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. This
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 138 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. This 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.
Homelink 135
- 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 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 hazard!
- 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.

200 Intelligent technology
There must be however sufficient ground ad ­
hesion . The hill descent assist can
not do its
job if the incl ine is icy or if the incline ground
is loose ¢,&..
The system does not work at speeds between
19 and 37 mph (30 and 60 km/h). The system
is then in the ready-mode. The diode in the
button will come on . The system automatical­
ly switched
off when you drive faster than 37
mph (60 km/h) . The diode will go out in this
case.
Active control at a specific speed up to approx­
imately 19 mph (30 km/h) w ill appear in the
instrument cluster display ¢
fig. 188. Two
dashes' '-- " w ill appear in the ready mode.
Hill descent assist is automatica lly act ivated
under the following cond itions:
- the diode in the button illuminates,
- vehicle speed is be low approximate ly
19 mph (30 km/h)
- the incline is 10%.
A WARNING
-Always adapt your speed to the weather,
road and traffic conditions . Do not let
the increased safety provided tempt you
into taking r isks.
- The hill descent assist system cannot
overcome the laws of physics. Your driv­
ing style must always be adapted to the
current road and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed un­
der all condit ions wh ile driving on an in­
cl ine (for example if ground under the
vehicle is loose).
Brake system
Operating conditions and driving habits
The brakes on today's automobiles are st ill
subject to wear, depending largely on operat­
ing conditions and dr iv ing habits ¢& . On
veh icles that are e ither driven mostly in stop­
and-go city traffic o r are driven hard, the
brake pads should be checked by your author- ized Audi dealer more often
than specified in
the
Warranty & Maintenance booklet. Failure
to have your 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 cont inuously. Pump the brakes at inter­
vals .
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing cond itions ice) on the brake pads. A
few careful brake applications should dry
off
the brake pads or remove any ice coatings .
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake discs in regular inter ­
vals so as to improve reaction time when brak­
ing on wet surfaces. You, the driver, will not
notice anything.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the b rakes are not used. Here too,
you should clean
off accumulated sa lt coating
from brake discs and pads with a few careful
applications of the brake ¢& .
Corrosion
The re may be a tendency for dirt to build up
o n the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with littl e use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion has formed on the discs, it is adv isable
to clean
off the pads and discs by braking
firmly a few times from a modera tely high
speed ¢£ .

208 Driving and environment
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
engine run at idle .
The idling phase is automatically reduced for
vehicles with the Start-Stop -System* . It is ef­
fic ient to sw itch
off the eng ine in vehicles
without the Start-Stop-System* when stopped
at railroad crossings and long red lights. Turn­
ing the eng ine
off for just 30-40 seconds
saves more fuel than is burned by sta rting the
engine again .
It takes a long time for the engine to wa rm up
fu lly when it is running at idle. However , wear
and nox ious 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.
(D Note
Do not leave engine idling unattended af­
ter starting. If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could resu lt in over­
heat ing or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumption. Check
your oil each time you fill your tank.
The amount of oi l used is re lated to engine
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 mi les
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fuel consumption and en­
gine output .
(0 Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Ma in­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion control system and could lead
t o damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shie lds , switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents.
' Fewer short trips
Fuel consumption will always be relatively
high on short trips.
... Try to avoid driving sho rt distances w it h a
cold engine .
T he eng ine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and nox ious emis­
sions effectively.
Jus t after starting, a cold engine in a mid-s ize
car only achieves a fuel economy of 6-8 mi les
per gallon (30 -40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg .,..

