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 ve­
hicle is in use.
To reduce the r isk of injury caused by an incorrect
seating position in the event of a sudden braking
maneuver or a n accident, you r passengers on the
rear bench seat must always observe the follow­
in g:
.,. If there are passengers on the outer rear seats,
adjust the head restraints so the upper edge is
as even as possible with the top of your head. If
that is not poss ible, try to adjust the head re­
straint so that it is as close to this position as
poss ible.
If there is a passenger in the ce nte r
rea r seat, slide the head res traint upward
¢page 62.

of injury in an accident by interfering with the
way the airbag deploys or by being pushed in­
to you as the airbag deploys.
- No persons (children) or animals shou ld ride
in the footwell in front of the passenger
seat.
If the airbag deploys, this can result in
serious or fatal injuries .
- No objects of any kind should be carried in
the footwell area in front of the driver's or passenger's seat. Bulky objects (shopping
bags, for example) can hamper or prevent
proper deployment of the airbag. Small ob­
jects can be thrown through the vehicle if
the airbag deploys and injure you or your
passengers.
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.
Make sure that all pedals move freely without in­
terference and that nothing prevents them from
returning to their original positions.
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners.
If a brake circ uit fails, increased brake pedal trav­
e l is required to bring the vehicle to a full stop.
,8. WARNING
-
Peda ls that cannot move freely can cause loss
of vehicle control and increase the risk of seri­
ous injury.
- Never place any objects in the driver's foot­
well. An object cou ld get into the pedal area
and interfere with pedal function. In case of
sudden braking or an accident, you would
not be able to brake or accelerate!
- Always make sure that nothing can fall or
move into the driver's footwell.
Driving safety
Floor mats on the driver side
Always use floor mats that can be securely at­ tached to the floor mat fasteners and do not in­
terfere with the free movement of the pedals .
""Make sure that the floor mats are properly se-
cured and cannot move and interfere with the pedals~ .&_.
Use only floor mats that leave the pedal area un­
obstructed and that are firmly secured so that
they cannot slip out of position . You can obtain
suitable floor mats from your authorized Audi
dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached
to these fasteners. Properly securing the floor mats will prevent them from sliding into posi­
tions that could interfere with the pedals or im ­
pair safe operat ion of your vehicle in other ways .
,8. WARNING
=
Pedals that cannot move freely can result in a
loss of vehicle control and increase the risk of
serious personal injury.
- Always make sure that floor mats are prop­
erly secured.
- Never p lace or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured in place to prevent them
from slipping and interfering with the ped­
als or the ability to control the vehicle.
- Never place or install floor mats or other
f loor coverings on top of already installed
f loor mats . Additional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals.
- Always proper ly reinsta ll and secure floor
mats that have been taken out for cleaning.
- Always make sure that objects cannot fall
into the driver footwell whi le the vehicle is
mov ing. Objects can become trapped under
the brake pedal and accelerator pedal caus­ ing a loss of vehicle control.

Driving safety
Storing cargo correctly
Loading the luggage compartment
All Luggage and other objects must be properly
stowed and secured in the Luggage compart ­
ment.
Fig. 207 Safe load positio ning: place heavy objects as low
and as far forwar d as possible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics . Loose items can also increase the risk of
serious personal injury in a sudden vehicle ma­
neuver or in a collision.
• Distribute the load evenly in the luggage com­
partment.
• Always place and properly secure heavy items in
the luggage compartment as low and as far for­
ward as possible
¢ fig. 207.
• Secure luggage using the tie-downs provided
¢ page 66.
• Make sure that the rear seatback is securely
latched in place .
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per­ sonal injury in the event of hard braking or an
accident . To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always secure objects in the luggage com­
partment using the tie-down eyelets and
suitable straps.
242
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
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 Rating or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the
front end of the driver's door. Exceeding
permissible weight standards can cause the
vehicle to slide and handle differently.
- Please observe information on safe driving
¢page 236.
A 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 area be­
cause the rear lid cannot be fully closed.
- If you absolutely must drive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the sliding sunroof*,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
A WARNING
-
Always make sure that the doors, all win­
dows, the sliding sunroof* and the rear lid are
securely 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 espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
-Air circulation helps to reduce window fog­
ging . 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 label is lo­
cated on the driver's side B-pillar. The tire
pressure label lists the recommended 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 man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter
c:> page 328.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items.
Use the tie-downs to secure your cargo properly
c:> page 242, Loading the luggage compar tment.
In a collision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy 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
Driving safety
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 col­
lision like this.
A WARNING
= -
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from shifting or flying forward as dan­
gerous 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 forward as dangerous
missiles into the passenger compartment.
- Never attach a child safety seat tether strap
to a tie-down.
