WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P.
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● Be careful not to get any part of your body pinched by a seat.
■ Seat adjustment
●Be careful that the seat does not hit passengers or luggage.
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is reclined too far, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
■ After returning the rear seatbacks or installing seats
Observe the following precautions. Failure to do so may result in death or
serious injury.
●Make sure the seatback is securely locked by pushing it forward and rear-
ward on the top.
● Check that the seat belts are not twisted or caught in the seatback.
● Make sure the seat is locked in place by trying to shake the seatback and
lift up the seat cushion.

●Do not leave a seat in the vehicle if it has been disengaged from the floor.
● Do not sit on or place anything on a seat that has been removed from the

Driving
■Conditions that may trigger the system even if there is no possibility of a
collision
In any of the following situations where the frontal area of the radar sensor is
interrupted, the radar sensor may detect possibility of a frontal collision and
the system may be activated.
●When passing by an oncoming vehicle in a curve or a turn to the right or the
left.
● When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll
gate barrier, etc.)
● When there is a structural object (billboard, low ceiling, fluorescent light,
etc.) above the uphill road ahead
● When driving on a narrow road or through under a low overhead structure
(bridge, tunnel, fly-under, etc.)
● When driving on an uneven road surface
● When there is a metal object, bump, or protrusion on the road surface
● When vehicle’s front part is raised or lowered depending on loading condi-
tions
● When the direction of radar sensor is misaligned by strong impact applied
on an area around the radar sensor, etc.
● When there is an obstacle (guard rail, etc.) by the roadside at the entrance
to a curve
● When the front of your vehicle is pointing upwards (caused by towing a
trailer, during emergency towing or putting a heavy load in the luggage com-
partment etc.)
When the system is activated in the situations described above, there is also
a possibility that the seat belts will retract quickly and the brakes may be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.
■ Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the radar sens or cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
■ Situations in which the pre-collis ion system does not function properly
The system may not function effectively in situations such as the following:
● On roads with sharp bends or uneven surfaces
● If a vehicle suddenly moves in front of your vehicle, such as at an intersec-
tion
● If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
● In inclement weather such as heavy rain, fog, snow or sand storms
● When your vehicle is skidding such as the VSC system off
● When an extreme change in vehicle height occurs
● When the axis of the radar is out of adjustment
