■Parking brake indicator light
●Depending on the engine switch mode, the parking brake indicator light will come
on and stay on as described below:
IGNITION ON mode: Comes on until the parking brake is released.
Not in IGNITION ON mode: Stays on for approximately 15 seconds.
●When the engine switch is turned off with the parking brake set, the parking brake
indicator light will stay on for about 15 seconds. This does not indicate a malfunc-
tion.
■Parking brake engaged warning buzzer
A buzzer will sound if the vehicle is driven at a speed of approximately 5 km/h (3
mph) or more with the parking brake engaged.
■When there is a malfunction in the system
Warning lights and/or warning message will turn on or flash. ( P. 607, 614)
Depending on the condition, the parking brake indicator light may flash.
■Usage in winter time
 P. 399
NOTICE
■When parking the vehicle
Before you leave the vehicle, set the parking brake, shift the shift lever to P and
make sure that the vehicle does not move.
■When the system malfunctions
Stop the vehicle in a safe place and check the warning messages.
■When the parking brake cannot be released due to a malfunction
Use the parking brake release tool to manually release the parking brake.
( P. 629)
Driving the vehicle with the parking brake set will lead to brake components over-
heating, which may affect braking performance and increase brake wear.

3024-3. Operating the lights and wipers
LS460/LS460L_GE (OM50G06E)
■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■Dripping prevention wiper sweep
After washing and the wiper has operated several times, the wipers operate one
more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 170 km/h
(106 mph).
■Effects of vehicle speed on wiper operation
Even when the wipers are not in “AUTO” mode, vehicle speed affects the time until
the drip prevention wiper sweep occurs.
With low speed windshield wiper operation selected, wiper operation will be
switched from low speed to intermittent wiper operation only when the vehicle is sta-
tionary.
(However, when the sensor sensitivity is adjusted to the highest level, the mode can-
not be switched.)
■Raindrop sensor
●If the wiper is turned to “AUTO” mode while the engine switch is in IGNITION ON
mode, the wipers will operate once to show that “AUTO” mode is activated.
●If the temperature of the raindrop sensor is 90 C (194F) or higher, or -15C
(5 F) or lower, automatic operation may not occur. In this case, operate the wip-
ers 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. 445
●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.

4044-6. Driving tips
LS460/LS460L_GE (OM50G06E)
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive fuel consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce the burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Turn the A/C switch on only when both heating and dehumidifying
are needed, and if only heating is needed, turn the A/C switch off. Turning the
A/C switch on when unnecessary leads to excessive fuel consumption.
◆Performing idling stops
●Avoid unnecessary idling. Stop the engine when parking the vehicle to
reduce excessive fuel consumption, even it is only for a short period of time.
●Except in severe environment, such as when the outside temperature is
extremely low, warming up the engine before driving is unnecessary.
Rather than idling, it is more efficien t to drive the vehicle gently to warm up
each part while avoiding increasing the engine revolutions unnecessarily
and accelerating or decelerating suddenly.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆Regular maintenance
●Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel economy. Also, as snow tires can
cause large amounts of friction, their us e on dry roads can lead to poor fuel
economy. Use tires that are appropri ate for the season and road condi-
tions.
●Use oil and fluid of the recommended quality, which affect fuel consump-
tion and the life of the vehicle. Also, check oil and fluid periodically.

5186-2. Maintenance
LS460/LS460L_GE (OM50G06E)
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechan-
ical ability and a few basic automotive tools. Simple instructions for how to per-
form them are presented in this section.
Note, however, that some maintenance tasks require special tools and skills.
These are best performed by qualified technicians. Even if you are an experi-
enced do-it-yourself mechanic, we recommend that repairs and maintenance be
conducted by your Lexus dealer who will keep a record of maintenance on your
vehicle. This record could be helpful should you ever require Warranty Service.
■Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that indi-
cate service is needed. Some important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air conditioning
system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide leak.
Drive with the windows open and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the
floor, vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal ( P. 125)
If you notice any of these clues, take your vehicle to your Lexus dealer as soon as
possible. Your vehicle may need adjustment or repair.
