Light” will no longer flash, theCHECK TPM SYSTEM
text message will no longer display, and a pressure value
will be displayed instead of dashes.
NOTE:In the event that the matching full size spare tire
is swapped with a low pressure road tire, the next
ignition key cycle will still show the “Tire Pressure
Monitoring Telltale Light” to be ON, a chime to sound, a
Low Pressure message to appear in the EVIC, and the
graphic display will still show the low tire pressure value
flashing. Driving the vehicle for up to 10 minutes above
15 mph (24 km/h) will turn off the “Tire Pressure
Monitoring Telltale Light” as long as the matching full
size spare tire or any other road tire(s) are not below the
low pressure warning threshold. The EVIC will display a
“Spare Low Pressure” text message, and the graphic
display will show a new tire pressure value in place of
the flashing low tire pressure value.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to
the sensors may result.

NOTE:The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to the Tire–
Safety Information section in this manual.
Trailer and Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to swayseverelyside to side
which will cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.Consider the following items when computing the
weight on the rear axle of the vehicle:
•The tongue weight of the trailer.
•The weight of any other type of cargo or equipment
put in or on your vehicle.
•The weight of the driver and all passengers.

leaves, etc. If dirty, clean by gently spraying water from a
garden hose vertically down the face of the A/C con-
denser (if equipped) or the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
Cooling System — Drain, Flush, And Refill
At the intervals shown on the appropriate “Maintenance
Schedule” the system should be drained, flushed, and
refilled.If the coolant solution is dirty or contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner (see your authorized dealer for
recommendations). Follow with a thorough rinsing to
remove all deposits and chemicals. Properly dispose of
old antifreeze/coolant solution.
Selection Of Coolant
Use only the manufacturer’s recommended antifreeze/
coolant, refer to Fluids, Lubricants, and Genuine Parts for
correct antifreeze/coolant type.
