a) Tips
The instrument illumination for the needles
and dials turns on when the ignition is turned
on and the lights are turned off. The illumina­
t ion fo r the dials reduces automatically and
eventua lly turns off as brightness outside in­
creases . This function reminds the driver to
turn the headlights on at the appropriate
time.
Engine coolant temperature gauge
The engine coo lant gauge (D Q page 10, fig. 3
only works when the ign ition is on. To prevent
10
damage to your engine, please note the follow­
ing important points:
Engine cold
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, heavy en­
gine loads and heavy throttle applications.
Normal temperature
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on when the engine is
under heavy load or the exterior temperature is
high . Th is is no need to worry as long as the.
warning light in the instrument cluster does not
ill uminate .
If the LEDs in the upper area of the
display and the indicator light. in the instru­
ment cluster display turn on, the coolant temper­
atu re is too high
Qpage 15.
A WARNING
-Always observe the warning in <9page 216,
before opening the hood and checking the
engine coolant level.

-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment. You
could burn yourself. Let the engine cool off
first until you can no longer see or hear steam or coolant escap ing .
Q) Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or h igh engine load, the engine cou ld
ove rheat.
- 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 red uce the cooling effect and the en­
gine could then overheat . Ask your author ­
ized Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You shou ld shift to the next lowest gear when
the speed is below 1500 RPM. The beginning of
the red zone in the tachometer indicates the maximum permissib le engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before reaching the red zone, you should shift into the
next h igher gear, choose the Dor S selector lever
position, or remove your foot from the accelera ­
tor pedal.
CD Note
The tachometer needle© c::> page 10, fig. 3
should only be in the red zone br iefly: other­
w ise, this increases the risk of e ngine dam-
age. The location where the red zo ne begins
varies depend ing on the eng ine.
@, For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.

-If the 1111 (USA models) . (Canada mod­
els) brake system indicator light turns on to­
gether with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
have failed. Functions that stabilize the ve­
hicle are no longer available . This could
cause the vehicle to swe rve and increase the
risk of sliding. Drive carefully to the nearest
authorized Audi dealer or other qualified
workshop and have the ma lfunction correct ­
ed.
- If the brake warn ing/ indicator light does
not go out after a few seconds and the park­
ing brake is re leased, or lights up while you
are driving, the flu id level in the brake fluid
reservoir is too low. If you believe that it is
safe to do so, proceed immediately at low
speed to the nearest authorized Audi dealer
or qualified repair facility and have the brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond w ith
maximum stopping power in critical situa­
tions . You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.
PARK /(® ) Electromechanical parking brake
The warning/indicator light monitors the elec ­
tromechanical parking brake.
If the indicator light- (USA models)/ .
(Canada models) turns on, the parking brake was
set .

Warm and cold Climate control system
Description
App lies to vehicles: with three-zone climate control or four ­
zone a utomat ic climate contro l
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 sun­
roof* are closed .
If the temperature inside the
parked vehicle becomes very warm, opening the
window briefly will speed up the cooling process.
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.
Condensat ion 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.
T he 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
Three-zone climate control: The blower setting
and air distribution are stored automatically and
assigned to the remote contro l key that is in use.
Four-zone automatic climate control: Th e cli­
mate control settings are automatically stored
and assigned to the remote contro l key that is in
use.
Warm and cold
A 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 .
- 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 vent ilation system. The washer so lu­
tion may freeze on the w indshield and re­
duce visibility.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repa irs to the Aud i air cond itioner require
special technical knowledge and special
tools. Contact an authorized Audi dea ler for
assistance.
@ For the sake of the environment
By reduc ing 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 availab le
again as soon as the energy balance has
been restored .
- Air escapes through vents under the rear
window. When placing items of clothing on the luggage compartment cover, ensure
that the openings are not covered.

