Parking Brake
The parking brake pedal islocated to the left of theregular brake pedal,near the driver door.
To set the parking brake, hold the regular brake pedaldown, then push the parking brake pedal down.
If the ignition is on, the brake system warning light onthe instrument panel cluster should come on. If itdoes not, you need to have the vehicle serviced.
A warning chime will sound if the parking brake is set,the ignition is on, and the vehicle speed is greaterthan 5 mph (8 km/h). The brake light will come on andstay on until the parking brake is released. SeeBrake System Warning Light on page 4-52for moreinformation.
To release the parking brake, hold the regular brakepedal down, then push the parking brake pedal down.When you lift your foot off the parking brake pedal,the pedal will follow your foot to the released position.
Notice:Driving with the parking brake on canoverheat the brake system and cause prematurewear or damage to brake system parts. Make surethat the parking brake is fully released and the brakewarning light is off before driving.
If you are towing a trailer and are parking on any hill,seeTowing a Trailer on page 5-26.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporarycondition, the message PARK ASSIST OFF will bedisplayed on the DIC and a red light will be shown onthe rear URPA display when the shift lever is moved intoR (Reverse). This occurs under the following conditions:
•The driver disables the system.
•The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,ice and slush. For cleaning instructions, seeWashing Your Vehicle on page 6-95.
•A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during thelast drive cycle, the red light may illuminate inthe rear display. Once the attached object isremoved, URPA will return to normal operation.
•A tow bar is attached to the vehicle.
•The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
•Other conditions may affect system performance,
such as vibrations from a jackhammer or thecompression of air brakes on a very large truck.
If the system is still disabled after driving forward atleast 25 km/h (15 mph), take the vehicle to yourdealer/retailer.
Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA)system. Read this entire section before using the system.
{WARNING:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
•Vehicles outside the side blind zones which
may be rapidly approaching.
•Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanesmay result in damage to the vehicle, injury, ordeath. Always check the outside and rearviewmirrors, glance over your shoulder, and use theturn signal before changing lanes.
When the system detects a vehicle in the side blindzone, amber SBZA displays will light up in the sidemirrors. This indicates that it may be unsafe to changelanes. Before making a lane change, always checkthe SBZA display, check the outside and rearviewmirrors, look over your shoulder for vehicles andhazards, and use the turn signal.
3-43

SBZA Detection Zones
The SBZA sensor covers a zone of approximately onelane over from both sides of the vehicle, 3.5 m (11 ft).This zone starts at each side mirror and goes backapproximately 5 m (16 ft). The height of the zone isapproximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) offthe ground.
The SBZA detection zones do not change if the vehicleis towing a trailer. So be extra careful when changinglanes while towing a trailer.
How the System Works
When the vehicle is started, both outside mirror displayswill briefly come on to indicate that the system isoperating. While driving forward, the left or right sidemirror SBZA display will light up if a vehicle is detected inthat blind zone. If you activate a turn signal and a vehiclehas been detected on the same side, the SBZA displaywill flash to give you extra warning not to change lanes.
SBZA displays do not come on while the vehicle isapproaching or passing other vehicles. At speedsgreater then 20 mph (32 km/h), SBZA displays maycome on when a vehicle you have passed remains in ordrops back into the detection zone.
SBZA can be disabled through the Driver InformationCenter (DIC). SeeDriver Information Center (DIC)on page 4-61for more information. If the SBZAis disabled by the driver, the SBZA mirror displays willnot light up during normal driving.

WARNING: (Continued)
LDW will indicate the system is working whenever
it detects either the left or right lane marking. So if
you depart on the side of the lane that LDW is not
detecting, LDW will not warn you.
If you do not carefully maintain your vehicle
position within the lane, vehicle damage, injury, or
death could occur. Even with LDW, always keep
your attention on the road and maintain proper
vehicle position within the lane. Always keep the
windshield clean and do not use LDW in bad
weather conditions.
When the vehicle crosses a detected lane marking, theLDW symbol will flash and you will hear three beeps.LDW will not warn you if the turn signal is on or ifyou make a sharp maneuver. Before making a lanechange, check the vehicle’s mirrors, glance over yourshoulder for vehicles and hazards, and start theturn signal before changing lanes.
How the System Works
LDW uses a camera located between the insiderearview mirror and the windshield to detect the lanemarkings.
@(Lane Departure Warning):To turn LDW on and
off, press the LDW control, located by the exteriorheadlamp control. An indicator on the control will light toindicate that LDW is on.
When the vehicle is started, the LDW symbol, located inthe instrument panel cluster, will briefly come on toindicate that the light is operational.
LDW only operates at speeds of 35 mph (56 km) orgreater. If LDW is turned on when traveling at thesespeeds, the LDW symbol will appear green if the systemdetects a left or right lane marking.

FCA is enabled when the green light on the button is lit.FCA is disabled when the indicator light is amber.
{WARNING:
•On winding roads, FCA may not detect a
vehicle ahead. You could crash into a vehicleahead of you. Do not rely on FCA onwinding roads.
•When weather limits visibility, such as in fog,
rain, or snow, FCA performance is limited.There may not be enough warning distance tothe vehicle in front of you. Do not rely onFCA in low visibility conditions.
{WARNING:
When FCA is enabled, the Adaptive Cruise
Control switch is on. If you press another Adaptive
Cruise Control button, you might go into cruise
when you do not want to. You could be startled
and even lose control. Be careful not to press
adaptive cruise buttons unless you want to use
cruise control.
Alerting the Driver
The FCA alert symbol willflash and a warning beepwill sound when driveraction may be required.
The alert symbol will flash when:
•Your vehicle is approaching another vehicle too
quickly.
•Your vehicle is following a vehicle ahead of you
much too closely.
SeeDefensive Driving on page 5-2for more information.
Detecting the Vehicle Ahead
The vehicle ahead symbol, located next to the FCAsymbol, will only appear when a vehicle ahead of you isdetected in your path. If this symbol does not appear,or disappears briefly, FCA will not respond to vehiclesyou may see ahead. The symbol may disappear oncurves, highway exit ramps, or hills. Also, when anothervehicle enters the same lane as you, the FCA systemwill not detect the vehicle until it is completely inyour driving lane.
