■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 your Lexus
dealer.
■Sensor detectio n 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
frozen the screen may show an abnormal
display, 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 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 sensor in the vicinity.
• The sensor is coated with a sheet of spray 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, be cause 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 befo re the display is
shown and the warning beep sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to

sion System)
By independently controlling the
damping force of th e shock absorbers
for each of the 4 wheels according to
the road and driving conditions, this
system helps riding comfort with supe-
rior vehicle stability, and helps good
vehicle posture.
Also, the damping force changes
Driving assist systems
To keep driving safety and perfor-
mance, the following systems oper-
ate automatically in response to
various driving situations. Be aware,
however, that these systems are
supplementary and should not be
relied upon too heavily when oper-
ating the vehicle.
Summary of the driving assist
systems

2444-5. Using the driving support systems
depending on the selected driving
mode. (P.224)
■LDH (Lexus Dynamic Handling
system) (if equipped)
Provides integrated control of the

swerving on slippery road surfaces by
controlling the brakes, engine system> output, steering assist (if
equipped), and steering ratio (if
equipped)
■Secondary Collision Brake
When the SRS airbag sensor detects a
collision and the system operates, the
brakes and brake lights are automati-
cally controlled to reduce the vehicle
speed and help redu ce the possibility
of further damage due to a secondary
collision
■When the
TRAC/VSC/ABS/VGRS*/DRS* sys-
tems are operating
The slip indicator light will flash while the TRAC/VSC/ABS/VGRS
*/DRS* systems

situations.
In this event, the steering wheel may move
from its straight forward position, but it will
return when the system restarts.
●When the steering wheel is operated for
an extended period of time while the vehicle is stopped or is moving very
slowly
(on vehicles with LDH, DRS is disabled
together with VGRS)
●When the steering wheel has been held
fully to the left or right
The center position of the steering wheel
may change when VGRS is disabled. How-
ever, the position will return to normal after
VGRS is reactivated.
■When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its
straight forward position, but this will be
corrected automatically when driving.
■Sounds and vibrations caused by the
ABS, brake assist, VSC, TRAC, hill-start
assist control and VGRS systems
●A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the engine
is started or just after the
vehicle begins to move. This sound does
not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound

WARNING
●When driving over roads with potholes
or uneven surfaces
■TRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner-
ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on
slippery road surfaces.
●When Active Cornering Assist fre-
quently operates, Active Cornering
Assist may temporarily stop operating
to ensure proper operation of the
brakes, TRAC and VSC.
■Hill- start assist control does not
operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the TRAC/ABS/
VSC/VGRS*/DRS* is activated
The slip indicator light flashes. Always
drive carefully. Re ckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
*: Only when controlled by the VDIM
system.
■When the TRAC/VSC systems are
turned off
Be especially careful and drive at a speed
appropriate to the road conditions. As
these are the systems to help ensure
vehicle stability and driving force, do not
turn the TRAC/VSC systems off unless
necessary.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC and VSC systems will
not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspensi on will affect the
driving assist systems, and may cause a
system to malfunction.
■Secondary Collision Brake
Do not rely solely upon the Secondary
Collision Brake. This system is designed
to help reduce the possibility of further
damage due to a secondary collision,
however, that effect changes according
to various conditions. Overly relying on
the system may result in death or serious
injury.

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.224)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.80)
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.

any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
■To protect the windshield wipers
 P.188
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
Park the vehicle and shift the shift posi-
tion to P without setting the parking
brake. The parking brake may freeze
up, preventing it from being released. If
the vehicle is parked without setting
the parking brake, make sure to block
the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly leading to
an accident.
Tire chains cannot be mounted.
Snow tires should be used instead.
To enable the windshield wipers to be
lifted when heavy snow or icy condi-
tions are expected, change the rest
position of the windshield wipers from
the retracted position below the hood
to the service position using the wiper
lever. ( P.189)
