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 engine coolant heater cord is located on
the passenger's side of the vehicle, above the
headlamp assembly.
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.

2-76 Oil Pressure Light
If you have a problem
with your oil, this light
may stay on after you start
your engine, or come on
when you are driving.
A warning chime and the DIC message LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be low
on oil, or could have some other oil problem. Have it
fixed right away.
The oil light could also come on briefly when the
ignition is on but the engine is not running. The light
will come on as a test to show you it is working, but
the light will go out about five seconds after you turn
the ignition to START. If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.CAUTION:
Don't keep driving if the oil pressure is low. If you
do, your engine can become so hot that it catches
fire. You or others could be burned. Check your oil
as soon as possible and have your vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems
can be costly and is not covered by your warranty.

Driver Information Center (DIC)
The Driver Information Center (DIC) displays
information in either English or metric. When the
system is on or off, push the ON/OFF button down
for three seconds to change the display between English
and metric. This will also change the digital screen for
the climate control system between English and metric.The DIC has different display modes which can be
accessed by pressing the four buttons on the DIC.
These buttons are labeled ON/OFF, SELECT right
arrow, SELECT down arrow and RESET. The button
functions are detailed in the following.
Turn on the system by pressing the ON/OFF button
once. When you turn on the ignition, the DIC will be in
the mode last displayed when the engine was turned off.
Keep in mind that this also applies to the OFF mode.
To turn off messages on the DIC (except LOW OIL
PRESSURE, LOW BRAKE FLUID, PARK BRAKE
SET, STARTING DISABLED and the HOT...STOP
ENGINE warning), press the RESET button.
Pressing the SELECT right arrow button will allow
you to access the following modes, DATE/ET, FUEL,
ECON, OIL and GAGE. While in any of these modes,
warning messages can interrupt and take over the
display until you acknowledge the message, or the
condition causing the problem goes away.

2-81 Oil Life
The GM Oil Life System is the only function
accessible in the OIL mode. Engine oil life is displayed
in a reading such as:
OIL LIFE 30%
This is an estimate of the oil's remaining useful life.
It will show 100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the system will
alert you with this message:
CHANGE OIL SOON
When the oil life is down to zero, you will receive
this message:
CHANGE OIL NOW
Always reset the OIL LIFE reminder after an oil change.
To reset the Oil Life System, see ªOil Life Systemº in
the Index. Also, see ªEngine Oil, When to Changeº in
the Index.Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It can't be reset accurately until the next oil change.
The DIC does not replace the need to maintain your
vehicle as recommended in the Maintenance Schedule
in this manual. Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil. If you drive in dusty areas, change your
oil after every 3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you to
do so sooner. Also, the oil change reminder does not
measure how much oil you have in your engine. So,
be sure to check your oil level often. See ªEngine Oilº
in the Index.
