To minimize the possibility of catalytic converter dam-
age:
• Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any ignition coil connec-
tors disconnected for prolonged periods.

very rough idle or malfunctioning operating condi-
tions.

Cooling System
WARNING!
• You or others can be badly burned by hot coolant
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 try to open a cooling system pressure cap
when the radiator is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed, and refilled with fresh coolant. Check the front
of the A/C condenser (if equipped) or radiator for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
