If you switch the system on in aid or alert andaid mode, a separate white icon alsoappears, or in some vehicles, arrows displaywith the lane markings.
When you switch the system off, the lanemarking graphics do not display.
When the system is on, the color of the lanemarkings change to indicate the systemstatus.
Gray: Indicates that the system is temporarilyunable to provide a warning or interventionon the indicated side. This may be because:
•Your vehicle is under the activationspeed.
•The direction indicator is active.
•Your vehicle is in a dynamic maneuver.
•The road has no or poor lane markingsin the camera field of view.
•The camera is obscured or unable todetect the lane markings due toenvironmental, traffic or vehicleconditions. For example, significant sunangles, shadows, snow, heavy rain or fog,following a large vehicle that is blockingor shadowing the lane or poor headlampillumination.
See Troubleshooting for additionalinformation.
Green: Indicates that the system is availableor ready to provide a warning or interventionon the indicated side.
Yellow: Indicates that the system is providingor has just provided a lane keeping aidintervention.
Red: Indicates that the system is providingor has just provided a lane keeping alertwarning.
The system can be temporarily suppressedat any time by the following:
•Quick braking.
•Fast acceleration.
•Using the turn signal indicator.
•Evasive steering maneuver.
•Driving too close to the lane marking.
Troubleshooting
Why is the feature not available (line markings are gray) when I can see the lane markings on the road?
Your vehicle speed is outside the operational range of the feature.

BLIND SPOT INFORMATION
SYSTEM (If Equipped)
WARNING: Never use the Blind SpotInformation System as a replacement forusing the interior and exterior mirrors orlooking over your shoulder beforechanging lanes. The Blind Spot InformationSystem is not a replacement for carefuldriving.
The Blind Spot Information System isdesigned to aid you in detecting vehiclesthat may have entered the blind spot zone(A). The detection area is on both sides ofyour vehicle, extending rearward from theexterior mirrors to approximately 10 ft (3 m)beyond the bumper. The system is designedto alert you if certain vehicles enter the blindspot zone while driving.
Note:The Blind Spot Information Systemdoes not prevent contact with other vehiclesor objects; nor detect parked vehicles,people, animals or infrastructure (fences,guardrails, trees). It’s only designed to alertyou to vehicles in the blind spot zones.

Page 223 of 575

Note:When a vehicle passes quickly throughthe blind spot zone, typically fewer than twoseconds, the system does not trigger.
Using the System
The Blind Spot Information System turns onwhen you start the engine and you drive yourvehicle forward above 3 mph (5 km/h).
For automatic transmissions, the Blind SpotInformation System remains on while thetransmission is in drive (D). If shifted intoreverse (R) or park (P) the Blind SpotInformation System turns off. Once shiftedback into drive (D), the Blind Spot InformationSystem turns back on when you drive yourvehicle above 3 mph (5 km/h).
For manual transmissions, the Blind SpotInformation System is on for all gears exceptthe reverse (R).
Note:The Blind Spot Information Systemdoes not function in reverse (R) or park (P).
System Lights and Messages
The Blind Spot Information Systemilluminates an amber alert indicator in theoutside mirror on the side of your vehicle theapproaching vehicle is coming from.
The alert indicator dims when the systemdetects nighttime darkness.
System Sensor Blockage
The system uses radar sensors that arelocated behind the bumper fascia on eachside of your vehicle. Any dirt, mud and snowin front of the sensors and/or driving in heavyrain can cause system degradation. Also,other types of obstructions in front of thesensor can cause system degradation. Thisis referred to as a ‘blocked’ condition.
Note:Do not apply bumper stickers and/orrepair compound to these areas, this cancause degraded system performance.

Driving AidsE142442 E205199
Page 224 of 575

If the system detects a degradedperformance condition, a message warningof a blocked sensor will appear in theinformation display. Also the system alertindicators will remain ON and the system willno longer provide any vehicle warnings. Youcan clear the information display warning butthe alert indicators will remain illuminated.
A "blocked" condition can be cleared in twoways:
•After the blockage in front of the sensorsis removed or the rainfall/snowfall ratedecreases or stops, drive for a fewminutes in traffic to allow the sensors todetect passing vehicles.
•By cycling the ignition from ON to OFFand then back ON.
Note:When towing a trailer, the sensors maydetect the trailer thus causing a false alert.It may be desirable to turn the Blind SpotInformation System off if the false alertsbecome annoying.
System Errors
If the system senses a problem with the leftor right sensor, the telltale will illuminate anda message will appear in the informationdisplay. See Information Messages (page112).
System Limitations
The system does have its limitations;situations such as severe weather conditionsor debris build-up on the sensor may limitvehicle detection.
The following are other situations that maylimit the system:
•Certain maneuvering of vehicles enteringand exiting the blind zone.
•Vehicles passing through the blind zoneat very fast rates.
•When several vehicles forming a convoypass through the blind zone.
Switching the System Off and On
You can temporarily switch the Blind SpotInformation System off in the informationdisplay. See General Information (page 105).When the Blind Spot Information Systemswitches off, you will not receive alerts andthe information display shows a system offmessage. The telltale in the cluster alsoilluminates. When you switch the Blind SpotInformation System on or off, the alertindicators flash twice.
Note:The system switches back on everytime you start your vehicle.
You can also have the Blind Spot InformationSystem switched off permanently at anauthorized dealer. Once switched offpermanently, the system can only beswitched back on at an authorized dealer.
