Driving on Grades
Notice:Do not tow on steep continuous gradesexceeding 6 miles (9.6 km). Extended, higherthan normal engine and transmission temperaturesmay result and damage the vehicle. Frequentstops are very important to allow the engine andtransmission to cool.
Reduce speed and shift to a lower gearbeforestartingdown a long or steep downgrade. If the transmission isnot shifted down, the brakes might have to be used somuch that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce thevehicle’s speed to around 45 mph (70 km/h) to reducethe possibility of the engine and the transmissionoverheating. If the engine does overheat, seeEngineOverheating on page 6-27.
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.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)yet. Turn the wheels into the curb if facing downhillor into traffic if facing uphill.

Notice:Using abrasive cleaners when cleaningglass surfaces on the vehicle, could scratchthe glass and/or cause damage to the rear windowdefogger. When cleaning the glass on the vehicle,use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may becomeconcentrated in the vehicle’s breathing space. Beforeusing cleaners, read and adhere to all safety instructionson the label. While cleaning the vehicle’s interior,maintain adequate ventilation by opening the vehicle’sdoors and windows.
Dust may be removed from small buttons and knobsusing a small brush with soft bristles.
Products that remove odors from the vehicle’supholstery and clean the vehicle’s glass can be obtainedfrom your dealer/retailer.
Do not clean the vehicle using:
•A knife or any other sharp object to remove a soil
from any interior surface.
•A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
•Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damagethe interior and does not improve the effectivenessof soil removal.
•Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks andattracts dirt. For liquid cleaners, about 20 drops pergallon (3.78 L) of water is a good guide. Useonly mild, neutral-pH soaps.
•Too much cleaner that saturates the upholstery.
•Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachmentfrequently to remove dust and loose dirt. A canistervacuum with a beater bar in the nozzle may onlybe used on floor carpet and carpeted floor mats. Forany soil, always try to remove it first with plain water orclub soda. Before cleaning, gently remove as muchof the soil as possible using one of the followingtechniques:
•For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into thepaper towel until no more can be removed.
•For solid dry soils: remove as much as possible
and then vacuum.
