■Hill-start assist control is operational when
●The system has detected that the vehicle is moving backward.
●The shift lever is in the D or S position.
●The brake pedal is not depressed.
■VGRS is disabled when
VGRS may stop operating in the following situations.
In this event, the steering wheel may move from its straight forward position, but it
will return when the system restarts.
●When the steering wheel is operated for an extended period of time while the vehi-
cle is stopped or is moving very slowly
●When the steering wheel has been held fully to the left or right
●When the 12-volt battery is low or the voltage temporarily drops
The center position of the steering wheel may change when VGRS is disabled. How-
ever, the position will return to normal after VGRS is reactivated.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC, hill-start assist
control and VGRS systems
●A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the hybrid system is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has occurred in
any of these systems.
●Any of the following conditions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
●The steering wheel may be moved slightly or a sound may be heard when the
hybrid system is started or stopped. None of these indicate that a malfunction has
occurred.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.
■Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the hybrid system off
and then on again will automatically reactivate the TRC/VSC systems.

CAUTION
■Before using the Lexus night view
Never depend on this system only.
Lexus night view is intended as a supplemental aid to help you see pedestrians and
road conditions ahead of the vehicle. As there are limits to the system, do not rely
solely on the system while in use, and drive safely while observing the following
precautions.
■When using the Lexus night view
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Never drive while looking at the Lexus night view screen only.
●Do not look continuously at the Lexus ni ght view screen while driving. Pedestri-
ans, objects etc. ahead of the vehicle may be overlooked by the system. The sys-
tem should always be used as a supplemental aid only.
●Lexus night view is designed to help you see objects better when driving in dark-
ness on a road with few curves. Do not use the Lexus night view in well-lit areas or
on roads with many curves or slopes. There may be areas that cannot be dis-
played by the system due to the road conditions (curve size, gradient, etc.)
●Lexus night view may be unable to project some features at an appropriate level
of brightness. Some or all parts of certain features may be dark or difficult to see.
Do not rely solely on the Lexus night view, and drive carefully while checking the
surroundings for safety, as you would with a normal vehicle. Also, the following
features and conditions may not be displayed clearly.
Features that are difficult to display:
• Clothing of a pedestrian made of a certain kind of material (ex. leather jackets)
• The characters on signs and billboards
• The information on road signs
Conditions in which display is difficult:
• Unfavorable weather conditions such as rain, fog, snowfall, snow storms etc.
• There are large puddles of water on the road surface following rainfall
• The area of the windshield in front of the camera is fogged up, dirty or icy
• The areas around the headlights are covered with ice, snow, mud etc.
• The 12-volt battery voltage is remarkably low
• There are bright lights ahead of the vehicle

3844-6. Driving tips
LS600h/LS600hL_EE(OM50G20E)
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
●Have a service technician inspect the condition of the 12-volt 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 specified size and brand, and that chains match the
size of the tires.
Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropriate
to the prevailing weather conditions.

■When the hybrid battery cooling system operates
●If the hybrid battery cooling system operates when the air conditioning is off, a
message will be shown on the multi-information display and the air conditioning will
automatically turn on. ( P. 121)
●The sound of the air flow may change when cool air flows from the rear roof vents
or the air purifier is in operation. This occurs when the hybrid battery is being
cooled and does not indicate a malfunction.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Pollen removal mode
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the pollen removal mode is turned off.
■Air purifier (with rear air conditioning system)
The air purifier will turn on when turning the rear air conditioning system on.
■When the outside temperature falls to nearly 0 C (32F)
The dehumidification function may not operate even when “A/C” is selected.

■Customization
Some functions can be customized. (Customizable features P. 634)
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
■nanoe 
Do not disassemble or repair the generator because it contains high voltage parts.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional if the generator needs repair.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the hybrid
system is off.
■To prevent damage to the nanoe 
Do not insert anything into the driver’s side vent, attach anything to it, or use sprays
around the driver’s side vent. These th ings may cause the generator not to work
properly.
