Vehicle set-up:
1. Park the vehicle in a safe and level place.
2.
Apply the parking brake and press the park
button to engage the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indi-
cators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more than ap-proximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When the
pressure reaches the designated pres-
sure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds after
starting to inflate the tire, it indicates
that the TPMS with Tire Inflation Indi-
cator is not operating. • The TPMS will not activate the TPMS
with Tire Inflation Indicator under the
following conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice is not sufficient to inflate the tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
• If the TPMS with Tire Inflation Indicator does not operate due to TPMS interfer-
ence, move the vehicle about1m(3ft)
backward or forward and try again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of per-
forming in a variety of on-pavement and off-
road applications. This gives them a higher center of gravity than ordinary vehicles. An
advantage of higher ground clearance is a
better view of the road, allowing you to an-
ticipate problems. However, they are not de-
signed for cornering at the same speeds as
conventional 2-Wheel Drive vehicles any
more than low-slung sports cars are de-
signed to perform satisfactorily under off-
road conditions. If at all possible, avoid sharp
turns at high speeds. As with other vehicles of
this type, failure to operate this vehicle cor-
rectly may result in loss of control or vehicle
rollover.
In a rollover crash, an unbelted person is sig-
nificantly more likely to die than a person
wearing a seat belt.
For additional information, see “Driving safety
precautions” (P. 5-10).
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe and
prudent manner may result in loss of con-
trol or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-

steering wheel will return to the normal posi-
tion after the protection mechanism is
deactivated.
Condition A:
• When the engine is stalled or likely to bestalled
• When the steering wheel is held in the full lock position or when the front tire touches
an obstruction
• When the battery is discharged
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.
Condition B:
• When the steering wheel is operated re- peatedly or continuously while parking or
driving at a very low speed. In this case, the
power assist for the steering wheel will be
reduced.
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without oper-
ating the steering wheel, until the tempera-
ture of Direct Adaptive Steering cools down.
Avoid repeated steering wheel operations
that could cause Direct Adaptive Steering to
overheat. When the vehicle is tested on the 2–wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the engine off, restart the
engine, and then drive the vehicle for a period
of time.
The following conditions do not indicate a
malfunction of Direct Adaptive Steering:
• You may notice wider steering play when
the ignition switch is in the OFF or AUTO
ACC position compared to when it is in the
ON position.
• After the engine is started, the steering wheel may turn slightly even when driving a
straight road. To return to the normal posi-
tion, drive the vehicle on a straight road for
a period of time.
• After the engine is started, the steering wheel may move if the steering wheel was
turned to the fully locked position while the
ignition switch was in the OFF position.
• After the vehicle is tested on the 4–wheel dynamometer, the steering wheel may turn
slightly even when driving on a straight
road. To return the steering wheel to the
normal position, drive the vehicle on a
straight road for a period of time. You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
• When the engine is started or stopped.
• When the steering wheel is turned in the full
lock position.
