Brakes
Antilock Brake System (ABS)
Wheels may be locked and slip during
sudden braking or braking on a slippery
road surface such as a snowy road. ABS is a
device to prevent the wheels from locking
by detecting a slippery condition during
braking and securing the directional stability
and handling stability of the vehicle. ABS
only assists in limited road conditions and
will not prevent a crash if you exceed safe
driving speeds for road conditions. Always
drive safely.
{
Warning
The braking distance on slippery road
surfaces is longer than that on a normal
dry paved road even with an
ABS-equipped vehicle. The braking
distance can become even slightly longer

Warning (Continued)
in deep snow and on a gravel road when
the ABS is operating than when it is not.
Therefore, always be aware of the road
and tire conditions (tire type and wear
condition), observe safe driving habits,
and drive while keeping a safe following
distance.
ABS does not prevent accidents if you do
not drive safely with current road
conditions in mind. Drive the vehicle at a
safe speed.
