-Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
mJ illu­
minates and a driver message appears
¢ page 9 7 when the clutch is overload­
ed .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
¢ page 214. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
0 Note
-S tronic- and tiptronic transmission:
When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling.
- S tronic- and tiptronic transmission: Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv ­
er's safety belt is engaged in the buckle.

Hill descent control
App lies to vehicles : wi th mult itronic/ S tro nic/tiptro nic
The hill descent control system assists the
driver when driving down declines .
Hill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de­ scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may still be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
¢ page 89 , hill descent control is also activat­
ed when the speed is set.
.&_ WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes .

106 Audi adap tive cruise control and br aking guard
- If a co llision is imminent, the system will
first provide an
acute warning by bri efly and
sharp ly app ly ing the brakes .
- If you do not react to the ac ute warning ,
braking guard can brake within the limits of
the system. This reduces the veh icle speed
in the event of a collision.
- At speeds under 20 mph (30 km/h), the sys ­
tem can in it iate a complete deceleration
s hortly before a collision
l) .
-If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force.
Which funct ion s can be contr oll ed ?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MM I c> poge 106, Settings in the radio/
MMI.
A WARNING
Lack of attention can cause col lisions, oth­
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collis ion by itself. The
driver m ust always intervene . T he d river is
always responsib le for bra king at the cor­
rect time.
- Always pay close attention to traffic,
even when the brak ing guard is switched
on. Be ready to intervene and be ready to
take complete control whenever necessa­
ry. A lways keep the safe and legal dis­
tance between your vehicle and vehicles
up ahead.
- Braking guard works w ith in limits and
will not respond outs ide the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
l ) Th is is not available in some c oun tri es.
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving veh icles up ahead may not
be prompt ly detected or may not be de­
tected at all .
- Reflective surfaces including crash barri­
ers or tunne l entrances may impair the
function of the radar sensor .
(D Tips
- You can cancel the braking that is in it iat­
ed by the system by braking yourse lf, by
accelerating not iceably or by swerving .
- Braking guard error messages

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.

Safety is everybody's responsibility!
Important things to do before driving
Safety is everybody's job! Vehicle and occu­
pant safety always depends on the informed and careful driver.
For your safety and the safety of your passen­
gers,
before driving always:
.,. Make sure that all lights and signals are op­
erating correctly.
.,. Make sure that the tire pressure is correct .
.,. Make sure that all windows are clean and af­
ford good visibility to the outside.
.,. Secure all luggage and other items carefully
qpage 64 .
.,. Make sure that nothing can interfere with
the pedals.
.,. Adjust front seat, head restraint and mirrors
correctly for your height.
.,. Instruct rear seat passengers to adjust the
head restraints according to their height.
.,. Make sure to use the right child restraint
correctly to protect children¢
page 167,
Child Safety. "'

-Passengers must always sit in an upright
position and never lean against or place
any part of their body too close to the
area where the airbags are located.
- Passengers who are unbelted, out of po­
sition or too close to the airbag can be
seriously injured by an airbag as it un ­
folds with great force in the blink of an
eye .
- Always make sure that there are at least
10 inches (25 cm) between the front
passenger's breastbone and the instru­
ment panel.
- Each passenger must always sit on a seat
of their own and properly fasten and
wear the safety belt belonging to that seat.
- Before driving, always adjust the front
passenger seat and head restraint prop­
erly.
- Always keep your feet on the floor in
front of the seat. Never rest them on the
seat, instrument panel, out of the win­
dow, etc. The airbag system and safety
belt will not be able to protect you prop­
erly and can even increase the risk of in­
jury in a crash .
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in­
jury due to incorrect positioning of the
safety belt and improper seating posi­
tion.
- Children must always ride in child safety
seats <=:>
page 167 . Special precautions
apply when installing a child safety seat
on the front passenger seat <=:>
page 146.
Proper seating positions for passengers
in rear seats
Rear seat passengers must sit upright with
both feet on the floor consistent with their
physical size and be properly restrained
whenever the vehicle is in use.
To reduce the risk of injury caused by an incor­
rect seating position in the event of a sudden
braking maneuver or an accident, your pas-
Driving Safely 131
sengers on the rear bench seat must always
observe the following:
.,. Make sure that the seatback is securely
latched in the upright position <=:>
page 69.
.,. If there is a passenger on the rear center
seating position, slide the center head re­
straint upward at least to the next notch.
.,. Keep both feet flat in the footwell in front of
the rear seat .
.,. Fasten and wear safety belts properly

