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 367.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds before
trying again.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.
