2-1. Driving procedures
HS250h_U_75033U(Canada)
CAUTION
●Do not select shift position R when the vehicle is rolling forward, do not select D
when moving in reverse, and do not press the P position switch before the vehicle
stops fully. Doing so will cause the buzzer to sound and the shift position to
change to N. In addition, excessive force will be applied to the powertrain and
damage may result.
●Do not change the shift position to N while the vehicle is moving.
Doing so may cause insufficient engine braking, resulting in an accident.
●Do not turn the hybrid system off while driving.
The power steering and brake actuator will not operate properly if the hybrid sys-
tem is off.
●Use engine braking (shift position B) to maintain a safe speed when driving down
a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (→P. 1 5 3 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their body are not
outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Abrupt changes from shift position D to B and rapid changes in the engine speed
could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.

When driving

●The following factors may affect the amount of time taken to turn high beam on
or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and pre-ceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage
●High beam may be turned on or off when unexpected by the driver.
●In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beams on or off
manually rather than relying on the Automatic High Beam System.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are chang-
ing color, or have are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads,
gravel tracks etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead of the vehicle, such as a sign or a mir- ror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.

2-3. Operating the lights and windshield wipers
HS250h_U_75033U(Canada)
■If the Automatic High Beam indicator flashes
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Temporary lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
To lower the sensitivity, push and hold the “AUTO” button on the inside rear view
mirror for 15 to 20 seconds, and release. The indicator light on the inside rear view
mirror will flash to indicate that the sensitivity has been lowered.
When the “POWER” switch is turned off, the sensitivity will be returned to its nor-
mal level.
■Customization that can be configured at your Lexus dealer
The Automatic High Beam can be turned off.

NOTICE
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if necessary.
■Notes when using the Automatic High Beam system
●Do not touch the camera sensor.
●Do not subject the inside rear view mirror or the camera sensor to a strong
impact.
●Do not disassemble the camera sensor.
●Do not spill liquid onto the inside rear view mirror or the camera sensor.
●Do not apply window tinting or stickers to the camera sensor or the area of wind-
shield near the camera sensor.
●Do not place items on the dashboard. There is a possibility that the camera sensor
will mistake items reflected in the windshield for streetlights, the headlights of
other vehicles, etc.
●Do not install a parking tag or any other accessories near or around the inside
rear view mirror and the camera sensor.
●Do not overload the vehicle.
●Do not modify the vehicle.
●Do not replace windshield with non-genuine windshield.
Contact your Lexus dealer.

2-4. Using other driving systems
HS250h_U_75033U(Canada)
NOTICE
■Camera sensor
●Keep the windshield clean at all times.
LKA performance may deteriorate due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
●Do not attach a sticker or other items to the windshield near the camera sensor.
●When adjusting the rear-view mirror, make sure that it does not block the camera
lens.
●When it is cold, using the heater with air blowing to the feet may allow the upper
part of the windshield to fog up. This will have a negative effect on the images. In
such a case, use the windshield defogger to provide warm, dry air to the wind-
shield.
●Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield as lane
markers by mistake.
●Do not scratch the camera lens, or let it get dirty.
●Do not change the installation position of the camera sensor or remove it. The
direction of the camera sensor is precisely adjusted.
●Do not subject the camera sensor to strong impact or force, and do not disas-
semble the camera sensor.
Observe the following to ensure that the LKA
system functions correctly.
