2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
CAUTION
Avoid reclining the seatback any
more than needed. The seat belts pro-
vide maximum protection in a frontal
or rear collision when the driver and
the front passenger are sitting up
straight and well back in the seats. If
you are reclined, the lap belt may
slide past your hips and apply re-
straint forces directly to the abdomen
or your neck may contact the shoul-
der belt. In the event of a frontal
collision, the more the seat is re-
clined, the greater the risk of death
or personal injury.
3. SEAT LUMBAR SUPPORT
ADJUSTING SWITCH
Press either side of the switch.
The amount of lumber support will change
while the switch is pressed.
CAUTION

Do not adjust the seat while the
vehicle is moving.

Be careful that the seat does not
hit a passenger or luggage.

Be careful not to get your hands or
feet pinched in the seat.

After adjusting the seat position, re-
lease the lever and try sliding the
seat forward and backward to make
sure it is locked in position.

After adjusting the seatback, push
your body back against the seat to
make sure the seat is locked in
position.

When returning the seatback to the
upright position, observe the follow-
ing precautions in order to prevent
personal injury in a collision or
sudden stop:
Make sure the seatback is securely
locked by pushing forward and rear-
ward on the top of the seatback.
Failure to do so will prevent the
seat belt from operating properly.
Make sure the seat belts are not
twisted or caught in the seatback
and are arranged in their proper
position and are ready to use.
Folding down the rear seatbacks will en-
large the luggage compartment. See
ÐStowage precautionsº on page 313 in
Section 2 for precautions when loading
luggage.
