LX570_OM_OM60L21U_(U) For your information Main Owner’s Manual Please note that this manual applies to all models and explains all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. How-
ever, because of the Lexus policy of contin ual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle sh own in the illustration may differ from
your vehicle in terms of color and equipment.
Noise from under vehicle 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 the sound of a fuel evaporation
leakage check and, it does not indicate a malfunction.
Accessories, spare parts and modification of your Lexus A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage they may cause to, or adverse effect they may have on, your
Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification
with non-genuine Lexus products could affect its performance, safety or durability,
and may even violate governmental regula tions. In addition, damage or perfor-
mance problems resulting from the modi fication may not be covered under war-
ranty.

421-2. Opening, closing and locking the doors
LX570_OM_OM60L21U_(U) ■
To operate the system properly
Make sure to carry the electronic key wh en operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected corr ectly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not function.) ■
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 back door is locked or unlocked.
• The electronic key is on the instrument panel, floor or in the glove box when
the engine is started or “ENGINE ST ART STOP” switch modes are changed.●
Do not leave the electronic key on top of the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the an tenna outside the cabin and the door will
become lockable from the outside, poss ibly trapping the electronic key inside
the vehicle. ●
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 pre-
vent the doors from being unlocked. In this case, return the door handle to the
original position and check that the d oors unlock before pulling the door han-
dle.

641-2. Opening, closing and locking the doors
LX570_OM_OM60L21U_(U) CAUTION■
Power back door
Observe the following precautions when operating the power back door.
Failure to do so may cause death or serious injury. ●
Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught. ●
If anyone is in the vicinity, make sure th ey are safe and let them know that the back
door is about to open or close. ●
If the power back door system is turned off with the main switch while the back
door is operating automatically, the automatic operation is stopped. The back
door then has to be operated manually. Take extra care when on an incline, as the
back door may open or close unexpectedly. ●
If the operating conditions of the power back door are no longer met, a buzzer
may sound and the back door may stop opening or closing. The back door then
has to be operated manually. Take extra ca re when on an incline, as the back door
may open or close abruptly. ●
On an incline, the back door may suddenl y shut after it opens. Make sure the
back door is fully open and secure. ●
In the following situations, the power b ack door may detect an abnormality and
automatic operation may be stopped. In this case, the back door has to be oper-
ated manually. Take extra care when on an incline, as the back door may open or
close abruptly.
• When the back door contacts an obstacle
• When the battery voltage suddenly drops, such as when the “ENGINE
START STOP” switch is turned to the IGNITION ON mode or the engine is
started during automatic operation●
If a bicycle carrier or similar heavy object is attached to the back door, the power
back door may not operate, causing itself to malfunction, or the back door may
suddenly shut again after being opened, causing someone’s hands, head or neck
to be caught and injured. When installing an accessory part to the back door,
using a genuine Lexus part is recommended.●
In cases such as when replacing tires, ma ke sure to turn off the power back door
main switch. Failure to do so may cause the back door to operate unintentionally
if the power back door switch is accidentally touched, resulting in hands and fin-
gers being caught and injured.

1682-1. Driving procedures
LX570_OM_OM60L21U_(U) CAUTION ●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases ca n be extremely hot. This may cause a
fire if there is any flammable material nearby. ●
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 back door is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and an acci-
dent, resulting in death or a serious health hazard. Have the vehicle inspected by
your Lexus deal er immediately.●
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 control. ●
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 control. ●
Do not shift the shift lever to “D” while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control. ●
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. ●
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 emergency, such as if it becomes impossible to stop
the vehicle in the normal way:  P. 8 7 8●
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. 1 8 0 )

When driving
LX570_OM_OM60L21U_(U) CAUTION ●
When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backwa rd 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 crossing rivers, turn off height co ntrol after putting the vehicle height in
high mode, and drive at 18 mph (30 km/h) or less. Otherwise the vehicle height
may change due to the automatic leveling function, resulting in an accident.
(  P. 3 1 8 )■
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 acceleration, engine braking due to shift changing, or changes in engine
speed could cause the vehicle to skid, resulting in an accident. ●
After driving through a pudd le, lightly depress the brak e 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.

1702-1. Driving procedures
LX570_OM_OM60L21U_(U) CAUTION■
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. ■
If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The rotor damage can 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
that of the brake discs are exceeded. ■
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 sud-
denly 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 no t enter the vehicle interior.●
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the en gine is running, 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 backward, 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.

1722-1. Driving procedures
LX570_OM_OM60L21U_(U) CAUTION■
Exhaust gases
Exhaust gases include harmfu l carbon monoxide (CO) th at 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 fi re due to abnormal engine overheating.
Additionally, if the vehicle is parked in a poorly ventilated area, exhaust gases may
collect and enter the vehicle, leading to death or a serious health hazard. ■
When braking the vehicle ●
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle. ●
If the power brake assist function 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 braking distance will increase.
Have your brakes fixed immediately. ●
Do not pump the brake pedal if the engine stalls.
Each push on the 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 the braking distance will increase.
Have your brakes fixed immediately.
