Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) 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 front wheels are spinning or
beginning to lose traction. When this happens, the
system reduces engine power and may also
upshift the transmission to limit wheel spin. You
may feel or hear the system working, but this
is normal. The LOW TRACTION message
will appear on the Driver Information Center (DIC)
when the traction control system is limiting
wheel spin.
If your vehicle is in cruise control when the
enhanced traction system 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 167.
The Enhanced Traction System operates in all
transmission shift lever positions except PARK (P),
NEUTRAL (N) or REVERSE (R). But the system
can upshift the transmission only as high as
the shift lever position you’ve chosen, so you
should use the lower gears only when necessary.
See Automatic Transaxle Operation on page 122.
This light is located on
the instrument panel
cluster.
When the system is on, this light will come on and
stay on to let you know if there’s a problem, or
if the system has been turned off. When this light
is on, the system will not limit wheel spin.
Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the ETS on.
But you can turn the system off if you prefer.
