2000 AUDI ALLROAD air condition

---------------------CONTROLS AND
EQUIPMENT
General notes
• Vehicle heating is depend upon tne tem­
perature of the engine coolant -therefore,
your vehicle interior will warm uponly when
the engine has reached its operating tem­
perature.
When the ambient temperature is too low,
the fan only switches to high speed modes
when the coolant has reached a sufficiently
high temperature, or when the ® button
has been depressed.
• Keeping the air intake slots in front of the
windshield free from ice, snow and debris
helps to make sure that the climate control
system will work properly.
• When the air conditioner compressor is
on it reduces both the temperature and the
humid ity of the air inside the vehicle. This
prevents the windows from fogging up.
• The air conditioner works best with the
windows and power roof* closed. •
If the inside temperature is very high af­
ter the vehicle has been parked in the sun,
open windows and allow the hot air to es­
cape before switching on the air condi­
tioner.
• The dust and pollen filter will prevent
dust and pollen etc. in the outside air from
entering the car. Switch to air recirculation
to prevent unpleasant fumes from entering
the vehicle.
If water drips under the
vehicle ...
At high outside temperatures and humidity,
condensation may drip from the evaporator.
This is normal and does not indicate a leak.
If the airflow is not cool ...
• At low ambient temperatures the air con­
ditioner compressor switches off automati­
cally. The compressor cannot be switc hed
on again in this case, even by pressing the
AUTO button. •
The air conditioner may switch itself off
temporarily to ensure sufficient engine
cooling when the engine is running at full
load.
The air conditioner will also be switched off
temporarily in the kick-down function. See
page 109.
• Check the air conditioning fuse on the
fuse p imel -see page 27 4. Have it replaced,
if necessary.
• If you suspect that the air conditioner is
damaged, for instance after an accident,
switch to the ECON and have the system
examined immediately for leaks or other
damage.

CONTROLS AND
EQUIPMENT--------------------
Maintenance
• For maximum efficiency of the air condi­
tioner the dust and pollen filter elements
must 'be replaced at the intervals indicated
in the Maintenance Schedule.
• The condenser must be checked regu­
larly to make sure it is clean. If it becomes
obstructed by dirt or insects, spray 1t clear
with water.
• Repairs to the Audi air condition­
ing system require specialized
knowledge and special tools.
If the system is not functioning
properly, contact your Audi Dealer.
16 8 Power roof*
The roof will slide open or tilt up at the rear
as required. When the ignition is on it can be
opened and closed by turning the rota�
control next to the interior light. The roof 1s
tilted open or closed by pressing or pulling
the control -see illustration.
When turning the ignition off, however, the
sunr oof can still be operated as long as the
driver's and front passenger's door are
closed. When either door is opened, sliding
roof operation will be deactivated .
Always close the roof completely if you are
going to park your vehicle and leave. �W
ARNING
Be careful when closing the power
roof 1 tilt roof. Not paying atten­
tion could cause you or others to
be caught and injured as the roof
closes. To help avoid injuries
caused by closing the roof, always
take your key whenever you leave
your vehicle.

CONT
ROLS AND
EQUIPMENT---------------------
.·
Emergency closing
If you cannot close the roof with the electric
switch, you can still close the roof manually
using a crank (see right illustr ation). The
crank is located behind the fuse cover (see
page 274).
In order to access the power roof motor, re­
move the interior light (lens and housing) as
follows:
• Place the flat side of the screwdriver
found in the vehicle tool kit on the rear side
of the lens as shown in the illustration and
carefu lly pry the lens downward.
17 0 •
Then insert the screwdriver into the gap
between the light housing and the frame in
the rear on the side and carefully pry out the
housing.
To close the roof, press the manual
crank (1) into the hex socket (2) until it en­
gages. Keep pressing down and turn the
crank.
Reinst all the light housing and lens in the
reverse order.
Have the problem corrected by your autho­
rized Audi dealer. Power
roof with solar panel*
The solar panel is operated in the same way
as the power roof. The roof's solar cells sup­
ply energy for the air conditioner blower.
See page 166.
The interior trim is fixed to the solar panel
cannot be opened and closed separately.

