TOWING A TRAILER - MACH 1
WARNING: Your vehicle isnot approved for trailer towing.Never tow a trailer with yourvehicle.
TOWING A TRAILER
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Towing trailersbeyond the maximumrecommended gross trailerweight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss ofvehicle control, vehicle rolloverand personal injury.
Note:There may be electricalitems such as fuses or relays thatcan affect trailer towing operation.See Fuses (page 246).
The load capacity of your vehicleis designated by weight notvolume. You may not necessarilybe able to use all available spacewhen loading your vehicle ortrailer.
Towing a trailer places extra loadon the engine, transmission, axle,brakes, tires, and suspension.Inspect these components before,during and after towing.
Load Placement
To help minimize how trailermovement affects the vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest items in thecenter of the left and right sidetrailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to go
above or below 10-15% of theloaded trailer weight.
•Select a ball mount with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward thevehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibration
or shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in the Load Carryingchapter. See Load Limit (page214).

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 thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•Switch off the speed control withheavy loads or in hilly terrain. Thespeed control may turn offautomatically when you are towing onlong, 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 andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a slope. However, ifyou must park on a slope:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.
2.Set your vehicle parking brake.
3.Place the automatic transmission inpark (P) or manual transmission in alow gear.
4.Place wheel chocks in front and backof the 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 torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Any time the rear axle submerges in water,replace the rear axle lubricant. Water maycontaminate the rear axle lubricant, whichis not a normal maintenance inspectionitem unless there is a possibility of a leakor other axle repair is required.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 90).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine continues to operatewith limited power for a short period oftime.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1.Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2.Immediately switch the engine off toprevent severe engine damage.
3.Wait for the engine to cool down.
4.Check the coolant level. See EngineCoolant Check (page 265).
5.Have your vehicle checked as soon aspossible.
Reduced Vehicle Top Speed
Your vehicle's ability to reach and maintaintop speed is partially dependent uponambient temperature. Under certainenvironmental conditions, your vehicle'stop speed may be reduced to protectpowertrain components.
COLD WEATHER
PRECAUTIONS
The functional operation of somecomponents and systems can be affectedat temperatures below approximately-13°F (-25°C).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid drivingat high speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
Ground Clearance
Since ground clearance is reduced, usecaution when approaching curbs or curbstops from the front and rear as vehicledamage may occur. Additionally, whencrossing speed bumps or driveway curbs,you should approach at a 45 degree angleto reduce the risk of vehicle damage.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoidheavy braking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
