Homelink®
Universal remote
control
General information
Applies to vehicles: with Horne Link® universal remote
control
The Homelink universal remote control can
be programmed with hand -held transmitters
from existing equipment.
Using the Homelink universal remote control,
you can operate equipment 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 doo rs and property gates. The
individua l 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. Using 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
Homelink ® 121
Homelink ® remote control is being pro­
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
certain that no persons or objects are lo­
cated in the range of motion of any
equ ipment being operated.

134 Safety belts
Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are nec­
essary, how they work and how to adjust and
wear them correctly .
.. Read all the information that follows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents . For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving .
- Pregnant women, injured, or physically
impaired persons must also use safety
belts. Like all vehicle occupants, they are
more likely to be seriously injured if they
do not wear safety belts. The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions: two in the front and three in the rear. In some
vehicles, there are four seating positions: two in the front and two in the rear. Each seating
position has a safety belt.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death.
- Never strap more than one person, in­
cluding small children, into any belt.
It is
especially dangerous to place a safety
belt over a child sitting on your lap. -
Never let more people ride in the vehicle
than there are safety belts available.
- Be sure everyone riding in the vehicle is
properly restrained with a separate safe­
ty belt or child restraint.
~ Safety belt warning light
Your vehicle has a warning system for the
driver and front seat passenger to remind you
about the importance of buckling-up.
Fig. 13S Safety bel t warning light in the instr ument
cl uster -enlarged
Before driving off, always:
.. Fasten your safety belt and make sure you
are wearing it properly.
.. Make sure that your passengers also buckle
up and properly wear their safety belts.
.. Protect children with a child restraint sys-
tem appropriate for the size and age .
The warning light . in the instrument cluster
lights up when the ignition is on as a reminder
to fasten the safety belts. In addition, you will
hear a warning tone for a certain period of
time .
Fasten your safety belt and make sure that
your passengers also properly put on their
safety belts.
A WARNING
-- Safety belts are the single most effective
means available to reduce the risk of se­
rious injury and death in automobile acci­
dents. For your protection and that of
your passengers, always correctly wear
safety belts when the vehicle is moving.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"" Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump­ tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en ­
g ine 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 con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"" Shut the engine off when you are not driv­
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions 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 .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over-
Dri vin g and en vironm ent 197
'
heating o r othe r damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"" Have your veh icle serviced at reg ular i nter-
vals.
By having your veh icle regu la rly serviced by an
Audi dealer he lps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its value, it a lso affects
fuel con sump­
tion .
Check your oil e ach t ime you fill your tank .
The amount of o il used is re lated to eng ine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven .
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss io n cont ro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alter or remove any device, such
as heat shie lds, swit ches, ign it ion w ires,
valves, which are designed to p rotec t
your vehicle's Emission Control System
and other important vehicle compo­
nents .
