NOTICE
How to use the camera
The parking assist monitor may not operate properly in the following
cases.
• If the back of the vehicle is hit, the position and mounting angle of the
camera may change.
• As the camera has a water proof construction, do not detach, disassem-
ble or modify it. This may cause incorrect operation.
• Do not strongly rub the camera lens. If the camera lens is scratched, it
cannot transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on
the vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunction-
ing.
• When the camera is used under fluorescent lights, sodium light or mer-
cury light etc., the lights and the illuminated areas may appear to
flicker.
Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible.

the accelerator and gently apply the brakes. A greater amount of
electrical energy can be retained when slowing down.
Air conditioning
Use the air conditioning only when necessary. Doing so can help
control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, 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 inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeat-
edly warm up, which can lead to poor fuel consumption.

Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle’s roof, chassis, around
the tires or on the brakes.
Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to road
conditions.
Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If necessary, block the wheels to prevent inadver-
tent sliding or creeping.

When using the microphone
It is unnecessary to speak directly into the microphone when giving a com-
mand.
Wait for the confirmation beep before speaking a command.
Speech commands may not be recognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while speech commands are spoken.
• The air conditioning speed is set high.
• The air conditioning vents are turned towards the microphone.
In the following conditions, the system may not recognize the command
properly and using speech commands may not be possible:
• The command is incorrect or unclear. Note that certain words, accents or
speech patterns may be difficult for the system to recognize.
• There is excessive background noise, such as wind noise.
When searching for a track
A USB memory or iPod must be connected to enable track searching and
playback. (P. 579, 590)
When a USB memory or iPod is connected, recognition data is created so
tracks can be searched using speech commands.
Recognition data is updated under the following conditions:
• When the USB memory or iPod data has changed.
• When the voice recognition language is changed. (P. 456)
While the recognition data is being created or being updated, a track search
cannot be performed using a speech command.
When “Play music” is dimmed in the “Shortcuts” screen, it is not possible
to search for a track using a speech command. In this situation, reduce the
amount of music data in the USB memory or iPod and update the recogni-
tion data to enable searching by speech command.

7206-1. Maintenance and care
GS450h_300h_OM_OM30D53E_(EE)
Cleaning and protecting the vehicle exterior
Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any
dirt and dust.
Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
Wipe away any water.
Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
Automatic car washes
Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
Rear spoiler (if equipped) may not be washable in some automatic car
washes. There may also be an increased risk of damage to vehicle.
High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity of
the windows.
Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
Perform the following to protect the vehicle and maintain it in
prime condition:
