Homelink
Universal remote
control
General information
Applies to vehicles: with Home link unive rsal remote con­
tro l
The Homelink universal remote control can
be programmed with hand -held transmitters
from existing equipment
Using the Homelink universal remote control,
you can operate equ ipment such as garage
doors, property gates and house lights from inside your vehicle .
Using the Homelink universal remote control,
you can replace up to three separate hand ­
held transmitters for equipment on your
property with just one universal remote con­
trol. Most of these transmitters a re used to
operate ga rage doors and property gates. The
individual transmitters are programmed at
the front bumper. That is where the control
module is located.
The transmitters must be programmed first in
order to operate systems using the Homelink
universal remote control.
A WARNING , .,.
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federal safety stand­
ards . Th is includes any garage door open ­
er model 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 . Us ing a garage door
opener without these features increases
risk of serious injury or death.
- For safety reasons never release 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

grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its electrical components -an
overheated motor is a fire hazard!
- To avoid possible injuries or property
damage, please always make absolutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being ope rated.

Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applicat ions .
-If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed . Otherwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
cr eased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dea ler or q ualified wor kshop .
- Never let the vehicle rol l to a stop w ith
t he engine shu t off.
- If the brake booster is not work ing, the
brake pedal must be pressed conside ra­
bly harder to make up for the lac k of
booster assistance.
Brake booster
The brake booster adds extra braking power.
The brake booster works w ith vacuum pres ­
sure which is created only when the engine is
ru nning

,&. WARNING
-Never le t the vehicle ro ll to a stop w ith
t he engine shu t off.
- If the brake booster is not work ing, fo r
ex ample when towing your ve hicl e, or
because the b rake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
Servotronic - advanced
power steering system
-
The power steering systems use the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys­
tem senses the road speed and electron ically
ad ju sts powe r ass istance to provide comfor ta-
Int ellig ent technolog y 203
ble and safe steering response exactly match ­
ed to th e vehicle speed .
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be h ard
to tu rn.
T he powe r stee ring fluid level is checked d ur­
i ng t he sched uled maintena nce services.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will s till fu nction like a conven­
tiona l powe r steering system, providing a
constant steering s upport force tha t is no
l onge r proportionate to the vehicle speed.
This is most noticeab le when t urni ng the
steering wheel at low speeds (for example
when parking), -more effort w ill be re­
quired than usual.
- Be aware of the different than usual steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right by an Audi dealer as soon as possible.
(D Tips
-When the engine is running, never hold
the steering wheel turned all the way to
the right or to the left for longer than 15
seconds . The power steering pump will
overheat the hydraulic fluid if yo u keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering sys tem.
- If the powe r stee ring system should fa il
entire ly, o r if t he engine is not runn ing
(for example, wh ile be ing towed), you
w ill still be able to steer the veh icle .
However,
considerably more effort will
be required to do so .
- If the powe r steering system sho uld
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately.
- The power steering system req uires a
specially formu lated hydraulic fluid. The
power steering fluid reservoir is located
in the engine compartment
