Low Fuel Warning LightWhen the fuel level reaches approximately 2–3 gal
(9–11 L) this light will turn on, and remain on until
fuel is added.
Generic Warning Light The Generic Warning Light will illuminate if any of
the following conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure, Parking
Sensor Failure, Fuel Cut-Off Fail/Intervention, Generic
Failure on Trailer, or Air Bag telltale recovery.
The telltale will blink in case of an Air Bag Warning Light
Failure. Contact an authorized dealer immediately for
service.
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is lower
than the recommended value and/or that slow pres -
sure loss is occurring. In these cases, optimal tire duration
and fuel consumption may not be guaranteed. Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi
-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure.
Under-inflation also 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
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS malfunc -
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi -
cator is illuminated, the system may not be able to detect or
signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation
of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace
-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.
Vehicle Security Warning Light
This warning light will illuminate when the vehicle
security alarm system has detected an attempt to
break into the vehicle. 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.
Aftermarket wheels can cause sensor damage. 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.

SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel Anti-Lock Brake System (ABS) is designed
to aid the driver in maintaining vehicle control under
adverse braking conditions. The system operates with a
separate computer to modulate hydraulic pressure, to
prevent wheel lock-up and to help avoid skidding on
slippery surfaces.
The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When the
light is illuminated, the ABS is not functioning. The system
reverts to standard non-anti-lock brakes. Turning the igni-
tion OFF and ON again may reset the ABS if the fault
detected was only momentary.
WARNING!
• The ABS contains sophisticated electronic equipment that may be susceptible to interference caused by
improperly installed or high output radio transmitting
equipment. This interference can cause possible loss of
anti-lock braking capability. Installation of such equip -
ment should be performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
• The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking
or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the traction
afforded.

ESC Activation/Malfunction Indicator Light And ESC
OFF Indicator Light The ESC Activation/Malfunction Indicator Light in
the instrument cluster will come on when the igni -
tion switch is turned to the MAR (ON/RUN) posi -
tion for four seconds. If the ESC Activation/Malfunction
Indicator Light comes on continuously with the engine
running, a malfunction has been detected in the ESC system.
If this light remains on after several ignition cycles, and the vehicle has been driven several miles (km) at speeds greater
than 30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located in
the instrument cluster) starts to flash as soon as the tires lose
traction and the ESC system becomes active. The ESC Activa
-
tion/Malfunction Indicator Light also flashes when TCS is
active. If the ESC Activation/Malfunction Indicator Light
begins to flash during acceleration, ease up on the accelerator
and apply as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
NOTE:
• The ESC Activation/Malfunction Indicator Light and the ESC OFF Indicator Light come on momentarily each time
the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system will be ON even if it was turned off previously.
The ESC OFF Indicator Light indicates the Electronic
Stability Control (ESC) is partially off.
• Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteristics
of your vehicle, and may negatively affect the perfor -
mance of the ESC system. Changes to the steering
system, suspension, braking system, tire type and size
or wheel size may adversely affect ESC performance.
Improperly inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle modification or
poor vehicle maintenance that reduces the effective -
ness of the ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal injury and
death.

SAFETY 103
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a three hour period.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires” in “Servicing And Maintenance” for infor -
mation on how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven - this is
normal and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire. The TPMS will continue to warn the driver of low tire pres
-
sure as long as the condition exists, and will not turn off until
the tire pressure is at or above the recommended cold
placard pressure. Once the low tire pressure warning (TPMS
Warning Light) illuminates, you must increase the tire pres -
sure to the recommended cold placard pressure in order for
the TPMS Warning Light to turn off. The system will auto -
matically update and the TPMS Warning Light will turn off
once the system receives the updated tire pressures. 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 infor -
mation.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom -
mended cold placard pressure in order to turn the TPMS
Warning Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30 psi
(207 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to approx -
imately 23 psi (158 kPa). This tire pressure is sufficiently low
enough to turn on the TPMS Warning Light. Driving the
vehicle may cause the tire pressure to rise to approximately

27 psi (186 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle’s recommended cold
placard pressure value.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 under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency 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 accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
CAUTION!
• The TPMS has been optimized for the original equip -
ment 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. After -
market wheels can cause sensor damage.
• Using aftermarket tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho -
rized dealership 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.

SAFETY 105
Base SystemThis is the TPMS warning indicator located in the
instrument cluster.
The 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 regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring sensors
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning Light will
illuminate in the instrument cluster, an audible chime will be
activated, and the “Check tire pressure” text message will
display when one or more of the four active road tire pres -
sures are low. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s recommended
cold placard pressure value. The system will automatically
update and the Tire Pressure Monitoring Light will extin
-
guish once the updated tire pressures have been received.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Warning Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, an audible chime will be activated and a
proper text message will be displayed. If the ignition key is
cycled, this sequence will repeat providing the system fault
still exists. The Tire Pressure Monitoring Warning Light will
turn off when the fault condition no longer exists. A system
fault can occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next to facil -
ities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
