Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. See Accessories and
Modifications on page 5-3 for more information.
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 TRACTION CONTROL ACTIVE message on
the Driver Information Center (DIC) will be displayed
when the system is limiting wheel spin.
If the vehicle is in cruise control when ETS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow safe use of it,
the cruise control can be used again. See Cruise
Control on page 3-10.
The ETS operates in all transmission shift lever
positions. But the system can upshift the transmission
only as high as the chosen shift lever position, so
use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-27.
This warning light, along
with the TRACTION
CONTROL OFF message,
will display on the DIC
for three seconds when
the ETS is not on.
If there is a problem with the system, the SERVICE
TRACTION SYSTEM message will also come on in
the DIC. 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. The ETS
should be turned off if the vehicle ever gets stuck in
sand, mud or snow and rocking the vehicle is required
To turn the ETS on or off, press the Traction Control
button located above the radio.
When the ETS is turned off, the ETS warning light will
come on along with the TRACTION CONTROL OFF
message on the DIC. It will disappear when the ETS is
turned back on. If the ETS is limiting wheel spin when the
traction control button is pressed, the ETS warning light
will come on and the ETS will turn off right away.
