Engine preheater
Applies to vehicles: with engine p reheate r
Use of the engine pre heater is recommended
when the ambient temperature is below
-5 °F
(-20 °C) .
Fig. 100 In t he l eft fron t bump er: en gine preheater
co nn ect ion socket
The engine preheater slowly w arms the en­
gine coolant using a heating element when
the vehicle is parked. The included cable
1>
must be connected to a 120 Volt Ground Fault
Circuit (GFI) protected outlet that is protected
from water (in your garage, for instance).
When the coolant is preheated, the engine
reaches its operating temperature more quick­
ly and will use less fuel and produce fewer
polluting emissions during the warm-up
phase.
Preheating the engine can take up to 3 hours
depending on the temperature outside.
Connecting the engine preheater
- Only use the cable provided.
-All cables and connectors that are used
must not be damaged
¢ .&.­
-Open the cover Q fig. 100 @.

an a uth orize d Au di d ea le r fo r veh icl es in the USA.
- Plug the connecting cable into the socket @
Q.ii_.
-Connect the connecting cable to the power
cord.
- Attach the extensions cord to the connector
cable. Always use a 12 gauge or heavier
heavy -duty extension cord that can be prop ­
erly grounded to a three-prong Ground Fault
Circuit (GFI) wall outlet and is not longer
than 100
ft (30 meters).
- Always plug the preheate r into an 120 Volt
Ground Fault Circuit (GFI) wall outlet that is
properly protected against rain and other
moisture. Never plug the preheater into a
normal outlet regardless of whether it is
grounded or not .
- Always disconnect the connecting cable and
close the cover
Q fig . 100 @ before starting
the engine.
_&. WARNING
-
Using incorrect or damaged outlet and
power cords, using electrical accessories
incorrectly or ignoring safety precautions
can lead to short circuits, accidents, inju­ ries and life-threatening electric shocks.
- Always plug the preheater into a
120 Volt Ground Fault Circuit (GFI) wall
outlet that is properly protected against
rain and other moisture.
- Always check the fuse protection of the
120 Volt power source before using the
connecting cable .
- Always use a 12 gauge or heavier heavy­
duty extension cord that can be properly
grounded to a three-prong GFI outlet .
The extension cord must not be longer
than 100
ft (30 meters).
- Always connect the cable to a 120 Volt
outlet that is grounded and protected
from water .
- Check the cable for damage before every
use . Never use a damaged cable.

Steering
Adjustable steering wheel
The height and reach of the steering wheel
can be adjusted .
Fig. 101 Lever under the steering column
First, adjust the driver's seat correctly.
• Push the lever
c:> fig . 101 down as far as it
will go
c:> & .
• Move the steer ing whee l to the desired po-
s it ion.
• Push the lever back up as far as it will go.
There must be at least 10 inches (25 cm) be­ tween your chest and the center of the steer­
i ng wheel. If you cannot si t more than 10 in­
ches (25 cm) from the steering whee l, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering whee l.
F or detai led information on how to adjust the
driver's seat, see
c:> page 63, Power seat ad­
justment.
The stee ring wheel can be adjusted even when
the ignition is turned off.
8_ WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
- Always make sure that the ad justment
lever is securely pushed up so that the
-
position of the steering wheel cannot be
changed unintentionally when the vehi­
cle is mov ing.
- Adj ust the driver's seat or steering whee l
so that there is a minimum of 10 inches
(25 cm) between your breastbone and
the steering wheel
c:> page 104,
fig. 117.
If you cannot maintain this
minim um distance, the airbag system
cannot protect you properly.
- If physical limitations prevent you from sitt ing 10 inches (25 cm) or more from
the steering wheel, check wit h your au­
thorized A udi dealer to see if adaptive
equipment is available .
- Pointing the steering wheel toward your
face decreases the ability of the s upple­
mental driver's airbag to protect you in
an accident. Always make sure that the
steer ing whee l is po inted towards your
chest.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock
positions to help reduce the risk of per­
sonal injury if the driver's a irbag inflates .
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steer ing wheel
rim or on the steering wheel hub. Ho ld­
ing the steering whee l the wrong way
can cause se rious inj uries to the hands,
arms and head if the driver's airbag in ­
f lates .

The engine can be started or turned off with
the ignition key.
Fig. 102 I gni tion lock positio ns
Ignition off@
In position ¢ fig. 102@both the ignition and
engine are off, and the steering is locked.
To
lock the steering after you have removed
the ignition key, turn the steering wheel in ei­
ther direction until you hear it lock into place.
You shou ld always lock the steering whenever

theft even more difficul t
q ,&.
Ignition on CD
If it is difficult to turn the key after you have
inserted it into the ignition lock, turn the
steering wheel back and forth. This will take
the load off the steering lock mechan ism and
you will be able to turn the key freely and
start the engine. On vehicles with a diesel en­
g ine*, the system can preheat in this pos ition .
Starting the engine @
In this position the engine starts. While the
engine is starting, the power supply to the
headlights and other electrical consumers is
temporarily interrupted to conserve battery power. After the engine has started, release
the key and it will return to position @.
Before the starter can be operated again the
key must be turned back to position @. The
non-repeat lock prevents you from damag ing
the starter when the engine is running.

A WARNING
-Never remove the key from the ignition
lock wh ile the vehicle is moving. The
steering wheel will lock caus ing loss of
control.
- If you have to leave your vehicle - even
for just a minute -always remove the ig­
nition key and take it with you. This is es­
pecia lly important if you are going to
leave children behind in the vehicle. The
children could start the engine or use
other vehicle controls. Unsupervised use
of vehicle controls (for example, power
windows) can cause serious personal in­
juries.
(D Tips
If the vehicle battery has been disconnect­
ed and then reconnected, then you must leave the key in position @for about 5
seconds before you can start the engine.

Glow plug system*
Diesel engines are e quipped w ith a glow pl ug
system whose prehe ating time is co ntrolled
by the coo la nt an d ou tside temperature . Sta rt
the engine
immediately after the g low plug

T he glow plug indica to r ligh t will only illumi­
nate fo r approximate ly 1 second w hen t he en ­
gine is warm or the outside temperature is
higher than
46 °F (8 °(). That means yo u can
start the eng ine
immedia tely .
To start the diesel eng ine after the fuel
tank has been run dry
If the fuel tank was r un comp lete ly dry, the
starting process after refue ling with diesel
fuel can take longer than usua l - up to one mi­
nute . This is because the fue l system first has
to be vented of a ir wh ile s tarting .

@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Mainta in moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine
.. Turn the ignition key to position@
¢page 89, fig. 102.
_& WARNING
-Never turn off the engine unti l the vehi­
cle has come to a complete stop.
- The brake booster and servotronic on ly
work when the engine is running . With
the ignition turned off, you have to apply
more force when steering or braking.
Since you cannot steer and stop normal­ ly, this can lead to accidents and serious
injuries.
- The rad iator fan can continue to run for
up to 10 minutes even after you have
tu rned off the eng ine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.
(D Note
Do not stop the engine immediate ly after
hard or extended dr iving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up .
