When driving
nRadar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
nWarning lights and messages for dynamic radar cruise control
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. ( →P. 5 5 1 )
nApproach warning
In the following instances, there is a possibility that the approach warnings will not
occur:
lWhen the speed of the vehicle ahead matches or exceeds your vehicle speed
lWhen the vehicle ahead is traveling at an extremely slow speed
lImmediately after the cruise control speed was set
lAt the instant the accelerator is applied

nCertification
For vehicles sold in U.S.A.
FCC ID: HYQDNMWR005
This device complies with Part 15 of the FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
FCC WARNING
Changes or modifications not expressly approved by the party responsible for
compliance could void the use’s authority to operate the equipment.
Radio frequency radiation exposure Information:
This equipment complies with FCC radiation exposure limits set forth for an uncon-
trolled environment.
This equipment should be installed and operated with minimum distance of 20 cm
between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
For vehicles sold in Canada
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interfer-
ence that may cause undesired operation of the device.
CAUTION
nBefore using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropri-
ate, adjust the vehicle speed, as well as the distance between your vehicle and vehi-
cles ahead by applying the brakes etc.

2-4. Using other driving systems
CAUTION
nSituations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
lIn heavy traffic
lOn roads with sharp bends
lOn winding roads
lOn slippery roads, such as those covered with rain, ice and snow
lOn steep downhills, or where there are sudden changes between sharp up and
down gradients
lAt entrances to expressways
lWhen weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
lWhen a buzzer is heard often
lWhen your vehicle is towing anything
nWhen the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning ( →P. 213) will not be activated, and an accident may result.
lVehicles that cut in suddenly
lVehicles traveling at low speeds
lVehicles that are not moving
lVehicles with small rear ends (trailers with no load on board etc.)
lMotorcycles traveling in the same lane

2-4. Using other driving systems
CAUTION
nWhen the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
nWhen the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC/VSC systems off unless necessary.
nReplacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
nHandling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause a system malfunction.

2-4. Using other driving systems
When the system is activated in the situations described above, there is also a possi-
bility 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 it.
nObstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts.
nWhen there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( →P. 535, 545)

NOTICE
nRepairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
nFitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.

Radio Frequency Radiation Exposure. This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equipment and meets the FCC radio fre-
quency (RF) Exposure Guidelines in Supplement C to OET65. This equipment has
very low levels of RF energy that it deemed to comply without maximum permissive
exposure evaluation (MPE). But it is desirable that it should be installed and oper-
ated with at least 7.9 in. (20 cm) and more between the radiator and person’s body
(excluding extremities: hands, wrists, feet and legs).
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
nCaution while driving
Do not connect portable players or operate the controls.
NOTICE
nTo prevent damage to portable players
Do not leave portable players in the vehicle. The temperature inside the vehicle
may become high, resulting in damage to the player.
