Lexus parking assist-sensor
The distance to obstacles measured by the sensors is communicated
via the multi-information display and a buzzer when parallel parking
or maneuvering into a garage. Always check the surrounding area
when using this system.

Sensor detection information
Certain vehicle conditions and the surrounding environment may affect
the ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle

CAUTION
Caution when using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
Do not use the sensor at speeds in excess of 10 km/h (6 mph).
Do not attach any accessories within the sensor range.
NOTICE
Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

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.

When driving
IS250/220d/200d_EEImportant points regarding turning
The wheels of the trailer will travel closer to the inside of the
curve than the wheels of the vehicle. To make allowance for this,
take the turns wider than you would normally.
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and
strong crosswinds will affect handling. The vehicle may also be
rocked by passing buses or large trucks. Frequently check
behind when moving alongside such vehicles. As soon as such
vehicle movement occurs, immediately start to decelerate
smoothly by slowly applying the brakes. Always steer the vehi-
cle straight ahead while braking.
Passing other vehicles
Consider the total combined length of your vehicle and trailer
and ensure that the vehicle-to-vehicle distance is sufficient
before executing lane changes.
Transmission information
Refrain from driving in 6 (manual transmission) or 4 range in S
mode (automatic transmission) to maintain the effectiveness of
the engine brake and the charge performance of electrical com-
ponents.
If the engine overheats...
Towing a loaded trailer up a long steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If
the engine coolant temperature gauge indicates that the engine is
overheating, turn the air conditioning off immediately, leave the
road and stop the vehicle in a safe place. (P. 525)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever
to P for automatic transmissions, and 1 or R for manual trans-
missions.
