Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that
are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed in English.
BATTERY NOT CHARGING - 7: This message will
appear if the battery is not being charged. Have the
electrical system checked by your dealership at your
earliest convenience.
BATTERY SAVER ACTIVE - 27: This message is
displayed when the vehicle has detected that the battery
voltage is dropping beyond a reasonable point. The
battery saver system will start reducing certain features
of the vehicle that you may not be able to notice. At the
point that features are disabled, this message is displayed. It is used to convey that the vehicle is trying
to save the charge in the battery. Turn
off unnecessary
accessories to allow the battery to recharge.
ENGMET: Press this button to display information in
the English (miles) or metric (kilometers) system.

Downloaded from www.Manualslib.com manuals search engine BATTERY VOLTAGE HIGH - 8: This message shows
that the electrical charging system is overcharging (more
than 16 volts). To avoid being stranded, have the electrical
system checked by your dealership.
You can reduce the
charging overload by using the accessories.
Turn on the
lamps and radio, set the climate control on
AUTO and the
fan speed on

when the engine is running.
BATTERY VOLTAGE LOW - 6: This message will
appear when the electrical system is charging less than
9 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.

when they wear to a certain point. Have the front and
rear brakes serviced by your dealer as soon as possible.
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 “Brake
System Warning Light” 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.
CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and it should be changed
within
200 miles. See “Engine Oil” and “Filter
Recommendations” in the Maintenance Schedule
booklet. After
an oil change, the Oil Life Indicator must
be reset. See “Oil Life Indicator” in the Index
on how to
reset
it.

Downloaded from www.Manualslib.com manuals search engine 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.
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 "Engine Oil"
in the Index. The
system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the
vehicle has been driven
7,500 miles (12 500 km), it will
indicate to change the oil. If you drive
in a dusty area,
you should change your oil every
3,000 miles
(5 000 km) or three months (whichever comes first)
unless the display indicates changing it sooner.
When the oil is changed, you'll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFO button. Then press and hold the INFO RESET
button until the display shows
100% ENGINE
OIL LIFE.

any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.
of objects. This helps circulate air throughout
your vehicle.
0 Keep the air path under the front seats clear
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through
a passenger
compartment filter, which is part of
a three-piece filter
system. The filter removes certain contaminants from
the air, including pollen and dust particles. Reductions
in airflow, which
may occur more quickly in dusty
areas, indicate that the filter needs to be replaced early. The
carbon-treated filter is located inside the air
control module, with an access panel underneath the
instrument panel near the accelerator pedal. The
filter should be replaced as part of routine scheduled
maintenance. See the Maintenance Schedule booklet
for replacement intervals. See your dealer for details
on changing the filter.
Your vehicle will not be damaged if
you choose not to
replace the filter once the old one is removed. However,
the air will no longer be filtered.

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 adjustment.
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 “Engine Overheating’’
in the Index.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper Cadillac Service Manual. It tells
you much more about how to service your vehicle than
this manual can.
To order the proper service manual, see
“Service and Owner Publications” in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Vehicle” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Maintenance
Schedule Booklet.

Downloaded from www.Manualslib.com manuals search engine Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain. regularly reaches
90 OF (32 O C) or higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require change
until the message CHANGE
TRANS FLUID appears on
the Driver Information Center.
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done
at your Cadillac dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
1 NOTICE: - -1
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
