2-33Windshield Washer (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, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision. Rear Window Washer/Wiper
This knob is located on
the instrument panel.
To turn the rear wiper on, turn the knob to either 1 or 2.
For long delayed wiping, turn the knob to 1. For short
delayed wiping, turn the knob to 2.
(Off): To turn the wiper off, turn the knob to
this symbol.
(Washer Fluid): To wash the window, press 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.
For more information, see ªLow Washer Fluidº in the Index.

2-35Setting Cruise Control
CAUTION:If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal. United States Canada
The CRUISE light on the instrument panel will
illuminate when the cruise control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed and
then you apply the brake. This, of course, disengages the
cruise control. But you don't need to reset it.
Once you're going about 25 mph (40 km/h) or more,
you can move the cruise control switch from ON to
R/A (Resume/Accelerate) briefly.
You'll go right back up to your chosen speed and
stay there.
If you continue to hold the switch at R/A, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don't
hold the switch at R/A.

Warning Lights, Gages
and Indicators This part describes the warning lights and gages on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is

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.
