Window Fogging
Vehicle side windows tend to fog on the inside in mild
rainy or humid weather. To clear the windows, use the
A/C, PANEL and blower controls. Direct the panel
outlets toward the side windows. Do not use recirculate
without A/C for long periods as fogging may occur.
Interior fogging on the windshield can be quickly re-
moved by using the defrost position.
If the fogging problem persists, clean the inside window
surfaces. The cause of undue fogging may be dirt collect-
ing on the inside surface of the glass
NOTE:In cold weather, the use of the recirculate
position will cause windows to fog on the inside because
of moisture build up inside the vehicle. For maximum
defogging, use the Outside Air position.
Summer Operation
Air conditioned vehicles must be protected with a high-
quality antifreeze coolant to provide proper corrosion
protection and to raise the boiling point of the coolant for
protection against overheating. A 50% concentration is
recommended.
Outside Air Intake
When operating the system during the winter months,
make sure the air intake, directly in front of the wind-
shield, is free of ice, slush, snow or other obstructions
such as leaves. Leaves collected in the air-intake plenum
may reduce air flow and plug the plenum water drains.
The blower air will heat faster in cold weather if you use
only a low blower speed for the first few minutes of
vehicle operation.

278 STARTING AND OPERATING

If Engine Fails to Start
If the engine fails to start after you have followed the
ªNORMAL STARTINGº procedure, 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
ªNORMAL STARTINGº 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.
Turbocharger ªCool Downº
NOTE:Letting the engine idle after severe operation
allows the turbine housing to cool to normal operating
temperature.
The following chart should be used as a guide in deter-
minning the amount of engine idle time required to
sufficiently cool down the turbocharger before shut
down, depending upon the type of driving and the
amount of cargo.
282 STARTING AND OPERATING

ª1º Low
This range should be used for maximum engine braking
when descending steep grades. In this range, up shifts
will occur only to prevent engine over speed while down
shifts from 2nd to first will occur as early as possible.
AUTOSTICK Ð IF EQUIPPED
Autostick is a driver-interactive transmission that offers
manual gear shifting capability to provide you with more
control. Autostick allows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Autostick Operation
The Autostick position is just below the Overdrive posi-
tion and is identified by the word ªAUTOSTICKº. When
you place the shift lever in the Autostick position, it can
be moved from side to side. Moving the lever to the left
(-) triggers a downshift and to the right (+) an upshift.
The gear position will be shown in the transmission gear
display, located in the instrument cluster.
You can shift in or out of the autostick mode at any time
without taking your foot off the accelerator pedal. If you
choose the Overdrive mode, the transmission will oper-
ate automatically; shifting between the four available
gears. When you wish to engage autostick, simply move
the shift lever to the AUTOSTICK position. The transmis-
sion will remain in the current gear until an upshift or
downshift is chosen.
Move the lever back to the Overdrive position to shift out
of the Autostick mode.
288 STARTING AND OPERATING

MANUAL TRANSAXLE OPERATION
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 depress the clutch pedal before you shift gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.
Use each gear in numerical order - do not skip a gear. Be
sure the transaxle is in FIRST gear, (not THIRD), when
starting from a standing position. Damage to the clutch
can result from starting in THIRD.

290 STARTING AND OPERATING

WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the
end of the steering wheel travel will increase the
steering fluid temperature and it should be avoided
when possible. Damage to the power steering pump
may occur.
TRACTION CONTROL SYSTEM Ð IF EQUIPPED
The Traction Control System (TCS) will improve accel-
eration and steering on slippery surfaces by reducing tire
spin. The system reduces wheel slip and maintains
traction at the driving (front) wheels by engaging the
brake on the wheel that is losing traction. When this
occurs the TCS indicator lamp located above the instru-
ment cluster odometer will flash. The system operates at
speeds below 35 mph (56 km/h).
A push-button at the center of the instrument panel,
below the radio, turns the Traction Control System ON or
OFF.

300 STARTING AND OPERATING

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES Ð GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. SafetyÐ
WARNING!
²Improperly inflated tires are dangerous and can cause
accidents.
²Under inflation increases tire flexing and can result in
tire failure.
²Over inflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes can cause
damage that result in tire failure.
²Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
²Over inflated or under inflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
²Unequal tire pressures from one side of the vehicle to
the other can cause the vehicle to drift to the right or
left.
²Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
310 STARTING AND OPERATING

check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under inflated.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
ªcold tire inflation pressure.º Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least 3 hours, or driven less than 1 mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall.Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12 ÉF (7 ÉC) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.
Example: If garage temperature = 68 ÉF (20 ÉC) and the
outside temperature = 32 ÉF (0 ÉC) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12 ÉF (7 ÉC) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
312 STARTING AND OPERATING

Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don't drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
