Before driving CAUTION■
People suffering illness
Obtain medical advice and wear the seat belt in the proper way.■
When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to choking or other serious injuries that could
result in death.
If this occurs and the buckle cannot be un fastened, scissors shou ld be used to cut
the belt.■
Seat belt pretensioners ●
Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, wh ich prevents the sensor from detecting
the passenger's weight properly. As a resu lt, the seat belt pretensioner for the
front passenger's seat may not activate in the event of a collision.●
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.■
Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoul-
der. The belt should be kept away from yo ur 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.

Cargo and luggage
Capacity and distribution
Cargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of th e 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 av ailable 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 ve hicle, 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 no t safely exceed the available cargo
and luggage load capacity calculated in Step 4. Take notice of the following information about storage precautions, cargo
capacity and load.
● Stow cargo and luggage in the luggage compartment whenever
possible.
● Be sure all items are secured in place.
● Be careful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● For better fuel economy, do not carry unnecessary weight.

When driving (6)If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consul t this manual to determine how this
reduces the available cargo and luggage load capacity of your vehi-
cle.
(  P. 7 9 8 )
Calculation formula for your vehicle
Cargo capacity
Total load capacity (vehicle
capacity weight) (  P. 7 9 8 )
When 2 people with the combined weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity (vehicle ca pacity weight) of B lb.
(kg), the available amount of cargo an d luggage 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 cargo 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 lo ad will be reduced E lb. (kg) as fol-
lows:
C lb. (kg) - D* 4
lb. (kg) = E* 5
lb. (kg)
* 4
: D =Additional weight of people
* 5
: E =Available cargo and luggage load

2982-5. Driving information
As shown in the example above, if the number of occupants increases,
the cargo and luggage load will be re duced by an amount that equals the
increased weight due to the addition al occupants. In other words, if an
increase in the number of occupants ca uses an excess of the total load
capacity (combined weight of occupants plus cargo and luggage load),
you must reduce the cargo and luggage on your vehicle. CAUTION■
Things that must not be carri ed 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 result in death or serious injury. ●
Stow cargo and luggage in the lugga ge compartment whenever possible.●
Do not stack cargo and luggage in the luggage compartment higher than the
seatbacks.
Such items may be thrown about and possib ly injure people in the vehicle in the
event of sudden braking or in an accident.●
Do not place cargo or luggage in or on the following locations as the items may
get under the brake or accelerator pedal and prevent the pedals from being
depressed properly, block the driver’s vision, or hit the driver or passengers,
causing an accident:
• 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 compartment, as they may shift and injure some-
one in the event of sudden braking, sudden swerving or an accident.

When driving CAUTION●
Never allow anyone to ride in the luggage compartment. It is not designed for
passengers. They should ride in their seat s with their seat belt s properly fastened.
Otherwise, they are much more likely to suffer death or serious bodily injury, in
the event of sudden braking, sudden swerving or an accident.■
Capacity and distribution ●
Do not exceed the maximum axle weight ra ting 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 dete-
rioration of steering or braking control which may cause death or serious injury.■
Roof luggage carrier precautions (if equipped)
To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or
more genuine Lexus cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
●
Before driving, make sure the cargo is securely fastened on the roof luggage car-
rier.●
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 the result may be a loss of control or vehicle roll-
over due to failure to operate this vehicl e correctly and result in death or serious
injury.
●
If driving for long distances, on rough ro ads, or at high spee ds, stop the vehicle
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.
●
To reduce wind noise when there is no luggage loaded on the roof luggage car-
rier, move the front cross rail to the front-most position and the rear cross rail to
the rearmost position. ●
Place the cargo so that its weight is distrib-
uted evenly between the front and rear
axles. ●
If loading long or wide cargo, never exceed
the vehicle’s overall length or width.
