■Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
■Conditions affecting operation
The smart access system with push-button st art, wireless remote control and immobilizer
system use weak radio waves. In the following situations, the communication between the
electronic key and the vehicle may be affect ed, preventing the smart access system with
push-button start, wireless remote control an d immobilizer system from operating prop-
erly. (Ways of coping: P. 564)

 P. 121
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als 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.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress the brake and accelerator pedals properly.
• 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 accident.
●The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those
of the brake discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the shift lever is in any position other than P or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the ve hicle rolling away, always keep depressing
the brake pedal while stopped with the “REA DY” indicator is illuminated, 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, alwa ys 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 material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, sp ray 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 cau se the plastic lenses and plastic mate-
rial 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 circui t 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 windsh ield or windows. Do not place containers
such as air fresheners on th e instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, ca using a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metallized
film such as a silver-colored one. Reflecte d sunlight may cause the glass to act as a
lens, causing a fire.
●Always shift the shift lever to P, apply the parking brake, stop th e hybrid system and
lock the vehicle.
Do not leave the vehicle unattended whil e the “READY” indicator is illuminated.
●Do not touch the exhaust pipes while the “R EADY” indicator is illuminated or imme-
diately after turning the hybrid system off.
Doing so may cause burns.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to hybrid system
overheating. Additionally, if the vehicle is parked in a poorly ve ntilated area, exhaust
gases may collect and enter the vehicle, lead ing to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle.
●If the electronically controlled brake function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, bu t the brake pedal should be depressed more
firmly than usual. Also, the braking distan ce will increase. Have your brakes fixed
immediately.
●The brake system consists of 2 or more indi vidual hydraulic systems; if one of the sys-
tems fails, the other(s) will still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase. Have your
brakes fixed immediately.
■If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessive ly when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage the driveline components or propel the vehi-
cle forward or backward, causing an accident.

WARNING
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
●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 luggage compartment whenever possible.
●Do not stack cargo and luggage in the luggage compartment higher than the seat-
backs.
●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 luggage compartment. It is not designed for pas-
sengers. They should ride in their seats with their se at 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 luggage cover
• On the instrument panel
• On the dashboard
●Secure all items in the occupant compartment.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle weight rating.
●Even if the total load of occupant’s weight and the cargo load is less than the total load
capacity, do not apply the load unevenly. Improper loading may cause deterioration
of steering or braking control which may cause death or serious injury.
■Roof luggage carrier precautions
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly between the front and rear
axles.
●If loading long or wide cargo, never exceed the vehicle overall length or width.
(  P. 582)
●Before driving, make sure the cargo is secu rely fastened on the roof luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of gravity of the vehi-
cle higher. Avoid high speeds, sudden star ts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly and result in death or serious injury.
●If driving for a long distance, on rough road s, or at high speeds, stop the vehicle now
and then during the trip to make sure the cargo remains in its place.
●Do not exceed 165 lb. (75 kg) cargo weight on the roof luggage carrier.

EV drive mode
In EV drive mode, electric power is su pplied by the hybrid battery (traction
battery), and only the electric motor (traction motor) is used to drive the vehi-
cle.
This mode allows you to drive in reside ntial areas early in the morning and late
at night, or in indoor parking lots, etc., without concern for noises and gas
emissions.
However, when the vehicle proximity noti fication system is active, the vehicle
may produce sound.
