Manual climate control system*
For a comfortable temperature, we recommend :
- in warmer times of the year, set the tempera-
ture so that it is only a few degrees below the
outside temperature .
- set the blower at a moderate speed
- don't direct the air flow directly on the passen- gers
IA/C l Switching the cooling mode* on and off
The cooling mode only functions with the blower
turned on . The air is not cooled and humidity is
not removed when cooling mode is switched off.
This can cause fog on the windows. The cooling
mode switches off automatically when there are
cold outside temperatures.
~ Adjusting the blower
To prevent the windows from fogging over, the b lower should a lways run at a low speed. When
the w indows are fogged, we recommend using a

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.
78
· 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 . ..,.

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 with both hands on the
rim or the center of the steer ing whee l.
Holding the steering wheel inco rrectly s ig­
nificantly incr eas es the risk of inju ry to the
h ands, arms and head if t he ai rbag dep loys.

tion look while the vehicle is moving . Other­
wise the steering lock will engage and you
will 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 usual steering and braking capa­
bility is not available, the risk of accidents or
injuries increases.
- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise the
children could start the engine or operate
electrical equipment such as power win­
dows .
- Avoid high engine speed, full throttle, and
heavy engine load as long as the engine has
not reached operating temperature yet . You
could damage th@ engine.
-The engine cannot be started by pushing or
towing .
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions.
(D Tips
- If it is difficult to turn the key to position
(D, turn the steering wheel back and forth
slightly to release the steering wheel lock .
- Some noise after starting the engine is nor­
mal and is no cause for concern.
- If the battery is disconnected and recon­
nected, you have to hold the ignition key in
position
(D for five seconds for the engine
to start.
- After switching the ignition off, you can only
remove the key when the selector lever is in
the "P" (Park) position. After that, the selec­
tor lever is locked.

A WARNING
.--
- Never turn off the engine before the vehicle

ous injuries.
- Never remove the ignition key from the igni­

gage and you would not be able to steer the
vehicle.
