■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward or pull out the belt too quickly. Allow the belt to fully retract, and
then slowly extend the belt. If the belt ca nnot be pulled out of the retractor, firmly
pull the belt and release it. You will then be able to smoothly pull the belt out of the
retractor.
■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 more. ( →P. 113)
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. (→P. 60)
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.
Avoid belt contact over the rounding of the
abdominal area.
If the seat belt is not worn properly, not only a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking or a collision.

■Linked mirror function when reversing (vehicles with driving position memory)
The outside rear view mirrors will automatically angle downwards when the vehicle
is reversing in order to give a better view of the ground. However, this function will
not operate when the mirror select switch is in the neutral position (between “L” and
“R”).
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the outside
rear view mirrors will activate in conjunction with the anti-glare inside rear view mir-
ror to reduce reflected light. ( →P. 7 0 )
■Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it rains, the
rain clearing (hydrophilic) effect of the mirrors causes the droplets to be spread out
into a film making the rear view clearer. In the following cases, the rain clearing
effect will be reduced temporarily, but will return after 1 or 2 days' exposure to
direct sunlight.
●After wiping dirt off the mirrors
●When the mirrors fog up
●After waxing your vehicle in an automatic car wash
●After your vehicle has been parked for a long period in underground parking
lots, etc. where there is no direct sunlight
