pressure relief valve in the cap when the en ­
gine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps.
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- T urn the cap slowly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avo id being burned, do not sp ill an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be caught and safely stored in a proper con­
tainer clear ly marked "poison".
- Coolant pollutes the environment and
could cause an engine fire. Excess coo l­
ant will be forced out through the pres­
sure re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze~
page 238 must be re­
stored as soon as possib le.
@ For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while observ­
ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is driven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
An auxiliary electric radiator fan* sw itches on
and off depending on coolant temperature
and other vehicle operat ing condit ions.
After you switch the engine off, the aux iliary
fan can continue running for up to 10 m inutes
- even w ith the ignition off. It can even switc h
on again later by itself
c> &. , if
- the temperature of the engine coo lant r ises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certain temperature and w ill
con tinue to run until the coolant tempe r­
a ture drops.

248 Tire s and whee ls
- 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
(D Note
Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Acces sory weight
means the comb ined we ight (in excess of
those standard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
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 ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typica
l in those seasons. Audi recommends
using winter tires during the winter
months. Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very cold tem­ peratures, cracks ca n form on the tread
bars, resulting in permanent tire damage
that can cause loud driving no ise and un­
balanced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pre ssure
means the t ire p ressure recommended by the
vehicle manufacturer fo r a tire of a des ignated
s ize that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted.
Curb weight
means the we ight of a motor ve hicle w ith
standard equipment including the max imum
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 higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -carry ing capacity of a s ingle
axle system , measured at the tire-ground in­
terfaces.
Gr oss Vehicle Weight Rating ("GVWR ")
means the maximum total loaded we ight of
t h e vehi cle. .,.
