-To reduce the r isk 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 ca re­
fully opening the hood .
- Keep children away from the engine com ­
partment.
- Never spill flu ids on hot engine compo­
nents. They can cause a fire .
- Never touch the radiator fan. The aux ili­
ary e lectr ic fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thic k rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of bu rns.
- If wo rk on the fuel system or the electri­
cal sys tem is ne cessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
partment co uld start a fire.
- Keep an approved fire extinguisher im­
mediately ava ilable.
- To avoid electrical s hock and persona l in­
jury 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 repa ir
with the engine running:
- Fir st, fully apply the parking brake,
move se lector lever of a utomatic trans-

- Always use extreme caution to prevent
clothing, jewe lry, or long hair from get­
ting caught in the radiator fan, V-be lts
or other moving parts, or from contact­ i ng hot parts . Tie back hair before
starting, and do not wear clothing that
will hang o r droop into the engine .
- Minimize exposure to emission and
chemical hazards~&. .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its const ituents,
a nd certain vehicle components contain
or emit chemicals known to the State of
Ca lifornia to cause cance r and birth de­
fects and reproductive harm. In addition, certain fl uids contained in veh icles and
certain products of component wear con­
tain or emit chemica ls known to the
State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories conta in lead and lead com­
pounds, chemicals known to the State of

tive harms. Wash hands afte r handling.
Q) Note
When adding f lu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur .
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regular ly . If

242 Tires and wheels
-Only when all tires on the
vehicle are filled to the cor­ rect pressure, the tire
pressure monitoring sys­
tem* can work correctly.
-The use of incorrect tire
pressure values can lead to
accidents or other damage.
Therefore it is essential that
the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system*.
-Always inflate tires to the
recommended and correct
tire pressure before driving off.
-Driving with underinflated
tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­
loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too
low or too high, the tires
will wear prematurely and the vehicle will not handle
well.
-If the tire is not flat and you
do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­
ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage

Your vehicle is equipped with all whee l drive,
this will improve traction during winter driv­ ing, even with the standard tires. However, we
strongly recommend that you a lways equ ip a ll
four wheels on your veh icle w ith correctly fit­
ted wi nte r tires or all -season tires, when w in ­
ter road conditions are expected. This also im­
p roves the vehicle 's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow .
W inter tire s (snow t ires) must always be fitted
on all four wheels.
Ask your authorized Audi dea ler o r qualified
workshop for permitted
w inter t ire sizes. Use
only radia l winter tires .
Winte r ti res lose thei r effectiveness when the
tread is worn down to a depth of
0 .15 7 inch
(4 mm) .
On ly drive with winter tires under winter con­
d itions. Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45
°F (7 °().
If yo u have a flat tire, see notes on spare
wheel ¢ page 248 .
Pl ease always remembe r th at w inte r ti res may
have a lower speed rating tha n the t ires origi­
n all y ins talled on your veh icle at the t ime i t
was manufactured . Please see ¢ page 250,
Speed roting (letter code) for a Listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code( ¢ page 232) is
on the side wall of the tire ¢ page 248.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed befo re driving off . Never drive faster
than the speed permitted for your specific
w inte r tir es . This will cause damage to the
ti res leading to an ac cident and se rious
pe rsonal i njury to you and yo ur p assen­
gers .

A WARNING
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause t ire fail ure in­

A WARNING
=
A lways ad just yo ur driving to t he roa d and
traffic conditions. Never let the good ac­
celeration of the winter tires and a ll 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
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions.
@ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
Snow cha ins may be fitted only to the fro nt
whee ls, and on ly to certain tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow chains can be used.
The snow chains must have low-p rofile links
and must not be th icker than
