Speedometer And Odometer; Tachometer - GMC SIERRA 1998 Manual

Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mphj and kilometers per hour (km/hj. Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
Tamper-Resistant Odometer
Your odometer is tamper-resistant. The odometer will
show silver lines between the numbers if someone tries
to turn it back.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new odometer can be set
to the mileage total of the old odometer, then it must be.
But if it can't, then it's 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
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
To reset the trip odometer, fully press the reset button
located near the trip odometer readout. If the reset
button is not fully pressed, the trip odometer may not go
all the way back to zero. If it doesn't, you may have to
press the reset button again to reset the readout to zero.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpmj.
NOTICE:
On vehicles with a manual transmission, if you
operate the engine with the tachometer in the red
area, your engine or other parts could be damaged.
Damage to your engine or vehicle caused by
operating the engine in the red area isn't covered
by your vehicle warranty. Don't operate the
