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
(D 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 .
86
-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 and restore the full braking ef­
fect .
{CT) 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
91.
@ 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 safe ly .
-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
style. 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

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving abilities
and road conditions permit .
- The stabilization function is limited when
sport mode is sw itched on . T he driving
wheels co uld spin and the vehicle cou ld
swerve, espec ially on s lick o r sli ppery roa d
surf aces.
- T here is no vehicle stabilization when ESC/
ASR a re swi tched off .
Brakes
New brake pads
New brake pads do not ac hieve the ir full b raking
effect during the first 250 mi (400 km) . They
must be "broken
in " fi rst . However, you can com­
pensate for the slightly reduced bra king fo rce by
pr ess ing firmly o n the bra ke pe dal. Avoid heavy
b ra king dur ing t he b reak -in per io d .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions .
This is especially t rue if you are d riving freque ntly
in t he c ity and on curves o r wi th a sporty driving
s tyle.
Operating noise
Noises may occur when braking depend ing o n the
speed , braking force and ou ts ide cond it ions such
as te m pe ra ture and humi dity .
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy ra in or after washing
your car, the braking ef fect may be reduced due
to mo isture or ice on the b rake roto rs and b rake
pads. The b rakes mus t be
"dried" firs t wi th a few
care ful bra ke app lic at ions.
At higher speeds and with t he windsh ie ld wipers
turned o n, the brake pads press against the bra ke
rotors for a s ho rt amoun t of time. This ac tion,
whi ch is not felt by the driver , happens at regul ar
i nte rvals an d ens ures a better reac tion time fo r
the brakes in wet weat her.
Intellig ent Technology
The brak ing effec t can a lso be reduced if yo u are
driving on salted roads and yo u do not app ly the
bra kes for long per iods o f time. The layer of sa lt
on the brake rotors and pads m ust be worn off
first whe n the brakes are applied .
Corrosion
Leaving t he vehi cle pa rked for long periods o f
time, low mileage and avoiding heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if there is
cor rosion prese nt, occasiona l heavy braking at
high speeds is recommended to clean the brake
roto rs and pads
c> ,& .
Brake system malfunction
If you notice that the bra ke pedal trave l has sud ­
denly in crease d, then a brake circuit in the dua l­
circuit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
Audi Se rvice Facility immed iate ly to have the
problem corrected. On the way there, d rive w ith
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the bra ke ped al ha rder.
Low brake fluid level
When the bra ke fluid level is low, malfu nctions in
the b rake system may occur . T h e brake fluid level
is e lec tron ically moni tored.
Brake booster
The brake booster ampli fies t he p ressure you ap­
ply to the brake pedal.
A WARNING
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permi t. You must not en ­
da nger other road users. This inc reases the
ris k of an a ccid en t.
- Never let the vehicle roll while the engine is
sto pped bec ause t his increases the risk of an
a ccident.

wash operator to reduce the risk of acci­ dents .
- To reduce the risk of cuts, protect yourself from sha rp metal components when wash­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the bra king effect
may be de layed due to mo isture on the
bra ke rotors or i ce in the w inte r. This in­
cre ases the risk of an ac ciden t. T he bra kes
must be dried first with a few careful brake
applications .
(D Note
-If yo u wash t he ve hicl e in an au tom atic c ar
wash, yo u m ust fold the exterior m irrors in
to reduce the risk of damage to the mirrors .
Power folding exterior mirrors * must on ly
be fo lded in and out using the power folding
funct ion.
- To reduce the risk of damage to the rims
and tires, compare the width between the
whee ls on your vehicle w it h the distance be­
tween the g uide rails in the car wash .
- To reduce the risk of damage, compare the
height and width of your vehicle with the
