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 Safety
Compliance 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 rating limits could result insubstandard vehicle handling orperformance, engine, transmissionand/or structural damage, seriousdamage to the vehicle, loss of controland personal injury.
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 foroperation at Gross Vehicle WeightRating, not at Gross Combined Weight
Rating.) 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.

TOWING A TRAILER
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
WARNING: Towing trailers beyondthe maximum 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 affecttrailer towing operation. See Fuses(page 277).
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 248).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.

Towing

Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Before Towing a Trailer
Practice turning, stopping and backing up toget the feel of your vehicle-trailercombination before starting on a trip. Whenturning, make wider turns so the trailerwheels clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speed controlmay turn off automatically when you aretowing on long, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy and transmissioncooling.
•Allow more distance for stopping with atrailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back ofthe trailer wheels. Chocks are notincluded with your vehicle.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level to riseabove the bottom edge of the rearbumper.
•Do not allow waves to break higher than6 in (15 cm) above the bottom edge ofthe rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
