Operation of each component
■Recalling the driving position using the memory recall function
●Different driving positions can be registered for each electronic key. Therefore, the
driving position that is recalled may be different depending on the key being carried.
●If a door other than the driver’s door is unlocked with the smart access system with
push-button start, the driving position cannot be recalled. In this case, press the driving
position button which has been set.
■Customization
The unlock door settings of the memory recall function can be customized.
(Customizable features: →P. 5 9 4 )
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passenger or
squeeze your body against the steering wheel.

GX 460 _O M_ OM6 0F 6 8U _(U )4-1. Before driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running. This
prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with th e location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in oper- ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using
your left foot may delay response in an emergency, resulting in an accident.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the engine. Turning the engine off while driving
will not cause loss of steering or braking control, but the power assist to these systems
will be lost. This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: → P. 5 1 1
●Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause the brakes to overheat and lose effective-
ness. (→P. 1 9 4 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or not before driving at such speeds.

Driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to engine over-
heating. Additionally, if the vehicle is park ed in a poorly ventilated area, exhaust gases
may collect and enter the vehicle, leadin g to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking. In this case, braking is still
possible, but the brake pedal should be depressed more firmly than usual. Also, the
braking distance will increase. Have your brakes fixed immediately.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems: If one of the systems fails,
the other will still operate. In this case, the brake pedal should be depressed more
firmly than usual and the br aking distance will increase.
Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage the driveline components or propel the vehi-
cle forward or backward, causing an accident.

GX 460 _O M_ OM6 0F 6 8U _(U )4-1. Before driving
■AVS (adaptive variable suspension system)
The suspension can be switched fo
r improvement in driveability. (→P. 3 4 1 )
■Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differential or wheel bearing), Lexus recommends that you do not
tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to the addi-
tional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately 600 miles
(1000 km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize.

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
