PART 7: STARTING & OPERATING THE VEHICLE<br />
Since each vehicle is custom-equipped, all engine operation<br />
instructions in this manual are general. You will want<br />
to consult the manual for your engine to find out details<br />
about your specific engine’s needs. You may need to use<br />
a slightly different procedure from the one outlined here.<br />
Also check the ATA Truck Driver’s Handbook provided with<br />
your vehicle. It will give you tips on starting, shifting, and<br />
driving a truck.<br />
Below are instructions for both normal-temperature starting<br />
and cold-weather starting.<br />
Normal Temperature Starting Procedure<br />
When the outside temperature is above 50° F (10° C), you<br />
can use the following procedure.<br />
1. Set the parking brake.<br />
2. Put your main transmission in Neutral.<br />
3. Disengage (depress) the clutch (with manual transmission).<br />
4. Turn the key switch to ON. The vehicle’s system will<br />
conduct a test of all gauges and warning lights.<br />
NOTE: If the instrument panel displays other<br />
messages or if other alarms activate <strong>after</strong> the<br />
key is turned ON, see the Instruments and Controls<br />
section to understand what you should do.<br />
CAUTION: Never operate the starter motor<br />
while the engine is running. The starter and<br />
flywheel gears could clash or jam, severely<br />
damaging them.<br />
NOTE: Some starters are equipped with overcrank<br />
protection. Check the “Engine Operation<br />
and Maintenance <strong>Manual</strong>” for details.<br />
5. Turn the ignition key to the START position. If the<br />
engine does not start within 30 seconds, release the<br />
starter button. To avoid overtaxing the starter motor<br />
or the batteries, don’t use the starter for more than 30<br />
seconds. Let the starter motor cool and the batteries<br />
recover for two minutes before trying again.<br />
