CAUTION
■Before using the Lexus night view
Never depend on this system only.
Lexus night view is intended as a supplemental aid to help you see pedestrians and
road conditions ahead of the vehicle. As there are limits to the system, do not rely
solely on the system while in use, and drive safely while observing the following
precautions.
■When using the Lexus night view
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Never drive while looking at the Lexus night view screen only.
●Do not look continuously at the Lexus night view screen while driving. Pedestri-
ans, objects etc. ahead of the vehicle may be overlooked by the system. The sys-
tem should always be used as a supplemental aid only.
●Lexus night view is designed to help you see objects better when driving in dark-
ness on a road with few curves. Do not use the Lexus night view in well-lit areas or
on roads with many curves or slopes. There may be areas that cannot be dis-
played by the system due to the road conditions (curve size, gradient, etc.)
●Lexus night view may be unable to project some features at an appropriate level
of brightness. Some or all parts of certain features may be dark or difficult to see.
Do not rely solely on the Lexus night view, and drive carefully while checking the
surroundings for safety, as you would with a normal vehicle. Also, the following
features and conditions may not be displayed clearly.
Features that are difficult to display:
• Clothing of a pedestrian made of a certai n kind of material (ex. leather jackets)
• The characters on signs and billboards
• The information on road signs
Conditions in which display is difficult:
• Unfavorable weather conditions such as rain, fog, snowfall, snow storms etc.
• There are large puddles of water on the road surface following rainfall
• The area of the front windshield in front of the camera is fogged up, dirty or icy
• The areas around the headlights are covered with ice, snow, mud etc.
• The 12-volt battery voltage is remarkably low
• There are bright lights ahead of the vehicle

NOTICE
■The near-infrared camera
●Make sure the front windshield is kept clean.
●System performance may deteriorate if rain water, condensation or ice adheres
to the camera. If you notice the inner lens of the camera is dirty, the garnish will
have to be replaced. Consult your Lexus dealer.
●Do not subject the camera to strong impacts, or disassemble the camera.
●As the alignment of the camera has been very finely adjusted, do not change or
remove the mounting.
●If the front windshield fogs up, defog the windshield using the front defroster.
●Do not dirty or scratch the camera lens.
●Night view may not function properly if an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to the windshield.
Follow these precautions to avoid damage to
or incorrect operation of the Lexus night
view.

Follow these precautions to avoid damage to
or incorrect operation of the Lexus night
view system
●System performance may deteriorate if the
areas around the headlights are dirty. Clean
the vehicle if it is dirty.
●The near-infrared light irradiates strong
energy not visible to the eyes. Do not stare
at the light at close range for a long time.

Hybrid vehicle driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the acceler-
ator pedal depression amount can be generated more smoothly than it
is in normal conditions. In addition, the operatio n of the air conditioning
system (heating/cooling) will be mini mized, improving the fuel econ-
omy. ( P. 2 8 1 )
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of Hybrid
System Indicator within Eco area. ( P. 9 4 )
◆When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
◆Delays
Repeated acceleration and decelerati on, as well as long waits at traffic
lights, will lead to bad fuel consumption. Check traffic reports before
leaving and avoid delays as much as possible. When encountering a
delay, 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. Also, before stop-
ping at a toll booth or similar, allow plenty of time to release the acceler-
ator and gently apply the brakes. A greater amount of electrical energy
can be retained when slowing down.
For economical and ecological drivin g, pay attention to the following
points:

318
GS450h_OM_OM30E26U_(U)
4-6. Driving tips
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help con-
trol 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 eng ine will not automatically cut out
until the gasoline engine and the interi or 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 consump tion. Use a tire that is appropriate
for the season.
◆Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid car-
rying 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 unne cessary. Moreover, frequently driv-
ing short distances will cause the engine to repeatedly warm up, which
can lead to poor fuel consumption.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside temperatures. • Engine oil
• Engine/power control unit coolant
• Washer fluid
●Have a service technician inspect th e condition of the 12-volt battery.
●Have the vehicle fitted with four sno w tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains match the
size of the tires.
*: Tire chains cannot be mounted on vehicles with front and rear tires of differing
sizes and vehicles with LDH and 19-inch tires.
Carry out the necessary preparati ons and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropriate
to the prevailing weather conditions.

4-6. Driving tips
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
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 wind-
shield.
●Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or on
the brakes.
●Remove any snow or mud from the bo ttom 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 inadvertent sliding or
creeping.
