Determining correct load
Talis
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 266, fig. 168.
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 sticker
=> page 266, fig. 168.
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
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.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
>Check the tire sidewall
(=> page 257, fig. 165) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

Emergency assistance

Inflating a tire
> Move the switch (8) > fig. 172 on the compres-
sor into position I.
> Inflate the tire to between 29 psi (200 kPA)
and 36 psi (250 kPA) and read the pressure on
the gauge.
> If this tire pressure is not reached, remove the
filler hose. Drive slowly approximately 33 feet
(10 m) forward or in reverse so that the sealant
can be distributed in the tire. Inflate the tire
again > A\.
Z\ WARNING
— Read and follow the manufacturer's safety
precautions on the compressor and in the in-
structions on the bottle of sealant.
— Ifa tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not con-
tinue driving.
— If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au-
thorized Audi Service Facility for assistance.
G) Tips
Do not operate the compressor for more than
six minutes continuously, or it can overheat.
Once the compressor has cooled, you can con-
tinue to use it.
Completing
Applies to: vehicles with tire mobility kit


> Affix the sticker that says "max. 50 mph (max.
80 km/h)" that is provided with the tire mobili-
ty kit within the driver's field of vision.
> Stop the vehicle after driving for about 10 mi-
nutes and check the tire pressure.
> If the tire pressure is lower than 19 psi (130
kPA), then the tire is too severely damaged. Do
not continue driving.

ZA WARNING
Pay attention to the following after repairing
the tire:
— Do not drive faster than 50 mph (80 km/h).


— Avoid hard acceleration or braking and driv-
ing fast around curves.
— The vehicle may become more difficult to
control.
— If the tire is too severely damaged, see an
authorized Audi dealer or authorized Audi
Service Facility for assistance.

@) For the sake of the environment
You can give the used tire sealant bottle to an
authorized Audi dealer or authorized Audi
Service Facility for disposal.
@ Tips
Remember to obtain a new bottle of sealant
from an authorized Audi dealer or authorized
Audi Service Facility after repairing a tire.
Replacing wheels
You must complete the preparation before
changing a tire.
> Read and follow the important safety precau-
tions > page 286.
> Set the parking brake.
> Select the “P” position.
> When towing a trailer: disconnect the trailer
from your vehicle.
> Lay out the vehicle tool kit > page 286 and the
spare tire > page 292.
> Applies to: vehicles with air suspension: Select
on the home screen: VEHICLE > Settings &
Service > Air suspension: wheel change.
> Switch the ignition off.

A WARNING
— The vehicle must also be secured to prevent
it from rolling when using the vehicle jack*.
Use suitable objects to block the front and
back of the wheel that is diagonal from the
wheel with the flat tire.
— Applies to: vehicles with active roll stabiliza-
tion: Switch the ignition off because the sus-
pension regulation could change the vehicle |>
