Turn and Lane-Change Signals An arrow on the instrument panel cluster flashes in the direction of the turn or lane change. Headlamp High/Low-Beam Changer To change the headlamps from low beam to high beam, push the turn signal/multifunction lever away from you. This instrument panel cluster light 3 comes on if the high beam lamps are turned on while the ignition is in ON/RUN. To change the headlamps from high beam to low beam, pull the turn signal lever toward you. Move the lever up or down to signal a turn. Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is complete. The lever returns to its original position whenever it is released. If after signaling a turn or lane change the arrow flashes rapidly or does not come on, a signal bulb may be burned out. Have the bulbs replaced. If the bulb is not burned out, check the fuse. See Taillamps, Turn Signal, Sidemarker, Stoplamps and Back-up Lamps on page 5-50 for turn signal bulb replacement procedures and Fuses and Circuit Breakers on page 5-99 for location of fuses. A chime will sound if the turn signal is left on for more than 3/4 mile (1.2 km). 3-8 Flash-to-Pass This feature lets you use your high-beam headlamps momentarily to signal a driver in front of you that you want to pass. To use it, pull the turn signal/multifunction lever toward you until the high-beam headlamps come on, then release the lever to turn them off.
