Driving
Cargo capacity depends on the total
weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) — (Total weight of occupants)
Steps for Determining Correct Load
Limit —
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or XXX
lbs.” on your vehicle’s placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX
kg or XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity.
For example, if the “XXX” amount
equals 1400 lbs. and there will be five
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 − 750
(5  150) = 650 lbs.)
(5) Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and lug-
NOTICE
■If you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat
tire (
P.424)
■When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
the following serious damage to the vehi-
cle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a flooded
road and the vehicle is flooded, be sure
to have your Lexus dealer check the fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, hybrid
transmission, rear differential, etc.
●Lubricant condition for bearings and
suspension joints (where possible),
and the function of all joints, bearings,
etc.
Cargo and luggage
Take notice of the following infor-
mation about storage precautions,
cargo capacity and load.

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.458)
●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.
■Adaptive Variable Suspension System
(if equipped)
The suspension can be switched for
improvement in driveability. ( P.279)
■Break-in schedule
If your vehicle is new or equipped with any
new power train components (such as an
engine, hybrid transmission, rear differential
or wheel bearing), Le xus 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. (if enabled, Trailer Sway
Control can also help to stabilize the vehicle
