A 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  the  loss  of  vehicle con
trol. 
- The  brakes  on  a vehicle  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,  including  a  blowout 
and  sudden  deflation,  causing  loss of 
control  and  a crash. 
- Always  make sure  that  the  total  load  be
ing  transported  -including  the weight  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. 
Determining  correct  load  limit 
Use the  example  below  to  cal
culate  the  total  weight  of the 
passengers  and  luggage  or  oth
er things  that  you  plan  to  trans
port  so that  you can  make  sure 
that  your  vehicle  will not  be 
overloaded. 
Steps for  Determining 
Correct  Load Limit 
1.  Locate the  statement  "THE  COMBINED WEIGHT OF QC-
Tires  and  wheels  249 
CUPANTS AND CARGO 
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your  ve
hicle's  placard  (tire  inflation 
pressure  label) 
¢ page 244, 
fig. 195. 
2.  Determine  the  combined  weight  of the  driver  and  pas
sengers  that  will be  riding  in 
your vehicle. 
3.  Subtract  the  combined  weight  of the  driver  and  pas
sengers  from 
"XXX" kilo
grams  or 
"XXX" pounds 
shown  on the  sticker 
¢page 244, fig. 195. 
4.  The  resulting  figure  equals 
the  available  amount  of car
go  and  luggage  load  capaci
ty.  For example,  if the 
"XXX" 
amount  equals  1400  lbs. 
and  there  will be five  150  lbs.  passengers  in your  vehi
cle,  the  amount  of available 
cargo  and  luggage  load  ca pacity  is 650  lbs.  (1400-7  50 
(5 
X 150) = 650  lbs.) 
5.  Determine  the  combined  weight  of  luggage  and  cargo 
being  loaded  on the  vehicle. 
That  weight  may  not  safely  exceed  the  available  cargo

Tire service life 
The service  life  of  tires  depends  on  a lot  of 
different  things  including  proper  installation 
and  balan cing,  correct  tire pressure  and  driv
ing  style.

¢ fig.  197 ru nning  across the  tread . Depend
ing  on the  ma ke, there  will  be six to  eight  of 
them  even ly placed  aro und the  tire.  Marks  on 
the  tire  sidewall  (for  example  "TWI" or  other 
symbols)  ind icate  the  positions  of  the  tread 
wear  indica to rs. Wor n tires  must  be replaced . 
Different  figures  may  apply  in other  countr ies 
¢ .&_ . 
Tire  pressure 
Incorrect  t ire pressure  causes premature  wea r 
and  can cause sudde n tire  blow-out . For this 
reason,  tire  pressu re must  be checked at  least 
o nce a month 
¢ page  246 . 
Driving  style 
Driving  fast  around  c urves , heavy accelerat ion 
and  hard  braking  increase tire  wear . 
Rotating tires  for  more  even wear 
F or  all  four  tires  on your  ve hicle to  have the 
same  service  life,  we  recomme nd that  the 
front  and  rear tires  are  rotated  accord ing to 
the  tire  manufact urer's  suggested  tire  rota
tion  intervals.  Please remembe r th e follow
i ng: 
- T ire rotation  intervals  may  differ  from  the 
veh icle service  intervals  o utli ned  in your 
Warranty 
& M ain tena nce booklet. 
- The  longer  one  tire  is  used  in one  location 
on t he vehicle,  the  more  it  wears  at  certain 
points;  the refore , we  recommend  that  you 
follow  the  tire  man ufac turer's  suggested 
tir e rotat ion  intervals. 
- Ve hicles w ith  front -wheel  dr ive experience 
more  trea d wear  on the  fro nt  wheels  com
pa red to  all-wheel  d rive (q uattro). 
- Please rotate  tires as  shown ¢ 
fig. 198 . 
-Extra  care must  be taken  when  rotating  di-
rection -spec ific  tires ¢ 
page  268 . 
Wheel  balancing 
The wheels  on  new  ve hicles are balanced . 
However,  various  s ituations  during  everyday 
driv ing can cause them  to  become 
...  
Page 253 of 304

unbalanced, resulting  in vib rations  you  can 
usually  feel  through the  steering  wheel. 
Unba lanced  wheels  mus t be  rebalanced  to 
avoid  excessive  wea r on  s teer ing,  suspens ion 
and  tires.  A wheel  must  a lso  be  rebalanced 
when  a  new  tire  is  installed. 
Incorrect  wheel alignment 
Inco rrect  whee l alignment  can  cause  exces
sive  tire wea r,  impair ing  t he safety  of the  veh i
cle.  If  t ires  show  excess ive wear,  have  the 
wheel  alignment  checked  by an  authorized 
Audi dealer  or  qualified  workshop. 
All-wheel  d rive 
Ve hicles  w it h  quattro  must  always  have  tires 
of the  s ame  s ize,  construction  and  tread  type.

