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.430) go off. If there is only a small
amount of fuel, the hybrid system may not be able to start. (The standard amount of
fuel is about 3.4 gal. [13 L, 2.8 Imp. gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.) ■
Electromagnetic waves ●
High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
●
Your vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
■
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can Hybrid system precautions Take care when handling the hybrid system, as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey th e warning labels attached to the vehi-
cle.

Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal. ■
Sensor detectio n information●
The following situations may occur
during use.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.■
Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below. ●
There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)●
A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected. ●
A sensor is covered in any way. ●
When a sensor or the area around a sen-
sor is extremely hot or cold. ●
On an extremely bumpy road, on an
incline, on gravel, or on grass. ●
The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves. ●
There is another vehicle equipped with
parking assist sensors in the vicinity. ●
A sensor is coated with a sheet of spray
or heavy rain. ●
If a sensor is hit by a large amount of
water, such as when driving on a flooded
road. ●
If the vehicle is significantly tilted. ●
The vehicle is approaching a tall or
curved curb. ●
If objects draw too close to the sensor. ■
Objects which may not be properly
detected
The shape of the object may prevent the
sensor from detectin g it. Pay particular
attention to the following objects: ●
Wires, fences, ropes, etc. ●
Cotton, snow and other materials that
absorb sound waves ●
Sharply-angled objects ●
Low objects ●
Tall objects with upper sections project-
ing outwards in the direction of your vehi-
cle
People may not be de tected if they are
wearing certain types of clothing.

such as a rain coat, long skirt, etc., making
their silhouette obscure
• Pedestrians whose body is partially hid-
den by an object, such as a cart or
umbrella
• Pedestrians which are obscured by dark-
ness, such as at night●
In some situations, such as the following,
pedestrians may not be detected by the
rear camera detection function, prevent-
ing the function from operating properly:
• When backing up in inclement weather
(rain, snow, fog, etc.)
• When the rear camera is obscured (dirt,
snow, ice, etc. are attached) or scratched
• When a very bright light, such as the sun,
or the headlights of another vehicle,
shines directly into the rear camera
• When backing up in a place where the
surrounding brightness changes sud-
denly, such as at the entrance or exit of a
garage or underground parking lot
• When backing up in a dim environment
such as during dusk or in an underground
parking lot●
Even though there are no pedestrians in
the detection area, some objects, such as
the following, may be detected, possibly
causing the rear camera detection func-
tion to operate.
• Three dimensional objects, such as a
pole, traffic cone, fence, or parked vehi-
cle
• Moving objects, such as a car or motor-
cycle
• Objects moving toward your vehicle
when backing up, such as flags or pud-
dles (or airborne matter, such as smoke,
steam, rain, or snow)
• Cobblestone or gravel roads, tram rails,
road repairs, white lines, pedestrian
crossings or fallen leaves on the road
• Metal covers (gratings), such as those
used for drainage ditches • Objects reflected in a puddle or on a wet
road surface
• The roadside or bumps on the road
•Shadows on the road ●
In some situations, such as the following,
the rear camera detection function may
operate even though there are no pedes-
trians in the detection area.
• When backing up toward the roadside or
a bump on the road
• If the vehicle is signif icantly tilted, such as
when carrying a heavy load
• When backing up toward an
incline/decline
• If the suspension has been modified or
tires of a size othe r than specified are
installed
• If the rear of the vehicle is raised or low-
ered due to the carried load
• If an electronic component, such as a
backlit license plate or rear fog light, is
installed near the rear camera
• If a bumper protector, such as an addi-
tional trim strip, is installed to the rear
bumper
• If the orientation of the rear camera has
been changed due to a collision or other
impact, or removal and installation
• If a towing eyelet is in stalled to the rear of
the vehicle
• When water is flowing over the rear cam-
era lens
• When the rear camera is obscured (dirt,
snow, ice, etc. are at tached) or scratched
• If there is a flashing light in the detection
area, such as the emergency flashers of
another vehicle ●
Situations in which the rear camera
detection function may be difficult to
notice
• If buzzer may be difficult to hear if the
surrounding area is noisy, the volume of
the audio system volume is high, the air
conditioning system is being used, etc.
• If the temperature in the cabin is
extremely high or low, the audio system
screen may not operate correctly.

Driving 4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( → P.298)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( → P.78, 83)
Shift the shift position to D when
stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift position
to P when parking. When using the N
position, there is no positive effect on
fuel consumption. In the N position, the
gasoline engine operates but electric-
ity cannot be generated. Also, when
using the air conditio ning system, etc.,
the hybrid battery (traction battery)
power is consumed.  Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.Hybrid vehicle driving tips For economical and ecological
driving, pay attention to the follow-
ing points:
Using Eco drive mode
Use of Hybrid System Indicator
Changing the shift position Accelerator pedal/brake pedal
operation
When braking
Delays

308 4-6. Driving tips
LS500h_OM_OM50F42U_(U) Control and maintain the vehicle at a
constant speed. 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
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season. Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.Highway driving
