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.

LX570_OM_OM60Q78U_(U) 4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When the vehicle is parked ●
If the shift lever is moved before the low speed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the po wertrain and allows the vehicle to move
regardless of the shift positi on. (At this time, the indi cator blinks and the buzzer
sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P.
You or someone else could be seriously injure d. You must complete the shifting of the
transfer mode. ( → P. 303)●
Do not touch the exhaust pipes while the engine is running or immediately after turn-
ing the engine off.
Doing so may cause burns. ■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to engine over-
heating. Additionally, if the ve hicle is parked in a poorly ventilated area, exhaust gases
may collect and enter the vehicle, leading to death or a serious health hazard. ■
When braking ●
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle. ●
If the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that re quire braking. In this case, braking is still
possible, but the brake pedal should be depressed more firmly than usual. Also, the
braking distance will increase. Have your brakes fixed immediately. ●
Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes. ●
The brake system consists of 2 individual hy draulic systems: If one of the systems fails,
the other will still operate. In this case, the brake pedal should be depressed more
firmly than usual and the bra king distance will increase.
Have your brakes fixed immediately. ■
If the vehicle becomes stuck
Do not spin the wheels excessive ly when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage the driveline components or propel the vehi-
cle forward or backward, causing an accident.

198
LX570_OM_OM60Q78U_(U) 4-1. Before driving●
Avoid jerky starts or sudden acceleration. ●
Avoid jerky steering and sharp turns, an d slow down before making a turn.●
Note that when making a turn, the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. Compensate by making a wider than normal
turning radius. ●
Slow down before making a turn, in cr osswinds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer. ●
Take care when passing other vehicles . Passing requires considerable dis-
tance. After passing a vehicle, do not fo rget the length of your trailer, and be
sure you have plenty of room before changing lanes. ●
To maintain engine braking efficien cy and charging system performance
when using engine braking, do not put the transmission in D.
If in the S mode, the transmission shift range position must be in 6 or lower.
( → P. 210)●
Instability happens more fr equently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending st eep or long downhill grades.●
Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency. ●
Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85°F [30°C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. ( → P. 552)

LX570_OM_OM60Q78U_(U) 4-2. Driving procedures■
When the steering lock cannot be released
■
Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, the motor may be suspended if the
engine is turned on and off re peatedly in a short period of time. In this case, refrain from
running the engine. After about 10 seconds, the steering lock motor will resume func-
tioning. ■
When “Smart Access System Malfunction See Owner’s Manual” is displayed on the
multi-information display
The system may be malfunctioning. Have th e vehicle inspected by your Lexus dealer,
immediately. ■
If the electronic key battery is depleted
→ P. 503 ■
If the smart access system with push-button start has been deactivated in a customized
setting
→ P. 546A message will be displayed on the multi-infor-
mation display.
Check that the shift lever is set in P. Press the
engine switch while turn ing the steering wheel
left and right.
WARNING ■
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu lting in death or serious injury.■
Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, re sulting in death or serious injury.■
Stopping the engine in an emergency ●
If you want to stop the engine in an em ergency while driving th e vehicle, press and
hold the engine switch for more than 2 seco nds, or press it briefly 3 times or more in
succession. ( → P. 511)
However, do not touch the engine switch wh ile driving except in an emergency. Turn-
ing the engine off while drivin g will not cause loss of steering or braking control, but
the power assist to these systems will be lost . This will make it more difficult to steer
and brake, so you should pull over and stop the vehicle as soon as it is safe to do so. ●
If the engine switch is operated while the vehicle is running, a warning message will be
shown on the multi-information display and a buzzer sounds. ●
When restarting the engine after it was turn ed off while driving, shift the shift lever to
N and press the engine switch.
