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
Cruise Control on page 3-20.
Flash-to-Pass
This feature allows you to use the high-beam
headlamps to signal the driver in front of you that
you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When this is done the following
will occur:
If the headlamps are off, in low-beam or in
Daytime Running Lamps (DRL) mode, the
high-beam headlamps will turn on. They will
stay on as long as the lever is held there.
Release the lever to turn them off.
If the headlamps are in high-beam mode, they will
switch to low beam. To return to high-beam, push the
lever forward.
Windshield Wipers
The windshield wiper lever is located on the right side of
the steering column.
Move the lever to one of the following positions:
7(Mist):Move to mist for a single wiping cycle
and then release it. The lever will return to its original
position. Hold the lever in this position for continuous
wiping cycles.
9(Off):Turns off the wipers.
&(Delay):For a delayed wiping cycle. Turn the delay
adjustment band to set the length of the delay.
3-13

x(Delay Adjustment):Use this band to set the
length of the delay between wipes when using the delay
feature. The closer the band is moved toward mist,
the longer the delay. The windshield wiper lever must
be in delay for this feature to work.
6(Low Speed):For slow, steady wiping cycles.
1(High Speed):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 3-36for
more information.
Clear snow and ice from the wiper blades before using
them. If the blades are frozen to the windshield, loosen or
thaw them. If they become damaged, install new blades.
For more information, seeWindshield Wiper Blade
Replacement on page 5-52.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
For STS-V, the vehicle is equipped with a feature
that disables the wiper system when the hood is open
and the vehicle is stopped. Opening the hood will
automatically park the wipers if they are not parked.
Rainsense™ II Wipers
For vehicles with 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 occurs each
time the wiper stalk is turned to a higher sensitivity level
to indicate that the sensitivity level has been increased.
3-14

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 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 3-36.
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
The windshield washer button is located at the end
of the windshield wiper lever on the right side of
the steering column.
K(Washer Fluid):Press and hold to spray
windshield washer uid on the windshield. The washer
will spray until the button is released. The wipers will
continue to clear the window for about six seconds after
the button is released and then stop or return to the
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 5-38andRecommended Fluids and
Lubricants on page 6-13.

rst wash, the headlamps will be washed after the
fth press of the windshield washer button.
The headlamps must be on to be washed. If the washer
uid is low, the headlamp washers will not work.
SeeWindshield Washer on page 3-15for additional
information.
Cruise Control
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
If the brakes are applied, the cruise control shuts off.
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
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 the 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 4-10andStabiliTrak
®System on page 4-6
orEnhanced StabiliTrak®on page 4-6. When road
conditions allow you to safely use it again, the cruise
control can be turned back on.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with IntelliBeam, read this entire section
before using this feature.
IntelliBeam is an enhancement to the vehicle’s
headlamp system. It uses a light sensor located on
the back of the rearview mirror to turn the high-beam
headlamps on and off depending on approaching traffic.
The IntelliBeam system turns the high-beam headlamps
on when it is dark enough, there is no other traffic
present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam
AUTO3(IntelliBeam On/Off):Press and release
the IntelliBeam button on the inside rear view mirror.
The indicator on the mirror turns on. Once the system
has been turned on, it remains on each time the vehicle
is started. Additionally, the IntelliBeam system must be
enabled.
To enable the System, turn the exterior lamp control
to AUTO, with the turn signal/multifunction lever in its
starting position. The High-Beam On Light appears on
the instrument panel cluster when the high-beams are on.
SeeHighbeam On Light on page 3-70. The vehicle has
variable intensity high-beams. The high-beam indicator
on the instrument panel cluster comes on as soon as the
high-beams start to come on, and remains on until the
high-beams have completely turned off. Vehicles with
IntelliBeam quickly turn off the high-beams if the system
detects the sudden presence of vehicle lights ahead.
3-33

Driving with IntelliBeam
IntelliBeam only activates the high-beams when driving
over 20 mph (32 km/h).
The high-beam headlamps remain on, under the control
of IntelliBeam, until any of the following situations occur:
The system detects an approaching vehicle’s
headlamps.
The system detects a preceding vehicle’s taillamps.
The outside light is bright enough that high-beam
headlamps are not required.
The high-beam headlamps are manually turned on
or you use the ash-to-pass feature. SeeHeadlamp
High/Low-Beam Changer on page 3-9and
Flash-to-Pass on page 3-13.
When either of these conditions occur, the IntelliBeam
feature is temporarily disabled until the high-beam
stalk is returned to its starting position. If either of
these conditions occur and IntelliBeam already has
the high-beam headlamps on, the feature is disabled
and the light in the mirror turns off.
The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam is disabled until the
control is turned back to the AUTO position and the
AUTOMATIC LIGHTS ON message displays on
the DIC.
The IntelliBeam system is turned off at the inside
rearview mirror.
The vehicle’s speed drops below 15 mph (24 km/h).
IntelliBeam may not turn off the high-beams if the
system cannot detect other vehicle’s lamps because
of any of the following:
The others vehicle’s lamp(s) are missing, damaged,
obstructed from view, or otherwise undetected.
The other vehicle’s lamp(s) are covered with dirt,
snow and/or road spray.
The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist, or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view of
the IntelliBeam light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze, or other obstructions.
Your vehicle is loaded such that the front end of
the vehicle points upward, causing the IntelliBeam
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
