■Reclining adjustment
Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of sliding under the lap belt.
If the seat is too reclined, during an accident the lap belt may slide past the hips and
apply restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury.

Driving position memory system (if equipped)
Your preferred driving position (the position of the driver’s seat, steering
wheel and outside rear view mirrors) can be entered into the computer’s
memory and recalled with the touch of a button. It is also possible to set this
function to activate automatically when the doors are unlocked.
Three different driving positions can be entered into memory.
The same buttons are found on the front passenger’s side, allowing the
position of the front passen ger’s seat to be memorized.
■Entering a position to memory

Turn the “POWER” switch to ON mode.
Adjust the driver’s seat, steering wheel, and outside rear view
mirrors to the desired positions. While pushing the “SET” button,
push button “1”, “2” or “3” until
the signal beeps.
If the selected button has
already been preset, the previ-
ously recorded position will be
overwritten.

Seat belt comfort guide (outboard rear seats)If the shoulder belt fits close to a
person’s neck, slide the seat belt
comfort guide forward.
Seat belt pretensioners (front and outboard rear seats)The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.

Pre-collision seat belts (front seats of vehicles with pre-collision system)
When the pre-collision sensor detects an obstacle and determines that a
collision is unavoidable, the seat belts lessen collision injury by retracting
the slack in the front seat belts before the collision, thus restraining the
driver and passenger at an earlier stage.
The seat belts will also operate in the event of sudden braking. ( →P. 2 0 6 )
■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 too quickly. A slow, easy motion will allow the belt to extend, and
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 more. ( →P. 117)
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. (→P. 6 6 )
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.
