To wash the window, press the wash button located on
the control. The control must be in either LO or HI.
The rear window washer uses the same fluid bottle as
the windshield washer. However, the rear window
washer will run out of fluid before the windshield washer.
If you can wash your windshield but not your rear
window, check your fluid level.
Cruise Control (If Equipped)
With cruise control, you
can maintain a speed of
about 25 mph (40 km/h) or
more without keeping
your foot on the
accelerator. This can really
help on long trips. Cruise
control does not work
at speeds below about
25 mph (40 km/h).
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will shut off.
Cruise control can be danL 'ous where
you can't drive safely at a steady speed.
So, don't use your 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
needless wheel spinning, and you could
lose control. Don't use cruise control on
slippery roads.
If you have an automatic transmission and you apply
your brakes, the cruise control will shut off.
