When driving
IS250/220d/200d_EE
CAUTION
On vehicles with an automatic transmission, 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 (vehicles with an automatic transmission)
or 1 (vehicles with a manual transmission) 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. 5 3 1
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
effectiveness. (P. 161)
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 bod-
ies are not outside the vehicle, as this may result in death or serious injury.

2-1. Driving procedures
IS250/220d/200d_EE
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
Sudden changes in engine speed, such as engine braking caused by up-
shifting or down-shifting, may cause the vehicle to skid, resulting in an
accident.
After driving through a puddle, lightly depress 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 functioning properly, steering control may be affected, result-
ing in an accident.
When shifting the shift lever
With automatic transmission vehicles, 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 noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, as soon as
possible.
Rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of brake pad and disc wear allow
enhanced front braking power. As a result, the discs may wear more quickly
than conventional brake discs. Therefore, when replacing the brake pads,
Lexus recommends that you also have the thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those 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 (vehicles with an automatic trans-
mission only) or N the vehicle may accelerate suddenly 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 not enter the vehicle interior.

IS250/220d/200d_EE
CAUTION
With automatic transmission: In order to prevent accidents due to the
vehicle rolling away, always keep depressing the brake pedal while the
engine 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 the vehicle is parked
Do not leave glasses, cigarette lighters, spray 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 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 vehi-
cle's electrical components.
Always apply the parking brake, shift the shift lever to P (vehicles with an
automatic transmission only), stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
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 vehicle. This may lead to
death or a serious health hazard.

NOTICE
When driving the vehicle
Do not depress the accelerator and brake pedals at the same time during
driving. If the brake pedal is depressed while driving with the accelerator
pedal depressed, driving torque may be restrained.
With automatic transmission vehicles
Do not use the accelerator pedal or depress the accelerator and brake ped-
als together to hold the vehicle on a hill.
With manual transmission vehicles
Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
Do not use any gears other than the first gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
Do not use the clutch to hold the vehicle when stopping on an uphill
grade.
Doing so may damage the clutch.
When parking the vehicle
With automatic transmission vehicles, always put the shift lever in P. Failure
to do so may cause the vehicle to move or the vehicle may accelerate sud-
denly 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
a long 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.
IS220d and IS200d: Make sure to idle the engine immediately after high-
speed driving or hill climbing. Stop the engine only after the turbocharger
has cooled down.
Failure to do so may cause damage to the turbocharger.
