Note:You do not need to enter an exacttrailer width measurement. You only needto confirm that the width of the trailer is 8.5 ft(2.6 m) or less.
•Trailer length measurement:
The trailer length is the distance betweenthe trailer hitch ball and the rear of the trailer.The maximum length that the system cansupport is 33 ft (10.1 m).
•Enter length of trailer:
The default setting is 18 ft (5.5 m). Togglingup or down using the menu buttonsincreases or decreases the measurement by3 ft (1 m). Select a length that is equal to orwithin 3 ft (1 m) of the actual measuredlength. For example, if the actual measuredlength is 25 ft (7.6 m), toggle the length inthe menu to 27 ft (8.2 m). When you enterthe length of the trailer, the system setup issaved.
Note:If the trailer is actually a bike rack orcargo rack with electrical lighting, enter alength of 3 ft (1 m). Cross Traffic Alert remainson for trailers with a length of 3 ft (1 m) orless.
Note:Proper measurement andmeasurement entry is required for thesystem to function as designed.
System Operation
When you connect a trailer to your vehicle,the trailer set up menu appears in theinformation display. This menu allows you toset up a new trailer or choose from apreviously set up trailer. A warning messageappears and the system turns off if you donot choose or add a new trailer.
Note:The warning message may not appearuntil your vehicle speed reaches 22 mph(35 km/h).
If you select a trailer in the informationdisplay before connecting a trailer to yourvehicle, the system loads the configurationfor the selected trailer. When a trailer isconnected, a warning message appears.
Note:A second warning message mayappear stating that the Cross Traffic Alertsystem has turned off. The Blind SpotInformation System with Trailer Towcontinues to function normally in thissituation.
Note:The system remembers the lastselected trailer set up when you start yourvehicle.
Trailer Considerations
The system is designed to work with a trailerwith a front width of 8.5 ft (2.6 m) or less, anda total length from the trailer hitch ball to therear of the trailer of 33 ft (10.1 m) or less.
Some trailers may cause a slight change insystem performance:
•Large box trailers may cause false alertsto occur when driving next toinfrastructures or near parked cars. Afalse alert may also occur while makinga 90-degree turn.
•Trailers that have a width greater than8.5 ft (2.6 m) at the front and have a totallength greater than 20 ft (6 m) may causedelayed alerts when a vehicle is passingat high speed.

If a steering systemwarning message returns, have the systemchecked by an authorized dealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

LOAD LIMIT
Vehicle Loading - with and without aTrailer
This section guides you in the properloading of your vehicle, trailer, or both.Keep your loaded vehicle weight withinits design rating capability, with orwithout a trailer. Properly loading yourvehicle provides maximum return ofvehicle design performance. Before youload your vehicle, become familiar withthe following terms for determining yourvehicle’s weight rating, with or withouta trailer, from the vehicle’s Tire andLoading Information label or SafetyCompliance Certification label.
Tire and Loading Label InformationExample:Payload
Payload is the combined weight of cargoand passengers that your vehicle iscarrying. The maximum payload for yourvehicle appears on the Tire and Loadinglabel. The label is either on the B-pillaror the edge of the driver door. Vehiclesexported outside the US and Canadamay not have a tire and loading label.Look for “The combined weight ofoccupants and cargo should neverexceed XXX kg OR XXX lb” formaximum payload. The payload listedon the Tire and Loading Informationlabel is the maximum payload for yourvehicle as built by the assembly plant. Ifyou install any additional equipment onyour vehicle, you must determine thenew payload. Subtract the weight of the
equipment from the payload listed onthe Tire and Loading label. When towing,trailer tongue weight or king pin weightis also part of payload.

Load CarryingE198719

WARNING: The appropriateloading capacity of your vehicle canbe limited either by volume capacity(how much space is available) or bypayload capacity (how much weightthe vehicle should carry). Once youhave reached the maximum payloadof your vehicle, do not add morecargo, even if there is space available.Overloading or improperly loadingyour vehicle can contribute to loss ofvehicle control and vehicle rollover.
GAWR (Gross Axle Weight Rating)
GAWR is the maximum allowable weightthat a single axle (front or rear) can carry.These numbers are on the SafetyCompliance Certification label. The labelis located on the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver seating position.
The total load on each axle must neverexceed its Gross Axle Weight Rating.
GVWR (Gross Vehicle Weight Rating)
GVWR is the maximum allowable weightof the fully loaded vehicle. This includesall options, equipment, passengers andcargo. It appears on the SafetyCompliance Certification label. The labelis located on the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver seating position.
The gross vehicle weight must neverexceed the Gross Vehicle Weight Rating.
Safety Compliance Certification LabelExample:
WARNING: Exceeding the SafetyCompliance Certification label vehicleweight limits can adversely affect theperformance and handling of yourvehicle, cause vehicle damage andcan result in the loss of control of yourvehicle, serious personal injury ordeath.
Maximum Loaded Trailer Weight
Maximum loaded trailer weight is thehighest possible weight of a fully loadedtrailer the vehicle can tow. Consult anauthorized dealer (or the RV and TrailerTowing Guide available at an authorizeddealer) for more detailed information.
GCWR (Gross Combined WeightRating)
GCWR is the maximum allowable weightof the vehicle and the loaded trailer,including all cargo and passengers, thatthe vehicle can handle without riskingdamage. (Important: The towingvehicle’s braking system is rated for

