2002 CHEVROLET IMPALA reset

2-82 Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has been
driven in either miles (used in the United States) or in
kilometers (used in Canada).
Your vehicle has a tamper
-resistant odometer. If you see
ERROR, you'll know someone has probably tampered
with it and the numbers may not be accurate.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
But if it can't, then it will be set at zero and a label must
be put on the driver's door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
Your trip odometer tells how far you have driven since
you last reset it.
Your trip/select reset switch will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds.
If the button is pressed and held for longer than
1.5 seconds while in the trip odometer mode, it will
be reset to zero. If the button is pressed and held for
longer than 1.5 seconds while in the odometer mode,
it will have no effect.
Your trip odometer will work no matter what position
your key is in, and even if the key isn't in.

when you're driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you're driving, the anti
-lock brake system needs
service and you don't have anti
-lock brakes.

-lock brake system warning light should
come on briefly when you turn the ignition key to ON.
If the light doesn't come on then, have it fixed so it will
be ready to warn you if there is a problem.

The warning light should go off. See ªTraction
Control Systemº in the Index for more information.

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
