DIC Warnings and Messages
These messages will appear if there is a problem
sensed in one of your vehicle’s systems. Vehicles that
are rst sold in Canada will have a number after
each message. This number helps to identify the
problem. You must then press INFO or INFO RESET to
clear the display screen for further use. However, be
sure to take any message that appears on the display
screen seriously and remember that pressing the
INFO or INFO RESET button will only make the
message disappear, not the problem.
DIC messages can also be displayed in French,
German, Spanish and Japanese. Contact your dealer to
have the language display adjusted for your vehicle.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 means that the vehicle is trying to save
the charge in the battery. Turn off unnecessary
accessories to allow the battery to recharge.
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 HI, and
turn the rear window defogger on. You can monitor
battery voltage on the DIC by pressing the INFO button.
The normal range is 11.5 to 15.5 volts when the
engine is running.
3-65

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 nal 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. SeeScheduled
Maintenance on page 6-4. After an oil change, the Oil
Life Indicator must be reset. SeeOil Life Indicator
on page 3-89. SeeEngine Oil on page 5-15.CHANGE TRANS FLUID – 47:This message will
appear when it is time to change the transaxle uid. See
Scheduled Maintenance on page 6-4for the proper
uid and change intervals.
CHECK BRAKE FLUID – 37:This message will display
if the ignition is in ON to inform the driver that the brake
uid level is low. Have the brake system serviced by a
technician as soon as possible. SeeBrake System
Warning and Parking Brake Indicator Light on page 3-51.

appear when there is a low level of engine coolant. Have
the cooling system serviced by a technician as soon
as possible. SeeEngine Coolant on page 5-27.
CHECK FUEL GAGE – 50:(Analog Cluster) 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.

Your radio can store home and away presets. Home and
away presets allow you to use one set of preset radio
settings in the area where you live, and another set when
you go out of town. You will not need to reprogram the
presets every time you travel. With the radio off and the
time displayed, use fast forward and reverse to select
home or away presets. To select the away presets, press
and hold FF for ve seconds until you hear a beep. The
next time the radio comes on, the away presets will be
active. To select the home presets, press and hold RW
for ve seconds until you hear a beep. The next time the
radio comes on, the home presets will be active.
When battery power is removed and later applied, you
will not have to reset the home radio presets because
the radio remembers them. However, you will have
to reset the away radio presets.Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identication Number
(VIN). If the radio is moved to a different vehicle, it
will not operate. If the radio is removed from your
vehicle, the original VIN in the radio can be used to
trace the radio back to your vehicle.
With THEFTLOCK
®activated, the radio will not operate
if stolen.

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO XM SIGNAL to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
is an increased level of static while listening to the
radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Weather Band
Weather band is restricted to speech and the audio
quality is not as good as with the AM or FM bands.
Depending on location, the radio should receive one or
two channels.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat. If they are not, they may not operate
properly or may cause failure of the tape player.
The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLEAN TAPE to
indicate that the tape player has been used for 50 hours
without resetting the tape clean timer. If this message
appears on the display, the cassette tape player needs to
be cleaned. It will still play tapes, but it should be cleaned
as soon as possible to prevent damage to the tapes and
player. If there is a reduction in sound quality, try a known
good cassette to see if the tape or the tape player is at
fault. If this other cassette has no improvement in sound
quality, clean the tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer.

Here are some things to do to summon help and keep
yourself and your passengers safe:
Turn on your hazard ashers.
Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can not see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
