204 Driving and Operating
Passing
More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.
If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergearbeforestarting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.
Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.
The Tow/Haul Mode may be used ifthe transmission shifts too often.SeeTo w / H a u l M o d e0187.
When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil atalowertemperaturethanatnormalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with thetransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0230.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.

Overload
The vehicle has fuses and circuitbreakers to protect against anelectrical system overload.
When the current electrical load istoo heavy, the circuit breaker opensand closes, protecting the circuituntil the current load returns tonormal or the problem is fixed. Thisgreatly reduces the chance of circuitoverload and fire caused byelectrical problems.
Fuses and circuit breakers protectpower devices in the vehicle.
Replace a bad fuse with a new oneof the identical size and rating.
If there is a problem on the road andafuseneedstobereplaced,thesame amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon as possible.
