Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts
the driver using rapid beeping, indications on the multi-information dis-
play, and a sensory warning* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direction of the
center of the lane.
Lane keeping assist function
• This function will be active when the vehicle-to-vehicle distance con-
trol mode of the dynamic radar crui se control with full-speed range
( P. 328) is set with vehicle speed above approximately 72 km/h
(45 mph) and while the lane departure warning function is active.
• When the lane keeping assist function is active, a slight steering
torque will be applied, to help th e driver maintain the vehicle inside
the lane.
The lane keeping assist function will be temporarily canceled if the steering
wheel is not operated, or if you continue driving with your hands lightly touch-
ing the steering wheel. ( P. 349)

CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in handling
the ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or other
body parts while changing a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading
to bolt or disc wheel damage. In addition, the oil or grease can cause the
wheel nuts to loosen and the wheel may fall off, causing a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 140 N•m (14.3 kgf•m,
103 ft•lbf) as soon as possible after changing wheels.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel
while the vehicle is moving.
• When installing a tire, only use wheel nuts that have been specifically designed
for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle inspected by your Lexus dealer.

When trouble arises
LS460/LS460L_GE (OM50G06E)
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel con-
tact surface, the wheel nuts may
loosen while the vehicle is in motion,
causing the tire to come off.
Install the spare tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.
Turn the wheel nuts until the washers
come into contact with the disc wheel.
Lower the vehicle.
Firmly tighten each wheel nut two
or three times in the order shown
in the illustration.
Tightening torque:
