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 .
74
-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 eng ine,
transmiss ion, suspens ion or electrical sys-
tem can be severely damaged by drivi ng
throug h water .
- Always switch the Start/Stop system* off
when driv ing through water¢ page 79.
(D Tips
-Determine the depth before driving throug h
water.
- Do not stop the vehicle, drive in reverse or
switch t he engine off when 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 dr iv ing through salt water, beca use
this can cause corrosion .
Economical and environmentally-friendly
driving
The amou nt o f fuel consumption, the environ ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
sty le. With an ant icipatory and economic driving
style, fuel consumpt ion can be reduced by ap­
prox imately 10-15%. The fol low ing t ips will help
you conserve the environment and your money at the 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 your vehicle coast with a gear .,.

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
In certain situations, for example after driving
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 windsh ie 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 salted roads and you do not apply the
brakes for long periods of time . The layer of sa lt
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
high speeds is recommended to clean the brake
rotors and pads¢
A.
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 Audi dea ler or authorized
Audi Service Facility immediately 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 w ill need
to press the brake pedal harder .
Intelligent Technology
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
is e lectronica lly monitored.
Brake booster
T he brake booster amplifies the pressure you ap­
ply to the brake pedal.
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
peda l harder.
& WARNING ~ -
- On ly 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 .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- Never place objects in the dr iver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You would not be able to use the ped­
als if sudden driv in g or braking maneuvers
were needed, which increases the ris k of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwells.
- To reduce the risk of injury, do not place
your foot under the brake pedal.

Care and cl eaning
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when was h­
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 it h a few careful b rake
applications.
@ Note
- If you wash the ve hicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors .
P ower folding exte rior m irrors* must o nly
be fo lded in and out using the powe r folding
f u nct io n.
- To reduce t he risk of damage to the rims
and t ires , compare the width be tween the
whee ls on your ve hicl e w it h t he distance be ­
tween the g uide rai ls in the car wash .
- To reduce t he risk of damage, compare the
height and width o f you r vehicle with the heig
ht and w idth of the inside o f the car
was h.
- T o red uce the risk of pa in t damage, do not
was h the vehicle in direct sun light .
- T o red uce the risk of d amage to the s urf ace,
do not use insect removing sponges, k itchen
sponges or similar items .
- Matte 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 magnet ic
signs on vehicle parts painted with matte
finish paint . The paint cou ld be damaged
when the stickers or magnets are re­
moved .
@ For the sake of the environment
Only wash the ve hicle in facilities spec ia lly de­
s igned for that pu rpose . This will reduce the
r isk of dirty wate r contaminated with o il from
ente ring the sewe r system.

(D Tips
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
c> page 362.
-Th e 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 un idirectional tire profi le is identified by arrows
that point in the running direct ion on the tire
s idewa ll. You must always adhere to the speci­
fied running direction. This is necessary ensure
t h e 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 rep lace fau lty
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 veh icle tool k it in its designated
place .
• Store the replaced tire securely in the luggage
compa rtment
¢page 257.
• Check the tire pressure on the insta lled wheel
as soon as possible.
• Cor rect the tire pressure and store it in the In­
fotainment system ¢
page 349.
• The wheel bolt tightening specification must be
120 ft lbs (160 Nm). Check it as soon as possi­
ble with a torque wrench. Drive carefully until
then .
• Have the faulty wheel replaced as quickly as
possible .
