Testing the Alarm
1.
From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2.
From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry transmitter and close the door.
Wait 30 seconds until the SECURITY light goes off.
3.
Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
headlamps will flash.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see “Fuses and Circuit Breakers” in the
Index. If the fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always activate the
theft
-
deterrent system when leaving your vehicle.
Valet Lockout Switch
The valet lockout switch is
located inside the glovebox.
Pushing the VALET lockout switch to ON will disable
the use of the power trunk, fuel door and garage door
openers. Pushing the switch to OFF again will make
these features reusable. Locking the glove box with the
key will also help to secure your vehicle.
The remote keyless entry transmitter cannot be used to
open the trunk or fuel door if the valet lockout switch is
in the ON position. Also, the valet key will not unlock
the glovebox or trunk.

Key III
(Personalized Automotive Security System)
theft
-
deterrent system. PASS
-
Key III 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.
Your PASS
-
Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-
210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an

PASS
-
Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-
Key III system senses that someone is
using the wrong key, it shuts down the vehicle’s starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-
and
-
error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
If the engine does not start, and the key appears to be
undamaged, try another ignition key. At this time, you
may also want to check the fuse (see “Fuses and Circuit
Breakers” in the Index). If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the first key may be faulty. See your
dealer or a locksmith who can service the PASS
-
Key III
to have a new key made.

Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is complete.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it’s released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.
Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers won’t see the turn signal.
Replace burned
-
out bulbs to help avoid possible
accidents. Check the fuse (see “Fuses and Circuit
Breakers” in the Index) and for burned
-
out bulbs if the
arrow fails to work when signaling a turn.
Headlamp High/Low Beam
Push forward for high beam to change the headlamps
from low beam to high. Pull the lever back and then
release it to change from high beam to low.
This light located on the
instrument panel will be on,
indicating high
-
beam usage.
Flash-To-Pass
This lets you use the high beam headlamps to signal the
driver in front of you that you want to pass.
Pull and hold the turn signal lever toward you to use.
When you do:
D
If the headlamps are either off or in the DRL mode,
the high beam headlamps will turn on. They’ll stay
on as long as you hold the lever there. Release the
lever to turn them off.
D
If the headlamps are on highbeam, they will switch
to low beam. To return to high beam, push the lever
away from you.

Cellular Telephone (Option)
Your vehicle has been prewired for dealer installation of
the Cadillac Communiport
t
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 “Inadvertant Power Battery Saver” 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.

Adding Coolant
If you need more coolant, add the proper DEX
-
COOL
R
coolant mixture
at the surge tank
, but only when the
engine is cool.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When replacing the pressure cap, make sure it is hand
-
tight.
Surge Tank Pressure Cap
NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure
-
type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrow on the cap
lines up with the overflow hose.
Power Steering Fluid
The power steering fluid
reservoir is located between
the fuse block relay center
and the engine on the
passenger’s side of
the vehicle.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
6-28
How to Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then remove the cap again and
look at the fluid level on the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in the
Maintenance Schedule booklet. Always use the proper
fluid. Failure to use the proper fluid can cause leaks and
damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
The CHECK WASHER FLUID message will be
displayed on the Driver Information Center (DIC) when
the fluid is low.
The windshield washer fluid reservoir is located in front
of the fuse block relay center on the passenger’s side of
the vehicle.
Open the cap labeled WASHER FLUID. Add washer
fluid until the tank is full.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add
-
on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see “Servicing
Your Air Bag
-
Equipped Vehicle” in the Index.
Headlamp Wiring
The headlamp wiring system has four individual fuses,
LF low, RF low, LF high and RF high. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have the
headlamp wiring checked right away.
Windshield Wiper Fuses
A circuit breaker protects the wiper motor. If the wiper
motor overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
A MiniFuse
R
powers the wiper motor. If the MiniFuse
blows, there is an electrical problem. Be sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is fixed or goes away.
6-64
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires caused
by electrical problems.
Look at the silver
-
colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating. If a MaxiFuse should blow, see your dealer
for service immediately.
If you ever have a problem on the road and don’t have a
spare fuse, you can “borrow” one that has the same
amperage. Pick some feature of your vehicle that you
can get along without
--
like the radio or cigarette
lighter
--
and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine
compartment on the passenger’s side and the other under
the rear seat on the driver’s side. If a MaxiFuse should
blow, have your vehicle serviced by your
dealer immediately.
Underhood Junction Block
The front Bussed Electrical Center (BEC) is located
next to the engine on the passenger’s side of the vehicle.
To access the fuse block, push in the two tabs located on
the top and the bottom of the fuse block cover.