& WARNING ~
Passengers who are improperly seated on
the rear seat can be seriously injured in a
crash.
- Each passenger must always sit on a seat
of their own and properly fasten and
wear the safety belt belonging to that seat.
- Safety belts only offer maximum protec­
tion when the seatback is securely latch­
ed in the upright position and the safety
belts are properly positioned on the
body. By not sitting upright, a rear seat
passenger increases the risk of personal
injury from improperly positioned safety
belts!
- Always adjust the head restraint properly
so that it can give maximum protection . •

r isk of serious personal injury and death
whenever a veh icle is being used .
- Always make sure that all vehicle occu­
pants stay in a proper seating pos ition
and are properly restra ined whenever the
vehicle is be ing used.
Pedal area
Pedals
The pedals must always be free to move and
mus t never be interfered with by a floor mat
or any other object.
M ake sure that all pedals move freely without
i nte rferen ce and that no thing prevents them
from re tu rning to the ir origin al posi tions.
Only use floor mats that leave the pedal area
free and can be secured w ith floor mat fasten­
e rs.
If a brake circuit fails, increased brake peda l
travel is required to br ing the vehicle to a full
stop.
8_ WARNING
Pedals that canno t move freely ca n cause
loss o f vehicle control a nd incr ease the r is k
o f serious injury.
- Never pl ace any ob jects in the d river's
f ootwell. An object could ge t into the
peda l area and inter fere with pedal func­
tion . In case of s udden braking or an ac­
c ident, you would not be able to brake or
accele rate!
Dr iving S afel y 133

Stowing luggage
Loading the luggage compartment
All luggage and other objects must be prop­
erly stowed and secur ed in the luggage com­
partment.
Fig. 141 S afe load positio nin g: place heavy objects as
l ow a nd a s far forward as pos sible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle hand ling
characteristics. Loose items can also increase
the risk of serious personal injury in a sudden
vehicle maneuver or in a collision .
.,. Distribute the load even ly in the luggage
compartment .
.,. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as possible¢
fig. 141.
.,. Secure the load with the cargo net* or with
non -elastic straps secured to the tie-downs*
¢ page 71 ¢page 72 .
.,. Make sure that the rea r seatback is secu rely
latched in place.
.&_ WARNING
Improperly stored luggage or other items
can fly throug h the vehicle ca using serious
personal inj ury in the event of hard brak­
ing or an accident. To help reduce the r isk
of serious personal injury: -
Always put objects, for example, luggage
or other heavy items in the luggage com ­
partment.
- Always secure objects in the luggage
compartment using the t ie-down eyelets
and suitable straps.
.&_ WARNING
-
Heavy loads w ill influence the way your ve­
hicle handles . To help reduce the risk of a
loss of control leading to serious personal
in jury:
- Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
veh icle handling :
- Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible .
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
veh icle to slide and handle differently.
- Please observe information on safe dr iv­
ing
c> page 128.
.&_ WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always
keep the rear lid closed while driving.
- Never transport objects larger than
those fitting completely into the luggage
a rea because the rear lid cannot be fully
closed.
- If you absolutely m ust dr ive with the rear
lid open, observe the following notes to
red uce the risk of poisoning:
- Close all windows,
- Close the sunroof,
- Open all air outlets in the instrument
panel,
- Switc h off the ai r recirculation,
- Set the fresh air fan to the highest
speed.

A WARNING
Always make sure that the doors, all win­dows, the sunroof and the rear lid are se ­
curely closed and locked to reduce the risk
of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open .
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
c:>poge234.
Driving Safely 135
Tie-downs
App lies to veh icles : w ith tie -d owns
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo prop­
erly
c:> page 134, Loading the luggage com ­
partment .
In a collision, the laws of physics mean that
even smaller i tems that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a
10-lb (4.5 kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be
about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment could cause in a collision like this.
A WARNING
----Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous missiles into the pas­
senger compartment .
- Never attach a child safety seat tether
strap to a tie-down . •
