ENGINE START/STOP Button Functions With
Driver’s Foot OFF The Brake Pedal (In PARK Or

The ENGINE START/STOP button operates

positions, OFF, ACC, RUN. To change the
ignition switch positions without starting the
vehicle and use the accessories follow these
steps:
1. Start with the ignition in the OFF position.
2. Push the ENGINE START/STOP button once
to change the ignition to the ACC position.
3. Push the ENGINE START/STOP button a
second time to change the ignition to the
RUN position.
4. Push the ENGINE START/STOP button a
third time to return the ignition to the OFF
position.
Keyless Enter-N-Go Starting Procedure —
Engine Manifold 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 111. When
engine temperatures fall below 66°F (19°C)
the “Wait To Start” telltale will remain on indi-
cating the intake air heater system is active.
Follow the steps in the “Normal Starting”
procedure except:
1. Pushing the ENGINE START/STOP button
with the driver’s foot on the brake will
move the ignition from OFF or ACC to RUN,
and will illuminate the “Wait To Start”
telltale. The engine will not immediately
crank, this is normal operation.
2. The “Wait To Start” telltale will remain on for
a period of time that varies depending on
the engine temperature.
3. While the “Wait to Start” telltale 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.
4. After the engine “Wait To Start” telltale goes
off, the engine will automatically crank.
5. After engine start-up, check to see that
there is oil pressure.
6. Release the parking brake and drive.
NOTE:
Engine idle speed will automatically increase
to 1,000 RPM and engage the Variable
Geometry Turbocharger at low coolant
temperatures to improve engine warm-up.
CAUTION!
If the “Water in Fuel Indicator Light” remains
on, DO NOT START the engine before you
drain the water from the fuel filters to avoid
engine damage Ú page 415.
CAUTION!
Do not crank the engine for more than
25 seconds at a time or starter motor dam-
age may result. Turn the ignition switch to the
OFF position and wait at least two minutes for
the starter to cool before repeating start pro-
cedure.
