When installing a child restraint system
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for the child restraint system installa-
tion.
When a junior seat is installed, always ensure that the shoulder belt is
positioned across the center of the child's shoulder. The belt should be
kept away from the child's neck, but not so that it could fall off the child's
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, choking or other serious injuries may result
in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
Make sure the outside rear seat head restraints are not in the folded posi-
tion.
Ensure that the belt and tab are securely locked and the seat belt is not
twisted.
Push and pull the child seat from side to side and forward to be sure it is
secure.
Follow all installation instructions provided by the child restraint system
manufacturer.
Never use a rear-facing child restraint
system on the front passenger seat
when the airbag manual on-off switch
is on.
(P. 135)
The force of the rapid inflation of the
front passenger airbag can cause death
or serious injury to children in the
event of an accident.
A warning label on the passenger side
instrument panel reminds you not to
install a rear-facing child restraint sys-
tem on the front passenger seat

CAUTION
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, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
Do not touch the exhaust pipes or rear bumper exhaust diffusers 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.
Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
If the vehicle is in a poorly ventilated area, 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 exhaust noise, be sure
to have the vehicle inspected and repaired by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional. Failure to
do so may allow exhaust gases to enter the vehicle, resulting in death or a
serious health hazard.

When driving
IS F_EE
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
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. 213
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
surfaces by controlling the brakes, engine output and steering assist.
When the F-sport mode total control switch is pressed, “Sport”
mode is activated. (P. 209)

2-4. Using other driving systems
IS F_EE
When passing an oncoming vehicle on a right-turn (right-hand drive
countries) or left-turn (left-hand drive countries)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle's line of travel.
When an overhead billboard or other metallic structure appears to be in
the vehicle’s direct line of travel due to driving on a hill.
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When driving on a bridge.
When the system is activated in the situations described above there is also a
possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 425,
431)
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.
