Yellow Warning Lights
— Anti-Lock Brake (ABS) Warning Light
This warning light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition is placed in
the ON/RUN or ACC/ON/RUN position and may stay on
for as long as four seconds.
If the ABS light remains on or turns on while driving, then
the Anti-Lock portion of the brake system is not function-
ing and service is required as soon as possible. However,
the conventional brake system will continue to operate
normally, assuming the Brake Warning Light is not also on.
If the ABS light does not turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position, have
the brake system inspected by an authorized dealer.
— Electronic Stability Control (ESC) Warning
Light — If Equipped
The “ESC Indicator Light” in the instrument cluster will
come on when the ignition is placed in the ON/RUN or
MAR (ACC/ON/RUN) position, and when ESC is acti-
vated. It should turn off with the engine running. If the
“ESC 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
(kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
• The “ESC Off Indicator Light” and the “ESC Indicator
Light” come on momentarily each time the ignition is
placed in the ON/RUN or MAR (ACC/ON/RUN)
position.
• Each time the ignition is turned to ON/RUN or MAR
(ACC/ON/RUN), the ESC system will be on, even if it
was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive.
• This light will come on when the vehicle is in an ESC
event.
— Electronic Stability Control (ESC) Off Warning
Light — If Equipped
This light indicates the Electronic Stability Control (ESC) is
off.88 GETTING TO KNOW YOUR INSTRUMENT PANEL

Each time the ignition is turned to ON/RUN or ACC/ON/
RUN, the ESC system will be on, even if it was turned off
previously.

— Low Fuel Warning Light
When the fuel level reaches approximately 1–1.3 gal (3–5 L)
this light will turn on, and remain on until fuel is added.
— Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that 4GETTING TO KNOW YOUR INSTRUMENT PANEL 89

monitors engine and automatic transmission control sys-
tems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the ve-
hicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others. CAUTION!Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
— ParkSense Failure Warning Light
This warning light will illuminate when the ParkSense
System is not functioning properly and service is required.
Contact an authorized dealer.
— Service Warning Light — If Equipped
The “Maintenance Plan” includes vehicle maintenance at
fixed intervals. For further information, refer to  Scheduled
Servicing” in “Servicing And Maintenance”. This message
is displayed automatically along with the warning light
when the key is turned to MAR (ACC/ON/RUN) - 1,242
miles (2,000 km) before these deadlines and reappears
every 124 miles (200 km). Below 124 miles (200 km)
servicing indications are more frequent. The indication will
appear in miles or kilometers according to the  Unit Of
Measurement  settings. When the next scheduled service is90 GETTING TO KNOW YOUR INSTRUMENT PANEL

approaching and the key is turned to MAR (ACC/ON/
RUN), the word “Service” will appear on the display,
followed by the number of miles or kilometers left. Contact
a dedicated authorized dealership. The operations in the
“Maintenance Plan” will be performed and the message
will be reset.
— 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 recom-
mended value and/or that slow pressure 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.
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 (Continued) CAUTION! (Continued)occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.
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 illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly 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. 4GETTING TO KNOW YOUR INSTRUMENT PANEL 91

Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure 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
indicator 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 replacement or alternate tires and wheels
allow the TPMS to continue to function properly. 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 equip-
ment 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 inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your au-
thorized dealer to have your sensor function checked.
— Immobilizer Vehicle Theft Alarm Warning Light
This warning light will illuminate when the vehicle secu-
rity alarm system has detected an attempt to break into the
vehicle.
— Fuel Level Sensor Failure
This light illuminates when there is a fuel level sensor
failure. If this light illuminates, take it to an authorized
dealer and have them inspect it.92 GETTING TO KNOW YOUR INSTRUMENT PANEL

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.
CAUTION!• Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed. (Continued) CAUTION! (Continued)• If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!• ONLY an authorized service technician should connect
equipment to the OBD II connection port in order to
read the VIN, diagnose, or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of (Continued) 4GETTING TO KNOW YOUR INSTRUMENT PANEL 95

WARNING! (Continued)vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in the
“Multimedia” section.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Main-
tenance (I/M), this check verifies the “Malfunc-
tion Indicator Light (MIL)” is functioning and is
not on when the engine is running, and that the
OBD II system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the follow-
ing:
1. Cycle the ignition switch to the ON position, but do not
crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON
position, you will see the “Malfunction Indicator Light
(MIL)” symbol come on as part of a normal bulb check.96 GETTING TO KNOW YOUR INSTRUMENT PANEL

SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking condi-
tions. 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 equip-
ment that may be susceptible to interference caused (Continued) WARNING! (Continued)by improperly installed or high output radio trans-
mitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation
of such equipment 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 brak-
ing or steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires or the
traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.100 SAFETY

A feature of the TCS system, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if TCS
and ESC are in the Partial Off mode. Refer to “Electronic
Stability Control (ESC)” in this section for further informa-
tion.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes his foot off the brake
pedal. If the driver does not apply the throttle during this
short period of time, the system will release brake pressure
and the vehicle will roll down the hill. The system will
release brake pressure in proportion to the amount of
throttle applied as the vehicle starts to move in the
intended direction of travel. HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• Vehicle must be stopped.
• Vehicle must be on a 2.5% (manual transmission) or 7%
grade or greater (automatic transmission) hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle
facing uphill is in forward gear; vehicle backing uphill is
in REVERSE gear).
WARNING!There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system will
not activate and slight rolling may occur. This could
cause a collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.102 SAFETY

ESC Operating Modes
The ESC system has two available operating modes.
Full On
This is the normal operating mode for ESC. Whenever the
vehicle is started, the ESC system will be in On mode. This
mode should be used for most driving situations. ESC
should only be turned to Partial Off for specific reasons as
noted below.
Partial Off
This mode is entered by momentarily pushing the ESC Off
switch. This mode is intended to be used if the vehicle is in
deep snow, sand or gravel conditions and more wheel spin
than ESC would normally allow is required to gain trac-
tion.
To turn ESC on again, momentarily pushing the switch
again. This will restore the normal ESC On mode of
operation.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the Partial Off mode by pushing the switch. Once the situation requiring ESC to
be switched to the Partial Off mode is overcome, turn ESC
back on by momentarily pushing the switch. This may be
done while the vehicle is in motion.
WARNING!When in “Partial Off” mode, the TCS functionality of
ESC (except for the limited slip feature described in
the TCS section) has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction of TCS is
disabled, and the enhanced vehicle stability offered by
the ESC system is reduced.
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
ignition switch is turned to the MAR (ACC/ON/
RUN) position for four seconds. If the ESC
Activation/Malfunction Indicator Light comes on continu-
ously with the engine running, a malfunction has been
detected in the ESC system. If this light remains on after 5 SAFETY 105
