STARTING PROCEDURE — COLD TEMPERATURES<br />
CAUTION: Do not try to put the vehicle in<br />
motion before pressure in the air system<br />
reaches 100 psi (689 kPa) because the wheels<br />
will still be locked by the spring brake action.<br />
• Unnecessary stress and possible brake<br />
malfunction could occur if the vehicle is<br />
forced to move before the air system<br />
reaches 100 psi (689 kPa).<br />
Starting Procedure — Cold Temperatures<br />
In addition to the previous “Normal Starting Procedures,”<br />
use these Cold Weather Starting guidelines when the air<br />
temperature falls below a certain temperature. Check<br />
your Engine Operation and Maintenance <strong>Manual</strong> for further<br />
details on when cold weather starting aids are<br />
needed.<br />
Using special cold-starting equipment will help the engine<br />
start easier. And in cold weather, fast engine starting<br />
helps relieve the loads on the electrical system and cranking<br />
motor. If you follow these few simple guidelines, you<br />
will extend the service life of your vehicle's engine:<br />
STARTING AND OPERATING THE VEHICLE<br />
• Keep the electrical system in top condition.<br />
• Use the best quality and recommended grade of fuel<br />
(see Engine Operation and Maintenance <strong>Manual</strong>).<br />
• Use the recommended engine lubricating oil.<br />
• As stated in the Normal Starting Procedures, when<br />
temperatures are below normal, fully depress the<br />
accelerator pedal after engaging the starter.<br />
Engine Block Heater (Option)<br />
To preheat the engine before starting, plug the optional<br />
engine block heater into a properly grounded AC electrical<br />
source. Do not start the engine with the heater plugged in.<br />
WARNING! Engine block heaters can cause<br />
fires resulting in death or serious personal<br />
injury and/or property damage if not properly<br />
maintained and operated. Regularly inspect<br />
the engine block heater wiring and connector<br />
for damaged or frayed wires. Do not use the<br />
heater if there are any signs of problems. Contact<br />
your Authorized Service Center or the<br />
manufacturer of the heater if you are in need<br />
of repairs or information.<br />