210 Driving o ff road
Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded for operation away
from paved roads. In situations where slip or a
d ifferential locking function is required, the
offroad mode can be activated
c::;, page 197.
Your Audi also has permanent all -wheel drive
in addit ion.
However, your Aud i is not a pure offroad vehi­
cle . It was not built for driving under extreme
conditions , e.g . for trips that are in the nature
of an expedition .
D riv e only on roads and off road sections
which match the design of your vehicle and
your abil ities a s a driver . Never take ri sks!
Before driving offro ad
- Check the engine oi l level, tire press ure,
coolant leve l, and the fluid level in the w ind­
shield washer reservo ir.
- Stow luggage items and other objects in the
l uggage compartment, and secure them
against slid ing around .
After driving offroad
- After trips offroad, remove any twigs and other foreign objects from the grill, the un­
derbody and the wheels. Pay specia l atten ­
t ion to fore ign ob jects (stones) which have
become lodged in the tire tread.
- Clean the body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty w indows, headlamp lenses, rear
li ghts, and license plates .
- Perform a brake check (part icu larly after
trave lling through water) .
A WARNING
- Drive especially attentively and plan
ahead in difficult road conditions and
w hen offroad . Excess ive speed or incor-
-
rect mane uvers can cause injuries and
damage to the vehicle.
- Always adapt your speed and driving
style to road, offroad, traff ic, and weath­
er cond itions. Drive especially slowly off­
road when your v iew is restricted.
- Please be aware that in offroad mode,
particularly on a smooth and slippery
road , the whee ls may have an increased
tendency to sp in and the vehicle may
b reak away- dange r of skiddi ng!
- Stability is limited in the offroad mode .
® For the sake of the environment
Avoid damage to the environment and re­
spect nature.

transmission, suspension or e lectr ica l
system can be severe ly damaged by driv­
i ng through water .
- Always switch off the Start-Stop-System*
when driving through water
c:> page 93.
@ Tips
-Check the depth of the water before driv­
i ng through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­

T ra ile r tow ing weight s
With a factor y-insta lled or an afte rm arket
trailer h itch, the max imum permissib le trailer
weight is 4,400 lbs (2,000 kg). The maximum perm iss ible unbraked trailer weight is 1,650
lbs (750 kg). These spec ifications apply when
driving on roads hav ing an incl ine of less than
12%.
P erm is s ible tongue load
For best vehicle handling under these
changed condit ions, adjust the trailer load so
that the tongue load is at the maximum al­
l owable or slightly lower . You can get an ap­
p rox imation of the tongue load w ith a bath­
room scale or you can measure the load at a
tr ucking company or weighing sta tion.
W ith a
fact ory -in stall ed or an aftermarket
trailer h itch, the max imum pe rm issible load
on the ball hitch may not exceed 440 lbs (200 kg).
It is recommended to use the maxi­
mum permissible load .
Trailer lo ad distribut ion
Be sure the load in the trai ler is held securely
in place to prevent it from shifting fo rward,
backward or s ideways.
N eve r allow a p assenger to rid e in a trail er
¢ .&. in Driving instructions on page 215.
Ball mount
The trailer hitch may only be used with su ita­
ble ball mount and ball¢
fig. 189. Installa­
tion of the hitch ball must be carr ied out in ac- cordance with the manufacturer's instruc­
tions.
Eng ine cooling system
T owing a t railer makes the engine work hard­
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid.
Tire pressur e
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressu re listed under
" F u ll load" on the tire pressure label. The tire
pressure label is located on the driver's side B·
pillar. Inflate trailer tires to trailer and tire
manufacturers' spec ificat ions.
Lights
T he headlight settings shou ld be checked wi th
the trai ler attached before driving off . Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the tra iler to the hitch on the ve­
hicle . Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they will not drag on the
road when you are driving.
T he chains should cross under the trailer
tongue to prevent it from dropping in case of separation from the hitch .
Driving instructions
Driving with a trailer always requires extra
core and consideration.
T o obtain the best possible handling of vehicle
and t railer, please note the fo llowing :
.,. Do not tow a loaded t railer when you r ca r it­
self is not loaded .
.. Be especially caref ul when passing ot her

A WARNING
-Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly flammable and can cause
severe bu rns and other injur ies.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fue l spray and overflowing fuel can
cause a fire .
- Never use a cellular telephone while re­
fue ling. The electromagnet ic rad iat ion
can cause spa rks that can ignite f uel va­
pors and cause a fire .
- Never get back into your vehicle whi le re­
fue ling.
If in exceptional circ umstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge
static e lectricity before touching the fill­
er nozzle again . Static e lectr icity can
cause sparks that can ignite fuel vapors
released du ring refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­ eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel conta iner in your vehicle . The con­
tainer, fu ll o r empty may leak and could
cause a fire, especially i n a c rash.
