To Reset The Manual Park Release:
1. Pull upward on the tether strap, releasing
it from the “locked” position.
2. Lower the Manual Park Release lever
downward and to the right, into its original
position.
3. Tuck the tether strap into the base of the
console, and reinstall the cover.
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 transmission, push
and hold the lock button on the gear selector.
Then, shift back and forth between DRIVE
and REVERSE, while gently pressing the ac-
celerator. Use the least amount of accelerator
pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing
the engine.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 transmis-
sion remains in NEUTRAL for more than
2 seconds, you must press the brake pedal
to engage DRIVE or REVERSE.
• Push the "ESC Off" switch, to place the
Electronic Stability Control (ESC) system in
"Partial Off" mode, before rocking the ve-
hicle. Refer to “Electronic Brake Control
System” in “Safety” in your Owner’s
Manual for further details. Once the vehicle
has been freed, push the "ESC Off" switch
again to restore "ESC On" mode.
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 ve-
hicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
WARNING!
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating 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 shift-
ing between DRIVE/SECOND GEAR and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
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 and Vehicle Stability
• Economy
• Tread Wear
• Ride ComfortSafety
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 re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing 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
pressure.Both under-inflation and over-inflation 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 steer-
ing 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.
