CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●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.)
●Vehicles that cut in suddenly
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:
●Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.

CAUTION
■Handling the driver monitor sensor (vehicles with driver monitor sensor)
Observe the following to ensure the driver monitor sensor can function effectively.
Failure to do so may result in a malfunction or may prevent the system from cor-
rectly determining the direction the driver is facing, resulting in an unexpected acci-
dent.
●Do not disassemble, damage, lift or pull on the sensor.
●Do not touch the sensor while driving.
●Do not wet or spill water on the sensor.
●Do not drop anything on or allow anything to hit against the sensor. Do not sub-
ject the sensor to an impact.
●Make sure that there are no scratches, dirt or stickers on the side of the sensor
that faces the driver.
●Do not place any objects in front of the side of the sensor that faces the driver or
cover the sensor.
■Determining the direction the driver is facing (vehicles with driver monitor sen-
sor)
The direction the driver is facing may not be determined correctly if the following
conditions exist:
●There is an object between the driver mo nitor sensor and the driver’s face, such
as when the sensor is blocked.
●A part of the driver’s face is covered.
●The sensor or the driver’s face is exposed to intense light such as sunlight.
●The driving posture is improper.

Selecting a trailer ballUse the correct trailer ball for your application. Trailer ball load rating
Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer cou-
pler. Most couplers are stamped
with the required trailer ball size.
Shank length
Protrudes beyond the bottom of
the lock washer and nut at least 2
threads.
Shank diameter
Matches the ball mount hole diam-
eter size.
Connecting trailer lights
Use the wire harness stored in the
rear end under body.

■Before towing
Check that the following conditions are met:
●The vehicle’s tires are properly inflated. (P. 76 0 )
●Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion.
●All trailer lights work.
●All lights work each time you connect them.
●The trailer ball is set up at the proper height for the coupler on the trailer.
●The vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue load, overloading,
worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses.

CAUTION
■To avoid accident or injury
●Do not use cruise control when you are towing.
●Slow down and downshift before descending steep or long downhill grades. Do
not make sudden downshifts.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently.
This could cause the brakes to overheat and result in reduced braking efficiency.
■Hitches
●If you wish to install a trailer hitch, contact your Lexus dealer.
●Use only a hitch that conforms to the total trailer weight requirement.
●Follow the directions supplied by the hitch manufacturer.
●Lubricate the hitch ball with a light coat of grease.
●Remove the trailer hitch whenever you are not towing a trailer. After removing
the hitch, seal any mounting hole in the vehicle body to prevent entry of any sub-
stances into the vehicle.
■When towing a trailer
●If the total trailer weight exceeds 1000 lb . (453 kg), trailer brakes are required.
●Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s brak-
ing effectiveness.
●Never tow a trailer without using a safety chain securely attached to both the
trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is
a risk 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 use axle-mounted hitches, as they can cause damage to the axle housing,
wheel bearings, wheels or tires.
■Brakes
Lexus recommends trailers with brakes that conform to all applicable federal and
state/provincial regulations.
■Safety chain
A safety chain must always be used between the towing vehicle and the trailer.
Leave sufficient slack in the chain for turns. The chain should cross under the trailer
tongue to prevent the tongue from droppi ng to the ground in the case that it
becomes damaged or separated. For the correct safety chain installation proce-
dure, ask your Lexus dealer.
■Do not directly splice trailer lights
Directly splicing trailer lights may dama ge your vehicle’s electrical system and
cause a malfunction.

Trailer towing tipsYour vehicle will handle differently when towing a trailer. The 3 main
causes of vehicle-trailer accidents are driver error, excessive speed and
improper trailer loading. Keep the following in mind when towing:
● Before starting out, check the trai ler lights and the vehicle-trailer con-
nections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with the trailer attached in an
area away from traffic until you be come accustomed to the feel of the
vehicle.
● Reversing with a trailer attached is difficult and requires practice Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the left. Move yo ur hand to the right to move the
trailer to right. (This is generally opposite to reversing without a trailer
attached.) Avoid sharp or prolon ged turning. Have someone guide
you when reversing to reduce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
