A WARNING
-
Drivers who are unbelted, out of position or
too close to the airbag can be se riously in­
jured by an airbag as it unfolds. To help re­ duce the risk of serious personal injury:
- Always ad just the driver's seat and the
steer ing whee l so that there are at least
10 inc hes (25 cm) between you r breastbone
and the steer ing wheel.
- Always ad just the d river's seat and the
steer ing wheel so that there are at least
4 inches (10 cm) between the knees and the
lowe r part of the instrument panel.
- Always hold the steering w heel on the out­
side of the steering wheel r im with yo ur
hands at the 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- N ever hold the stee ring wheel at the
12 o' clock position o r wi th yo ur hands at
other posi tions i nside the steer ing whee l
rim or on the steering wheel hub . Holding
the steering wheel the wrong way can cause
serio us injuries to the hands, arms and head
if the dr iver's airbag inf lates .
- Pointing the steering wheel toward your

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 noth ing prevents them from
return ing to the ir original positions .
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners.
If a brake circuit fails, increased brake peda l trav­
e l is required to bring the vehicle to a full stop.
A WARNING
Peda ls that cannot move free ly 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 could get into the pedal area and interfere w ith pedal function . In case of
sudden braking o r an accident, you would
not be able to brake or accelerate!
- Always make sure that nothing can fall or
move into the dr iver's footwe ll.
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 pos it ion . You can obtain
suitab le floo r mats from your autho rized Aud i
Dea le r.
F loor mat fasteners are installed in your Audi.
Fl oor mats used in your vehicle must be attached
u. ~ to these fasteners. Properly securing the floor

ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat.
The additional padding will prevent the
weight-sensing mat in the seat from accu­
rately registering the child restraint or per­
son on the seat and prevent the Advanced
Airbag System from functioning properly .
- If you must use a child restraint on the front
passenger seat and the child restraint man­
ufacturer's instructions require the use of a
towel, foam cushion or something else to properly position the child restraint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position and have the airbag system inspected by
your Audi dealer .
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-point safety belts and the adjustable head restraints to help reduce the risk of injury in
a wide range of accident and crash situations . Be
sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de­ pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit. Crash severity depends on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side , regardless of safety belt
use, the airbag will be turned off if the weight on
~ the passenger seat is less than the amount pro-...,
~ gram med in the electronic control unit. The front N
8 airbag on the passenger side will also be turned 0 :c ' Airbag system
off if one of the child seats that has been certi­
fied under Federal Motor Vehicle Safety Standard
208 has been recognized on the seat. The
PAS­
SENGER AIR BAG OFF
light comes on and stays
on to tell you when the front Advanced Airbag on
the passenger side has been turned off
~ page 228, Child restraints on the front seat ­
some important things to know .
_&. WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­
ting sideways or out of position in any way,
your risk of injury is much higher .
- You will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates
-
even with an Advanced Airbag~ page 227.
More important things to know about front
airbags
Fig. 231 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­ plemental protection in a frontal collision .
The front airbags are designed to provide addi­
tional protection for the chest and face of the driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag,
- and the head restraints have been properly ad-
justed .

sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
l uggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
296
carried in the vehicle (including
the weight of a trailer hitch and the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as l uggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 293,
fig. 266.
_& WARNING ~
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.

-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­ ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS " on your vehic le 's placard
(tire inflation pressure label)
¢ page 293, fig. 266 .
Wheels
2. Determine the combined
weight of the driver and pas­sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 293, fig . 266 .
4. The resulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
"XXX" amount
equals
1400 lbs. and there wil l
be five
150 lbs . passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 X 150) = 650
lbs .)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­
ceed the available cargo and
luggage load capacity calculat­
ed in Step 4.

Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING -
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-Volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
