3504-5. Using the driving support systems
LS460/LS460L_GE (OM50G06E)
■After the vehicle has been parked in the sun
The LKA system functions may not be available and a warning message ( P. 614)
will be displayed for a while after driving has started. In such cases, turn the LKA sys-
tem off and turn it on again after normal temperature returns. When the temperature
in the cabin decreases and the temperature around the camera sensor ( P. 344)
becomes suitable for its operation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure warning
will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lanes are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Raised pavement marker” or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the li ght level changes rapidly, such as the
entrance to or exit from a tunnel
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens
●When driving on roads that are branching or merging

CAUTION
■Situations unsuitable for LKA
Do not use LKA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains or similar equipment
●When the tires have been excessively worn, or when the tire inflation pressure is
low
●When there are objects or structures along the roadside that might be misinter-
preted as lane markers (such as guardrails, curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand, dirt,
etc.
●When there are visible lines on the pavement from road repairs, or if the remains
of old lane markers are still visible on the road
●When driving on slippery roads, such as those covered with rain, ice or snow
●When driving in a lane other than the driving or passing lanes on a freeway or
highway
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane
NOTICE
■To prevent damage to or incorrect operation of the LKA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension.
If any suspension parts need to be replaced, contact your Lexus dealer.
●Do not install or place anything on the hood or the grille. Also, do not install a
grille guard (bull bars, kangaroo bar etc.).
●Do not modify the sun visor.
If the sun visor needs to be replaced, contact your Lexus dealer.
●If the windshield needs to be replaced, contact your Lexus dealer.

CAUTION
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the
driving assist systems, and may cause a system to malfunction.

CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious
injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for
the snow tires being used.
●Use snow tires on all, not just some wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used,
or 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting opera-
tions that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
●Do not use LKA (Lane-Keeping Assist) system. (if equipped)
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow ti res from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.

◆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.
