Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
possible  and  inflate  the  tires  with  low  pres -
sure (those in a different color in the instru -
ment  cluster  graphic)  to  the  vehicle’s
recommended  cold  placard  pressure  value.
Once  the  system  receives  the  updated  tire
pressures,  the  system  will  automatically
update,  the  pressure  values  in  the  graphic
display  in  the  instrument  cluster  will  return
to their original color, and the TPMS Warning
Light will turn off.  NOTE:
When  filling  warm  tires,  the  tire  pressure
may need to be increased up to an additional
4 psi (28 kPa) above the recommended cold
placard  pressure  in  order  to  turn  the  TPMS
Warning Light off.
The  vehicle  may  need  to  be  driven  for  up  to
10 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
Service TPMS Warning
When  a  system  fault  is  detected,  the  TPMS
Warning  Light  will  flash  on  and  off  for  75
seconds  and  then  remain  on  solid.  The
system fault will also sound a chime. In addi
-
tion,  the  instrument  cluster  will  display  a
"SERVICE  TIRE  PRESSURE  SYSTEM"
message for a minimum of five seconds and
then display dashes (--) in place of the pres -
sure  value  to  indicate  which  sensor  is  not
being received. If  the  ignition  is  cycled,  this  sequence  will
repeat, providing the system fault still exists.
If  the  system  fault  no  longer  exists,  the
TPMS Warning Light will no longer flash, and
the  “SERVICE  TIRE  PRESSURE  SYSTEM”
message  will  no  longer  display,  and  a  pres
-
sure value will display in place of the dashes.
A  system  fault  can  occur  due  to  any  of  the
following:
Jamming  due  to  electronic  devices  or
driving next to facilities emitting the same
radio frequencies as the TPMS sensors
Installing  some  form  of  aftermarket
window  tinting  that  affects  radio  wave
signals
Lots  of  snow  or  ice  around  the  wheels  or
wheel housings
Using tire chains on the vehicle
Using  wheels/tires  not  equipped  with
TPMS sensors

permitted  with  the  use  of  245/75R17
tires on size 17 x 7.5 ET44.45 wheels.
 CAUTION!
If  your  vehicle  is  equipped  with  these
specialty  wheels,  DO  NOT  USE  wheel
cleaners,  abrasives,  or  polishing
compounds.  They  will  permanently
damage this finish and such damage is not
covered  by  the  New  Vehicle  Limited
Warranty.  HAND  WASH  ONLY  USING
MILD  SOAP  AND  WATER  WITH  A  SOFT
CLOTH. Used on a regular basis; this is all
that is required to maintain this finish.
 WARNING!
Using  tires  of  different  size  and  type
(M+S,  Snow)  between  front  and  rear  axles
can  cause  unpredictable  handling.  You
could lose control and have a collision.
 CAUTION!
To  avoid  damage  to  your  vehicle  or  tires,
observe the following precautions:
Because  of  restricted  traction  device
clearance  between  tires  and  other
suspension  components,  it  is  important
that only traction devices in good condi -
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately  if  noise  occurs  that  could  indi -
cate  device  breakage.  Remove  the
damaged  parts  of  the  device  before
further use.
Install  device  as  tightly  as  possible  and
then retighten after driving about ½ mile
(0.8 km).  Autosock  traction  devices  do
not require retightening.
Do not exceed 30 mph (48 km/h).
Drive  cautiously  and  avoid  severe  turns
and  large  bumps,  especially  with  a
loaded vehicle.
Do  not  drive  for  a  prolonged  period  on
dry pavement.
