HECKING

EVEL

To ensure proper engine lubrication, the engine oil

must be maintained at the correct level. Check the

oil level at regular intervals, such as every fuel

stop. The best time to check the engine oil level is

about five minutes after a fully warmed up engine

is shut off.
Checking the oil while the vehicle is on level ground

will improve the accuracy of the oil level readings.
There are four possible dipstick types:



Crosshatched zone.



Crosshatched zone marked SAFE.



Crosshatched zone marked with MIN at the low

end of the range and MAX at the high end of the

range.



Crosshatched zone marked with dimples at the

MIN and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch

markings on the dipstick.
Adding 1 quart (1 liter) of oil when the reading is at

the low end of the dipstick range will raise the oil

level to the high end of the range marking.

DDING

ASHER

LUID

The windshield and rear window washers share the

same fluid reservoir. The fluid reservoir is located

in the front of the engine compartment. Be sure to

check the fluid level in the reservoir at regular

intervals. Fill the reservoir with windshield washer

solvent (not radiator antifreeze) and operate the

system for a few seconds to flush out the residual

water.
When refilling the washer fluid reservoir, take

some washer fluid and apply it to a cloth or towel

and wipe clean the wiper blades, this will help

blade performance.
To prevent freeze-up of your windshield washer

system in cold weather, select a solution or mixture

that meets or exceeds the temperature range of

your climate. This rating information can be found

on most washer fluid containers.

The best protection against carbon monoxide entry

into the vehicle body is a properly maintained

engine exhaust system.
If you notice a change in the sound of the exhaust

system; or if the exhaust fumes can be detected

inside the vehicle; or when the underside or rear of

the vehicle is damaged; have an authorized

technician inspect the complete exhaust system

and adjacent body areas for broken, damaged,

deteriorated, or mispositioned parts. Open seams

or loose connections could permit exhaust fumes

to seep into the passenger compartment. In

addition, have the exhaust system inspected each

time the vehicle is raised for lubrication or oil

change. Replace as required.

2 — Wiper Blade Pivot Pin
3 — Wiper Arm Receptacle
4 — Wiper Arm

WARNING!



Exhaust gases can injure or kill. They contain

carbon monoxide (CO), which is colorless and

odorless. Breathing it can make you uncon

scious and can eventually poison you. To

avoid breathing CO see

page 221.



A hot exhaust system can start a fire if you

park over materials that can burn. Such mate

rials might be grass or leaves coming into

contact with your exhaust system. Do not park

or operate your vehicle in areas where your

exhaust system can contact anything that can

burn.

CAUTION!



The catalytic converter requires the use of

unleaded fuel only. Leaded gasoline will

destroy the effectiveness of the catalyst as an

emissions control device and may seriously

reduce engine performance and cause

serious damage to the engine.

264

SERVICING AND MAINTENANCE

(Continued)

Under normal operating conditions, the catalytic

converter will not require maintenance. However, it

is important to keep the engine properly tuned to

ensure proper catalyst operation and prevent

possible catalyst damage.

NOTE:

Intentional tampering with emissions control

systems can result in civil penalties being

assessed against you.
In unusual situations involving grossly

malfunctioning engine operation, a scorching odor

may suggest severe and abnormal catalyst

overheating. If this occurs, stop the vehicle, turn off

the engine and allow it to cool. Service, including a

tune-up to manufacturer's specifications, should

be obtained immediately.

To minimize the possibility of catalytic converter

damage:



Do not interrupt the ignition when the transmis

sion is in gear and the vehicle is in motion.



Do not try to start the vehicle by pushing or

towing the vehicle.



Do not idle the engine with any ignition compo

nents disconnected or removed, such as when

diagnostic testing, or for prolonged periods

during very rough idle or malfunctioning oper

ating conditions.

OOLING

YSTEM

Engine Coolant Checks

Check the engine coolant (antifreeze) protection

every 12 months (before the onset of freezing

weather, where applicable). If the engine coolant is

dirty, the system should be drained, flushed, and

refilled with fresh Organic Additive Technology

(OAT) coolant (conforming to MS.90032) by an

authorized dealer. Check the front of the A/C

condenser for any accumulation of bugs, leaves,

etc. If dirty, clean by gently spraying water from a

garden hose vertically down the face of the

condenser.
Check the engine cooling system hoses for brittle

rubber, cracking, tears, cuts, and tightness of the

connection at the coolant recovery bottle and

radiator. Inspect the entire system for leaks. DO

NOT REMOVE THE COOLANT PRESSURE CAP

WHEN THE COOLING SYSTEM IS HOT.



Damage to the catalytic converter can result if

your vehicle is not kept in proper operating

condition. In the event of engine malfunction,

particularly involving engine misfire or other

apparent loss of performance, have your

vehicle serviced promptly. Continued opera

tion of your vehicle with a severe malfunction

could cause the converter to overheat,

resulting in possible damage to the converter

and vehicle.

CAUTION!

WARNING!



You or others can be badly burned by hot

engine coolant (antifreeze) or steam from your

radiator. If you see or hear steam coming from

under the hood, do not open the hood until the

radiator has had time to cool. Never open a

cooling system pressure cap when the radi

ator or coolant bottle is hot.



Keep hands, tools, clothing, and jewelry away

from the radiator cooling fan when the hood is

raised. The fan starts automatically and may

start at any time, whether the engine is

running or not.



When working near the radiator cooling fan,

disconnect the fan motor lead or turn the igni

tion to the OFF mode. The fan is temperature

controlled and can start at any time the igni

tion is in the ON mode.
