158 4-1. Before driving
LS500_OM_(U)_1810 WARNING●
In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while the
engine is running, and apply the park-
ing brake as necessary.●
If the vehicle is stopped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.●
Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.■
When the vehicle is parked●
Do not leave glasses, cigarette lighters,
spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter
or spray can, and may lead to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plas-
tic material of glasses to deform or
crack.
• Soft drink cans may fracture, causing
the contents to spray over the interior
of the vehicle, and may also cause a
short circuit in the vehicle’s electrical
components.
●
Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be lit accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.
●
Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument pane l or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle. ●
Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire. ●
Always apply the parking brake, shift
the shift position to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended
while the engine is running.
If the vehicle is parked with the shift
position in P but the parking brake is
not set, the vehicle may start to move,
possibly leading to an accident. ●
Do not touch the exhaust pipes while
the engine is running or immediately
after turning the engine off.
Doing so may cause burns. ■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated 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 in creases 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 vehi-
cle.
●
Vehicles without Lexus Safety System

not operate, do not follow other vehi-
cles 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 brak-
ing distance will in crease. Have your
brakes fixed immediately.

■
If the vehicle becomes stuck
Do not spin the wheels excessively when
a driven wheel is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident. NOTICE■
When driving the vehicle ●

output. ●
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 set the parking brake, and shift
the shift position 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
damaging the wheels, underside of the
vehicle, etc.
●
Make sure to idle the engine immedi-
ately after high-load driving. Stop the
engine only after the turbocharger has
cooled down.
Failure to do so may cause damage to
the turbocharger.
■
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

Driving 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.162)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.446)
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 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 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.Calculation formula for your
vehicle

Things that must not be carried in the
trunk
The following things may cause a fire if
loaded in the trunk:
●
Receptacles containing gasoline

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. Vehicle load limits Vehicle load limits include total
load capacity, seating capacity,
towing capacity and cargo capac-
ity.
 Total load capacity (vehicle
capacity weight):  P.446
Total load capacity means the com-
bined weight of occupants, cargo
and luggage.
 Seating capacity:5 occupants
