Tra c t i o n C o n t r o l Sy s te m(TCS)
▼Traction Control System (TCS)
The Traction Control System (TCS)
enhances traction and safety by
controlling engine torque and braking.
When the TCS detects driving wheel
slippage, it lowers engine torque and
operates the brakes to prevent loss of
traction.

This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.

The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC Indication/
Indicator Light (Turns on) on page
7-27.
WARNING
Do not rely on the Traction Control
System (TCS) as a substitute for safe
driving:
The Traction Control System (TCS)
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.
Use snow tires or tire chains and drive
at reduced speeds when roads are
covered with ice and/or snow:
Driving without proper traction devices
on snow and/or ice-covered roads is
dangerous. The Traction Control
System (TCS) alone cannot provide
adequate traction and you could still
have an accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-77).
▼
TCS/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, DSC or
the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
In addition to the indicator light flashing , a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating
properly.
On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.
