The steering wheel can be adjusted even when
the ign ition is turned off. For vehicles wi th
seat memory, the individual positions for the
steering wheel can be stored a long with the
seat position .
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
-Adjust the steer ing whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering whee l
so that there is a m inimum of 10 inches
(25 cm) between your chest and the
steer ing whee l
r::;,page 145, fig . 162 . If
you cannot maintain th is m inimum dis­
tance, the a irbag system cannot protect
you properly.
- If physical limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equ ipment is ava ilable .
- If the steer ing whee l is aligned with your

146 Driving Safely
• Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see
¢ page 63.
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag de­
ploys.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver 's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air ­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and
make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving . Your seat may move unexpect­
edly and you could lose control of the ve­
hicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in- jury due to incorrect positioning of the
safety belt and improper seating posi­
tion.
- Children must always ride in child safety
seats ¢
page 186. Special precautions
apply when installing a child safety seat
on the front passenger seat¢
page 162 .
Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving .
For your own safety and to reduce the risk of
injury in the event of an accident, we recom ­
mend that you adjust the seat for the front
passenger to the following position :
• Move the front passenger seat back as far
as possible . There must be a minimum of
10 inches (25 cm) between the breastbone
and the instrument panel¢,&. .
• Adjust the angle of the seatback so that it is
in an upright position and your back comes
in full contact with it whenever the vehicle is
moving.
• Applies to vehicles with adjustable head re­
straints: Adjust the head restraint so the up­
per edge is as even as possible with the top
of your head. If tha t is not possible, try to
adjust the head restraint so that it is as
close to this position as possible.
• Keep both feet flat on the floor in front of
the front passenger seat.
• Fasten and wear safety belts correctly
¢page 157.
For detailed information on how to adjust the
front passenger's seat, see
¢ page 61.
A WARNING
-
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of
serious personal injury:

A WARNING
-
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow . Fuel spray and overflowing fuel can
cause a fire .
- Never use a cellular telephone while re­
fueling . The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle white re­
fueling .
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static e lectricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open f lame any­
where in or near your veh icle when refu­
eling or filling a portab le fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable

When the engine is warm, the level may be
slightly above the
"MAX" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢ page 239.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System ¢page
31 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing 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 coolant is exceeded as
a result of overheating.
& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap­
plying light, downward pressure on the
top of the cap.
- To avoid being burned, do not spill anti­ freeze or coolant on the exhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
Checking and filling 245
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function 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.
Before you check anything in the engine com­
partment,
always read and heed all WARN­

.. Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications ¢ page
244, Coolant.
Even in an emergency, if coolant addi-
tive G12++, G12+ or G12 is
not available, do
not use a different additive. Use plain water
instead until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible.
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.

sca lding from hot coolant by following
these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by cover ing
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying lig ht, downwa rd pressure on
the top of the cap.
- To avo id being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en­
gine coolant can catch f ire.
- Antifreeze is poisonous . Always store an­
tifreeze in its or iginal container and we ll
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".
@ Note
- Coolant pollutes the environment and
could cause an engine fire . Excess coo l­
ant will be forced out through the pres­
sure relief 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
c::> page 244 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained 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
T he 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* switches on
and off depend ing on coolant temperature
and other vehicle operat ing condit ions .
After yo u sw itch the engine off, the auxiliary
f an can continue running for up to 10 minutes
- even with the ignit ion off. It can even switch
on again later by itself
c::> &., if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in i ntense sunlight.
_& 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 switches on au­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops .

Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the t ires on your vehicle .
It is importan t to check the tire pressu re when
the t ires a re cold .
- Read the requ ired ti re p ressure from the tire
pressure label. On USA veh icles, the t ire
pressure label is located on the drive r's side
B-pi llar . On Canada vehicles, the tire pres ­
s u re label is located either on the driver's
s ide B-pi llar or inside the fue l filler flap . The
t ire press ure label lists the recommended
cold tire inflation pressures for the veh icle
at its max imum capacity weight and the
t ires that were on your vehicle at the time it
was manufactured . Fo r recommended t ire
pressures fo r normal load condit ions, please
see chapter
9page 256.
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressu re ga uge on the valve .
- The tire pressures should only be checked
and adjusted when the tires a re cold . The
s li ghtly raised p ressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you a re
c a rrying.
- Re install the valve stem cap o n the valve .
When should I check the ti re pres sure ?
The correct tire pressure is espec ially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways befo re start ing a journey . Do not
forget to check the tire pressure for the spare
wheel.
When should I ad ju st the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition , you must then in it i­
alize the new tire pressures in the tire pres­
sure mon itor ing system*
