CAUTION: Anti-freeze content must never be allowed to fall below 25% otherwise damage to the
engine is liable to occur. Also, anti-freeze content should not exceed 60% as this will greatly
reduce the cooling effect of the coolant.
FUEL REQUIREMENTS
Catalyst vehicles
Vehicles equipped with catalytic converter are designed to use ONLY unleaded fuel. Unleaded fuel must be used
for the emission control system to operate properly. Its use will also reduce spark plug fouling, exhaust system
corrosion and engine oil deterioration.
Using fuel that contains lead will result in damage to the emission control system and could result in loss of
warranty coverage. The effectiveness of the catalysts in the catalytic converters will be seriously impaired if leaded
fuel is used. The vehicle is equipped with an electronic fuel injection system, which includes two oxygen sensors.
Leaded fuel will damage the sensors, and will deteriorate the emission control system.
Regulations require that pumps delivering unleaded fuel be labelledUNLEADED.Only these pumps have nozzles
which fit the filler neck of the vehicle fuel tank.
