Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start, wire-
less remote control and engine immobilizer system from operating properly.
(Ways of coping: P. 8 6 7 )●
When the electronic key battery is depleted ●
Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise●
When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices ●
When the electronic key is in contact wi th, or is covered by the following metal-
lic object
• Card to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs ●
When multiple electronic keys are in the vicinity ●
When other wireless keys (that emit radio waves) are being used nearby●
When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems ●
If window tint with a metallic content or metallic objects are attached to the rear

The meters and displa y illuminate when
The “ENGINE START STOP” switch is in IGNITION ON mode. ■
The brightness of the instrument panel lights
When the tail lights are turned on, the me ter’s brightness will be reduced slightly
unless the meter brightness level adjustment is set to the brightest setting.
If the tail lights are turned on when the surroundings are dark, the meter’s bright-
ness will be reduced slightly. However, wh en the surroundings are bright, such as
during the daytime, the meter’s brightness will not be reduced even if the tail lights
are turned on.
NOTICE■
To prevent damage to the engine and its components ●
Do not let the indicator needle of the ta chometer enter the red zone, which indi-
cates the maximum engine speed. ●
The engine may be overheating if the engine coolant temperature gauge is in the
red zone (“H”). In this case, immediatel y stop the vehicle in a safe place, and
check the engine after it has cooled completely. ( P. 8 7 3 )■
Vo l t m e t e r
When the voltmeter indicates 19 V or higher or 9 V or lower while the engine is
running, there may be a battery or chargi ng 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 immediately and check the amount of engine oil.
( P. 74 9 )
When the oil pressure drops even though the 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.

When driving
LX570_OM_OM60L21U_(U) NOTICE■
To prevent the water damage
Take all necessary safety measures to en sure that water dama ge to the engine or
other components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age. ●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the river bed for firmness. Drive slowly and
avoid deep water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.
