United States
When the system is on and the parking brake is fully
released, this warning light will come on to let you know
if there is a problem.
See Enhanced Traction System Warning Light on
page 3-28. 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 Enhanced
Traction System on. But you can turn the system off if
you prefer.
Canada
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on. If
the Enhanced Traction System is limiting wheel spin
when you press the button to turn the system off,
the warning light will come on — but the system will not
turn off right away. It will wait until there is no longer
a current need to limit wheel spin.
You can turn the system back on at any time by
pressing the button again. The Enhanced Traction
System warning light should go off.
To turn the system on or
off, press the top of the
ETS button on the left side
of the instrument panel
near the instrument panel
brightness control.
