If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes.
If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
SeeBrake System Warning Light on
page 5‑22.One-to-Four Shift Light
(Manual Transmission)
When this light comes on, the
vehicle can only be shifted from
1 (First) to 4 (Fourth) instead of
1 (First) to 2 (Second).
The shift must be completed into
4 (Fourth) to turn off this feature.
This helps the vehicle get the best
possible fuel economy.
After shifting to 4 (Fourth), the
vehicle can be downshifted to a
lower gear. Notice:
Forcing the shift lever
into any gear except 4 (Fourth)
when the 1 TO 4 SHIFT light
comes on may damage the
transmission. Shift only from
1 (First) to 4 (Fourth) when the
light comes on.
This light comes on when:
.The engine coolant temperature
is higher than 76°C (169°F).
.The vehicle is going 24 to
31 km/h (15 to 19 mph).
.The vehicle is at 21 percent
throttle or less.

When the Light Flashes First and
Then Is On Steady
This indicates that there may be a
problem with the TPMS. The light
flashes for about a minute and stays
on steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
SeeTire Pressure Monitor
Operation on page 10‑70 for
more information.Security Light
The security light should come on
briefly as the engine is started.
If the system is working normally,
the indicator light turns off. If it does
not come on, have the vehicle
serviced by your dealer.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system. This light is also used to indicate the
status of the anti-theft alarm system
when the ignition is turned off. The
light will flash rapidly if the alarm
system is arming and one or more
of the monitored entry points is not
closed. The light will stay on if the
alarm is arming and all entry points
are closed.

and the vehicle's security system,
