age, damage and loose electrical connections. Tighten
connections and if you discover any leakage or dam-
age, have it repaired immediately by a qualified tech-
nician.Road TestWhile driving the vehicle, check for proper operation
of engine, transmission, brakes and steering. Also
check for abnormal noise or vibration from any part
of the vehicle.Spark PlugsInstall new plugs of the same type as originally
equipped. Refer to your Owner’s Manual. A qualified
technician should perform this operation.Steering Linkage and BootsWith the vehicle stopped, check for excessive freeplay
