Brake lining w ear sta tus
Brake lining we ar may be che cked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the wheel may be remove d for this in­
spection
c> page 244, Changing a wheel.
.&_ WARNING
- New brake pads do n't have the best sto p­
ping power and must be "broken-in" dur­
ing the init ial 100 to 1 50 m iles (150 to
200 k ilometers) of normal city driving.
T he break-in period can be considerably
longer for veh icles with ceram ic br ake ro­
tors*. You can compensate for this by pressing the brake pedal more firmly.
T his also applies later when new pads are
installed .
- You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
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 ofte n. This cou ld cause the
brakes to get hot and d imin ish b raking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not inte nd
t o brake. Th is may cause the b rakes to
overheat, prema ture wear and inc reased
stopping distance .
- Under certa in climat ic and operating
conditions 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
for a test. Brakes will dry and ice coat­ ings will be cleaned off after a few ca re­
ful brake applications.
- Driv ing fo r an extended pe riod of time on
salt-covered roads w ithout using you r
Intellig ent technolog y 175
brakes can a lso affect braking efficiency .
Clean off accum ulated 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 obstruct­
ed. Otherw ise the brake system could
overheat reducing t he effectiveness of
the entire brake system.
- Failure of one b rake circuit will impa ir
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle and have it towed to the near­
est a utho rized Audi dea le r or q ualified
workshop.
- Never let the vehi cle roll to a stop with
the engine shut off.
- If the b ra ke booste r is no t working, the
brake peda l must be p ressed considera­
b ly harder to make up for the lack of
booster assistance .

180 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Warming up and
cooling down
-
By carefully warming up and cooling down
your ve hicle, you can he lp ensure that it is not
overstressed unnecessarily dur ing sporty driv ­
ing.
When warming up, the vehicle is d riven at a
maximum engine speed of 6000 RPM in order
to raise the engine oi l temperature to a mini ­
mum of 140
°F (60 °(). The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can contin ue to run in your ve­
h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the ex ha ust system, and
the transm ission all become extremely hot.
B efore you park the vehicle, you shou ld drive it for a few miles/kilometers at
light load in
the low rpm range to allow it to cool down.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline c:> page 190,
Fuel supply.
.. Never run the tank down all the way to emp­
ty .
.. Never put too much moto r oil in your engine
c:> page 199, 't::71 Adding engine oil .
.. Never try to p ush- or tow -sta rt yo ur vehicle.
The catalytic converter is an efficient "clean­
up" device bu ilt into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts i n t he exh aust gas be­
f ore they are re lease d into the atmosphere.
T he exclusive use of unleaded fue l is critica lly
impor tant for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engi ne.
8_ WARNING
- T he temperature of the exhaus t system
is high, both when driving and after stop ­
p ing the engine.
- Never touch the exhaus t tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle i n
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ver ter or heat shields . Dur ing driv ing, the
substance used for undercoating could
overheat and cause a fire.

important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your
passengers also depends on
making sure that load limits are not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle.
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum
load. The maximum load in­
cludes the number of passen­
gers that the vehicle is intend­
ed to carry ("seating capacity")
with an assumed weight of 150 lbs . (68 kg) for each pas­
senger at a designated seating
position and the total weight of
any luggage in the vehicle. If
you tow a trailer, the weight of
the trailer hitch and the tongue
weight of the loaded trailer
Tires and wheels 225
must be included as part of the
vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of
the vehicle's two axles.
The Gross Vehicle Weight Rat­ ing and the Gross Axle Weight
Rating are listed on the safety
compliance sticker label locat­
ed on the driver's side 8-pillar.
Your Audi has 4 seating posi­
tions, 2 in the front and 2 in the rear for total seating capacity
of 4. Each seating position has
a seat belt¢ page 123, Safety
belts.
The fact that there is an upper limit to your vehicle's Gross Ve­
hicle Weight Rating means that
the total weight of whatever is being carried in the vehicle (in­
cluding the weight of a trailer hitch and the tongue weight of
the loaded trailer) is limited.
The more passengers in the ve­ hicle or passengers who are
heavier than the standard
weights assumed mean that less weight can be carried as
luggage.

3. Subtract the combined weight of the driver and pas­sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
.:::> page 217, fig. 182.
4. The resulting figure equals
the available amount of car­ go and luggage load capaci ­
ty . For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs . passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-750
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle .

(.:::> page 230, fig. 186) to de­
termine the designated load
rating for a specific tire.
Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure
and driving style.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to carry the starter current
safely. Refer to the manufacturer's specifica­
tions.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 255
-A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery.
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery. Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::;,page 195.
(D Note
-Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­ tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,. •

control unit.
- Check that all screw plugs on the battery
ce lls are screwed in firmly . If not, tighten
plugs p rior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­
necting a jumper cable as described
above applies spec ifically to the case of
your vehicle be ing jump started. When
you are givi ng a jump start to another ve­
hicle, do
not connect the negat ive( -) ca­
ble to the negat ive( -) term inal on the
discharged battery @¢
