Driving
General information
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
tion. The engine can be increased RPM gradually
during the next 300 miles (500 km).
Reducing the risk of vehicle damage
@ Note
When driving on poor roads, over curbs, and
on steep ramps, make sure that components
that hang below the vehicle, such as the spoil-
er and exhaust system, are not struck because
they could be damaged. This especially ap-
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
— The water must not be any higher than the bot-
tom of the vehicle body.
— Do not drive faster than walking speed.

ZA WARNING
After driving through water or mud, the effec-
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry off
the brakes and restore the full braking effect.


@) Note
— Vehicle components such as the engine,
transmission, suspension, or electrical sys-
tem, can be severely damaged by driving
through water.
— Always switch the Start/Stop system* off
when driving through water > page 62.
@) Tips
— Determine the depth before driving through
water.
— Do not stop the vehicle, drive in reverse, or
switch the engine off when driving through
water.
— Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
— Avoid driving through salt water, because
this can cause corrosion.

driving
The amount of fuel consumption, the environ-
mental impact, and the wear to the engine,
brakes, and tires depends mostly on your driving
style. Note the following information for efficient
and environmentally-conscious driving:
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system > page 62.
— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Utilize the engine braking effect.
— Avoid driving short distances or at high speeds
when possible.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Make sure the tire pressure is correct
=> page 254.

Intelligent Technology


— There is no vehicle stabilization when
ESC/ASR are switched off.

@) Tips
— When the cruise control system* is switched
on, ESC/ASR cannot be switched off or sport
mode cannot be switched on.
— Malfunctions in the rear spoiler, in the Audi
magnetic ride or in the all wheel drive sys-
tem* may make it impossible to switch the
ESC/ASR off or to switch sport mode on.
— Some driving tracks (such as ones with
steep curves) can influence the ESC per-
formance.
Brakes
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-
838
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 miles (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 and increase 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.
— Depending on vehicle equipment, the brake
pedal
may move downward automatically

during autonomous braking maneuvers. To

Care and cleaning


ZA WARNING
—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and fol-
low the instructions from the car wash oper-
ator.
—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 with a few careful brake appli-
cations.

©) Note
— If you wash the vehicle in an automatic car
wash, you must retract the extendable rear
spoiler* if necessary, and fold the exterior
mirrors in to reduce the risk of damage.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—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, do not wash
the power top with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing 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 components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
(*) 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.

Removing a wheel
> Remove the top and bottom wheel bolts com-
pletely using the hex socket in the screwdriver
handle (in the vehicle tool kit) > fig. 204 and
place it on a clean surface.
> Install the alignment pins (from the vehicle
tool kit) by hand into the empty holes
> fig. 205.
> Remove the rest of the wheel bolts.
> Remove the wheel >(@). The alignment pins re-
main in the holes.
Installing a wheel
Read the directions on > page 276 when instal-
ling unidirectional tires.
> Slide the wheel on over the alignment pins
>©.
> Install the wheel bolts and tighten them gently
using the hex socket.
> Remove the alignment pins and also tighten
the remaining wheel bolts.
> Carefully lower the vehicle using the vehicle
jack*.
276
> Tighten the wheel bolts in a diagonal pattern
using the wheel wrench.
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.

ZA WARNING
— Read and follow the important information
and notes under > page 251.
— 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.
(!) 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.
> Make sure that the wheel that was removed,
the vehicle tool kit, and the vehicle jack* are se-
curely stored in the luggage compartment
