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.

IS300h_EE(OM53B95E)4-6. Driving tips
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelera-
tor 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 econ-
omy. (P. 290)
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 4 )
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 leav-
ing and avoid delays as much as possible. When driving in a traffic
jam, gently release the brake pedal to allow the vehicle to move for-
ward slightly while avoiding overuse 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(OM53B95E)
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 ornament, as it may fly off the wheel
while the vehicle is moving.

4647-3. Do-it-yourself maintenance
IS300h_EE(OM53B95E)
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel con-
tact 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
approximately 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.
