CAUTION
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come
on when you start the hybrid system, this could mean that these systems are not
available to help protect you in an accident, which could result in death or seri-
ous injury. Have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional immediately if
this occurs.

1523-2. Opening, closing and locking the doors and trunk
IS300h_EE(OM53B95E)
Note for the entry function (if equipped)
Even when the electronic key is within the effective range (detection areas), the
system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the
rear bumper center when the trunk is opened.
Do not leave the electronic key on top of the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the doors will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle.
As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the electronic
key can be used to unlock the vehicle.
The doors may unlock or lock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash, when the electronic key is within the
effective range. (The doors will automatically be locked after approximately 30
seconds if the doors are not opened and closed.)
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.)
Touching the door lock or unlock sensor while wearing gloves may prevent
lock or unlock operation.
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In this case, follow the follow-
ing correction procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the vehi-
cle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry &
start system. (P. 150)
If the electronic key is inside the vehicle and a door handle becomes wet during
a car wash, a message may be shown on the multi-information display and a
buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.
The lock sensor may not work properly if it comes into contact with ice, snow,
mud, etc. Clean the lock sensor and attempt to operate it again, or use the lock
sensor on the lower part of the door handle.
A sudden handle operation or a handle operation immediately after entering the
effective range may prevent the doors from being unlocked. Touch the door
unlock sensor and check that the doors are unlocked before pulling the door
handle again.
Unlocking the vehicle may take more time if another electronic key is within
the effective range.

Operation of each component
IS300h_EE(OM53B95E)
Note for the push-start function
Even when the electronic key is within the effective range (detection areas), the
system may not operate properly when the electronic key is on the instrument
panel, rear package tray or floor, or in the door pockets or glove box when the
hybrid system is started or power switch modes are changed.
Even if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
When the vehicle is not driven for extended periods
Vehicles with entry function: To prevent theft of the vehicle, do not leave the
electronic key within 2 m (6 ft.) of the vehicle.
The smart entry & start system can be deactivated in advance. (P. 575)
To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the out-
side of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention function may not
operate.)
Do not leave the electronic key inside the luggage compartment.
The key confinement prevention function may not operate, depending on the
location of the key (close to a spare tire [if equipped], the inside edge of the lug-
gage compartment), conditions (inside a metal bag, close to metallic objects)
and the radio waves in the surrounding area. (P. 146)
If the smart entry & start system does not operate properly
Locking and unlocking the doors and opening the trunk: Use the mechanical
key.

Driving
IS300h_EE(OM53B95E)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When the vehicle is stopped
Do not depress the accelerator pedal unnecessarily.
If the shift lever is any position other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator on,
and apply the parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused by
the vehicle rolling forward or backward, always depress the brake pedal and
securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible mate-
rial is nearby.
When the vehicle is parked
Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior
of the vehicle, and may also cause a short circuit in the vehicle’s electrical
components.
Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place
such as the glove box or on the floor, it may be lit accidentally when luggage
is loaded or the seat is adjusted, causing a fire.
Do not attach adhesive discs to the windshield or windows. Do not place con-
tainers such as air fresheners on the instrument panel or dashboard. Adhesive
discs or containers may act as lenses, causing a fire in the vehicle.
Do not leave a door or window open if the curved glass is coated with a met-
allized film such as a silver-colored one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
Always apply the parking brake, shift the shift lever to P, stop the hybrid sys-
tem and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
Do not touch the exhaust pipes while the hybrid system is operating or imme-
diately after turning the hybrid system off.
Doing so may cause burns.

cargo capacity and load:
CAUTION
Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
Receptacles containing gasoline
Aerosol cans
Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may
block the driver’s vision, or may result in items hitting the driver or passengers,
possibly causing an accident.
Stow cargo and luggage in the trunk whenever possible.
To prevent cargo and luggage from sliding forward during braking, do not
stack anything in the enlarged trunk. Keep cargo and luggage low, as close to
the floor as possible.
When you fold down the rear seats, long items should not be placed directly
behind the front seats.
Never allow anyone to ride in the enlarged trunk. It is not designed for pas-
sengers. They should ride in their seats with their seat belts properly fastened.
Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
• In front of the navigation system screen (if equipped) or Lexus Display
Audio screen (if equipped)
Secure all items in the occupant compartment.
Load and distribution
Do not overload your vehicle.
Do not apply loads unevenly.
Improper loading may cause deterioration of steering or braking control
which may cause death or serious injury.
