Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it briey until the lane
change is complete. The arrow will automatically ash
three times The lever returns to its original position
when it is released.
Rapid ashing of arrows when signaling for a turn
or lane change can be caused by a burned-out signal
bulb. Other drivers will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeFuses and Circuit Breakers on page 5-117
for more information.

{CAUTION:
FCA may not detect and warn soon enough
to stationary or slow-moving vehicles or other
objects ahead of you. You could crash into
an object ahead of you. Do not rely on FCA
when approaching stationary or slow-moving
vehicles or other objects.
Unnecessary Warnings
FCA may occasionally provide an unnecessary
warning to guard rails, signs, and other stationary
objects. This is normal operation, your vehicle
does not need service.
Other Messages
There are three messages that may appear on the
Driver Information Center (DIC). They are CLEAN
RADAR, RADAR CRUISE NOT READY and
SERVICE RADAR CRUISE. SeeDIC Warnings
and Messages on page 3-80.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean
the lens. See “Cleaning the System” underAdaptive

Windshield Wipers
The lever on the right side of the steering column
operates the windshield wipers.
7(Mist):Pull the lever down and release it for a
single wiping cycle. The lever will return to its original
position. For more cycles, hold the lever down
before releasing it.
9(Off):Put the lever in this position to turn off
the wipers.
&(Delay):Put the lever in this position to set a delay
between wipes. Turn the delay adjustment band to
set the length of the delay.
x(Delay Adjustment):Use this band to set the
length of the delay between wipes when using the delay
feature. The closer you move the band toward mist,
the longer the delay. The windshield wiper lever must
be in delay for this feature to work.
6(Low Speed):Put the lever in this position for
slow, steady wiping cycles.
1(High Speed):Put the lever in this position for
rapid wiping cycles.
If the windshield wipers are in use for about six seconds
while you are driving, the exterior lamps will come on
automatically if the exterior lamp control is in AUTO.
SeeWiper Activated Headlamps on page 3-37for more
information.
Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen to the windshield,
gently loosen or thaw them. If the blades do become
damaged, install new blades. For more information, see
Windshield Wiper Blade Replacement on page 5-55.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Your vehicle (STS-V only) is equipped with a feature
that disables the wiper system when the hood is
open and your vehicle is stopped. Opening the hood
will automatically park the wipers if they are not parked.
This prevents the wipers from interfering with hood
operation. Be sure the hood is not opened when you
require the vehicle’s wipers out of the park position,
such as when changing the wiper blades.

Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior side of the windshield behind
the rearview mirror. It is used to automatically operate
the wipers by monitoring the amount of moisture
build-up on the windshield. Wipes occur as needed to
clear the windshield depending on driving conditions
and the sensitivity setting. In light rain or snow,
fewer wipes will occur. In heavy rain or snow, wipes
will occur more frequently. The Rainsense™ wipers
operate in a delay mode as well as a continuous low
or high speed as needed. If the system is left on for long
periods of time, occasional wipes may occur without
any moisture on the windshield. This is normal and
indicates that the Rainsense™ system is activated.
To activate the Rainsense™ system, turn the wiper band
to delay mode and select one of the four sensitivity
levels indicated on the wiper stalk. The position closest
to off is the lowest sensitivity setting, level one. This
allows more rain or snow to collect on the windshield
between wipes. Turning the wiper band away from
you to higher sensitivity levels increases the sensitivity
of the system and frequency of wipes. The highest
sensitivity setting, level four, is closest to low.A single wipe will occur each time you turn the wiper
stalk to a higher sensitivity level to indicate that the
sensitivity level has been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The mist and wash cycles operate as normal and
are not affected by the Rainsense™ function. The
Rainsense™ system can be overridden at any time by
manually turning the wiper band to low or high speed.
When Rainsense™ is active, the headlamps will turn
on automatically. The headlamps will turn off again
once the wipers turn off if it is light enough outside.
If it is dark, they will remain on. SeeWiper Activated
Headlamps on page 3-37.
Notice:Do not place stickers or other items on
the exterior glass surface directly in front of
the moisture sensor. Doing this could cause the
moisture sensor to malfunction.

Windshield Washer
K(Washer Fluid):The lever on the right side of the
steering column also controls the windshield washer.
There is a button at the end of the lever. To spray
washer uid on the windshield, press the button and
hold it. The washer will spray until you release the
button. The wipers will continue to clear the window
for about six seconds after the button is released and
then stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
If the uid in the windshield washer uid reservoir is
low, the message CHECK WASHER FLUID will appear
on the Driver Information Center (DIC) display. It will
take 60 seconds after the bottle is relled for this
message to turn off. For information on the correct
washer uid mixture to use, seeWindshield Washer
Fluid on page 5-40andRecommended Fluids and
Lubricants on page 6-13.
Headlamp Washer
Your vehicle may have headlamp washers. The headlamp
washers clear debris from the headlamp lenses.
The headlamp washers are located to the inside of
the headlamps.
To wash the headlamps, press the washer button
located at the end of the windshield wiper lever.
Both the headlamps and the windshield will be washed.
After the rst wash, the headlamps will be washed
after the fth press of the windshield washer button.
3-16

The headlamps must be on to be washed. If the
headlamps are off, only the windshield will be washed
when the washer button is pressed. If the washer uid
is low, the headlamp washers will not work.
SeeWindshield Washer on page 3-16for additional
information.
Cruise Control
These controls are
located on the end
of the multifunction
lever.
9(Off):Move to this position to turn the system off.
R(On):Move to this position to turn on the system.
+ (Resume/Accelerate):Move to this position to make
the vehicle resume a previously set speed or to
accelerate when cruise is already active.
T(Set/Decrease):Press this button to set the speed
or to decrease the speed when cruise is already active.With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained 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 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 excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
If your vehicle is in cruise control when the Traction
Control System (TCS) begins to limit wheel spin or
the stability control system activates, the cruise control
automatically disengages. SeeTraction Control
System (TCS) on page 4-6andStabiliTrak
®System
on page 4-8orEnhanced StabiliTrak®on page 4-9.
When road conditions allow you to safely use it again,
you may turn the cruise control back on.
