In the following situations the system may not be able to correctly detect the surround-
ing brightness level. This may cause the lo w beams to remain on or the high beams to
flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (heavy ra in, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equal to that of he adlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing color,
or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of intermittently changi ng brightness and darkness
• When frequently and repeated ly driving ascendin g/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel roads, etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object ahea d of the vehicle, such as a sign or mirror
• When the back of a preceding vehicle is highly reflective, such as a container on a
truck
• When the vehicle's headlights are damaged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams repeat-
edly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling pedestri-
ans or other drivers■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in high beam position.
• Automatic High Beam switch is on.
Turn the engine switch to IGNITION ON mode.
Within 30 seconds after , repeat pulling th e headlight switch lever to the original
position then pushing it to the high beam position quickly 10 times, then leave the lever
in high beam position.
If the sensitivity is changed, the Automatic High Beam indicator is turn on and off 3
times.
Automatic High Beam (headlights) may turn on even when the vehicle is stopped. 1

Enabling/disabling the pre-collision system
The pre-collision system can be enabled/disabled on ( P. 97) of the
multi-information display. The system is automatically enabled each time the engine switch is turned to IGNI-
TION ON mode.
If the system is disabled, the PCS
warning light will turn on and a mes-
sage will be displayed on the multi-
information display. ■
Changing the pre-collision warning timing
The pre-collision warning timing can be changed on ( P. 97) of the
multi-information display. The operation timing setting is retained when the engi ne switch is turned off.
Far The warning will begin to operate
earlier than with the default timing.
Middle This is the default setting.
Near The warning will begin to operate
later than with the default timing.Changing settings of the pre-collision system

Driving
RX350/RX350L_U This mode employs a radar sensor to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, de termines the current vehicle-to-vehicle
following distance, and operates to main tain a suitable following distance from
the vehicle ahead. Note that vehicle-to-vehicle distance will cl ose in when traveling on downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating the vehicle-to-vehicle distance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving sl ower than the set speed appearsWhen a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). Th e system will respond to
changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle
distance set by the driver. Approach warning warns you when the system cannot
decelerate sufficie ntly to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped by
system control). After the vehicle ahead starts off, pushing the cruise control lever up
or depressing the accelerator pedal will resume follow-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.Driving in vehicle-to-vehicle distance control mode
