_& 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 a loss of vehicle con­
tro l.
- The brakes on a veh icle 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 causi ng loss of con­
tro l and a crash.
- Always make sure that the total load be­
ing transported -including the we ight 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.
A WARNING
-Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­ dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
-
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­
lar .
The recommended tire pressures are on the
tire pressure label and in the table
¢ page 234, Cold tire inflation pressure .This
means that the pressure m ust be checked and
adjusted when the tire has not been driven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "co ld ."
It is the inflation pressure in a "cold" tire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendations ¢
page 234. The
tires would then be underinflated and could
fail suddenly .
The tire pressure label on your Audi lists the
recommended cold tire inflation pressures at
maximum capacity for the new, original
equipmen t tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the labe l
¢page 234, fig. 174.
Most tires lose air naturally over t ime. They
can also lose some air if yo u drive over a pot­
hole or hit a curb while parking. It is usually
not possible to see whether the radial tires
used today are underinflated just by looking
at them.
T here fore, be sure to check ti re pressures at
least once a month and a lways before going
on a long trip . Make sur e to take the number
of peop le and the amount of luggage into ac­
count when adjust ing tire pressure for a trip -
even one that you would not consider to be
"long ." See ¢
page 238, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflat ion pres­
sures. Check all of the tires and be sure not to
forget the spare tire.
If the pressure in any tire
i s too h igh when the tire is "cold", let air out
of the tire slowly with the edge of the tire
gauge and keep check ing the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the cold .,..

252 What do I do now?
has been designed specifically fo r you r type of
vehicle . It must not be swapped with a com­
pact spare t ire from another type of veh icle.
Snow cha ins
F or technical rea son s, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare whee l w ith
tire instead of a rear t ire. Install the snow
cha ins on the rear tire and use it to rep lace
the defective front tire .
A WARNING
-Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
treme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and tire.
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
compact spa re tire must be 4.2 bar; oth­
erw ise, you risk hav ing an accident.
- Do not drive faster than SO mph (80 km/
h). You risk having an acc id ent.
-Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . You risk hav­
ing an acc ident.
- Never drive us ing more than one spare
wheel and tire. You risk having an acci­
dent .
- Normal summer or winte r tires must not
be mounted on the compact spare whee l
rim.
- For technical reasons, the use of ti re
c hains on the spare tire is not permitted.
If it is necessa ry to dr ive wi th tire ch ains,
the spare whee l must be mounted on the
front axle in the event o f a f lat in a rear
t ir e. The newly ava ilable front wheel
must then be installed in place of the rear whee
l with the flat tire. Installing
the t ire cha in before mounting the whee l
and tire is recommended.
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard brak ing or in an accident.
Never store the inflatable spare tire or
jack and tools in the passenge r compart­
ment.
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 t ire failure, p ull the
