6-4 Starting and Stopping Procedures
DOB 1300-1556 PA-1639 Operator's Manual 2020 X3-45 Commuter
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
1. 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 main electrical shut- off
switch is set to the ON position;

2. Make sure that the parking brake is applied.
If not, apply the parking brake by pulling the
parking brake control button all the way up;
3. With the foot off the accelerator pedal, turn
the ignition switch to the ON position and
momentary push the START push button to
crank the engine;
NOTE
An electronic protection will prevent the engine
from starting if the parking brake is not applied.
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.
4. 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 the bush button and
let starter cool for one minute before attempting
to restart.
NOTE
If engine does not start, return the switch to
OFF position 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 the accelerator pedal is depressed before
starting, release and wait 30 seconds before
attempting to restart.
