2-100
BATTERY VOLTAGE LOW - 6: This message
will appear when the electrical system is charging less
than 10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may take a
few hours to do so. Consider using an auxiliary charger
(be sure to follow the manufacturer's instructions) to
boost the battery after returning home or to a final
destination. If this message appears while driving or
after starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by turning off
the accessories. You can monitor battery voltage on the
DIC by pressing the INFO button. The normal range
is 11.5 to 15.5 volts.
CHANGE ENGINE OIL
- 82: This means that the
life of the engine oil has expired and it should be
changed within 200 miles. See ªEngine Oilº and
ªFilter Recommendationsº in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must
be reset. See ªOil Life Indicator, How to Resetº in
the Index.CHANGE TRANS FLUID
- 47: This message will
appear when it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid
and change intervals.
CHECK BRAKE FLUID
- 37: This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See ªBrake
System Warning Lightº in the Index.
CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.
CHECK FUEL GAGE
- 50: (Analog Cluster Only)
This message will appear when the fuel supply is less
than 5 gallons (18.9 L) and the display is turned off.
A single chime will also sound when this message
is displayed.
CHECK GAS CAP
- 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's fully tightened.

2-101
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground with
the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick.
Prior to checking the oil level, be sure the engine has
been off for a few minutes and your vehicle is on a
level surface. Then check the dipstick and add oil if
necessary. See ªEngine Oilº in the Index.
CHECK TIRE PRESSURE
- 144: This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button
up or down the DIC display will show which tire or tires
do not have the correct inflation pressure. A ªLOW TIREº condition exists when the tire's air
pressure is under 24 psi (165 kPa) and a ªHIGH TIREº
condition exists when the tire's air pressure is above
36 psi (248 kPa).
The system will display the air pressure, the tire location
(LF, RF, RR or LR) and if the air pressure is low or
high. The tire pressure information is available in
English or metric measurements. For example, a driver's
side front tire that is low may be shown as: 22 PSI LF
TIRE LOW.
The correct tire inflation pressure should be set to those
shown on the Tire Loading
-Information Label, located on
the rear edge of the driver's door. For more information
regarding proper tire inflation, see ªInflation
-- Tire
Pressureº in the Index. If a tire is low, you should stop
as soon as possible and inspect your tire(s) for damage.
If a tire is flat, see ªIf a Tire is Flatº in the Index.

2-104
OIL PRESSURE LOW STOP ENGINE - 35: If this
message appears while the engine is running, stop the
engine and do not operate it until the cause of low oil
pressure is corrected. Severe damage to the engine can
result. A multiple chime will also sound when this
message is displayed.
PASSENGER DOOR AJAR
- 141: The right front
passenger's door is open or ajar when this message
appears. The ignition must be in ON and the transaxle
not in PARK (P) for this message to display. A chime
will also sound when the vehicle's speed is greater than
3 mph (5 km/h).
RIGHT REAR DOOR AJAR
- 143: The right
rear door is open or ajar when this message appears.
The ignition must be in ON and the transaxle not in
PARK (P) for this message to display. A chime will
also sound when the vehicle's speed is greater
than 3 mph (5 km/h).
SERVICE AC SYSTEM
- 14: This message
appears when the electronic sensors that control the air
conditioning and heating systems are no longer working.
Have the climate control system serviced if you notice a
drop in heating and air conditioning efficiency.SERVICE AIR BAG
- 83: There is a problem with
the supplemental inflatable restraint (air bag) system
when this message appears. Let only a qualified

Comfort Controls and Radio
System Personalization
These features allow both drivers to personalize their
own climate control settings as well as their radio
settings. For more information, see ªClimate Control
Personalizationº and ªRadio Personalizationº in
the Index.
Continuous Variable Road Sensing
Suspension (CVRSS) (If Equipped)
The CVRSS automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response.
If the controller detects a problem within the system,
the DIC will display a SERVICE SUSPENSION SYS
message. If this message appears, have your vehicle
serviced at your dealership.
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and your
driving patterns. To see the display, press the INFO
button several times until ENGINE OIL LIFE appears.
If you see 99% ENGINE OIL LIFE, 99 percent of your
current oil life remains.

2-114
The DIC may display a CHANGE ENGINE OIL
message. Always keep a written record of the mileage
and date when you changed your oil. For more
information, see the Maintenance Schedule booklet.
If you see CHANGE ENGINE OIL, it means the
oil life is gone and you should change the oil right away.
The system doesn't check how much oil you have,
so you'll still have to check for that. To see how,
see ªEngine Oilº in the Index.
When the oil is changed, you'll need to reset the system.
See ªOil Life Indicator, How to Resetº in the Index.Night Vision System (Option)
The Night Vision System can help you see better when
you drive at night. The system works by sensing heat
given off by objects in its field of view. Warmer objects,
such as pedestrians, animals and other moving vehicles,
will appear whiter. Colder objects, such as the sky, signs
and parked vehicles, will appear darker.

4-23
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit,
do not, under any circumstances, stop and back up.
Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Cadillac dealerships all across North America.
They'll be ready and willing to help if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated
to the recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

4-39 Parking on Hills
CAUTION:
You really should not park your vehicle, with
a trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but do not shift
into PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brakes.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule booklet
for more on this. Things that are especially important in
trailer operation are automatic transaxle fluid (don't
overfill), engine oil, drive belt, cooling system and brake
system. If you're trailering, it's a good idea to review
this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

5-9
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº and ªRecreational Vehicle Towingº in
the Index.
Engine Overheating
You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message on the Driver Information
Center (DIC). You will also hear a chime. There is
also an engine temperature warning light and/or gage
on the instrument panel cluster. See ªEngine Coolant
Temperature Warning Lightº or ªEngine Coolant
Temperature Gageº in the Index.
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED, STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle
to be driven to a safe place in an emergency; you may
drive up to 50 miles (80 km). Towing a trailer in the
overheat protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and
reset the oil life indicator. See ªEngine Oilº in
the Index.
