1. Before starting the engine, perform the engine pre-trip inspection and daily maintenance
checks in on "PRE-TRIP INSPECTION AND DAILY MAINTENANCE" page 217.
2. Make sure the parking brakes are engaged.
3. Place the transmission in neutral or depress the clutch pedal.
CAUTION
DO NOT crank the engine for more than
30 seconds at a time; wait two minutes
after each try to allow the starter to cool.
Failure to follow these instructions could
cause starter damage.
Note: Some starters are equipped with starter protection. If the engine is running, the
starter temperature is too high, the transmission is not in neutral or the clutch pedal is not
depressed, starter engagement is inhibited. Also, when the key is turned to the start position,
there is a one second delay before the starter is engaged.
4. Turn on the ignition with the switch key. Some tell-tales will come on in a routine check
that shows the bulbs and systems are OK If any of the tell-tales stay lit, that function of the
vehicle may not be operable. DO NOT operate the vehicle until the problem is repaired. For
an explanation of the tell-tales, Refer to the Driver Information Display Manual.
5. Turn the key to the start position. Release key as soon as the engine has started. For the
Volvo engine, the preheater can be engaged to help starting in cold temperatures.
CAUTION
If at start-up, or thereafter, the oil
pressure gauge indicates any drop in oil
pressure, the engine must be shut down
immediately. Failure to stop the engine
may cause major engine damage.
