Before driving
LX570_OM_OM60L96U_(U) ■
To operate the system properly
Make sure to carry the electronic key when 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 cond ition of the electronic key, the key may
not be detected correctly and the system may not oper ate 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 antenna outside the cabin and the door will
become lockable from the outside, possibly 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 the 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. (T he doors will automatically be locked after
approximately 60 seconds if the doors are not open ed and closed.)●
Gripping the door handle when wear ing 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 remote control to unlock the doors.) ●
A sudden approach to the effective ra nge or door handle operation may pre-
vent the doors from being unlocked. In th is case, return the door handle to the
original position and check that the do ors unlock before pulling the door han-
dle.

641-2. Opening, closing and locking the doors
LX570_OM_OM60L96U_(U) CAUTION■
Power back door
Observe the following precautions when operating the power back door.
Failure to do so may caus e 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 they 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 care when on an incline, as the back
door may open or close abruptly.●
On an incline, the back door may sudden ly shut after it opens. Make sure the
back door is fully open and secure. ●
In the following situations, the power ba ck door may detect an abnormality and
automatic operation may be stopped. In th is 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

8311-3. Adjustable components (seats, mirrors, steering wheel)
Before driving
LX570_OM_OM60L96U_(U) Driving position memory system Your preferred driving position (the po sition of the driver’s seat, steering
wheel and outside rear view mirrors) can be entered into the computer’s
memory and recalled with the touch of a button. It is also possible to set this
function to activate automatica lly when the doors are unlocked.
Three different driving positions can be entered into memory.

1702-1. Driving procedures
LX570_OM_OM60L96U_(U) CAUTION ●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can 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 heal th hazard. Have the vehicle inspected by
your Lexus dealer 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 vehicl e 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. 883●
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. 182)

When driving
LX570_OM_OM60L96U_(U) CAUTION ●
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 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. 320)■
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 shifting, or changes in engine speed
could cause the vehicle to skid, resulting in an accident. ●
After driving through a puddle, lightly de press 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 only one side are wet and not func-
tioning properly, steering control may be affected, resulting in an accident.

1722-1. Driving procedures
LX570_OM_OM60L96U_(U) CAUTION■
When shifting the shift lever
Be careful not to shift th e shift lever with the acc elerator 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 replace 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 engi ne 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.
