The buzzer sounds and a message is shown on the multi-information display in the
instrument cluster when the power switch is turned off and the driver’s door is
opened with the moon roof open.
■Customization
Settings (e.g. linked door lock operation) can be changed.
(Customizable features P. 634)
CAUTION
Observe the following precautions.
Failure to do so may cause death or serious injury.
■Opening the moon roof
●Do not allow any passengers to put their hands or heads outside the vehicle while
it is moving.
●Do not sit on top of the moon roof.
■Closing the moon roof
●The driver is responsible for moon roof opening and closing operations.
In order to prevent accidental operation, especially by a child, do not let a child
operate the moon roof. It is possible for children and other passengers to have
body parts caught in the moon roof.
●Check to make sure that all passengers do not have any part of their body in a
position where it could be caught when the moon roof is being operated.
●When using the smart entry & start system, wireless remote control or mechani-
cal key and operating the moon roof, operate the moon roof after checking to
make sure that there is no possibility of any passenger having any of their body
parts caught in the moon roof. Also, do not let a child operate moon roof by the
smart entry & start system, wireless remote control or mechanical key. It is possi-
ble for children and other passengers to get caught in the moon roof.
●When exiting the vehicle, turn the power switch off, carry the key and exit the vehicle
along with the child. There may be accidental operation, due to mischief, etc., that may possibly lead to an accident.
■Jam protection function
●Never use any part of your body to intentionally activate the jam protection func-

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.

■Downshifting restrictions warning buzzer
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or paddle shift switch (if equipped) is operated. (A buzzer will
sound twice.)
■When driving with cruise control, dynamic radar cruise control or dynamic radar
cruise control with full speed range activated
Even when performing the following actions with the intent of enabling engine brak-
ing, engine braking will not activate because cruise control, dynamic radar cruise
control or dynamic radar cruise control with full speed range will not be canceled.
●While driving in D or S mode, downshifting to 7, 6, 5 or 4. ( P. 289, 293, 307)
●When switching the driving mode to sport mode while driving in D position.
( P. 334)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if th e power switch is turned off after driving
in snow mode.
■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in
starting.
The shift lever can be shifted from P only when the power switch is in ON mode and
the brake pedal is being depressed.
■If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a
problem with the shift lock system. Have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional imme-
diately.
The following steps may be used as an emergency measure to ensure that the shift
lever can be shifted.
Releasing the shift lock:
Turn the power switch to ON mode ( P. 248) and check that the parking brake is
set.
Turn the power switch off.
Depress the brake pedal.
