These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident resulting
in serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.

Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of
Methanol.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosionTo fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles. The manufacturer recom-
mends using gasolines without MMT. Since the MMT

•In city traffic —While moving, shift into the highest
gear possible to reduce engine RPM.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the cooling system and turning off the A/C removes this
heat. You can also turn the temperature control to maxi-
mum heat, the mode control to floor, and the fan control
to high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
cooling system.WARNING!
A hot cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. If
your temperature gauge pointer is in the red area,
turn off the engine immediately. You may want to call
a service center for service. If you decide to look
under the hood yourself, see Section 7 of this manual.
Follow the warnings under the “Radiator Cap” para-
graph.
TIREFIT KIT
Small punctures in the tire tread can be sealed with
TIREFIT. Foreign objects (e.g., screws or nails) should not
be removed from the tire. TIREFIT can be used in outside
temperatures down to approximately -4°F (-20°C).

Using the Air Pump Power Button
Push and release the button 3 once to turn ON
the TIREFIT kit. Push and release the button 3
again to turn OFF the TIREFIT kit.
Sealing a Tire with TIREFIT
A. Whenever You Stop to Use TIREFIT
1. Turn ON the vehicle’s hazard warning flashers.
2. Verify that the valve stem (on the wheel with the
deflated tire) is in a position that is near to the ground.
This will allow the TIREFIT Hoses 6 and 7 to reach the
valve stem and keep the TIREFIT kit flat on the ground.
This will provide the best positioning of the kit when
injecting the sealant into the deflated tire and running the
air pump. Move the vehicle as necessary to place the
valve stem in this position before proceeding.3. Place the transmission in PARK (auto transmission) or
in Gear (manual transmission) and turn OFF the ignition.
4. Set the parking brake.
B. Setting Up to Use TIREFIT
1. Remove the gloves from the Accessory Storage Com-
partment 8 and place them on your hands.
2. Turn the Mode Select knob 4 to the Sealant/
Air Mode position.
3. Uncoil the Clear Sealant Hose 7 and then remove the
Yellow Cap from the fitting at the end of the hose.
4. Place the TIREFIT kit flat on the ground next to the
deflated tire.

5. Remove the cap from the valve stem and then screw
the fitting at the end of the Sealant Hose 7 onto the valve
stem.
6. Uncoil the Power Plug and Cable 5 and then insert the
plug into the vehicle’s power outlet.
NOTE:Do not remove foreign objects (e.g., screws or
nails) from the tire.
C. Injecting TIREFIT Sealant into the Deflated Tire
1. Always start the engine before turning ON the TIRE-
FIT kit.
2. After pressing the AIR PUMP POWER
button 3, the air pump should start to inflate
the tire and the sealant (white fluid) will flow
from the Sealant Bottle 1 through the Sealant
Hose 7 and into the tire.NOTE:Some sealant may leak
out through the puncture in the tire.3.If the sealant Does Not Flow Through the Clear
Sealant Hose 7
•Press the AIR PUMP POWER button 3 to turn OFF
the TIREFIT kit. Disconnect the Clear Sealant Hose 7
from the valve stem. Make sure the valve stem is
free of debris. Reconnect the Clear Sealant Hose 7 to
the valve stem. Press the AIR PUMP POWER button
3 to turn ON the TIREFIT kit.
•Turn the Mode Select knob to the Sealant/Air Mode.
•Connect the Power Plug 5 to a different power
outlet in your vehicle or another vehicle, if available.
Make sure the engine is running before turning ON
the TIREFIT kit.
•The Sealant Bottle 1 may be empty due to previous
use. Call for assistance.

WARNING!
TIREFIT is not a permanent flat tire repair. Have the
tire inspected and repaired or replaced after using
TIREFIT. Do not exceed 55 mph (90 km/h) until
having the tire repaired or replaced. Failure to follow
this warning can result in injuries that are serious or
fatal to you, your passengers, and others around you.
F. After Securing TIREFIT Sealant in the Tire
1. Turn the Mode Select knob 4 to the Air
Mode position.
2. Uncoil the Black Air Pump Hose 6 and connect it to the
valve stem.
3. Check the pressure in the tire by reading the Pressure
Gauge 2.
•If the pressure is less than 19 psi (1.3 bar), the tire is
too badly damaged. Do not attempt to drive the
vehicle further. Call for assistance.
•If the pressure is equal to or greater than 19 psi
(1.3 bar), but less than the level indicated on the tire
pressure label, proceed to Step 4 of this procedure.
•If the pressure is at the level indicated on the tire
pressure label on the driver-side latch pillar, proceed
to Step 5 of this procedure.
4. Inflate the tire to the pressure indicated on the tire
pressure label on the driver-side latch pillar.
5. Disconnect the TIREFIT kit from the valve stem and
then reinstall the cap on the valve stem.
6. Place the TIREFIT kit in its proper storage area in the
vehicle.

H. Sealant Bottle Replacement
1. Uncoil the Clear Sealant Hose 7.
2. Locate the rectangular SEALANT BOTTLE RELEASE
button in the recessed area where you place your fingers
to unlatch the hoses 6 and 7 from their storage area.
3. Use the Yellow Cap on end of the Clear Sealant Hose
7 to depress the SEALANT BOTTLE RELEASE button.
The Sealant Bottle 1 will pop up. Remove the bottle and
dispose of it accordingly.
4. Clean any remaining sealant from the TIREFIT hous-
ing.5. Position the new Sealant Bottle 1 to the housing so that
the Clear Sealant Hose 7 aligns with the hose slot in the
front of the housing and the alignment keys on the
bottom of the bottle align with the alignment slots in the
housing. Then, press the bottle into the housing. An
audible click will be heard, indicating the bottle is locked
in place.
6. Verify the Yellow Cap is installed on the fitting at the
end of the Clear Sealant Hose 7 and return the hose to its
storage area.
7. Return the TIREFIT kit to its storage area in the
vehicle.
