or clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
•ALWAYS securely attach
your floor mat using
the floor mat fasteners. DO NOT install your floor
mat upside down or turn your floor mat over.
Lightly pull to confirm mat is secured using the
floor mat fasteners on a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE
before installing any
other floor mat. NEVER install or stack an addi-
tional floor mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle.

to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•Before exiting a vehicle, always shift the transmis-
sion into PARK, apply the parking brake and remove
the key fob from the ignition. When leaving the
vehicle, always lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children
should be warned not to touch the parking brake,
brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children. A child could oper-
ate 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 gear
selector 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 gear selector must be in the PARK or NEUTRAL
position before you can start the engine. Press the brake
pedal before shifting to any driving gear.
NOTE: You must press the brake pedal before shifting out
of PARK.
Tip Start
Do not press 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
6
STARTING AND OPERATING 195

engine fails to start, the starter will disengage automati-
cally in 10 seconds. If this occurs, turn the ignition switch
to the LOCK position, wait 10 to 15 seconds, 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” proce-
dure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion 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,
(Continued)
WARNING!(Continued)
so follow the procedure carefully. Refer to “Jump-
Starting” in “In Case Of Emergency” for further infor-
mation.
Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
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. Press 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 “Nor-
mal Starting” procedure.
196 STARTING AND OPERATING

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 is controlled automatically, and it will
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.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Dealer
Service” in “Servicing And Maintenance”.
6
STARTING AND OPERATING 197

CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as a problem.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave an auto-
matic transmission in PARK, or manual transmission in
REVERSE or first gear.
The parking brake lever is located in the center console. To
apply the parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the lever up
slightly, push the center button, then lower the lever
completely. When the parking brake is applied with the ignition switch
in the ON position, the “Brake Warning Light” in the
instrument cluster will illuminate.
NOTE:
•
When the parking brake is applied and the automatic
transmission is placed in gear, the “Brake Warning
Light” will flash. If vehicle speed is detected, a chime
will sound to alert the driver. Fully release the parking
brake before attempting to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application.
Parking Brake
198 STARTING AND OPERATING

MANUAL TRANSMISSION
Five-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the vehicle
unattended without having the parking brake fully ap-
plied. The parking brake should always 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.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 a gear higher than first gear.
CAUTION!
•
Launching in any gear except 1st gear will result in
excessive slipping of the clutch and potentially lug-
ging or stalling the engine.
• 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 a gear higher
than first gear.
For most city driving, you will find it easier to use only the
lower gears. For steady highway driving with light accel-
erations, 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.
Shift Pattern
200 STARTING AND OPERATING

NOTE:During cold weather, until the transmission lubri-
cant 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.

STARTING AND OPERATING 201

Downshifting
Proper downshifting will improve fuel economy and pro-
long engine life.
CAUTION!
If you skip a gear while downshifting or downshift at
too high of a vehicle speed, these conditions may cause
the engine to overspeed if too low of a gear is selected
and the clutch pedal is released. Damage to the clutch
and the transmission can result from skipping a gear
while downshifting or downshifting at too high of a
vehicle speed even if the clutch pedal is held pressed
(i.e., not released).
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 overbur-
dened.
AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
• Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
