CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that could result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts
the driver, such as adjusting controls, talking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the cigarette
lighter, the windows, the moon roof, or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to children.
■Disposal of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery having been removed, there
is a danger of serious electric shock if high voltage parts, cables and their connec-
tors are touched. In the event that your vehicle must be disposed of, the hybrid bat-
tery must be disposed of by your Lexus dealer or a qualified service shop. If the
hybrid battery is not disposed of properly, it may cause electric shock that can result
in death or serious injury.

■If a warning light comes on, a warning message is displayed, or the 12-volt battery
is disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.
■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electromag-
netic shielding, and therefore emit approximately the same amount of electro-
magnetic waves as conventional gasoline powered vehicles or home electronic
appliances.
●Your vehicle may cause sound interference in some third party-produced radio
parts.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
( → P. 505) go off. If there is only a small amount of fuel, the hybrid system may not
be able to start. (The minimum amount of fuel to add to make the low fuel level
warning light go out is about 2.6 gal. [10 L, 2.1 Imp.gal.], when the vehicle is on a
level surface. This value may vary when the vehicle is on a slope.)
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the
hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.

Best past fuel consumption
Average fuel consumption
Displays the average fuel con-
sumption between each reset of
the total average fuel consumption
on the multi-information display.
When resetting, if the total average
fuel consumption is better than the
best past fuel consumption, the
best past fuel consumption will be
updated.
These images are examples only, and may vary slightly from actual conditions.
■Resetting the consumption data
Selecting on the screen will reset the average fuel consump-
tion. Selecting on the screen will reset the past records.
Selecting will confirm resetting of all the data (except cruising range).
■Cruising range
Displays the estimated maximum distance that can be driven with the quantity of
fuel remaining.
This distance is computed based on your average fuel consumption.
As a result, the actual distance that can be driven may differ from that displayed.

Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in
normal conditions. In addition, the operation of the air conditioning system
(heating/cooling) will be minimized, improving the fuel economy.
(→ P. 1 6 2 )
■Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicate of Hybrid System
Indicator within Eco area. ( →P. 171)
■When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
■Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel consumption. Check traffic reports before leav-
ing and avoid delays as much as po ssible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward slightly
while avoiding overuse of the accelera tor pedal. Doing so can help control
excessive gasoline consumption.
■ Highway driving
Control your speed and keep at a constant speed. Also, before stopping at
a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater amount of electrical energy can be
retained when slowing down.

NOTICE
■Precautions for handling the card key
●Do not apply excess force when inserting the mechanical key into the card key.
Doing so may damage the card key.
●If the battery or card key terminals get wet, the battery may corrode and the card
key may stop working.
If the key is dropped into water, or if drinking water etc. is spilled on the key,
immediately remove the battery cover and wipe the battery and terminals. (To
remove the battery cover, lightly grasp and pull it.) If the battery is corroded, have
your Lexus dealer replace the battery.
●Do not crush the battery cover or use a screwdriver to remove the battery cover.
Forcibly removing the battery cover may bend or damage the key.
●If the battery cover is frequently removed, the battery cover may become loose.
●When installing the battery, make sure to check the direction of the battery.
Installing the battery in the wrong direction may cause the battery to deplete rap-
idly.
●The surface of the card key may be damaged, or its coating may peel off in the
following situations:
• The card key is carried together with hard objects, such as coins and keys.
• The card key is scraped with a sharp object, such as the tip of a mechanicalpencil.
• The surface of the card key is wiped with thinner or benzene.

1-3. Opening, closing and locking the doors
HS250h_U_75050U
■Notes for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent lock
operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition signals
will be shown up to two consecutive times. After this, no recognition signals will
be given.
●If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position 6 ft.
(2 m) or more separate from the vehicle while the vehicle is being washed. (Take
care to ensure that the key is not stolen.)
●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.
●Fingernails may scrape against the door during operation of the door handle.
Be careful not to injure fingernails or damage the surface of the door.
■Notes for the unlocking function
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the original
position and check that the doors unlock before pulling the door handle again.
●Gripping the door handle when wearing a glove may not unlock the door.
Remove the gloves and touch the sensor on the back of the handle again.
●If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position 6 ft.
(2 m) or more separate from the vehicle while the vehicle is being washed. (Take
care to ensure that the key is not stolen.)
●If there is another electronic key in the detection area, it may take slightly longer
to unlock the doors after the door handle is gripped.
●Fingernails may scrape against the door during operation of the door handle.
Be careful not to injure fingernails or damage the surface of the door.
