GX 460 _O M_ OM6 0F 6 8U _(U )4-5. Using the driving support systems
CAUTION
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the vehicle auto-
matically, nor does it reduce the amount of care you need to take. As such, the driver
must always assume full responsibility fo
r understanding his/her surroundings, for
operating the steering wheel to correct th e driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using the “LDA” switch when not in use.
■Situations unsuitable for LDA system
Do not use LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains, a spare tire, or similar equipment
●When driving with non-standard parts or aftermarket equipment installed (including
modified tires and suspensions, etc.).
●When there are objects or structures along the roadside that might be misinterpreted
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 in a lane other than the driving or passing lanes on a freeway or high-
way.
●When driving on a road with lane closures due to maintenance, or when driving in a
temporary lane

Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally
apply water to the vehicle body, wheel
wells and underside of the vehicl e to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Automatic car washes
●Fold the mirrors back before washing the vehicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows
and the air suspension unit.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use hard brushes or
abrasive cleaners. Do not use strong or harsh chemical cleaners. Use the same mild
detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving for
long distance in the hot weather.
●Wash detergent from the wheels immediately after use.

CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components etc. to catch fire.
■When cleaning the windshield (vehicles with rain-sensing windshield wiper)

●If something bumps against the windshield
●If you directly touch the raindrop sensor bo dy or if something bumps into the raindrop

When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.
■Precautions regarding the Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunction.
If this occurs, consult your Lexus dealer.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wipers may
operate unexpectedly in the following situa-
tions, and may result in hands being caught or
other serious injuries and cause damage to the
