FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a
rocking motion. Turn the steering wheel right
and left to clear the area around the front
wheels. For vehicles with automatic trans-
mission, push and hold the lock button on
the gear selector. Then shift back and forth
between DRIVE and REVERSE (with auto -
matic transmission) or SECOND GEAR and
REVERSE (with manual transmission), while
gently pressing the accelerator.
NOTE:
For vehicles with automatic transmission:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two
seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking
motion without spinning the wheels or racing
the engine. NOTE:
Push the “ESC OFF” switch (if necessary), to
place the Electronic Stability Control (ESC)
system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake
Control System” in “Safety” for further infor
-
mation. Once the vehicle has been freed,
push the "ESC OFF" switch again to restore
“ESC On” mode.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating
and failure. Allow the engine to idle with
the transmission in NEUTRAL for at
least one minute after every five
rocking-motion cycles. This will mini -
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
When “rocking” a stuck vehicle by
shifting between DRIVE/SECOND GEAR
and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drive -
train damage may result.
Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also
damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.

Cooling System
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with fresh OAT coolant (conforming
to MS.90032) by an authorized dealer.
Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty,
clean by gently spraying water from a garden
hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the
entire system for leaks. DO NOT REMOVE
THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Adding Washer Fluid
The windshield and rear window washers
share the same fluid reservoir. The fluid
reservoir is located in the front of the engine
compartment. Be sure to check the fluid
level in the reservoir at regular intervals. Fill
the reservoir with windshield washer solvent
(not radiator antifreeze) and operate the
system for a few seconds to flush out the
residual water.
When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth
or towel and wipe clean the wiper blades,
this will help blade performance.To prevent freeze-up of your windshield
washer system in cold weather, select a solu
-
tion or mixture that meets or exceeds the
temperature range of your climate. This
rating information can be found on most
washer fluid containers.
Brake System
In order to ensure brake system perfor -
mance, all brake system components should
be inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
CAUTION!
Do not travel with the windshield washer
fluid reservoir empty: the windshield
washer is essential for improving visibility.

RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect
the stability of the vehicle and can produce
a feeling of sluggish response or over respon
-
siveness in the steering. NOTE:
Unequal tire pressures from side to side
may cause erratic and unpredictable
steering response.
Unequal tire pressure from side to side
may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump -
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort -
able ride. Over-inflation produces a jarring
and uncomfortable ride.
WARNING!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that
result in tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.
Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pres-
sure.

Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the left side B-Pillar or rear edge of
the passenger door.Tire And Loading Information Placard
This placard tells you important information
about the:
1. Number of people that can be carried in the vehicle.
2. Tire size designed for your vehicle.
3. Cold tire inflation pressures for the front, rear, and spare tires. At least once a month:Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when deter
-
mining proper inflation. Tires may look
properly inflated even when they are
under-inflated.
Inspect tires for signs of tire wear or visible
damage.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”.
Cold tire inflation pressure is defined as the
tire pressure after the vehicle has not been
driven for at least three hours, or driven less
than one mile (1.6 km) after sitting for a
minimum of three hours. The cold tire
inflation pressure must not exceed the
maximum inflation pressure 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°F (7°C) of air temperature
change. Keep this in mind when checking
tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) 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.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions 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
CAUTION!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which could
damage the valve stem.
