SERVICE TIRE MONITOR SYSTEM
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays if a part on the TPMS
is not working properly. The tire pressure light also
ashes and then remains on during the same ignition
cycle. SeeTire Pressure Light on page 3-39. Several
conditions may cause this message to appear. See
Tire Pressure Monitor Operation on page 6-65for more
information. If the warning comes on and stays on,
there may be a problem with the TPMS. See your
dealer/retailer.
SERVICE TRACTION CONTROL
If your vehicle has StabiliTrak®, this message displays
when there is a problem with the Traction Control
System (TCS). When this message displays, the system
will not limit wheel spin. Adjust your driving accordingly.
See your dealer/retailer for service. SeeStabiliTrak
®
System on page 5-6for more information.
SIDE BLIND ZONE ALERT
SYSTEM OFF
If your vehicle has the Side Blind Zone Alert (SBZA)
system, this message displays when the SBZA system
has been turned off. SeeSide Blind Zone Alert
(SBZA) on page 2-44andDIC Operation and Displays
on page 3-46for more information.
SIDE BLIND ZONE SYSTEM
UNAVAILABLE
If your vehicle has the Side Blind Zone Alert (SBZA)
system, this message displays when the SBZA system
is disabled because the sensor is blocked and cannot
detect vehicles in your blind zone. The sensor may
be blocked by mud, dirt, snow, ice, or slush. This
message may also display during heavy rain or due to
road spray. It may also come on when driving in
isolated areas with no guardrails, trees, or road signs
and light traffic. Your vehicle does not need service.
For cleaning instructions, seeWashing Your Vehicle
on page 6-98. SeeSide Blind Zone Alert (SBZA)
on page 2-44for more information.
STABILITRAK®OFF
If your vehicle has StabiliTrak®, this message displays
when you turn off StabiliTrak®, or when the stability
control has been automatically disabled. To limit wheel
spin and realize the full benets of the stability
enhancement system, you should normally leave
StabiliTrak
®on. However, you should turn StabiliTrak®off
if your vehicle gets stuck in sand, mud, ice, or snow and
you want to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and require
more wheel spin. SeeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 5-30. To turn the StabiliTrak
®
system on or off, seeStabiliTrak®System on page 5-6.

There are several conditions that can cause this
message to appear.
One condition is overheating, which could occur if
StabiliTrak®activates continuously for an extended
period of time.
The message also displays if the brake system
warning light is on. SeeBrake System Warning
Light on page 3-37.
The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer/retailer.
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
TIGHTEN GAS CAP
This message may display along with the check engine
light on the instrument panel cluster if the vehicle’s
fuel cap is not tightened properly. SeeMalfunction
Indicator Lamp on page 3-40. Reinstall the fuel cap fully.SeeFilling the Tank on page 6-9. The diagnostic
system can determine if the fuel cap has been left off
or improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn this light and message off.
TIRE LEARNING ACTIVE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the TPMS
is re-learning the tire positions on your vehicle. The tire
positions must be re-learned after rotating the tires
or after replacing a tire or sensor. SeeTire Inspection
and Rotation on page 6-68,Tire Pressure Monitor
System on page 6-63, andInflation - Tire Pressure on
page 6-61for more information.

High-Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h) or
higher, puts an additional strain on tires. Sustained
high-speed driving causes excessive heat build up
and can cause sudden tire failure. You could have
a crash and you or others could be killed. Some
high-speed rated tires require ination pressure
adjustment for high speed operation. When speed
limits and road conditions are such that a vehicle
can be driven at high speeds, make sure the tires
are rated for high speed operation, in excellent
condition, and set to the correct cold tire ination
pressure for the vehicle load.
If your vehicle has P265/65R18 or P285/45R22
size tires and you will be driving at high speeds, speeds
of 100 mph (160 km/h) or higher, set the cold ination
pressure to 3 psi (20 kPa) above the recommended tire
pressure shown on the Tire and Loading Information
Label. When you end this high-speed driving, return the
tires to the cold ination pressure shown on the Tire and
Loading Information label. SeeLoading the Vehicle on
page 5-32andInflation - Tire Pressure on page 6-61.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated tire
causes the tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.

Tire Pressure Monitor Operation
If your vehicle is a Two-mode Hybrid, see the
Two-mode Hybrid manual for more information.
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver
when a low tire pressure condition exists. TPMS sensors
are mounted onto each tire and wheel assembly,
excluding the spare tire and wheel assembly. The TPMS
sensors monitor the air pressure in the vehicle’s tires
and transmit the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light located on the
instrument panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and the
DIC warning message come on at each ignition cycle
until the tires are inated to the correct ination pressure.Using the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 3-46andDIC Warnings and Messages
on page 3-54.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct ination pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 5-32, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also seeInflation - Tire Pressure on page 6-61.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation on
page 6-68andTires on page 6-56.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not covered
by your warranty. Do not use liquid tire sealants.

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for
the remainder of the ignition cycle. A DIC warning
message is also displayed. The low tire warning light
and DIC warning message come on at each ignition
cycle until the problem is corrected. Some of the
conditions that can cause the malfunction light and
DIC message to come on are:
One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the road
tire containing the TPMS sensor.
The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle’s tires. The DIC message
and TPMS malfunction light should go off once
the TPMS sensor matching process is performed
successfully. See “TPMS Sensor Matching Process”
later in this section.
One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels.
Tires and wheels other than those recommended
for your vehicle could prevent the TPMS from
functioning properly. SeeBuying New Tires on
page 6-70.
Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer/retailer for
service if the TPMS malfunction light and DIC message
comes on and stays on.
