Adaptive Learning
The electronic power steering systemadaptive learning helps correct roadirregularities and improves overall handlingand steering feel. It communicates with thebrake system to help operate advancedstability control and accident avoidancesystems. Additionally, whenever the batteryis disconnected or a new battery installed,you must drive your vehicle a short distancebefore the system relearns the strategy andreactivates all systems.
PRE-COLLISION ASSIST (If Equipped)
WARNINGS
At all times, you are responsible forcontrolling your vehicle, supervisingthe system and intervening, if required.Failure to take care may result in the loss ofcontrol of your vehicle, serious personalinjury or death.
WARNINGS
The system is designed to aid thedriver. It is not intended to replace yourattention and judgment. You are stillresponsible to drive with due care andattention.

The system does not operate duringhard acceleration or steering. Failureto take care may lead to a crash or personalinjury.
The system may fail or operate withreduced function during cold andsevere weather conditions. Snow, ice, rain,spray and fog can adversely affect thesystem. Keep the front camera and radar freeof snow and ice. Failure to take care mayresult in the loss of control of your vehicle,serious personal injury or death.
WARNINGS
In situations where the vehicle camerahas limited detection capability, thismay reduce system performance. Thesesituations include but are not limited to director low sunlight, vehicles at night without taillights, unconventional vehicle types,pedestrians with complex backgrounds,running pedestrians, partly obscuredpedestrians, or pedestrians that the systemcannot distinguish from a group. Failure totake care may result in the loss of control ofyour vehicle, serious personal injury or death.
The system cannot help prevent allcrashes. Do not rely on this system toreplace driver judgment and the need tomaintain a safe distance and speed.

Driving Aids

If your vehicle is rapidly approaching anotherstationary vehicle, a vehicle traveling in thesame direction as yours, or a pedestrianwithin your driving path, the system isdesigned to provide three levels offunctionality:
1. Alert
2. Brake Support
3. Active Braking
Alert: When activated, a red warning lightflashes, an audible warning chime soundsand a warning message shows in theinformation display.
Brake Support: Assists the driver in reducingcollision speed by preparing the brakesystem for rapid braking. Brake support doesnot automatically activate the brakes, but ifthe brake pedal is pressed even lightly bythe driver, brake support could addadditional braking up to full force.
Active Braking: Active braking may activateif the system determines that a collision isimminent. The system may help the driverreduce impact damage or avoid the crashcompletely.
Note:If you perceive Pre-Collision Assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity,though the manufacturer recommends usingthe highest sensitivity setting where possible.Setting lower sensitivity would lead to fewerand later system warnings.
Adjusting the Pre-Collision Assist Settings
You can adjust the Pre-Collision Assistsettings by using the information displaycontrol. See General Information (page 111).
If required, you can switch active braking offusing the information display control. SeeGeneral Information (page 111).
Note:Active braking automatically turns onevery time you switch the ignition on.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or theGAWR specified on the certificationlabel.
Towing trailers beyond themaximum recommended grosstrailer weight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
Note:There may be electrical itemssuch as fuses or relays that can affect
trailer towing operation. See Fuses(page 282).
The load capacity of your vehicle isdesignated by weight not volume. Youmay not necessarily be able to use allavailable space when loading yourvehicle or trailer.
Towing a trailer places extra load on theengine, transmission, axle, brakes, tires,and suspension. Inspect thesecomponents before, during and aftertowing.
Load Placement
To help minimize how trailer movementaffects the vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items in the centerof the left and right side trailer tires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight.
•Select a ball mount with the correctrise or drop. When both the loadedvehicle and trailer are connected, thetrailer frame should be level, orslightly angled down toward thevehicle, when viewed from the side.
When driving with a trailer or payload, aslight takeoff vibration or shudder maybe present due to the increased payloadweight. Additional information regardingproper trailer loading and setting yourvehicle up for towing is located in theLoad Carrying chapter. See Load Limit(page 251).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.

•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
There are also some things you may want toavoid doing because they reduce your fueleconomy:
•Avoid sudden or hard accelerations.
•Avoid revving the engine before turningoff the car.

ENGINE COOLANT CHECK
WARNINGS
Never remove the coolant reservoircap when the engine is running or hot.
Do not put coolant in the windshieldwasher reservoir. If sprayed on thewindshield, coolant could make it difficult tosee through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressure relief cap.The cooling system is under pressure. Steamand hot liquid can come out forcefully whenyou loosen the cap slightly.
WARNINGS
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 509).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We recommend,Robinair® Coolant and Battery Refractometer75240 (Rotunda tool part number:ROB75240). We do not recommend the useof hydrometers or coolant test strips formeasuring coolant concentration.
