Windshield Washer
At the top of the multifunction lever, there's a paddle
with the word PUSH on it. To spray washer fluid on the
windshield, push the paddle. The wipers will run for
several sweeps and then either stop or return to your
preset speed.
~
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.

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).
When you apply your brakes, the cruise control
shuts off.
