Cruise Control
{
WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
When the brakes are applied, the
cruise control turns off.
If your vehicle has the StabiliTrak
®
system and begins to limit wheel
spin while you are using cruise
control, the cruise control will
automatically disengage. See
StabiliTrak
®
System on page 9 ‑ 52 .
When road conditions allow the
cruise control to be safely used
again, it can be turned back on.
The cruise control buttons are
located on the left side of the
steering wheel.

Setting Cruise Control
If the cruise button is on when not in

cruise when not desired. Keep the

is not being used.
