Use the hazard warning flasher to warn other drivers any time your vehicle becomes a traffic hazard. day or night. Avoid stopping on the roadway if possible, To turn it on. push the button (inside the collar) beneath the steering
wheelan the right of the steering column. The flasher should work with the
ignition either off or on .
The turn
signals do not work when the hazard flasher is on. On some vehicles. if the brake pedal is pushed down. the lights will not flash until the brake is
released. To turn off the flasher. pull the button collar out.
EMERGENCY STARTING YOUR VEHICI.E .DUE TO A
DISCHARGED BATTERY
H your vehicle will not start rue to a discharged battery. it can often be started
by using energy from another battery -a procedure called "jump starting."
NOnCE: Do not push or tow thl' vehicle to start It. Under some conditions this may damage the catalytlc ·converter or other parts of the vehicle. Alao, 'since this vehicle ,has a 12 volt bettery, be sure the vehlc .. or equiprnetlt used to jump start your engine Is also 12 volt.

Make sure the water pu"",, belts are not broken, or off the pulleys , and that the fan runs when the engine is running and there is an indication on the instrument panel of an overheat condition.
If the coolant level in the recovery tank is low, look for leaks at the radiator
hoses and connections, heater hoses and connections, radiator I and water pump. If you find major leaks, or spot other problems that may have caused
the engine to overheat,
do not run the engine untilthese problems have been
corrected. If you do not find a leak or other problem, caretully add coolant to
the recovery tank. (Coolant is a mixture of ethylene glycol antifreeze and water; see "Engine Cooling System" in "'Service and Maintenance," Section 5, for the proper antifreeze and mixture.) .
CAUTION: Under: some:' conditione, the ethylen~ glycol In engine coolant Is . combustible. -To help avoid being burned, DO NOT spill antifreeze or coolant on the exhauat system or hot engine parts..
If the coolant level in the recovery tank is at the correct level but there is still
an indication on the instrument panel of an overheat condition:
•
You may add coolant directly to the radiator. YOU MUST LET ENGINE COOL FIRST. See "Coolant Replacement" under "Engine Cooling
System"
in Section 5, "Service and Maintenance" in this manual. Follow steps t through 3 for the correct way to remove the radiator
cap
and add coolant.
Once the Engine Coolant Temperature light has gone out (or the Engine Coolant Temperature gage no longer signals an overheat condition), you can
resume
driving at a reduced speed. Return to normal driving after about ten
minutes If the light does not come back on (or the gage pointer does not again

tf no cause for the overheat condition was found, see a qualified service technician.
JACKING
CAUTION
To help avoid personal injury:
• FollOW all jacking and stowage instructions .
• Use jack only for lifting this vehicle during wheel change.
• Never get beneath the vehicle, start or run engine while vehicle is
supported by jack.
• Always securely restow spare tire (or flat tire) and all jacking equipment.

Downloaded from www.Manualslib.com manuals search engine NOTICE: H you need to replace the fuel cap, use only a cap specified for your model. An incorrect fuel cap can result in a serious maHunction of the fuel system or emission control system. You can get a correct replacement cap from your dealer.
CATALYTIC CONVERTER
The catalytic converter is an emission control device added to the exhaust system to reduce exhaust gas pollutants. The converter contains
a ceramic material coated with noble metal catalysts. To prevent contamination
and loss of effectiveness of the catalysts. unleaded gasoline must be used.
Unleaded
gasoline also reduces spark plug fouling, exhaust system corrosion and engine oil deterioration. Leaded gasoline will also damage the oxygen
sensor
in the Computer Command Control system which could affect emission
control.
To help prevent damage:
1. Keep your engine properly maintained. Engine malfunctions involving the
electrical, carburetion, electronic fuel injection or ignition systems may
result in unusually high catalytic converter and exhaust system
temperatures which, under extreme malfunctioning conditions, may ignite
interior floor ·covering materials above the converter. Do not keep driving
your vehicle if you detect engine misfire, noticeable loss of
performance, or other unusual operating conditions. Instead, have it
serviced promptly. See the Maintenance Schedule folder for information on inspecting and maintaining the engine, exhaust system, and other
components.
2. Do not push or tow this vehicle to start it. This may result in unusually
high catalytic converter
and exhaust system temperatures which under
extreme conditions may ignite interior floor-covering material above the
converter.
Disregarding these instructions
could damage the catalytic converter, the vehicle, or nearby property and affect warranty coverage.
COMPUTER COMMAND CONTROL SYSTEM
Most vehicles sold in the United States (and some vehicles sold in Canada)
have the Computer Command Control system.
The Computer Command Control system monitors the exhaust stream with
an oxygen sensor. Based on sensor signals, the electronic control module adjusts
the air-fuel ratio
as needed. It is very important to use only unleaded
gasoline in vehicles equipped with the Computer Command Control system.
Leaded gasoline will damage the oxygen sensor,
and may affect emission
control.
"Check Engine" Light
Most vehicles sold in the United States (and some vehicles sold in Canada)
have the Computer Command Control system.
Vehicles
.with the Computer Command Control system, include a "CHECK
ENGINE" light
on the instrument panel designed to indicate the need for
system service. It will come on during engine starting to let you know the bulb
is working. (The
light will stay on a short time aiter the engine starts.) Have the
system repaired if the "CHECK ENGINE" light does not come on during engine
starting.
If the light comes on, either intermittently or continuously while driving,
service to the Computer Command Control system is required. Although in

case. To check, remove the dipstick on the driver's side of the case, above the
axle shaft, Be sure that the fluid level is at the "Full Cold" mark; oil may
appear on the bottom of the dipstick even when the fluid is several pints low.
I! needed, add enough lubricant to bring the fluid level up to the "Full Cold" mark on the dipstick. Be sure to fully seat the dipstick when reinstalling.
CLUTCH ADJUSTMENT
The clutch linkage in your vehicle should be adjusted every 5,000 miles (8 000
km) or less. To adjust the clutch linkage pull the clutch pedal up until it stops
and then depress the
pedal slowly.
NOTICE: To avoid clutch linkage damage do not continue to pull up on the pedal after
it stops.
Electric Fan
CAUTION: Keep hands, tools, and clothing away fr,om th~engine cooUng lanto help prevent personal injury. this fan is electric and can corne on whether or not the engine is
running. The fan can start automatically in response to a heat sensor when the ignition
key is in the "Run" position.
ENGINE COOLING SYSTEM
CAUTION: H your cooling system overheats, see "Engine Cooling System Overheating" in "In Case of Emergency," Section 3. CONTINUED OPERATION OFTHE ENGINE EVEN FOR A SHORT TIME MAY RESULT IN A FIRE AND THE POSSIBILITY OF
PERSONAL INJURY ANDIOR SEVERE VEHICLE DAMAGE.
Your vehicle has a coolant recovery.system. Coolant in the system expands with heat and overflows into the recovery tank. When the system cools down,
coolant is drawn back into the radiator.
