STARTING THE ENGINE
In normal circumstances, the engine should be
started from the driver’s seat. However, a rear-start
panel in the engine compartment allows starting the
engine from that location, typically for maintenance
operations. See "STARTING FROM THE ENGINE
COMPARTMENT" on the facing page
STARTING FROM THE DRIVER’S SEAT
l Make sure the engine STOP interlock button
located in the engine compartment is reset
(twist and pull) to enable starting from the
front and that the battery master switch
(master cut-out) located on the rear electrical
panel is set to the ON position;
TYPICAL ENGINE STOP/ IGNITION INTERLOCK BUTTON
MAIN ELECTRICAL SHUT-OFF SWITCH
l Apply the spring- loaded parking brake by
pulling the parking brake control button all the
way up;
l Place transmission in neutral;
l Turn ignition key to START position (refer to
"IGNITION SWITCH" on page5 in Controls
and Instruments chapter), release the key
after the engine starts;
NOTE
When the ignition is turned to ON, the M32QR
ABS Pressure Modulator Valve solenoids are
briefly energized. This can be audibly detected by
a rapid cycling of the PMVs. If the air system is
fully charged and the service brake pedal is
depressed when ignition is turned to ON, the
modulator valves create a sharp audible “chuff” of
air pressure.
l Brake pedal must be applied when selecting
Drive (D) otherwise the transmission will stay
in neutral (N);
CAUTION
Do not engage starter for more than 15 seconds at
a time. If engine does not start within 15 seconds,
release ignition key and let starter cool for one
minute before attempting to restart.
CAUTION
Do not press the accelerator pedal before starting.
This could result in an electronic control unit fault
and degrade the fuel system control.
CAUTION
Special precautions are necessary with
turbocharged engines to avoid possible turbine
damage. After starting, run the engine at normal
idle for two minutes to allow lubricating oil to reach
the turbocharger. Then run the engine at fast idle.
Let oil pressure reach normal operating range
before driving.
NOTE
If engine does not start, return key to OFF position
before attempting to restart.
