Shift Indicator Light (Manual
Transmission Only)
This light will show you when to
shift to the next higher gear in
order to maintain better fuel
economy.
Be sure to consider the legal speed
limit, surrounding traffic speeds
and weather conditions when
shifting.
The light may flash when you
accelerate. This is normal.
Ignore this light when you down-
shift.
Also ignore this light if your vehicle
has four-wheel drive and the trans-
fer case is in four-wheel low.
Section 1
Traction Control System Light
This light should come on briefly
as you start the engine, as a check
to show you it is working properly.
If it doesn't come on, then have it
fixed so it will be ready to warn
you if there is a problem.
The light will flash when the
system is limiting wheel spin.
