●Motorcycles travelin g in the same lane
●When water or snow thrown up by the surrounding vehicles hinders the detecting of
the sensor
■Conditions under which the ve hicle-to-vehicle distance control mode may not function
correctly
In the case of the following conditions, o perate the brake pedal (or accelerator pedal,
depending on the situ ation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not
operate properly.
●When the vehicle ahead of you decelerates suddenly
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)
●Preceding vehicle has an extremely high
ground clearance
●When the road curves or when the lanes are
narrow
●When steering wheel operation or your posi-
tion in the lane is unstable

Driving

◆Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆Highway driving
Control and maintain the vehicle at a co nstant speed. Before stopping at a toll
booth or similar, allow plenty of ti me to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out until it
and the interior of the vehicle are warm , it will consume fuel. Also, fuel con-
sumption can be improved by av oiding overuse of the heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pr essure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use tires that are appropriate for the season.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆Warming up before driving
Since the gasoline engine starts up an d cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeated ly warm up, which can lead to excess
fuel consumption.

●Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. And, utility vehi cles have a significantly higher rollover
rate than other types of vehicles.
●An advantage of the higher ground cl earance is a better view of the road
allowing you to anticipate problems.
●It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.
Utility vehicle precautions
This vehicle belongs to the utility vehicl e class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity.

WARNING
■Utility vehicle precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle:
●In a rollover crash, an unbelted person is si gnificantly more likely to die than a person
wearing a seat belt. Therefore, the driver and all passengers should always fasten
their seat belts.
●Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or vehicle rollover
causing death or serious injury.
●Loading cargo on the roof luggage carrier will make the ce nter of the vehicle gravity
higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly.
●Always slow down in gusty crosswinds. Be cause of its profile and higher center of
gravity, your vehicle is more sensitive to side winds than an ordinary passenger car.
Slowing down will allow you to have better control.
●Do not drive horizontally across steep slopes . Driving straight up or straight down is
preferred. Your vehicle (or any similar off- road vehicle) can tip over sideways much
more easily than forward or backward.