A WARNING 
Sudden  tire  failure  can  lead  to  loss  of  con
trol,  a  crash  and  serious  persona l injury! 
- Never  drive  a  veh icle  when  the  tread  on 
any  t ire  is worn  down  to  the  wear  indica
tors. 
- Worn  tires  are  a safety  hazard , they  do 
not  grip  well  on  wet  roads  and  increase 
your  risk of"hydrop lan ing"  and  loss  of 
co ntrol. 
- 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 
sp eeds. 
- Never  mount  used  tires  on yo ur vehicle  if 
yo u are  not  sure  of their  "previous histo
ry." Old used  ti res  may  have  been  dam
aged  even  though  the  damage  cannot  be 
seen  that  can  lead  to  s udden  tire  failure 
and  loss  o f vehicle  control.

¢ ,& . 
We recommend  that  all  work  on  tires  and 
wheels  be perfo rmed  by an authorized  Audi 
dea ler. They are familiar  with  recommended 
proced ures and  have the  necessary spec ial 
too ls and spare  parts  as well  as the  proper  fa
cilities  for  disposing  of  the  old  tires. 
Authorized  Audi  dealers  have the  necessary  information  about  techn ica l requ irements  for 
installing  or  changing  tires  and  r ims. 
Re placing t ires  and  whe els 
Tires sho uld be rep laced at  least  in  pairs  and 
not  individua lly (for  examp le both  front  tires 
or  both  rear tires  together). 
Be sure to  read and heed the  information  to 
the  tire  pressure  monitoring  system* 
¢page  258. 
Always buy rep lacement  radial  tires  that  have 
the  same specifications  as the  tires approved 
for  your  vehicle  by Audi.  Replacement  t ires 
must  always have the  same  load rating  speci
fication  as the  original  equipment  or  approved 
optional  tires  listed  in the  table

254  Tires  and wheels 
Driving with  different  tires  reduces  vehi
cle  handling  and  can lead to  a  loss  of 
control. 
- I f  the  spare  tire  is not  the  same  as  the 
tires  that  are  mounted  on the  vehicle  -
for  example  with  winter  tires  - only use 
the  spare  tire  for  a short  period  of time 
and  drive with  extra  care . Refit the  nor
mal  road  wheel  as  soon  as  safely  possi
ble. 
- Never drive faster  than  the  maximum 
speed  for  which  the  tires  on your vehicle 
are  rated  because  tires  that  are  driven 
faster  than their  rated  speed  can  fail 
suddenly. 
- Overloading  tires  cause  heat  build-up, 
sudden  tire  failure, including  a blowout 
and  sudden  deflation  and  loss  of  control. 
- Temperature  grades  apply to tires  that 
are  properly  inflated  and  not  over  or  un
derinflated . 
- For  technical  reasons  it  is not  always 
possible  to  use wheels  from  other 
vehicles  -in  some  cases  not  even wheels 
from  the  same  vehicle  model. 
- If you  install  wheel  trim  discs  on the  ve
hicle wheels,  make  sure  that  the  air flow 
to  the  brakes  is not  blocked.  Reduced  air
flow to  the  brakes  can them  to  overheat,  increasing  stopping  distances  and  caus
ing  a collision . 
- Run flat  tires  may only be  used  on 
vehicles  that  were  equipped  with  them 
at  the  factory . The vehicle  must  have a 
chassis  designed  for  run flat  tires . Incor
rect  use  of  run flat  tires  can  lead to  vehi
cle damage  or  accidents.  Check with  an 
authorized  Audi  dealer or tire  specialist 
to  see  if your  vehicle  can  be  equipped 
with  run flat  tires.  If  run flat  tires  are 
used,  they  must  be  installed  on  all four 
wheels . Mixing tire  types  is not  permit
ted . 
(D Note 
-For technical  reasons,  it is not  generally 
possible  to  use the  wheel  rims  from  oth- er  vehicles. 
This can  hold  true  for  wheels 
of the  same  vehicle  type. 
- If the  spare  tire  is different  from  the 
tires  that  you  have mounted  on your ve
hicle  (for example  winter  tires  or wide 
profile  tires),  then  use  the  spare  tire  for a 
short  period  of  time  only and  drive with 
extra  care.  Replace the  flat  tire  with  the 
tire  matching  the others  on your vehicle 
as  soon  as  possible . 
- Never drive without  the  valve stem  cap . 
The  valves  could  get  damaged . 
® For the  sake of  the  environment 
Dispose  of  old tires  in accordance  with  the 
local  requirements. 
Uniform  tire  quality  grading 
-Tread wear 
- Traction  AA A B C 
- Tempe ra ture  ABC 
Quality grades  can  be found  where  applicable 
on  the  tire  side  wall  between  tread  should er 
and  maximum  section  width 
c;, page  251, 
fig. 199. 
For example: 
Tread wear 200, Traction AA, 
Temperature A. 
All passenger  car tires must  conform  to  Feder
al  Safety  Requirements  in addition  to  these 
grades. 
Tread wear 
The tread  wear grade  is a comparative  rating 
based  on the  wear  rate  of  the  tire when tested 
under  controlled  conditions  on  a specified 
government  test  course. 
For example,  a tire  graded  1S0  would  wear 
one  and  one  half  (11/2)  times as  well  on  the 
government  course  as  a tire  graded  100. 
The relative  performance  of  tires  depends  upon  the  actual  conditions  of  their  use,  how
ever, and  may  depart  significantly  from  the 
norm  due  to variations  in driving  habits,  serv
ice practices  and  differences  in road  character-
istics  and  climate.

