A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal 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 con­
trol.
- 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 overload ­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
-Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port 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 OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure
label)¢
page 247,
fig. 200.
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 247, fig. 200.
4. The resulting figure equals the available amount of car­
go and luggage load capaci­
ty. For example, if the "XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­ pacity is 650 lbs. (1400-7 50
(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 trail­
er will be transfe rred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle.
... check the tire sidewall
(q page 254, fig. 204) to de­
termine the de signated load
rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

ing on the make, t here will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for examp le "TWI" or other
symbols) indicate the positions of the tread
wear indicato rs . Worn tires must be rep laced .
D iffere nt figures may apply in othe r countr ies
~ A .
Tire pressure
Incorrect t ire pressure causes premature wear
and can cause sudden tire blow-out. For this reason, tire pressure must be checked at least
once a month ¢
page 249.
Driving style
Driving fast around curves, heavy acce lerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires a re rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­ ing:
- Tire rotation intervals may differ from the
veh icle service interva ls outlined in your
Warra nty
& Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend t hat you
follow t he tire manufacturer's suggested
tire rotation intervals.
- Veh icles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pared to all-wheel drive (quattro).
- Please rotate tires as shown ¢
fig. 203.
- Extra care must be taken when rotating di-
rection-specific tires¢
page 2 71 .
Wheel balancing
The wheels on new veh icles are balanced.
However, various situations during everyday
driv ing can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steer ing wheel. ..,.

266 What do I do now?
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang ­
ing 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 o ,&.
... All passengers should leave the car and
move to a safe location (for instance, behind
the guardrail)
o A-
.. Engage the parking brake to prevent your
vehicle from rolling unintentionally
o ,&.
... Move selector lever to position Po ,& .
• If you are towing a trailer, unhitch the trailer
from your vehicle .
... Take the
jack and the spare tire out of the
luggage compartment
o page 264,
o page265.
A WARNING
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire,
move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- 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
sudden ly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed . When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in P
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm.
If necessary,
use a sturdy board under the jack.
-
-Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment

@ Tips
Before changing the whee l, you must acti­
vate the jacking mode, so that the auto­
matic controls for the Adaptive Air Sus­
pension* do not make it more difficult to
lift the vehicle with the jack
