Loading the roof rack
Always distribute the Loads evenly . Make sure
anything on the roof rack is tied down secure­
ly.
.. Always distribute the loads on the roof rack
evenly.
.. Always secure items to the roof rack.
The maximum permissible roof weight is
16 5 lb (75 k g). The roof weight is made up of
the weight of the roof rack system and the
weight of the object being transported
.;, page 255.
When using a roof rack system which has a
lower load carrying capacity, you must not use
the total maximum permissible load carry ing
capacity. If th is is the case, you may load the
roof rack system on ly to the maximum capaci­
ty specified by the manufacturer of the roof
rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a coll is ion and
cause ser ious persona l injury.
-Always use suitable mounting straps and
properly secure items to the properly in­
stalled roof rack to help prevent items
from sh ifting or flying forward .
- Items on the roof rack must always be
securely mounted.
- The use of a roof rack can negat ively af­
fect the way a veh icle hand les . Cargo
that is large, heavy, bulky, long or flat
will have a greater negat ive influence on
the vehicle's aerodynamics, center of
grav ity and overa ll handling. Always
drive s lowly, avoid sudden braki ng and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maxim um permissible
load carrying capacity of the roof of your
vehicle, the permissible axle weights and
the permissible total weight of your vehi- cle

ing and maneuvers when transporting
cargo on the roof of your vehicle .
@) For the sake of the environment
Sometimes it may be easier to leave a roof
rack installed even though you are not us­
ing it . Due to the increased a ir resistance
your veh icle will unnecessar ily use more
fuel. Remove the roof rack if you are not
going to use it.

Steering
Adjustable steering wheel
The height and reach of the steering wheel
can be adjusted .
Fig. 101 Lever under the steering column
First, adjust the driver's seat correctly.
• Push the lever
c:> fig . 101 down as far as it
will go
c:> & .
• Move the steer ing whee l to the desired po-
s it ion.
• Push the lever back up as far as it will go.
There must be at least 10 inches (25 cm) be­ tween your chest and the center of the steer­
i ng wheel. If you cannot si t more than 10 in­
ches (25 cm) from the steering whee l, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering whee l.
F or detai led information on how to adjust the
driver's seat, see
c:> page 63, Power seat ad­
justment.
The stee ring wheel can be adjusted even when
the ignition is turned off.
8_ WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
- Always make sure that the ad justment
lever is securely pushed up so that the
-
position of the steering wheel cannot be
changed unintentionally when the vehi­
cle is mov ing.
- Adj ust the driver's seat or steering whee l
so that there is a minimum of 10 inches
(25 cm) between your breastbone and
the steering wheel
c:> page 104,
fig. 117.
If you cannot maintain this
minim um distance, the airbag system
cannot protect you properly.
- If physical limitations prevent you from sitt ing 10 inches (25 cm) or more from
the steering wheel, check wit h your au­
thorized A udi dealer to see if adaptive
equipment is available .
- Pointing the steering wheel toward your
face decreases the ability of the s upple­
mental driver's airbag to protect you in
an accident. Always make sure that the
steer ing whee l is po inted towards your
chest.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock
positions to help reduce the risk of per­
sonal injury if the driver's a irbag inflates .
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steer ing wheel
rim or on the steering wheel hub. Ho ld­
ing the steering whee l the wrong way
can cause se rious inj uries to the hands,
arms and head if the driver's airbag in ­
f lates .

106 Driving Safely
-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 143 . Special precautions
apply when installing a child safety seat
on the front passenger seat
c::> page 122.
Proper seating positions for passenge rs
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
sengers on the rear bench seat must always
observe the following :
.. If there are passengers in the rear seat,
slide the head restraints upward at least to
the next notch on the occupied seats
¢ page 65.
.. Make sure that the seatback is securely
latched in the upright position
c::> page 67 .
.. Keep both feet flat in the footwell in front
of the rear seat.
.. Fasten and wear safety belts properly
c::> page 116.
.. Make sure that children are always properly
restrained in a child restraint that is appro­
priate for their size and age
c::> page 143.
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 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.

108 Driving Safely
- never lean out the window
- never put your feet out the window
- never put your feet on the instrument panel
- never rest your feet on the seat cushion or
back of the seat
- never ride in the footwell
- never ride in the cargo area
A WARNING
Improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used .
-
- Always make sure that all vehicle occu­
pants stay in a proper seating position
and are properly restrained whenever the
vehicle is being used.
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mot
or any other object.
Make sure that all pedals move freely without
interference 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 fasten­
ers.
If a brake circuit fails, increased brake pedal
travel is required to bring the vehicle to a full
stop.
A WARNING
Pedals that cannot move freely can cause
loss of vehicle control and increase the risk
of serious injury.
- Never place any objects in the driver's
footwell. An object could get into the
pedal area and interfere with pedal func­
tion. In case of sudden braking or an ac­
cident, you would not be able to brake or
accelerate!
- Always make sure that nothing can fall
or move into the driver's footwell.
Floor mats on the driver side
Always use floor mots that con be securely
attached to the floor mot fasteners and do
not interfere with the free movement of the
pedals.
.,. Make sure that the floor mats are properly
secured and cannot move and interfere with
the pedals ~.&_ .
Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so
that they cannot slip out of position . You can
obtain suitable floor mats from your author­
ized Audi Dealer.
Floor mat fasteners are installed in your Audi .
Floor mats used in your vehicle must be at­
tached to these fasteners. Properly securing
the floor mats will prevent them from sliding into positions that could interfere with the
pedals or impair safe operation of your vehicle
in other ways.
_&. 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
properly secured.
- Never place 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 pedals or the ability to control the
vehicle.
- Never place or install floor mats or other
floor coverings on top of already instal­
led floor mats. Additional floor mats and
other coverings will reduce the size of
the pedal area and interfere with the pedals .
- Always properly reinstall and secure floor
mats that have been taken out for clean­
ing.
- Always make sure that objects cannot fall into the driver footwell while the ve-
hicle is moving. Objects can become
~

trapped under the brake pedal and accel­
erator pedal causing a loss of vehicle
control.

A 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
injury:
-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 We ight Rat­
ing or the G ross Vehicle Weight Rating
specif ied on the safety compliance stick­
er on the left door jamb. Exceeding per­
miss ible weight standards can cause the
veh icle to slide and handle different ly.
- Please
observe informat ion on safe driv­
ing¢
page 103.
A WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always
ke ep the rear lid clos ed w hile driving.
- Never transport objects larger than
those fitting completely into the luggage area because the rear lid cannot be fu lly
closed .
- I f you absolutely must dr ive with the rea r
lid open, o bserve the following no tes to
red uce the risk of poison ing:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument
panel,
- Swi tc h off the air rec irculat ion,
- Set the fresh air fan to the highest
speed.

110 Driving Safely
&_ WARNING
Always make sure that the doors, all win­dows, the power roof* and the read 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 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
- The tire pressure must correspond to the
load -see the tire pressure sticker on the
fuel filler door.
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. On USA vehicles, the
tire pressure label is located on the driv­
er's side B-pillar. On Canada vehicles, the
tire pressure label is located either on
the driver's side B-pillar or inside the fuel
filler flap. 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 manu­
factured. For recommended tire pres­
sures for normal load conditions, please
see chapter ¢
page 216.
-
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 prop­
erly
¢ page 109, Loading the luggage com ­
partment .
In a collision, the laws of physics mean that
even smaller items 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.
&_ 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.
