When driving
IS F_EE
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because 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 the tires and the road sur-
face, preventing the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driv-
ing. This is due to automatic up-shifting control or down-shifting implemen-
tation to meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recom-
mended to observe:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
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 periodically or when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional, perform the bedding down.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the avail-
ability of the correct fuel. (P. 4 7 4 )

When driving
IS F_EE
CAUTION
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. 4 6 9
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. 153, 155)
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.
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.

IS F_EE
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 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.
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 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.
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.

IS F_EE
CAUTION
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 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 park-
ing brake may not securely hold the vehicle.
If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
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 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 braking distance becomes
longer.
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
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.
Do not use the accelerator pedal or depress the accelerator and brake ped-
als together to hold the vehicle on a hill.

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.
