■Screen description
The rear view monitor system screen will be displayed if the shift lever is
shifted to R while the engine switch is in IGNITION 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 display is

■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 distance/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. However, 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.

4387-3. Do-it-yourself maintenance
IS250_EE(OM53C51E)
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 “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 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 (vehicles with a tire pressure warning system)
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. 4 2 8 )
Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced. Other-
wise, the tire may separate from the wheel or cause a loss of handling control.
