Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll 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
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is will reduce eng ine wear and improve
the m ileage.
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
@ Note
When driving on poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Driving through water on roads
Note the following to reduce the r isk 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 .
56
-Do not drive faster than walking speed .
A WARNING
After driving through water or m ud, the effec­
tiveness of the brakes may be red uced due to
mo isture on the brake rotors and brake pads.
A few careful brake applications shou ld dry
off the brakes and restore the full braking ef­
fect .
@ Note
Vehicle components such as the engine,
transmission, suspension or electr ica l system
can be severely damaged by driving through
water.
{D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch t he engine off whe n driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep fo r yo ur vehicle to drive
throug h safe ly.
- Avoid driv ing th rough salt water, because
this ca n cause cor rosion .
Economical and environmentally-friendly
driving
The amount o f fuel consumption, the environ ­
mental impact and the wear to the engine,
bra kes and tires depends mostly on your d riving
style. With an ant icipatory and economic driving
sty le, fuel consumpt ion can be reduced by ap­
prox imately 10-15% . The follow ing t ips will help
you conserve the environment and your money at
t h e same time .
Anticipatory dri ving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you acce lerate less .
When poss ible, let you r vehicle coast with a
gear
engag ed ,
for examp le, when you not ice that the
next t raff ic light is red.

Intelligent Technology
Wear
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 city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
I n certain situations, for example after dr iving
through water, in heavy ra in or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads . The brakes must be "dried" first with 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 . This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and
pads¢ &.
Brake system malfunction
If you notice that the brake pedal travel has sud ­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Aud i dea ler or authorized
Aud i Serv ice Facility immediately to have the
88
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.
Low brake fluid level
When the brake fluid level is low, malfunctions in
t h e brake system may occur . The brake fluid leve l
is electronically monitored .
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
- 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 compensate for the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- On ly app ly 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
r is k of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gea r or lower selector leve r po­
sition. Drive as lit tl e as possible while press­
ing the brake pedal and avo id putting yo ur
left foot on the brake pedal while driv ing .
This could ca use the brakes to overheat and
impair the efficiency of th e brakes.
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces­
sarily.
- Certain weather and operating conditions such as driving through water, dr iv in g in
heavy rain or driv ing after wash ing your ve­
h icle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these compon ents by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up.

-The efficiency of the brakes can also be im­
paired by driving for long stretches on roads
covered with salt without using the brakes .
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated proper ly . Otherwise,
the b rake system could overheat, w hich re­
duces the ir effectiveness.
- Failure of a brake c ircuit impa irs b raking
perfo rman ce , which increases brak ing dis ­
tan ce. Avoid d riving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of an
accident.
- If the brake booster is not working, you will
have to press much harder on the brake
peda l to compensate for the lack of the
booster.
@ Note
- Never let the brakes "rub" by pressing the
pedal light ly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear.
- Before driving downhi ll a long distance on a
steep h ill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes . If
you need to brake additionally, brake in in­
tervals and not conti nuous ly .
0) Tips
- If the brake booster is not working, you
must press the brake pedal with much more
fo rce t han normal.
- If you retrofit your vehicle with a front spoil­
er, whee l covers o r similar items, make sure
t h at the a ir flow to the front whee ls is not
i nte rru pted. Ot herw ise the brake system
ca n become too ho t.

- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
hous ings.
- After wash ing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
c reases the risk of an acc ident. The brakes
must be d ried fi rst w it h a few careful b rake
applications.
@ Note
- If you wash the vehicle in an automatic car
wash, you m ust retract the extendable rear
spo ile r* if necessary, and fold the exter ior
mir rors in to red uce the r isk of damage.

- T o red uce the risk of damage to the s urface,
do not use insect removing sponges, kitchen
sponges or similar items .
- Mat te finish painted veh icle components:
- To reduce the risk of damage to t he sur-
face, do not use po lish ing 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 cou ld be damaged
when the stickers or magnets are re­
moved.

Emergency assistance
{QJ 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.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
¢ page 278.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
sidewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire 's optimum performance in regard to ad­
hesion, running noise, friction and 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.
Finishing
.,. Reinstall the caps on the wheel bolts if neces­
sary .
.,. 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 183.
.,. Check the tire pressure on the installed wheel
as soon as possible.
.,. Check the tire pressure and store it in the Info­
tainment system.
.,. The wheel bol t tightening specification must be
90 ft lbs (120 Nm) . Check it as soon as possible
with a torque wrench. Drive carefully until then.
.,. Have the faulty wheel replaced as quickly as
possible.
278
(D Tips
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
Notes on wheel changing
Please read the information ¢ page 251 if you
are going to use a spare tire which is different
from the tires on your vehicle .
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90
ft lbs (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover .
Until then, drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read
the information
¢page 251.
-Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the ve­
hicle.
