Noise from under vehicle after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound coming
from under the vehicle for several minutes. This is the sound of a fuel evaporation
leakage check and, it does not indicate a malfunction.

CAUTION
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any positions other than “P” or “N” the vehicle may accelerate
suddenly and unexpectedly, and may cause an accident.
●Do not leave the vehicle with the engine on for a long time. 
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do not enter the vehicle interior.
●In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the engine is running, and apply the parking
brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine. Running the engine at high speed while the
vehicle is stopped may cause the exhaust system to overheat, which could result
in a fire if combustible material is nearby.

In the vehicle-to-vehicle distance control mode, the set speed will be
increased or decreased as follows:
When the set speed is shown in “MPH”
Fine adjustment: By approximately 5 mph (8 km/h) each time the lever is
operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75 sec-
onds the lever is held
When the set speed is shown in “km/h”
Fine adjustment: By approximately 3.1 mph (5 km/h) each time the lever is
operated
Large adjustment: By approximately 3.1 mph (5 km/h) for each 0.75 sec-
onds the lever is held

Steering guide symbol
Displays the steering maneuvers required to avoid an obstacle. Move the
steering wheel in the direction shown by the arrow.
The steering guide symbol only
shows the maneuvers necessary to
avoid an obstacle.
When using the system, always
check your surroundings for
safety.
Beeps and obstacle distance
A beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves closer to the obstacle, the interval of
the beep becomes shorter.
●When the following obstacle distances are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than
1.1 ft. (35 cm).
●If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obstacles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.

●If multiple obstacles are detected in front and behind the vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of the vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn-
ing beeps will sound 2 beeps then one continuous beep.
●You can change the volume of the warning beeps. (P. 2 4 5 )
Obstacle detection range
About 10.0 ft. (300 cm)
About 3.0 ft. (100 cm)
About 5.0 ft. (150 cm)
About 1.5 ft. (50 cm)
The detection area of the sensors is
shown to the left.
If obstacles move too close to the
sensors, they will not be detected.
If the malfunction screen is dis-
played, the dual sensor detection
range will be shortened from 3.0 ft.
(100 cm) to 1.5 ft. (50 cm).
