How to use the camera ●
The parking assist monitor may not oper ate 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, disassemble or
modify it. This may cause incorrect operation.
• When cleaning the camera lens, flush the camera with a large quantity of water,
rinse the camera lens with water and wipe it with a soft and wet cloth. Failure to do
so may cause the camera lens to be scratched and unable to 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 vehi-
cle 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 malfunctioning.
• When the camera is used under fluorescen t lights, sodium light or mercury light
etc., the lights and the illuminate d areas may appear to flicker.●
Do not expose the camera to strong impa ct as this could cause a malfunction.
If this happens, have the vehicle inspected by your Lexus dealer as soon as possible.

Driving
NX300h_U_OM78007U ◆ Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆ Highway driving
Control and maintain the vehicle at a co nstant 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.
◆ 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 th e 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. Also, fuel con-
sumption 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 amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use ti res that are appropriate for the season.
◆ Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will 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 repeated ly warm up, which can lead to excess
fuel consumption.

NX300h_U_OM78007UWinter 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 the condition of the 12-volt battery. ●
Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the front tires
* . Ensure that all tires are the same size and br and, and that chains match the size of the
tires.
* : Tire chains cannot be mounted on the 225/60R18 tires.
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 imme-
diately 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.Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.

NX300h_U_OM78007UUtility vehicle precautions ●
Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feat ure causes this type of vehicle to be
more likely to rollover. Utility vehicles have a significantly higher rollover rate
than other types of vehicles. ●
It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars designed to perform satisfactorily under
off-road conditions. Therefore, shar p turns at excessive speeds may cause
rollover.This vehicle belongs to the utility vehicl e class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity.

Utility vehicle precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle: ●
In a rollover crash, an unbelted person is si gnificantly more likely to die than a person
wearing a seat belt. Therefore, the driver and all passengers should always fasten
their seat belts. ●
Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may re sult in loss of control or vehicle rollover
causing death or serious injury. ●
Loading cargo on the roof luggage carrier (i f equipped) will make the center of the
vehicle gravity higher. Avoid high speeds, su dden starts, sharp turns, sudden braking
or abrupt maneuvers, otherwise it may result in loss of control or vehicle rollover due
to failure to operate this vehicle correctly. ●
Always slow down in gusty crosswinds. Be cause of its profile and higher center of
gravity, your vehicle is more sensitive to side winds than an ordinary passenger car.
Slowing down will allow you to have better control. ●
Do not drive horizontally across steep slopes . Driving straight up or straight down is
preferred. Your vehicle (or any similar off-road vehicle) can tip over sideways much
more easily than forward or backward.
