adjacent lanes and advises the driver of the presence of such vehicles via the indi-
cators on the outside rear view mirrors.
Vehicles that are traveling in areas that are not visible using the outside rear
view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that are not visible
using the outside rear view mirrors (the blind spots)
■BSM function detection areas
The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 0.5 m (1.6 ft.) to 3.5 m (11.5 ft.) from either side of the vehicle*1

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching rap-idly from behind into a blind spot. Do not
overly rely on the BSM function. As the function cannot judge if it is safe to change lanes, over reliance could lead to
an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.

■ECB (Electronically Controlled
Brake System)
The electronically controlled system
generates braking force correspond-
ing to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the
brakes are applied suddenly, or if the
brakes are applied while driving on a
slippery road surface
■Brake assist
Generates an increased level of brak-
ing force after the brake pedal is
depressed when the system detects a
panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning on
slippery road surfaces
■Secondary Collision Brake (if
equipped)
When the airbag sensor detects a colli-
sion, the brakes and brake lights are
automatically controlled to reduce the
vehicle speed and that helps reduce
the possibility of further damage due to
a secondary collision.
■TRC (Traction Control)
Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads
■Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill
■VGRS (Variable Gear Ratio Steer-
ing) (if equipped)
Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement
■DRS (Dynamic Rear Steering) (if
equipped)
Contributes to the turning characteris-
tics and responsiveness of the vehicle
by slightly adjusting the rear wheel
angle of the vehicle in accordance with
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel
