the rear seat facing the rear of the
vehicle.
Run the seat belt through the child
restraint system and insert the

Fully extend the shoulder strap and
then allow it to retract slightly into
the ALR lock mode.
Lock mode allows the seat belt to
retract only.
While pushing the child restraint
system into the rear seat, allow the
shoulder belt to retract until the
child restraint system is securely in
place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
If the child restraint has a top tether strap, the top tether strap
should be latched onto the top tether strap anchor. (

CAUTION
■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR lock
mode: (P. 7 8 )
ALR mode causes the belt to tighten only which could cause injury or discomfort to
the child.
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passen-
gers may be injured or even killed in the event of sudden braking, sudden swerving
or an accident.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it
does not interfere with the child restraint
system.
●Only put a forward-facing child restraint
system on the front seat when unavoidable.
When installing a forward-facing child
restraint on the front passenger seat, move
the seat as far back as possible even if the
“AIR BAG OFF” indicator light is illumi-
nated. Failing to do so may result in death
or serious injury if the airbags deploy
(inflate).

■For efficient use
●Put the shift lever into “D” when driving
In the “N” position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
●Drive your vehicle smoothly
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the traction motor without having to use
gasoline engine power.
●Avoid repeated acceleration
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Put the shift lever into “P” when parking
In the “N” position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the “N” position for an extended period of the time may
discharge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.

CAUTION
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in
operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly, allowing you to depress the brake and accelerator pedals prop-
erly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay response in an emergency, resulting in an acci-
dent.
●Do not drive the vehicle over or stop the vehicle near flammable materials. 
The exhaust system and exhaust gases can be extremely hot. This may cause a
fire if there is any flammable material nearby.
●Do not let the vehicle roll backwards while the shift lever is in a driving position, or
roll forward while the shift lever is in “R”.
Doing so may cause the hybrid system not to operate or lead to poor brake and
steering performance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed. 
Large amounts of exhaust in the vehicle can cause driver drowsiness and an acci-
dent, resulting in death or a serious health hazard. Have the vehicle inspected by
your Lexus dealer immediately.
●Do not shift the shift lever to "P" while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to "R" while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to "D" while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