Traction 
The traction grades,  from  highest  to  lowest, 
a re AA,  A, Band 
C. Those  grades  represent  the 
tire's  ability to  stop  on wet  pavement  as 
measured  under  controlled  conditions  on 
specified  government  test  surfaces  of asphalt 
and  concrete . A tire  marked  C may have poor 
traction  performance¢ .&.. 
Temp eratu re 
The temperature grades  are  A (the  highest), 
B,  and 
C, representing  the  tire 's resistance  to 
the  generat ion of heat  and  its ability to  dissi
pate  heat  when  tested  under  controlled  condi
tions  on a specified  indoor  laboratory  test 
wheel. 
Sustained  high temperature  can cause  the 
material  of the  tire to  degenerate  and  reduce 
tire  life, and  excessive temperature  can lead 
to  sudden  tire  failu re ¢ .&. . 
The grade  C corresponds  to  a level of perform
ance which all passenger  car tires  m ust  meet 
u nder the  Federa l Motor Ve hicle Safety Stand
ard  No. 
1 09. Grades Band  A represent  higher 
l eve ls of pe rformance  on the  laboratory  test 
wheel than  the  m inimum  required  by law. 
_& WARNING 
Th e traction  grade  assigned  to  this  tire is 
based  on stra ight-ahead  b raking t raction 
tests,  and  does  not  include acceleration, 
cornering , hydrop laning  or  peak traction 
character istics. 
A WARNING 
The temperature  grade  for  this  t ire  is es 
tablished  for  a t ire that  is properly inflated 
and  not  overloaded.  Excessive speed,  un
derinflation,  or excessive loading,  either 
separate ly or in combination,  can cause 
heat  buildup  and  possibl e tire  fa ilu re.

Winter  tires 
Winter  tires can improve  vehicle handling  on 
snow  and  ice . At  temperatures  below  45  °F 
(7 °C) we recommend  changing  to  winter 
tires. 
In some  heavy snow areas,  local governments 
may require  true w inter  o r "snow"  tir es,  those 
with very deeply cut  t read.  These  tires  should 
o nl y be used  in pairs  and  be installed  o n all 
f o ur wheels . Make sure you p urchase  snow 
ti res  that  are  the  same  size and  cons truc tion 
type  as  the  other  tires  on yo ur vehicle . 
I f your veh icle is eq uipped  w ith  all-whee l 
drive *, t his w ill improve trac tion  durin g w in ter 
driv ing, even wi th the  s tanda rd tires.  Howev 
er, we strongly  recommend  that  you always 
equip  all four wheels  on your veh icle w ith  cor
rect ly fitted  winter  tires  or all-season  t ires, 
when winter  road  condit ions  are  expected.

