Trailer ball
■Before towing
Check that the following conditions are
met:
●Ensure that your vehicle’s tires are prop-
erly inflated. ( P.413)
●Trailer tires are inflated according to the
trailer manufacturer’s recommendation.
●All trailer lights work as required by law.
●All lights work each time you connect
them.
●The trailer ball is set at the proper height
for the coupler on the trailer.
●The trailer is level when it is hitched.
Do not drive if the trailer is not level, and
check for improper tongue weight, over-
loading, worn suspension, or other possi-
ble 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
purposes.
■AVS (Adaptive Variable Suspension
System) (if equipped)
The suspension can be switched for
improvement in driveability. ( P.261)
■Break-in schedule
If your vehicle is new or equipped with any
new power train components (such as an
engine, transmission, differential or wheel
bearing), Lexus recommends that you do
not tow a trailer until the vehicle has been
driven for over 500 miles (800 km).
After the vehicle has been driven for over
500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km),
drive the vehicle at a speed of less than 50
mph (80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. (See “Warranty
and Services Guide”, “Owner’s Manual
Supplement” or “Scheduled Mainte-
nance”.)
●Retighten the fixing bolts of the towing
ball and bracket after approximately 600
miles (1000 km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds, passing
vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer,
causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer
straight ahead.
Do not try to control trailer swaying by
turning the steering wheel.
• Begin releasing th e accelerator pedal
immediately but very gradually to reduce
speed.
Do not increase speed. Do not apply
vehicle brakes.
If you make no extreme correction with the
steering or brakes, your vehicle and trailer
should stabilize.
●After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropri-
ate, if possible.

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 head
lights is detected.
●House lights, street lights, red traffic sig-
nals, 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 oncom-
ing and preceding vehicles
• When a oncoming or preceding vehicle only 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 th e 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, 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 beams on or off manually
rather than relying on the Automatic
High Beam system.
• In bad weather (rain, snow, fog, sand- storms, 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, tail 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 inter-
mittently changing brightness and dark-
ness. • 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 re flective 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.
NOTICE

●Do not subject the camera sensor to a
strong impact.
●Do not disassemble the camera sen-
sor.

The Blind Spot Monitor function uses
radar sensors to detect vehicles that
are traveling in an adjacent lane in the
area that is not reflected in the outside
rear view mirror (the blind spot), and
advises the driver of the vehicles exis-
tence via the BSM outside rear view
mirror indicator.
■The Blind Spot Monitor function
detection areas
The areas that vehicles can be
detected in are outlined below.
WARNING
■Handling the radar sensor
One Blind Spot Monitor sensor is
installed inside the left and right side of
the vehicle rear bumper respectively.
Observe the following to ensure the
Blind Spot Monitor system can function
correctly.
●Keep the sensor an d its surrounding
area on the bumper clean at all times.
●Do not subject the sensor or surround-
ing area on the bumper to a strong
impact. If the sensor moves even
slightly off position, the system may
malfunction and vehicles that enter the
detection area may not be detected. If
the sensor or surrounding area is sub-
ject to a strong impact, always have the
area inspected by your Lexus dealer.
●Do not disassemb le the sensor.
●Do not attach accessories or stickers
to the sensor or surrounding area on
the bumper.
●Do not modify the sensor or surround-
ing area on the bumper.
●Do not paint the rear bumper any
color other than an official Lexus color.
●If the radar sensor needs to be
replaced, contact your Lexus dealer.

consecutive curves, or uneven surfaces
• When vehicle lanes are wide, or when driving on the edge of a lane, and the
vehicle in an adjacent lane is far away
from your vehicle
• When towing a trailer (vehicles with tow-
ing package)
• When items such as a bicycle carrier are installed on the rear of the vehicle
• When there is a significant difference in height between your vehicle and the
vehicle that enters the detection area
• Immediately after the Blind Spot Monitor function is turned on
●Instances of the Blind Spot Monitor func-
tion unnecessarily detecting a vehicle
and/or object may increase in the follow-
ing situations:
• When the sensor is misaligned due to a strong impact to the sensor or its sur-
rounding area
• When the distance between your vehicle and a guardrail, wall, etc. that enters the
detection area is short
• When driving up an d down consecutive
steep inclines, such as hills, dips in the
road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehi-
cle traveling in a lane other than the adja- cent lanes enters the detection area
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short
• When a bicycle carrier or other acces- sory is installed to the rear of the vehicle
• When towing a trailer (vehicles with tow-
ing package)
The Rear Cross Traffic Alert function operates when your vehicle is in reverse. It
can detect other vehicles approaching from the right or left rear of the vehicle. It
uses radar sensors to alert the driver of the other vehicle’s existence through flash-
ing the BSM outside rear view mirror indicators and sounding a buzzer.

WARNING
■Cautions regarding the use of the sys-
tem
The driver is solely responsible for safe
driving. Always drive safely, taking care
to observe your surroundings.
The Blind Spot Monitor function is a sup-
plementary function which alerts the
driver that a vehicle is present in the blind
spot. Do not overly rely on the Blind Spot
Monitor function. The function cannot
judge if it is safe to change lanes, there-
fore over reliance could cause an acci-
dent resulting in death or serious injury.
According to conditions, the system may
not function correctly. Therefore the
driver’s own visual confirmation of safety
is necessary.
