or ridges on the road, part icu larly if the tire is
u nderinflated.
I n o rder to m inim ize the o ccurrence of impact
damage to the t ires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended infla tion
pressures. Check your t ire pressure every
2,000 miles (3,000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h rough or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause t ire failure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, wh ile these t ires
deliver respons ive handling, they may ride
l ess comfortably and make mo re no ise than
other choices.
Reduced performance in winter /co ld
sea son condit ion s
All ti res a re des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or all-season tires specified
fo r your vehi cle, or their eq uivalent. Refer to
q page 22 7 for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, incl uding the spare ( if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the s ize indicated on the vehicle placard or tire in­
flat ion p ressure labe l, you should dete rmine
the p roper t ire infla tion p ress ure fo r those
t i res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPMS) tha t illum ina tes a low ti re
pressure tel ltale when one or more of your
tires is significant ly under-inflated . Acco rding­
l y, when the low tire pressure te lltale i llumi­
nates, you should stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al ­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's handling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low tire pressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf un ction indicator to ind icate when
the sys tem is not operating properly. The
T PMS ma lf u nction indicator is combined w ith
t h e low tire pressure te lltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then ..,_

You will find the compact spare wheel under
the floor in the luggage compartment . It is
secured w ith a large nut.
Using the compact spare wheel
The compact spa re wheel is only intended for
emergenc ies until you can reach a repair shop .
Replace i t as quickly as possible with a normal
wheel.
There are some restrictions on the use of the
compact spare wheel~ &. . The compact spare
wheel has been developed especially for your
type of vehicle . It must not be exchanged for
the compact spare whee l from another type of
vehicle.
Normal summer or winter tires must not be
installed on the compact spare whee l rim.
Snow chains
For technica l reasons, the use of snow chains
on the compact spare wheel is
n ot permitted .
If you do have to dr ive w ith snow cha ins and
have a t ire failure on a
front wheel, insta ll the
spa re wheel in place of a rear wheel. Install
the snow chains on the rear wheel and use it
to replace the defective front whee l.
Using the spare wheel
The spare wheel is only intended for emergen­
cies until you can reach a repair shop. Replace
it as qu ickly as possib le with a no rmal wheel.

Snow t ires
For technical reasons, the use of snow chains
on the spare whee l is
not p erm itte d.
If you do have to drive with snow chains and
have a t ire failure on a
front wheel, insta ll the
spare wheel in place of a rear wheel. Install

the snow chains on the rear whee l and use it
to replace the defective front wheel.
A WARNING -
A lways store jacking equipment, spare
wheel in the luggage compartment. Tight­
en screw for the spare wheel secure ly. Un­
der no circumstances should you store the
spa re wheel o r jack and tools unsecured in
the passenger compartment . This could
cause ser ious persona l inju ry to passen­
gers in the veh icle in case of a collision .
- The compact spare tire is for temporary
use only and is so marked on the side­
walls .
- Do not dr ive at speeds exceeding SO mph
(80 km/h) wi th the compact spare whee l
mounted . A lso rapid acce lerat ion, ha rd
braking and hard cornering must be
avoided to he lp prevent loss of vehicle
contro l.
- Any continuous road use of the compact
spare tire may result in tire failure, loss
of vehicle control and injury to vehicle
occupants.
- Do not put a snow chain on your compact
spare tire. Due to the smaller t ire size,
the chain will not fit properly and can
thus damage your vehicle. You cou ld also
lose the chain, as well as contro l of the
veh icle .
- If you have a flat front t ire in road condi­
tions which require snow chains, first re­
move the undamaged rea r whee l and
mount the compact spare wheel in its
place. Then remove the damaged front
wheel, take the snow cha ins off it and at­
tach them to the whee l taken from the
rear. This wheel can now be mounted on
the front with its snow chains. Check and
adjust t ire pressure promptly .
- Never use two or more compact spare
tires at the same time.
