Warm and cold Climate control system
Description
The climate control system* cools and removes
humidity from the air in the vehicle interior. It is
the most effect ive when the windows and power
top are closed. If there is a build-up of heat in­
side the vehicle, ventilation can help to speed up
the cooling process. Because of this, the windows
can be opened from outside.
¢ page 34, Conven­
ience opening/closing
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key recognition
Different climate control system* settings are
stored and assigned to the remote control key
that is be ing used .
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar as quickly as possible with
the correct use and function of the climate
control system, especially with the defrost­
ing and defogging function.
- When the temperature is below freezing,
only use the windshield washer system after
the windshield has been warmed by the cli­
mate control system. The washer fluid could
Warm and cold
freeze on the windshield and impair visibili­
ty.
@ Note
- If you suspect that the climate contro l sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an authorized Audi dealer
or authorized Audi Service Fac ility.
@) For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshield must be free of ice, snow or leaves.
- Condensation from the cooling system* can dr ip and form a pudd le of water under the
vehicle. This is normal and does not mean
there is a leak.
- 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 supply has been
restored.
- The flows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug­
gage compartment cover.

Driving
General information
The first 1,000 miles (1,500 km) and afterwards
The new engine needs to be run-in during the
first 1,000 miles (1,500 km) .
For the first 600 miles (1,000 kilom eter s):
.,. Do not use full throttle.
.,. Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
.,. Avo id high engine speeds .
From 600 to 1,000 mile s (1 ,000 to
1 ,500 kilomete rs ):
.,. Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed .
During and aft er bre ak-in pe riod
.,. Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in
N (Neutral) or in gear .
After th e br eak-in p eriod
.,. Do not exceed maximum engine speed under
any circumstances .
.,. Upshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
opage 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
mov ing parts have been broken in. How well this
break-in process is done depends to a considera­
b le extent on the way the veh icle is driven during
the first 1,000 miles (1,500 kilometers).
CD Note
Extremely high eng ine speeds are automati­
cally reduced. However, these rpm lim its are
programmed for an engine well run-in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds - upshifting early saves fuel, reduces
noise and protects the environment.
D riv ing
Driving through water on roads
Note the following to avo id vehicle damage when
driv ing th rough water, for examp le on flooded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body .
- Do not dr ive faster than walk ing speed .
.&, WARNING ..__
After driv ing through water or mud, the brak­
i ng effect can be reduced d ue to moistu re on
the brake d iscs and bra ke pads. A few careful
brake applications should dry off the brakes.
CD Note
Vehicle components such as the engine,
transmission, suspension o r electrical system
can be severely damaged by d riving throug h
water.
(D Tips
- Determine the depth before dr iving through
water.
- Do not stop the vehicle, d rive in reverse or
switch t he engine off when d riving through
water .
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
ma ke it too deep for yo ur vehicle to drive
through safe ly.
- Avoid dr iv ing th rough salt wate r (cor rosion) .
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, env ironmental impact, and wear
on your engine, brakes and t ires largely depend
on three factors:
- your personal driving style
- operat ing cond itions
- technical limitations
65

Driving
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­ ronment and your pocketbook.
(D Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi ­
ble -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
.. Try and keep well below your car's maximum
speed .
Accelerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­ ment.
Fuel consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half . Never drive faster than the posted
speed limit and weather conditions permit.
66
· Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the engine off when you are not driving
the vehicle .
.,. Do not warm up the vehicle by letting the en-
gine run at idle .
It is efficient to switch off the engine when stop­
ped at railroad crossings and long red lights.
Turning the engine off for just 30 -40 seconds
saves more fuel than is burned by starting the
engine again .
It takes a long time for the engine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially high when
the engine is warming up . So you should drive
away as soon as you start the engine and avoid running at high rpms while the engine is still
warming up .
@ Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs properly
and economically. The condition of your vehicle
not only affects its safety and ability to hold its
value, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile -
age has been driven . ..,.

<( co ..... N
" N ..... 0
" > 00
You must drive your vehicle about 3,000 miles
(5 ,000 kilomet ers) before you can prop erly as­
sess oil consumption .
This also applies to fuel consumption and engine output.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage .
- Do not alter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
• Try to avoid driving short dist ances with a cold
engine .
T he eng ine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consump tion and noxious emissions effec­
tively .
Just after starting, a cold engine in a mid-si ze car
only achieves a fuel economy of 6-8 mi/gal (30-40 l/100 km) . After about a half a mile , fuel
economy climbs to 12 mpg (20 l/100 km) . After
about
2.5 miles (4 km), the engine is at its prop­
er operating temperature and fuel economy has reached a normal level. So you can see that you
should avoid sho rt trips whenever possible.
The
outside temperature is also critical in this re­
gard . Your car consumes more fuel in the winter
than in the summer .
Driving
Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.
Fig. 74 St ee ring co lumn: steering col umn adjus tmen t leve r
• Tilt the lever¢ fig. 74 downward ¢&_ .
• Bring the steering wheel into the desired posi­
tion.
• Push the lever against the steering column un­
til it latches.
A WARNING
-
Incorrect use of the steering wheel adjust­ ment and an incorrect seating position can
cause serious injuries .
- Only adjust the steering column when the
vehicle is stationary so that you do not lose control of the vehicle.
-
- Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches (25 cm) dis­
tance between your chest and the steering
wheel
r:!> page 125, fig. 120. If you do not
maintain this distance, the airbag system
will not be able to provide its full protection
r:!> page 125, fig. 120.
-If your physical characteristics prevent you
from sitting at least 10 inches (25 cm) or
more away from the steering wheel, see if
your authorized Audi dealer or authorized
Audi Service Facility can provide adapters
that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision . Always make sure
that the steering wheel is level with your
chest.

Driving
-Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi ­
t ions to reduce the risk of injury if the airbag
deploys.
- Never hold the steer ing whee l in the 12
o'clock posit ion or w ith both hands on the

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
steer ing is not guaranteed. You must use
more force to turn or brake. Because you
cannot stee r and brake as you usually
wou ld, this could lead to acc idents and seri­
ous injuries.
- Never remove the ignition key from the igni­
tion lock while the vehicle is moving. Other­
wise, the steering lock could suddenly en­
gage and you wou ld not be able to steer the
vehicle.
- Please note that the brake booster and pow­
er steering only work when the engine is
running . When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usua l steering and braking capa­
b ili ty is not available, the risk of acc idents or
injuries increases.
- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of t ime . This applies part icularly when chil ­
dren remain in the vehicle . Otherwise the
children could start the engine or operate
electrical equipment such as power win­
dows.
- For safety reasons, always park the vehicle
w ith the selector lever in the P position.
Othe rw ise, there is the risk that the vehicle
could rol l.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off . It can also switch on again after some
time if the coolant temperature rises as the
result of heat bu ildup or if the engine com­
partment is heated by the sun's rays and the
engine is hot.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off -there is a risk of damaging the
