Vehicle recognition
OTM058128
Some vehicles in your lane cannot be
recognized by the sensor: - Narrow vehicles such as motorcycles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles (When the vehicle ahead drives away, the system may not
detect a stopped vehicle.)
- Vehicles with small rear profile such as trailers with no loads
A vehicle ahead cannot be recognized
correctly by the sensor if any of following
occurs: - When the vehicle is pointing upwards due to overloading in the luggage
compartment.
- While the steering wheel is operating.
- When driving to one side of the lane.
- When driving on narrow lanes or on curves.
- Apply the brake or accelerator pedal if necessary.
WARNING
When using the Smart Recuperation
System take the following precautions: • If an emergency stop is necessary,
you must apply the brakes.
• Keep a safe distance according to
road conditions and vehicle speed. If
the vehicle to vehicle distance is too close during a high-speed driving, a
serious collision may result.
• Always maintain sufficient braking
distance and decelerate your vehicle
by applying the brakes if necessary.
• The Smart Recuperation System
cannot recognize a stopped vehicle,
pedestrians or an oncoming vehicle.
Always look ahead cautiously to
prevent unexpected and sudden
situations from occurring.
• Vehicles moving in front of you with
a frequent lane changes may cause
a delay in the system's reaction or
may cause the system to react to a
vehicle actually in an adjacent lane.
Always drive cautiously to prevent
unexpected and sudden situations
from occurring.
• The Smart Recuperation System
may not recognize complex driving
situations so always pay attention to
driving conditions and control your
vehicle speed.
NOTICE
The Smart Recuperation System may
not operate temporarily due to: • Electrical interference
• Modifying the suspension
• Differences of tire abrasion or tire
pressure
• Installing different type of tires