A WARNING 
Winter  tires  have maximum  speed  limits 
that  may be lower  than  your  vehicle's  max
imum  speed . Always  know  the  maximum 
speed  before  driving  off.  Never drive  faster 
than  the  speed  permitted  for  your  specific 
winter  tires.  This will  cause damage  to  the 
tires  leading  to  an accident  and serious 
personal  injury  to  you  and your  passen
gers. 
A WARNING I>= 
Driving  faster than  the  maximum  speed 
for  which  the  winter  tires  on your  vehicle 
were  designed  can cause tire  failure  in
cluding  a blowout  and sudden  deflation, 
loss of  control,  crashes and serious  per
sonal  injuries.  Have worn  or  damaged  tires 
replaced  immediately. 
- Winter  tires  have maximum  speed  rating 
that  may be lower  than  your  vehicle's 
maximum  speed . 
- Never drive  faster  than  the  speed for 
which  the  winter  or  other  tires  installed  on your  vehicle  are rated. 
A WARNING 
Always adjust  your  driving  to  the  road  and 
traffic  conditions.  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  vehicle 
handles  in the  same way as  a front  drive 
vehicle. 
- Drive carefully  and reduce your  speed on 
icy and slippery  roads, even winter  tires 
cannot  help  under  black  ice conditions. 
@) For the  sake of the  environment 
Use summer  tires  when  weather  condi
tions  permit.  They  are quieter,  do  not wear 
as quickly  and  reduce fuel  consumption. 
Snow chains 
Snow chains  may be fitted  only  to  the  front 
wheels,  and only  to certain  tire  sizes . Ask your 
authorized  Audi  dealer  on  which  tire  sizes  snow  chains can be used. 
If  you are going  to  use snow  chains, then  you 
must  install  them  on the  front  wheels  at 
least. 
The  snow  chains must  have  low-profile links 
and  must  not be thicker  than  0.4  inch 
(10,5  mm) , including  the  lock. 
Remove wheel  center  covers and trim  discs 
before  putting  snow  chains on your  vehicle 
¢ (!) . For  safety  reasons cover caps must  then 
be fitted  over the  wheel  bolts.  These are avail
able  from  authorized  Audi  dealers. 
A WARNING 
= 
Using the  wrong  snow  chains for  your  vehi-
cle  or  installing  them  incorrectly can in
crease the  risk of  loss of  control  leading  to 
serious  personal  injury. 
- Snow chains are available  in different 
sizes . Always  make sure to  follow  the  in
structions  provided  by the  snow  chain  manufacturer. 
- When  driving  with  snow  chains  never 
drive  faster  than  the  speed  permitted  for 
your  specific  snow  chains. 
- Always observe  local  regulations. 
(D Note 
- Remove snow  chains  before driving  on 
roads  not  covered with  snow to  avoid 
damaging  tires  and wearing  the  snow 
chains down  unnecessarily . 
- Snow chains, which  come  into  direct  con
tact  with  the  wheel  rim,  can scratch  or  damage  it.  Therefore,  make sure that  the 
snow  chains are suitably  covered.  Check 
the  position  of  the  snow  chains after 
driving  a few  yards  and correct  if neces
sary. Follow  the  instructions from  the 
snow  chain  manufacturer  when  doing so. 
-If the  Adaptive  Air  Suspension* should 
malfunction,  do  not  mount  or  use snow

chains  because  the  vehicle  will  be  ex
tremely  low.  If  you  do  drive  with  snow 
chains  on  while  the  vehicle  is at  this  lev
el,  the  snow  chains  might  severe ly dam
age  the  wheelhouse  and  other  parts  of 
the  veh icle . 
@ Tips 
Where  snow  cha ins  are  mandatory  oncer
tain  roads,  this  normally  also  applies  to 
veh icles  with  all -wheel  dr ive. 
Wheel  bolts 
Wheel  bolts  mu st always  be  tigh tened  to  the 
correc t  torque . 
The  design  of whee l bolts  is  matched  to  the 
factory  in sta lled  r ims.  If  different  rims  are  fit 
ted,  the  correct  wheel  bolts  with  the  right 
length  and  correctly  shaped  bolt  heads  must 
be  used . This  ensures  that  wheels  are  f itted 
secure ly and  that  the  brake  system  f unctions 
correctly . 
In  certain  circumstances,  you  may  not  use 
wheel  bolts  from  a d iffe rent  vehicle  -even  if  it 
i s the  same  mode l 
¢page  285. 
A WARNING 
Imprope rly tig hte ned  or  maintained  whee l 
bolts  can  be come  loose  causin g loss  of 
contro l,  a  co llision  and  serious  persona l in
jury . 
- Alw ays  keep  the  w heel  bolts  and  the 
th reads  in the  wheel  hubs  clea n so  the 
wheel  bolts  can  turn  easily  and  be  prop
er ly tightened . 
- Never  grease  or  oil the  wheel  bo lts and 
the  threads  in the  w heel  h ubs. They  can 
become  loose  while  driving  if greased  or 
o iled,  even  if tightened  to  the  specif ied 
torque. 
- Only use  wheel  bolts  that  belong  to  the  rim  being  installed. 
- Never  use  different  whee ls  bolts  on your 
vehicle . 
- Always  maintain  the  co rrect  tightening 
torq ue  for  the  wheel  bo lts  to  reduce  the 
Tire s an d wheel s 257 
risk of a wheel  loss.  If  the  tighte ning  tor
que  of t he wheel  bolts  is  too  low, they 
can  loosen  and  come  out  when  the  vehi
cle  is  mov ing . If  the  tighte ning  torque  is 
too  h igh,  the  wheel  bol ts  and  threads 
can  be  damaged  and  the  whee l can  be

