NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, 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. 545, 559)
■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 pro-
fessional check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, hybrid transmis-
sion, differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

IS300h_EE(OM53D56E)4-6. Driving tips
■Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system (heating/
cooling) will be minimized, improving the fuel economy. (
→P. 2 9 3 )
■Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicator needle (except F
SPORT models) or bar display (F SPORT models) of Hybrid System Indicator
within the Eco area. ( →P. 1 1 3 )
■When braking
Make sure to operate the brakes gently and in good time. A greater amount
of electrical energy can be regenerated when slowing down.
■Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When driving in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
■Highway driving
Control your speed and keep at a constant speed. Before stopping at a toll
booth or similar, allow plenty of time to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following points:

Maintenance and care
IS300h_EE(OM53D56E)
Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and the
tire.
When resting the tire on the ground,
place the tire so that the wheel design
faces up to avoid scratching the wheel
surface.

CAUTION
■Replacing a tire
Observe the following precautions to reduce the risk of death or serious injury.
●Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5 kgf•m, 76
ft•lbf) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and the wheel may
fall off, which could lead to an accident causing death or serious injury.
●Do not attach a heavily damaged wheel orname nt, as it may fly off the wheel while the
vehicle is moving.

4807-3. Do-it-yourself maintenance
IS300h_EE(OM53D56E)
Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen
while the vehicle is in motion, causing
the tire to come off.
Install the spare tire and loosely tighten each wheel nut by hand by approxi-
mately the same amount.
Turn the wheel nuts until the washers
come into contact with the disc
wheel.
Lower the vehicle.
Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
Tightening torque:
103 N•m (10.5 kgf•m, 76 ft•lbf)
Stow the jack and all tools.
