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.

If the low speed four-wheel drive indicator light or the center differential lock
indicator light blinks ●
If the low speed four-wheel drive indicator light continues to blink when using
the four-wheel drive control switch, stop the vehicle completely, move the shift
lever to “N” and operate the switch again. ●
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 dis-
engages both the front and rear driveshafts from the powertrain and allows the
vehicle to move regardless of the shift po sition. (At this time, the indicator 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 injured. You must complete the shifting of
the transfer mode.
To complete the shifting, stop the vehicle completely, return the shift lever to “N”,
and confirm that the shift was completed (the indicator turns on/off). ●
If the engine coolant temperature is too low, the four-wheel drive control system
may not be able to shift. When the engine is warmer operate the switch again.
If the low speed four-wheel drive indicator light or the center differential lock indi-
cator light continues to blink even after attempting the above, there may be a mal-
function in the engine, the brake system or the four-wheel drive system. In this case,
you may not be able to shif t between “H4” and “L4”, and the center differential lock
may not be operable. Have the vehicle inspected by your Lexus dealer immediately.

LX570_OM_OM60L21U_(U) Winter driving tips Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the ve hicle in a manner appropriate to the
prevailing weather conditions.
■ Pre-winter preparations
● Use fluids that are appropria te to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspec t the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires. Ensure that all tires are the same size and brand, and that chains match
the size of the tires.

3922-5. Driving information
LX570_OM_OM60L21U_(U) ● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the tr ailer wheels will be closer than the
vehicle wheels to the inside of the turn. Co mpensate by making a
wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed ca n destabilize the trailer.
● Take care when passing other vehi cles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in “D”.
If in the S mode, the transmission shift range position must be in 5 or
lower.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do not
make sudden downshifts while descending steep or long downhill
grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your 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 eng ine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. (  P. 873)

Maintenance and care
LX570_OM_OM60L21U_(U) CAUTIONThe engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury
observe the following precautions. ■
When working on the engine compartment ●
Keep hands, clothing and tools away from the moving fans and engine drive belt. ●
Be careful not to touch the engine, radiator , exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot. ●
Do not leave anything that may burn easi ly, such as paper or rags, in the engine
compartment. ●
Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable. ●
Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.■
When working near the electric cooling fan or radiator grille
Be sure the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fan may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (  P. 7 5 4 )■
When working on or under the vehicle ●
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports. ●
Use eye protection to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE■
If you remove the air cleaner filter
Driving with the air cleaner removed may cause excessive engine wear due to dirt
in the air.
