault. Please stop vehicle
If the warning lamp Lights up permanently and
the message appears, there may be a power
steering failure.
Stop the vehicle in a safe place as soon as possi­
ble. Do NOT drive on. Obtain professional assis­
tance.
� Steering: fault. You can continue driving
If the indicator lamp lights up, the steering re­
sponse may be heavier or Lighter than usual. In
addition, it is possible that the steering wheel
will be off centre when driving in a straight Line.
Drive slowly to a qualified workshop and have the
fault rectified.
('!)) Note
You can drive on if the warning/indicator
lamp . or� Lights up only briefly.
Four-wheel drive
(quattro)
Applies to: vehicles with four-wheel drive
On quattro models the engine power is distrib­
uted to all four wheels.
General notes
On four-wheel drive vehicles, the engine power is
distributed to all four wheels. The distribution of
power is controlled automatically according to
your driving style and the road conditions. Also
refer to¢ page 113, Electronic stabilisation con­
trol (ESC).
The four-wheel drive is specially designed to
complement the superior engine power of your
Audi. This combination gives the car exceptional
handling and performance capabilities -both on
normal roads and in more difficult conditions,
such as snow and ice. Even so (or perhaps espe­
cially for this reason), it is important to observe
certain safety points¢&.

belts
Seat belts
Why 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.
Fig. 188 Driver with correctly positioned seat belt -good
protection if the brakes are applied suddenly
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.
When worn correctly, seat belts hold the occu­
pants in the best position for maximum protec­
tion ¢ Fig. 188. The seat belts are capable of ab­
sorbing much of the kinetic energy which is gen­
erated in a collision. They also help to prevent
uncontrolled movements which could lead to se­
vere injuries ¢ page 230, Important safety
notes when using seat belts.
If they wear the seat belts correctly, the passen­
gers benefit greatly from the ability of the belts
to reduce 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 colli­
sion. Taken together, all these features reduce
the forces acting on the occupants and conse­
quently the risk of injury.
Although these examples are based on a frontal
collision, the physical principles involved are the
same in other types of accidents. This is why it is
so important to put on the seat belts before ev­
ery trip -even when "just driving around the cor-
230 ner".
Please also ensure that your passenger's
seat belt is properly fastened ¢ A.
Seat belts worn correctly 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 231, Forces acting in a
collision.
For information on how children can travel safely
in the car refer to¢ page 223, Child seats.
_& WARNING
- Seat belts must be put on before every trip -
even when driving in town. This also applies
to passengers -risk of injury!
- 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 233, Wearing and adjust­
ing the seat belts during pregnancy.
Important safety notes when using seat
belts
There are a number of safety points concerning
the seat belts which you should remember. This
will help to reduce the risk of injury in an acci­
dent.
_& WARNING
- The seat belts can only provide maximum
protection if the seats are adjusted properly
¢ page 54, Front seats.
- To ensure proper protection, it is important
to wear the seat belts in the correct position
¢ page 232, How to wear seat belts prop­
erly. Ensure that the seat belts are worn ex­
actly as recommended in this chapter. Belts
which are not worn properly can increase
the risk of injury in accidents considerably.
- Do not allow the seat belt to become twis­
ted or jammed, or to rub on any sharp
edges.
- Never allow two passengers (even children)
to share the same seat belt. It is especially
dangerous to place a seat belt over a child
sitting on your lap.

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.

page 244.
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.

means, for example, that the tyre was produced
in the 22nd week of 2016.
Audi Genuine Tyres
Audi Genuine Tyres with the marking "AO" are
specially matched to your Audi. When used prop­
erly, these tyres meet the highest standards in
safety and handling. Your specialist retailer will
be glad to provide more information.
_& WARNING
- Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicle and an accident could
result.
- For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
- It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size
marked on the tyre; with some makes of
tyre the effective tyre size can differ signifi­
cantly from the nominal dimensions, even
though the tyres have the same size desig­
nation. Inadequate tyre clearance can result
in damage to the tyres or the vehicle, caus­
ing a serious safety risk.
-Avoid running the car on tyres that are more
than 6 years old. If you have no alternative,
you should drive slowly and with extra care
at all times.
- The use of run-flat tyres on your vehicle is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
- If wheel trims are fitted after the car is pur­
chased, ensure that there is an adequate
flow of air for cooling the brakes -risk of ac­
cident!

which you are travelling. Wheels
Tyre wear / damage
Fig. 221 Tyre tread: Tread wear indicators
Tyre wear
Inspect the tyres regularly for damage.
- The wear on under or over-inflated tyres is sig­
nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
- If you notice excessive tyre wear, have the
wheel alignment checked by a qualified work­
shop.
- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicle may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators
¢ Fig.
221 running
across the tread at regular intervals. The letters
"TWI" or triangles on the sidewall indicate the
positions of the tread wear indicators.
The minimum tread depth 1
) is reached at the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
¢ _8..
Changing wheels round
Wheels should be changed round regularly to en­
sure that the wear is equal on all tyres. Fit the
wheels from the rear axle on the front axle and
vice-versa. All the tyres will then last for about
the same time.

vehicle with the ignition switched on -risk
of accident!
- To avoid cutting yourself on sharp metal
parts, always wear suitable protection when
cleaning the underside of the car or inside
the wheel arches.
-After the car has been washed, the full brak­
ing effect can be delayed by moisture (or in
winter by ice) on the discs and brake pads -
risk of accident! The brakes should be dried
by pressing the pedal to restore full braking
effect.
