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 .

Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&..
Low brak e flu id level
Malfunct ions can occur in the brake syste m if
the brake fl uid leve l is too low. The b rake fluid
l eve l is monito red electronically.
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op­
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*)~ .&,.
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in­
spection
~ page 2 73, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too long or too often. This could cause the
brakes to get hot and dimin ish b raking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the b rakes to
overheat, premat ure wear and increased
stopp ing distance .
- Under certain climat ic and operating
c ondit ions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
Int ellig ent technolog y 201
for a test . Brakes will dry and ice coat­
ings w ill be cleaned
off after a few care­
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few ca reful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the ai r
f low to the front brakes is not obst ruct­
ed. Otherw ise the bra ke system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one b rake circuit will impair
the braking capab ility result ing in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est a uthorized Audi dea ler or q ualified
workshop.
- Never let the vehicle roll to a stop with
the eng ine shut off .
- If the b rake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.

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 .,..

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, please remember
that the additional load will affect durability,
economy and performance .
T railer towing not only places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always follow the operating
and driving instructions provided and use
common sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and must be
mounted securely on the vehicle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
¢ &. .
Trailer brakes
If your trailer is equipped with a braking sys­
tem, check to be sure that it conforms to all
regulations .
Trailer towing 213
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
Trailer lights must meet all regulations . Be
sure to check with your authorized Audi dealer
for correct wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear vision to the rear .
.8, WARNING
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
hicle. The vehicle was not designed for
these kinds of trailer hitches . The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle .
- The Gross Vehicle Weight Rating for your
vehicle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any circumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not
be covered by your Limited New Vehicle
Warranty. Exceeding the Gross Vehicle
Weight Rating will also change the per­
formance and handling characteristics of
your vehicle, which could cause a crash resulting in serious injury or death.

Fig. 189 Pe rmi tted ball posit ion of the tra iler h itch
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
vehicles.
.. Observe speed limits.

218 Vehicle care and cleaning
A WARNING
- Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents .
- To reduce the r isk of cuts, protect your­
self from sharp meta l components w hen
wash ing the unde rbody or the inside of
the whee l housings.
- After washing the vehicle, the braking ef­
fect may be de layed due to mo isture on
the b rake ro to rs or i ce in the winter. The
brakes must be dried first with a few
careful brake applications.
(!;) Note
- If you wash t he vehi cle in an automatic
ca r wash, yo u m ust fold the exterior m ir­
ro rs in to reduce the r is k of damage to
the mirrors. Power folding exte rior m ir ­
ro rs * must only be folded in and out us­
i ng the power folding function.
- Compare the track of your vehicle wit h
the distance between the gui de rails of
the facility - there is a risk of damage to
the wheels and t ires.
- Compare the height and width of your
vehicle with the he ight and width of the
tunnel at the fac ility. -
To p revent paint damage, do not wash
the vehicle in di rect sunlight.
- T o reduce the ris k of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- M atte finish painted veh icle compo ­
nents:
- To reduce the risk of damage to the
surface, do not use polishi ng agents or
hard wax.
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers o r magnet ic
signs on v ehicle parts painted w ith
ma tte fi nish paint. The paint cou ld be
damaged when the stickers o r mag nets
a re removed .
@ For the sake of the environment

VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hang ing th e engin e oil
The engine oil and oi l filter must be changed
according to the m ileage (kilomete rs) and
time inte rva ls specified in yo ur vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive eng ine repairs.
Changing the o il at the recommended inter ­
va ls is so very important because the lubricat ­
ing properties of oi l decrease gradually during
norma l vehicle use . If you are not sure when
you have your oi l changed, ask your author­
ized Audi Service Advisor.
Under some circ umstances the engine oi l
should even be changed more frequently .
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and -go traffic con ­
d itions, or when you use your veh icle where
temperatures stay below freezing point for l ong periods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing for a short time. This is norma l and is not
a reason to change the o il mo re often than
r ecommended.
Damage or ma lf u nction s du e to lac k of
ma intenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW S07 00 (veh icles with diese l engi ne). Yo ur
L im ited New Vehicle Warra nty does not cover
damage or ma lfunctions due to failure to fol­
l ow recommended maintenance and use re­
quirements as set forth in the A udi Owner's
Manual and Warranty
& Maintenance book let.
Your dealer will have to deny warranty cover­ age un less you present to the dea ler proof in
the form of Service or Repa ir Orders that a ll
Checking and fillin g 235
scheduled maintenance was performed in a
timely manner.
· Engine oil consumption
The engine in your vehicle depends on an ade ­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to prov ide effective lubrication and
cooling o f inte rna l engine components, all in ­
ternal combustion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine to engine and may change sign ificantly
over the life of the engine. Typically, engines
with a spec ified break-in period (see
Q page 205) consume more oil during the
break-in pe riod than they consume after o il
consump tion has stabilized.
Under normal cond itions, the rate of oi l con­
sumption depends on the quality and viscos ity
of the oil, the RP M (revolut ions per minute) at
which the engine is operated, the ambient
tempe rature a nd road conditions. Furt her fac­
tors are the amount of oil dilut ion from wa ter
condensation or fue l residue and the oxida ­
tion level of the oi l. As any engine is subject to
wear as mi leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es­
tablished or spec ified. There is no alternative
to regular and frequent check ing of the o il lev­
el, see
Not e.
If the yellow engine oil level warning symbo l
in the instrument cluster
II lights up, you
shou ld check the oil leve l as soon as possib le

General information
Unde r normal operating conditions, the bat ­
tery in your A udi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the elect ro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec­
trolyte leve l sho uld a lso be c hecked each t ime
