When driving
LX570_OM_OM60L21U_(U) Starting on a steep uphill
Firmly set the parking brake and shift the shift lever to “D”.
Gently depress the accelerator pedal.
Release the parking brake.■
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.■
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 accelerator pedal is released ●
When the brake pedal is depressed while power mode is selected (  P. 181)■
Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe: ●
For the first 200 miles (300 km):
Avoid sudden stops. ●
For the first 500 miles (800 km):
Do not tow a trailer. ●
For the first 1000 miles (1600 km):

When driving
LX570_OM_OM60L21U_(U) ■
When turning off the engine
Emission system operating sounds may cont inue for a short time after the engine is
turned off. This is not a malfunction, and helps to ensure optimal performance of the
emission system.
CAUTION■
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running.
This prevents the vehicle from creeping. ■
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 accelerato r 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.

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.

When driving
LX570_OM_OM60L21U_(U) CAUTION■
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.
Failure to do 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.●
If the shift lever is moved before the low speed four-wheel drive indicator turns
on/off, the transfer mode may not be shifted completely. The transfer mode disen-
gages both the front and rear driveshafts from the powertrain and allows the vehi-
cle to move regardless of th e shift position. (At this time, the indicator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in “P”.
You or someone else could be seriously injured. You must complete the shifting of
the transfer mode. (  P. 3 3 0 )●
Do not touch the exhaust pipe while the engine is running or immediately after
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.

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.

1742-1. Driving procedures
LX570_OM_OM60L21U_(U) NOTICE■
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brak e pedal to slow down the vehicle.●
It may be difficult to control your vehicle. ●
The vehicle will make abnormal sounds. ●
The vehicle will behave abnormally.
Replace a flat tire with a new one. (  P. 8 5 4 )■
When encountering flooded roads

following serious damage to the vehicle. ●
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 following.●
Brake function ●
Changes in quantity and quality of oil an d fluid used for the engine, transmission,
transfer, differentials, etc. ●
Lubricant condition for the propeller shaft, bearings and suspension joints (where
