If not hing is hung on the hooks, they wi ll fold
back in by themselves .
I n a coll is ion, the laws of phys ics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can ca use
serio us injury . Items in the vehicle p ick up ki­
netic energy which varies w ith the vehicle and
the we ight of the item . Veh icle speed is the
most significant factor .
F or example, in a frontal collisio n at a speed
of 30 mph (48 km/h), the forces acting on a 10- lb (5 kg) object a re about
20 times the
normal weight of the item . Th is means that
the we ight of the item would suddenly be the
equ ivalent of about 200 lbs (90 kg). O ne can
eas ily imagine the injuries that an item of that
weight flying free ly through the passenger
compartmen t can ca us e in a co llision a t a
speed considered relat ively low .
8_ WARNING
Weak, damage d or improper straps used
to secure items to tie -downs can fail du r­
ing hard b rak ing or in a col lision and cause
serious personal in jury.
- Always use suitab le retaining straps and
properly secure items to the tie-downs in
t h e luggage compartment to help pre ­
vent items from shifting or flying for­
wa rd .
- Never attac h a child seat tether strap to
a tie -down.
- For st rength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb . (5 kg) . Heav i­

-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.
Transmission 95
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
c>poge 107.
- Keep in mind that braking guard can brake unexpectedly. Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury .

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.
