• Turn Signal Indicators - The two turn signal
indicators are integral to the ElectroMechanical
Instrument Cluster (EMIC) located in the instrument
panel.
• Turn Signal Lamps - The front turn signal
lamps are integral to the front park/turn signal
lamps located beside each headlamp on the front
fender. The rear turn signal lamps are integral to the
back-up/brake/rear turn signal/tail lamps located on
either side of the rear of the quarter panels.
• Turn Signal Switch - The turn signal switch is
integral to the left multi-function switch. The left
multi-function switch control stalk actuates the turn
signal switch in the steering column.
The turn signal system in this vehicle includes a
turn signal-on warning chime feature. The EMIC
electronic circuitry monitors the turn signal indica-
tors as well as electronic vehicle speed and distance
messages received from the PCM over the PCI data
bus network to provide this feature. If an indicator
remains illuminated continuously with the vehicle
speed above about 25 kilometers per hour (15 miles
per hour) for a distance of greater than about 1.6
kilometers (1 mile), the EMIC generates a chime
through an integral chime tone generator (The dis-
tance is greater for export vehicles).
Hard wired circuitry connects the turn signal and
hazard warning system components to each other
through the electrical system of the vehicle. Refer to
the appropriate wiring information.
DESCRIPTION - HEADLAMP LEVELING
SYSTEM
Some vehicles are equipped with a remote head-
lamp leveling system. This system allows the driver
to adjust the headlamp beam pattern from the inte-
rior of the vehicle to compensate for passenger or
cargo load. Only the vertical axis of the headlamp
beam can be adjusted (Fig. 1).
A headlamp leveling switch is located on the
instrument panel and controls the headlamp leveling
motors/modules found on the headlamp modules.
Leveling switch has four settings 0-3. A higher num-
ber results in a lower headlight beam relationship to
the road surface.
When performing a headlamp beam pattern align-
ment on a vehicle equipped with headlamp leveling,
be certain the headlamp leveling switch is in the "0"
position before starting. Failure to do so will result in
and incorrect headlamp alignment.
OPERATION - TURN SIGNAL & HAZARD
WARNING SYSTEM
The turn signal system operates on battery voltage
received on a ignition switch output (run) circuit so
that the turn signals will only operate with the igni-

tion switch in the On position. The hazard warning
system operates on non-switched battery voltage so
that the hazard warning remains operational regard-
less of the ignition switch position. When the turn
signal switch control stalk is moved up or down, the
turn signal system is activated. When the turn signal
system is activated, the circuitry of the turn signal
switch and the combination flasher will cause the
selected turn signal indicator, front park/turn signal
lamp, front side marker lamp, repeater lamps, and
rear tail/stop/turn signal lamp to flash on and off.
When the hazard warning system is activated, the
circuitry of the hazard warning switch and the com-
bination flasher will cause both the right side and
the left side turn signal indicators, front park/turn
signal lamps, front side marker lamps, repeater
lamps and rear tail/stop/turn signal lamps to flash on
and off.
In order to provide the turn signal-on warning, the
ElectroMechanical Instrument Cluster (EMIC) moni-
tors vehicle speed and distance messages received
from the PCM over the PCI data bus and the hard
wired turn signal switch input to the cluster elec-
tronic circuit board. If a turn signal remains indi-
cated for a distance of greater than about 1.6
kilometers (1 mile) and the vehicle speed remains
greater than about 24 kilometers-per-hour (15 miles-
per-hour), the EMIC generates a repetitive chime at
a slow rate to provide an audible reminder that a
turn signal has been left on (distance is slightly
longer with export vehicles). Once the warning chime
