2004 CADILLAC DEVILLE warning light

Tachometer (Analog Cluster Only)
This gage indicates
the engine speed in
revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Engine Speed Limiter
This feature prevents the engine from operating at too
many revolutions per minute (rpm). When the engine’s
rpm are critically high, the fuel supply to the engine
is shut off. When the engine speed slows, the fuel
supply will come on again. This helps prevent damage
to the engine.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts.
The safety belt light will
also come on and stay on
for several seconds. If
the driver’s belt is already
buckled, the light will
come on briey, but the
chime will not sound.

Brake Indicator Light
Your vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can

Have your brake system inspected right away.
This light should come on
briey when you turn the
ignition key to ON. If it
does not come on
then, have it xed so it will
be ready to warn you if

The light will stay on if your parking brake does not fully
release. If it stays on after your parking brake is fully
released, it means you have a brake problem.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,

on for several seconds.
That is normal.
If the light stays on, turn the ignition to OFF. Or, if the light
comes on when you are driving, stop as soon as possible
and turn the ignition off. Then start the engine again to
reset the system. If the light still stays on, or comes on
again while you are driving, your vehicle needs service. If
the regular brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes. If the
regular brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with your
regular brakes. SeeBrake System Warning and Parking
Brake Indicator Light on page 3-51.

The battery should recharge while driving but may
take a few hours to do so. Consider using an auxiliary
charger (be sure to follow the manufacturer’s
instructions) to boost the battery after returning home or
to a nal destination. If this message appears while
driving or after starting your vehicle and stays on, have
it checked immediately to determine the cause of
this problem. To help the generator recharge the battery
quickly, you can reduce the load on the electrical
system by turning off the accessories. You can monitor
battery voltage on the DIC by pressing the INFO
button. The normal range is 11.5 to 15.5 volts.
