Limited-Slip Differential - Chevrolet 2011 HHR Owner's 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
L (Low), the vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check the 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 the 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 4 41 for
more information on the messages associated with this
light.
To limit wheel spin, especially in slippery road
conditions, ETS should always be left on. But the
system can be turned off if needed.
To turn the system off, shift to L (Low) or R (Reverse).
When the system is turned off, the ETS indicator/
warning light will come on and stay on and the
TRACTION OFF message will be displayed when the
gear shift is in L (Low). The indicator/warning light and
5-12
message will not come on when the gear shift is in
R (Reverse). If the ETS is limiting wheel spin when
the transmission is shifted to L (Low) or R (Reverse)
to turn the system off, the indicator/warning light and
TRACTION OFF will come on in L (Low). But the
system will not turn off right away. It will wait until there
is no longer a current need to limit wheel spin. See DIC
Warnings and Messages on page 4 41 for more
information on the messages associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non dealer/non retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications on page 6 3 for more information.

Limited-Slip Differential

Vehicles with a limited-slip differential can give more
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when traction is
low, this feature allows the drive wheel with the most
traction to move the vehicle. The limited slip design
has minimal impact to the steering feel, but boosts the
traction performance under all conditions.
