Normal Starting Procedure
Steps for starting the engine in normal
temperatures.
Allow the Wait-To-Start warning lamp to
turned off. Engine Wait-To-Start Lamp on
page 17
Follow this engine starting procedure when
the outside temperature is above 50°F
(10°C).
1. Ensure the parking brake is set ON
and the transmission shift lever is in
neutral. For automatic transmissions,
be sure the shift lever is in the neutral
position (N). For automatic
transmissions that have park (P)
position, place the shift lever in park.
2. With the accelerator pedal in the idle
position, turn the ignition key to the
START position to start the engine.
3. If the engine does not start after 10
seconds, release the key. Wait an
additional 10 seconds to allow the
starter motor to cool, then try staring
the engine again.
4. Once the engine has started, wait for
the oil pressure to rise, and the low
oil pressure warning lamp to turn off,
before increasing rpm.
After the engine is started, the voltmeter, if
equipped, may show a gauge fluctuation
under certain engine temperature
conditions (both warm and cold). This
cycling operation is caused by the post-
heat cycle of the intake manifold heater
system. The number of cycles and the
length of the cycling operation is controlled
by the engine control module. The cycling
action will cause temporary dimming of the
headlamps, interior lamps, and other
vehicle electrical accessories.
Cold Weather Starting
Steps for starting the engine in cold
temperatures.
Allow the Wait-to-Start warning lamp to
turn off. Engine Wait-To-Start Lamp on
page 17
Follow this engine starting procedure when
the outside temperature is below 50°F
(10°C).
