WARNING
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening it. Failure to do so may cause the trunk lid to suddenly shut again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the surround-
ing area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the trunk is
about to open or close.
●Use caution when opening or closing the tr unk lid in windy weather as it may move abruptly in strong wind.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. Such
additional weight on the trunk lid may cause the lid to suddenly shut again after it is
opened.

opened fully. It is more difficult to open or close the trunk lid on an incline than on a level
surface, so beware of the trunk lid unexpect-
edly opening or closing by itself. Make sure that the trunk lid is fully open and secure
before using the trunk.
●When closing the trunk lid, take extra care to
prevent your fingers etc. from being caught.

To reduce the risk of sliding under the lap be lt during a collision, do not recline the seat
more than necessary. If the seat is too reclined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident. Adjustments should not be made while drivin g as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
