Minimum projected turning circle & projected course line

Use the minimum projected turn-
ing circle & projected course line
(when displayed) to check the
vehicle’s path with relation to
obstacles.
If the minimum projected turning
circle line (blue) is over the obsta-
cle as shown in the illustration, or
the obstacle falls within the mini-
mum projected turning circle, if
you turn with the minimum possi-
ble turning circle, the vehicle may
collide with the object.
When the projected course line
(yellow) is displayed, be sure to
operate the steering wheel so
that the obstacle stays outside the
projected course line until the
vehicle has passed the object.

CAUTION

■

When using the Multi-terrain Monitor system
Observe the following precautions to avoid an accident that could result in death or

serious injuries:

●

When attempting to use the side cameras while the door mirror is folded in, the base

of the door mirror is displayed on the screen and the area in front of the vehicle can-

not be observed. The image displayed on the screen differs depending on the posi-

tion of the door mirror.

●

The field of view of the camera is limited. Do not rely solely upon the Multi-terrain

Monitor.

As with unequipped vehicles, drive carefully while directly confirming the safety of

your surroundings.

Take particular care to avoid parked cars and other obstacles.

●

Do not drive the vehicle while only looking at the monitor screen under any circum-

stances.

Driving while only viewing the monitor screen may cause a collision or lead to an

accident, as the image displayed on the monitor screen may differ from actual condi-

tions. Make sure to visually check the surrounding areas with and without the mirror

while driving.

●

Always check visually and with the mirrors to confirm your intended path is clear.

●

The camera uses a special lens. The distances between objects and pedestrians that

appear in the image displayed on the screen will differ from the actual distances.

●

These are just some of the functions of the Multi-terrain Monitor. The steering wheel

timing and amount the steering wheel should be turned differs depending on the road

condition and road surface. Use the Multi-terrain Monitor with full understanding of

the above conditions.

Always confirm that there is appropriate space before attempting to park the vehicle.

●

Do not use the Multi-terrain Monitor in the following cases:
• On icy or slick road surfaces, or in snow

• When using tire chains

• When the back door is not closed completely

• On roads that are not flat or straight, such as curves or slopes.

●

In low temperatures, the screen may darken or the image may become faint. The

image could distort when the vehicle is moving, or you may become unable to see the

image on the screen. Be sure to check direct visually all around the vehicle before

proceeding.

CAUTION

■

Conditions which may affect the Multi-terrain Monitor system

●

If the tires are changed, the position of the guide lines displayed on the screen may be

incorrect. When changing the tires, consult your Lexus dealer.

●

Depending on the circumstances of the vehicle (number of passengers, amount of

luggage, etc.), the position of the guide lines displayed on the screen may change. Be

sure to check visually behind and all around the vehicle before proceeding.

●

Depending on the overall length of the vehicle (if a frontal protection system is

installed or the bumper has been replaced, etc.), the position of the distance guide-

lines displayed on the front monitor may change. Be sure to check visually behind and

all around the vehicle before proceeding.

●

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.

NOTICE

■

When using the Multi-terrain Monitor

●

Even if an obstacle is no longer visible on the side monitor, do not turn the steering

wheel further in the direction the vehicle is turning until the vehicle has moved com-

pletely past the obstacle. If the steering wheel is turned to full lock, the vehicle will turn

in the smallest possible turning circle, and may collide with the obstacle.

●

It may be difficult to judge distance with the image from the front camera due to the

characteristics of the lens. Drive carefully while checking the actual distance to the

obstacles displayed on the screen. Also, give your full attention to sudden bumps in

the road.

NOTICE

■

When a solid object is close by
The screen’s guide lines are designed for level

surfaces (road surface etc.) or flat walls etc.

When driving near the obstacle, the obstacle

may be displayed as outside the projected

course line, and it may seem that there is no

danger of a collision, however any sections pro-

truding from the wall may project over the

course line and the vehicle may actually collide

with the obstacle.

In cases such as this were the projected course

line passes close to obstacles, always visually

check the surroundings for safety.

How to use the camera

●

The Multi-terrain Monitor system may not operate properly in the following cases.
• If the front or the rear of the vehicle or the outside rear view mirror has been hit,

the camera’s position and mounting angle may have changed.

• 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. Strongly 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 fluorescent lights, sodium light or mercury light

etc., the lights and the illuminated areas may appear to flicker.

• The camera can be damaged by flying rocks and other debris.

●

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 possible.

■

Parking and stopping tips

●

If you immediately stop the engine after off-road driving, or park the vehicle for a long

time, the vehicle height may gradually lower. When parking, make sure there is nothing

under the vehicle that may come in contact with the underbody. The vehicle will return

to the set height when the engine is started.

●

The vehicle height may change as the temperature changes when the engine is

stopped. The vehicle will return to the set height when the engine is started.

■

When lowering the vehicle
In order to prevent the vehicle height from rising as occupants leave the vehicle, lowering

control will occur for a short while after the engine has been stopped.

■

The rear height control air suspension failure warning

●

If a malfunction occurs in the rear height control air suspension, N mode is automati-

cally selected. However, the system may not switch to N mode depending on the loca-

tion of the malfunction.

●

The warning message is displayed on the multi-information display, and the rear height

control air suspension cannot be activated until the malfunction is corrected.
