few careful brake applications should dry off
the brake pads or remove any ice coatings.
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

Q & .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
f irmly a few times from a moderately high
speed

Faults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circuits may have failed
Q & .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.

WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission 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 diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa
ter, driving in heavy rain or after washing
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 care
ful brake applications.
- 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
flow to the front brakes is not obstruct
ed. Otherwise the brake system could
overheat 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 Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
~
different weight distribution. Safety, perform
ance and economy w ill greatly depend on how
carefu lly you load yo ur trailer and operate
your rig.
B efore you actua lly tow your trailer, practice
turning, stopping and backing up in a n area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your veh icle- trailer comb inat ion behaves and
responds .
Backing up is d ifficu lt and requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer .
M aintain a g reater distance between your ve
hi cle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than norma l
turn ing radius.
When passing, remember that yo u cannot ac
celerate as fast as you normally would be
cause of the added load . Make s ure you have
e nough roo m to pass . After passing, allow
p lenty of room fo r your tra ile r befor e chang
in g la nes aga in.
Avoid jerky sta rts, sharp turns or rapid lane
cha nges.
(D Tips
- Do not tow a tra iler during the break- in
period of you r vehicle.
- If you t ow a trailer, your A udi may re
quire more frequent maintenance due to

Parking on a slope
Do not park on a slope with a trailer. If i t can
not be avoided, do so only after doing the fol
lowing:
When parking:
.. Apply the foot b rake .
.. Have someone place chocks under both the
vehicle and the trailer wheels.

214 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 204.
Engine compartment
Be especially careful when cleaning the en
gine compartment.
Always switch off the ignition before clean
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be tho roughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro sion treatment is a lmost always removed as
well. It is therefore essential to have a long lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart
ment, be sure to read the information
c> page 220.
-Before reach ing into the front panel, al
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly -even when the ignition is
off.
- Do not wash, wax or dry the engine with
the engine running . Moving or hot parts
could injure you.
- Do not clean the underside of the chas
sis, fenders, wheel covers, or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
-Always read and heed all WARNINGS and
other information
c> page 204.
236 Tires and wheels
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
Glossary of tire and loading terminology

General
This chapter is intended for trained emer
gency crews and working personnel who
have the necessary tools and equipment to
perform these ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles w ith an automatic transmission
cannot be started by pus hing o r tow ing.
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 jumpe r cables to start the en
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe
ly. Refer to the manufacturer's specif ications.
Use only jumper cables with
insulated termi
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean
ing over the battery whenever possible.
- A discharged battery can freeze at tem
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, 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 vo ltage 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 d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in
jury.
- Never charge a frozen batte ry. 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 batter ies of different voltage or
substantially different capacity (Ah) rat
ing may cause an exp losion and injury.
The capacity (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 a ll
WARNINGS¢
page 214, Engine com
partment.
«I) Note
-Applying a higher voltage booster bat
tery will cause expensive damage to sen
sitive electronic components, such as
contro l units, relays, rad io, 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. ..,_
2 70 Emergency situations
-When connecting jumper cables, make
sure that they cannot get caught in any
moving parts in the engine compart
ment.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS c:>
page 214, Engine com
partment.
(D Note
Improper hook-up of jumper cables can ru
in the generator.
-Always connect POSITIVE(+) to POSI TIVE(+), and NEGATIVE( -) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that all screw plugs on the battery
cells are screwed in firmly . If not, tighten
plugs prior to connecting clamp on nega
tive battery terminal.
- Please note that the procedure for con
necting a jumper cable as described
above applies specifically to the case of
you r vehicle being jump started. When
you are giving a jump start to another ve
hicle, do
not connect the negative(-) ca
ble to the negative(-) terminal on the
discharged battery@c:>
fig. 201. In
stead, securely connect the negative(-)
cable to either a solid metal component
that is firmly bolted to the engine block
or to the engine block itself. If the bat
te ry that is being charged does not vent
to the outside, escaping battery gas
could ignite and explode!
