■How to use the camera
●The rear view monitor system may not operate properly in the following cases, or
if the precautions described below are not followed.
• If the back of the vehicle is hit, the position and mounting angle of the cameramay change.
• As the camera has a water proof construction, do not detach, disassemble 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 cam- era or camera area. Doing so may result in the camera malfunctioning.
• When the camera is used under fluorescent lights, sodium light or mercury 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 malfunction. If
this happens, have the vehicle inspected by your Lexus dealer as soon as possi-
ble.

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

■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 6 )
■Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of Hybrid
System Indicator within Eco area. ( P. 9 2 )
■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:

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.
