that the anti-lock portion of the brake system is not 
functioning and that service is required. See your autho-
rized dealer immediately. The ABS light could also
illuminate during loss of traction and remain illuminated
until the brake pedal is pressed. 
20. Cargo Light 
The Cargo Lamp light will illuminate when the Cargo
Lamp is activated by pressing the Cargo Light Button on
the headlight switch. 
21. Electronic Throttle Control (ETC) This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your 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. The light will
come on when the ignition is first turned on and remain
on for 15 seconds as a bulb check. If the light does not
come on during starting, have the system checked by an
authorized dealer. 
22. SERV 4WD Indicator 
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required. 
23. Front Fog Light Indicator — If Equipped 
This light shows when the front fog lights are ON.
