■Panoramic view & rear view/wide rear view
The screen can be displayed when the shift lever is in R.
■Guide lines
If the back door is not closed, guide lines will not be displayed. If the guide lines do not
display even when the back door is closed, have the vehicle inspected at your Lexus
dealer.
WARNING
■Guide lines
The tire position indicator lines and vehicl e position indicator lines may differ from
actual vehicle positions depending on the number of passengers, cargo weight, road
grade, road surface conditions, brightness of the surrounding environment, etc. Always
drive the vehicle while confirming the safety of your surroundings.
■When using panoramic view & rear view or wide rear view
●If the vehicle width extension guide lines and projected course lines are not aligned
with the steering wheel in the center position, drive straight on a road without as little
traffic and as few bends or curves as poss ible for approximately 5 minutes or more. If
the symptom is not resolved, have the vehicle inspected by your Lexus dealer.
●Rear vehicle width extension guide lines are displayed wider than the actual vehicle
width. When backing up, always confirm th e safety of your surroundings and the area
to the rear of the vehicle.

●Using the vehicle width lines
The relative distance of obstacles from the vehicle width lines can be con-
firmed.• Approach the shoulder, but do not allow the vehicle width line to overlap the curb or other obstacles.
• After confirming the di stance to the shoulder, maneuvering the vehicle
so that the vehicle width line and the curb or other obstacle are parallel
allows the vehicle to be parked evenly.

Observe the following precautions. Failure to do so may result in an unexpected
accident. Also, when driving, make sure to directly confirm the safety of your sur-
roundings and the area to the rear of the vehicle.

WARNING
■Conditions under which the Multi-te rrain Monitor should not be used
Do not use the Multi-terrain Monitor in the following situations. The system may not
operate properly, resulting in an unexpected accident.
●When driving on an icy, snow-covered or otherwise slippery road surface
●When using tire chains or a spare tire
●When either front door or the back door is not completely closed
●When driving on an uneven road, such as a hill
●When tires or suspension parts other than those specified are equipped
When the tires are replaced, the position indicated by the guide lines displayed on the
screen may differ.

Driving
●When the ground behind the vehicle slopes down sharply
The distance guide lines are displayed further away than the actual dis-
tance. Therefore, obstacles on a downward slope appear closer than the
actually are. In the same way, the actua l course of the vehicle will differ from
the course indicated by the guide lines.
●When the vehicle is tilted
When the vehicle is tilted due to the number of passengers or weight of the
load, actual distances and vehicle course will differ.

■Differences between the panoramic view, rear view and wide rear view and
actual roads
●Distance guide lines
Guide lines are displayed in referenc e to the road surface and cannot be
used to determine the distance of three-dimensional objects from the vehi-
cle. Confirm the safety of your surr oundings directly. On the screen, it
appears that a truck is parking at po int according to the distance guide
lines. However, in reality if you back up to point , you will hit the truck.
On the screen, it appears that is closest and is farthest away. How-
ever, in reality, the distance to and is same, and is farther than
and .
●Under vehicle terrain view
The tire position indicator lines and ve hicle position indicator lines may dif-
fer from actual vehicle positions depending on the number of passengers,
weight of the load, road grade, road surface conditions, brightness of the
surrounding environment, etc. Always drive the vehicle while directly con-
firming the safety of your surroundings.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
●If the tire pressure drops below a predet ermined level, the driver is warned by
a screen display and a warning light. ( P. 520)
●The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P. 93)
The illustration used is intended as an
example, and may differ from the image
that is actually disp layed on the multi-
information display.
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pr essure warning valves and transmitters
must also be installed.
When new tire pressure wa rning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. ( P. 475)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following circum-
stances:
●When changing the tire size.
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing travel-
ing speed or load weight.
●After registering the ID codes. ( P. 475)
When the tire pressure warning system is initialized, the current tire inflation
pressure is set as the benchmark pressure.

■Tire inflation pressure check interval
You should check tire inflation pressure ever
y two weeks, or at least once a month. Do
not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, ha ve it checked by your Lexus dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at le ast 3 hours and has not been driven for more
than 1 mile or 1.5 km, you will get an accu rate cold tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appearance.
●It is normal for the tire inflat ion pressure to be higher after driving as heat is generated
in the tire. Do not reduce tire inflation pressure after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.

Wheels
When replacing wheels, care should be ta
ken to ensure that they are equivalent
to those removed in load capacity, diameter, rim width, and inset
*.
Replacement wheels are available at your Lexus dealer.
*: Conventionally referred to as “offset”.
Lexus does not recommend using the following:
●Wheels of different sizes or types
●Used wheels
●Bent wheels that have been straightened
●Use only Lexus wheel nuts and wrenches designed for use with your alumi-
num wheels.
●When rotating, repairing or changing your tires, check that the wheel nuts are
still tight after driving 1000 miles (1600 km).
●Be careful not to damage the aluminum wheels when using tire chains.
●Use only Lexus genuine balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels.
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters that allow the tire pressure warning system to provide advance warning in the event
of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning
valves and transmitters must be installed. (P. 473)
If a wheel is bent, cracked or heavil y corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
