2-15 Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY message to go out.
4. Then reach in through the window, unlock the 
door with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should but the
vehicle's headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace the 
fuse, see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
If the engine stalls and the SECURITY message flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuse (see ªFuses
and Circuit Breakersº in the Index). See your dealer 
for service.
In an emergency, call the Cadillac Roadside Service
Center. See ªRoadside Serviceº in the Index.

Engine Coolant Heater (If Equipped)
In very cold weather, 
0F (
-18C) or colder, 
the engine coolant heater
can help. You'll get easier
starting and better fuel
economy during engine
warm
-up. Usually, the
coolant heater should be
plugged in a minimum of
four hours prior to starting
your vehicle.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. 
The cord is located on the driver's side of the vehicle
in the engine compartment, near the power steering
fluid reservoir.3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, 
use a heavy
-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug 
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could 
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for 
that particular area.

DRIVE (D): This position is for normal driving. If you
need more power for passing, and you're:
Going less than about 35 mph (56 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
DRIVE (D) can be used when towing a trailer, carrying
a heavy load, driving on steep hills or for off
-road
driving. You may want to shift the transmission to
THIRD (3) or, if necessary, a lower gear selection if the
transmission shifts too often.
THIRD (3): This position is also used for normal
driving, however it offers more power and lower fuel
economy than DRIVE (D).SECOND (2): This position gives you more power but
lower fuel economy. 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.
If you manually select SECOND (2) the transmission
will drive in second gear. You may use this feature for
reducing the speed of the rear wheels when you are
trying to start your vehicle from a stop on slippery 
road surfaces. Once the vehicle is moving, shift 
into DRIVE (D).
FIRST (1): This position gives you even more power
(but lower fuel economy) 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) while the vehicle 
is moving forward, the transmission won't shift into 
first gear until the vehicle is going slow enough.

Instrument Panel Cluster
United States shown. Canada similar.
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know 
how fast you're going, about how much fuel you have and many other things you'll need to know to drive safely 
and economically.

The TRAC OFF light may come on for the 
following reasons:
If you turn the system off by pressing the TCS on/off
button located to the right of the steering wheel, the
light will come on and stay on. To turn the system
back on, press the button again; the light should 
go off.
If you move the shift lever to FIRST (1), the light
will come on and stay on to indicate that the Traction
Control System is off. This is normal operation. 
To turn the system back on, move the shift lever
back to a position other than FIRST (1); the light
should go off. See ªTraction Control Systemº in 
the Index.
The light will come on and stay on if the TCS
automatic engagement feature has been turned off.
To turn the system on, press the TCS off/on button;
the light should go off. To turn the automatic
engagement feature back on, see ªTraction Control
Systemº in the Index.
If the Traction Control System is affected by an
anti
-lock brake system, Traction Control System or
engine
-related problem, the system will turn off and
the light will come on. Have your vehicle serviced.If the vehicle is driven over an extremely rough road,
the system will turn off and the light will come on.
The light will go off a few seconds after the rough
road conditions go away or when the vehicle comes
to a complete stop. This is normal operation.
Malfunction Indicator Lamp (Service
Engine Soon Light in the United States 
or Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.

This system is called OBD II (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. The SERVICE ENGINE SOON or
CHECK ENGINE 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.
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.
NOTICE:
Modifications made to the engine, transmission,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE SOON or
CHECK ENGINE light to come on.
Modifications to these systems could lead to
costly repairs not covered by your warranty. 
This may also result in a failure to pass a
required Emission Inspection/Maintenance test.
