2044-1. Before driving
LS600hL_U(OM50E41U)
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 your Lexus dealer check and replace the brake pads as soon as possible.
The 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 “R EADY” 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 whil e the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible material is
nearby.

◆Total load capacity (vehicle capacity weight): (P. 5 3 8 )
Total load capacity me ans the combined weight of occupants, cargo
and luggage.
◆Seating capacity:
5-seat models
5 occupants (Front 2, Rear 3)
4-seat models
4 occupants (Front 2, Rear 2)
Seating capacity means the maximum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
◆Towing capacity
Lexus does not recommend towing a trailer with your vehicle.

LS600hL_U(OM50E41U)
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the
following situations. When EV drive mode is canceled, a buzzer will sound and the
EV drive mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” display is low.
( P. 113)
●Vehicle speed becomes more than about 25 mph (40 km/h).
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distan ce ranges from a few hundred meters to
approximately 0.6 mile (1 km). Driving is possible at speeds of less than approxi-
mately 25 mph (40 km/h). However, depend ing on vehicle conditions, there are sit-
uations when EV drive mode cannot be used. (The distance that is possible depends
on the hybrid battery [traction ba ttery] level and driving conditions.)
■Fuel economy
Your Lexus is designed to achieve the best possible fuel economy during normal
driving (using the gasoline engine and electric motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy.
CAUTION
■Caution while driving
When driving in EV drive mode no engi ne noise is made. As such, pedestrians,
people riding bicycl es or other people and vehicles in the surrounding area may
not be aware of the vehicle starting off or approaching them. Therefore, take extra
care while driving even if the vehicle proximity notification system is active.

heating, which may affect braking performance and increase brake wear.

2364-3. Operating the lights and wipers
LS600hL_U(OM50E41U)
■Daytime running light system
●To make your vehicle more visible to other drivers, the parking lights turn on auto-
matically (at an increased intensity) whenever the hybrid system is started and the
parking brake is released. Daytime running lights are not designed for use at night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel econ-
omy.
■Headlight control sensor
■Automatic light off system
●When the headlights are on: The headlights and tail lights turn off 30 seconds after
a door is opened and closed if the power switch is turned to ACCESSORY mode
or turned off. (The lights turn off immediat ely if on the key is pressed after all the
doors are closed.)
●When only the tail lights are on: The tail lights turn off automatically if the power
switch is turned to ACCESSORY mode or turned off and the driver’s door is
opened.
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to or .
If any of the doors or trunk lid is kept op en, the lights automatically turn off after 20
minutes.
■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.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading conditio n of the vehicle to ensure that the headlights do not
interfere with other road users. The sensor may not func tion 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.

2464-3. Operating the lights and wipers
LS600hL_U(OM50E41U)
■Raindrop sensor
●If the wiper is turned to “AUTO” mode while the power switch is in ON mode, the
wipers will operate once to show that “AUTO” mode is activated.
●If the temperature of the raindrop sensor is 194°F (90°C) or higher, or 5°F (-15°C)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than “AUTO” mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Outside rear view mirror defogger activation linked to windshield wiper operation
The outside rear view mirror defoggers automatically turn on when you operate the
windshield wipers.
The outside rear view mirror defoggers automatically turn off approximately 15 min-
utes after the wipers stop.
For details about the outside rear view mirror defoggers: P. 3 5 8
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpect edly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers or
anything else do not become ca ught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm.
The fluid may freeze on the windshield and cause low visibility. This may lead to an
accident, resulting in death or serious injury.
