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.

1732-1. Driving procedures

When driving
LX570_OM_OM60L96U_(U) CAUTION■
When the vehicle is parked ●
Do not leave glasses, cigarette 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 sh ifted completely. The transfer mode dis-
engages both the front and rear driveshafts from the powertrain and allows the
vehicle to move regardless of the 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. 332)●
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 ar ea 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 vehicle. This may lead to death or a seri-
ous health hazard.

1742-1. Driving procedures
LX570_OM_OM60L96U_(U) 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 ex haust 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 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 shar p turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, th e braking distance will increase.
Have your brakes fixed immediately. ●
Do not pump the brake peda l 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.
