2-1. Driving procedures

When driving
GX460_U.S.A. (OM60J00U)
Starting off on a steep uphillMake sure that the parking brake is set and shift the shift lever to
D.
Gently depress the accelerator pedal.
Release the parking brake.
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 600 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.

●In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beam on or off
manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights orfog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are chang-
ing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads,
gravel tracks etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead of the vehicle, such as a sign or a mir- ror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or distress to other drivers or pedestrians nearby.

CAUTION
■To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON-OFF” button when not in use.

Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those covered with rain, ice and snow
●On steep downhills, or where there are sudden changes between sharp up and
down gradients
●At entrances to expressways
●When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (f og, snow, sandstorm, etc.)
●When a buzzer is heard often
●When towing a trailer or emergency towing
●In traffic conditions where the vehicle is repeatedly sped up and slowed down at
frequent intervals

2-4. Using other driving systems
GX460_U.S.A. (OM60J00U)
CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (→P. 257) will not be activated, and a fatal or serious accident
may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
●Excessive exhaust gas (black smoke) is coming from the vehicle ahead or other
vehicles around you, obscuring your front view
●The rear section of the vehicle ahead is extremely dirty
●The vehicle ahead has higher ground clearance

●When driving with snow tires, 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 towing a trailer.

preted as lane markers (such as guardrails, curbs, reflector posts, etc.).
●When there is snow in the wheel tracks of the road.
●When there are shadows on the road running parallel with lane markers, or if a
shadow is covering the lane markers.
●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
highway.
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane.
