qTCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light flashes.
If the light stays on, the TCS or DSC may
have a malfunction and they may not
operate correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
lIn addition to the indicator light flashing, a
slight lugging sound will come from the
engine. This indicates that the TCS is
operating properly.
lOn slippery surfaces, such as fresh snow, it
will be impossible to achieve high rpm
when the TCS is on.
Dynamic Stability Control
(DSC)
í
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.
Refer to ABS (page 5-8) and TCS (page
5-26).
DSC operation is possible at speeds
greater than 20 km/h (12 mph).
WARNING
Do not rely on the dynamic stability
control as a substitute for safe driving:
The dynamic stability control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road
contact because of water on the road
surface). You can still have an
accident.

NOTElWhen DSC is on and you attempt to free the
vehicle when it is stuck, or drive it out of
freshly fallen snow, the TCS (part of the
DSC system) will activate. Depressing the
accelerator will not increase engine power
and freeing the vehicle may be difficult.
When this happens, turn off the TCS/DSC.
lIf the TCS/DSC is off when the engine is
turned off, it automatically activates when
the ignition is switched on.
lLeaving the TCS/DSC on will provide the
best stability.

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 8-23). 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.
WARNING
Do not drive with the brake system
warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible: Driving with the brake system
warning light illuminated is
dangerous. It indicates that your
brakes may not work at all or that
they could completely fail at any
time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.

qABS Warning Light
The warning light stays on for a few
seconds when the ignition is switched
ON.
If the ABS warning light stays on while
you're driving, the ABS control unit has
detected a system malfunction. If this
occurs, your brakes will function normally
as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.
NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
l(With DSC vehicles)
The brake assist system does not operate
while the ABS warning light is illuminated.
qElectronic Brake Force
Distribution System Warning
If the electronic brake force distribution
control unit determines that some
components are operating incorrectly, the
control unit may illuminate the brake
system warning light and the ABS
warning light on simultaneously. The
problem is likely to be the electronic
brake force distribution system.
WARNING
Do not drive with both the ABS warning
light and brake warning light
illuminated. Have the vehicle towed to
an Authorized Mazda Dealer to have
the brakes inspected as soon as
possible:
Driving when the brake system
warning light and ABS warning light
are illuminated simultaneously is
dangerous.
When both lights are illuminated, the
rear wheels could lock more quickly
in an emergency stop than under
normal circumstances.
