outlet, regardless of whether it is protected
against a short circuit or not.
- Always disconnect the connector cable and
close the cover
(D before starting the engine.
.&_ WARNING
Using the engine preheater incorrectly can
cause short circuits, electric shocks, fire, seri­
ous injuries and death.
- The connector cable must always be con­
nected to a grounded 120 Volt socket that
is equipped with a GFI circuit breaker . Al­
ways protect the sockets from water, mois ­
ture and other fluids .
- Never plug the engine preheater into a con­
ventional outlet, regardless of whether it is protected against a short circuit or not .
.&_ WARNING
-
Short circuiting, fire, serious injuries and life­
threatening or lethal electric shock can result
from using unsuitable or damaged sockets and connector cables/extension cords, using
electrical equipment incorrectly, and/or disre­
garding general safety precautions.
- Always plug the extension cord into a 120 V
socket that is properly functioning, ground­
ed, equipped with a GFI circuit breaker and
is protected against water, moisture and
other fluids.
- Never connect the engine preheater to a
conventional socket, even if the socket is
protected by a fuse.
- Always check the fuse on the 120 Volt GFI
socket before connecting the connector ca­
ble to the engine preheater on the vehicle.
- Only use highly durable extension cords that
are class 12 or better and can be properly grounded to a three-prong wall socket with
a GFI circuit breaker . The extension cord
must not be longer than 100 feet (30 me­
ters).
- Never use damaged connector cables, ex­
tension cords or sockets . Always check the
connector cable, extension cord and sockets
for damage before using them. Damaged
parts must be replaced. If damaged, replace
76
the engine preheater connector cable at an
authorized Audi dealer or authorized Audi
service facility .
- Only use the connector cable provided to
connect the vehicle socket to a suitable
power source. Use a suitable extension cord
if necessary .
- Always disconnect the connector cable from
the vehicle socket before starting the en­
gine. Switch off the power supply to the
connector cable and to the extension cord if necessary, or disconnect the cable or exten­
sion cord from the 120 Volt socket equip­
ped with a GFI circuit breaker. Never leave
the connector cable or extension cord con­
nected to a live power source.
- Never make alterations or repairs to the
connector cables or extension cords that
supply power to the engine preheater or to
any components that affect the engine pre­
heater.
- Always protect the connections from water,
moisture and other fluids. Always store the
connector cable and extension cord securely
and in a dry place when they are not being
used, and disconnect them from the power
source before storing .
(D Tips
Test the GFI circuit breaker once a month if
you use the engine preheater occasionally, and test it weekly if you use it regularly.

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 . ..,.

You must drive your vehicle about 3,000 miles
(5 ,000 kilomet ers) before you can prop erly as ­
sess o il consumption .
This a lso applies to fuel consump tion and engine
output .
(D Note
-Have your vehicle mainta ined properly and
i n accor dance wi th the service re commenda­
tions in yo ur War ranty
& Maintenance book ­
l et. Lack of proper maintenance as well as
i mproper 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 Em ission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shie lds, sw itches, ignition wires,
valves, which a re designed to protect yo ur
vehicle's Em ission 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
engi ne .
T he eng ine and catalytic converter have to reach
their optimal
operating tempe rature 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 miles per
ga llon (30-40 l/100 km). A fter about a half a
m ile , fuel economy cl imbs to 12 mpg (20 l/
100 km) . After about
2.5 miles (4 km), the en­
g ine is a t its prope r operating temperature and
fuel economy has reache d a normal level. So you
c a n see t hat you s hou ld avoid sho rt t rips whenev­
er possib le .
The
outside temperature is also cr itical in th is re­
g ar d. Yo ur car c onsumes mo re fuel in the w in ter
than in the s umme r.

Driving
_& 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.
- 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 brak.ing 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.
- 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 the result of heat buildup 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
engine. For this reason, let the engine run for
at idle for approximately two minutes before
shutting it off.
