( P.229)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be re duced, the windows
may become fogged-u p, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of water between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden
acceleration.
●The vehicle is judged to be driving uphill
or downhill
●When the accelerato r pedal is released
●When the brake pedal is depressed while
Driving the vehicle
The following procedures should be
observed to ensure safe driving:
Driving procedure

1224-1. Before driving
WARNING
●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
effectiveness. (
P.134)
●Do not adjust the positions of the
steering wheel, the seat, or the inside
or outside rear view mirrors while driv-
ing.
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 across a river 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 per-
mits 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 sur-
faces
●Sudden braking, acceleration and
steering may cause tire slippage and
reduce your ability to control the vehi-
cle.
●Sudden acceleration, engine braking
due to shifting, or changes in engine
speed could cause the vehicle to skid.
●After driving through a puddle, lightly
depress the brake pedal to make sure
that the brakes are functioning prop-
erly. Wet brake pads may prevent the
brakes from functioning properly. If the
brakes on only one side are wet and
not functioning properly, steering con-
trol may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward
while the shift lever is in a driving posi-
tion, or roll forward while the shift lever
is in R.
Doing so may cause the engine to stall
or lead to poor brake and steering
performance, resulting in an accident
or damage to the vehicle.
●Do not shift the shift lever to P while
the vehicle is moving.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●Do not shift the shift lever to R while
the vehicle is moving forward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●Do not shift the shift lever to a driving
position while the vehicle is moving
backward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●Shifting the shift lever to N while the
vehicle is moving will disengage the
engine from the transmission. Engine
braking is not available when N is
selected.
●Be careful not to shift the shift lever
with the accelerator pedal depressed.
Shifting the shift lever to a gear other
than P or N may lead to unexpected
rapid acceleration of the vehicle that
may cause an accident and result in
death or serious injury.

1244-1. Before driving
WARNING
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated area,
exhaust gases may collect and enter the
vehicle, leading to death or a serious
health hazard.
■When braking
●When the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle.
●If the brake booster device does not
operate, do not follow other vehicles
closely and avoid hills or sharp turns
that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will increase. Have your
brakes fixed immediately.
●Do not pump the brake pedal if the
engine stalls.
Each push on the brake pedal uses up
the reserve for the power-assisted
brakes.
●The brake system consists of 2 individ-
ual hydraulic systems; if one of the sys-
tems fails, the other will still operate. In
this case, the brake pedal should be
depressed more firmly than usual and
the braking distance will increase.
Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when
any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and
brake pedals at the same time during
driving, as this may restrain the engine
output.
●Do not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill.
■When parking the vehicle
Always set the parking brake and shift
the shift lever to P. Failure to do so may
cause the vehicle to move or the vehicle
may accelerate suddenly if the accelera-
tor pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in
either direction and hold it there for an
extended period of time.
Doing so may damage the power
steering motor.
●When driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
●IS300: Make sure to idle the engine
immediately after high-load driving.
Stop the engine only after the
turbocharger has cooled down.
Failure to do so may cause damage to
the turbocharger.

after heavy rain etc. Doing so may cause
the following serious damage to the vehi-
cle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a flooded
road and the vehicle is flooded, be sure
to have your Lexus dealer check the fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis-
sion, transfer (AWD models), differen-
tials, etc.
●Lubricant condition for the propeller

1484-3. Operating the lights and wipers
●The high beams may be turned off if a
vehicle ahead that is using fog lights with-
out its headlights turned on is detected.
●House lights, street lights, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.
●The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera-
tional lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of th e road surface, etc.)
• The number of passengers and amount of
luggage in the vehicle
●The high beams may turn on or off unex-
pectedly.
●Bicycles or similar vehicles may not be
detected.
●In the following situations the system may
not be able to correctly detect the sur-
rounding brightness level. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually switch between the high
and low beams.
• When driving in inclement weather (heavy rain, snow, fo g, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or dam-
aged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equal to that of head lights, tail lights or
fog lights
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of inter- mittently changing brightness and dark-
ness
• When frequently and repeatedly driving
ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,
etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object
ahead of the vehicle, such as a sign or
mirror
• When the back of a preceding vehicle is
highly reflective, such as a container on a
truck
• When the vehicle’s headlights are dam-
aged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams
repeatedly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling
pedestrians or other drivers
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the engine switch off while the fol-
lowing conditions are met.
●The headlight switch is in or .
●The headlight switch lever is in the origi-
nal position.
●Automatic High Beam switch is on.
2 Turn the engine switch to IGNITION
ON mode.
3 Within 60 seconds after step 2, repeat
pushing the headlight switch lever to the
high beam position then pulling it to the
original position quickly 10 times, then

WARNING
• Conditions under which the system may not operate properly:
P.172
●Do not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.
●If the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seco nds. Depress the
brake pedal as necessary.
●The pre-collision braking function may
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and pos-
sibly prevent the pre-collision braking
function from operating.
●In some situations, while the pre-colli-
sion braking function is operating,
operation of the function may be
canceled if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
●If the brake pedal is being depressed,
the system may determine that the
driver is taking evasive action and pos-
sibly delay the operation timing of the
pre-collision braking function.
■Emergency steering assist
●As emergency steering assist opera-
tion will be canceled when the system
determines that lane departure pre-
vention function ha s been completed.
●Emergency steering assist may not
operate or may be ca nceled in the fol-
lowing cases as the system may deter-
mine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering wheel
is being operated sharply, the brake
pedal is being depressed or the turn
signal lever is being operated. In this
case, the system may determine that
the driver is taking evasive action and
the emergency steeri ng assist may not
operate.
• In some situations, while the emer- gency steering assist is operating,
operation of the function may be
canceled if the ac celerator pedal is
depressed strongly, the steering wheel
is operated sharply or the brake pedal
is being depressed and the system
determines that the driver is taking
evasive action.
• When the emergency steering assist is operating, if the steering wheel is held
firmly or is operated in the opposite
direction to that which the system is
generating torque, the function may be
canceled.
■When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another
vehicle
●When transporting the vehicle via
truck, boat, train or similar means of
transportation

1684-5. Using the driving support systems
■Enabling/disabling the pre-colli-
sion system
The pre-collision system can be
enabled/disabled on ( P.75) of
the multi-information display.
The system is automa tically enabled each
time the engine switch is turned to IGNI-
TION ON mode.
If the system is disabled, the PCS warn-
ing light will turn on and a message will
be displayed on the multi-information
display.
■Changing the pre-collision warn-
ing timing
The pre-collision warning timing can
be changed on ( P.75) of the
multi-information display.
The warning timing setting is retained
when the engine switch is turned off. How-
ever, if the pre-collision system is disabled
and re-enabled, the operation timing will
return to the default setting (middle).
If the pre-collision warning timing is
changed, emergency steering assist
timing will also be changed accord-
ingly.
If late is selected, emergency steering
assist would not operate in case of an
emergency.
