I/M testing. See the Readiness for Inspection/Maintenance (I/M)
testing
in the Maintenance and Specifications chapter.

Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II) in the Maintenance and Specifications
chapter. 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 by your authorized dealer.

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.

Electronic throttle control
(RTT) (if equipped):
Displays
when the engine has defaulted to a
“limp-home” operation. Report the
fault to a dealer at the earliest opportunity.

The message center will also display ENGINE FAILSAFE MODE. Refer to
Message center in this chapter.

Check 4X4 (RTT) (if equipped):
Displays with the message CHECK
4X4 when a four-wheel drive fault is
present.

Refer to Message center in this chapter.

Brake system warning light: To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position.

If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer.
