The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle 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 2-22
.
This warning light appears
on the instrument panel to
indicate that the ETS is
not on.
This symbol, along with
the message TRACTION
CONTROL OFF will
also display on the DIC for
three seconds when the
ETS is not active.
See
Enhanced Traction System Warning Light on
page 3-38
. When this warning 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 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. See “Rocking
Your Vehicle To Get It Out” under
In Sand, Mud, Ice or Snow on page 4-32
.
To turn the system off,
press the traction control
button located on the
console.
If the system is limiting wheel spin when you press the
button the system will turn off instantly. You can
turn the system back on at any time by pressing the
button again.
