Low Tire Pressure Warning Lamp
It illuminates when your tire
pressure is low. If the lamp remains
on with the engine running or
when driving, check your tire pressure as
soon as possible.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp is
functional. If it does not illuminate when you
switch the ignition on, or begins to flash at
any time, have the system checked by your
authorized dealer.
Low Beam Malfunction Warning Lamp It illuminates when there is a
malfunction with the low beam
headlamp bulb.
Low Washer Fluid Level Warning Lamp It illuminates when the washer fluid
is low. Parking Lamps Illuminates when you switch the
parking lamps on.
Powertrain Fault Illuminates when a powertrain or
an 4WD fault has been detected.
Contact an authorized dealer.
Service Engine Soon If it illuminates when the engine is
running this indicates a
malfunction. The On Board
Diagnostics system has detected a
malfunction of the vehicle emission control
system.
If it flashes, engine misfire may be occurring.
Increased exhaust gas temperatures could
damage the catalytic converter or other
vehicle components. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
immediately serviced. It illuminates when you switch the ignition
on prior to engine start to check the bulb and
to indicate whether your vehicle is ready for
Inspection and Maintenance (I/M) testing.
Normally, it illuminates until the engine is
cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.
See Catalytic Converter (page 224).
Stability Control and Traction Control
Indicator Flashes during operation.
If it does not illuminate when you
switch the ignition on, or remains
on when the engine is running, this indicates
a malfunction. Have your vehicle checked
as soon as possible.
See
Using Stability Control (page 249).

•
An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.
Note: Some vehicles have a lifetime fuel filter
that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.
Note: If these checks do not help you correct
the concern, have your vehicle checked as
soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 346).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
