Powertrain Malfunction/Reduced
Power/Electronic Throttle Control

Illuminates when a powertrain
or an 4WD fault has been
detected. Contact your

authorized dealer as soon as possible.

Service Engine Soon

If the service engine soon
indicator light stays illuminated
after the engine is started, it

indicates that the On-Board Diagnostics
(OBD-II) system has detected a
malfunction of the vehicle emissions
control system. Refer to On-Board
Diagnostics (OBD-II) in the Fuel and
Refueling chapter for more information
about having your vehicle serviced. See
Emission Control System (page 197).

If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately.

WARNING

Under engine misfire conditions,
excessive exhaust temperatures
could damage the catalytic

converter, the fuel system, interior floor
coverings or other vehicle components,
possibly causing a fire. Have your vehicle
checked as soon as possible.

The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb
and to indicate whether the vehicle is ready
for Inspection/Maintenance (I/M) testing.

Normally, the service engine soon light will
stay on until the engine is cranked, then
turn itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See Emission Control
System (page 197).

a Diesel Engine (page 176).

Water In Fuel

(If Equipped)

During refueling, it is possible for
you to pump
water-contaminated diesel fuel

into your fuel tank. Your vehicle’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.

If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 185).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.

WARNING

Do not drain the water-in-fuel
separator while the engine is running.
Failure to follow this warning may

result in fire, serious injury, death or
property damage.

Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.