At both of these settings, the climate control sys ­
tem runs continuously at maximum cooling or heating power. T here is no temperature regula­
tion .
Adjusting the blower~
You can adjust the volume of air generated by the
b lower to your preference. To have the blower
r e gulated automatica lly, press the
IAUTO I but­
ton .
~ Adjusting air distribution
You can manually select the vents where the air
will flow. To have the air distribution regu lated
automatically , p ress the
IAU TO ! button.
~ Adjusting seat heating*/seat ventilation*
Pressing the button switches the seat heating/
seat ventilat ion on at the highest setting (leve l
3). The LEDs indicate the temperature level. To
r educe the temperature, press the button again .
To switch the seat heating/seat venti lation off,
press the button repeatedly until the LED turns
off.
Afte r 10 minutes, the seat heating automatically
switches from level 3 to level 2.
l The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off . The temperature shou ld be
set to approximate ly 22
° C.
The IAU TOI button sw itches the defroster off.
IQ:il REAR I Switching the rear window defogger
on/off
The rear window heate r o nl y operates when the
engine is running. It sw itches off automatically
after a few minutes, depending on the outs ide
temperature.
To prevent the rear w indow heater from switch­
ing off automatically, press and hold the
lljjjl REAR I
button for more than 2 seconds. This remains
stored until the ignition is switched off.
Warm and cold
I SYNC ! Synchronization
When synchronization is switched on, the set­
tings for the driver's s ide are applied to the front
passenger's side (except for seat heating/ventila­
tion *). The s ettings in the rear are also synchron ­
i z ed. Synchronization switches off if the settings
are adjusted on the front passenger's side or in
the rear.
You can synchronize the settings in a row by
pressing and holding a control. For example, to
apply the settings for the front passenge r's side
to the driver's side, press and hold the control on
the front passenger's s ide . The same applies to
the rear.
Residual heat*
With the ign ition turned off, you can activate the
residual heat function by pressing the~ button
<=> fig. 75. The residual heat from the coolant is
used to heat the veh icle inter ior . The residual
heat function sw itches off automat ica lly after
about 30 minutes.
Air vents
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con ­
sole and door pillars using the ridged thumb­
whee ls. Th e levers adjust the direction of the air­
flow from the vents.
_&. WARNING
-You should not use the recirculation mode
for an extended period since no fresh air is
drawn in. With the air-conditioning switch­
ed off, the windows can fog up, which in­
creases the risk of an accident.
- Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heat ing funct ion. To reduce
the risk of injury, these individuals should
not use seat heating .
(D Note
To avoid damage to the heating elements in
the seats, do not kneel on the seats or place
heavy loads on a small area of the seat.
71

Driving
-After the engine has been sw itched off, the
rad iator fan can continue to run for up to 10
minutes - even with the ign ition switched
off . It ca n also switch on again after some
t ime if the coolant temperature rises as the
r esult of a heat buildup o r if the eng ine is
hot and the eng ine compartme nt is addi­
ti onal ly he ated by the su n's rays.
@ Note
Do not stop the engine immed iate ly after
hard o r ex tended d riving. Keep the engine
running for app rox im ately two m inutes to
prevent exces sive hea t build-up.

A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not p roperly wearing the restraints p rovided
by Audi.
Trailer mode notes
Important to know -
Your vehicle handles differently when towing a
trailer because of the additional weight and dif­
ferent weight distribution. Safety, performance
and
economy will greatly depend on how careful­
ly you load your trailer and operate your rig .
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traff ic. Keep practicing until you have be­
come comp letely fami liar with the way your vehi­
cle-trailer comb inat ion behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trailer generally requires steer-
Trailer mode
ing action opposite to that when backing up your
vehicle without a trailer .
Maintain a greater distance between your vehicle
and the one in front of you. You will need more
room to stop . To compensate for the trailer, you
will need a larger than normal turning radius .
When passing, remember that you cannot accel­
erate as fast as you normally wo uld because of
the added load . Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your veh icle.
-If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load ¢
page 2 73.
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
"Apply the foot brake .
" Have someone place chocks under both the ve­
hicle and the trailer wheels.
"W ith chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
" Turn the whee ls towards the curb.
" App ly the parking brake.
" Select the P selector lever position.
When restarting after parking:
"App ly the foot brake.
" Start the engine .
"S elect the D/S se lector lever position.
" Release the parking brake and slowly pull out
and away from the wheel chocks.
" Stop and have someone retrieve the wheel
chocks.
