Instrumentation and Controls
With cruise control, you can main-
tain a speed of about 40 km/h (25
mph) or more without keeping
your foot on the accelerator pedal.
Cruise control will not work if the
park brake is set or if the master
cylinder brake fluid level is low.
If your vehicle is in cruise control
when the traction control system
begins to limit wheel spin, the
cruise control will automatically
disengage.
See the following for more
information:
• Traction Control System
Once conditions are back to
normal, you may turn the cruise
control back on.
