After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move. For safety, apply the parking brake and make sure to shift the shift lever to
P when parked.
The following sounds or vibrations may occur when the hybrid system is operat-
ing and are not a malfunction:
Motor sounds may be heard from under the vehicle.
Sounds may be heard from the hybrid battery (traction battery) behind the rear
seats when the hybrid system starts or stops.
Sounds from the hybrid system may be heard when the trunk lid is open.
Sounds may be heard from the hybrid transmission when the hybrid system
starts or stops.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal is
depressed.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vents on the both sides of
the rear seatback.
Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional regarding maintenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.

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.

Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when moving
alongside such vehicles. As soon as such vehicle movement occurs,
immediately start to decelerate smoothly by slowly applying the
brakes. Always steer the vehicle straight ahead while braking.
Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before execut-
ing lane changes.
Transmission information
To maintain engine braking efficiency, when using engine braking
when driving on a long steep downward grade, do not use the transmis-
sion in D. The vehicle must be driven in gear shift position “4” in S
mode. (P. 219)
If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures exceed-
ing 30C (85F) may result in the engine overheating. If the engine
coolant temperature gauge indicates that the engine is overheating, turn
the air conditioning off immediately, leave the road and stop the vehi-
cle in a safe place.
(P. 555)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and
trailer. Firmly set the parking brake and shift the shift lever to P.

2164-2. Driving procedures
IS300h_EE(OM53B95E)
While the power switch is in ON mode, move the shift lever with the
brake pedal depressed.
When shifting the shift lever between P and D, make sure that the vehicle is
completely stopped.

IS300h_EE(OM53B95E)8-2. Steps to take in an emergency
The following may indicate a problem with your transmission. Contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional before towing.
The hybrid system is operating but the vehicle will not move.
The vehicle makes an abnormal sound.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing eyelet. This should only be
attempted on hard surfaced roads for
short distances at under 30 km/h (18
mph).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in good
condition.
If your vehicle needs to be towed
If towing is necessary, we recommend having your vehicle towed by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional or a commercial towing service, using a lift-type
truck or flat bed truck.
Use a safety chain system for all towing, and abide by all state/provincial
and local laws.

CAUTION
When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding area is clear to avoid striking other vehicles, objects or people. The
vehicle may also lunge forward or lunge back suddenly as it becomes free. Use
extreme caution.
When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident resulting in death or serious injury.
NOTICE
To avoid damaging the transmission and other components
Avoid spinning the rear wheels and depressing the accelerator pedal more
than necessary.
If the vehicle remains stuck even after these procedures are performed, the
vehicle may require towing to be freed.
