4-1.Before driving
■Starting the engine
 P.128
■Driving
1 With the brake pedal depressed,
shift the shift lever to D. ( P.132)
2 Release the parking brake.
(P.137)
3 Gradually release the brake pedal
and gently depress the accelerator
pedal to accelerate the vehicle.
■Stopping
1 With the shift lever in D, depress the
brake pedal.
2 If necessary, set the parking brake.
If the vehicle is to be stopped for an
extended period of time, shift the shift lever
to P or N. ( P.132)
■Parking the vehicle
1 With the shift lever in D, depress the
brake pedal.
2 Set the parking brake ( P.137),
and shift the shift lever to P
( P.132).
3 Press the engine switch to stop the
engine.
4 Lock the door, making sure that you
have the electronic key on your
person.
If parking on a hill, block the wheels as
needed.
■Starting off on a steep uphill
1 Make sure that the parking brake is
set and shift the shift lever to D.
2 Gently depress the accelerator
pedal.
3 Release the parking brake.
■When starting off on an uphill
The hill-start assist control will activate.
(  P.200)
■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 prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden
acceleration.
●The vehicle is judged to be driving uphill
or downhill
●When the accelerato r pedal is released
●When the brake pedal is depressed while
sport mode is selected
■Restraining the engine output (Brake
Override System)
●When the accelerator and brake pedals
are depressed at the same time, the
engine output may be restrained.
●A warning message is displayed on the
multi-information display while the sys-
tem is operating.
Driving the vehicle
The following procedures should be
observed to ensure safe driving:
Driving procedure

1204-1. Before driving
WARNING
●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 pull
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.294
●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.132)
●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 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 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 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 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.
●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.
●Moving the shift lever to N while the
vehicle is moving will disengage the
engine from the transmission. Engine
braking is not available when N is
selected.

1264-1. Before driving
■Total load capacity and seating capacity
These details are also described on the tire
and loading information label. ( P.279)
WARNING
●Do not place cargo or luggage in or on
the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
• In front of the Center Display
●Secure all items in the occupant com-
partment.
■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.342
Total load capacity means the com-
bined weight of occupants, cargo
and luggage.
 Seating capacity: P.342
Seating capacity means the maxi-
mum number of occupants whose
estimated average weight is 150 lb.
(68 kg) per person.
 Towing capacity
Lexus does not recommend towing
a trailer with your vehicle.
 Cargo capacity
Cargo capacity may increase or
decrease depending on the weight
and the number of occupants.
WARNING
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires,
but also degrade steering and braking
ability, resulting in an accident.

1584-5. Using the driving support systems
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe
driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system
instead of normal braking operations
under any circumstances. This system
will not prevent collisions or lessen col-
lision damage or injury in every situa-
tion. Do not overly rely on this system.
Failure to do so may lead to an acci-
dent, resulting in death or serious
injury.
●Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no possi-
bility of a collision:
P.160
• Conditions under which the system may not operate properly:
P.162
●Do not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.
●If the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seco nds. Depress the
brake pedal as necessary.
●The pre-collision braking function may
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and pos-
sibly prevent the pre-collision braking
function from operating.
●In some situations, while the pre-colli-
sion braking function is operating,
operation of the function may be can-
celed if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
●If the brake pedal is being depressed,
the system may determine that the
driver is taking evasive action and pos-
sibly delay the operat ion timing of the
pre-collision braking function.
■When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another
vehicle
●When transporting the vehicle via
truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift with
the engine running and the tires are
allowed to rotate freely
●When inspecting the vehicle using a
drum tester such as a chassis dyna-
mometer or speedometer tester, or
when using an on vehicle wheel bal-
ancer
●When a strong impact is applied to the
front bumper or front grille, due to an
accident or other reasons
