NOTICE
When driving the vehicle
Do not depress the accelerator and brake pedals at the same time during driv-
ing, as this may restrain driving torque.
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 shift the shift lever to P. Failure to do so may cause the vehicle to move
or the vehicle may accelerate suddenly if the accelerator 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.
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.
Information on what to do in case of a flat tire (P. 530, 544)
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
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 any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional check the following:
Brake function
Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, differential, etc.
Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible), and the function of all joints, bearings, etc.

Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect the condition of the 12-volt battery.
Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains match
the size of the tires.
*: Tire chains cannot be mounted on the 18-inch tires.
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 accumu-
lated 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 get-
ting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the

CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may cause
skin disorders such as inflammation and skin cancer, so care should be taken
to avoid prolonged and repeated contact. To remove used engine oil from
your skin, wash thoroughly with soap and water.
Dispose of used oil and filters only in a safe and acceptable manner. Do not
dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information con-
cerning recycling or disposal.
Do not leave used engine oil within the reach of children.
NOTICE

IS300h_EE(OM53B95E)
CAUTION
Replacing light bulbs
Turn off the lights. Do not attempt to replace the bulb immediately after turn-
ing off the lights.
The bulbs become very hot and may cause burns.
Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth to
avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This may
damage the headlights or cause condensation to build up on the lens.
Discharge headlights (if equipped)
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional before replacing the discharge headlights (including
light bulbs).
Do not touch the discharge headlight’s high voltage socket when the head-
lights are turned on.
An extremely high voltage of 30000 V will be discharged and could result in
death or serious injury by electric shock.
Do not attempt to take apart or repair the headlight bulbs, connectors, power
supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
To prevent damage or fire
Make sure bulbs are fully seated and locked.
Check the wattage of the bulb before installing to prevent heat damage.
Vehicles with discharge headlights: While
the headlights are turned on, and for a
short time after they have been turned off,
metal components at the rear of the head-
light assembly will be extremely hot. To
prevent burns, do not touch these metal
components until you are certain they
have cooled down.
