gine compartment lid is not secured properly, stop at once and close it.

190 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those standard items which may be rep laced)
of R t ron ic, powe r stee ring, powe r brakes,
power w indows , power sea ts, r ad io , a nd hea t­
e r, to the extent that these i tems are available
as facto ry -in stalled equipment (whether in ­
stalled or not).
Aspect ratio
means t he ratio o f the heigh t to the w idth of
the tire in percen t. Numbers of 55 or lower in­
d icate a low sidewall fo r improved s teer ing re ­
sponse and better overall handling on dry
pavement.
Bead
means t he pa rt of the t ire that is made o f
steel wires, wrapped o r reinforce d by p ly cor ds
and that is shaped to fi t the r im.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the s trands forming the plies in the
tire .
Cold tire inflation pre ssure
means t he tire pressure recommended by the
ve hicle manufacture r for a tire of a designated
si ze that has not been dr iven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure i s measu red or adjusted. -
If you notice un usua l vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
Curb weight
means the we ight of a motor ve hicle w ith
standard equipment includ ing the max imum
capa city of fuel, o il, and coolant, a ir cond i­
ti on ing and addi tional weig ht o f option al
equipmen t.
Extra load tire
means a tire designed to operate at higher
loads and at highe r inflat ion p ress ures tha n
the cor responding standard tire . Extr a load
t ir es my be i dent ified as "XL", "xl", "E X T RA
LO AD", or "RF" on t he sidewall.
Gross Axle Weight Rating ( "GAWR ")
means the load-carry ing capacity of a s ingle
axle system , measured at the tire-ground in­
te rfaces .
Gross Vehicle Weight Rating ( "GVWR ")
means the maximum total loaded we ight of
the vehicle.
Groove
means the space between two adjacent tread
ribs .
Load rat ing (code )
means the maximum load that a tire is rated
to carry fo r a given inflation press ure. Yo u
may not fi nd this information on all tires be­
ca use it is not required by law.
Maximum load rating
me ans the lo ad r ati ng for a tire a t the m axi­
mum perm issib le inf lation pressure for that
ti re .

196 Tires and wheels
wheels you have to adjust the tire pressures
on all wheels.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­ flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat­
ed on a sticker on the driver's side 8-pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system can work cor­
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor­
ing system .
- Always inflate tires to the recommended
and correct tire pressure before driving
off .
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the tire pressure and add
air as required .
(D 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.
@ 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, in­ cluding 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 everybody
and everything in and on the vehicle . These
load limits are technically referred to as the
vehicle 's
Gross Vehicle Weight Rating
("GVWR").
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 ve-
hicle. ..,_

204 Tir es and whe els
eq uip all four wheels on your vehicle with cor ­
rectly fitted winter tires or all-season tires,
when winter road conditions are expected. This a lso improves the vehicle's braking per­
formance and reduces stopping distances.
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four wheels.
Compat ible tire pressure mon itor ing sensors
must be installed on all fou r winter tires for
the tire pressure monitoring system to func­
tion proper ly ~
page 201 .
Ask your authorized Aud i dea ler or qualified
wo rkshop for permitted
winter tir e sizes. Use
only radia l winter tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm) .
Only drive with winter tires under winter con­
d itions . Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remember that w inte r tires may
have a lower speed rating than the t ires origi­
na lly installed on your veh icle at the t ime i t
was manufactured. Please see
r:!> page 200 ,
Speed roting (letter code) for a list ing of the
speed rating letter codes and the maximum
speed at which the tires can be driven.
The speed ra ting letter code
(~ page 191) is
on the s ide wall of the tire
r::!> poge 199.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
im um speed . Always know the maxim um
speed before driving off. Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an accident and serious
personal in ju ry to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your veh icle
were designed can cause t ire failure in­
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per­
sonal injuries. Have wo rn o r damaged ti res
r eplaced immediately.
- W inte r ti res have maxim um speed rating
that may be lower than your vehicle 's
maximum speed.
- Never drive fas ter than the speed for
which the win ter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING ~
A lways ad just your driving to the road and
traffic condit ions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive veh icle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
~ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
S now cha ins may be fitted only to the rea r
whee ls, and o nly to certa in tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow c hains ca n be used.
T he snow chains must have low-profile links
and must not be t hicker than 0 .53 inch
(13 .5 mm), in cl ud ing the lock.
Remove wheel center covers before putt ing
snow c ha ins on your vehicle~@ . For safety
reasons cover caps must then be f itted over

When driving up steep ramps, on rough roads,
over curbs, etc. it is important to remembe r
that some parts of your vehicle, such as spoil­
ers or exhaust system components, may be
close to the ground . Be careful not to damage
them.
This applies especially to vehicles with a low chassis (sports chassis) and when the vehicle
is fully loaded .
