LS600h/LS600hL_EE(OM50G20E)
CAUTION
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious
injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening
it. Failure to do so may cause the trunk lid to suddenly shut again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to suddenly shut again
after it is opened.
●The trunk lid may suddenly shut if it is not
opened fully. It is more difficult to open or
close the trunk lid on an incline than on a
level surface, so beware of the trunk lid
unexpectedly opening or closing by itself.
Make sure that the trunk lid is fully open
and secure before using the trunk.
●When closing the trunk lid, take extra care
to prevent your fingers etc. from being
caught.
●When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the trunk
lid, it may result in hands or arms being
caught.

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.

2404-1. Before driving
LS600h/LS600hL_EE(OM50G20E)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■If a brake pad wear warning message is displayed
Have the brake pads checked and replaced by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional, as soon as possible.
Rotor damage can result if the pads are not replaced when needed.
Moderate levels of the brake pad and disc wear allow enhanced braking power. As
a result, the discs may wear more quickly than conventional brake discs. Therefore,
when replacing the brake pads, Lexus recommends that you also have the thick-
ness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on, and apply the
parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.

2424-1. Before driving
LS600h/LS600hL_EE(OM50G20E)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire due to
hybrid system overheating. Additionally, if the vehicle is parked in a poorly venti-
lated 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 electronically controlled brake system does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require 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.
●The brake system consists of 2 or more individual hydraulic systems; if one of the
systems fails, the other(s) will still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase. Have
your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may damage the driveline components or propel
the vehicle forward or backward, causing an accident.

CAUTION
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
●Receptacles containing gasoline

■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly, may block
the driver’s vision, or may result in items hitting the driver or passengers, possibly
causing an accident.
●Stow cargo and luggage in the trunk whenever possible.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver

Driving
LS600h/LS600hL_EE(OM50G20E)
AFS (Adaptive Front-lighting System) secures excellent visibility at inter-
sections and on curves by automatically adjusting the direction of the light
axis of the headlights according to vehicle speed and the degree of the
tire’s angle as controlled by steering input.
AFS operates at speeds of 10 km/h (6 mph) or higher.
■Daytime running light system
To make your vehicle more visible to othe r drivers during daytime driving, the day-
time running lights turn on automatically whenever the hybrid system is started and
the parking brake is released with the headlight switch off or in the position. (Illu-
minate brighter than the front position lights.)
Daytime running lights are not designed for use at night.
■Headlight control sensor
■Automatic light off system
●When the light switch is in or : The headlights turn off automatically if the
power switch is turned to ACCESSORY mode or turned off.
●When the light switch is in : The headlights and all lights turn off automatically if
the power switch is turned to ACCESSORY mode or turned off.
To turn the lights on again, turn the po wer switch to ON mode, or turn the light
switch off once and then back to or .
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on.
AFS (Adaptive Front-lighting System)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
