■To prevent sensor error
CAUTION
■Caution while driving
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and an accident, resulting in death
or serious injury.
In automatic mode, sensors are used to detect the headlights of vehicles
behind and automatically reduce the reflected light.
Turns automatic mode on/off
The indicator comes on when
automatic mode is turned on.
The anti-glare mirror default
mode is automatic. The anti-
glare mirror is automatically set

■Linked mirror function when reversing (vehicles with driving position memory)
The outside rear view mirrors will automatically angle downwards when the vehicle
is reversing in order to give a better view of the ground. However, this function will
not operate when the mirror select switch is in the neutral position (between “L” and
“R”).
■Auto anti-glare function (vehicles with sports or luxury package)
When the anti-glare inside rear view mirror is set to automatic mode, the outside
rear view mirrors will activate in conjunction with the anti-glare inside rear view mir-
ror to reduce reflected light. (
P. 6 5 )
■Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it rains, the
rain clearing (hydrophilic) effect of the mirrors causes the droplets to be spread out
into a film making the rear view clearer.In the following cases, the rain clearing
effect will be reduced temporarily, but will return after 1 or 2 days' exposure to
direct sunlight.
●After wiping dirt off the mirrors
●When the mirrors fog up
●After waxing your vehicle in an automatic car wash
●After your vehicle has been parked for a long period in underground parking
lots, etc. where there is no direct sunlight.

CAUTION
■When driving the vehicle
Observe the following precautions while driving.
Failing to do so may result in loss of control of the vehicle and cause an accident,
resulting in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded back.
●Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot and burn
you.
NOTICE
■If the mirrors become iced up
In order to retain the rain-clearing properties of the mirror, do not attempt to scrape
the ice off. Instead, remove it by turning on the mirror defoggers or by applying
warm water.

2-1. Driving procedures
08_IS350/250_U_(L/O_0808)
CAUTION
●Do not turn the engine off while driving.
The power steering and brake booster system will not operate properly if the
engine is not running.
●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 3 2 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Do not adjust the position 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 that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive the vehicle off-road.
This is not a AWD vehicle designed for real off-road driving. Proceed with all due
caution if it becomes unavoidable to drive off-road.
●Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage the
engine or cause other serious damage to 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.

When driving
08_IS350/250_U_(L/O_0808)
■Rain drop sensor (vehicles with the rain-sensing windshield wipers)
■Outside rear view mirror defogger activation linked to windshield wiper opera-
tion
The outside rear view mirror defogger automatically turns on when you operate the
windshield wipers.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Customization that can be configured at Lexus dealer
Settings (e.g. drip prevention function) can be changed.
(Customizable features
P. 4 6 1 )
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers or
anything else do not become caught in the windshield wipers.
The sensor judges the amount of raindrops.
