Move the height adjuster up and down as
needed until yo u hear a click.
The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi- cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■Replacing the belt after the preten-
sioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.

WARNING
■Adjustable shoulder anchor
Always make sure th e shoulder belt is
positioned across the center of your
shoulder. The belt should be kept away
from your neck, but not falling off your
shoulder. Failure to do so could reduce
the amount of protection in an accident
and cause death or serious injuries in the
event of a sudden stop, sudden swerve or
accident.

WARNING
■Seat belt pretensioners
Observe the following precautions to
reduce the risk of in jury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
●Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result , the seat belt pre-
tensioner for the front passenger’s seat
may not activate in the event of a colli-
sion.
●If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

WARNING
■When adjusting the seat position
●Take care when ad justing the seat
position to ensure that other passen-
gers are not injured by the moving
seat.
●Do not put your hands under the seat
or near the moving parts to avoid
injury.
Fingers or hands may become
jammed in the seat mechanism.
■Seat adjustment
To reduce the risk of sliding under the lap
belt during a collision, do not recline the
seat more than necessary.
If the seat is too rec lined, the lap belt may
slide past the hips and apply restraint
forces directly to the abdomen, or your
neck may contact the shoulder belt,
increasing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made while
driving as the seat may unexpectedly
move and cause the driver to lose control
of the vehicle.

Contact your Lexus dealer for further
information about additional require-
ments such as a towing kit, etc.
■Matching trailer ball height to trailer
coupler height
No matter which class of tow hitch applies,
for a more safe trailer hookup, the trailer
ball setup must be the proper height for the
coupler on the trailer. Coupler
Trailer ball
■Before towing
Check that the following conditions are
met:
●Ensure that your vehicle’s tires are prop-
erly inflated. ( P.408)
●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.
■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
Trailer towing (vehicles with
towing package)
Your vehicle is de signed primarily
as a passenger-and-load-carrying
vehicle. Towing a trailer can have an
adverse impact on handling, per-
formance, braking, durability, and
fuel consumption. For your safety
and the safety of others, you must
not overload your vehicle or trailer.
You must also ensure that you are
using appropriate towing equip-
ment, that the towing equipment
has been installed correctly and
used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking
performance are affected by trailer
stability, brake performance and
setting, trailer brakes, the hitch and
hitch systems (if equipped).
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with your trailer’s character-
istics and operating conditions.
Lexus warranties do not apply to
damage or malfunction caused by
towing a trailer for commercial pur-
poses.

• There is a rut or hole in the surface of the
road
• When the vehicle is driven on a metal
cover (grating), such as those used for
drainage ditches
• The vehicle is driven on a steep slope

flooded road
●Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system returns to
normal)

types), fog lights, a fender pole or a wire-
less antenna) are inst alled near the sen-
sors

nose tilts up or down)
• The direction of the sensor has deviated
due to a collision or other impact
■Situations in which the system may not
operate normally

●Ice, snow, dirt, etc., may have adhered to
the sensor. If this occurs, remove the ice,
snow, dirt, etc., from the sensor to return
the system to normal.
Also, a warning message may be dis-
played at low temperatures due to ice
forming on the sensor, and the sensor
may not detect obstac les. Once the ice
melts, the system will return to normal.
●If this message is shown even after
removing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehicle inspected by your
Lexus dealer.
●System initialization may not have been
performed after remova l and installation
of the 12-volt battery. Perform system ini-
tialization.

operate properly, and may result in an
unexpected accident.
●Do not perform work such as modifi-
cation, disassembly or painting
●Only perform replacements using
genuine parts
●Do not subject the area around the
sensors to any impacts
●Do not damage the sensors, and
always keep them clean
■Handling the suspension
Do not modify the suspension, as
changes to the height or incline of the
vehicle may prevent the sensors from
correctly detecting obstacles, may cause
the system not operate, or may cause the
system to operate unnecessarily.
NOTICE
■Preventing unnecessary operation
In the following situations, turn the Park-
ing Support Brake func tion (for static
objects) OFF. The system may operate
even though there is no possibility of a
collision.

Vehicles with 225/60R18 tires
Tire chains cannot be mounted on the
225/60R18 tires.
Snow tires should be used instead.
Regulations regarding the use of tire
chains vary depending on location and
type of road. Always check local regu-
lations before installing chains.
■Tire chain installation
Observe the following precautions when
installing and removing chains:
●Install and remove tire chains in a safe
location.
●Install tire chains on the front tires only.
Do not install tire chains on the rear tires.
●Install tire chains on fr ont tires as tightly as
possible. Retighten chains after driving 1/
4 - 1/2 mile (0.5 - 1.0 km).
●Install tire chains following the instruc-
tions provided with the tire chains.
 Specific design characteristics give
it a higher center of gravity than
ordinary passenger cars. This vehi-
cle design feature causes this type
of vehicle to be more likely to roll-
over. Utility vehicles have a signifi-
cantly higher rollover rate than
other types of vehicles.
 It is not designed for cornering at
the same speeds as ordinary pas-
senger cars any more than low-
slung sports cars designed to per-
form satisfactorily under off-road
conditions. Therefore, sharp turns at
excessive speeds may cause roll-
over.

■Utility vehicle precautions
Always observe the following precau-

the driver and all passengers should
always fasten their seat belts.
