Please note the important safe­

pressure
¢ page 344 and load
limits
¢ page 347 .
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
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
Wheels
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
luggage 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
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 luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
.,.

Wheels
are listed on the safety compli­
ance sticker on the driver's side B­ pillar respectively on the front
end of the driver's door.
& 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 vehicle's placard
(tire inflation pressure label)
¢ page 344, fig. 277.
2. Determine the combined
weight of the driver and pas­ sengers 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 stick­
er ¢ page 344, fig. 2 77.
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

-If the t ire is too severely damaged , see an
authorized Aud i dealer or authorized Aud i
Service Facility for assistance .
@ For the sake of the environment
You can give the used tire sealant bottle to an
author ized Audi dealer or authorized A udi
Serv ice Facility for disposal.
@ Tips
Remember to obtain a new bottle of sea lant
from an authorized Audi dea ler or authorized
Audi Service Facility after repair ing a tire.

A WARNING
When using the vehicle jack* on a road with a
steep hill or offroad, you must take extra pre­
cautions to prevent the vehicle from rolling .

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­ moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
l ong term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
correct bulbs and the expert ise.
Fuses and bulbs
Gas discharge lamps (Xenon lights) :
Due to the high e lectr ical voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light are identified by the high volt­
age sticker .
LED headlights*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced .
.&, WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
be ing changed. Potential risk of injury!
- On veh icles equipped with gas discharge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
h ig h-vo ltage portions of such lamps!
- Only your authorized Audi dealer or quali­
fied workshop should change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts. If
you are uncertain about what to do, have the work performed by an authorized Audi
dealer or qualified workshop. Ser ious per­
sonal injury may result from improperly per­
formed work.
(D Tips
- If you st ill prefer to replace the light bulbs
yourself, be aware that the engine compart­ ment is a hazardous area to work
in¢ A in
Working in the engine compartment on
page 323.
- It is best to ask your authorized Audi dealer
whenever you want to change a bulb .
