In Brief 1-21
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
to a significant loss in pressure of
one of the vehicle's tires. If the
warning light comes on, stop as
soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. SeeVehicle Load
Limits on page 9‑12. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑47.Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to temporarily seal small punctures
in the tread area of the tire.
See Tire Sealant and Compressor
Kit on page 10‑63 for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat on
page 10‑61.

Driving and Operating 9-51
When towing at high altitude on
steep uphill grades, engine coolant
will boil at a lower temperature than
at normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle may show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10‑19.
On a long uphill grade, shift down
and reduce the vehicle speed to
around 88 km/h (55 mph) to reduce
the possibility of the engine and the
transmission overheating.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
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.Start the engine.
.Shift into a gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

{WARNING
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area
that has no fresh air ventilation.
For more information, seeEngine
Exhaust on page 9‑24.
{WARNING
Overinflating a tire could cause
the tire to rupture and you
or others could be injured.
Be sure to read and follow the
tire sealant and compressor kit
instructions and inflate the tire
to its recommended pressure.
Do not exceed the recommended
pressure.
{WARNING
Storing the tire sealant and
compressor kit or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store the tire
sealant and compressor kit in
its original location. If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (¼ in) in the
tread area of the tire. It can also be
used to inflate an underinflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire is
too severely damaged for the tire
sealant and compressor kit to be
effective. See
Roadside Assistance
Program (U.S. and Canada) on
page 13‑8 orRoadside Assistance
Program (Mexico) on page 13‑10.
Read and follow all of the tire
sealant and compressor kit
instructions.

7. Start the vehicle. The vehiclemust be running while using the
air compressor.
8. Turn the selector switch (A) counterclockwise to the
Sealant + Air position.
9. Press the on/off button (B) to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gauge (C) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only. 10. Inflate the tire to the
recommended inflation
pressure using the pressure
gauge (C). The recommended
inflation pressure can be
found on the Tire and Loading
Information label. See Tire
Pressure on page 10‑45.
The pressure gauge (C) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate pressure
reading. The compressor may
be turned on/off until the
correct pressure is reached.
Notice: If the recommended
pressure cannot be reached
after approximately 25 minutes,
the vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot inflate the tire. Remove the power plug
from the accessory power
outlet and unscrew the inflating
hose from the tire valve. See
Roadside Assistance Program
(U.S. and Canada) on page 13‑8
or
Roadside Assistance Program
(Mexico) on page 13‑10.
11. Press the on/off button (B) to turn the tire sealant and
compressor kit off.
The tire is not sealed and
will continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire;
therefore, Steps 12 through 18
must be done immediately after
Step 11.
Be careful while handling the
tire sealant and compressor
kit as it could be warm after
usage.
