Windshield Washer
L (Washer Fluid): There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer fluid on the windshield, push
the paddle. The wipers will clear the window and then
either stop or return to your preset speed.
{ CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.
Rear Window Wiper/Washer
This knob is located on the
instrument panel below the
climate controls.
Z
(Rear Wiper): To turn the rear wiper on, turn the
knob to either 1 or 2. For a slower wiping speed, turn the
knob to 1. For a faster wiping speed, turn the knob to 2
0 (Off): To turn the wiper off, turn the knob to this
symbol.
= (Washer Fluid): To wash and wipe the window,
press the button within the knob with this symbol.
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
windows, check the fluid level.
