ponents 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 com
partment .
- Never spill fluids on hot engine compo
nents. 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 .
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- 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 imme
diately 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 of automatic transmission
to P (Park).
Checking and Filling
-Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting 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.
- Minimize exposure to emission and chemi
cal hazards

A WARNING
California Proposition 65 Warning:
- Engine exhaust , some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali
fornia to cause cancer and birth defects and
reproductive harm. In addition, certain flu
ids contained in vehicles and certain prod
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
- Battery posts, terminals and related acces
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms .
Wash hands after handling .
(I) Note
When adding fluids, always make sure that
they are poured into the proper container or
filler opening, otherwise serious damage to
vehicle systems will occur.
@) For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If you
see spots from oil or other vehicle fluids, have
your vehicle inspected by an authorized Audi dealer.

.,. Read the engine coolant level from the coolant
expansion tank
c> fig . 200, c> page 222,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark

be s light ly above the
"MAX " marking .
T he location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion
i=> page 222.
To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 29 wi ll
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec
tr ic coolant level sensor, we still recommend you
check the coolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
syst em. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant .
In a
sealed system, losses can occur only if the
boiling point of the coo lant is exceeded as a re
sult of overheat ing .
(D Note
Do not add any type of radiator leak sealant
to your veh icle's engine coolant. Adding radia
tor repair fluid may adversely affect the func
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .
Adding coolant
Be very careful when adding engine coolant.

A WARNING
-- The cooling system is under pressure and

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al
so damage important parts of the
vehicle and can lead to sudden

tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas
sengers also depends on making
sure that load limits are not ex
ceeded. Vehicle load includes ev
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi
cle's
Gross Vehicle Weight Rat
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ..,.

plus maximum load. The maxi
mum load includes the number of
passengers that the vehicle is in
tended to carry ("seating capaci
ty") with an assumed weight of
150 lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ
ed as part of the vehicle load .
The
Gross A xle Weight Rating
("GAWR") is the maximum load
that can be appl ied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi
c le Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a tra iler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas
sengers in the vehicle or passen
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle We ight Rating
and the Gross Axle Weight Rating

are listed on the safety compli
ance sticker label located on the

¢ page 244,
fig . 206.
_& WAR NING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per
sonal in jury, and even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to
tal load being transported -
including the weight of a trail
er hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating .
