Shiftlock release
The gear selector is locked in
the P position. To manually
release the shift lock, turn the
starting (ignition) key to
position I and press firmly on
the "OVERRIDE" button
(located under the cover near
the base of the gear selector -
see illustration). While
holding the override button
down, move the gear selector
from the (P)ark position. Electrical system
When replacing the battery or
when carrying out work
involving the electrical
system, the following should
be observed:
l A battery connection to the
wrong terminal will damage
the diodes. Before
connections are made, check
the polarity of the battery
with a voltmeter.
l If booster batteries are used
for starting, they must be
properly connected to
minimize the risk of the diode
being damaged.
For correct connection, see
"Jump starting" section.
l Never disconnect the
battery circuit (for example,
to replace the battery) while
the engine is running, as this
will immediately ruin the
generator. Always make sure
that all the battery
connections are properly
tightened.
l If any electrical-welding
work is performed on the
vehicle, the battery's ground
lead (negative cable) and all
the connecting cables of the
generator must be
disconnected and the welder
cables placed as near the
welding point as possible.
l The radio must be turned
off before the battery is
disconnected.
l If the radio has an antitheft
code and the battery has been
WARNING!
The Supplemental Restraint
System is grounded under the
driver's seat. Do not loosen the two
screws grounding the unit. Do not
ground other electrical
components using these screws or
any other points near them. Faults
in the system could occur if it is
improperly grounded.

Only use wheel lift or flat bed equipment.
CAUTION:
Sling-type equipment applied at the front will
damage radiator and air conditioning lines.
It is equally important not to use slingtype
equipment at the rear or apply lifting equipment
inside the rear wheels: serious damage to the
rear axle may result.
WARNING!
Do not use the towing eyelets on the car to pull
the car up onto a flat bed tow truck.
Jump starting pg. 65
Jump starting Check that cars are not touching to prevent
premature completion of negative circuit. Note the position
of the battery terminals and using jumper cables, first
connect booster battery positive (+) terminal (1) to car
battery positive (+) terminal (2). Then connect the 12 volt
booster battery negative (-) terminal (3) to a stationary solid
metal part on the engine at a point away from the battery
(4).
Do not connect booster cable to any part of fuel system or
any moving parts. Avoid touching hot manifolds. After
engine has started, remove first the negative (-) terminal
jumper cable. Then remove the positive (+) terminal jumper
WARNING!
l To reduce the possibility of
explosion, never expose battery to
open flame or electric spark.
l Do not smoke near battery.
l Batteries generate hydrogen gas
which is flammable and explosive.
l Battery fluid contains sulfuric
acid. Do not allow battery fluid to
contact eyes, skin, fabrics or painted
surfaces. If contact occurs, flush
affected area immediately with
water.
l Obtain medical attention
immediately if eyes are affected.
Failure to follow the instructions for
jump starting can lead to personal
injury.
CAUTION: Improper hook-up of
jumper cables or use of other than 12-
volt batteries could result in damage
to equipment and/or battery.
