Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake
application. If the brake light turns on it may indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with the anti-lock brake system reser-
voir.
If the light remains on when the parking brake has been disengaged, and the fluid level is
at the full mark on the master cylinder reservoir, it indicates a possible brake hydraulic sys-
tem malfunction or that a problem with the Brake Booster has been detected by the Anti-
Lock Brake System (ABS) / Electronic Stability Control (ESC) system. In this case, the light
will remain on until the condition has been corrected. If the problem is related to the Brake
Booster, the ABS pump will run when applying the brake, and a brake pedal pulsation may
be felt during each stop.
NOTE:
Brake Warning Light may illuminate due to excessive wear to brake pads.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual brake
system is indicated by the Brake Warning Light, which
will turn on when the brake fluid level in the master
cylinder has dropped below a specified level. The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.4

Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine and automatic transmission control systems. The
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 key 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 sev-
eral typical driving styles. In most situations, the vehicle 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 ser-
viced as soon as possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in nor-
mal operating conditions. This can cause a fire if

you drive slowly or park over flammable sub-
stances 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 engine
control system. It also could affect fuel economy

CAUTION!(Continued)
and driveability. If the MIL is flashing, severe
catalytic converter damage and power loss will soon
occur. Immediate service is required.
Tire Pressure Monitoring Indicator Light
Yellow Telltale
Light What It Means
Tire Pressure Monitoring Indicator 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 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 in sequence.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair imme-
diately using the dedicated tire repair kit and con-
tact your authorized dealership 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 pres-
sure label, you should determine the proper tire infla-
tion pressure for those tires.

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread
depth becomes a 1/16 of an inch (1.6 mm). When the
tread is worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement Tires” in this
section for further information.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style.
• Tire pressure - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle
maintenance schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire fail-
ure. You could lose control and have a collision
resulting in serious injury or death.

STARTING AND OPERATING 257

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 transmis-
sion control systems. When these systems are operating
properly, your vehicle will provide excellent perfor-
mance 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 your 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 emis-
sions tests can be performed.
• If the MIL is flashing while the engine 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 emis-
sions controls. Authorized service technicians may need
to access this information to assist with the diagnosis
and service of your vehicle and emissions system.
300 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate in the instrument
cluster. This means that service is required for your
vehicle. Operating conditions such as frequent short-
trips, trailer tow and extremely hot or cold ambient
temperatures will influence when the “Change Oil” or
“Oil Change Required” message is displayed. Severe
Operating Conditions can cause the change oil message
to illuminate as early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indica-
tor message after completing the scheduled oil change.
If a scheduled oil change is performed by someone
other than your authorized dealer, the message can be
reset by referring to the steps described under “Instru-
ment Cluster Display” in “Understanding Your Instru-
ment Panel” for further information.NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment
or is operated predominately at idle or only very low
engine RPM’s. This type of vehicle use is considered
Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for un-
usual wear or damage.
• Check the fluid levels of the coolant reservoir, and
brake master cylinder reservoir, and fill as needed.
• Check function of all interior and exterior lights.
