automatically, run for 10 seconds, and then
disengage. Once this occurs, release the
accelerator pedal and brake pedal, wait 10 to
15 seconds, then repeat the “Normal Starting”

Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto-
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 323.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
CAUTION!
Never use non-detergent oil or straight mineral
oil in the engine or damage may result.
