LX570_OM_OM60Q78U_(U) 2. Instrument cluster■
The meters and display illuminate when
The engine switch is in IGNITION ON mode. ■
The brightness of the instrument panel lights
When the tail lights are turned on, the meter’s brightness will be re duced slightly unless
the meter brightness leve l adjustment is set to the brightest setting.
If the tail lights are turned on when the surr oundings are dark, the meter’s brightness will
be reduced slightly. However, when the surro undings are bright, such as during the day-
time, the meter’s brightness w ill not be reduced even if th e tail lights are turned on.■
Customization
The meter display can be customized on the multi-information display. ( → P. 580)
WARNING ■
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, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury.
NOTICE ■
To prevent damage to the engine and its components●
Do not let the indicator needle of the tachometer enter the red zone, which indicates
the maximum engine speed. ●
The engine may be overheating if the engine coolant temperature gauge is in the red
zone (H). In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. ( → P. 552)■
Voltmeter
When the voltmeter indicates 19 V or higher or 9 V or lower while the engine is run-
ning, there may be a battery or charging system malfunction. Have the vehicle
inspected at your Lexus dealer. ■
Engine oil pressure gauge
When the value of the engine oil pressure gauge drops while the engine is running,
stop the vehicle in a safe place immediat ely and check the amount of engine oil.
( → P. 475)
When the oil pressure drops even though th e engine oil amount has not decreased, or
if the oil pressure does not increase when engine oil is added, contact your Lexus
dealer, as there may be a problem with the lubrication system.

How to use the cameras ●
Observe the following precauti ons. Failure to do so may prevent the Multi-terrain
Monitor from operating properly.
• Do not strike the camera area, or allow any objects to bump into it
If the camera or surrounding area has re ceived a strong impact, the camera posi-
tion, installation angle, etc., may deviate. If the camera is accidentally subjected to
an impact, have the vehicle inspected at your Lexus dealer.
• Do not remove, disassemble or modify the camera or surrounding parts
Doing so may result in the camera malfunct ioning. This also may result in a loss of
waterproof performance.
• If the camera lens is dirty, follow the above procedures to clean it
If the camera lens is damaged it cannot transmit a clear image.
Do not allow organic solvent, car wax, oil film remover, glass coating, etc. to con-
tact the camera cover
Doing so will negatively affect the camera co ver (resin). If this happens, wipe it off
immediately.
• When the outside temperature is cold, do not cause any sudden changes in tem-
perature, such as by applying hot water ●

When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: → P. 532
If none of the tires are punctured:
Turn the engine switch off then turn it to IGNITION ON mode. Check if the tire pressure
warning light comes on or flashes. 
If the tire pressure warning light comes on
After the temperature of the tires has lowere d sufficiently, check the inflation pressure
of each tire and adjust th em to the specified level.
If the warning light does not turn off even after several minutes have elapsed, check
that the inflation pressure of each tire is at the specified level an d perform initialization.
( → P. 487)
If the warning light does not turn off even after several minutes have elapsed, have the
vehicle inspected by your Lexus dealer immediately. 
If the tire pressure wa rning light flashes for 1 minute then stay on
There may be a malfunction in the tire pressure warnin g system. Have the vehicle
inspected by your Lexus dealer immediately. ■
The tire pressure warning light ma y turn on due to natural causes
The tire pressure warning light may turn on du e to natural causes such as natural air leaks
or tire inflation pressure changes caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light (after a few minutes).■
When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and transmitter. The
tire pressure warning light will tu rn on if the tire inflation pressu re of the spare tire is low. If
a tire goes flat, even though the flat tire is replaced with the spare tire, the tire pressure
warning light does not turn off. Replace the spare tire with the repaired tire and adjust the
proper tire inflation pressure. The tire pressu re warning light will tu rn off after a few min-
utes. ■
Conditions that the tire pressure wa rning system may not function properly
