Extreme Cold Weather (Below –20°F Or −29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than -31°F (-35° C)
and the oil temperature sensor reading indicates an
engine block heater has not been used. The message
“plug in engine heater” will be displayed in the instru-
ment cluster when the ambient temperature is below
-25°F (-32° C) at the time the engine is shut off as a
reminder.
Extended Park Starting
NOTE:
Extended Park condition occurs when the vehicle
has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery
to ensure a full battery charge during the crank cycle.
2. Cycle the ignition in the START position and release it
when the engine starts.
3. If the engine fails to start within ten seconds, cycle the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow
the starter to cool for at least 10 minutes, then repeat
the procedure.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
