Normal city driving or
high-speed driving (at the
highway speed limit or rec- ommended speed)
Not neces-sary
Steep hill driving or continu-
ous driving (race track driving etc.)Approxi-mately 1 minute
WARNING
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous injury.
■When starting the vehicle
Always keep your foot on the brake
pedal while stopped with the engine run-
ning. This prevents the vehicle from
creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with
the location of the brake and accelera-
tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera- tor pedal instead of the brake pedal
will result in sudden acceleration that
may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in
operating the pedals. Make sure to
operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle
only slightly. This allows you to depress
the brake and accelerator pedals
properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal
using your left foot may delay
response in an emer gency, resulting in
an accident.
●Do not drive the vehicle over or stop
the vehicle near flammable materials.
The exhaust system and exhaust gases
can be extremely hot. These hot parts
may cause a fire if there is any flamma-
ble material nearby.
●During normal driving, do not turn off
the engine. Turning the engine off
while driving will not cause loss of
steering or braking control, but the
power assist to these systems will be
lost. This will make it more difficult to
steer and brake, so you should pull
over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emer-
gency, such as if it becomes impossible
to stop the vehicle in the normal way:

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, transmis-
sion, transfer (AWD models), differen-
tials, etc.

*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 lug-
gage on your vehicle.
WARNING
■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 visi on, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●Stow cargo and luggage in the trunk
whenever possible.
●To prevent cargo and luggage from
sliding forward during braking, do not
stack anything in the enlarged trunk.
Keep cargo and luggage low, as close
to the floor as possible.
●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
enlarged trunk. It is not designed for
passengers. They should ride in their
seats with thei r seat belts properly fas-
tened.
●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 Center Display
●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.