VEHICLE OPERA
TION-----------------------
Operate your vehicle safely
The condition of the vehicle is es­
sential for driving safety.
Therefore, always be sure to observe the
following points before you drive off:
• Check lights and turn signals.
• Check fuel level.
• Adjust the mirrors.
• Make sure that all lights and all
windows are clean.
• Make sure the air Intake slot be­
tween the engine hood and the
windshield is free of leaves, snow
and ice.
• Check warning and indicator
lights when starting the engine.
For driving safety, always follow the speci­
fied maintenance intervals in your Mainte­
nance booklet -especially for changing
the brake fluid, see page 242.
Yo ur personal driving style and your
attitude affect driving safety to a
very great extent.
19 4 Therefore,
for your own safety:
• Wear your safety belts and wear
them properly, even if you're just
driving in the city or to the corner
store -see page 14.
• Make sure that all passengers are
wearing their safety belts properly,
even those sitting in the rear -
see page 14.
Passengers not wearing safety belts endan­
ger not only themselves in case of an acci­
dent, but also the driver and other passen­
gers.
• Make sure that children always sit
on the rear seat properly restrained
by a res traint system appropriate
for their size and age.
• Never transport a child in a rear­
facing child or infant seat on the
front passenger seat.
• Adjust your seat so that you can
easily reach all controls as far away
from the airbag as possible but no
closer than 10 in. (25 em) -
see page 76. •
The seating position is very im­
portant for the airbag performance
- see page 29.
• Always adjust the head restra ints
to the correct height.
For maximum protection, the upper edge of
the head restraints should be at least at
eye level, or higher .
• Always make sure that the move­
ment of the pedals is not restricted
In any way-see page 102.
• Store luggage and light items
properly
in the luggage compartment ­
see page 88.
of the roof - see page 191.
• If you drink, do not drive.
The use of alcohol, drugs and certain medi­
cations will seriously impair perception,
reactions and driving ability, and substan­
tially increase the risk of an accident and
personal injury.

VE
HICLE OPERATION------------------------
The external conditions
in which you drive also affect your fuel con­
sumption.
The following conditions increase fuel con­
sumption:
• Heavy traffic, especially in large cities
with many traffic lights.
• Stop-and-go driving, especially short dis­
tances so that the engine never warms up
as it should.
• Driving in heavy, slow moving traffic in
low gear so that the engine speed is rela­
tively high when compared to the distance
driven.
� Plan your trips ahaad of time. Or­
� ganizs your trips to include sev­
sral errands and to avoid heavy traf­
fi c.
Of course, there are some conditions that
will affect fuel consumption that you can't
control.
For example, fuel consumption increases in
the winter or under difficult conditions (bad
roads, towing a trailer, etc.).
19 6 The
technical requirements
for optimum fuel consumption and eco­
nomy were ''built" intoyourvehicle. Special
attention was paid to the environment. To
reta in and make use of these characteris­
tics, please note the following points:
riJ Use only unleaded gasoline.
Leaded gasoline causes damage to the cat­
alytic converter and other components of
the emission system.
t:Gh Have your vehicle serviced by an
� Audi Dealar at the specified in­
tervals -see page 228 and your
Main tenance booklet.
Having your vehicle regularly serviced by an
Audi Dealer helps ensure that it runs prop­
erly and economical ly, that it does not dis­
turb the environment, and that it has a long
service life. t:Gh
Check
your tire pressure once a
W month.
Low tire pressure increases fuel consump­
tion and tire wear, and impair s vehicle han­
dling.
�W ARNING
Underinflation and overloading of
tires can lead to tire failure. Sud­
den failur e on the road could cause
a serious or fata l accident. See
page 253 for inflation informa­
tion.
� Do not carry unnecessary items
in the luggage compartment.
Particularly in city traffic where you must
often accelerate, weight influences fuel
consumption.

----------------------VEHICLE
OPERATION
,:lib Remove
supplementary roof
� rack components when not In
use.
At high road speeds, the increased air �e­
sistance caused by the cross bars also In­
creases fuel consumption.
,:lib Switch oH any electrical equip­
� ment when no longer needed.
The more electricity you consume, the
higher the fuel consumption.
,:lib Check your vehicle 's fuel co?­'l!�Sr sumption regularly. Keep a writ­
ten record or use the trip odometer .
Check your fuel consumption ea?h time you
refu el. By doing this, you can d1scov �r a �y
inc onsistencies which could result 1n In­
creased fuel consumption and have these
checked before other problems appear. •
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
engine to reach its lowest value after a cer­
tain mileage has been driven.
You must drive your vehicle about 3,000
miles (5 000 kilome tres) before you can
properly assess oil consumption.
This also applies to fuel consumption and
engine output.
• The published ENVIRONME NTAL
PROTECTION AGENCY (EPA) and
Tr ansport Canada consumption esti­
mates may not correspond to your
actual consumption on the road.
which will vary depending upon ve­
hicle load and speed. road and
weather conditions. trip length. etc. The
catalytic converter is an efficient
"clean-up" device built into the exhaust
system of the vehicle. The catalyttc convert­
er burns many of the pollutants in the ex­
haust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is
critically important fo.r the life of
the catalytic converter and proper
functioning of the engine - see
page 225.
The catalytic converter will be per­
manently damaged by:
• Exc eeding the correct engine oil
level - see page 236;
• Driving until the fuel tank be­
comes completely empty. The en­
gine could misfire. Unburned fuel
could also get into the exhaust sys­
tem and this could cause the catalyt­
ic converter to overheat;
197

