CAUTION
To avoid serious personal injury, you
must do the following.
Always make sure the hands and
other parts of the body of all occu-
pants are kept completely inside the
vehicle before you close the power
rear quarter windows. If someone’s
hands get caught in a closing win-
dow, it could result in a serious
injury. When anyone closes the
power rear quarter windows, make
sure that he/she operates the win-
dows safely.
Never leave small children alone in

tion key still inserted. They could
use the power rear quarter window

gage compartment. See ”Luggage stowage
precautions” in Part 2 for precautions to
observe for loading luggage.SEATBACK ANGLE ADJUSTING LEVER
Lean forward and pull the lever up.
Then lean back to the desired angle
and release the lever.
CAUTION
To reduce the risk of sliding under
the lap belt during a collision, avoid
reclining the seatback any more than
needed. The seat belts provide maxi-
mum protection in a frontal or rear
collision when the passengers are sit-
ting up straight and well back in the
seats. If you are reclined, the lap belt
may slide past your hips and apply
restraint forces directly to the abdo-
men. Therefore, in the event of a
frontal collision, the risk of personal
injury may increase with increasing
recline of the seatback.
