STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Do not leave the key in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
Manual Transmission – If Equipped
Before starting the engine fully apply the parking brake,
press the clutch pedal to the floor, and place the shift
lever in NEUTRAL.NOTE:
•The engine will not start unless the clutch pedal is
pressed to the floor.
•If the key will not turn and the steering wheel is
locked, rotate the wheel in either direction to relieve
pressure on the locking mechanism and then turn the
key.
Automatic Transmission – If Equipped
The shift lever must be in the PARK or NEUTRAL
position before you can start the engine. Apply the brakes
before shifting to any driving gear.
NOTE:
You must press the brake pedal before shifting
out of PARK.5
STARTING AND OPERATING 289

Tip Start
Do notpress the accelerator. Turn the ignition switch to
the START position and release it as soon as the starter
engages. The starter motor will continue to run, and it
will disengage automatically when the engine is running.
If the engine fails to start, the starter will disengage
automatically in 10 seconds. If this occurs, turn the
ignition switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting” procedure.
Normal Starting
Normal starting of either a cold or a warm engine does
not require pumping or pressing the accelerator pedal.
Simply turn the ignition switch to the START position
and release when the engine starts. If the engine fails to
start within 15 seconds, turn the ignition switch to the
OFF position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
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
another vehicle. This type of start can be dangerous if
done improperly, so follow the procedure carefully.
Refer to “Jump Starting” in “What To Do In Emer-
gencies” for further information.
Extreme Cold Weather (Below –20°F or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
290 STARTING AND OPERATING

If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” and “Extreme Cold Weather” proce-
dures, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there. Crank the engine
for no more than 15 seconds. This should clear any excess
fuel in case the engine is flooded. Leave the ignition key
in the ON position, release the accelerator pedal and
repeat the “Normal Starting” procedure.
WARNING!
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.
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.
After Starting
The idle speed will automatically decrease as the engine
warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, 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.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.

STARTING AND OPERATING 291

WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
MANUAL TRANSMISSION — IF EQUIPPED
Five–Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.Fully press the clutch pedal before you shift gears. As you
release the clutch pedal, lightly press the accelerator
pedal.
Shift Pattern
292 STARTING AND OPERATING

Use each gear in numerical order, do not skip a gear. Be
sure the transmission is in first gear, (not third), when
starting from a standing position. Damage to the clutch
can result from starting in third gear.
For most city driving, you will find it easier to use only
the lower gears. For steady highway driving with light
accelerations, fifth gear is recommended.
Never drive with your foot resting on the clutch pedal,
and never try to hold the vehicle on a hill with the clutch
pedal partially engaged. This will cause abnormal wear
on the clutch.
Never shift into REVERSE until the vehicle has come to a
complete stop.
NOTE:During cold weather, until the transmission
lubricant is warm, you may experience slightly higher
shift efforts. This is normal and not harmful to the
transmission.Recommended Shift Speeds
To use your manual transmission for optimal fuel
economy, it should be upshifted as listed in the following
table.
Manual Transmission Recommended Shift Speeds
Units in mph (km/h)
Engine Size Accel-
eration Rate 1to2 2to3 3to4 4to5
All En- gines Accel 14 (23) 23 (37) 29 (47) 45 (72)
Cruise 12 (19) 18 (29) 25 (40) 32 (52)
Downshifting
Proper downshifting will improve fuel economy and
prolong engine life.
5
STARTING AND OPERATING 293

CAUTION!
If you skip more than one gear while downshifting
or downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.
To maintain a safe speed and prolong brake life, shift
down to second or first gear when descending a steep
grade.
When turning a corner or driving up a steep grade,
downshift early so that the engine will not be
overburdened.
AUTOMATIC TRANSMISSION — IF EQUIPPED
NOTE: The Continuously Variable Automatic Transmis-
sion (CVT) changes ratios in a continuous manner. This
may sometimes “feel” as if it is slipping, but this is
normal and does not harm anything.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
NOTE: You MUST press and hold the brake pedal down
while shifting out of PARK.
294 STARTING AND OPERATING

WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and when your foot is
firmly on the brake pedal.
Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON or START position, and
the brake pedal is pressed.
Brake/Transmission Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the ON or
START position. To move the shift lever out of the PARK
position, the ignition switch must be turned to the ON or
START position (engine running or not) and the brake
pedal must be pressed before attempting to move the
lever.

STARTING AND OPERATING 295

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, and then place the
shift lever in the PARK position.
WARNING!
•Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should
always shift the vehicle into PARK, remove the
key from the ignition, and apply the parking
brake. Once the key is removed from the ignition,
the shift lever is locked in the PARK position,
securing the vehicle against unwanted movement.
Furthermore, you should never leave unattended
children inside a vehicle.

296 STARTING AND OPERATING

WARNING! (Continued)
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the
ignition key in the ignition switch. A child could
operate power windows, other controls, or move
the vehicle.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, firmly move the shift lever
all the way forward until it stops.
•Look at the instrument cluster to ensure it is in the
PARK position.
CAUTION!
Before moving the shift lever out of PARK, you must
turn the ignition from LOCK to ON so the steering
wheel and shift lever are released. Otherwise, dam-
age to the steering column or shift lever could result.
You must also press the brake pedal.
REVERSE
This range is for moving the vehicle rearward. Use this
range only after the vehicle has come to a complete stop.
NEUTRAL
This range is used when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake and
shift the transmission into PARK if you must leave the
vehicle.
