If you anticipate w hat you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. Th is sect ion will
g ive you some tips on how you can help the envi­
ronment and your pocketbook.
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depend ing upon vehicle load and
speed, road and weather conditions, trip
length, e tc.
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 b le -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 be low your car's max imum
speed .
Accelerating gently reduces fuel consumpt ion,
engine wear, and does not d isturb the env iron­
ment .
Fue l consumption, exha ust emissions and eng ine
noise increase disproportionately at high speeds.
If you drive at approx imately t hree quarters of
top speed, fuel consumpt ion w ill be reduced by
one half . Never dr ive faste r than the posted
speed limit a nd weather conditions perm it.
Dri ving
Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the eng ine off when you are not driving
the vehicle .
.. Do not warm up the vehicle by lett ing the en-
gine run at idle.
It is efficient to switch off the engine when stop­
ped at ra ilroad crossings and long red lights.
Turning the engine off for just 30-40 seconds
saves more fuel than is b urned by starti ng the
engine aga in .
It takes a long t ime for the engine to warm up
fully when it is ru nning at idle. However, wear
and noxious emissions are espec ia lly hig h when
t h e engine is warming up. So you should d rive
away as soon as you sta rt the eng ine and avoid
run ning at high rpms w hile the eng ine is s till
warmi ng up .
@ Note
Do no t leave eng ine idl ing una ttended afte r
s ta rtin g.
If war ning lig hts s hou ld come on to
i ndica te imprope r operat ion, they would go
u nheede d. Extended idling also produces
heat, which could result in overheat ing or oth­
er damage to the ve hicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your ve hicle serviced at reg ular in tervals.
B y havi ng your ve hicle regu la rly se rv iced by an
Audi dealer he lps to ensu re that it ru ns p rope rly
and economically. The condi tion of your veh icle
not only affects its sa fety and ability to ho ld i ts
val ue, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certai n m ile-
age has been dr iven. ...,

-Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi ­
tions to reduce the risk of injury if the airbag
deploys .
- Never hold the steer ing wheel in the 12
o'clock position or w ith both hands on the
rim or the center of the steering wheel.
Holding the stee ring wheel incorrectly sig­
nificantly increases the risk of injury to the
hands, arms and head if the airbag deploys.

Driving
& WARNING
-Never allow the engine to run in confined
spaces, because this increases the risk of as ­
phyxiation.
- Never
remove the ignition key from the igni­
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 .
CT'.) Note
- Avoid high engine speed, full throttle, and
heavy engine load as long as the engine has
not reached operating temperature yet . You
could damage the 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.
- After starting a cold engine, there may be a
brief period of increased noise because the
oil pressure must first build up in the hy­
draulic
valve adjusters . This is normal and
not a cause for concern.
- If the battery is disconnected and recon­
nected, you have to hold the ignition key in
74
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.
Stopping the engine with the key
App lies to vehicles : with mechanical ignition loc k
Stopping the engine

steering wheel lock.
The locked steering helps prevent vehicle theft.
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. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri ­
ous injuries.
- Never
remove the ignition key from the igni­
tion look while the vehicle is moving . Other­
wise, the steering lock could suddenly en­
gage and you would 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.

children 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
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- 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 a
result of heat build up or if the engine com­
partment is heated by sunlight and the en­
gine 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 engine . For this reason, let the engine
run for at idle for approximately two mi­
nutes before shutting it off.
