STARTING PROCEDURE ENGINE
M
ANIFOLD AIR TEMPERATURE 0°F TO
66°F (–18°C
TO 19°C)
NOTE:
The temperature displayed in the instrument cluster does
not necessarily reflect the engine manifold air temperature
Ú
page 104. When engine temperatures fall below 66°F
(19°C) the Wait To Start Indicator Light will remain on indi-
cating the intake air heater system is active.
Follow the steps in the “Normal Starting” procedure
except:
1. The Wait To Start Indicator Light will remain on for a
period of time that varies depending on the engine
temperature.
2. While the Wait To Start Indicator Light is on, the
instrument cluster will additionally display a gauge or
bar whose initial length represents the full Wait To
Start time period. Its length will decrease until it
disappears when the Wait To Start time has elapsed.
3. After the Wait To Start Indicator Light goes off, place
the ignition switch in the START position. Do not press
the accelerator during starting.
4. After engine start-up, check that the Oil Pressure
Warning Light has turned off.
5. Release the parking brake and drive.
NOTE:
Engine idle speed will automatically increase to
1,000 RPM and engage the Variable Geometry Turbo-
charger at low coolant temperatures to improve engine
warm-up.
Automatic equipped vehicles with optional Keyless
Enter ‘n Go™ – If the start button is pushed once while
in PARK with the ignition off and driver’s foot on the
brake pedal, the vehicle will automatically crank and
start after the Wait to Start time has elapsed. If it is
desired to abort the start process before it completes,
the driver’s foot should be fully removed from the
brake pedal prior to pushing the start button again in
order for the ignition to move directly to off.
If the engine stalls, or if the ignition switch is left ON for
more than two minutes after the Wait To Start Indicator
Light goes out, reset the intake air heater by turning the
ignition switch to the OFF position for at least five
seconds and then back ON. Repeat steps 1 through 5
of “Starting Procedure – Engine Manifold Air Tempera-
ture 0°F To 66°F (–18°C to 19°C).”
