Engine coolant temperature gauge
The engine coo la nt gauge ¢ page 10 , fig. 3@
only works when the ign ition is on. To prevent
damage to your e ngine, please note the fo l­
l owing important points:
Engine cold
As long as the nee dle rem ains a t the left end
of the gauge, the engine s till h as not reac hed
its operating temperat ure. Avoid high engine
speeds, heavy engine loads and heavy throt­
tle.
Normal temperature
W hen the engine has re ache d its ope rat ing
temperature, the need le w ill move into the
mid dle of t he gauge and rema in there .
If the
engine is working hard at high outside tem ­
peratures, the needle may turn fu rther to the
right. This is no cause for concern as long as
the . warning light in the instrument cluster
does not illuminate .
When the. warning light sta rts to flash,
th is can mean one of two things: either the
coolant
temperature is too high, o r the coo l­
ant
level is too low ¢ page 17 .
A WARNING
--Always obs erv e th e war ning in

Adjusting the steering wheel column
The steering wheel position can be continu­
ously adjusted in height and distance .
Fig. 80 Lever under the steer ing colu mn
~ Push the lever Q fig. 80 -Arrow- ¢&_ .
~ Move the steer ing whee l to the desired posi ­
tion.
~ Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­ ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detai led informat ion on how to adjust the
driver's seat, see
Q page 61.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering wheel column only
when the veh icle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering wheel
so that there is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel¢
page 92, fig . 99. If
you can not maintain this min imum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 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 wheel is aligned with your
face, the supplemental dr iver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steer ing whee l is aligned with your
chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o' clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never ho ld the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub . Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

A WARNING
-Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and

~ 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
c:> page 60.
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it deploys. 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 adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and
the lower part of the instrument panel.
- 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 in­
flates
- 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-
Driving Safely 93
ed ly 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 seats
c:> page 129 . Special precautions apply
when installing a child seat on the front passenger seat
c:> page 108.
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 :
~ 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.
~ Adjust the head restraint so that the upper
edge is as even w ith the top of your head as
possible but not lower than eye level and so
that it is as close to the back of your head as
possible
c:> page 94.
~ Keep both feet flat on the floor in front of
the front passenger seat .
~ Fasten and wear safety belts correctly
c:> page 103.
For detailed information on how to adjust the
front passenger's seat, see
c:> page 59 .
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:

Before you check anything in the engine com­
partment,
a lway s read and he ed a ll WARN­
ING S o .A in Working in the engine compart­
ment on page 164.
., Park your vehicle on a level surface.
., Switch the ign ition
off .
., Read the coolant level at the coolant expan­
sion tank
opage 166, fig . 128. With a cold
engi ne, it must be above the "min" mark.
With a hot engine, it can be a l ittle above
the indicated range.
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration
o page 166.
To obtain an accurate read ing, the eng ine
must be sw itched
off.
The expans ion 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
opage 17will
illum inate until you add coolant and the level
has been restored to normal. Even thoug h
there is an electric coolant level sensor, we
still recommend you check the coolant leve l
from time to t ime.
Coolant lo ss
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 dea
ler .
It is not
enough merely to add coo lant .
In a
seal ed system, losses can occu r on ly if
the boi ling po int o f the coo lan t is exceeded as
a res ult of overheating.
(D Note
Do n ot add any type o f radiator leak se al­
ant to your veh icle's engine coo lant. Add ­
i ng radiator repa ir fl uid may adverse ly af ­
fect the functio n and performance of you r
cooling system and could result in damage
not cove red by your New Veh icle l imited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com ­
partment,
a lways read and heed all WARN­

not
use a different add itive . In an emergency use
plain water until you can get the co rrect addi­
t ive and can resto re the correct ratio. This
sho uld be done as soon as poss ib le.

If you have lost a consi derable amount of
coolant, then you should add co ld antifreeze
and cold water only when the engine is co ld .
Always use
new engine coolant when refi lling.
D o not fi ll coolant above the "MAX " mark . Ex­
cess coolant will be forced out th rough the

- If you drain the coolant , it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
@ Note
- Do not add coolant if the expansion tank
i s empty . Ai r could enter the cooling sys­
tem and damage the engine. If this is
the case, do not continue driving. Seek professional assistance.
- Coolant po llutes the env ironment and
could cause a n engine fire. Excess coo l­
ant wi ll be f orced out through the pres­
su re re lief valve in the cap when the en ­
gine becomes hot.

, Radiator fan
The radiator fan switches on automatically by
itself .
The electric radiator fan is controlled by ther­
moswitches that switch on and
off depending
on coo lant and eng ine compartment tempera­
tures.
An a uxiliary electric radiato r fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ion conditions .
After yo u switch the eng ine off, the aux iliary
f an can continu e running for up to 10 m inut es
- even with the ignition off. It can even switch
on again later by itself¢ & , if
- t he temperatu re of the engine coo lant rises
due to the hea t build -up from the engine in
the engine compa rtment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlig ht.
A WARNING ~
- To reduce the risk of persona l in ju ry nev-
er touch the radiator fan .
- The a uxiliary electric fan is tempe rat ure
contro lled and can switch on suddenly
even when the engine is not running.
- The a uxiliary radiator fa n sw itches on a u­
tomatically when the engine coo lant
reaches a certai n temperature and will
continue to ru n until the coo lant temper­
ature drops. •
