Tie-downs and cargo net
The cargo net* prevents small objects from
sliding .

.. Read and heed all WARNINGS ¢ page 132,
Stowing luggage.
In a collis 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 cause
serious injury. Items in the veh icle pick up ki­
netic energy which varies with the vehicle and
the weight of the item. Vehicle speed is the
most significant factor.
F or example, in a frontal coll is ion at a speed
of 30 mph (48 km/h), the forces acting on a
10- lb (5 kg) object are about
20 times the
normal weight of th e item. This means that
the weight of the item would suddenly be the
equivalent of about 200 lbs (90 kg). One can
easi ly imagine the injuries that an item of that
weight flying freely through the passenger
Seats and storage 65
compartment can cause in a collision at a
speed considered relatively low.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-down s can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable retaining straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward.
- Never attach a child seat tether strap to
a t ie-down .
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weigh ing up to 10 lb. (5 kg). Heavi­
er objects will not be adequately secured
- there is a risk of injury.

A WARNING
-The ski sack is intended only for the
t ransportation of skis and other light ob­
jects . To reduce the risk of serious per­
sonal inj ury never t ransport heavy o r
pointed objects in the ski sack .
- When brak ing rapidly 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 . Always fasten the belt
tightly around the sack and its contents
¢ fig. 70.
(D Tips
- Never stow the ski sack away when it is
still wet or damp (for example, snow
melting from skis). Allow it to dry com­
pletely before stowing it away.
- Position skis in the ski sack with the
pointed ends facing the front and ski
poles with the pointed ends facing the

fluctuations, changes to the load condi ­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
ly tie the vehicle down at the running
surface of the tires, which is the outer
circumference. Secur ing the vehicle at
the axle components, suspension struts
or tow ing eyes is not permitted because
the pressure in the air suspension struts
can change d uring transpor t. The vehicle
may not be sec ured s uff icient ly if this
happens.
- If you are going to tow a trailer, you
must activate the trailer ope rat ion mode

WARNING
Pay attention to traffic when operating
Audi drive select to prevent potential risk
of an accident.

110 Automatic Tran sm iss ion
multitronic transmission : Your vehicle is
equipped with
hill hold assist allowing you to
start while on an incline. The system is acti­
vated when the brake pedal is pressed down
and held
f o r a few s econds . The brake pres­
sure will hold for
a moment after the brake
pedal loosens to prevent the veh icle from roll­
ing backwards whi le starting up .
A WARNING
- The veh icle can also roll when the engine
is stopped.
- Unintended veh icle movement can cause
serious injury .
- Never leave your vehicle with the eng ine
running wh ile in gea r. If you must leave
yo ur vehicle when the engine is running,
act ivate the park ing brake and move the
selector lever to P .
- Power is st ill transmitted to the whee ls
when the engine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever pos ition
wh ile the vehicle is stat io nary and the
engine is running .
- Never shift into R or P wh ile driving .
- Before driv ing down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when dr iving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces b raking performance, inc reases
braking distance or causes comp lete fail­
ure of the brake system.
- T o prevent the veh icle from rolling back
when stoppi ng on incl ines, always hold it
in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipping clutch. The clutch opens auto ­
matically when it becomes too hot from the overload. An indicato
r lamp
ml illu­
minates and a driver message appears
¢ page 112 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving posit io n engaged when
checking under the hood . Make sure the
selector lever has securely engaged and is locked in P w it h the park ing brake set
¢ page 222 . Otherwise, any increase in
eng ine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
(D Note
-S tronic- and tiptronic transmission :
When stopping on an incl ine , do not try
t o hold the vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
peda l to prevent the vehicle from roll ing.
- S tronic- and tiptronic transmission : A l­
lowing the vehicle to ro ll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not l ubricated unde r those cir­
cumstances.
{!) Tips
For safety reasons, the parking brake is re­
l eased automatically only when the d riv­
er's safety belt is engaged in the buckle.

A WARNING ,~ ~
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of
serious personal injury:
- 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.
- Always make sure that there are at least
4 inches (10 cm) between the front pas­
senger's knees and the lower part of the
instrument 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 properly .
- For adjustable head restraints : before
driving, always also adjust the head re­
straints properly .
- 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 seats
¢ page 171. Special precautions apply
Driving Safely 129
when installing a child seat on the front
passenger seat¢
page 145.
Proper seating positions for passengers
in rear seats
Rear seat passengers must sit upright wi th
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 ­
sengers on the rear bench seat must always
observe the following:
... For adjustable head restraints: adjust the
head restraint so the upper edge is as even
as possible with the top of your head . If that
is not possible, try to adjust the head re­
straint so that it is as close to this position
as possible
¢page 130 .
... Keep both feet flat in the footwell in front of
the rear seat .
... Fasten and wear safety belts properly
¢page 139.
... Make sure that children are always properly
restrained in a child restraint that is appro­
priate for their size and age
¢ page 171.
A 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 safety belts are properly
positioned on the body and securely
latched. By not sitting upright, a rear
seat passenger increases the risk of per­
sonal injury from improperly positioned
safety belts!
- For adjustable head restraints: always adjust the head restraint properly so that
it can give maximum protection.
