STARTING PROCEDURE — COLD TEMPERATURES STARTING AND OPERATING THE VEHICLE
– 90 – Y53-6033
Regional Haul (R05/10)
CAUTION: Do not try to put the vehicle in
motion before pressure in the air system
reaches 100 psi (689 kPa) because the wheels
will still be locked by the spring brake action.
• Unnecessary stress and possible brake
malfunction could occur if the vehicle is
forced to move before the air system
reaches 100 psi (689 kPa).
Starting Procedure — Cold Temperatures
In addition to the previous “Normal Starting Procedures,”
use these Cold Weather Starting guidelines when the air
temperature falls below a certain temperature. Check
your Engine Operation and Maintenance Manual for fur-
ther details on when cold weather starting aids are
needed.
Using special cold-starting equipment will help the engine
start easier. And in cold weather, fast engine starting
helps relieve the loads on the electrical system and crank-
ing motor. If you follow these few simple guidelines, you
will extend the service life of your vehicle's engine:
• Keep the electrical system in top condition.
• Use the best quality and recommended grade of fuel
(see Engine Operation and Maintenance Manual).
• Use the recommended engine lubricating oil.
• As stated in the Normal Starting Procedures, when
temperatures are below normal, fully depress the
accelerator pedal after engaging the starter.
Engine Block Heater (Option)
To preheat the engine before starting, plug the optional
engine block heater into a properly grounded AC electrical
source. Do not start the engine with the heater plugged in.
WARNING! Engine block heaters can cause
fires resulting in death or serious personal
injury and/or property damage if not properly
maintained and operated. Regularly inspect
the engine block heater wiring and connector
for damaged or frayed wires. Do not use the
heater if there are any signs of problems. Con-
tact your Authorized Service Center or the
manufacturer of the heater if you are in need
of repairs or information.
