For safety and security
CAUTION
Hybrid battery (traction battery)
Your vehicle contains a sealed nickel-metal hydride battery. Never resell,
hand over or modify the hybrid battery. To prevent accidents, hybrid bat-
teries that have been removed from a disposed vehicle are collected
through any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, result-
ing in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and some-
one may touch a high voltage part, resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an acci-
dent is extremely high because the person receiving the vehicle may not
be aware of these dangers.
If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional. If the hybrid battery is not disposed of properly, it may cause
electric shock that can result in death or serious injury.

NOTICE
Hybrid battery air vents
Do not put foreign objects near the air vents. The hybrid battery (traction
battery) may overheat and be damaged.
Clean the air vents regularly to prevent the hybrid battery (traction bat-
tery) from overheating.
Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the bat-
tery may be damaged. Have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.

The meters and display illuminate when
The power switch is in ON mode.
Instrument panel brightness adjustment
The instrument panel brightness levels when the tail lights are on and off can
be adjusted individually. However, when the surroundings are bright (day-
time, etc.), turning on the tail lights will not change the instrument panel
brightness.
Limitation of brightness adjustment
The brightness of the instrument panel lights is automatically adjusted based
on the light sensor detecting how bright the surroundings are. However, if the
instrument panel brightness has been manually set to either the brightest or
darkest setting, the automatic adjustment will not be performed.
Hybrid System Indicator
Hybrid System Indicator is displayed when the driving mode is other than
the sport mode.
By keeping the indicator needle within Eco area, more Eco-friendly driving
can be achieved.
Charge area indicates regeneration* status. Regenerated energy will be
used to charge the battery.
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy. Charge area
Shows regenerative charging.
Hybrid Eco area
Shows that gasoline engine power is
not being used very often.
The gasoline engine will automatically
stop and restart under various condi-
tions.

CAUTION
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information dis-
play monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
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 including harmful carbon mon-
oxide (CO) may collect and enter the vehicle. This may lead to death or a
serious health hazard.
NOTICE
During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid system is oper-
ating while setting up the display features.

Head-up display
The head-up display may seem dark and hard to see when viewed through
sunglasses, especially polarized sunglasses.
Adjust the brightness of the head-up display or remove your sunglasses.
When the head-up display is turned off, it will remain off even if the power
switch is turned to ON mode after the power switch has been turned off.
The startup image will be displayed on the head-up display after the power
switch has been turned to ON mode while the head-up display switch is set

When the 12-volt battery is disconnected
The customize settings of the head-up display will be reset.
CAUTION
Before using the head-up display
Check that the position and brightness of the head-up display image does
not interfere with safe driving. Incorrect adjustment of the image’s position
or brightness may obstruct the driver’s view and lead to an accident, result-
ing in death or serious injury.
NOTICE
To prevent damage to components
Do not place any drinks near the head-
up display projector. If the projector
gets wet, electrical malfunctions may
result.
Do not place anything on or put stickers
onto the head-up display projector.
Doing so could interrupt head-up dis-
play indications.