operation at Gross Vehicle WeightRating, not at Gross Combined WeightRating.) Separate functional brakesshould be used for safe control of towedvehicles and for trailers where the GrossCombined Weight of the towing vehicleplus the trailer exceed the Gross VehicleWeight Rating of the towing vehicle.
The gross combined weight must neverexceed the Gross Combined WeightRating.
Note: For trailer towing informationrefer to the RV and Trailer Towing Guideavailable at an authorized dealer.
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
WARNING: Do not usereplacement tires with lower loadcarrying capacities than the originaltires because they may lower yourvehicle's GVWR and GAWR limitations.Replacement tires with a higher limitthan the original tires do not increasethe GVWR and GAWR limitations.
WARNING: Exceeding anyvehicle weight rating can adverselyaffect the performance and handlingof your vehicle, cause vehicle damageand can result in the loss of control ofyour vehicle, serious personal injuryor death.
Steps for determining the correct loadlimit:
1.Locate the statement "The combinedweight of occupants and cargoshould never exceed XXX kg or XXXlb." on your vehicle’s placard.
2.Determine the combined weight ofthe driver and passengers that willbe riding in your vehicle.
3.Subtract the combined weight of thedriver and passengers from XXX kgor XXX lb.
4. The resulting figure equals theavailable amount of cargo andluggage load capacity. For example,if the “XXX” amount equals 1,400 lb.and there will be five 150 lb.passengers in your vehicle, theamount of available cargo andluggage load capacity is 650 lb.(1400-750 (5 x 150) = 650 lb.)
5.Determine the combined weight ofluggage and cargo being loaded onthe vehicle. That weight may not
safely exceed the available cargoand luggage load capacity calculatedin Step 4.

6.If your vehicle will be towing a trailer,load from your trailer will betransferred to your vehicle. Consultthis manual to determine how thisreduces the available cargo andluggage load capacity of yourvehicle.
Helpful examples for calculating theavailable amount of cargo andluggage load capacity
Suppose your vehicle has a 1400-pound(635-kilogram) cargo and luggagecapacity. You decide to go golfing. Isthere enough load capacity to carry you,four of your friends and all the golf bags?You and four friends average 220pounds (99 kilograms) each and the golfbags weigh approximately 30 pounds
(13.5 kilograms) each. The calculationwould be: 1400 - (5 x 220) - (5 x 30) =1400 - 1100 - 150 = 150 pounds. Yes, you
have enough load capacity in yourvehicle to transport four friends and yourgolf bags. In metric units, the calculationwould be: 635 kilograms - (5 x 99kilograms) - (5 x 13.5 kilograms) = 635 -495 - 67.5 = 72.5 kilograms.
Suppose your vehicle has a 1400-pound(635-kilogram) cargo and luggagecapacity. You and one of your friendsdecide to pick up cement from the localhome improvement store to finish thatpatio you have been planning for thepast two years. Measuring the inside ofthe vehicle with the rear seat foldeddown, you have room for twelve100-pound (45-kilogram) bags ofcement. Do you have enough loadcapacity to transport the cement to yourhome? If you and your friend each weigh
220 pounds (99 kilograms), thecalculation would be: 1400 - (2 x 220) -(12 x 100) = 1400 - 440 - 1200 = - 240pounds. No, you do not have enoughcargo capacity to carry that muchweight. In metric units, the calculationwould be: 635 kilograms - (2 x 99kilograms) - (12 x 45 kilograms) = 635 -
198 - 540 = -103 kilograms. You will needto reduce the load weight by at least240 pounds (104 kilograms). If youremove three 100-pound (45-kilogram)cement bags, then the load calculationwould be:1400 - (2 x 220) - (9 x 100) =1400 - 440 - 900 = 60 pounds. Now youhave the load capacity to transport thecement and your friend home. In metricunits, the calculation would be: 635kilograms - (2 x 99 kilograms) - (9 x 45kilograms) = 635 - 198 - 405 = 32kilograms.
The above calculations also assume thatthe loads are positioned in your vehiclein a manner that does not overload thefront or the rear gross axle weight ratingspecified for your vehicle on the SafetyCompliance Certification label.
