To minimize the possibility of catalytic converter damage:
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 spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
NOTE: Your vehicle’s exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system, if the
exhaust system is replaced with aftermarket products a
Malfunction Indicator Lamp (MIL) will illuminate.
Cooling System
WARNING!
When working near the radiator cooling fan, discon-
nect the fan motor lead or place the ignition in the
LOCK position (OFF position for Keyless Enter-N-
Go). The fan is temperature controlled and can start
(Continued)
WARNING! (Continued)
at any time the ignition switch is in the ON position
(RUN position for Keyless Enter-N-Go).
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 try to open a cooling system pressure
cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every 12 months
(before the onset of freezing weather, where applicable). If
coolant is dirty or rusty in appearance, the system should be
drained, flushed, and refilled with fresh coolant. Check the
front of the radiator 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 coolant recovery bottle tubing for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the
bottle and radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP WHEN
THE COOLING SYSTEM IS HOT.
