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.406)
■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, transaxle,
transfer (AWD models), rear differen-
tial (AWD models), etc.
●Lubricant condition for the propeller
shaft (AWD models), 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.

gage load capacity calculated in Step
4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
( P.158)
Vehicles without towing package: Lexus
does not recommend towing a trailer with
your vehicle. Your vehicle is not designed
for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( P.430)
When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage load capacity will be C lb. (kg) as
follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb. (kg)
*1: A =Weight of people
*2: B =Total load capacity
*3:C =Available carg o and luggage load
In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb. (kg)
*4: D =Additional weight of people
*5: E =Available cargo and luggage load
As shown in the example above, if the
number of occupant s increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.

WARNING
■Things that must not be carried in the
luggage compartment
The following things may cause a fire if
loaded in the luggage compartment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals
from being depressed properly, may
block the driver’s visi on, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●Stow cargo and luggage in the lug-
gage compartment whenever possi-
ble.

WARNING
●Do not stack cargo and luggage in the
luggage compartment higher than the
seatbacks.
●When you fold down the rear seats,
long items should not be placed
directly behind the front seats.
●Never allow anyone to ride in the lug-
gage compartment. It is not designed
for passengers. They should ride in
their seats with their seat belts prop-
erly fastened.
●Do not place cargo or luggage in or on
the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
•On the luggage cover
• On the instrument panel
•On the dashboard
●Secure all items in the occupant com-
partment.
■Capacity and distribution
●Do not exceed the maximum axle
weight rating or the total vehicle
weight rating.
●Even if the total load of occupant’s
weight and the cargo load is less than
the total load capacity, do not apply the
load unevenly. Improper loading may
cause deterioration of steering or
braking control which may cause
death or serious injury.
■Roof luggage carrier precautions
Observe the following precautions:
●Place the cargo so that its weight is dis-
tributed evenly between the front and
rear axles.
●If loading long or wide cargo, never
exceed the vehicle overall length or
width. (
P.430)
●Before driving, make sure the cargo is
securely fastened on the roof luggage
carrier.
●Loading cargo on the roof luggage
carrier will make the center of gravity
of the vehicle higher. Avoid high
speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers,
otherwise it may resu lt in loss of con-
trol or vehicle rollover due to failure to
operate this vehicle correctly and
result in death or serious injury.
●If driving for a long distance, on rough
roads, or at high speeds, stop the vehi-
cle now and then during the trip to
make sure the cargo remains in its
place.
●Do not exceed 165 lb. (75 kg) cargo
weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with a
moon roof or panoramic moon roof)
Be careful not to scratch the surface of
the moon roof or panoramic moon roof.

Driving
Control can also help to stabilize the vehicle
and trailer.)
●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.
• Check the load in the vehicle. Make sure the vehicle is not overloaded
after occupants get in.
If you cannot find any problems, the speed
at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer
combination. Drive at a lower speed to pre-
vent instability. Remember that swaying of
the towing vehicle-trailer increases as
speed increases.
WARNING
■Trailer towing precautions
To tow a trailer safely, use extreme care
and drive the vehicle in accordance with
the trailer’s characteristics and operating
conditions. Failure to do so could cause
an accident resulting in death or serious
injury. Vehicle stability and braking per-
formance are affected by trailer stability,
brake setting and performance, and the
hitch. Your vehicle will handle differently
when towing a trailer.
■To avoid accident or injury
●Do not exceed the TWR, unbraked
TWR, GCWR, GVWR or GAWR.
●If the gross trailer weight is over 2000
lb. (907 kg), a sway control device with
sufficient capacity is required.
●Adjust the tongue weight within the
appropriate range. Place heavier loads
as close to the trailer axle as possible.
●Do not exceed 65 mph (104 km/h),
the posted towing speed limit or the
speed limit for your trailer as set forth
in your trailer owner’s manual, which-
ever is lowest. Slow down sufficiently
before making a turn, in cross winds,
on wet or slippery surface, etc. to help
avoid an accident. If you experience a
vehicle-trailer inst ability from reduc-
ing a certain speed, slow down and
make sure you keep your vehicle
speed under the speed of which you
experience the instability.
●Do not make jerky, abrupt or sharp
turns.
●Do not apply the brakes suddenly as
you may skid, resulting in jackknifing
and loss of vehicle control. This is
especially true on wet or slippery sur-
faces.
●Do not exceed the trailer hitch assem-
bly weight, gross vehicle weight, gross
axle weight and tra iler tongue weight
capacities.
●Do not use the following systems when
trailer towing.
• Dynamic radar cruise control with full-speed range
• LTA (Lane Tracing Assist)
• PCS (Pre-Collision System)
• BSM (Blind Spot Monitor) (if equipped)
●Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts while descending steep or long
downhill grades.

■TRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating. Drive the vehicle
carefully in conditions where stability and
power may be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner-
ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on
slippery road surfaces.
●When Active Cornering Assist fre-
quently operates, Active Cornering
Assist may temporarily stop operating
to ensure proper operation of the
brakes, TRAC and VSC.
■Hill-start assist control does not oper-
ate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the TRAC/VSC/Trailer Sway
Control is activated
The slip indicator light flashes. Always
drive carefully. Re ckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRAC/VSC/Trailer Sway
Control systems are turned off
●Be especially careful and drive at a
speed appropriate to the road condi-
tions. As these are the systems to help

force, do not turn the
TRAC/VSC/Trailer Sway Control sys-
tems off unless necessary.
●Trailer Sway Control is part of the VSC
system and will not operate if VSC is
turned off or expe riences a malfunc-
tion.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflat ion pressure level.
The ABS, TRAC, Trailer Sway Control
and VSC systems will not function cor-
rectly if different tires are installed on the
vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspensi on will affect the
driving assist systems, and may cause a
system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not
able to reduce trailer sway in all situa-
tions. Depending on many factors such
as the conditions of the vehicle, trailer,
road surface and driving environment,
the Trailer Sway Control system may not
be effective. Refer to your trailer owner’s
manual for information on how to tow
your trailer properly.

Maintenance and care
roads, we recommend using snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also have
radial construction. Do not install studded
tires without first checking local regula-
tions for possible restrictions. Snow tires
should be installed on all wheels. ( P.271)
■If the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same in terval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low ti re inflation pressure
before serious problems arise.

WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drive trai n as well as danger-
ous handling characteristics, which may
lead to an accident resulting in death or
serious injury.
●Do not mix tires of different makes,
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those
recommended by Lexus.
●Do not mix differently constructed
tires (radial, bias-b elted or bias-ply
tires).
●Do not mix summer, all season and
snow tires.
●Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
●Do not tow if your vehicle has a com-
pact spare tire installed.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle’s wheels and body.
■If tire inflation pressure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
