be on. In this situation, the Tire Pressure
Monitoring System Warning Light will turn off only
after the tires are inflated to the vehicle’s
recommended cold placard pressure value
Ú
page 328.
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 Tire Pressure Monitoring System
Warning Light off.
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the Tire Pressure Monitoring System Warning
Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Premium System
The Tire Pressure Monitoring System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System
messages, which will display in the instrument
cluster display
Tire Pressure Monitoring System Warning Light
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
CAUTION!

Tire Pressure Monitoring System Low
Pressure Warnings

The Tire Pressure Monitoring System
Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of
the four active road tires. In addition, the instrument
cluster will display a "Tire Low" message, an “Inflate
to XX” message, and a graphic showing the
pressure values of each tire with the low tire
pressure values highlighted or in a different color.

Tire Pressure Monitoring System Low Pressure Warning

Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those highlighted or in a different color in the
instrument cluster display graphic) to the vehicle’s
recommended cold placard pressure value, as
shown in the “Inflate to XX” message. 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 stop being highlighted or return to their
original color, and the Tire Pressure Monitoring
System 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 Tire Pressure Monitoring System
Warning Light off.
The vehicle may need to be driven for up to
20 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 Tire Pressure
Monitoring System Warning Light will flash on and
off for 75 seconds and then remain on solid. The
system fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five seconds
and then display dashes (--) in place of the pressure
value to indicate which sensor is not being received.

If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. If the
system fault no longer exists, the Tire Pressure
Monitoring System Warning Light will no longer
flash, and the “SERVICE TPM SYSTEM” message
will no longer display, and a pressure 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
Vehicles With Compact Spare Or Non-Matching
Full Size Spare

1. The compact spare tire or non-matching full size does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact or
non-matching full size spare tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key cycle, the Tire
Pressure Monitoring System Warning Light will
remain on and a chime will sound. In addition,
the graphic in the instrument cluster will still
display a different color or highlighted pressure
value and the “Inflate to XX” message.

3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the Tire Pressure
Monitoring System Warning Light will flash on
and off for 75 seconds and then remain on
solid. In addition, the instrument cluster will
display a “SERVICE TPM SYSTEM” message for
five seconds and then display dashes (--) in
place of the pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the Tire Pressure Monitoring
System Warning Light will flash on and off for
75 seconds and then remain on solid, and the
instrument cluster will display a “SERVICE TPM
SYSTEM” message for five seconds and then
display dashes (--) in place of the pressure
value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the
compact spare or non-matching full size, the
TPMS will update automatically. In addition,
the Tire Pressure Monitoring System Warning
Light will turn off and the graphic in the
instrument cluster will display a new pressure
value instead of dashes (--), as long as no tire
pressure is below the low-pressure warning
limit in any of the four active road tires.
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four
wheel and tire assemblies (road tires) with wheel
and tire assemblies that do not have TPMS
sensors, such as when installing winter wheel and
tire assemblies on your vehicle.
To deactivate the TPMS, first replace all four wheel
and tire assemblies (road tires) with tires not
equipped with Tire Pressure Monitoring System
(TPMS) sensors. Then, drive the vehicle for
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds
and then remain on. The instrument cluster will
display the “SERVICE TPM SYSTEM” message and
then display dashes (--) in place of the pressure
values.
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE TPM
SYSTEM” message in the instrument cluster but
dashes (--) will remain in place of the pressure
values.
To reactivate the TPMS, replace all four wheel and
tire assemblies (road tires) with tires equipped with
TPMS sensors. Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and then turn off. The instrument cluster will
display the “SERVICE TPM SYSTEM” message and
then display pressure values in place of the
dashes. On the next ignition cycle the "SERVICE
TPM SYSTEM" message will no longer be displayed
as long as no system fault exists.

NOTE:
P (Passenger) — Metric tire sizing is based on US
design standards. P-Metric tires have the letter
“P” molded into the sidewall preceding the size
designation. Example: P215/65R15 95H.
European — Metric tire sizing is based on
European design standards. Tires designed to
this standard have the tire size molded into the
sidewall beginning with the section width. The
letter "P" is absent from this tire size designa -
tion. Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based on
US design standards. The size designation for
LT-Metric tires is the same as for P-Metric tires
except for the letters “LT” that are molded into
the sidewall preceding the size designation.
Example: LT235/85R16.
Temporary spare tires are designed for tempo -
rary emergency use only. Temporary high pres -
sure compact spare tires have the letter “T” or
“S” molded into the sidewall preceding the size
designation. Example: T145/80D18 103M.
High flotation tire sizing is based on US design
standards and it begins with the tire diameter
molded into the sidewall.
Example: 31x10.5 R15 LT.
WARNING!
Modifications or repair of the electrical system
performed incorrectly and without taking into
account the technical characteristics can
cause malfunctions with the risk of fire.
Halogen lamps contain gas under pressure, in
the event of breakage be careful of the projec -
tion of fragments of glass.
Halogen lamps must be handled by touching
only the metallic part. If the transparent bulb
is in contact with the fingers, reduces the
