244 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in ªNº (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system. It will not start unless the
clutch pedal is pressed to the floor.
Automatic Transmission
Start the engine with the selector lever in the ªNº
(Neutral) or ªPº (Park) position. Apply the brake before
shifting to any driving range.
Normal Starting
Normal starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the normal starting procedure.

Tip Start Feature Ð Automatic Transmission Only
Do notpress the accelerator. Turn the ignition key briefly
to START position, and release it. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running.
Extreme Cold Weather (below ±20ÉF or ±29ÉC)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
If Engine Fails to Start
If the engine fails to start after you have followed the
ªNormal Startingº or ªExtreme Cold Weatherº proce-
dures, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while cranking the
engine. This should clear any excess fuel in case the
engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
Ignition Key Positions
246 STARTING AND OPERATING

WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission 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.
Refer to Section 6 of this manual for proper jump
starting procedures and follow them carefully.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is

released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the ªNormal Startingº or ªExtreme Cold
Weatherº procedures should be repeated.
After Starting
The idle speed will automatically decrease as the engine
warms up.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
ENGINE BLOCK HEATER Ð IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded three-wire extension cord.
²The engine block heater cord is found under the hood
clipped to the heater line on the left side of the engine.
