Driving
• When the Lexus parking assist-sensor is turned off once and turned on again• When the engine switch
is turned off once and turned to IGNI- TION ON mode again
■If “Clean Parking Assist Sensor” is dis-played on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is removed from
the sensor, the system should return to nor- mal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may appear or an obstacle may not be detected.
If the sensor thaws out, the system should return to normal.
■If “Parking Assist Malfunction” or “Park-ing Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor- mation display
There is a malfunction and the device may not be working properly.
Have the vehicle inspected by any autho- rized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front and rear bumpers.
●Certain vehicle conditions and the sur-rounding 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.
(Wiping the sensors will resolve this problem.)• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is fro-
zen the screen may show an abnormal dis-
play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.• On an extremely bumpy road, on an
incline, on grav el, 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 sensor in the vicinity.• The sensor is splashed with water 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.
• The area directly under the bumpers is not detected.• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.• People may not be detected if they are
wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
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 particu-
lar attention to the following obstacles: • Wires, fences, ropes, etc.• Cotton, snow and other materials that
absorb sound waves • Sharply-angled objects•Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance may shorten, or detection may be impos-
sible. • Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the
obstacle will come within the sensor’s detection areas before the display is shown and the warning beep sounds.

■EPS, VGRS and DRS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be heard. This does not indicate a malfunction.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch
is turned off
●If only the TRC system is turned off, the
TRC will turn on when vehicle speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed increases.
■Secondary Collision Brake operating
conditions
The vehicle speed is approximately 10 km/h
(6 mph) or more and the airbag sensor detects a collision. (The Secondary Colli-sion Brake will not operate when the vehicle
speed is below approximately 10 km/h [6 mph].)
■Secondary Collision Brake automatic
cancellation
The Secondary Collision Brake is automati-
cally canceled in the following situations:
●The vehicle speed drops below approxi-
mately 10 km/h (6 mph)
●A certain amount of time elapses during
operation

■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends that maintenance service operations as well as
other inspections and repairs be carried out by authorized Lexus retailer or Lexus authorized repairer, or any reliable repair-
ers. For repairs and services covered by your warranty, please visit an authorized Lexus retailer or repairer, who will use gen-
uine Lexus parts in repairing any difficulties you may encounter. There can also be advantages in utilizing authorized Lexus
retailers or repairers for non-warranty repairs and services, as members of the Lexus network will be able to expertly assist
you with any difficulties you may encounter.
Your Lexus retailer or Lexus authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance on your vehicle reliably and economically due
to their experience with Lexus vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.
For details about maintenance items and
schedules, refer to the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are easy to
do yourself if you have a little mechanical
ability and a few basic automotive tools.
Note, however, that some maintenance
tasks require special tools and skills. These
are best performed by qualified techni-
cians. Even if you’re an experienced do-it-
yourself mechanic, we recommend that
repairs and maintenance be conducted by
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer. Any authorized Lexus retailer or
repairer will keep a record of maintenance,
which could be useful should you ever
require Warranty Service. Should you
choose to select a qualified and equipped
professional other than an authorized
Lexus repairer to service or maintain your
vehicle, we recommend that you request
that a record of maintenance be kept.
■Does your vehicle need repairs?
