Remember: Anti-lock doesn't 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 won't 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
Don't pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You may feel the system
working, or you may notice some noise, but this is normal.
Enhanced Traction System (If Equipped)
If your vehicle has the optional four-speed automatic
transaxle, it also has an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful
in slippery road conditions. The system operates only
when the transaxle shift lever is in the REVERSE (R),
THIRD (3) or OVERDRIVE
(a)
position and the
system senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may also
upshift the transaxle to limit wheel spin.
LOW
TRAC
This light will come
on
when your Enhanced
Traction System is limiting
wheel spin. See "Enhanced
Traction System Active
Light" in the Index.
You may feel or hear the system working, but this
is normal.
ETS
OFF
When the transaxle shift
lever is in any position
other than FIRST (1) or
SECOND ( 2 ) and the
parking brake is fully
released, this warning light
will come on to let you
know if there's a problem
with the system.
