Driving
General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed (RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration 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
higher 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 per iod, part icularly 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 when the engine no longer runs
"smoothly" . Extremely high engine speeds are
automatically reduced.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for examp le
<( on flooded roads : a, .... N
~ -The wate r must not be any higher than the bot-....
g tom of the vehicle body .
3 a,
Driving
- Do not drive faster than walking speed.
A WARNING
After driv ing 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 .
(D Note
-Vehicle components such as the engine,
transmission, suspens ion or electrical sys­
tem can be severely damaged by driving
through water .
- Always switch the Start/Stop system* off
when driving through water
r:';>page 78.
(D 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
T he amount of fuel consumpt ion, 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
engaged,
for example, when you notice that the ..,.

Intelligent Technology
- The re is no vehicle stabilizat ion when ESC/
ASR are switched off.
Braking
New brake pads
New b rake pads do not achieve the ir 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 brak ing force by
pressing firmly on the brake pedal. Avoid heavy
braking dur ing the break-in per iod.
W ear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the c ity and on curves or with a sporty driving
style .
Operating noise
Noises may occur when braking depending on the
speed, b raking force and outside conditions such
as tempe rature and humidity.
W et conditions or road salt
In certain s ituations, for example after dr iving
through water, in heavy rain or after washing
your car, the brak ing effect may be reduced due
to mo isture or ice on the brake rotors and brake
pads. The brakes must be "dr ied" first wit h a few
careful brake applications.
At higher speeds and with the windshie ld 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 driver, happens at regular
i n tervals a nd ensu res a better reaction time for
the bra kes in wet weather .
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the
brakes fo r long periods of time . The laye r of salt
on the brake rotors and pads must be wo rn off
fi rst when the b rakes are app lied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avo iding heavy brak ing
136
can con trib ute to corros ion on t he b rake roto rs
and to dirty brake pads .
I f you usu all y avoid he avy br aking 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 not ice that the b rake peda l t ravel has sud­
denly gotten larger, t hen a b rake c ircuit in the
dual-c ircuit brake system may have failed. Drive
to an authorized Audi dea ler o r authorized Audi
Se rvice Facility immediate ly to have the prob lem
corrected . On the way there, dr ive with reduced
speed and keep in mind tha t you w ill need a lon­
ger distance to stop and you will need to press
the brake pedal harder.
l o w brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
i s electronically monitored.
Brake booster
The bra ke boos ter amp lifies the p ressure yo u ap ­
ply to the brake pedal. It only wor ks when the en­
gine is running .
A WARNING
- Only app ly the bra kes for the purpose o f
cleaning the brake system w hen road and
traffic conditions permit. You must not en­
danger other road users. This i ncreases the
r is k of an accident.
-
- Never let the ve hicle roll while the engine is
s to pped because t his i ncreases the ris k of an
acciden t.
Q) Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually
necessary . This causes t he b rakes to over ­
heat and incr eases brak ing distanc e and
c a u ses we ar.
- Before driving a long d istance o n a steep
d ownward hill, decrease your speed a nd se-
le ct a lo wer driving gear. This m akes use of

Care and cleaning
& WARNING
-Only wash the vehicle when the ignition is
off or follow the instruct ions from the car
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 t he wheel
hous ings.
- After was hing the vehicle, the braking effect
may be delayed due to mo isture on the
bra ke rotors o r ice i n the winte r. This in­
c reases the risk of an a cciden t. The bra kes
must be dried first with a few care ful brake
applications .
@ Note
-If you wash the ve hicle in an automa tic car
wash, yo u must 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 us ing 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 ith the distance be­
tween t he gu ide rai ls in the car wash. -
To red uce the risk of damage, compare the
heig ht and width of your vehicle with the
heig ht and w idth of the inside of the car
wash.
- To prevent paint damage, do not wash the
vehicle in direct sunlight.
- To reduce the risk of damage to the surface,
do not use insect removing sponges, k itchen
sponges or s imilar items.
- Matte finish painted vehicle components:
- To reduce the r isk 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 pain ted with matte
finish paint. The paint could be damaged
when the stickers or magne ts are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facilities spe cially de­
signed for that pu rpose. This will reduce the
r isk of dirty wate r contamina ted with o il from
entering the sewer system .

Removing a wheel
., Remove the top wheel bolt complete ly using
the hex socket in the screwdriver hand le (in the
vehicle tool kit)
c::> fig. 266 and place it on a
clean surface .
., Install the alignment pin (from the vehicle tool
kit) by hand into the empty hole
c::> fig. 267 .
., Remove the rest of the wheel bolts.
., Remove the wheel. The alignment pin remains
in the hole while doing this.
Install a wheel
Read the directions on c:> page 348 when instal­
ling unidirectional tires.
., Slide the wheel on over the alignment pin.
., Install the wheel bolts and tighten gent ly using
the hex socket.
., Remove the alignment pin and also tighten the
remaining wheel bo lt .
., Carefully lower the vehicle using the vehicle
jack* .
., Tig hte n the wheel bolts i n a diagona l pattern
using the wheel wren ch.
348
The wheel bolts must be clean and loosen/tight ­
en easily . Check the contact surfaces for the
wheel and hub. Contam inants on these surfaces
must be removed before installing the wheel.
A WARNING
Never use the hex socket in the screwdriver
handle or the hex socket wrench w ith the
ratchet to loosen or tighten the wheel bolts.
This increases the risk of an accident, because
you will not reach the tightening specification
required.
(D Note
When removing or instal ling the wheel, the
r im could hit the brake rotor and damage t he
rotor. Work carefully and have a second per­
son help yo u.
@ Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
c::> page 348.
- The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mati ng surfaces of both the wheel and the
hub. Remove all dirt from these sur faces be­
fore remounting the whee l.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
s idewall. You must always adhere to the speci­
fied running direction . Th is is necessary ensure
the tire's opt imum performance in regard to ad­
hesion, running noise, friction and hyd roplaning.
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
r un ning direction on all of the tires.
Finishing
., Re install the caps on the wheel bolts if neces­
sary .
., Store the vehicle tool kit in its designated
place . ..,.
