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 transaxle to limit wheel spin.
The LOW TRAC message will be displayed when
your ETS is engaged and limiting wheel spin.
SeeLow Traction Message on page 182. You may
feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the ETS
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. SeeCruise Control
on page 147.
The ETS operates in all transaxle shift lever
positions. But the system can upshift the transaxle
only as high as the shift lever position you have
chosen, so you should use the lower gears
only when necessary.The ETS automatically comes on whenever you
start your vehicle. The light on the traction control
button will also come on to let you know the
system is on. To limit wheel spin, especially in
slippery road conditions, you should always leave
the system on. But you can turn the traction
control system off if you ever need to. You should
turn the system off if your vehicle ever gets
stuck in sand, mud or snow and rocking the
vehicle is required. SeeRocking Your Vehicle to
Get It Out on page 250andIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 249.
To turn the system on
or off, press the
enhanced traction
system button located
on the instrument panel.
