A computer system controls the engine's idle speed. When you
start your vehicle, the engine's idle speed normally runs high.
These faster engine speeds will make your vehicle coast 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.
*
[ST07390(ALL)07/95]
If the engine idle speed does not slow down automatically, do
not allow your vehicle to idle for more than 10 minutes. Have
the vehicle checked.
*
[ST07400(ALL)05/95]
RWARNING
Extended idling at high engine speeds can produce very
high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
*
[ST07450(ALL)05/95]
RWARNING
Do not park, idle, or drive your vehicle in dry grass or
other dry ground cover. The emission system heats up
the engine compartment and exhaust system, which can
start a fire.
*
[ST07500(ALL)03/95]
If you consistently start your vehicle in subzero temperatures,
use an engine block heater (if your vehicle has this option).

[ST07600(ALL)06/95]
Engine Block Heater (If equipped)
*
[ST07700(ALL)03/95]
Engine block heaters are strongly recommended if you live in a
region where temperatures reachs20ÊF (s29ÊC) orbelow
consistently during the winter months. An engine block heater
warms the engine coolant, which improves starting, warms up
the engine faster, and allows the heater-defrost system to
respond quickly.

Guarding Against Exhaust Fumes
*
[ST09400(ALL)02/95]
Carbon monoxide, although colorless and odorless, is present in
exhaust fumes. Take precautions to avoid its dangerous effects.
*
[ST09500(ALL)09/95]
RWARNING
Never let your vehicle idle in an enclosed area, and do
not sit in a parked vehicle, (with the engine running) for
more than a short period of time. Exhaust fumes,
particularly carbon monoxide, might build up. These
fumes are harmful and could kill you.
*
[ST09600(ALL)05/95]
RWARNING
If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not
drive if you smell exhaust fumes.

Check Engine Warning Light
*
[LG04600(ALL)05/95]
The Powertrain On-Board Diagnostic II (OBD II) system consists
of the hardware and software necessary to monitor the
operation of the powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain control system
during normal operation. If an emission problem is detected, the
Check Engine Warning Light (in the cluster) is turned on.
*
[LG04650(ALL)05/95]
Modification or additions to the vehicle may cause incorrect
operation of the OBD II system. Additions such as burglar
alarms, cellular phones, and CB radios must be carefully
installed. Do not install these devices by tapping into or running
wires close to powertrain control system wires or components.
[LG04675(ALL)02/95]
The light comes on briefly when you turn the ignition key to
the ON position, but it should turn off when the engine cranks.
If the light does not come on when you turn the ignition to the
ON position or if it comes on and stays on when you are
driving, have your vehicle serviced as soon as conveniently
possible. This indicates a possible problem with one of the
engine's emission control systems.You do not need to have
your vehicle towed in.
*
[LG04680(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.
*
[LG04685(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.
*
[LG04690(R )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

61 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.
*
[LG04695(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 have the engine serviced.
[LG04720(ALL)03/95]
Under certain conditions, the Check Engine Warning Light may
come on if the fuel cap is not properly installed. If the light
comes on and you suspect the fuel cap is not properly installed,
pull off the road as soon as it is safely possible and turn off the
engine. Remove and replace the fuel cap, making sure it is
properly seated.
[LG04750(ALL)03/95]
After completing the three consecutive warm-up cycles and on
the fourth engine start-up, the Check Engine Warning Light
should turn off. If the light does not go off after the fourth
engine restart, have your vehicle serviced by your dealer or a
qualified technician.
