Brake system
Operating conditions and driving habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat
ing conditions and dr iv ing habits ¢&. . On
vehicles that are e ither driven mostly in stop
and -go city traffic or are driven hard, the
brake pads should be checked by your author
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure to have you
r brake pads inspected can result
in reduced brake performance.
On steep slopes , you should use the braking
effect of the engine . This way, you prevent un
necessary wear on the b rake system . If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter
vals.
Noises may occur when braking depending on
the speed, braking force and outside condi
t ions such as temperature and humidity .
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few careful brake applications should dry off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshie ld wipers on, the brake pads will
briefly touch the brake discs in regu lar inter
vals so as to improve reaction time when brak
ing on wet surfaces . You, the driver, will not
notice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Here too,
you should clean off accumulated salt coating from brake discs and pads w ith a few careful
applications of the brake ¢.& .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corros ion to form on
the discs if the car is not driven regularly or
o n Ly for short trips with little use of the
brakes.
If the brakes are not used frequently, or if cor
r os ion has formed on the d iscs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed¢ ,&. .,..

Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&. .
Low brak e flu id level
Malfunct ions can occur in the brake system if
the brake fl uid leve l is too low . T he b rake fluid
l eve l is monito red electronically .
Brake booster
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*) ~.&, .
Brake lining wear statu s
Brake lining wear may be checked by visual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sa ry, the wheel may be removed for this in
spection
~ page 2 74, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat
ings w ill be cleaned off after a few care
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in
creased stopping distance . Avoid driving
the vehicle and have it towed to the near
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers ):
.. Speeds ca n gradually be increased to the
maximum perm iss ible road or eng ine speed .
During and after break-in period
.. Do not rev the eng ine up to h igh speeds
when it is cold. Th is applies whether the
transmission is in N (Neutral) or in gear.
After the break- in peri od
.. Do not exceed maximum eng ine speed un
der any circumstances.
.. Upshift into the next higher gear
before
reaching the red area at the end of the tach
ometer scale
c.> page 10.
During the first few hours of driving, the en
g ine's internal friction is higher than later
when all the moving parts have been broken
in . How well this break -in process is done de
pends to a considerable extent on the way the
vehicle is driven du ring the first 1,000 miles
(1,500 k ilome ters).
(D Note
Extremely h igh engine speeds are auto
mat ica lly reduc ed. However , th ese rpm
lim its are programmed for a n engine well
r u n- in, not a new engine.
Driving and environment 205
@) For the sake of the environment
Do not drive with unnecessarily high en
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ
ment.
New tires
If your vehicle is running on new tires, drive
very carefully for the first 350 miles (500 ki lo
meters) after fitting.
.&, WARNING
N ew tires tend to be sl ippery and mus t al
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 ki lomete rs) afte r they are installed.
New brake pads have to be "burnished in" be
fore they have optima l grab
c.> .&. .
During the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
.&, WARNING
New b rake pads don 't have the best stop
p ing power and must be "broken-i n" dur
ing the initi al 100 to 150 miles (150 to
2 00 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing the b rake peda l more fi rm ly . This also applies
later when new pads are installed.

Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex
haust and noise levels .
Fue l economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your persona l driving style
- opera ting conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent . This sec
tion will give you some t ips on how you can
he lp the environment and your pocketbook.
(D Tips
The consumpt io n estimates as published
by ENVIRONMEN TAL PROTECTION AGENCY
(EPA) and Transport Ca nada may not corre
spond to your act ual consumption on the
road, wh ich will vary depending upon vehi
cle load and speed, road and weather con
ditions, trip length, etc .
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating.
" Avoid unnecessary acce lerating and braking .
Vehicles use the most fue l when they are ac
celerating . If you anticipate what is go ing to
h appen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast
whenever poss ible -for example when you see
that the next traffic light is red.
Dri vin g and en vironm ent 207
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
" Try and keep well below your car 's maxi-
mum speed .
Acce lerat ing gently reduces fue l consump
tion, eng ine wear, and does not disturb the
environment.
Fuel consumption, exhaust emissions and en
gine noise increase disproportionately at h igh
speeds. If you drive at approximately three
quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed l imit and weather con
ditions perm it.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
" Shut the eng ine off when you are not driv
ing the vehicle .
" Do not warm up the ve hicle by letting the
eng ine run at id le.
The idling phase is automatically reduced for
vehicles with the Start -Stop-System* . It is ef
ficient to switch off the engine in vehicles
without the Sta rt-Stop-System * when stopped
at rai lroad cross ings and long red lig hts . T urn
ing the engine off for jus t 30-40 seconds
saves more fuel than is b urned by s tarting the
engine again.
It takes a long t ime for the engine to warm up
f ully when i t is runn ing a t id le. However, wea r
and noxious emissions are especia lly high
when the engi ne is warming up. So you shou ld
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af
ter start ing . If warning lights sho uld come
on to indicate improper operation, they ..,.

Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded fo r operation away
from paved roads. In situations where slip or a
differential lock ing funct ion is required, the
ESC offroad mode can be act ivated
c> page 197 . Your Audi also has permanent
all-wheel drive in addition .
However, your Aud i is not a pure offroad ve hi
cle . It was not built for driving under extreme
conditions, e .g . for trips that are in the nature
of an expedition .
D riv e only on roads and offro ad sections
which match the des ign of your vehicle and
your abil it ie s as a driver . Ne ver take ri sks!
Before dri ving offroad
- Check the engine oi l level, tire pressure,
coolant leve l, and the fluid level in the w ind
shield washer reservo ir.
- Stow luggage items and other objects in the
lu ggage compartment, and secure them
against slid ing around .
After driv ing offroad
- After trips offroad, remove any twigs and other foreign objects from the grill, the un
derbody and the wheels. Pay specia l atten
t ion to fore ign objects (stones) which have
become lodged in the tire tread.
- Clean the body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license plates.
- Perform a brake check (particu larly after
trave lling through water) .
A WARNING
- Drive especially attentive ly and plan
ahead in difficult road conditions and
w hen offroad . Excess ive speed or incor-
-

rect maneuvers can cause injuries and
damage to the vehicle.
- Always adapt your speed and driving
style to road, offroad, traff ic, and weath
er conditions. Drive especially slowly off
road when your v iew is restricted.
- Please be aware that in ESC offroad
mode, particularly on a smooth and slip
pery road, the wheels may have an in
creased tendency to spin and the vehicle
may break away - danger of skidding!
- Stability is limited in the ESC offroad mode.

Driving tips
On poor road and offroad, there is always on
ly one motto: Plan ahead and drive slowly!
Please observe the following when dr iving
away from paved roads:
• Drive only on roads and offroad sections
wh ich match the design of your vehicle and
your abilities as a dr iver. Never take risks!
• Drive slowly and plan ahead!
• Take into consideration the
ground clear
ance
of your vehicle.
• Activate the
ESC off road mode ~ page 19 7
as needed. •
Use the
hill descent assist¢ page 199
when driving down steep sections on hi lls .
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown
offroad sections, and look o ut for unexpected
obstacles (e.g . potholes, ro cks, tree stumps,
etc.).
To prevent the vehicle from bottoming and
avo id damage to the underbody, you should
drive straig ht across severe bumps in the
ground with only one side o f the ve hicle so
that only two of yo ur whee ls cross the bumps.
Drive briskly through sandy or marshy offroad
sections and do not stop , if at all possible.
Driving through water
Note the follow ing to avoid veh icle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than walk ing speed .
Driving on a slope
If you ever find yourse lf not able to climb a
s lope, do not try to turn around, drive back
down in
reverse. Otherwise, you run the r isk
of tipp ing over.
If the vehicle threatens to tip over when
driving across a slope, you must immediate
ly steer downhill in the direction of the
slope.
Do not park your vehicle on steep s lopes or
grades.
T o red uce the risk of tipping over, drive on
s lopes in the direction of the downward slope
(fall line) -
not crosswise.
A WARNING
-~
After driving through water, mud, slush,
etc ., the brakes may be s low to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re-
store the full braking effect. .,..

212 Trailertowing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
T ra ile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita
ble for your vehicle and trailer and mu st be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
h itch with a removable ball mount. A lways
check with the trai ler h itch manufact urer to
make sure that you are using the correct
hitch.
Do n ot use a bumper hi tch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys
tems . From t ime to time, check that all hitch
mounting bo lts remain securely fastened.
When you are not towing a trailer, remove the
trailer h itch ball mount. This prevents the
h itch from causing damage should your veh i
cle be struck from behind
¢ A .
Traile r brak es
If your tra iler is equipped w ith a braking sys
tem, check to be sure that it conforms to a ll
regulat ions . The trailer hydraulic brake system must not be
direct ly connected to the vehicle's hydraulic
brake system
~ A .
Saf ety ch ain s
Always use safety chains between your veh icle
and the trai le r.
Trail er light s
Trailer lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirror s
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors .
It is important
that you always have clea r vis io n to the rear.
,8. WARNING
- I f a trai ler has electrical brakes p lease
note that these brakes are not activated
by the factory -fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve
h icle. The vehicle was not designed for
these kinds of trailer h itches. The h itch
attachment can fail, caus ing the trailer
to tear loose from the veh icle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance
label on the driver's s ide B-pillar, must
never be exceeded under any c ircumstan
ces. Exceeding the Gross Vehicle Weight
Rating of yo ur vehicle is likely to damage
your vehicle, and such damage will not
be covered by yo ur Limited New Ve hicle
Warranty . Exceeding the Gross Vehicle
Weight Rating will a lso change the per
formance and handling characteristics of
your veh icle, wh ich could cause a crash
resulting in serious injury or death.

Fig. 190 Permit ted ball position of the trailer hitch
Trailer towing weights
With a factory-installed or an aftermarket
trailer hitch, the maximum permissible trailer
weight is 4,400 lbs (2,000 kg). The maximum permissible unbraked trailer weight is 1,650
lbs (750 kg) . These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
For best vehicle handling under these
changed conditions, adjust the trailer load so
that the tongue load is at the maximum al
lowable or slightly lower . You can get an ap
proximation of the tongue load with a bath
room scale or you can measure the load at a
trucking company or weighing station.
With a
factory-installed or an aftermarket
trailer hitch, the maximum permissible load
on the ball hitch may not exceed 440 lbs
(200 kg).
It is recommended to use the maxi
mum permissible load.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢.&. in Driving instructions on page 214.
Ball mount
The trailer hitch may only be used with suita
ble ball mount and ball¢
fig. 190. Installa
tion of the hitch ball must be carried out in ac-
Trailer towing 213
cordance with the manufacturer's instruc
tions.
Engine cooling system
Towing a trailer makes the engine work hard
er .
It is important that the cooling system's
performance is up to the additional load.
Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the tire pressure label. The tire
pressure label is located on the driver's side B
pillar. Inflate trailer tires to trailer and tire
manufacturers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con
nected from the trailer to the hitch on the ve
hicle. Leave enough slack in the chains to per
mit turning corners. When you install safety
chains, make sure they will not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following :
.,. Do not tow a loaded trailer when your car it
self is not loaded .
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.
