To drive using temporary shift range selection, operate the “-” paddle shift switch.
Changing the shift range enables the level of engine braking force to be
selected. The shift range can then be selected by operating the “-” and “+” paddle
shift switches.
Upshifting
Downshifting
The selected shift range, from D1 to D6,
will be displayed in the meter.
The initial shift range when the “-” pad-
dle shift switch is operated is automati-
cally set to D2, D3, D4 or D5 according
to the vehicle speed.
To return to normal D position driving,
the “+” paddle shift switch must be held
down for a period of time.
■Shift ranges and their functions
●You can choose from 6 levels of engine braking force.
●A lower shift range will provide greater engine braking force than a higher
shift range, and the engine revolutions will also increase.

■When the “-” paddle shift switch is operated with the shift lever in the D position
The shift range is downshifted to a range that enables engine braking force that is suit-
able to driving conditions.
■Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●When the shift lever is shifted to a position other than D
■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circumstances, downshifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the power switch is turned off after driving in
snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●While driving in D or S mode, downshifting to 5 or 4. (→P. 245, 249)
●When switching the driving mode to sport mode while driving in D position. (→P. 2 8 3 )

CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction battery) will not be charged even
when the engine is running. Therefore, if the vehicle is left with the shift lever in N for a
long period of time, the hybrid battery (traction battery) will discharge, and this may
result in the vehicle not being able to start.

■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s front corner
and rear bumpers.
●Certain vehicle conditions and the surrounding environment may affect the ability of
the sensor to correctly detect obstacles. Particular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape,
signs and other objects may be judged by the sensor to be closer than they are.
●The shape of the obstacle may prevent the sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow
speeds, there is a possibility that the obstacle will come within the sensor’s detection
areas before the display is shown and the warning beep sounds.
• Thin posts or objects lower than the sensor may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow
noise of the air conditioning system.

■When the 12-volt battery is disconnected
The steering wheel may move from its straight forward position, but this will be corrected
automatically when driving.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC, hill-start assist con-
trol systems
●A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the hybrid system is started or just after the vehicle begins
to move. This sound does not indicate that a malfunction has occurred in any of these
systems.
●Any of the following conditions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■EPS operation sound
When the steering wheel is operated, a motor sound may be heard. This does not indi-
cate a malfunction.
■Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the hybrid system off and
then on again will automatically reactivate the TRC/VSC systems.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when vehicle speed
increases. However, when both TRC and VSC systems are turned off, the systems will
not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering
wheel may feel heavy as a result. Should this occur, refrain from excessive steering input
or stop the vehicle and turn the hybrid system off. The EPS system should return to nor-
mal within 10 minutes.

3104-6. Driving tips
IS300h_EE(OM53C61E)
■Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out until it
and the interior of the vehicle are warm, it will consume fuel. Fuel consumption
can be improved by avoiding overuse of the heater.
■Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on dry roads
can lead to poor fuel economy. Use tires that are appropriate for the season.
■Luggage
Carrying heavy luggage can lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack can also cause poor fuel
economy.
■Warming up before driving
Since the gasoline engine starts up and cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeatedly warm up, which can lead to excess
fuel consumption.
