Saturn 2009 Aura Hybrid Automobile User Manual


 
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” the vehicle to attempt to
free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions
where high wheel spin is required. See If Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-21.
ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light will be
on solid to warn the driver that ESC is disabled and
requires service. If the problem does not clear after
restarting the vehicle, see your dealer/retailer for service.
See DIC Warnings and Messages on page 3-44 for
more information.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. See Accessories and
Modifications on page 5-3 for more information.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the front wheels are spinning too much or are
beginning to lose traction. When this happens,
the system works the front brakes and reduces engine
power by closing the throttle and managing engine
spark to limit wheel spin.
This light will flash when
the traction control system
is limiting wheel spin.
The system may be heard or felt while it is working, but
this is normal.
