Displays the estimated maximum distance that can be driven with the quantity
of fuel remaining and the distance driv en after the hybrid system was started
respectively. • This distance is computed based on your average fuel consumption. As a result,
the actual distance that can be driven may differ from that displayed.
• When only a small amount of fuel is added to the tank, the display may not be
updated.
When refueling, turn the power switch off. If the vehicle is refueled without turning
the power switch off, the display may not be updated.■

Suspension of the settings display
In the following situations, th e settings display using the meter control switches will be
suspended. ●
When a warning message appears on the multi-information display●
When the vehicle begins to move ■
Tire inflation pressure ●
It may take a few minutes to display the tire inflation pressure after the power switch is
turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted. ●
“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions. ●
Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.■

Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area such as a
garage, exhaust gases includin g harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to death or a serious health hazard.
NOTICE ■
The multi-information disp lay at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed. ■
During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid syst em is operating while
setting up the display features.

Before using the LDA
Do not over rely on the LDA. The LDA does not drive the vehicle automatically, nor
does it reduce the amount of care you need to take. As such, the driver must always
assume full responsibility for understandin g his/her surroundings, for operating the
steering wheel to correct the driving line, and for driving safely. Also, take occasional
rests from fatigue due to driving over long periods of time, etc.
Inappropriate or negligent driving co uld lead to an unexpected accident.■
Do not drive without holding the steering wheel
While the steering control function is operating, when the system judges that the vehi-
cle is being driven without holding the steering wheel, a warning message is displayed.
(  P. 2 7 1 )
Inappropriate steering wheel operations and/or negligent driving could lead to an
unexpected accident. When driving, firmly ho ld the steering wheel and keep safe driv-
ing in mind. ■
To avoid operating the LDA by mistake
Switch the LDA off using the LDA switch when not in use. (  P. 2 7 2 )■
Situations unsuitable for LDA
Do not use the LDA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident. ●
When driving with snow tires, tire ch ains, a spare tire, or similar equipment●
When a tire with a different structure, maker, brand, or tread pattern is used. ●
When remain tread of the tire or the air pressure is insufficient●
When restructuring the suspension ●
When there are objects or structures along the roadside that might be misinterpreted
as lane markers (such as guardrails, a curb, reflector posts, etc.) ●
When driving on snowy roads ●
When pavement lane markers are difficult to see due to rain, snow, fog, sand, dust,
etc. ●
When there are visible lines on the pavement from road repairs, or if the remains of
old lane markers are still visible on the road ●
When driving on a road with lane closures due to maintenance, or when driving in a
temporary lane ●
When driving on road surfaces that are slippery from rain, snow, etc.●
When driving in traffic lanes other than highways and freeway ●

If you notice any symptoms
If you notice any of the following symp toms, refer to the likely cause and the
solution, and re-check.
If the symptom is not resolved by the solution, have the vehicle inspected by
your Lexus dealer.Things you should know Likely cause Solution
 The image is difficult to see
• The vehicle is in a dark area
• The temperature around the lens is
either high or low
• The outside temperature is low
• There are water droplets on the cam-
era
• It is raining or humid
• Foreign matter (mud, etc.) is adhering
to the camera
• There are scratches on the camera
• Sunlight or headlights are shining
directly into the camera
• The vehicle is under fluorescent lights,
sodium lights, mercury lights etc. If this happens due to these causes, it
does not indicate a malfunction.
Back up while visually checking the vehi-
cle’s surroundings. (Use the monitor
again once conditions have been
improved.)
The image on the Lexus parking assist
monitor system screen can be adjusted.
(  P. 3 5 2 )
 The image is blurry
Dirt or foreign matter (such as water
droplets, snow, mud, etc.) is adhering to
the camera. Flush the camera with a large quantity of
water. After that, rinse the camera lens
with water and wipe it clean with a soft
and wet cloth.
 The image is out of alignment
The camera or surrounding area has
received a strong impact. Have the vehicle inspected by your Lexus
dealer.
 The guide lines are very far out of alignment
The camera position is out of alignment. Have the vehicle inspected by your Lexus
dealer.
• The vehicle is tilted (there is a heavy
load on the vehicle, tire pressure is low
due to a tire puncture, etc.)
• The vehicle is used on an incline. If this happens due to these causes, it
does not indicate a malfunction.
Back up while visually checking the vehi-
cle’s surroundings.
