• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch <power switch>
is turned off once and turned to IGNI- TION ON mode <ON mode> again
■If “Clean Parking Assist Sensor” is dis-played on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from
the sensor, the system should return to nor- mal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may appear or an obstacle may not be detected.
If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfunction” or “Park-ing Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor- mation display
There is a malfunction and the device may not be working properly.
Have the vehicle inspected by any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front and rear bumpers.
●Certain vehicle conditions and the sur-rounding environment may affect the ability of the sensor to correctly detect
obstacles. Particular instances where this may occur are listed below.• There is dirt, snow or ice on the sensor.
(Wiping the sensors will resolve this problem.)• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is fro-
zen the screen may show an abnormal dis-
play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.• On an extremely bumpy road, on an
incline, on grav el, 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 sensor in the vicinity.• The sensor is splashed with water or
heavy rain. • The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed. • The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.• People may not be detected if they are
wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particu-
lar attention to the following obstacles: • Wires, fences, ropes, etc.• Cotton, snow and other materials that
absorb sound waves • Sharply-angled objects•Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impos-
sible. • Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the
obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.

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.242)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.86)
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 conditioning 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.

4-6. Driving tips
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.
