• in rollover s.
In some types of accide nts the front a irbags a nd side a irbags may be
t rig gere d together.
& WARNING
• Safety belts and the airbag system will only provide prote ction
when occupants are in the proper seating position=> page
219 .
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle acceleration in a side collision is high enough to activate the
airbag. •
How supplemental side airbags work
Side airbags deploy ins tan tly an d can help reduce the risk
o f upper torso injuries for occupants who are properly
restrained.

Wh en the system is trigge red, the airbag is filled w ith prop ellan t gas
and breaks through a seam in the seat s urface area marked
" AIR BAG".
It expand s between the side trim panel and the pa ssenger.
In order to he lp provide this additional protection, the s ide airbag

must inflate w ith in a fract ion of a seco nd at ve ry high speed and w it h
great for ce. T he supp lemen tal side air bag cou ld injure you if yo ur
seating position is not proper or upr ight o r if items ar e located in the
area w here the s upplementa l side ai rbag expands. This applies espe­
cially to children=>
page 221, ''Child Safety" . S upplementa l side
air bags inflate between the occupant and the door panel on the side
of the ve hicl e that is st ruck in certain side collision=> fig. 203 .
Altho ugh they are not a soft pillow, they can "cushion" the impact
and in this way they ca n help to re duc e the ris k of injury to the u pper
part of the body.
A fine dust may develo p when the airbag deploys. This is normal an d
does not mea n the re is a fire in the vehicle. •
Important safety instructions on the side

There is a lot that you and yo ur passengers must k now and act accord­
ingly to help t he safety be lts and a irbags do t he ir job to provide
supplementa l protection.
& WARNING
An inflating side airbag can cau se serious or fatal injury. Improp­
erly wearing safety belts and improper seating position s increase
the risk of serious personal injury and death whenever a vehicle is
being used .
• In order to redu ce the risk of injury when the supplemental
side airbag inflate s:
- Alway s sit
in an upright position and never lean against the
area where the supplemental side airbag is located . •

Tire service Life
The service life of tires depends on a lot of differ ent
things including proper installation and balancing,
corr ect tire pressure and driving style .

Tire pressure
Incorrec t tire pressure causes premature wea r a nd c an cause sudde n
tire blow -o ut. Fo r th is reason, tire press ure must be checked at least
once a mont h =>
page 302.
Driv ing style
Dr iv ing fast aro und curves, he avy ac cele ration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four t ires on your veh icle to have the same se rvice life, we
recommend that the fron t and rear ti re s are rotated according to the
tire ma nufactu rer's suggested tire rotat ion intervals. Please
remember the fo llow ing :
• Tire ro tat ion intervals may d iffe r from the vehicle serv ice intervals
out lined in your Maintenance and War ranty Booklet .
• The longer one tire is used in one locat ion on the vehicle, the more
it wears a t certain points; therefore, we recommend that you follow
the tire manufacture r's suggested tire rotation interva ls .
• Vehicles with front -whee l drive experien ce more tread wear on the
front wheels compa red to all-whee l dr ive (quattro
® ).
• Please ro ta te tires as shown=> fig . 2 30.
• Extra care must be taken when rotating direction-specific tires
=>page 326 .
Wheel balancing
The wheels on new vehicles are balanced . Howeve r, various sit uat io ns
dur ing everyday driving can cause them to become unbalanced,
res ulting in vibr ations yo u can us ua lly fee l throug h the s tee rin g
whee l. •

Unbalanced wh eels must be rebalanced to avoid e xcessive w ear o n
st eeri ng, sus pens ion and tires. A w heel must a lso be re balan ced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrect whee l alignm ent can ca use excessive ti re wea r, impairing
th e safe ty o f the vehicle. If tir es show excessive we ar, ha ve the w heel
alignment checked by a n authorized A udi dealer or qualif ied wo rk ­
s hop .

page 246.
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

Tires and wheels Ill _______________ _____.
than the size indicated on the vehicle placard or tire inflation pressure
label , you sho uld determine the proper tire infla tion pressure fo r
those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressu re monitoring sys tem (TPMS) that illuminates a low tire pres ­
sure telltale when one o r more of your t ires is s ignificantly under­
inflated. Accord ingly, when the low tire pressure tellta le illumi nates,
you should stop and check your tires as soon as possib le, and inflate
them to the proper p ress ure. D riving on a sign ificantly under-inflated
tire causes the tire to overheat and can lead to tire fa ilure . Under­
inflation also reduces f uel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability .
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the d river's responsibility to mainta in correct tire
pressure, even if under-inflation has not reached the level to trigger
ill umination of the TPMS low tire press ure te lltale.
Your vehicle has also been equipped w ith a TPMS malfunction indi­
cato r to indica te when the system is not operating properly . The
TP MS ma lf u nction indicator is combined with the low tire p ress ure
telltale. When the system detects a malfunct ion, the telltale will
fl ash for approximate ly one minute and then rema in continuously
illuminated. This sequence will continue upon subsequent vehicle
sta rt-ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to de tect or signa l low ti re pressure as intended . TPMS
ma lfunctions may occur fo r a var iety of reaso ns, includ ing the instal­
lation of replacement o r alternate tires or wheels on the vehi cle that
prevent the T PMS from functioning properly . Always check the TPMS
ma lfunction tellta le after replacing one or more tires or whee ls on
yo ur vehicle to ensure that the replacement o r alte rnate t ires and
wheels allow the TPMS to continue to funct ion proper ly .•
