2001 CHEVROLET BLAZER ignition

2-65
Turn the display on or off by pressing the ON/OFF
button. Display the temperature in either degrees
Fahrenheit (English) or Celsius (metric) by pressing
the US/MET button.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on.
If the outside temperature is 37
F (3
C) or lower
when you turn on the ignition, ªICEº will appear
on the display. This is a warning to the driver that road
conditions may be icy, and that appropriate precautions
should be taken.
The compass is self
-calibrating, so it does not need to
be manually set. However, when your vehicle is new,
the compass may function erratically. If it does, ªCALº
(Calibration) will appear on the display. To correct the
problem, drive in a complete 360 degree circle three
times, and the compass will function normally.Variance is the difference between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to
set the variance for your particular location:
1. Find your location on the zone map. Record your
zone number.
2. Press and hold both the ON/OFF and the US/MET
buttons. The display will go off.

2-66
3. After five seconds, VAR CAL will appear on the
display. When it does, release both buttons.
4. Press US/MET until your zone number appears
on the display.
5. Press ON/OFF to enter your zone number.
Your variance is now set.
Driver Information System (If Equipped)
This system displays the outside air temperature,
compass direction and trip information in the
overhead console.
US/MET: The US/MET (United States/metric) button
allows you to switch the display between the English
and metric system.
MODE: The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.COMP/TEMP: The display provides the outside
temperature and one of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move the
vehicle, the temperature indicated will be the last
outside temperature recorded with the ignition on.
If the outside temperature is 37
F (3
C) or lower,
the display will toggle between the word ªICEº and
the current temperature every eight seconds. This is a
warning to the driver that road conditions may be icy,
and that appropriate precautions should be taken.
The compass is self
-calibrating, so it does not need
to be manually set. However, if ªCº (Calibration) is
displayed, the compass will need to be calibrated.
You may also place the compass in a noncalibrated
mode by pressing and holding the MODE and US/MET
buttons simultaneously while in the COMP/TEMP
mode. After about 10 seconds, the compass will display
ªCº and you can release the buttons. Drive the vehicle
in a complete 360 degree circle three times at a speed of
less than 5 mph (8 km/h), and the compass will function
normally. Once the calibration is complete, the display
will return to a compass reading.

Sunroof (If Equipped)
Your vehicle may be equipped with a power sliding sunroof.
To open or close your sunroof, the ignition needs to be in
RUN or ACCESSORY or Retained Accessory Power
(RAP) needs to be active. See ªRetained Accessory Powerº
in the Index.
Press and release the rear side of the button in the mini
console to open the sunroof. You can press the forward side of the button to close
the sunroof. Once the sunroof is closed, press the
forward side of the button to open the sunroof to the
vent position.
The sunroof is also equipped with a sunshade which you
can pull forward to block sun rays.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the
air bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, see ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so
it will be ready to warn you if there is a problem.

Charging System Indicator Light
The charging system light
will come on briefly when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. It could indicate
that you have problems with a generator drive belt, or
another electrical problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition
is on (in RUN), this gage
shows your battery's state
of charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between
the low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.

2-92
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Shift Light
You have the shift light
on the instrument panel
cluster if you have a
manual transmission.
Shifting when the indicator light is on will help you get
the best fuel economy. See ªShift Lightº in the Index.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on if your parking brake doesn't release fully.
If it stays on after your parking brake is fully released,
it means you have a brake problem.
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.

2-93
This light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then,
have it fixed so it will be ready to warn you if there's
a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will
come on when you start
your engine and may stay
on for several seconds.
That's normal.
If the light stays on, or comes on when you're driving,
your vehicle needs service. If the regular brake system
warning light isn't on, you still have brakes, but you
don't have anti
-lock brakes. If the regular brake system
warning light is also on, you don't have anti
-lock
brakes and there's a problem with your regular brakes.
See ªBrake System Warning Lightº earlier in
this section.
The anti
-lock brake system warning light should
come on briefly when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so it will
be ready to warn you if there is a problem.

Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index for
more information.
Malfunction Indicator Lamp
(Service Engine Soon Light in the United
States or Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner environment.
The SERVICE ENGINE SOON or CHECK ENGINE
light comes on to indicate that there is a problem and
service is required. Malfunctions often will be indicated
by the system before any problem is apparent. This may
prevent more serious damage to your vehicle. This system
is also designed to assist your service technician in correctly
diagnosing any malfunction.
