156 4-1. Before driving
LS500_OM_(U)_1810 WARNING■
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 emergency, 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.
●
Vehicles without Lexus Safety System
+ A: 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 putt
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:
 P.406 ●
Vehicles with Lexus Safety System + A:
During normal driving, do not turn off
the engine. Turning the engine off
while driving will not cause loss of
steering or braking control, however,
power assist to the st eering will be lost.
This will make it more difficult to steer
smoothly, so you should pull over and
stop the vehicle as soon as it is safe to
do so.
In the event of an emergency, such as if
it becomes impossible to stop the vehi-
cle in the normal way:  P.406●
Use engine braking (downshift) to
maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may
cause the brakes to overheat and lose
effectiveness. (  P.167)●
Do not adjust the positions of the
steering wheel, the seat, or the inside
or outside rear view mirrors while driv-
ing.
Doing so may result in a loss of vehicle
control. ●
Always check that all passengers’
arms, heads or other parts of their
body are not outside the vehicle. ●
Do not drive in excess of the speed
limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140
km/h) unless your vehicle has
high-speed capability tires. Driving
over 85 mph (140 km /h) may result in
tire failure, loss of control and possible
injury. Be sure to consult a tire dealer
to determine whether the tires on your
vehicle are high-speed capability tires
or not before driving at such speeds.
■
When driving on slippery road sur-
faces
●
Sudden braking, acceleration and
steering may cause tire slippage and
reduce your ability to control the vehi-
cle.
●
Sudden acceleration, engine braking
due to shifting, or changes in engine
speed could cause the vehicle to skid.

1574-1. Before driving
LS500_OM_(U)_1810 4
Driving WARNING●
After driving through a puddle, lightly
depress the brake pedal to make sure
that the brakes are functioning prop-
erly. Wet brake pads may prevent the
brakes from functioning properly. If the
brakes on only one side are wet and
not functioning properly, steering con-
trol may be affected.■
When shifting the shift position●
Do not let the vehicle roll backward
while a forward driving position is
selected, or roll forward while the shift
position is in R.
Doing so may cause the engine to stall
or lead to poor brake and steering
performance, resulting in an accident
or damage to the vehicle.●
Do not shift the shift position to P while
the vehicle is moving.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Do not shift the shift position to R while
the vehicle is moving forward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●
Do not shift the shift position to a driv-
ing position while the vehicle is moving
backward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●
Changing the shift position to N while
the vehicle is moving will disengage
the engine from the transmission.
Engine braking is not available when N
is selected. ●
Be careful not to change the shift posi-
tion with the accelerator pedal
depressed. Changing the shift posi-
tion to any positions other than P or N
may lead to unexpected rapid acceler-
ation of the vehicle that may cause an
accident and result in death or serious
injury.
After changing the shift position, make
sure to confirm the current shift posi-
tion displayed on the shift position indi-
cator inside the meter. ■
Brake pad wear
If any of the following situations occurs,
have the brake pads visually checked and
replaced by your Lexus dealer as soon as
possible. ●
If the brake pad wear limit of a brake
pad is found to have been exceeded
when visually checking the brake pads
for each wheel (for the brake pad wear
limit, refer to P.451) ●
If a warning message is displayed on
the multi-information display (only the
right-side pads can be detected)
Rotor damage may result if the pads are
not replaced when needed.
F SPORT models: Moderate levels of the
brake pad and disc wear allow enhanced
braking power. As a result, the discs may
wear more quickly than conventional
brake discs. Therefore, when replacing
the brake pads, Lexus recommends that
you also have the thickness of the discs
measured.
It is dangerous to drive the vehicle when
the wear limits of the brake pads and/or
those of the brake discs are exceeded.
■
When the vehicle is stopped
●
Do not race the engine.
If the vehicle is in any gear other than P
or N, the vehicle may accelerate sud-
denly and unexpectedly, causing an
accident.

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
+ A: If the brake booster device does
not operate, do not follow other vehi-
cles closely and avoid hills or sharp
