Tires and wheels -
----------------
•
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To prevent this, always make sure that factory installed valve
stem caps on all wheels are securely mounted on the valve .
W For the sake of the environment
Underinflated tires will also increase the fuel consumption. •
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 also 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 passengers also depends on making
sure that load limits are not exceeded. Vehicle load includes every­
body and everything in and on the vehicle. These load limits are
technically referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"l.
The "GVWR" includes the weight of the basic vehicle, all factory
installed accessories, a full tank of fuel, oil , coolant and other fluids
plus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating position 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 included as part of the
vehicle load.
The
Gross Axle Weight Rating ("GAWR"l is the maximum load that
can be applied at each of the vehicle's two axles. The
Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compliance sticker label located either on
the driver's side 8-pillar or on the inside of the fuel filler flap. Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Vehicles with power individual rear seats*
have 4 seating positions, 2 in the front and 2 in the rear for total
seating capacity of 4. Each seating position has a safety belt
~ page 211, "Safety belts".
The fact that there is an upper limit to your vehicle's Gross Vehicle
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 passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure label on your Audi also lists the maximum
combined weight of all of the occupants and luggage or other cargo
that the vehicle can carry. For the location of the label
~ page 330,
fig. 274.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal 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 suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer 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 calculate the
total weight of the passengers and
luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct
Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label)=> page 330, fig. 274.
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" kilo­
grams or "XXX" pounds shown on the
sticker=> page
330, fig. 274. 4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, 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
exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidewall (=> page
338,
fig. 278) to determine the designated
load rating for a specific tire. •

What do I do now? Ill
---------------~.;______
•
-Disengage and lower the floor panel before you close the
luggage compartment lid again.
Storing the replaced wheel
-Place the replaced wheel inside the spare wheel well in
the luggage compartment.
Tighten the knurled retaining screw clockwise to secure
the wheel in place.
- Disengage and lower the floor panel before you close the
luggage compartment lid again.
& WARNING
Loose items in the passenger compartment can cause serious
personal injury during hard braking or in an accident .
• Never store the spare wheel or jack and tools in the passenger
compartment.
• Always store all jacking equipment, tools, and the spare wheel
in the luggage compartment.
• Tighten the knurled retaining screw for the spare wheel
securely.
[ i] Tips
Check the inflation pressure of the spare tire periodically to keep the
tire ready for use. •
Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
- After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop
~ & .
- All passengers should leave the car and move to a safe
location (for instance, behind the guardrail) ~& .
- Engage the parking brake to prevent your vehicle from
rolling unintentionally ~& .
- Move selector lever to position P
~ &.
-If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the jack and the spare tire out of the luggage
compartment~
page 351.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flashers on and use other warning
devices to alert other motorists.
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed. When one ..,
