For safety and security
Push the seat belt shoulder
anchor down while pressing the
release button.
Push the seat belt shoulder
anchor up while pressing the
release button.
Move the height adjuster up and
down as needed until you hear a
click.
The pretensioners help the seat
belts to quickly restrain the occu-
pants by retracting the seat belts
when the vehicle is subjected to
certain types of severe frontal or
side collision or a vehicle rollover.
The pretensioners do not activate
in the event of a minor frontal
impact, a minor side impact or a
rear impact.
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on imp act. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted
even slightly, the belt is locked in that position and cannot be extended. This
feature is used to hold the child restraint system (CRS) firmly . To free the belt
again, fully retract the belt and then pull the belt out once m ore.

• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If a vehicle ahead is a child sized bicycle, a bicycle that is carrying a large
load, a bicycle ridden by more than one person, or a uniquely shaped

denly, such as at the entrance or exit of a tunnel

lowing situations:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When mud, snow, ice, a sticker, etc. is covering the sensor or surround-
ing area on the rear bumper
• When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching with only a small gap b etween
each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your v ehicle and
the vehicle that enters the detection area
• When the difference in speed between your vehicle and another vehicle
is changing
• When a vehicle enters a detection area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a vehicle remains in the d etection area
• When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.

enters the detection area is short
• When driving up and down consecutive steep inclines, such as h ills, dips
in the road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane,
and a vehicle traveling in a lane other than the adjacent lanes enters the
