Sensor detection information
Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A 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 sensors in the
vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather
• A non-genuine Lexus suspension (lowered suspension etc.) is
installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
The shape of the obstacle may prevent a sensor from detecting it. Pay
particular 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 projecting outwards in the direction
of your vehicle

Hill-start assist control
Hill-start assist control operating conditions
The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
Hill-start assist control cannot be operated while the slip indicator light
is illuminated.
Hill-start assist control helps to prevent the vehicle from rolling back-
wards when starting on an incline or slippery slope.
To engage hill-start assist
control, further depress the
brake pedal when the vehicle
is stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

Hill-start assist control
While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicle to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control buzzer
When hill-start assist control is activated, the buzzer will sound once.
In the following situations, hill-start assist control will be canceled and
the buzzer will sound twice.
• No attempt is made to drive the vehicle within approximately 2 sec-
onds of releasing the brake pedal.
• Push the P position switch.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3
minutes.
If the slip indicator comes on
It may indicate a malfunction in the system. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.

CAUTION
Hill-start assist control
Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on extremely steep inclines or roads covered in 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 vehicle on an incline for an
extended period of time, as doing so may lead to an accident.

Before driving the vehicle
Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that
is frozen. Pour warm water over the frozen area to melt the
ice. Wipe away the water immediately to prevent it from
freezing.
To ensure proper operation of the climate control system
fan, remove 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 accumulated 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.
When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between
you and the vehicle ahead, and drive at a reduced speed suit-
able to road conditions.
When parking the vehicle
Park the vehicle and shift the shift position to P and block the
wheel under the vehicle without setting the parking brake.
The parking brake may freeze up, preventing it from being

CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the size specified.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden turns and braking, as use of chains may adversely affect
vehicle handling.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move
unexpectedly, possibly resulting in an accident.

CAUTION
When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
When using a floor jack, follow the instructions of the manual provided
with the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
Do not start the hybrid system while the vehicle is supported by the floor
jack.
Stop the vehicle on level, firm ground, firmly set the parking brake and
shift the shift position to P.
Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
Do not raise the vehicle while someone is in the vehicle.
When raising the vehicle, do not place any object on top of or underneath
the floor jack.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
