■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes peri odically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( →P. 587)
■Idling time before engine stop (IS200t)
To prevent damage to the turbocharger, allow the engine to idle immediately after high-
load driving.
Driving conditionIdling time
Normal city driving or high-spe ed driving (at the highway speed
limit or recommended speed)
Not necessary
Steep hill driving, continuous driv ing (race track driving etc.), or

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the shift lever is any position other than P or N, the vehicle may accelerate suddenly
and unexpectedly, causing an accident.
●In order to prevent accidents due to the ve hicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake as neces-
sary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, alwa ys 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 the vehicle is parked
●Do not leave glasses, cigarette lighters, sp ray cans, or soft drink cans in the vehicle
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 cau se the plastic lenses and plastic mate-
rial of 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 circui t in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as
the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windsh ield or windows. Do not place containers
such as air fresheners on th e instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, ca using a fire in the vehicle.
●Do not leave a door or window open if th e curved glass is coated with a metallized
film such as a silver-colored one. Reflecte d sunlight may cause the glass to act as a
lens, causing a fire.
●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 vehicle is parked with the shift leve r in P but the parking brake is not set, the
vehicle may start to move, possibly leading to an accident.
●Do not touch the exhaust pipes while the engine is running or immediately after turn-
ing the engine off.
Doing so may cause burns.

1644-1. Before driving
IS350/300/200t_U (OM53D76U)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to engine over-
heating. Additionally, if the ve hicle 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
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this 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, bu t the brake pedal should be depressed more
firmly than usual. Also, the braking distan ce will increase. Have your brakes fixed
immediately.
●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 hy draulic 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 bra king distance will increase.
Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessive ly when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage the driveline components or propel the vehi-
cle forward or backward, causing an accident.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as
this may restrain the engine output.
●Do not use the accelerator pedal or depre ss the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake, and shift the sh ift lever to P. Failure to do so may cause
the vehicle to move or the vehicle may acce lerate suddenly if the accelerator pedal is
accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.
●IS200t: Make sure to idle the engine imme diately after high-load driving. Stop the
engine only after the turb ocharger has cooled down.
Failure to do so may cause damage to the turbocharger.
■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 depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 546)
■When encountering flooded roads
Do not drive on a road that has flooded af ter heavy rain etc. Doing so may cause the
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 and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.
