KEYS AND LOCKS
Two keys are provided with each vehicle. Different lock
cylinders operated by a separate key are available as an
option for the sliding side load door and rear load doors.
EMERGENCY STARTING
• Never tow the vehicle to start because the surge
forward when the engine starts could cause a collision
with the tow vehicle.
• Engines in vehicles with automatic transmissions
cannot be started by towing or pushing the vehicle.
• To start the vehicle when the Energizer (battery) is
discharged, use a single auxiliary battery or
Energizer of the
same nominal voltage
the discharged battery, with suitable jum per cables.
• Make connections as set forth below under "Jump
Starting With Auxiliary (Booster) Battery" to lessen
the chance of personal injury or property damage.
Never expose battery to open flame
CAUTION:
or electric spark-battery action generates
hydrogen gas which is flammable and explo­
sive. Don't allow battery fluid to contact skin,
eyes, fabrics, or painted surfaces-fluid is a
sulfuric acid solution which could cause serious
personal injury or property damage. Wear eye
protection when working with battery.
Jump Starting With Auxiliary
(Booster) Battery
Both booster and discharged battery should be treated
carefully when using jum per cables. Follow
procedure outlined below, being careful not to cause
sparks:
1. Set parking brake and place automatic transmission
in "PARK" (neutral for manual transmission).
Turn off lights, heater and other electrical loads.
2. Remove vent caps from both the booster and the

discharged batteries. Lay a cloth over the open vent
wells of each battery. These two actions help reduce
the explosion hazard always present in either
battery when connecting "live" booster batteries to
"dead" batteries.
3. Attach one end of one jum per cable to the positive

vehicles to touch each other, as this could establish
a ground connection and counteract the benefits of
this procedure.
4. Attach one end of the remaining negative(—) cable
to the negative terminal (black color,

booster battery,
engine lift bracket on 6 cylinder models and the
delcotron mounting bracket on V-8 models (see
Figure 4) (do not connect directly to negative post
of dead battery)-taking care that clamps from one
cable do not touch the clamps on the other cable.
Do not lean over the battery when making this
connection.
Reverse this sequence exactly when removing the
jumper cables. Re-install vent caps and throw cloths
away as the cloths may have corrosive acid on them.

could result in: (1) personal injury caused by
electrolyte squirting out the battery vents, (2)
personal injury or property damage due to
battery explosion, (3) damage to the charging
system of the booster vehicle or of the
immobilized vehicle.
