warning light MAZDA MODEL 3 HATCHBACK 2012 (in English) Repair Manual

Black plate (200,1)
lThe detectability of the radar sensors has its limitations. The BSM system may not operate
properly under the following conditions:
lIce, snow, or soil adheres to the rear bumper surface around the radar sensors.lDuring adverse weather conditions such as rain or snow, or under conditions where water is
sprayed.
lThe rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
lThe radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
lMotorcycleslVehicles with body shapes that radar may not reflect such as a flatbed trailer with no cargo.lVehicles with lower body height such as sports cars.lHave the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied to the
rear bumper, even in a minor accident. If the vehicle is driven with a damaged radar sensor, the
system may not operate properly resulting in an accident.
lFor repairs or paintwork around the radar sensors, or replacement of the bumper, consult an
Authorized Mazda Dealer.
lThe radar sensors of the BSM system may be regulated under the radio wave related laws of the
country where the vehicle is driven. The sensors in this system are approved for use in the U.S.A.
(including territories), Canada, and Mexico. If a vehicle with a BSM system is driven in a country
other than the U.S.A., Canada, or Mexico, the system has to be turned off using the BSM OFF
switch.
lThe detection area of the system has been determined based on the lane width of general
freeways. Therefore on a road with a narrower lane width, the system may detect vehicles on a
lane next to the adjacent lane and operate the warning light/beep. On a road with wider lane
width, the system may not detect vehicles on the adjacent lane and may not operate the warning
light/beep.
lOperation of the warning light/beep may be delayed or the system may not operate the warning
light/beep under the following conditions:
lThe vehicle accelerates from a standing-start with a vehicle alongside.lA vehicle moves from a lane two lanes over to the adjacent lane.lThe difference in vehicle speed between your vehicle and another vehicle is larger when
passing or being passed, and the vehicle passes the detection area within a short period of
time.
lOn a steep incline, or when there is a difference in height between lanes.lImmediately after the system has been activated by pressing the BSM OFF switch again after it
has been turned off (BSM OFF indicator light in instrument panel illuminates) by pressing the
switch.
lAlthough the system may detect objects on the road side such as parked vehicles or guardrails and
operate the warning light/beep, it does not indicate a malfunction.
lIf the vehicle is driven on a road with less traffic and few vehicles that the radar sensors can
detect, the system may pause (The BSM OFF indicator light in the instrument panel flashes).
However, it does not indicate a malfunction.

qBrake System Warning Light
This warning has the following functions:
Parking brake warning
The light illuminates when the parking
brake is applied with the ignition switched
to START or ON. It turns off when the
parking brake is fully released.
Low brake fluid level warning
If the light stays on after the parking brake
is fully released, you may have a brake
problem.
Drive to the side of the road and park off
the right-of-way. You may notice that the pedal is harder to
depress or that it may go closer to the
floor. In either case, it will take longer to
stop the vehicle.
1. With the engine stopped, open the
hood and check the brake fluid level
immediately, and then add fluid if
required (page 8-24).
2. After adding fluid, check the light again.
If the warning light remains on, or if the
brakes do not operate properly, do not
drive the vehicle. Have it towed to an
Authorized Mazda Dealer.
Even if the light turns off, have your
brake system inspected as soon as
possible by an Authorized Mazda Dealer.
NOTE
Having to add brake fluid is sometimes an
indicator of leakage. Consult an Authorized
Mazda Dealer as soon as possible even if the
brake light is no longer illuminated.
