CAUTION
■Trunk easy closer
■Power trunk lid
Observe the following precautions when operating the power trunk lid.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●If the trunk closer switch is pressed while the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may suddenly shut after it opens automatically. Make
sure the trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk lid may detect an abnormality and
automatic operation may be stopped. In this case, the trunk lid has to be operated
manually. Take extra care in this situation, as the stopped trunk lid may suddenly
shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the power
switch is turned to ON mode or the hybrid system is started during automatic
operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk lid may not operate, causing itself to malfunction, or the trunk lid may
suddenly shut closed again after it is opened.
In the event that the trunk lid is left slightly
open, the trunk easy closer will automatically
close it to the fully closed position. It takes
several seconds before the trunk easy closer
begins to operate. Be careful not to catch fin-
gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
injuries.

2364-1. Before driving
LS600h/LS600hL_EE(OM50G20E)
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes periodically or whenever the parking brake
shoes and/or drum are replaced. Have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional perform the bedding down opera-
tion.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. ( P. 622)
■For efficient use
●Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be generated.
The hybrid battery (traction battery) will discharge, requiring unnecessary engine
power to recharge.
●Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decelera-
tion will make more effective use of the electric motor (traction motor) without hav-
ing to use gasoline engine power.
●Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power, resulting
in poor acceleration. Battery power can be restored by driving with the accelerator
pedal slightly released.
●Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may dis-
charge the hybrid battery (traction battery). The vehicle cannot run if the hybrid
battery (traction battery) is discharged.
