Safety Restraints for Children
*
[SR14400(BEF )02/95]
In the U.S. and Canada, you are required by law
to use safety restraints for children. If small
children ride in your vehicle Ð this generally
includes children who are four years old or
younger and who weigh 40 pounds (18 kg) or
less Ð you must put them in safety seats that
are made specially for children. Safety belts
alone do not provide maximum protection for
these children. Check your local and state laws
for specific requirements.
*
[SR14500(BEF )05/95]
RWARNING
Never let a passenger hold a child on his
or her lap while the vehicle is moving.
The passenger cannot protect the child
from injury in a collision.

[ST07300(BEF )05/95]
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.
*
[ST07350( ALL)05/95]
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(BEF )03/95]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[ST07600(BEF )03/95]
Engine Block Heater (If equipped)
(Standard in Canada)
*
[ST07700(BEF )03/95]
Engine block heaters are strongly recommended
if you live in a region where temperatures reach
-10ÊF (-23ÊC) orbelow. 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)05/95]
RWARNING
Do not start your vehicle in a closed
garage or other enclosed area. Never sit in
a stopped vehicle for more than a short
period of time with the engine running.
Exhaust fumes are toxic. SeeGuarding
Against Exhaust Fumesin this chapter for
more instructions.

vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you

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.

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.

[LG04600( ALL)05/95]
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.
*
[LG04625( 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.
*
[LG04650( 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.

NOTE: If your light truck is equipped with
dual fuel tanks, the ªCHECK ENGINEº
light may come on if fuel is restricted
to the engine or if the fuel flow is
momentarily disrupted because of an
empty fuel tank before you switched to
the auxiliary fuel tank. This condition
is normal and the light should go off
after full fuel flow is restored.
*
[LG04675( 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.
*
[LG04700( 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.
*
[LG04725( ALL)05/95]
Under certain conditions, the Check Engine
Warning Light may come on if the fuel cap is
not properly installed. If the Check Engine
Warning Light comes on and you suspect that
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.
