or ridges on the road, particularly if the tire is underinflated .
I n o rder to m inim ize the occu rrence of impact
damage to the t ires of your veh icle, we recom ­
mend that you observe the following precau­
tions :
- Always maintain recommended inflat ion
pressures. Chec k your tire 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
through or over such obstacles can damage
your tires. Impact with a curb may a lso
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 tire failure . If you be lieve that a
t ir e may have been damaged , replace the
t ire as soon as possible.
- T hese tires may wea r mo re qui ck ly than ot h­
ers.
- Please a lso remember that, whi le these tires
deliver respons ive handling, they may ride
l ess comfortably and make mo re noise than
othe r choices.
Reduced performance in winter /cold
season condition s
All tires are des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your veh icle are in­
tended for maximum 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 circums tances, you
should equip your veh icle with all -season or
winter tires, which offer better traction under
those cond itions . We suggest you use the rec­
ommended snow or all-season tires specified
for your ve hicle, or their equ ivalent.

Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith t ire pressure monitoring system
Each tire, incl uding the spare (i f provided),
shou ld be checked monthly when co ld and in ­
flated to the inf lation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle ha s tires of a different size than the
s ize indicated on the vehicle placard or tire i n­
flat ion pressu re labe l, you shou ld dete rm ine
the p roper t ire inflation p ress ure fo r th ose
t ir es).
As an added safety feature , your ve hicle has
been equipped with a tire pressure mon ito ring
system ( TPMS) that illum inates a low ti re
pressure te lltale 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 shou ld 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 hand ling 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
rea ched the leve l to tr igger illum inat ion of the
T PMS low tire p ressure tellta le .
Your vehicle has also been equipped with a
T PMS ma lfunction indicator to ind icate when
the system is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
the low tire pressure te lltale. When the sys­
tem detects a malfunction , the telltale wi ll

The vehicle capac ity we ight (max. load) is list­
ed either on the dr iver's side B-pillar or inside
the fuel filler flap.

.&, WARNING
- T he ac tual Gross Axle Weight Rat ing at
the front and rear axles shou ld not ex­
ceed the permiss ible weights, and their
combination must not exceed the Gross
Vehicle Weight Rat ing .
- Exceeding permissib le weight ratings can
result in vehicle damage, accidents and
personal injury.
CD Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transporting a heavy load in the luggage
compartment, carry the load as near to
the rear axle as possib le so that the veh i­
cle's handling is not impa ired.
- Do not exceed the maximum permissible
axle loads or the maximum gross vehicle
weight. Always remember that the vehi­
cle's handling will be affected by the ex­
tra load. Therefore, adjust you r speed ac ­
cord ingly.
- Always observe loca l regu lations.

Dimensions
The specifications refer to the basic model.
Differences may occur depending on the mod­
el type and options ordered, for example, tire
sizes.
CD Note
When driving up steep ramps, on rough roads, over curbs, etc. it is important to re­
member that some parts of your vehicle,
such as spoilers or exhaust system compo­ nents, may be close to the ground . Be
careful not to damage them .
