For delay wiping, slide the switch up to the center
position next to the word DELAY on the rear wiper
control. The wiper will cycle every nine seconds.
To wash the window, push in on the switch. Window
washer fluid will continue to spray until the switch
is released. The wiper will continue with three more
wipes and then return to the setting that was chosen
before the lever was pushed.
Move the switch to OFF to turn off the rear window
washer.
The rear window washer uses the same fluid bottle as
the front windshield washer. If the fluid level is low in the
washer bottle, you may not be able to wash your rear
window. If you can wash your windshield, but not
your rear window, check the fluid level.
Cruise Control
Your vehicle may have this feature. 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).
When you apply your brakes, the cruise control shuts off.
{
CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not 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. Do not use cruise
control on slippery roads.