VE
HICL E OPER ATION ------------------------
• Tu rning off the ignition while the
vehicle is movin g-sea page 115 -or
• Other unusual operating condi­
tions.
Do not continue to operate your ve­
hicle under these conditions, as
otherwise fuel can reach the catalyt­
ic converter. This could result in
overheating of the converter, requir­
ing its replacement.
To assure eHiciant operation of the
Emission Control System:
• Have your vehicle maintained
properly and in accordance with the
service recommendations in your
Maintenance booklet.
Lack of proper maintenance as well
as improper usa of the vehicle will
impair the function of the emission
control system and could lead to
damage.
19 8 Cl
Do not alter or remove any com­
ponent of the Emission Control Sys­
ta.m unless approved by the
manufacturer.
• Do not alter or remove any device,
such as heat shields, switches, igni­
tion wires, valves, which are de­
signed to protect your vehicle 's
Emission Control System and other
important vehicle components.
Nota
Do not leave engine idling unat­
tended after starting. If warning
lights should come on to indicate
improper operation, they would go
unheeded. Extended idling also pro­
duces heat, which could result in
overheat ing or other damage to the
vehicle or other property. �W
ARNING
• Parking
Do not park or operate the vehicle
in areas where the hot exhaust sys­
tem may coma in contact with dry
grass, brush, fuel spill or other ma­
terial which can causa a fire.
• Undercoating
Do not apply additional undercoat­
ing or rustproofing on or near the
exhaust manifold, exhaust pipes,
cata lytic converter or heat shields.
During driving, the substance
used for undercoating could over­
heat and causa a fire.

-----------------------VEHICLE OPERATION
Driving on rough roads or rugged terrain
For off road use, your Audi allroad is
equipped with a 4-level air suspension ride­
height adjustment system, in addition to all
wheel drive.
Yo ur vehicle's ground clearance (ride height)
can be adjusted to changing terrain condi­
tions with the push of a butt on.
At the highe st level setting (maximum clear­
ing level), ground clearance is 8.2 inches
(20.8 em).
Some general tips
Navar drive on terra in that is too de­
manding for the design of your ve­
hicle or for your driving abilities.
Navar t�;�ke any unnecessary
chances!
• Before you take your vehicle off-roa d,
make certain that you know how to operate
the ride height adjustment system-see pa­
ge 153. •
Make sure that you adjust the ride height
just before you travel on any rough sections
of terra in.
• Always adjust the vehicle's speed
to the trail and terrain conditions.
• Stow any luggage or other items in the
luggage compartment and make certain
that they are properly secured so that they
do not shift.
• Never travel on any roads, trails or terrain
on which motor vehicle travel is prohibited.
r.:Cib Always protect the environ­W ment. Respect our natural su�
roundings.
• After traveling off-road, remember to re­
move any branches or other foreign objects
caught in the grille, underbody or wheels. In
particular, look for foreign objects (stones)
caught in the tire treads.
Check the vehicle for possible damage.
• Clean dirty windows, headlight and tail­
light lenses and license plates. •
Check your brakes after traveling off-road
especially after driving through water.
• If need be, clean the underbody, suspen­
sion parts, etc. (for example, in an under­
body wash).
Some driving tips
Unpaved roads and off-road
• Drive slowly on unfamiliar roads and ter­
rain, and stay alert for unexpected hazards
(for example, potholes, rocks and stumps).
• To avoid hanging up the vehicle and dam­
aging the undercarriage on extremely un­
even terrain, drive over large humps with
the hump in the center of the vehicle.
Instead, always drive over the hump with
the vehicle wheels on one side of the ve­
hicle positioned over the crown of the
hump.
