Engaging ACC With the Set Button
{WARNING:
If you leave your Adaptive Cruise Control switch
on when you are not using cruise, you might hit a
button and go into cruise when you do not want
to. You could be startled and even lose control.
Keep the Adaptive Cruise Control switch off until
you want to use cruise control.
The set speed is selected by the driver. This is thespeed your vehicle will travel if there is no vehicledetected in its path.
To set ACC, do the following:
1. Press the]button.
2. Get up to the speed desired.
3. Press in the SET– button and release it.
4. Take your foot off the accelerator pedal.
Once ACC is set, it may immediately apply the brakes ifit detects a vehicle ahead is too close or movingslower than your vehicle.
The on symbol is located on the display at the top of theinstrument panel to the right of the driver. When the onsymbol is lit on the display, it indicates that ACC is active.
A message on the DIC will also display when ACC isset. SeeDIC Warnings and Messages on page 4-67.
Keep in mind speed limits, surrounding traffic speeds,and weather conditions when adjusting your set speed.
If the vehicle is in ACC when the traction controlsystem begins to limit wheel spin, the ACC willautomatically disengage. SeeTraction Control System(TCS) on page 5-6andStabiliTrak®System onpage 5-5. When road conditions allow you to safely useit again, the ACC can be turned back on.
Increasing Set Speed While Using ACC
There are two ways to increase the set speed:
•Use the accelerator to get to the higher speed.
Press the SET– button and then release thebutton and the accelerator pedal. The vehicle willnow cruise at the higher speed.
•Press the +RES button. Hold it there until the
desired set speed is displayed on the DriverInformation Center (DIC), then release the switch.To increase the set speed in very small amounts,move the switch briefly to +RES. Each timethis is done, the set speed increasesby 1 km/h (1 mph).

If this symbol does not appear, or disappears briefly,ACC will not respond to vehicles you may see ahead.
{WARNING:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Do not use Adaptive Cruise Control when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” later in
this section.
ACC automatically slows your vehicle down whenapproaching a slower moving vehicle. It then adjustsyour vehicle speed to follow the vehicle in front atthe selected follow distance. Your vehicle speedincreases or decreases to follow the vehicle in front ofyou, but will not exceed the set speed. It may applylimited braking, if necessary. When braking is active,your brake lights will come on. Braking may feelor sound different than if you were applying the brakesyourself. This is normal.
Stationary or Very Slow-Moving Objects
{WARNING:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not use Adaptive Cruise
Control when approaching stationary or
slow-moving vehicles or other objects.
{WARNING:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. Your vehicle may accelerate
toward objects, such as a stopped vehicle that
suddenly appears after the lead vehicle changes
lanes. Your complete attention is always required
while driving and you should be ready to take
action and apply the brakes.

Low-Speed Deactivation
If your vehicle speed falls below 32 km/h (20 mph) whilefollowing a vehicle ahead, ACC will begin to disengage.The Driver Alert symbol will flash and the warningbeep will sound. The driver must take action sinceACC will not slow the vehicle to a stop.
Passing a Vehicle/ACC Override
To increase speed to pass a vehicle, use the acceleratorpedal. While you are doing this, the system will notautomatically apply the brakes. A message will appearon the DIC. SeeDIC Warnings and Messages onpage 4-67. Once you remove your foot from theaccelerator pedal, ACC will return to normal operationand be able to apply the brakes, if needed.
{WARNING:
If you rest your foot on the accelerator pedal, the
system will not automatically apply the brakes.
You could crash into a vehicle ahead of you. Do
not rest your foot on the accelerator pedal when
using Adaptive Cruise Control.
Curves in the Road
{WARNING:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle in
your lane. You could crash into a vehicle ahead of
you, or lose control of your vehicle. Give extra
attention in curves and be ready to use the brakes
if necessary. Select an appropriate speed while
driving in curves.
ACC may operate differently in a sharp curve. It mayreduce your vehicle speed if the curve is too sharp.
4-22

When following a vehicle and entering a curve, ACCcould lose track of the vehicle in your lane andaccelerate your vehicle. When this happens the VehicleAhead symbol will not appear.
ACC may detect a vehicle that is not in your lane andapply the brakes.
ACC may, occasionally, provide a driver alert and/orbraking that you consider unnecessary. It could respondto signs, guardrails, and other stationary objectswhen entering or exiting a curve. This is normaloperation. Your vehicle does not need service.
4-23

Highway Exit Ramps
{WARNING:
Adaptive Cruise Control may lose track of the
vehicle ahead and accelerate up to your set speed
while entering or on highway exit ramps. You
could be startled by this acceleration and even
lose control of the vehicle. Disengage Adaptive
Cruise Control before entering a highway exit
ramp. Do not use Adaptive Cruise Control while
entering or on exit ramps.
Other Vehicle Lane Changes
If another vehicle enters the same lane as you, ACC willnot detect the vehicle until it is completely in the lane.Be ready to take action and apply the brakes yourself.
Using ACC on Hills and When Towing a
Trailer
How well ACC will work on hills and when towing atrailer depends on your vehicle’s speed, vehicle load,traffic conditions and the steepness of the hills. Itmay not detect a vehicle in your lane while driving onhills. When going up steep hills, you may want touse the accelerator pedal to maintain your vehicle’sspeed. When going downhill, especially when towing atrailer, you may want to brake to keep your speeddown. Applying the brake disengages the system. Youmay choose not to use ACC on steep hills, especiallywhen towing a trailer.
Disengaging ACC
To turn off the system, apply the brake pedal, press thecancel button, or press the ACC button.

Electric Power Management
The vehicle has Electric Power Management (EPM) thatestimates the battery’s temperature and state ofcharge. It then adjusts the voltage for best performanceand extended life of the battery.
When the battery’s state of charge is low, the voltage israised slightly to quickly bring the charge back up.When the state of charge is high, the voltage is loweredslightly to prevent overcharging. If the vehicle has avoltmeter gage or a voltage display on the DriverInformation Center (DIC), you may see the voltage moveup or down. This is normal. If there is a problem, analert will be displayed.
The battery can be discharged at idle if the electricalloads are very high. This is true for all vehicles. This isbecause the generator (alternator) may not bespinning fast enough at idle to produce all the powerthat is needed for very high electrical loads.
A high electrical load occurs when several of thefollowing are on, such as: headlamps, high beams, foglamps, rear window defogger, climate control fan athigh speed, heated seats, engine cooling fans, trailerloads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of thebattery. It does this by balancing the generator’s outputand the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, wheneverneeded. It can temporarily reduce the power demands ofsome accessories.
Normally, these actions occur in steps or levels, withoutbeing noticeable. In rare cases at the highest levelsof corrective action, this action may be noticeable to thedriver. If so, a Driver Information Center (DIC)message might be displayed, such as BATTERYSAVER ACTIVE, BATTERY VOLTAGE LOW, orLOW BATTERY. If this message is displayed, it isrecommended that the driver reduce the electrical loadsas much as possible. SeeDIC Warnings and Messageson page 4-67.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s batteryagainst drainage from the interior lamps, trunk lamp,glove box lamp, or the garage door opener. When theignition is turned off, the power to these features willautomatically turn off after 10 minutes. Power willbe restored for an additional 10 minutes if any door ortrunk is opened, or the courtesy lamp switch isturned on.
