Screen description
The rear view monitor system screen will be displayed if the shift lever
is shifted to R while the power switch is in ON mode.
Vehicle width guide lines
The line indicates a guide path when the vehicle is being backed straight
up.
The displayed width is wider than the actual vehicle width.
Vehicle center guide lines
These lines indicate the estimated vehicle center on the ground.
Distance guide line
The line shows points approximately 0.5 m (1.5 ft.) (red) from the center of
the edge of the bumper.
Distance guide line
The line shows distance behind the vehicle, a point approximately 1 m (3
ft.) (blue) from the edge of the bumper.
Lexus parking assist-sensor display (if equipped)
If an obstacle is detected while the Lexus parking assist-sensor is on, a dis-
play is shown at the top right corner of the screen.

Differences between the screen and the actual road
The distance guide lines and the vehicle width guide lines may not
actually be parallel with the dividing lines of the parking space, even
when they appear to be so. Be sure to check visually.
The distances between the vehicle width guide lines and the left and
right dividing lines of the parking space may not be equal, even when
they appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road surfaces. In
any of the following situations, there is a margin of error between the
fixed guide lines on the screen and the actual distance/course on the
road.
When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the vehicle
than the actual distance. Because
of this, objects will appear to be
farther away than they actually
are. In the same way, there will
be a margin of error between the
guidelines and the actual dis-
tance/course on the road.
When the ground behind the vehicle slopes down sharply
The distance guide lines will
appear to be further from the
vehicle than the actual distance.
Because of this, objects will
appear to be closer than they
actually are. In the same way,
there will be a margin of error
between the guidelines and the
actual distance/course on the
road.

Vehicle width guide lines
Visually check the surroundings and the area behind the vehicle. In the
case shown below, the truck appears to be outside of the vehicle width
guide lines and the vehicle does not look as if it hits the truck. How-
ever, the rear body of the truck may actually cross over the vehicle
width guide lines. In reality if you back up as guided by the vehicle
width guide lines, the vehicle may hit the truck.

4687-3. Do-it-yourself maintenance
IS300h_EE(OM53B95E)
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
*: Conventionally referred to as “off-
set”.
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
aluminum wheels.
When rotating, repairing or changing your tires, check that the wheel
nuts are still tight after driving 1600 km (1000 miles).
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
transmitters that allow the tire pressure warning system to provide advance warn-
ing in the event of a loss in tire inflation pressure. Whenever wheels are replaced,
tire pressure warning valves and transmitters must be installed. (P. 451)
Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of han-
dling control.
