Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned from
ON to OFF:

Radio

Power Windows

Sunroof
Power to these accessories will stop after 10 minutes or
if any door is opened. If you want power for another
10 minutes, turn the ignition key to ACCESSORY, then
back to OFF. Always leave your key in OFF when using
RAP. If you leave your key in any other position than
OFF, your battery will discharge prematurely.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.

Starting Your Northstar V8 Engine
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor. Wait about 15 seconds
between each try to help avoid draining your
battery or damaging your starter.
2. If it doesn't start right away, hold your key in
START for about three seconds at a time until your
engine starts. Wait about 15 seconds between each
try to help avoid draining your battery or damaging
your starter.3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.

2-35
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is in ON. See ªAutomatic Transaxleº in
the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want. If you ever
hold the brake pedal down, but still can't shift out of
PARK (P) and your vehicle has a column shifter,
try this:
1. Turn the ignition key to ACCESSORY.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.
Shift Lock Release (Console Shifter Only)
This vehicle is equipped with an electric shift lock
release system. The shift lock release is designed to:

Prevent ignition key removal unless the shift lever is
in PARK (P), and

Prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than OFF.
The shift lock release is always functional except in
the case of a dead battery or low voltage (less
than 9 V) battery.
If your vehicle has a dead battery or a battery with low
voltage, there is an override access hole that will allow
you to override the shift lock release.

Exterior Lighting Battery Saver
If the headlamp or manual parking lamp control
has been left on, the exterior lamps will turn off
approximately 10 minutes after the ignition is turned to
OFF. This protects draining the battery in case you have
accidentally left the headlamps or parking lamps on. If
you need to purposely leave the lamps on for more than
10 minutes with the ignition in OFF or ACCESSORY,
turn the manual control knob off and then back on.
To delay the lamps from turning off, see ªTwilight
Sentinelº in the Index.
If the headlamp switch is turned on after the ignition key
is moved to either OFF or ACCESSORY, the lamps will
not time out.
Interior Lamps
Instrument Panel
Intensity/Brightness Control
The displays automatically dim when it becomes dark
outside and your lights are on. The displays
automatically brighten when it becomes light outside.
Backlighting will only remain active as long as the
parking lamps are on and it is dark outside.
Courtesy Lamps
The courtesy lamps are located on the ceiling above the
rear seat. These lamps come on with the control lamp
knob or when any door is opened and it is dark outside.
Puddle lamps are located on the bottom of the front and
rear door trim.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the
illuminated entry system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn on.
The courtesy lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.

2-53
Battery Load Management
The battery load management feature is designed to
monitor the vehicle electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher RPM setting than normal to make sure the battery
charges. High electrical loads may occur when several
of the following are on: headlamps, high beams, fog
lamps, rear window defogger, high blower fan, heated
seats and engine cooling fans.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp, glove
box lamp, cigarette lighters or the garage door opener.
When the ignition is turned off, the power to these features
will automatically turn off after 10 minutes (three minutes
if a new car has 15 miles (24 km) or less). Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.
Mirrors
Electrochromic Day/Night Rearview Mirror
with Compass (If Equipped)
Your vehicle may have an electrochromic inside
rearview mirror with a compass.
By pressing the MIRROR side of the button located at
the bottom of the mirror, the mirror automatically
darkens to reduce the glare from headlamps behind you.
The mirror also includes an eight
-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.

Cellular Telephone (Option)
Your vehicle has been prewired for dealer installation of
the Cadillac Communiport
integrated portable cellular
telephone system. The system has steering wheel
telephone controls and information output through the
Driver Information Center (DIC). Voice activation with
remote record and hands
-free operation are standard
features. For more information, contact your dealer. A
user's guide is provided with the telephone.
Accessory Power Outlets (If Equipped)
Your vehicle may be equipped with accessory power
outlets that can be used to power additional devices
designed to operate with vehicle electrical systems. The
accessory power outlets are located in the center storage
compartment of the instrument panel and under each
storage lid of the rear door armrests. When the ignition
is on, or up to 10 minutes after the ignition is turned off,
you can plug in accessories that require electrical power.
Power to the outlets will shut off 10 minutes after the
ignition is turned off to help prevent the battery from
draining. See ªInadvertant Power Battery Saverº in the
Index. Power supply to the accessory power outlets or
cigarette lighters can be changed from 10 minutes to full
time by changing some fuses. See your dealer
for assistance.Leaving an accessory on for an extended period of time
(i.e. airport stay or storage) or if a fuse is in the wrong
place may drain the vehicle's battery.

Charging System Light
When you turn the key to
ON, this light will come on
briefly to show that the
generator and battery
charging systems
are working.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save your
battery until you get there, turn off all accessories.
Brake System Warning and Park Brake
Indicator Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you turn the
ignition key to ON. If it
doesn't come on then, have
it fixed so it will be ready
to warn you if there's
a problem.
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 floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See ªTowing Your Vehicleº
in the Index.)

Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON or CHECK ENGINE light is
on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center
to prepare the vehicle for inspection.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON. It goes
off once you start your engine. That's a check to be sure
the light works. If it doesn't come on, be sure to have it
fixed so it will be there to warn you if something
goes wrong.
When the light comes on and stays on, it means that oil
isn't flowing through your engine properly. You could
be low on oil and you might have some other
system problem.
