1999 CADILLAC DEVILLE service

With the ignition key in the ignition switch, you can turn
the switch to five different positions.
ACCESSORY (A): This position lets you use things
like the radio and the windshield wipers when the
engine is off. To get into ACCESSORY, push in the key
and turn it toward you. The steering wheel will remain
locked, just as it was before you inserted the key.
LOCK (B): Before you put the key in, the ignition will
be in LOCK. This is the only position in which you can
remove the key. This position locks the ignition, steering
wheel and transaxle. It's a theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK does. Use OFF if you must have your
vehicle in motion while the engine is off (for example, if
your vehicle is being pushed).
RUN (D): This position is for driving.
START (E): This position starts the engine.
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
RUN to OFF:

Radio

Power Windows

Sunroof
Power to these accessories stops after 10 minutes or
if any door is opened. If you want power for another
10 minutes, turn the ignition key to RUN, then back
to OFF, then to LOCK. Always leave your key in
LOCK when using RAP. If you leave your key in
any other position than LOCK, your battery will
discharge prematurely.

OVERDRIVE (
): This position is for normal driving.
If you need more power for passing, and you're:

Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it doesn't seem to shift gears as you accelerate,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and OVERDRIVE (
)
for higher speeds.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than OVERDRIVE (
).
Here are examples for using THIRD (3) instead of
OVERDRIVE (
):

When driving on hilly, winding roads.

When towing a trailer, so there is less shifting
between gears.

When going down a steep hill.
SECOND (2): This position gives you more power. You
can use SECOND (2) on hills. It can help control your
speed as you go down steep mountain roads, but then
you would also want to use your brakes off and on.
NOTICE:
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.

2-26
FIRST (1): This position gives you even more power
than SECOND (2). You can use it on very steep hills,
or in deep snow or mud. (If the shift lever is put in
FIRST (1), the transaxle won't shift into gear until the
vehicle is going slowly enough.)
NOTICE:
If your front wheels can't rotate, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could cause overheating and damage
the transaxle. Use your brakes to hold your
vehicle in position on a hill.
Parking Brake
Hold the regular brake
pedal down with your right
foot and push the parking
brake pedal down with your
left foot to set the parking
brake. If the ignition is on,
the PARK BRAKE
indicator light should come
on. If it doesn't, you need to
have your vehicle serviced.
If the parking brake has not been fully released and you
try to drive off with the parking brake on, the PARK
BRAKE indicator light comes on and stays on. See
ªParking Brake Indicator Lightº in the Index for
more information.
When you move out of PARK (P) or NEUTRAL (N),
if the engine is running, the parking brake should
release. If it doesn't, you can manually release the
parking brake.

CAUTION:
Always shift to PARK (P) before pulling the
manual release lever. If your hand or arm is in
the way of the pedal you could be hurt. The pedal
springs back quickly. Keep your hand and arm
away when you use the manual release lever.
Before releasing the manual parking brake, be sure to put
the vehicle in PARK (P) and turn the ignition to OFF.
Reach under the driver's side of the instrument panel
and pull on the manual release lever, which is located
above the parking brake pedal. If the parking brake does
not release, you should either drive to the nearest service
station or have your vehicle towed.

When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle also has a Driver Information Center that
works along with the warning lights and gages. See
ªDriver Information Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds,
then it will flash for
about 70 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-69 Charging System Light
When you turn the
key to RUN, 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 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 RUN. 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.)
