4-1. Before driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
●During normal driving, do not turn off the engine. Turning the engine off while
driving will not cause loss of steering or braking control, but the power assist to
these systems will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: →P. 6 7 7
●Use engine braking (downshift) 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 7 8 )
●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.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.
●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.

NOTICE
■To prevent damage to or incorrect operation of the LKA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension or sun visor, or replace them with non-genuine
parts.
●Do not install or place anything on the hood or the grille. Also, do not install a
grille guard (bull bars, kangaroo bar etc.).
●Do not modify the sun visor or replace it with anything other than a genuine
Lexus product.
●If your windshield needs repairs, contact your Lexus dealer.
■Camera sensor (→P. 228)
Observe the following to ensure that the LKA system functions correctly.
●Keep the windshield clean at all times.
Performance could be affected if the windshield is dirty, or if raindrops, conden-
sation or ice are adhering to the windshield.
●When adjusting the rear view mirror, make sure that it does not block the camera
lens.
●Do not attach window tinting to the windshield.
●Do not install an antenna in front of the camera lens.
●If the windshield is fogged up, use the windshield defogger to remove fog from
the windshield.
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.

CAUTION
■When using the rear view monitor system
When backing up, be sure to check visually behind and all around the vehicle
before proceeding.
Observe the following precautions to avoid an accident that could result in death
or serious injuries.
●The rear view monitor system is a supplemental device intended to assist the
driver when backing up. Never depend on the rear view monitor system entirely
when backing up. Always make sure your intended path is clear.
Use caution, just as you would when backing up any vehicle.
●Never back up while looking only at the screen.
The image shown on the screen may differ from the actual state, and you could
collide with another vehicle or obstacles if backing up looking only at the screen,
possibly causing an accident. When backing up, be sure to check in front of and
behind the vehicle, both directly and with mirrors.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traffic con-
ditions, road surface conditions, vehicle condition, etc. when parking. It is neces-
sary to be fully aware of this before using the rear view monitor system.
●When parking, be sure to check that the parking space will accommodate your
vehicle before maneuvering into it.
●Do not use system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the trunk lid is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to
see the image on the screen. Be sure to check direct visually and with mirror all
around the vehicle before proceeding.
●If the tire sizes are changed, the position of the fixation guide lines displayed on
the screen may change.
●The camera uses a special lens. The distances between objects and pedestrians
that appear in the image displayed on the screen will differ from the actual dis-
tances. (→P. 2 5 4 )

BSM (Blind Spot Monitor)∗
∗: If equipped
The Blind Spot Monitor is a system that assists the driver to confirm
safety when changing lanes.
The system uses radar sensors to d etect vehicles that are traveling in an
adjacent lane in the area that is not reflected in the outside rear view
mirror (the blind spot), and advises the driver of the vehicles existence
via the outside rear vi ew mirror indicator.
BSM main switch
Pressing the switch turns the system on or off. When the switch is set to on, the
switch’s indicator illuminates.
Outside rear view mirror indicator
When a vehicle is detected in the blind spot, the outside rear view mirror indica-
tor on that side illuminates. If the turn signal lever is operated when a vehicle is in
the blind spot, the outside rear view mirror indicator flashes.

• When driving on a road surface that is wet due to rain, standing water etc.
• When there is a significant difference in speed between your vehicle and thevehicle that enters the detection area
• When a vehicle is in the detection area from a stop and remains in the detection area as your vehicle accelerates
• When driving up or down consecutive steep inclines, such as hills, a dip in the road etc.
• When multiple vehicles approach with only a small gap between each vehicle
• When vehicle lanes are wide, and the vehicle in the next lane is too far away from your vehicle
• When the vehicle that enters the detection area is traveling at about the same speed as your vehicle
• When there is a significant difference in height between your vehicle and the vehicle that enters the detection area
• Directly after the BSM switch is set to on
●Instances of the Blind Spot Monitor unnecessarily detecting a vehicle and/or object
may increase under the following conditions:
• When there is only a short distance between your vehicle and a guardrail, wall etc.
