General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not drive at speeds
that will exceed 2/3 of the maximum perm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
h igher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine. This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
CD Note
When driving on poor roads, by curbs and on
steep ramps, make su re that low-hang ing
components such as the spoi ler and exhaust
system do not come into contact with these
or 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 driv ing through water, for example
on flooded roads:
-The water must not be any higher than the bot­
tom of the vehicle body .
74
-Do not drive faster than walking speed .
A 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.
CD 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 81.
(i) 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 .
Economical and environmentally-friendly
dr iving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
sty le. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­
proximately 10-15%. The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged,
for example, when you notice that the ..,.

-There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
-ESC/ASR cannot be switched off or sport
mode cannot be switched on if the cruise
control system * or the adaptive cruise con­
tro l* is sw itched on.
-Malfunctions in the Audi magnetic ride *
may make it imposs ible to switch the ESC/
ASR off or to switch sport mode on.
Brakes
New brak e pad s
New brake pads do not achieve their full braking
effect during the first 2S0 mi (400 km) . They
must be "broken in" f irst. 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 per iod.
Wear
B rake pad
wear depends largely on the way the
veh icle is driven and on operat ing cond itions.
This is especially true if you are driving frequently
in the c ity and on curves or with a sporty driving
style.
Operat ing no ise
Noises may occur when braking depending on the
speed, braking force and outs ide cond itions such
as temperature and humidity .
Effect of wat er and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con ­
densation or after washing your car, the braking
effect can be reduced by moisture or ice on the brake rotors and brake pads . The brakes must be
"dr ied" first w ith a few careful brake applica­
tions .
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. Th is action,
which is not felt by the d river , happens at regular
Intellig ent Technology
interva ls and ensures a better reaction time for
the brakes in wet weather.
T he brak ing effect ca n also be reduced if yo u are
driv ing on sal ted roads and yo u do not app ly the
brakes for long per iods o f time. The layer o f salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leav ing the veh icle pa rked for long periods of
time, low mileage and avoiding heavy b raking
can contribute to corrosion on the brake roto rs
and to dirty brake pads .
If you usua lly avoid heavy bra king or if there is
corrosion present, occasiona l heavy brak ing at
high speeds is recommended to clean the brake
rotors and
pads ¢,& .
Brake system malfunction
If you notice that the bra ke pedal travel has sud ­
denly inc re ased, then a br ake circuit in the dua l­
c ircuit b rake system may have malfunctioned.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediate ly to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
L o w bra ke fluid le ve l
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level is electronically monitored.
Brake bo oster
The brake boos ter amplifies the p ressure you ap ­
ply to the brake pedal. It on ly operates whi le the
engine is running or when the ignition is switched
on (p lug-in hybrid dr ive*) .
A WARNING
-Only app ly the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permit. You must not en­
danger other road users. This increases the
risk of an accident.

Care and cleaning
A WARNING
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- 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 mo isture on the
brake rotors or ice in the winter. This in­
creases the risk of an acc ident. The brakes
must be d ried first w ith a few careful b rake
applications.
(D Note
- If yo u wash the ve hicle in an automatic car
wash, yo u m ust fold the exte rior m irrors i n
to reduce the risk of damage to the mir rors.
Power folding exte rior mir rors* mus t onl y
b e fo lded i n and ou t using the powe r folding
funct ion .
- T o reduce t he risk of paint damage, do no t
wash the vehi cle i n dire ct sunlig ht.
-
- To red uce the risk of damage, do not wash
the power top* with a pressure washer.
- T o reduce the risk of damage to the s urface,
do not use insect removing sponges, kitchen
sponges o r similar items .
- Mat te finish painted vehicle components:
- To reduce the r isk of damage to the sur-
face, do not use polis hing 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 veh icle in facili ties spec ially de­
s igned for that pu rpose. This will reduce the

Putting on the c omp act spare wheel
.. Lift the spare wheel and carefully slide it over
the alignment p in to gu ide it in place
<=>(j) .
.. Use the hexagonal socket in the screwdr iver
handle to screw in and t igh ten all wheel bolts
slightly.
.. Remove the alignmen t pin and insert and t igh t­
en the remaining wheel bolt s light ly like the
rest .
.. Turn the jack hand le counter-clockwise to lower
the vehicle until the jack is fully released .
.. Use the wheel bolt wrench to tighten all wheel
bolts
firmly <=> page 358. Tighten them cross­
wise,
from one bolt to the (approximately) op ­
posite one, to keep the wheel centered.
