The steering wheel position is fully adjustable
up and down and forward and bock .
Fig. 87 Lever under the steering column
F irst, adjust the driver's seat correctly .
• Pull the lever
r:> fig . 87 <=> &_ .
• Move the steer ing whee l to the desired posi­
t ion.
• Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween you r chest and the center of the steer­
i ng wheel. If you cannot sit 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 wheel.
F or detai led information on how to adjust the
driver's seat, see
r:> page 61 .
A WARNING
Improper use of steeri ng wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering whee l co lumn on ly
when the veh icle is not moving to pre­
vent loss of veh icle control.
- Adjust the driver's seat or steering wheel
so that there is a minimum of 10 inches
(25 cm) between your chest and the
steering wheel
c;, page 122, fig . 132. If
yo u cannot mainta in this min imum dis- tance, the airbag system cannot protect
you proper ly.
- If physical limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive
equ ipment is ava ilable .
- If the steer ing wheel is aligned with your
face, the supplementa l driver's a irbag
cannot provide as much protection in an
accident . Always make sure that the
steer ing wheel is aligned with your
chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never hold the stee ring wheel at the 12
o'clock position or with your hands inside
the steeri ng wheel rim or on the steering
wheel hub . Holding the steering wheel
the wrong way can cause se rious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

• Insert the key into the ignition lock .
• Step on the brake pedal and move the selec-
tor lever to the P or N pos ition. ..,..

88 Transmission
order to adjust the gears to the driving condi­
tions by hand
¢page 89.
On slopes, activate the parking brake first and
then move the selector lever to the P position.
This prevents too much stress from being placed on the locking mechanism.
Vehicles with multitronic transmission : Your
vehicle is equipped with
hill hold assist allow­
ing you to start while on an incline. The sys­
tem is activated when the brake pedal is pressed down and held
for a few seconds. The
br ake pre ssure will hold for
a moment after
the brake pedal loosens to preven t the vehicle
from rolling backwards while starting up.
A WARNING
- The vehicle can also roll when the engine
is stopped .
- Unintended vehicle movement can cause serious injury .
- Never leave your vehicle with the engine
running while in gear . If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill . Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system. -
To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake .
- Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload . An indicator lamp
mJ illu­
minates and a driver message appears
¢ page 91 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
¢ page 206. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­
plied .
(D Note
-S tronic- and tiptronic transmission :
When stopping on an incline, do not try
to hold the vehicle in place by pressing the accelerator pedal while a driving gear
is selected . This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake pedal to prevent the vehicle from rolling .
- S tronic- and tiptronic transmission : Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from dev ices
in your home with one universal remote. Th is
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code¢
page 120 for vehicles without
the
MMI*.
& WARNING
-
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federa l safety stand­
ards. Th is includes any garage door open­
er mode l manufactured before April 1,
1982.
-A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 11 7
-For safety reasons never re lease the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire haza rd!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
brake pads do not possess their fu ll braking
effect, they have to be "broken in" first
c> .&. .
You can compensate for this slightly reduced
braking power by push ing harder on the brake pedal. Avoid heavy brak
ing loads dur ing the
break -in period.
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving hab its
c> .&. . On
vehicles that are either driven mostly in stop­ and-go city traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have you r brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine . This way, you prevent un ­
necessary wear on the brake system.
If you
must use your brakes, do not hold the brakes
down continuous ly . Pump the brakes at inter­
vals.
Operating noise
Noises may occur when braking depending on
the speed, b rak ing force and outside cond i­
t ions such as temperature and humidity .
Effect of water and road salt
In certain situations, for example after driv in g
t hr ough water, in heavy rain, after overnight
condensation or after washing you r car, the
braking effec t can be reduced by mois ture or
ice on the brake rotors and brake pads. The
brakes must be dried first with a few careful
brake applications .

188 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it .
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water .
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic conv ert er) is function ­
ing properly to ensure that your vehicle is run­
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 201,
Fuel supply .
,,. Never run the tank down a ll th e way to emp ­
ty.
,,. Never put too much moto r oil in your engine
Q page 211 , ~ Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean­
up" device built in to the exhaust system of
the vehicle . The catalytic converter burns
many of the polluta nts in the exhaust gas be ­
fore they are released into the atmosphe re . The exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert­
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop­
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
CI) Note
- Be aware tha t just o ne tank filling with
leaded fu el w ill alre ady ser io usly de ­
grade the performance of the cata lytic
converter .
- Do not exceed the cor rect engine oil level
Q poge 211.
-Do not drive until the fuel t ank becomes
comple tely empty . The engine cou ld mis ­
fire . Unburned fuel could also get into
the exhaust system and th is co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
co uld result in overheating of the con­
verter, requir ing its replacement.
