Before driving
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the
system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear bumper center when the trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in the glove box when the engine is started or “ENGINE START STOP” switch
modes are changed.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●Even if the electronic key is not inside th e vehicle, it may be possible to start the
engine if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
●Gripping the door handle when wearing a glove may not unlock the door.
●If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless re mote control to unlock the doors.)
●A sudden approach to the effective range or door handle operation may prevent
the doors from being unlocked. In this case, return the door handle to the original
position and check that the doors unlock before pulling the door handle again.
■When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m) of
the vehicle.
■Security feature

1
Before driving
■Operating the power windows after turning the “ENGINE START STOP” switch
OFF
The power windows can be operated for approximately 45 seconds even after the
“ENGINE START STOP” switch is switched to ACCESSORY mode or turned
OFF. They cannot, however, be operated once either front door is opened.
■Jam protection function
If an object becomes caught between th e window and the window frame, window
travel is stopped and the window is opened slightly.
■When the battery is disconnected
The power windows must be initialized in order to ensure proper operation. (Per-
form for each window with the switch for each seat.)
Open the window halfway.
Fully close the window by pulling the switch up and continue holding the
switch for one second.
The indicator on the switch changes from a flashing pattern to being on when initial
settings are complete.
■Customization that can be configured at Lexus dealer
Settings (e.g. linked door lock operation) can be changed.
(Customizable features  P. 4 2 4 )
CAUTION
■Closing the windows
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Check to make sure that all passengers do not have any part of their body in a
position where it could be caught when a window is being operated.
●Do not allow children to operate the power windows.
Closing a power window on someone can cause serious injury, and in some
instances, even death.
■Jam protection function
●Never try jamming any part of your body to activate the jam protection function
intentionally.
●The jam protection function may not work if something gets caught just before
the window fully closes.

When driving
■Starting off on a hill
Hill-start assist control will operate. (P. 166)
■Driving in the rain
●Drive carefully when it is raining, becaus e visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, be cause the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between th e tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoes periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. ( P. 4 0 1 )
■Normal characteristics after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound coming
from under the vehicle for several minutes. This is because fuel evaporation leakage
check is performed. It does not indicate a malfunction.

2-1. Driving procedures
CAUTION
■When starting off
To prevent the vehicle from creeping forward, keep the brake pedal firmly
depressed when shifting the shift lever.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may le ad to an accident that could result in
death or serious injury.
• When backing up, you may twist your bo dy 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, allowing you to depress the brake and accelerator pedals prop-
erly.
• 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 acci-
dent.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●Do not let the vehicle roll backwards while the shift lever is in a driving position, 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 perfor-
mance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed. Large amounts of exhaust in the vehicle can cause driver
drowsiness and an accident, resulting in death or a serious health hazard. Have
the vehicle inspected by your Lexus dealer immediately.
●Do not under any circumstances shift the sh ift lever to P, R or N while the vehicle
is moving.
Doing so can cause significant damage to the transmission system and may result
in a loss of vehicle control.
●Do not shift the shift lever to N while the vehicle is moving.
Doing so may cause the engine brake to not operate properly and lead to an
accident.

When driving
CAUTION
●Do not turn the engine off while driving.
The power steering and brake booster systems will not operate properly if the
engine is not running.
●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 effec-
tiveness. (P. 120, 122)
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits 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 surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehi cle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may cause the vehicl e to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on on ly one side are wet and not functioning
properly, steering control may be af fected, resulting in an accident.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.

2-1. Driving procedures
CAUTION
■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 suddenly
and unexpectedly, and may cause an accident.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do not enter the vehicle interior.
●Always keep a foot on the brake pedal while the engine is running to prevent an
accident caused by the vehicle moving.
●To prevent the vehicle from moving an d causing an accident, apply the brake
pedal or parking brake when stopping the vehicle on a hill.
■When the vehicle is parked
●Do not leave glasses, cigarett e lighters, spray cans, or soft drink cans in the vehi-
cle 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 plastic material of eye 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 com-
ponents.
●Always apply the parking brake, shift the shift lever to P, stop the engine and lock
the vehicle.
Do not leave the vehicle unattend ed while the engine is running.
●Do not touch the exhaust pipes or rear bumper exhaust diffusers while the engine
is running or immediately af ter turning the engine off.
Doing so may cause burns.
●Do not leave the engine running in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the engine is running,
exhaust gases may collect and enter the vehi cle. This may lead to death or a seri-
ous health hazard.

When driving
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and odor-
less. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated ar ea, stop the engine. In a closed area, such
as a garage, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
●The exhaust should be checked occasionally. If there is a hole or crack caused by
corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehi-
cle inspected and repaired by your Lexus dealer. Failure to do so may allow
exhaust gases to enter the vehicle, result ing in death or a serious health hazard.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift lever or
depress the accelerator pedal, which 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, lead ing to death or a serious health hazard.
■When braking the vehicle
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 2 individual hydraulic systems: if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
