192 GETTING TO KNOW YOUR INSTRUMENT PANEL
— Cruise Control Ready Indicator
This indicator light will illuminate when the cruise control is
ready, but not set. Refer to “Speed Control” in “Starting And
Operating” for further information.
— Hill Descent Control (HDC) Indicator Light — If
Equipped
This indicator shows when the Hill Descent Control (HDC)
feature is turned on. The lamp will be on solid when HDC is
armed. HDC can only be armed when the transfer case is in
the “4WD LOW” position and the vehicle speed is less then
20 mph (32 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC indicator light
will flash on/off.
Blue Indicator Lights
— High Beam Indicator Light
This indicator light will illuminate to indicate that the high
beam headlights are on. With the low beams activated, push
the multifunction lever forward (toward the front of the
vehicle) to turn on the high beams. Pull the multifunction
lever rearward (toward the rear of the vehicle) to turn off the
high beams. If the high beams are off, pull the lever toward
you for a temporary high beam on, "flash to pass" scenario.
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 transmission
control systems. When these systems are operating properly,
your vehicle will provide excellent performance 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 an
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 emissions tests can be
performed.
• If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss will
soon occur. Immediate service is required.
