Downloaded from www.Manualslib.com manuals search engine PASS-KEY’II
Your vehicle is equipped with the PASS-Key’II (Personalized
Automotive Security System) theft deterrent system. PASS-Key% is a
passive theft deterrent system. This means you don’t have to do anything
different to arm or disarm the system. It works when you insert or remove
the key from the ignition. PASS-Key’II uses a resistor pellet in the
ignition key that matches a decoder in your vehicle.
When the PASS-Key% system senses that someone is using the wrong
key, it shuts down the vehicle’s starter and fuel systems. For about three
minutes, the starter won’t work and fuel won’t go to the engine.
If
someone tries to start your vehicle again or uses another key during this
time, the vehicle
will not start. This discourages someone from randomly
trying different keys with different resistor pellets
in an attempt to make a
match.
The ignition key must be clean and dry before it’s inserted in the ignition
or the engine may not start.
If the engine does not start and the -
STARTING DISABLED DUE TO THEFT SYSTEM REMOVE L1
IGNITION KEY messgge is displayed the key may be dirty or wet. Turn
the ignition
off.
Clean and dry the key. Wait about three minutes and try again. The
SECURITY light
will remain on during this time. If the starter still won’t
work, and the key appears to be clean and dry, wait about three minutes
and try the other ignition key. At this time, you may also want to check
the fuses (see “Fuses and Circuit Breakers” in the Index). If the starter
won’t work with the other key, your vehicle needs service.
If your vehicle
does start, the first ignition key may be faulty. See your Cadillac dealer or
a locksmith who can service the PASS-K@II.
If you accidentally use a key that has a damaged or missing resistor pellet,
the starter won’t work, you don’t have to wait three minutes before trying
one
of the other ignition keys.
See your Cadillac dealer
or a locksmith who can service the PASS-Key@II
to have
a new key made.

NEW VEHICLE “BREAK-IN”
NOTICE:
Your modern Cadillac doesn’t need an elaborate “break-in.” But
it
will perform better in the long run if you follow these
guidelines:
Don’t drive at any one speed -- fast or slow -- for the first 500
miles (804 km). Don’t make full-throttle starts.
Avoid making hard stops for the first
200 miles (322 km) or
i so. During this time your new brake linings aren’t yet broken
in. Hard stops with new linings can mean premature wear
and earlier replacement. Follow this “breaking-in” guideline
every time you get new brake linings.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If your key seems stuck in “Lock” and you can’t turn it, be sure
it is 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.
STARTING YOUR ENGINE
Move your shift lever to “P” (Park) or “N” (Neutral). Your engine won’t
start in any other position
-- that’s a safety feature. To restart when you’re
already moving, use
“N” (Neutral) only.
NOTICE:
Don’t try to shift to “P” (Park) if your Cad,illac is moving. If you
do, you
could damage the transaxle. Shift to “P” (Park) only
when your vehicle is stopped.
1. Don’tpush the accelerator pedal before starting your engine. In some
other vehicles you might need to do this, but because
of your vehicle’s
computer systems, you don’t.
2. 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.
3. 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.

This position
is for normal driving. If you need more power for

- Going about 35 mph (56 km/h) or more, push the accelerator all
pedal about halfway down.
the way down.
You’ll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems IO start up rather slowly, or if it seems not
to shift gears as you
go faster, 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 “2” (Second Gear)
when you are driving less than
35 mph (56 km/h) and @
(Overdrive) for higher speeds.
3 (Third Gear)
This
is like @, but you never go into Overdrive.
Here are some times you might choose
“3” instead of @:
- When driving on hilly, winding roads
- When towing a trailer, so there is less shifting between gears
- When going down a steep hill

brake system inspected right away.
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 “Towing Your Cadillac” in the Index.)
A CAUTIEON
Your brake system may not be working properly if the brake
system warning li’ght is on. Driving with the brake system
warning light
on can lead to an accident. If the light-is still on
after you’ve pulled off the road and stopped carefully, have the
vehicle
towed for service.
The brake system warning light will also come on when you set your
parking brake, and it
will stay on if your parking brake doesn’t release
fully.
If it stays on after your parking brake is fully released, it means you
have a brake problem.
Anti-Lock Brake System Warning Light
ANTI-
LOCK (@)
With anti-lock,this
light will come on
when you start your
engine and may stay
on for several
seconds. That’s

Downloaded from www.Manualslib.com manuals search engine If the light stays on, turn the ignition off. Or, if the light comes on when
you’re 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’re driving, your Cadillac needs service. If the
regular brake system warning light isn’t on,
you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system warning light is
also on, you don’t have anti-lock brakes and there’s a problem with your
regular brakes. See “Brake System Warning Light” earlier
in this part.
The anti-lock brake system warning light may also come on when you are
driving with a compact spare tire. If this happens, the light means you
won’t have anti-lock until you replace the compact spare with a full-size
tire.
If the warning light stays on after you replace the compact spare with
a full-size tire, or if it comes on again when you’re driving, your Cadillac
needs service.
