1997 GMC SAVANA ignition

When the wheel is turned to full brilliance, and then into
the first detent position, the radio display and PRNDL
display will go to the day mode (full intensity). This is
known as “parade” mode. The rest
of the I/P
illumination will stay in the maximum dimming state
(full brilliance dimming). Turning the wheel up one
more detent will activate the interior dome light circuit
(with slightly higher effort).
The dome lights cannot be turned on by depressing the
dome light switch button, located below the parkhead
lamp switch knob. This switch is a dome lamp off
switch and will only interrupt inputs from the door jamb
switches, inhibiting interior light operation when
depressed. It will not inhibit the light function from the
I/P dimmer switch.
The delayed entry will allow
you to enter or exit your
vehicle with the lights staying
on for about 20 seconds
after the door
is closed or ignition is cycled.
Rotate the switch knob clockwise to the parking lamp
symbol to turn on:
0 Parking Lamps
0 Sidemarker Lamps
0 Taillamps
License Plate Lamps
Instrument Panel Lights
0 Ashtray Lamp
0 Glove Box Lamp
Rotate the switch
knob clockwise again to the master
lighting symbol to turn on all the lamps listed above as
well as the headlamps.
Rotate the switch counterclockwise to
OFF to turn off
your lamps and lights.
Rotate the thumb wheel next to the switch knob up to
adjust instrument panel lights. Rotate the thumb wheel
up to the first notch to return the radio display and
gearshift indicator Vacuum Fluorescence (VF) display
to full intensity when the headlamps or parking lamps
are on.
Rotate the thumb wheel up
to the second notch to
activate the interior dome lamps.
You can switch your headlamps from high to low beam
by pulling
on the turn signalhigh beam lever.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on
and off. Have your headlamp wiring checked right away
if this happens.

Headlamps On Reminder
A tone will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.
If you need to use your headlamps when the ignition
switch is in
OFF, LOCK or ACCESSORY, the tone
can be turned off by turning the thumb wheel
next to
the parking lamp/headlamp switch all the way down.
Daytime Running Lamps (If Equipped)
Daytime Running Lamps (DRL) can make it easier for
others
to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in
the short periods
after dawn and before sunset.
The DRL system will make your headlamps come on at
a reduced brightness when:
0 The ignition is on,
0 The headlamp switch is off, and
0 The parking brake is released.
If your vehicle was first sold, when new,
in Canada,
your headlamps will come on at reduced brightness.
If your vehicle was first sold, when new,
in the United
States, your vehicle may be equipped with DRL. If your
vehicle has DRL,
you will see the the DRL indicator light
on your instrument panel and your low-beam
headlamps will
come on at reduced brightness.
When the DRL are on,
only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be on.
Your instrument panel won’t be lit up either.
When
it begins to get dark, your DRL indicator light is a
reminder
to turn your headlamp switch on. The other lamps
that come on with your headlamps will also come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps will change to
the reduced brightness
of DRL.
To idle your vehicle with the engine on and the DRL off,
set the parking brake. The DRL will stay off until you
release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need
it.
Dome Lamps
The dome lamps will come on when you open the doors.
You can also turn the dome lamps on by rotating the
thumb wheel, located next
to the headlamp knob, all
the way up to the second notch. In this position, the
dome lamps will remain on whether the doors are
opened or closed.

Malfunction Indicator Lamp (Service
Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
SERVICE control systems.
ENGINE SOON
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often
will be indicated
by the system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.

If the Light Is Flashing
I NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered
by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come
on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required. The
following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine. If the light remains
on steady, see “If the Light
