When towing a trailer
Lexus recommends trailers with brakes that conform to any applicable federal and
state/provincial regulations. ●
If the gross trailer weight exceeds unbraked TWR, trailer brakes are required. Lexus
recommends trailers with brakes that conform to all applicable federal and state/pro-
vincial regulations. ●
Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s braking
effectiveness. ●
Never tow a trailer without using a safety ch ain securely attached to both the trailer
and the vehicle. If damage occurs to the coupling unit or hitch ball, there is danger of
the trailer wandering into another lane.
NOTICE ■
When installing a trailer hitch
Use only the position recommended by your Lexus dealer. Do not install the trailer
hitch on the bumper; this may cause body damage. ■
Do not directly splice trailer lights
Do not directly splice trailer lights. Dire ctly splicing trailer lights may damage your
vehicle’s electrical system and cause a malfunction.

The Automatic High Beam can be operated when
The power switch is in ON mode. ■
Camera sensor dete ction information●
High beam may not be automatically tu rned off in the following situations:
• When oncoming vehicles sudd enly appear from a curve
• When the vehicle is cut in front of by another
• When oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees ●
High beam may be turned off if an oncoming vehicle that is using fog lights without
using the headlights is detected. ●
House lights, street lights, red traffic sign als, and illuminated billboards or signs may
cause the high beam to turn off. ●
The following factors may affect the amount of time taken to turn high beam on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and preceding
vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle on ly has operational lights on one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface, etc.)
• The number of passengers and amount of luggage ●
High beam may be turned on or off when unexpected by the driver.●
In the situations below, you should consider turning the high beams on or off manually
rather than relying on the Automatic High Beam system.
• The system is not able to correctly dete ct the surrounding brightness levels, and
flashes or exposes nearby pe destrians to the high beam.
• 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 camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, ta il lights or fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty, are
changing color, or are not aimed properly.
• When driving through an area of intermit tently 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 repeat edly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed, etc.
• The driver believes that the high beam may be causing problems or distress to other
drivers or pedestrians nearby.

Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident result-
ing in death or serious injury. ●
Roads where there are pede strians, cyclers, etc.●
In heavy traffic ●
On roads with sharp bends ●
On winding roads ●
On slippery roads, such as thos e covered with rain, ice or snow●
On sharp inclines or declines
Vehicle speed may exceed the set speed when driving down a steep hill. ●
Roads with continuous inclines and declines ●
At entrances to freeways and highways ●
When weather conditions are bad enough that they may prevent the sensors from
detecting correctly (fog, snow, sandstorm, heavy rain, etc.)●
When an approach warning buzzer is heard often ●
When your vehicle is towing a trailer or during emergency towing ■
When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insuff icient or operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning (  P. 245) will not be activated, which may lead to an accident resulting in
death or serious injury. ●
Vehicles that cut in suddenly ●
Vehicles traveling at low speeds ●
Vehicles that are not moving in the same lane ●
Vehicles with small rear ends (traile rs with no load on board, etc.)
●
Motorcycles traveling in the same lane ●
When water or snow thrown up by the surrounding vehicles hinders the detecting of
the sensor

Cruise control can be set when ●
The shift lever is in D or range 4 or higher of S has been selected.●
Vehicle speed is above approximately 25 mph (40 km/h). ■
Accelerating after setting the vehicle speed ●
The vehicle can be accelerated by operating accelerator pedal. After accelerating, the
set speed resumes. ●
Even without canceling the cruise control, the set speed can be increased by first accel-
erating the vehicle to the desired speed and then pushing the lever down to set the new
speed. ■
Automatic cancelation of cruise control
Cruise control is automatically canceled in any of the fo llowing situations.●
Actual vehicle speed falls more than approximately 10 mph (16 km/h) below the set
speed. ●
Actual vehicle speed is below approximately 25 mph (40km/h). ●
VSC is activated. ●
TRAC is activated for a period of time. ●
When the VSC or TRAC system is turned off by pressing the VSC OFF switch. ■
If “Cruise Control Malfunction Visit Your De aler” is displayed on the multi-information
display
Press the “ON/OFF” button once to deactivate the system, and then press the button
again to reactivate the system.

• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 7 mph (10 km/h).■
Conditions that may trigger the system even if there is no possibility of a collision
If the following obstructs the front of the sens or, the system judges that a collision may be
possible and operates. ●
When passing by a vehicle while making left or right turns or passing a vehicle in an
opposite lane. ●
When the vehicle rapidly approaches an object in front of it (such as another vehicle,
toll gate, etc.) ●
When climbing a steep hill, etc., and there are structures in the upper region of the road
(billboards, low ceilings , street lamps, etc.)●
When driving through narrow passages or places with low ceilings (bridges, tunnels,
overhead passes, etc.) ●
When driving on an uneven road surface ●
When metal objects are on the road surface causing level differences or protrusions in
the road ●
When an extreme change in vehicle height occurs ●
When the radar sensor moves off position du e to its surrounding area being subjected
to a strong impact. ●
When there is an obstacle on the side of an entrance of a curb for road (guardrails, etc.) ●
When your vehicle is tilted upwards (due to towing a trailer or during emergency tow-
ing, heavy loads in the lu ggage compartment, etc.).
When the system is activated in the situations described above, ther e is also a possibility
that the brakes will be applied wi th a force greater than normal.■
Obstacles not detected
The sensor cannot detect plasti c obstacles such as traffic co nes. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
