• High beam headlight operation illumi¬
nates the inboard blue lens.
Rear Monitor
• Taillight operation on left or right side
illuminates the corresponding red lens.
• Turn signal, hazard flasher, and brake
light operation is indicated by increased
light intensity from the corresponding
monitor lens.
Side Marker Lights
Your Cadillac is equipped with front and
rear side marker lights that provide additional
side identification so the car is more visible to
other motorists at night. Whenever the head¬
lights or parking lights are on, the front (amber)
and rear (red) side marker lights are on.
Guide-Matic Headlight
Control
The Guide-Matic Headlight Control (on
cars so equipped) switches the headlights au¬
tomatically while driving in darkness. Fig.

.
Operation
• Set control ring pointer on headlight con¬
trol to "OFF" position.
• Select high beam with the foot operated
dimmer switch.
• Set control ring pointer on "FAR". On¬
coming headlights will cause the system
to dim your headlights automatically.
After traffic passes, move pointer slowly
away from "FAR" until lights switch to high
beam. The system is then set for automatic
dimming at maximum distance.
• To delay dimming until oncoming traffic
is closer, rotate control ring pointer farther
away from "FAR".
• For non-automatic control of headlight
beam, rotate pointer to "OFF" and use the
foot dimmer switch.
Tips
• If Guide-Matic has not switched to
"DIM", you may dim the headlights with
the foot switch while the system is on
automatic high beam.
• High beams can be switched on momen¬
tarily for signaling when the system is in
automatic low beam by applying slight

downward pressure to the foot dimmer
switch.
Twilight Sentinel
The Twilight Sentinel system (on cars so
equipped) senses outside light and automati¬
cally turns the lights on as darkness ap¬
proaches, and turns them off as daylight re¬
sumes: A system delay of usually less than 30
seconds prevents the lights from automatically
switching on when passing under bridges,
trees, etc. The delay also prevents the lights
from switching off automatically when pas¬
sing under bright lights.
