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.

2-1. Driving procedures
IS250/220d/200d_EE
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.

If the engine does not start
The engine immobilizer system may not have been deactivated. (P. 9 6 )
When the steering lock cannot be released
When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional, immediately.
Auto power off function
If the vehicle is left in ACCESSORY mode for more than an hour with the
shift lever in P (vehicles with an automatic transmission), the “ENGINE
START STOP” switch will automatically turn OFF.

CAUTION
When starting the engine
Always start the engine while sitting in the driver's seat. Do not press the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
push and hold the “ENGINE START STOP” switch for more than 3 sec-
onds.
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. 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.
NOTICE
To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or
IGNITION ON mode for long periods without the engine running.
When starting the engine
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

2-4. Using other driving systems
IS250/220d/200d_EE
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and should
not be relied upon too heavily when operating the vehicle.
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface.
Brake assist
Generates an increased level of braking force after the brake pedal
is depressed, when the system detects a panic stop situation.
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
TRC (Traction Control)
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
Hill-start assist control (vehicles with an automatic transmis-
sion)
Helps to prevent the vehicle from rolling backward when starting
on an incline or slippery slope.
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel.
PCS (Pre-Crash Safety System) (if equipped)
P. 230
VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, TRC, VSC,
hill-start assist control, and EPS systems.
Helps to maintain vehicle stability when swerving on slippery road
