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 kilometers (used in Canada).
Your vehicle has a tamper-resistant odometer. You may
wonder what happens if your vehicle needs a new
odometer installed. If possible, the new one has to be
set to the same reading the old one had. If it can’t
be, then it’s set at zero and a label must be put on the
driver’s door to show the old mileage reading and
when the new odometer was installed.
Trip Odometer
A trip odometer can tell how far you’ve driven since you
last set it back to zero. To reset it, push the RESET
button. The trip odometer is reset through the Driver
Information Center (DIC) if your vehicle is equipped
with this feature. SeeDIC Controls and Displays
on page 3-47for more information.
Tachometer
The tachometer tells you
how fast the engine is
running. It displays
engine speed in
thousands of revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
