The cruise control will turn off when any of the
following occur:
The brakes are applied,
the clutch is applied (manual transaxle),
the parking brake is applied, or
the brake system warning light is on.
Cruise control can be dangerous where
you can’t drive safely at a steady speed.
So, don’t use your cruise control on
winding roads or
in heavy traffic.

slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Don’t use cruise control on
slippery roads.

traction system,
if your vehicle has this feature, begins to
limit wheel spin, the cruise control will automatically
disengx~e. See Enhanced Trac?im Sys?m (ETSI ar?
page 4-9. When road conditions allow you to safely use
it again, you may turn the cruise control back on.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will help
you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions.
As you will
see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working.
If you are
familiar with this section, you should not be alarmed
when this happens. Gages can
indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together
to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving,
or when one of the gages
shows there may be a problem, check the section that
tells you what to do about
it. Please follow this
manual’s advice. Waiting to do repairs can be
costly
- and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
