Driving

Vehicle starting system: malfunction! Please
contact Service
There is a malfunction in the Start/Stop system.
Drive the vehicle to an authorized Audi dealer or
authorized Service Facility as soon as possible to
have the malfunction corrected.
Brakes
General information
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimal braking effect, the brake sys-
tem is cleaned at regular intervals. This is done
by applying the brake pads to the brake rotors for
a short period of time when driving at high
speeds when the windshield wipers are switched
on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
Brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Ceramic brakes
Applies to: vehicles with ceramic brakes
Ceramic brakes provide excellent deceleration
rates.
The break-in period for new ceramic brakes may
be significantly longer than for standard brake
rotors. Due to the properties of the material,
they may cause noises at lower speeds. Ceramic
brakes also absorb more moisture in wet condi-
tions. Therefore, there will temporarily be less
braking force than when the brakes are dry. You
can compensate for this by pressing the brake
pedal harder.

ZA\ WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users. This increases the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To reduce the risk of injury, do not
place your foot under the brake pedal.

@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually

Care and cleaning


—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.

@) Note
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be-
tween the guide rails in the car wash.
—To reduce the risk of damage, compare the
height and width of your vehicle with the
height and width of the inside of the car
wash.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
— Matte finish painted vehicle components:
—To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
— Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re-
moved.
@) For the sake of the environment
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
Cleaning and care information
When cleaning and caring for individual vehicle
components, refer to the following tables. The
information contained there is simply recommen-
dations. For questions or for components that

Emergency assistance

The wheel bolts must be clean and loosen and
tighten easily. Check the contact surfaces for the
wheel and hub. Contaminants on these surfaces
must be removed before installing the wheel.

Z\ WARNING
— Read and follow the important information
and notes under > page 223.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex socket will not achieve the required
tightening torque, which increases the risk
of an accident.
C) Note
When removing or installing the wheel, the
rim
could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
hydroplaning.

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment > page 73.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it
=> page 235.

> The wheel bolt tightening specification must be
100 ft lbs (140 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
Spare tire
tute Mae eis
Applies to: vehicles with subwoofer
The subwoofer must be removed before the
spare tire*/temporary spare tire* can be re-
moved.


Fig. 161 Spare tire well: subwoofer
Removing the subwoofer
> Pull out the red connector lock @).
>» Remove the connector (2) and set the discon-
nected cable aside.
> Turn the handwheel counter-clockwise and re-
move it.
> Carefully remove the subwoofer.
Installing the subwoofer
> Carefully place the subwoofer in the rim well.
The word “FRONT” on the subwoofer must face
forward.
> Insert the connector that was removed.
> Secure the subwoofer with the handle.

The spare tire is intended for short-term use only.
Have the damaged tire checked and replaced, if
necessary, by an authorized Audi dealer or au-
thorized Audi Service Facility as soon as possible. >
