For efficient use
Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will discharge, requiring unnecessary
engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decelera-
tion will make more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power, result-
ing in poor acceleration. Battery power can be restored by driving with the
accelerator pedal slightly released.
Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may dis-
charge the hybrid battery (traction battery). The vehicle cannot be driven if the
hybrid battery (traction battery) is discharged.

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the brake and accelera-
tor pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal
will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty
in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay response in an emergency, resulting in an
accident.
The driver should pay extra attention to pedestrians when the vehicle is pow-
ered only by the electric motor (traction motor). As there is no engine noise,
the pedestrians may misjudge the vehicle’s movement.
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts
may cause a fire if there is any flammable material nearby.
During normal driving, do not turn off the hybrid system. Turning the hybrid
system 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. 499
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. 216)
Do not adjust the positions of the steering wheel, the seat, or the inside or out-
side 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.
1964-1. Before driving
IS300h_EE(OM53B95E)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle.
Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid.
After driving through a puddle, 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 function-
ing properly, steering control may be affected.
When shifting the shift lever
Do not let the vehicle roll backward while the shift lever is in D or S, or roll
forward while the shift lever is in R.
Doing so may result 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 D 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
hybrid system. 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.
If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional as soon as possi-
ble.
Rotor damage may result if the pads are not replaced when needed.
Moderate levels of brake pad and disc wear allow enhanced braking power. As
a result, the discs may wear more quickly than conventional brake discs. There-
fore, when replacing the brake pads, Lexus recommends that you also have the
thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/
or those of the brake discs are exceeded.

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.

Tire information
Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater
than the recommended value when towing. (P. 570)
Increase the air pressure of the trailer tires in accordance with the total trailer
weight and according to the values recommended by the manufacturer of your
trailer.
Break-in schedule
Lexus recommends that vehicles fitted with new power train components should
not be used for towing trailers for the first 800 km (500 miles).
Safety checks before towing
Check that the maximum load limit for the towing hitch/bracket hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the
load exerted on the vehicle. Also make sure that you will not be towing a load
that exceeds the maximum permissible axle capacity.
Ensure that the trailer load is secure.
Supplementary outside rear view mirrors should be added to the vehicle if the
traffic behind cannot be clearly seen with standard mirrors. Adjust the extend-
ing arms of these mirrors on both sides of the vehicle so that they always pro-
vide maximum visibility of the road behind.
Maintenance
Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle compared to nor-
mal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that area.
When steel and aluminum come into contact, there is a reaction similar to cor-
rosion, which will weaken the section concerned and may result in damage.
Apply a rust inhibitor to parts that will come in contact when attaching a steel
bracket.
