160 4-1. Before driving
LS500h_OM_OM50F42U_(U) WARNING
• 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.●
The driver should pay extra attention
to pedestrians when the vehicle is
powered only by the electric motor
(traction motor). As there is no engine
noise, the pedestrians may misjudge
the vehicle’s movement. Even with the
vehicle proximity notification system
activate, drive with care as pedestrians
in the vicinity may still not notice the
vehicle if the surrounding area is noisy.●
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 hybrid system. Turning the hybrid
system off while driving will not cause
loss of steering or braking control,
however, power assist to the steering
will be lost. This will make it more diffi-
cult 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.420
●
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.174) ●
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.
●
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 forw ard while the shift
position is in R.
Doing so may result in an accident or
damage to the vehicle.

162 4-1. Before driving
LS500h_OM_OM50F42U_(U) WARNING■
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 hybrid
system and lock the vehicle.
Do not leave the vehicle unattended
while the “READY” indicator is illumi-
nated.
●
Do not touch the exhaust pipes while
the “READY” indicator is illuminated
or immediately after turning the hybrid
system off.
Doing so may cause burns. ■
When taking a nap in the vehicle
Always turn the hybrid system off. Other-
wise, if you accident ally move the shift
lever or depress the accelerator pedal,
this could cause an accident or fire due
to hybrid system overheating. Addition-
ally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may col-
lect 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. ●
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 brak-
ing distance will in crease. 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.
■
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.

Stopping the hybrid system WARNING■
Stopping the hybrid system in an
emergency ●
If you want to stop the hybrid system in
an emergency while driving the vehi-
cle, press and hold the power switch
for more than 2 seconds, or press it
briefly 3 times or more in succession.
( → P.420)
However, do not touch the power
switch while driving except in an emer-
gency. Turning the hybrid system 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. ●
If the power switch is operated while
the vehicle is running, a warning mes-
sage will be shown on the multi-infor-
mation display and a buzzer sounds. ●
