CAUTION
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire due to
hybrid system overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to death or a
serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
●If the electronically controlled brake system does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase. Have your brakes
fixed immediately.
●The brake system consists of 2 or more individual hydraulic systems; if one of the
systems fails, the other(s) will still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase. Have
your brakes fixed immediately.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving,
as this may restrain driving torque.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at
the same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to move or
the vehicle may accelerate suddenly if the accelerator pedal is accidentally
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.

NOTICE
■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 vehicle:
●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 following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacit y) — (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 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
luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be trans- ferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
(→P. 1 9 0 )
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is not
designed for trailer towing.
Take notice of the following information about storage precautions,
cargo capacity and load:

Cargo capacity
Total load capacity (vehicle
capacity weight) (→P. 8 0 8 )
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 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 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 occupants 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 luggage on your vehicle.

CAUTION
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk:
●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 vision, or may result in items hitting the driver or passengers, possibly
causing an accident.
●Stow cargo and luggage in the trunk whenever possible.
●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 package tray
• On the instrument panel
• On the dashboard
• In front of the Remote Touch screen
●Secure all items in the occupant compartment.
■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 dete-
rioration of steering or braking control which may cause death or serious injury.
