• While the electronic parking brake is ap-plied or released, an operating sound is
heard from the lower side of the rear seat.
This is normal and does not indicate a
malfunction.
•
When the electronic parking brake is fre-
quently applied and released in a short pe-
riod of time, the parking brake may not op-
erate in order to prevent the parking brake
system from overheating. If this occurs, op-
erate the electronic parking brake switch

tronic parking brake indicator light (red) in
the meter and in the parking brake switch
turns off when the parking brake is released.
• When pulling the electronic parking brake switch up with the ignition switch in the
OFF or AUTO ACC position, the parking
brake switch indicator light will continue
to illuminate for a short period of time. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of the auto-

SYSTEM MAINTENANCE
The TSR system uses the same multi-sensing
front camera unit that is used by the Lane
Departure Warning (LDW) system, located in
front of the interior rearview mirror. For ad-
ditional information, see ”System mainte-
nance” (P. 5-38).
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDW system
could result in serious injury or death.
• This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It is
the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the trav-
eling lane, and be in control of the vehicle
at all times. The LDW system will operate when the ve-
hicle is driven at speeds of approximately 37
mph (60 km/h) and above, and only when the
lane markings are clearly visible on the road.
The LDW system monitors the lane markers
on the traveling lane using the camera unit
O1
located above the inside mirror.
The LDW system warns the driver with an
indicator in the vehicle information display
and the steering wheel will vibrate, indicating
that the vehicle is beginning to leave the driv-
ing lane. For additional information, see
“LDW system operation” (P. 5-35).
