1293-4. Adjusting the steering wheel and mirrors
3
Before driving
■Using automatic mode in cold weather
(power type)
When automatic mode is used in cold
weather, the door mirror could freeze up
and automatic stowing and return may not
be possible. In this case, remove any ice and
snow from the door mirror, then either
operate the mirror using manual mode or
move the mirror by hand.
■Customization
The automatic mirror fo lding and extending
operation can be changed.
(Customizable features: P.420)
When the mirror select switch is in the
“L” or “R” position, the outside rear
view mirrors will automatically angle
downwards when the vehicle is revers-
ing in order to give a better view of the
ground.
To disable this function, move the mir-
ror select switch to the neutral position
(between “L” or “R”).
■Adjusting the mirror angle when
the vehicle is reversing
With the shift lever in R, adjust the mir-
ror angle at a desired position. The
adjusted angle will be memorized and
the mirror will automatically tilt to the
memorized angle whenever the shift
lever is shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with th e shift lever in other
than R). Therefore, if the normal position is
changed after adjustment, the tilt position
will also change.
When the normal position is changed,
readjust the angle in reversing.
WARNING
■When a mirror is moving
To avoid personal injury and mirror mal-
function, be careful not to get your hand
caught by the moving mirror.

set with the brake pedal depressed,
and then shift the shift lever to D.
2 Release the brake pedal and gently
depress the accelerator pedal.
3 Release the parking brake.
■When starting off on a uphill
The hill-start assist control will activate.
(  P.248)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are simi-
lar to conventional vehicles, and it is neces-
sary to refrain from activities such as
sudden acceleration. ( P.252)
■Coasting (Auto Glide Control)
When Eco drive mode is selected, under
certain conditions, Auto Glide Control will
operate automatically and allow the vehicle
coast, enhancing fuel economy. ( P.214)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be reduced, the windows
may become fogged-up, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating
properly.
■Restraining the hybrid system output
(Brake Override System)
●When the accelerato r and brake pedals
are depressed at the same time, the
hybrid system output may be restrained.
●A warning message is displayed on the
multi-information display while the sys-
tem is operating. ( P.367)
Driving the vehicle
The following procedures should be
observed to ensure safe driving:
Driving procedure

1384-1. 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
vehicle in the normal way: P.358
●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.152)
●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 fail-
ure, 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,
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
control 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 transmission
and may result in a loss of vehicle con-
trol.
●Do not shift the shift lever 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 lever to a driving
position while the vehicle is moving
backward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.
●Shifting the shift lever to N while the
vehicle is moving will disengage the
hybrid system. Engine braking is not
available when N is selected.
●Be careful not to shift the shift lever
with the accelerator pedal depressed.
Shifting the shift lever to a gear other
than P or N may lead to unexpected
rapid acceleration of the vehicle that
may cause an accident and result in
death or serious injury.

1404-1. Before driving
WARNING
■When taking a nap in the vehicle
Always turn the hybrid system off. Oth-
erwise, 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 ve hicle, leading to
death or a serious health hazard.
■When braking
●When the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause
one side of the vehicle to brake differ-
ently than the other side. Also, the
parking brake may not securely hold
the vehicle.
●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 increase. 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 dis-
tance will increase. Have your brakes
fixed immediately.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and
brake pedals at the same time while
driving, as this may restrain the hybrid
system 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.
■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.
■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
brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat
tire ( P.379)
■When encountering flooded roads
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-

shift lever to N and press the power
switch shortly and firmly.
■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the hybrid system.
●Do not leave the vehicle with the
hybrid system operating for a long
time. If such a situation cannot be
avoided, park the vehicle in an open
space and ensure that exhaust fumes
do not enter the vehicle interior.
●Do not leave the hybrid system oper-
ating in an area with snow build-up, or
where it is snowing. If snowbanks build
up around the vehicle while the hybrid
system is operating, exhaust gases
may collect and enter the vehicle.
