Pontiac 2008 grand prix Automobile User Manual


 
If the vehicle is in cruise control when the traction
control system 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 3-12.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modifications
on page 5-3 for more information.
Enhanced Traction System (ETS)
If the vehicle has the 3.8L V6 engine and Antilock
brakes, it has 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.
This symbol comes on
the Driver Information
Center (DIC) when
the ETS 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 3-12.
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 2-28.
