Indicates vehicle speed.
2. Instrument Cluster Display
When the appropriate conditions exist,
this display shows instrument cluster
display messages Ú page 44.
Odometer/Trip Odometer Display Area
US Federal regulations require that upon
transfer of vehicle ownership, the seller
certify to the purchaser the correct mileage
that the vehicle has been driven. If your
odometer needs to be repaired or serviced,
the repair technician should leave the odom -
eter reading the same as it was before the
repair or service. If the technician cannot do
so, then the odometer must be set at zero,
and a sticker must be placed in the door
jamb stating what the mileage was before the
repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/service, so that you can be
sure that it is properly reset, or that the door
jamb sticker is accurate if the odometer must
be reset at zero.
Gear Selector Status (PRND)
The gear selector status “P,R,N,D,1,2,3,4,5,
6” are displayed indicating the gear selector
position. Telltales “1,2,3,4,5,6” indicate the
manual mode has been engaged and the
