1. FUEL SYSTEM SPECIFICATION
Use Only Unleaded Fuel Rated at 89 Octane or Higher ▶
Fuel quality and additives contained in fuel have a significant effect on power output, drivability,
and life of theengine. Fuel with too low an octane number can cause engine knock.
- Use of fuel with an octane number lower than 89 may damage engine and exhaust system.
- To prevent accidental use of leaded fuel, the nozzles for leaded fuel are larger, and will not
fit the fuel filler neck of your vehicle.
Do Not Use Methanol ▶
Fuels containing methanol (wood alcohol) should not be used in vehicle.
This type of fuel can reduce vehicle performance and damage components of the fuel system.
- Use of methanol may damage the fuel sys-tem.
Vehicle Fueling from Drums or Storage Containers ▶
For safety reasons (particularly when using noncommercial fueling systems) fuel containers,
pumps and hoses must be properly earthed. Static electricity build up can occur under certain
atmospheric and fuel flow conditions if unearthed hoses, particularly plastic, are fitted to the
fuel-dispensing pump.
It is therefore recommended that earthed pumps with integrally earthed hoses be used, and
that storage containers be properly earthed during all noncommercial fueling operations.

1. OVERVIEW OF EXHAUST SYSTEM
When you are inspecting or replacing exhaust system components, make sure there is
adequate clearance from all points on the underbody to avoid possible overheating of the
floor panel and possible damage to the passenger compartment insulation and trim
materials.
Check the complete exhaust system and the nearby body areas and trunk lid for broken,
damaged, missing or mispositioned parts, open seams, holes, loose connections, or othe
r
deterioration which could permit exhaust fumes to seep into the trunk may be an indication
of a problem in one of these areas. Any defects should be corrected immediately. -
2. OVERVIEW OF MUFFLER
Aside from the exhaust manifold connection, the exhaust system uses a flange and seal joint
design rather than a slip joint coupling design with clamp and U-bolts.
If hole, open seams, or any deterioration is discovered upon inspection of the front muffler and
pipe assembly, the complete assembly should be replace, the complete assembly should be
replaced.
The same procedure is applicable to the rear muffler assembly. Heat shields for the front and
rear muffler assembly and catalytic converter protect the vehicle and the environment from the
high temperatures that the exhaust system develops.
3. OVERVIEW OF CATALYTIC CONVERTER
When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do
not contact the catalytic converter, as this could damage the catalytic converter. -
Use of anything other than unleaded fuel will damage the catalyst in the catalytic
converter. -
The catalytic converter are emission-control devices added to the exhaust system to
reduce pollutants from the exhaust pipes.
The oxidation catalyst is coated with a catalytic material containing platinum and
palladium, which reduces levels of hydrocarbon (HC) and carbon monoxide (CO) from
the exhaust gas. The three-way catalyst has coatings which contain platinum and
rhodium, which additionally lower the levels of oxides of nitrogen (NOx). ·
