Driving
■Restraining sudden start (Drive-Start
Control)
●When the following unusual operation is
performed, the hybrid system output may
be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D
includes S) with the accelerator pedal
depressed, a warning message appears
on the multi-information display and
head-up display (if equipped). If a warn-
ing message is shown on the multi-infor-
mation display and head-up display, read
the message and follow the instructions.
• When the accelerator pedal is depressed
too much while the vehicle is in reverse.
●While Drive-Start Control is being acti-
vated, your vehicle may have trouble
escaping from the mud or fresh snow. In
such case, deactivate TRAC ( P.257)
to cancel Drive- Start Control so that the
vehicle may become able to escape from
the mud or fresh snow.
■Breaking in your new Lexus
To extend the life of the vehicle, observing
the following precautions is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign
country
Comply with the relevant vehicle registra-
tion laws and confirm the availability of the
correct fuel. ( P.417)
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■When starting the vehicle
Always keep your foot on the brake
pedal while stopped with the “READY”
indicator is illuminated. 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 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.
●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 though
the vehicle is equipped with the vehicle
proximity notification system, 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.

1544-1. Before driving
WARNING
●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.378
●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.
●AWD models: Do not drive the vehicle
off-road.
This is not an AWD vehicle designed
for off-road driving. Proceed with all
due caution if it becomes unavoidable
to drive off-road.
●Do not drive across a river or through
other bodies of water.
This may cause electric/electronic
components to short circuit, damage
the hybrid system or cause other seri-
ous damage to 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 capa-
bility tires or not befo re 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,
resulting in an accident.
●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 lever
●Do not let the vehicle roll backward
while the shift lever is in a driving posi-
tion, or roll forward while the shift lever
is in R.
Doing so may result in an accident or
damage to the vehicle.
●Do not shift the shif t lever to P while
the vehicle is moving.
Doing so can damage the hybrid trans-
mission and may result in a loss of vehi-
cle control.
●Do not shift the shift lever to R while
the vehicle is moving forward.
Doing so can damage the hybrid trans-
mission and may result in a loss of vehi-
cle control.

Driving
WARNING
●Do not shift the shift lever to a driving
position while the vehicle is moving
backward.
Doing so can damage the hybrid trans-
mission and may result in a loss of vehi-
cle control.
●Shifting the shift lever to N while the
vehicle is moving will disengage the
hybrid system. Engine braking is not
available with the hybrid system disen-
gaged.
●Be careful not to shift the shift lever
with the accelerator pedal depressed.
Shifting the shift lever to any position
other than P or N may lead to unex-
pected rapid acceleration of the vehi-
cle that may cause an accident and
result in death or serious injury.
■If you hear a squealing or scraping
noise (brake pad wear limit indica-
tors)
Have the brake pads checked and
replaced by your Lexus dealer as soon as
possible. Rotor damage may result if the
pads are not replaced when needed.
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 depress the accelerator pedal
unnecessarily.
If the shift lever is in any position other
than P or N, the vehicle may acceler-
ate suddenly and unexpectedly, caus-
ing an accident.
●In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while
stopped with the “READY” indicator is
illuminated, and apply the parking
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 cigare tte 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 panel 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.
