-Please observe information on safe driving
~page 130.
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 power roof*,
- 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 windows,
the power roof* 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.
(D Tips
- 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.
Driving safety
-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 ~
page 224.
' 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
~page 136, Loading the luggage compartment.
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
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

Always remember, a chi ld seat or infant carrie r
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's a irbag in a frontal collision . The air­
bag could greatly reduce the effectiveness of the
child restraint and even ser iously injure the ch ild
during inflation .
For this reason, and because the back seat is the
safest place for ch ildren -when properly restrain­
ed according to their age and s ize -we strongly
recommend that ch ild ren always s it in the back
seat
¢ page 172, Child safety .
A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat w ill be seri­
ously in jured and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
- T he inflating a irbag w ill hit the child seat or
infant carrier w ith great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
-
- Always install rear -facing child seats on the
rear seat.
- If you mus t install a rearward facing child
seat on the front passenger seat beca use of
exceptional circ umstances and the

and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the a irbag system inspected by
yo ur Audi dealer.
- Forward-fac ing ch ild seats installed on the
front passenger's seat may interfere with
the deployment of the airbag and cause se­ rious persona l injury to t he ch ild.
A WARNING
If, in exceptional c ircumstances, you mus t in­
stall a forward-facing ch ild restraint on the
front passenger's seat :
- Always make sure the forward-fac ing seat

senger front and s ide a irbag.
- Never put t he fo rward-facing child restraint
up aga inst or very near the instrument pan­
el.
- Always move the passenge r seat into its
rearmost pos ition in the seat's fore and aft
ad justment range, as far away from the a ir­
bag as possible before installing the for­
ward-facing child restraint. The backrest
m ust be adjusted to an upr ight position .
- Make sure that the

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dea ler or au ­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equ ipped with
the required tools and replace­
ment parts .
.,,. New tires do not yet have the
opt imum adhesion properties .
Drive carefully and at moderate
speeds for the first 350 m iles
(500 km) with new tires .
.,,. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as possible on all four
wheels .
Tires a nd whe els
.,,. Do not replace tires individually.
At least replace both tires on the same axle at the same time .
.,,. Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires
may perform different ly even if
they are the same size
c:::> ,& .
.,,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­ sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase
c:::> ..1,. .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel d riv e vehicles, all
four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the drive system is not damaged by
22 1

Tires and wheels
different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular tires.
.&,. WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size . If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than 6 years old when abso-
222
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.

& WAR NING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other acc ident, 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 in­ crease 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 -
inc luding 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.
Step s for Determining Correct
Load Limit
1. Locate the statement "THE
COMBINED WE IGHT OF OCCU ­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
L BS"on your vehicle's placard
(tire inflation pressure label)
¢ page 224, fig . 170 .
2. Determine the combined
weight of the drive r and pas­
sengers that will be riding in
your vehic le.
3. Subtract the combined weight of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 224, fig . 170 .
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 will ...
