Remember: Anti-lock does not change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you will not have time to apply your brakes if
that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.

Using Anti-Lock

Do not pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this is
normal.

Braking in Emergencies

With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.

Traction Assist System (TAS)

If your vehicle has two-wheel drive, it has a Traction
Assist System (TAS) that limits wheel spin. This
is especially useful in slippery road conditions. The
system operates only if it senses that one or both of the
rear wheels are spinning or beginning to lose traction.
When this happens, the system reduces engine
power to limit wheel spin.

The low traction symbol next to the button will come on
when the TAS is limiting wheel spin. You may feel or
hear the system working, but this is normal.

The Traction Assist System may operate on dry roads
under some conditions. When this happens, you may
notice a reduction in acceleration. This is normal and
doesn’t mean there’s a problem with your vehicle.
Examples of these conditions include a hard acceleration
in a turn, an abrupt upshift or downshift of the
transmission or driving on rough roads.

If your vehicle is in cruise control when the TAS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely use
it again, you may re-engage the cruise control. See
Cruise Control on page 3-11. When the traction control
off symbol on the button is on, the TAS is off and will not
limit wheel spin. Adjust your driving accordingly.

The traction control off symbol on the button will come
on under the following conditions:

The Traction Assist System is turned off, either by
pressing the TAS on/off button or by turning off
the automatic engagement feature of the TAS.

The transmission is in FIRST (1) gear; TAS will not
operate in this gear. This is normal.
