6-4 Starting and Stopping Procedures

COLD WEATHER STARTING

When starting a cold engine, the intake air will be
warmed up with the intake air preheater. Turn the
ignition switch to the ON position. The intake air
preheater will not engage at coolant temperature
above 54°F (12°C). If the coolant temperature is
below 54°F (12°C), the intake air preheater will
engage and will light the preheater telltale between 0
and 50 seconds, depending on the engine coolant
temperature. Wait before the preheater telltale has
turned off before starting the engine.
Intake Air Preheater Telltale
If necessary, once the engine has started, the
preheater will re-engage (post heating) for the same
length of time as the preheat time.
WARNING
Volvo D13 Engine
This engine is equipped with an intake air
preheater. Never use ether or other combustible
starting aid fluid. Introduction of ether or similar
starting aids could cause a fire or explosion
resulting in severe property damage, serious
personal injury or death.
WARNING
Do not use ether or other combustible starting aid
fluid on any engine equipped with an intake air
preheater. If the engine is equipped with a
preheater, introduction of ether or similar starting
aids could cause a fire or explosion resulting in
severe property damage, serious personal injury or
death.
Engines not equipped with an intake air preheater
may, depending on coolant temperature, take longer
to start. If this should happen, DO NOT release the
ignition key until the engine has started (while still
observing the 15 second maximum cranking time).

JUMP STARTING

In order to avoid damage to solid- state electrical
components, it is important that jumper (booster)
cables are used correctly and only in emergencies.
To jump start, use another 24 volt DC, negative
grounded, power source. Use only jumper cables
rated at 500 cranking amperes.
Injury, explosion, battery acid damage or charging
system overload may result if these jump starting
procedures are not precisely followed.
Wear eye protection and remove rings, metal jew-
elry and watches with metal bands.
The battery could rupture or explode if jump started
when the run-down battery fluid is frozen or if the
battery fluid level is low. Check condition of run-
down battery before attempting to jump start.
The gases given off by batteries while jump
starting are explosive. Do not smoke near
batteries.
Do not let the two vehicles touch. Keep a walk-
through distance between the two vehicles. Make
sure positive (red) and negative (black) jumper
cable clamps do not touch.
Never connect the jumper cable to the negative
terminal post of the run-down battery.
Do not jump start if a maintenance-free battery has
a yellow test indicator. Have the battery replaced.
