1-3. Opening, closing and locking the doors and trunk
1
Before driving
■Closing the front doors from outside with the inside lock button set in the locked
position
The door cannot be locked if the power switch is in “ACC” or “IG-ON” mode, or
the e
lectronic key is left in the vehicle. (However, depending on the key's location,
the system may not be able to detect it. In these instances the door lock protection
function will not operate properly.)
■Using the mechanical key
The doors can also be locked and unlocked with the mechanical key. ( P.
4 6 9 )
■Customization
Settings (e.g. unlocking function using a key) can be changed. (P. 5 0 0 )
CAUTION
■To prevent an accident
Observe the following precautions while driving the vehicle. 
Failing to do so may result in a door openin g and an occupant falling out, resulting in
death or serious injury.
●Always use a seat belt.
●Always lock all doors.
●Ensure that all doors are properly closed.
●Do not pull the inside handle of the front door while driving.
●Set the rear door child protector locks when children are seated in the rear seat.

1-3. Opening, closing and locking the doors and trunk
1
Before driving
CAUTION
■Caution while driving
Keep the trunk lid closed.
This not only keeps personal belongings from being thrown out, but also prevents
exhaust gases from entering the vehicle.
■When children are in the vehicle
Never leave children unattended in the vehicle as they may lock themselves in the
vehicle or trunk, which could cause the child to overheat or suffocate resulting in
death or serious injury.
■When the trunk has not been fully closed
Be careful that your fingers do not get caught by the trunk lid when it is closing auto-
matically.
NOTICE
■To avoid damage to the trunk lid closer
Do not apply excessive force when the closer is operating.

1-4. Adjustable components
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 befo re 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. 1 6 7 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudd e
n 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 bel
t 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. 8 7 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. ( P. 4 2 )
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.

1-4. Adjustable components
CAUTION
■Wearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of sud-
den braking or an accident. Failing to do so may cause death or serious injury.
●Ensure that all passengers wear a seat belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at the same time, including children.
●Children should be seated in the rear se at and always use a seat belt and/or an
appropriate child restraint system.
●Do not recline the seat any more than necessary to achieve a proper seating
position. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from injury.
●Ensure that the belt and tab are locked and the belt is not twisted. If the seat belt
does not function correctly, immediately contact your Lexus dealer.
●Replace the seat assembly, including the belt s, if your vehicle has been involved in
a serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify , disassemble or dispose of a seat belt.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may cause it to activate or operate improperly and may
cause death or serious injury.