Low aspect  ratio  tires 
Your Audi is facto ry-eq uipped  with  low  aspect 
ratio  tires.  These  tires  have  been  thoro ughly 
tested  and  been  se lected  specifically  for  your 
model  for  their  superb  performance , road  fee l 
and  handling  under  a variety  of driving  cond i
tions . Ask your  authorized  Audi dealer  for 
more  details. 
The  low  aspect  ratio  of  these  t ires  is  ind icated 
by a  numeral  of 
55  or less in the  tire's  size 
designation . The  numera l rep resents  the  ratio 
of  the  t ire's  sidewall  height  in relation  to  its 
t read  width  ex pressed  in  perce ntage.  Conven 
tion al  tires  have  a he igh t/w idth  ratio  of  60  or 
more. 
The performance  of  low-aspe ct-ratio  tire s is 
particularly  sensitiv e to  improper  infla tion 
pres sure.  It  is therefore  important  that  l ow 
a spect ratio  tires  are inflated  to the  specified 
pre ssure and that  the  inflation  pressure is 
regularly  checked and  maintained.  Tire pres· 
sures should  be checked at  least  once a 
month  and  always  before  a long trip 
¢ page  246,  Checking tire  pressure . 
What  you  can  do to  avoid  tire  and  rim 
damage 
Low aspect  ratio  tires  can  be  damaged  more 
easily  by impact  w it h  potholes , curbs,  gul lies  ..,.

or  ridges  on  the  road,  particularly if the  tire is 
underinflated. 
I n  o rder  to minim ize the  occurrence  of impact 
damage  to  the  tires  of  your  vehicle,  we  recom
mend  that  you  observe  the  following  precau 
tions: 
- Always  maintain  recommended  inflation 
pressures.  Check 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  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 ir e as  soon  as  possible . 
- Inspect  your  tires  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 ir e  may  have  been  damaged,  replace the 
tire  as  soon  as  possible. 
- T hese  tires  may  wea r mo re  quick ly  than  oth
ers. 
- Please  a lso  remember  that,  while  these  t ires 
deliver  respons ive  handling,  they  may  ride 
less  comfortably  and  make  more  no ise  than 
other  choices. 
Reduced performance  in winter/cold 
season  conditions 
All  tires  are  designed  for  certain  purposes. 
The  low  aspect  ratio,  ultra high  performance 
tires  originally  installed  on your  vehicle  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  drive  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 
for  your  vehicle,  or  their equivalent.  Refer 
to 
q page 255 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,  including the spare  ( if provided), 
shou ld be  checked  monthly  when  co ld and  in
flated  to  the  inflation  pressure  recommended 
by the  veh icle  manufacturer  on  the  vehicle 
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
flation  pressure  label, you  should  determine 
the  proper  tire  inflation  p ressu re 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) that  illuminates  a  low tire 
pressure  telltale when one or more  of  your 
tires  is significant ly under-inflated.  According
l y, when  the  low  tire  pressure  telltale  i llumi
nates,  you  should  stop  and  check  your  tires  as 
soon  as  possible,  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 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  ma intenance,  and  it is the  driv
er's  responsibility  to maintain  correct  tire 
pressure,  even  if under-inflation  has  not 
reached  the  level  to  trigger  illuminat ion of  the 
TPMS  low  tire  pressu re tellta le . 
Your vehicle  has  also  been  equipped  with  a 
TPM S malfunction  indicator to ind icat e when 
the  system  is  not operating  properly.  The 
T PMS ma lfunction  indicator  is combined  with 
the  low  tire  pressure  telltale. When the  sys
tem  detects  a  malfunction,  the  telltale  will 
flash  for  approximately  one minute  and  then  ..,_
