CAUTION!(Continued)
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting And Oper-
ating” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pres-
sures before trailer usage. •
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting And Operating” for the
proper inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting And Operating” for the proper
tire replacement procedures. Replacing tires with a
higher load carrying capacity will not increase the
vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically

STARTING AND OPERATING 539

NOTE:There are steps that you can take to slow down
an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

Using The Power ButtonPush and release the Power Button (4) once to
turn On the TIREFIT kit. Push and release the
Power Button (4) again to turn Off the TIREFIT
kit.
Using The Deflation Button
Press the Deflation Button (2) to reduce the air
pressure in the tire if it becomes over-inflated.
TIREFIT Usage Precautions
•Replace the TIREFIT Sealant Bottle (1) and Sealant
Hose (6) prior to the expiration date (printed at the
lower right hand corner on the bottle label) to assure
optimum operation of the system. Refer to “Sealing a
Tire with TIREFIT” section (F) “Sealant Bottle and
Hose Replacement”. •
The Sealant Bottle (1) and Sealant Hose (6) are a one
tire application use and need to be replaced after each
use. Always replace these components immediately at
your original equipment vehicle dealer.
• When the TIREFIT sealant is in a liquid form, clean
water, and a damp cloth will remove the material fromTIREFIT Expiration Date Location

the vehicle or tire and wheel components. Once the
sealant dries, it can easily be peeled off and properly
discarded.
• For optimum performance, make sure the valve stem
on the wheel is free of debris before connecting the
TIREFIT kit.
• You can use the TIREFIT air pump to inflate bicycle
tires. The kit also comes with two needles, located in
the Accessory Storage Compartment (on the bottom of
the air pump) for inflating sport balls, rafts, or similar
inflatable items. However, use only the Air Pump Hose
(7) and make sure the Mode Select Knob (5) is in the
Air Mode when inflating such items to avoid injecting
sealant into them. The TIREFIT Sealant is only in-
tended to seal punctures less than ¼” (6 mm) diameter
in the tread of your vehicle.
• Do not lift or carry the TIREFIT kit by the hoses.WARNING!
•Do not attempt to seal a tire on the side of the
vehicle closest to traffic. Pull far enough off the
road to avoid the danger of being hit when using
the TIREFIT kit.
• Do not use TIREFIT or drive the vehicle under the
following circumstances:
– If the puncture in the tire tread is approximately 1/4” (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with extremely low tire pressure.
– If the tire has any damage from driving on a flat tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or the wheel.

3. The Sealant Bottle (1) may be empty due to previous use. Call for assistance. NOTE:
If the Mode Select Knob (5) is on Air Mode and
the pump is operating, air will dispense from the Air
Pump Hose (7) only, not the Sealant Hose (6).
If the sealant (white fluid) does flow through the
Sealant Hose (6):
1. Continue to operate the pump until sealant is no longer flowing through hose (typically takes 30 -
70 seconds). As the sealant flows through the Sealant
Hose (6), the Pressure Gauge (3) can read as high as 70
psi (4.8 Bar). The Pressure Gauge (3) will decrease
quickly from approximately 70 psi (4.8 Bar) to the
actual tire pressure when the Sealant Bottle (1) is
empty.
2. The pump will start to inject air into the tire immedi- ately after the Sealant Bottle (1) is empty. Continue to
operate the pump and inflate the tire to the pressure
indicated on the tire pressure label on the driver-side

latch pillar (recommended pressure). Check the tire
pressure by looking at the Pressure Gauge (3).
If the tire does not inflate to at least 26 psi (1.8 Bar)
pressure within 15 minutes:
• The tire is too badly damaged. Do not attempt to drive
the vehicle further. Call for assistance.
NOTE: If the tire becomes over-inflated, press the Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
If the tire inflates to the recommended pressure or is at

2. Remove the Speed Limit sticker from the top of the Sealant Bottle (1) and place the sticker on the instru-
ment panel. 3. Immediately disconnect the Sealant Hose (6) from the
valve stem, reinstall the cap on the fitting at the end of
the hose, and place the TIREFIT kit in the vehicle
storage location. Quickly proceed to (D) “Drive Ve-
hicle.”
CAUTION!
•The metal end fitting from Power Plug (8) may get
hot after use, so it should be handled carefully.
• Failure to reinstall the cap on the fitting at the end
of the Sealant Hose (6) can result in sealant con-
tacting your skin, clothing, and the vehicle’s inte-
rior. It can also result in sealant contacting internal
Tire Service Kit components which may cause
permanent damage to the kit.
