' 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 per­
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
~ ,&. .
/n.. WARNING
To help avoid injury, before you check any­
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- Apply the parking brake.
- 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
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­

- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the engine is still warm . The cool­
ant system is pressurized and hot cool­
ant 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 electri­
cal system is necessary:

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
Accessory weight
means the comb ined weight (in excess of
those standard items which may be rep laced)
of automatic transmission, power steering, power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory -installed equip ­
ment (whether installed or not) .
Aspect ratio
means the ratio of the he ight to the w idth of
the tire in percent. Numbers of 55 or lower in­
dicate a low sidewall for improved steering re­
sponse and better overall handling on dry
pavement.
Bead
means the part of the tire that is made of
steel wires, wrapped o r reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a breakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Cold tire inflation pressure
means the tire pressure recommended by the
vehicle manufacturer for a tire of a designated size that has not been driven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted. -
If you notice unusual vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
Curb weight
means the weight of a motor vehicle w ith
standard equipment including the maximum
capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optiona l
equipment.
Extra load tire
means a t ire design to operate at h igher loads
and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"R F" on the sidewall .
Gross Axle Weight Rating ( "GAWR ")
means the load-carrying capacity of a s ingle
axle system, measured at the tire-ground in­
terfaces .
Gross Vehicle Weight Rating ("GVWR")
means the maximum total loaded weight of
the vehicle.
Groove
means the space between two adjacent tread
ribs .
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be­
cause it is not required by law.
Maximum load rating
means the load rating for a tire at the maxi­
mum permissib le inflation pressure for that
tire.

The speed rating letter code (c::> page 23 7) is
on the side wall of the tire
c::> page 246.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.

Tires and wheels
Snow chains
Snow chains may be fitted only to the front
wheels , and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch
(10,S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (]) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING ,..__
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so. ..,.

.&, WARNING
- T he ac tual Gross Axle Weight Rat ing at
the front and rear axles shou ld not ex­
ceed the permiss ible weights, and their
combination must not exceed the Gross
Vehicle Weight Rat ing .
- Exceeding permissib le weight ratings can
result in vehicle damage, accidents and
personal injury.
CD Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage) . When
transporting a heavy load in the luggage
compartment, carry the load as near to
the rear axle as possib le so that the veh i­
cle's handling is not impa ired.
- Do not exceed the maximum permissible
axle loads or the max imum gross vehicle
weight . Always remember that the vehi­
cle's handling will be affected by the ex­
tra load. Therefore, adjust you r speed ac ­
cord ingly.
- Always observe loca l regu lations.
