Safety belts
Only well-maintained safety belts work reliably when
needed.
Heavily soiled safety belts may not retract properly.
- Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condit ion of your safety belts
regularly.
& WARNING
Damaged safety belts can break in a crash .
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and the information
=:> page 230. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine :::::, &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts.
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
I f the engine compartment is cleaned at any time with grease
removing solutions
21 , or if you have the engine washed, the anti­
corrosion treatment is almost 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 compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information :::::,
page 242. .,.,
21 Use only the correct cleaning solutions. Never use gasoline or diesel fuel.

Closing the engine hood
-Pull t he hood down until the pressure from the strut is
reduced.
- Let t he hood
drop down and latch in place. Do not try to
push it shut;
it may fai l 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
~ 6 .
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral.
• 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:

Wheel change
Before changing a wheel
Follow these points for your own and your passenger's
safety when replacing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop => & .
- All passengers should leave the car and move to a safe
location (for instance, behind the guardrail)=>& .
- Apply the parking brake firmly=>&.
- Move selector lever to position Pon an automatic trans-
mission; put manual transmission in first gear =>& .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the tool case and the spare tire=>
page 290 out of
the luggage compartment.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flasher on and use other warning devices to alert other motorists .
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the roadway and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed. When one
front wheel is lifted off the ground, placing the Automatic Trans­
mission in "P" (Park), or engaging a gear in a manual transmission
will
not prevent the vehicle from moving .
• Before you change a wheel, be sure the ground is level and firm.
If necessary, use a sturdy board under the jack.
• After installing the spare wheel, make sure that you remount
the flat tire/wheel in its storage area properly and tighten the
knurled retaining screw securely. •
Changing a wheel
When you change a wheel, follow the sequence described
below step-by -step and exactly in that order.
1. Remove the decorative wheel cover*. For more details
see also =>
page 294, "Decorative wheel covers" or
=>
page 295, "Wheels with cap-covered wheel bolts".
2. Loosen the wheel bolts=>
