6. 4 LOW
This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels.
7. Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned to ON/RUN and remain on briefly as a
bulb check. If the light does not come on during starting,
have the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position, the light should turn off.
If the light remains lit with the engine running, your
vehicle will usually be drivable; however, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing.
For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC) — If Equipped” for further information.
8. 4WD Indicator
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simultane-
ously.
