A WARNING
-The ski sack is intended only for the
transportation of skis and other light ob­
jects. To reduce the risk of serious per­
sonal i njury, never transport heavy or
pointed objects in the ski sack. -
When braking rapid ly or during an acci­
dent, the load could be displaced and
cause injury to occupants.
- Sharp edges on the load must be covered
for protection. A lways fasten the belt
tightly around the sack and its contents
¢fig. 88.
-For safety reasons, do not transport
more tha n two pairs of skis in t he ski
sack.
- You must secure the ski sack with the
strap after load ing.
- Make sure all objects that you are trans­
port ing in the pass-through are secured.
Othe rwise they could slide around du ring
sudden b rak ing ma ne uvers and cause in­
Jury.
(D Tips
- Never stow the ski sack away when it is
st ill wet o r damp (for example, snow
me lting from skis). Allow it to dry com­
pletely be fore stow ing it away.
- When transporting sk is or snowboa rds,
tighten the securing st rap between the
bindings .
- Pos ition skis in the sk i sack with the
pointed ends facing the front and ski
poles with the pointed ends facing the
re ar.
- Sedan: Y ou can lo ck or unloc k the pass­
t hrough using the mechan ica l key. This
prevents any access to the l uggage com­
partment from the vehicle interior .

-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
[O] 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 213, Engine compartment . Oth­
erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied .
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 veh icles: w it h m ult itro nic/S tro nic/t iptro 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 .
1>.
- 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 must always intervene . The driver 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

130 Driving Saf ely
- Passengers must always sit in an upright
posit ion 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
sit ion or too close to the airbag can be
seriously injured by an airbag as it un ­
folds with g reat force in the blink of an
eye.
-Always make sure that there are at least 10 inches (25 cm) between the front
passenge r's breastbone and the inst ru­
ment pane l.
- Each passenger must always s it on a seat
of the ir own and properly fasten and
wea r the safety belt be long ing to that
seat.
- Before driv ing, a lways adjust the front
passenge r seat and head restra int prop­
er ly .
- Always keep your feet on the f loor in
front of the seat . Never rest them on the
seat, instrument pane l, out of the win ­
dow, etc . The airbag system and safety
belt w ill not be ab le to protect you prop­
erly and can even increase the risk of in­
jury in a crash .
- Never drive with the backrest recl ined or
t ilted far back! The farther the backrests
are t ilted back , the greater the risk of in­
jury due to incorrect positioning of the
safety belt and improper seating posi­
t ion.
- Children must always ride in child safety
seats ¢
page 166 . Special precautions
apply when installing a child safety seat
on the front passenge r seat ¢
page 145.
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 s udden
braking maneuver or an accident, your pas- sengers on the rear bench seat must always
observe the following:
.. Make s ure that the seatback is secure ly
la tched in the up right pos ition ¢
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 be lts properly
¢ page 140 .
.. Make sure that children are always properly
restrained in a child rest raint that is appro­
priate fo r the ir s ize and age¢
page 166.
& 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 sec urely latch­
ed in the upright position and the safety belts are properly posit ioned on the
body . By not sitting upright, a rear seat
passenger increases the risk of personal
injury from improperly positioned safety
be lts!

Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat
or any other object.
M ake sure that all pedals move freely without
in te rfe ren ce and that nothing prevents them
from retu rni ng to the ir origina l posi tions.
Only use floo r mats that leave the pedal area
free and can be secured with f loor mat fasten­
e rs.
If a brake circuit fails, increased brake pedal
travel is required to br ing the vehicle to a full
stop.
A WARNING
Pedals t hat canno t move freely ca n cause
loss o f vehicle control and in cr ease the r is k
o f serious injury.
- N ever pl ace any o bje cts in t he d river 's
f ootwell. An objec t could ge t into the
peda l area and inter fere w ith pe dal func ­

All Luggage and other objects must be prop­ erly stowed and secured in the luggage com­
partment.
F ig. 1 41 Safe lo ad pos itio nin g: pl ace heavy objects as
l ow a nd a s far forwa rd a s possible .
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 evenly in the luggage
compartment .
.,. Always place and properly secure heavy
items in the luggage compartment as low
and as far forward as poss ible
c> fig. 141 .
.,. Secure the load w ith the cargo net* or with
non -elastic straps secured to the tie -downs*
c> page 71 c>page 72 .
.,. Make sure that the rear seatback is secu rely
latched in place.
A WARNING
Improperly stored l uggage or other items
can fly through the vehicle caus ing serious
personal inj ury in the event of hard b rak­
ing or an accident. To help reduce the r isk
of serious personal injury :
Drivin g Sa fely 133
-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 suitab le straps.
A WARNING
Heavy loads wi ll influence the way your ve­
h icle handles . To help reduce the risk of a
loss of control leading to serious personal
i n 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 hand ling:
- 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 We ight Rating
specif ied 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 different ly .
- Please observe informat ion on safe dr iv­
ing
c> page 127 .
A WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, a lways
keep the rear lid closed w hile driving.
- Never transpo rt objects larger than
those f itting comp lete ly into the luggage
area beca use the rear lid cannot be f ully
closed.
- If you absolutely m ust dr ive with the rea r
lid open, observe the following notes to
red uce the r isk of poisoning:
- Close all windows,
- Close the sunroof,
- Open all air outlets i n the instrument
panel,
- Swi tc h off the air rec irculat ion,
- Set the fresh air fan to the highest
speed.

134 Driving Safely
A WARNING
Always make sure that the doors, all win­
dows, 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:>page238.
-
Tie-downs
Applies to vehicles: with tie -downs
The luggage comportment is equipped with
four tie-downs to secure luggage and other
items .
Use the tie-downs to secure your cargo p rop­
erly
c:> page 133, Loading the luggage com ­
portment .
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 .
