Engine Check/Malfunction Indicator
Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard
D ia
gn
os
tic System called OBD II that
monitors engine and automatic
transmission control systems. 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.
The vehicle should be serviced if the light stays on
throug h

several 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 serviced
as soon as possible if this occurs.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal
a fault with the 4WD system. If the light
stays
on or comes on during driving, it
means that the 4WD system is not
functioning properly and that service is required.
We recommend you drive to the nearest service
center and have the vehicle serviced immediately.
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.

ESC system is Active. The ESC Indicator
Light
in the instrument cluster will come
on when the ignition is placed in the ON/
RUN or ACC/ON/RUN position, and when ESC is
activated. It should go out 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 warning light
remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers)
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 sys -
tem operation or sensor damage may result
w hen u

sing replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to
b ecome

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.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.

ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an 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 access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú page 133.
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
Maintenance (I/M), this check verifies
the Ma

lfunction 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 n
ot be r
eady if your vehicle was
recently serviced, recently had a depleted battery
or a battery replacement. If the OBD II system
should be determined not ready for the I/M test,
your vehicle may fail the test.
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.
If the MIL is flashing, while the engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
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 vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
inclu d
ing personal information.

GETTING TO KNOW YOUR INSTRUMENT PANEL 79
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 following:

1. Cycle the ignition switch to the ON position,
but d
o 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 pos
ition, you will see the Malfunction
Indicator Light (MIL) symbol come on as part of
a normal bulb check. 3. Approximately 15 seconds later, one of two
thing

s will happen:
The MIL will flash for about 10 seconds and
then return to being fully illuminated until
you turn OFF the ignition or start the engine.
This means that your vehicle's OBD II
system is not ready and you should not
proceed to the I/M station.
The MIL will not flash at all and will remain
fully illuminated until you place the ignition
in the off position or start the engine. This
means that your vehicle's OBD II system is
ready and you can proceed to the I/M
station. If your OBD II system is
not rea
dy, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do nothing
more than drive your vehicle as you normally would
in order for your OBD II system to update. A
recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
is re a

dy or not, if the MIL is illuminated during
normal vehicle operation you should have your
vehicle serviced before going to the I/M station.
The I/M station can fail your vehicle because the
MIL is on with the engine running.3

GEAR RANGES
PARK (P)
This range supplements the Electric Park Brake
(
E P
B )


by locking the transmission. The engine can
be started in this range. Never attempt to use
PARK while the vehicle is in motion.
When parking on a hill, apply the EPB before
shifti
ng the transmission to PARK, otherwise the
load on the transmission locking mechanism may
make it difficult to move the gear selector out of
PARK. As an added precaution, turn the front
wheels toward the curb on a downhill grade and
away from the curb on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition OFF.
Remove the key fob from the vehicle.
CAUTION!
After selecting any gear range, wait a moment to
allow the selected gear to engage before
accelerating. This is especially important when
the engine is cold.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
b linki

ng. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally (or stopped) and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running or the propulsion system
is active. Before exiting a vehicle, always come
to a complete stop, then apply the parking
brake, shift the transmission into PARK, and
turn the ignition OFF. When the ignition is in
the OFF position, the transmission is locked in
PARK, securing the vehicle against unwanted
movement.
When leaving the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.
WARNING!

Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle
Ú page 329.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer Ú page 329.
For the proper tire replacement procedures
Ú page 329. Replacing tires with a higher load
carrying capacity will not increase the vehicle's
G VWR a

nd GAWR limits.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance,
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure,
or tire
s.
Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the frame or hook retainers of the
vehicle hitch. Cross the chains under the
trailer tongue and allow enough slack for
turning corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. Always block or "chock"
the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded:
GVWR
GTW
WARNING!
GAWR
Tongue weight rating for the trailer hitch
utilized.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The e n
gine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a trai
ler is towed, do not drive over 50 mph
( 8
0 k
m /
h) and do not make starts at full
thrott l
e. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have a collision.
