Engine coolant temperature gauge
The engine coolant gauge ¢ page 10, fig. 3 CD
on ly works when t he ignition is on. To prevent
damage to your engine, please note the follow­
ing important points :
Engine cold
If the needle is at or close to the bottom o f the
gauge, the engine has not yet reached its operat­
i ng temperature. Avo id high engine speeds,
heavy engine loads, and heavy thrott le applica­
tions .
Normal temperature
When the engine has reached its operating tem­
perature, the needle will move to the middle of
the ga uge and rema in there. I f the engine is
working hard at hig h outs ide temperatures, t he
needle may move higher on the gauge. This is not
a cause for concern as long as the. warning
li ght i n the inst ru m en t cluste r display does not il-
l u m inat e. .,,.

Warning light in th e instrument clus ter
di splay
If the . warning light in the instrument cluster
display flashes , this can mean one of two th ings:
either the coolant
t emperature is too high, or the
coolan t
level is too low 9 page 29.
If the needle is well in the upper area of the
gauge, the coo lant temperature is too high.
S top
the veh icle , switc h the engin e off, and allo w i t
to coo l.
If the warning light comes on again after
driving a short distance , contact an authorized
Aud i dealer or other q ualified workshop .
..&, WARNING
-Always observe the warni ng i n 9 page 221,
before opening the hood and chec king the
engine coolan t level.
- Never open the engine hood if you see o r
hear steam, or if you see engine coolant
dr ipping from the engine compartmen t. You
cou ld burn yourself . Let the engine cool off
first so that you cannot hear o r see any
steam or engine coo lant.
CD Note
- M ount ing additional lights or accesso ries in
front of the air inlets red uces the cooling ef ­
fect of the radiator . At high outside temper ­
atures or high engine load, the eng ine could
overheat .
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving . If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author ­
i zed Audi dealer for assistance .
Tachometer (engine rev counter )
The tachometer indicates the engine RPM (revo ­
lutions per minutes) .
If engine RPM drops below 1,500 , you should
downshift to the next lower gear. The red area at
~ the end of the scale indicates max imum perm is -co
~ sible eng ine RPM after the break- in period . Be-
:;, fore reach ing th is area, move the selector lever to

Warm and cold
Warm and cold Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It
is the most effective when the windows and pan­
oramic sliding sunroof* are closed . If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling proc ess.
In all heating mode functions except
defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensation from the cooling system can drip
and form a puddle of water under the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Advisor for advice.
Key coded settings
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .
.8, WARNING
Reduced visibility is dangerous and can cause
accidents.
- For safe driving it is very important that all
windows be free of ice, snow and condensa­
tion.
80
- Completely familiarize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­
ing and ventilation system . The washer solu­
tion may freeze on the windshield and re­
duce visibility .
(D Note
-If you suspect that the air conditioner has
been damaged, switch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repairs to the Audi air conditioner require
special technical knowledge and special
tools. Contact an authorized Audi dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
-Keep the air intake slots (in front of the
windshield) free from ice, snow and debris
in order to maintain the proper function of
the climate control system.
- The energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- The air flowing out of the vents and
throughout the vehicle's entire interior is
discharged at the rear of the vehicle. Make
sure that the outlet slots are not covered by clothing, etc.

Driving
Starting the vehicle with the emergency
key
You can use the emergency key as an ignition key
in an emergency.

Steering lock
The steering locks when you remove the ignition
key. The locked steering helps prevent vehicle
theft.
Emergency off
If it is necessary in unusual circumstances, the
engine can be switched off while the vehicle is
moving. The engine will be switched off if you
press on the key for an extended period.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary . Be­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P. Oth­ erwise, the vehicle could inadvertently roll
away.
- The radiator fan can continue to run for up
to 10 minutes even after you have turned off the engine and removed the ignition key .
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.

Trailer mode
Weight distribution
Towing a loaded trai ler with an empty car res ults
in a high ly unstable distribution of weight. If this
cannot be avoided , drive at very low speeds only
to avoid the risk of losing steering contro l.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permiss ible speed. Reduce
your speed even more if load, weathe r or wind
conditions are unfavorable - particularly when
going downhill.
Reduce vehicle speed
immediately if the trailer
shows the s lightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
veh icles towing trailers are lower than for regular
ve hicles .
A lways app ly brakes ear ly. When driving down­
hill, shift into a lower gear to use the engine
brak ing effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coolant temperature
The coolant temperature gauge c::> page 10 must
be observed carefully.
If the need le moves close
to the upper end of the scale, reduce speed im­
mediately and/or turn off the a ir condit ioner.
If the coo lant temperature warning light in the
instr ument cluster starts flashing •• pu ll off
the road, stop and let the engine
idle for about
two minutes to prevent heat build-up.
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater r isk in an acc i-
206
-
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer mode notes
Important to know
Your vehicle handles differently when towing a
trai ler because of the additiona l weight and dif­
ferent we ight distribution . Safety, performance
and economy will greatly depend on how careful ­
l y you load your trailer and operate your rig.
Before you actua lly tow your trai ler, practice
turning, stopping and backing up in an area away
from traffic . Keep practicing until you have be ­
come comp lete ly familiar with the way your vehi­
cle-trailer comb inat ion behaves and responds.
Backing up is difficult and requires practice. Back­
ing up with a trai ler generally requires steering
action opposite to that when backing up your ve­
hicle without a tra iler.
Maintain a greater distance between your vehicle
and the one in front of you. Yo u will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turn ing radius.
When passing, remember that you cannot accel­
erate as fast as you norma lly wou ld because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your tra iler before changing lanes again.
Avoid jerky starts , sharp t urns or rapid lane
changes.
@ Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your Audi may requi re
more frequent maintenance due to the ex­
tra load
