STARTING AND OPERATING THE VEHICLE<br />
TO START” indicator lamp turns ON, wait until the<br />
indicator lamp goes OFF (approximately 60 seconds)<br />
before attempting to start the engine. (For each<br />
engine and ambient temperatures, warm-up cycles<br />
will vary.)<br />
7. Turn the ignition switch to the IGN & START position<br />
to engage the starter. Crank the engine until it starts.<br />
If the engine does not start within 30 seconds, release<br />
the key.<br />
Use of Accelerator<br />
• For mild to warm temperatures above 60°F (16°C)<br />
keep your foot OFF the accelerator pedal while cranking.<br />
If the engine does not start after 5 seconds, apply<br />
full throttle while cranking.<br />
• For below normal starting temperatures fully depress<br />
the accelerator (throttle) pedal after engaging the<br />
starter.<br />
NOTE: Pumping the accelerator will not assist in<br />
starting the engine.<br />
CAUTION: To help avoid overtaxing the starter<br />
motor or batteries, or causing engine damage,<br />
follow the recommendations listed below:<br />
• Do not engage starter for more than 30 seconds at a<br />
time.<br />
• Wait two minutes between each attempt to start the<br />
engine. This allows the starter motor to cool and time<br />
for the batteries to regain power.<br />
• If the engine fails to start after a couple of tries, there<br />
could be a malfunction with the engine or other<br />
related system. Make any adjustments or repairs necessary<br />
before trying to start the engine again.<br />
When the engine starts:<br />
• Watch the oil pressure gauge. Oil pressure should<br />
rise within 15 seconds after the engine starts. If the oil<br />
pressure does not rise, stop the engine. Find what is<br />
wrong before restarting. Check the Engine Operation<br />
and Maintenance <strong>Manual</strong> for the right oil pressure for<br />
your vehicle's engine. In most engines, idle pressure<br />
should be about 15 psi.<br />
