park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
- The radiator fan can continue to run for
up to 10 minutes
even after you have

you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated. This can lead to seri­
ous injury.
- Never leave children or persons requiring
assistance unattended in the vehicle . The
doors can be locked using the remote
transmitter, preventing people from es­
caping from the vehicle on their own in
the event of an emergency. Depending

124 Homelin k
Homelink
Universal remote
control
Description
Appl ies to vehicles: wit h Homeli nk
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
W ith 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 replace
three d ifferent 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
div idual 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 programm ing of the sensor must
be performed before you are able to use sys­
tems with Home link. If the system does not
activate after performing the one-time pro­
gramm ing, check whether the system uses a
rolling code
q page 127 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 required 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. -
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, this can overstrain motor and
damage its e lectrica l components - an
overheated mo tor is a fire hazard!
- To avo id possib le injuries or property
damage, please always make abso lutely
certain that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

the engine is at its proper operating tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possib le.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .
allroad: Driving offroad
General information
Applies to vehicles: atlroad
When driving offroad, the funct ions for the
e lectronic stab ilization control (ESC) are ex­
panded. The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differentia l lock function is needed
c::> page 188. In addit ion, your Audi provides
continuous all wheel drive .
Your Audi is however , not an offroad vehicle.
Never drive the vehicle in terrain which is not
suitable for the vehicle, or which exceeds
your driving skills. Never take any unneces­
sary risks!
After driving offroad
-After driving offroad, remove branches and
other debris from the radiator grille, under ­
body, and wheels. Look especially for objects
(stones) that have been caught in the tire
tread .
- Clean the body and the vehicle underbody
and inspect the vehicle for possible damag­
es.
- Clean off the dirty windows, headlights, tail
lights and the license plate.
- Perform a brake test (especially after driving through water).
A WARNING
- Be espec ially aware and attentive when
dr iv ing under diff icult conditions . Dam­
ages to the vehicle and injuries may oc­
cur when driving at an excess ively high
speed or with incorrect driving maneu­
vers.
Driving and environment 199
- Always adjust your speed and handling
to the roads, terrain, traff ic and weather
conditions. Drive especially slow if off­ road with low visibility.
- Please note that the wheels can spin and
the vehicle can break away when the ESC
Offroad Mode is switched off, especially
when the road is slippery .
- Driving stability is reduced in the ESC
Offroad mode .
® For the sake of the environment
Avoid harming the environment and take
nature into cons ideration.
(D Tips
Only drive where it is allowed and always
stay on the provided roads and paths.
Driver messages
Applies to vehicles : a ll road
There is only one right way to drive in difficult
conditions: slowly and with caution!
When dr iving offroad, observe the following:
... Never drive the vehicle i n terrain which is
not suitab le for the vehicle, or which ex­
ceeds your driv ing ski lls. Never take any un­
necessary risks!
... Drive slow ly and cautiously!
... Pay attention to the
ground clearance of
your vehicle! This may vary depending on the load and composition of the ground and
the environment. The driver is therefore re­
sponsible for deciding whether a veh icle can
handle a specific situation.
... Act ivate the
ESC -Offroad-Mode c::> page 188
as needed.
Difficult terrain
Never dr ive in areas that are not familiar to
you and drive slowly when offroad and be pre­
pared and expect the unexpected (e.g. pot­
holes, boulders, tree stumps, etc.)
To prevent the vehicle from bottoming and avo id damage to the underbody, you should
drive straight across severe bumps in the
