IS250C/350C_U
●If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless remote control to unlock the doors.)
●A sudden approach to the effective range or door handle operation may prevent
the doors from being unlocked. In this case, return the door ha ndle to the original
position and check that the doors unlock before pulling the door handle again.
■When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m) of
the vehicle.
■Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the anti-theft system automatically locks the vehicle again.
■Alarms and warning indicators
A combination of exterior and interior alarms as well as warnings displayed on the
multi-information display are used to prevent theft of the vehicle and unforeseeable
accidents resulting from erroneous operation. Take appropriate measures in
response to any warning indications on the multi-information display. ( →P. 500)

IS250C/350C_U
CAUTION
■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 sur-
rounding 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 trunk 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.
●The trunk lid may suddenly shut if it is not
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
unexpectedly 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.
●When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.

IS250C/350C_U
CAUTION
■Seat 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, the lap belt may slide past the hips and apply restraint
forces directly to the abdomen or your neck may contact the shoulder belt, increas-
ing the risk of death or serious injury in the event of an accident.
■Retuning the folded seatback to the upright position
Pull the seatback up by hand.
If the seatback angle switch is used to return the seatback, the seat may not be
locked in position, resulting in an accident.
After returning the seat, rock the seat back and forth to ensure that it is securely
locked in position.
■When the vehicle is moving
Do not operate the seatback fold levers.
■Switch-operated “Front, Fold & Return” Seat
●Before operating the switch, ensure that no surrounding passengers or objects
are caught in the seat. Seat operation will not stop automatically, even if some-
thing becomes caught in the seat. This may result in death or serious injury.
●Do not operate the switch while the vehicle is moving.
