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
and wipe it with a soft and wet cloth. St rongly rubbing the camera lens 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.

●
Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid ●
Have a service technician inspect the condition of the 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 of the specified size and the same brand, and that chains
match the size of the 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.Winter driving tips 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.

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. And, utility vehicles have a significantly higher rollover
rate than other types of vehicles. ●
An advantage of the higher ground clearance is a better view of the road
allowing you to anticipate problems. ●
It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.Utility vehicle precautions 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, 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 w ill make the center of the vehicle gravity
higher. Avoid high speeds, sudden 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.

●
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 thoroughly 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. ■
Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc. ●
The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.●
The restoration time differs depending on the depth of the scratch and outside temper-
ature. The restoration time may become shor ter when the coating is warmed by apply-
ing warm water. ●
Deep scratches caused by keys, coins, etc. cannot be restored.●
Do not use wax that contain abrasives. ■
Automatic car washes ●
Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door
Start washing from the front of the vehicle. Extend the mirrors before driving. ●
Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint. ●
Rear spoiler 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 prop-
erly.Cleaning and protecting the vehicle exterior Perform the following to protect the ve hicle and maintain it in prime condi-
