Closing the engine hood
- Pull the hood down until the pressure from the struts is
reduced.
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage=:> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area=>& .
& WARNING
To help avoid injury, before you check anything under the hood:
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
Safety first
& WARNING (continued)
• Move selector lever to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire. • Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch:
-Ignition cables
- Other components of the high voltage electronic ignition
system.
• If you must perform a check or repair with the engine running:
- First, fully apply the parking brake, move selector lever to
"P" (Park). .,

long hair from getting caught in the radiator fan, V-belts or
other moving parts, or from contacting hot parts. Tie back hair
before starting, and do not wear clothing that will hang or
droop into the engine.

Brake fluid
Checking brake fluid level
The brake flu id l eve l can be checke d with a quick gl ance .
Fig . 238 E ngine
compa rtment : Brake
fluid rese rvoir
Before you check a nyt hin g i n th e eng ine compa rtment ,
always read and heed all WARNINGS=> & in " Working in
the e ng ine compartmen t" on
page 301 .
-Read the brake fluid level from t he bra ke flu id reservoir
=> fig. 238 . T he bra ke fluid leve l must be between the
" MIN " and "MAX" markings.
Th e brake fl uid rese rvoir is located at the rear partition of t he engine
compartment on the left side=>
page 302.
The fluid level may drop slightly after some time due to the auto­
m atic adjus tment o f th e brake pads. This is no t ca use for alarm .
If the brake fluid level falls
considerably below the "MIN" mark, t he
brake warn ing/i nd icator lig ht ( U.S. models :
BRAKE, Canadian mode ls:

[ i ] Tips
T he b rake fl uid reservoir is located unde rneath t he cover. •
Changing brake fluid
Have the b rake fluid chan ged by an exp eri enc ed t echni ­
cian.
B ra ke flui d absorbs mois ture fro m th e air . If the w ater con ten t in the
brake fl uid is too high, corros io n in th e brake system may result afte r
a p eriod of time. The boil ing po int of the br ake fl uid will also de cre as e
cons iderab ly and decr ease brak ing performa nce.
Th erefo re, the brake fl uid m ust be changed
every two years. Always
use new br ake fluid w hich conforms to Federal Motor Veh icle Stan­
dard "FMVSS 1 16 DOT
4" .
The b rake fl uid reservo ir can be diffi cult to rea ch, there fore, we
recommend that you have the brake fluid c hanged by your author ized
Audi dealer. Your dea ler has the correct tools, the rig ht b rake f luid
and the k now-how to do t his for you .
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the rea ch of children!
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions:
-Use only brake fluid that meets SAE specification
J 1703 and
conforms to Federal Motor Vehicle Standard 116. Alway s check
with your authorized Audi dealer to make sure you are using
the correct brake fluid. The correct type of brake fluid is also indicated on the brake fluid reservoir .
& WARNING (co ntinued )
-The brake fluid must be new. Heavy use of the brakes can
cause a vapor lock if the brake fluid is left in the system too
long . This can seriously affect the efficiency of the brakes as
well as your safety . This could result in an accident.

Wheel balancing
The w heels on new ve hicl es a re bala nced. However, v ario us sit uatio ns
dur ing everyday driving can cause them to become unba lanced,
re su lt ing in vibra tions yo u can usually fee l throug h the stee rin g

Unbalanced whee ls mus t be rebalanced to avoid excessive wear on
s t eer ing, suspension and t ir e s. A wheel must also b e rebalanced
w hen a new tire is installed.
Safety first
Incorrect wheel alignment
Incorrec t wheel a lignment can c ause excessive t ire wear, im pair ing
t he sa fety o f the ve hicle . If t ires s how exc essive wear, hav e the wheel
alignment checked by an author ized A udi dealer o r qualifie d wo rk ­
shop.
All Wheel Drive
Vehicles with quattro ® must a lways have tires of the same s ize,
constr uctio n an d trea d type . For details see ;:::,
page 262.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear ind icators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil , gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged

tire failure and loss of vehicle control. •
