NOTE●Immediately after the vehicle starts moving after engine
start up, a whining sound of the motor will be heard from
the engine compartment. If the brake pedal is depressed at
that moment, a brake pedal pulsating is felt.
This pulsation is due to the self-diagnosis operation of the
ABS and does not indicate a malfunction.
●After driving on snowy roads, remove any snow and ice
which may have become adhered to the wheel areas.
When doing this, be careful not to damage the wheel
speed sensors (A) and cables located at each wheel on
vehicles equipped with an ABS.

To resume the set speed
E00609800271
If the speed memory has not been erased, resume the previ-
ously set speed by pulling the auto-speed control lever up
while driving at a speed of about 40 km/h (25 mph) or higher.
Under either of the following conditions, however, using the
switch does not allow you to resume the previously set speed.
In these situations, repeat the speed setting procedure:
●The ignition switch is turned OFF.
●The main switch is turned OFF.
Corner sensor system
*
E00615500039
This system operates when you are backing the vehicle. It uses
corner and back sensors to detect an obstacle and sounds a
buzzer to inform you of the approximate distance to the obsta-
cle.
CAUTION
!●The corner sensor system assists you in determining
the approximate distance between the vehicle and an
obstacle located behind the vehicle. It has limitations
in terms of detectable areas and objects, and may
not properly detect some objects. Therefore, do not
place excessive confidence in the corner sensor sys-
tem, and operate the vehicle as carefully as you
would a vehicle without this system.●Make sure to check the surroundings with your own
eyes to ensure safety. Do not operate the vehicle by
relying on the corner sensor system alone.

Obstacle detection areas
E00615600199
The detection areas of the corner and back sensors are limited
to those shown in the illustration. Moreover, the sensors are
unable to detect low or thin objects or objects near the rear
bumper. Thus, make sure to check the surroundings as you
operate the vehicle in a safe manner.Corner and back sensor locationsThere are two corner sensors (A) at the corners of the rear
bumper, and two back sensors (B) in the centre of the rear
bumper.
Corner sensor system detection areasDepending on whether the vehicle is equipped with a towbar,
you can change the corner sensor system between the standard
mode and the towbar mode. The towbar mode changes the sys-
tem to exclude the area in which the towbar is mounted from
the detection areas.
Vehicles without a towbar
The detection areas are within approximately 50 cm (A) from
the corner sensors, 100 cm (B) from the back sensors, and
60 cm (C) or less from the ground surface, excluding the area
approximately 10 cm (D) from the ground surface.

Vehicles with a towbar
The detection areas are within approximately 50 cm (A) from
the corner sensors, 100 cm (B) from the back sensors, and
60 cm (C) or less from the ground surface, excluding the area
approximately 10 cm (D) from the ground surface. The non-
detection areas (E) are within approximately 20 cm (F) from
the bumper.NOTE●If the rear bumper has been exposed to an impact, the cor-
ner or back sensors may fail and prevent the system from
functioning properly. We recommend you to have your
vehicle inspected.
●The sensors do not detect objects located in the area
directly below or near the bumper. If the height of an
object is lower than the mounted position of the corner or
back sensors, the sensors may not continue detecting it
even if they detected it initially.For information on how to change the detection areas, please
refer to “Changing the detection areas” on page 4-56.
CAUTION
!●The corner sensor system may not operate properly
under the following conditions:
• The sensors or surroundings are covered with ice,
snow, or mud.• The sensors are frozen.• The system receives ultrasonic noise from other
sources (the horns of other vehicles, motorcycle
engines, brakes, radios, pouring rain, splashing
water, tyre chains, etc.).• The sensors are extremely hot or cold (while the
vehicle is parked for a long period of time under a
blazing sun or in cold weather).• The vehicle tilts significantly.• The vehicle is driven on a rough road (with a
bumpy, gravel, hilly, or grassy surface).• The vehicle is too close to an obstacle.• The sensors or surroundings have been wiped by
hand, or stickers or accessories have been
attached.
●The corner sensor system may not properly detect
the following:
• Objects that are thin, such as wire nets or ropes.• Objects that absorb sound waves, such as snow.• Objects that are shaped with a sharp angle.• Objects with a smooth surface, such as glass.• Objects that are low, such as kerbstones.

NOTE●The buzzer may sound lower than the normal warning
sound when the corner sensor system is receiving ultra-
sonic noise from other sources, but this is not a malfunc-
tion. The buzzer will stop sounding and the system will
return to normal operation after the noise is no longer
received.To operate
E00615700204
To operate the system while the ignition switch is “ON”, move
the selector lever to the “R” (REVERSE) position on an A/T
vehicle, or move the gearshift lever into reverse on a M/T vehi-
cle. To stop the operation, push the SONAR switch.The SONAR OFF indication lamp will illuminate to indicate
that the system has stopped operating.
It will flash in case there is a malfunction in the system. For
details, refer to “SONAR OFF indication lamp” on page 4-57.
To return the system to the operating state, push the SONAR
switch again. When the system returns to the operating state,
the buzzer sounds once and the SONAR OFF indication lamp
turns off.
NOTE●The SONAR OFF indication lamp flashes once when the
ignition switch is turned “ON”.

The warning buzzer sounds when the system detects an obsta-
cle during operation.NOTE●After pushing the SONAR switch, corner sensor system
operation differs according to the detection area setting.
• Setting when towbar is not equipped
When the selector lever is moved to the “R”
(REVERSE) position, the corner sensor system will
operate even if corner sensor system operation was
stopped by pushing the SONAR switch.
• Setting when towbar is equipped
When corner sensor system operation was stopped by
pushing the SONAR switch, the corner sensor system
will not operate until the engine has been stopped even
if the selector lever is moved to the “R” (REVERSE)
position.
To resume corner sensor system operation, push the
SONAR switch or stop and restart the engine, and then
move the selector lever to the “R” (REVERSE) position.
Warning for obstaclesIf there is an obstacle behind the vehicle, a warning buzzer
sounds to indicate the distance between the vehicle and the
obstacle.

SONAR OFF indication lamp
E00615900033
In case there is a malfunction in the corner sensor system, the
SONAR OFF indication lamp will flash and the warning
buzzer will sound for approximately 5 seconds. Even after the
buzzer has stopped sounding, the indication lamp will continue
flashing until the system reverts to the normal state. We recom-
mend you to have your vehicle inspected.
Cargo loads
E00609900634
Cargo loads precautions
CAUTION
!●Do not load cargo or luggage higher than the top of
the seatback. Be sure that your cargo or luggage
cannot move once your vehicle is moving.
Having either the rear view blocked, or your cargo
being thrown inside the cabin if you suddenly have
to brake can cause a serious accident or injury.●Load heavy cargo or luggage in the front of the vehi-
cle. If the load in the back of the vehicle is too heavy,
steering may become unstable.

Never place anything on top of these sensors, since doing
so will prevent them from functioning properly.
