A computer system controls the engine's idle
speed. When you start your vehicle, the engine's
idle speed normally runs higher than when it's
warmed up. These faster engine speeds will
make your vehicle move slightly faster than its
normal idle speed. It should, however, slow
down after a short time. If it does not, have the
idle speed checked.

The light comes on briefly when you turn the
ignition key toON, but it should turn off when
the engine starts. If the light does not come on
when you turn the ignition toONor if it comes
on and stays on when you are driving, have
your vehicle serviced as soon as possible. This
indicates a possible problem with one of the
vehicle's emission control systems. You do not
need to have your vehicle towed in.
*
[LG11055( ALL)05/95]
If the light turns on and off at one (1) second
intervals while you are driving the vehicle, it
means that the engine is misfiring. If this
condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle
serviced at the first opportunity. You do not
need to have your vehicle towed in.
*
[LG11060( ALL)05/95]
If the light turns on and off on rare occasions
while you are driving, it means that a
malfunction occurred and the condition corrected
itself.
*
[LG11065( ALL)05/95]
An example of a condition which corrects itself
occurs when an engine running out of fuel
begins to misfire. In this case, the Check Engine
Warning Light may turn on and will then set a
Diagnostic Trouble Code indicating that the
engine was misfiring while the last of the fuel
was being consumed. After refueling, the Check
Engine Warning Light will turn off after the
vehicle has completed three consecutive warm
up cycles without a misfire condition occurring.
A warm up cycle consists of engine start from a
cold condition (engine at ambient temperature)
and running until the engine reaches normal
operating temperature.
*
[LG11075( ALL)05/95]
On the fourth engine start up, the Check Engine
Warning Light will turn off as soon as the
engine begins to crank. It is not necessary to

RWARNING
When parking, do not use the gearshift in
place of the parking brake. Turn the key
to LOCK whenever you leave your
vehicle. Always set the parking brake
fully and make sure that the gearshift is
securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual
transmission). Never leave your vehicle
unattended while it is running. If you do
not take these precautions, your vehicle
may move unexpectedly and injure
someone.
[DR13900(M )10/95]
To release the parking brake, pull the handle
upward, push in the button, then lower the
handle. The Brake System warning light will
glow if the parking brake is not fully released
when the engine is running.
*
[DR14200( ALL)03/95]
Always check the Brake Warning Light each
time you start your engine. Driving with the
parking brake on will cause the brakes to wear
out quickly and will reduce the fuel economy.
*
[DR14300( ALL)01/93]
RWARNING
If the parking brake is fully released, but
the Brake System light remains on, have
the brakes checked immediately. They
may not be working properly.
[DR14400( ALL)07/93]
The parking brake system is designed for static
parking only and is not designed to stop a
moving vehicle, but you can use the parking
brake to stop your vehicle in an emergency if
the normal brakes fail. However, since the
parking brake applies only the rear brakes, the
stopping distance will increase greatly and the
handling of your vehicle will be adversely
affected.
