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 -

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.

washer fluid,
a rag, some winter outer clothing, a small shovel, a
flashlight, a red cloth, and a couple of reflective warning triangles. And,
if
you will be driving under severe conditions, include a small bag of sand, a
piece of old carpet or a couple of burlap bags to help provide traction. Be
sure you properly secure these items
in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the road probably
have good traction.
However,
if there is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have
a lot less traction or “grip” and
will need to be very careful.

Safety Chains
You should always attach chains between your vehicle and your trailer.
Cross the safety chains under the tongue of the trailer so that the tongue
will not drop to the road
if it becomes separated from the hitch. Follow
the manufacturer’s recommendation for attaching safety chains. Always
leave just enough slack
so you can turn with your rig. And, never allow
safety chains to drag
on the ground.
Trailer Brakes
Be sure to read and follow the instructions for the trailer brakes so you’ll
be able to install, adjust and maintain them properly.
Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting
out for the open road, you’ll want to get to
know your rig. Acquaint
yourself with the
feel of handling and braking with the added weight of
the trailer. And always keep
in mind that the vehicle you are driving is
now a good deal longer and not nearly
so responsive as your vehicle is by
itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the brakes are working. This
lets you check your electrical connection at the same time.
During your trip, check occasionally to be sure that the load is secure,
and that the lights and any trailer brakes are still working.
