Chevrolet 2008 Cobalt Automobile User Manual


 
If the ETS indicator/warning light comes on and stays
on for an extended period of time when the transmission
shift lever is in any position other than LOW (L), your
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check your DIC messaging to determine whether it is
because of the driver turning off the system, or that the
system may not be working properly and your vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message
will be displayed.
See DIC Warnings and Messages on page 3-43 for
more information on the messages associated with
this light.
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.
To turn the system off, shift to LOW (L) or
REVERSE (R).
When you turn the system off, the ETS indicator/warning
light will come on and stay on and TRACTION OFF
message will be displayed when the gear shift is
in LOW (L). The indicator/warning light and message
will not come on when the gear shift is in REVERSE (R).
If the ETS is limiting wheel spin when you shift to
LOW (L) or REVERSE (R) to turn the system off, the
indicator/warning light and TRACTION OFF will come
on in LOW (L). But the system won’t turn off right away.
It will wait until there’s no longer a current need to
limit wheel spin.
See DIC Warnings and Messages on page 3-43 for
more information on the messages associated with
this light.
You can turn the system back on at any time by
shifting to AUTOMATIC OVERDRIVE (D) or
INTERMEDIATE (I). The ETS indicator/warning light
should go off.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. See Accessories and
Modifications on page 5-3 for more information.
Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most
driving conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
