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

When driving
IS250/220d/200d_EE
When a billboard or other metallic structure appears to be in the vehi-
cle’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.
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.

Cargo and luggage
CAUTION
Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk.
Receptacles containing gasoline
Aerosol cans
Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
Do not place cargo or luggage in or on the following locations as the item
may get under the clutch, brake or accelerator pedal and prevent the ped-
als from being depressed properly, block the driver’s vision, or hit the
driver or passengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Package tray
• Instrument panel
• Dashboard
Secure all items in the occupant compartment, as they may shift and injure
someone during sudden braking, sudden swerving or an accident.
Take notice of the following information about storage precautions,
cargo capacity and load.
Stow cargo and luggage in the trunk whenever possible.
Be sure all items are secured in place.
Be careful to keep the vehicle level. Placing the weight as far
forward as possible helps maintain vehicle balance.
For better fuel economy, do not carry unnecessary weight.

Selecting tire chains
Tire chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(3 mm [0.12 in.] in diameter)
Cross chain
(4 mm [0.16 in.] in diameter)
Regulations on the use of tire chains
Regulations regarding the use of tire chains vary according to
location and type of road. Always check local regulations before
installing chains.
Install the chains on the rear tires.
When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed
suitable to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to P (automatic
transmission) or 1 or R (manual transmission) without setting
the parking brake. The parking brake may freeze up, prevent-
ing it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.

Guidance
Your vehicle will handle differently when towing a trailer. In order
to avoid accident, death or serious injury, keep the following in
mind when towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection
between the trailer and lights after driving for a brief period as
well as before setting off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering wheel nearest to you and rotate clockwise to turn the
trailer left or counterclockwise to turn right. Always rotate
gradually to prevent steering error. Have someone guide you
when reversing to lessen the risk of accident.
Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle run-
ning ahead of you should be equivalent to or greater than the
combined length of your vehicle and trailer. Avoid sudden brak-
ing that may cause skidding. Otherwise, the vehicle may spin
out of control. This is especially true when driving on wet or
slippery road surfaces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer col-
liding with your vehicle. Decelerate well in advance when
approaching turns and take them slowly and carefully to avoid
sudden braking.

3-1. Using the air conditioning system and defogger
IS250/220d/200d_EE
Automatic mode for air intake control (IS250 only)
In automatic mode, the system detects exhaust gas and other pollutants and
automatically switches between outside air and recirculated air modes.
Pollen removal mode
In order to prevent the windshield from fogging up when the outside air
is cold, the following may occur.
• Outside air mode does not switch to .
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
In rainy weather, the windows may fog up. Press .
Air conditioning odors
During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of
time immediately after the air conditioning system is started in auto-
matic mode.
CAUTION
To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, blocking
your vision.
NOTICE
To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
