{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.
If the DMCM coolant is empty, your vehicle must be
serviced by your dealer and a special fill procedure
must be followed.
Notice:Attempting to ll the DMCM cooling surge
tank yourself when the uid level is empty can
damage your vehicle. Your vehicle must be serviced.1. Park the vehicle on a level surface and turn the
vehicle off. Remove the DMCM coolant surge
tank pressure cap when the DMCM cooling system,
including the DMCM coolant surge tank pressure
cap and DMCM cooling hoses, are no longer hot.
Turn the DMCM coolant surge tank pressure cap
slowly counterclockwise (left) about one full turn.
Wait 30 seconds.

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inate a
Punctured Tire
Follow the directions closely for correct sealant usage.
When using the tire sealant and compressor kit during
cold temperatures, warm the kit in a heated environment
for 5 minutes. This will help to inflate the tire faster.Always do a safety check first. SeeIf a Tire Goes Flat
on page 5-30
1. Remove the tire sealant and compressor kit from its
storage location. SeeTire Sealant and Compressor
Kit Storage on page 5-50
Make sure the on/off button (D) is in the off (O)
position.
2. Unwrap the sealant/air hose (F) and the power
plug (C).
3. Place the kit on the ground.
Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.
5-35

11. Unplug the power plug (C) from the accessory
power outlet in the vehicle.
12. Turn the sealant/air hose (F) counterclockwise to
remove it from the tire valve stem.
13. Replace the tire valve stem cap.
14. Replace the sealant/air hose (F), and the power
plug (C) back in their original location.
15. If the flat tire was able
to inflate to the
recommended inflation
pressure, remove
the maximum speed
label from the sealant
canister (B) and
place it in a highly
visible location.
The label is a reminder not to exceed 55 mph
(90 km/h) until the damaged tire is repaired
or replaced.16. Return the equipment to its original storage location
in the vehicle.
17. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.
18. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inflate a Tire (Not Punctured).”
If the tire pressure has fallen more than 10 psi
(68 kPa) below the recommended inflation pressure,
stop driving the vehicle. The tire is too severely
damaged and the tire sealant cannot seal the tire.
See “Roadside Assistance Program” in the
owner manual.
If the tire pressure has not dropped more than
10 psi (68 kPa) from the recommended inflation
pressure, inflate the tire to the recommended
inflation pressure.

9. Start the vehicle. The vehicle must be running
while using the air compressor.
10. Press the on/off (D) button to turn the
compressor on.
The compressor will inflate the tire with air only.
11. Inflate the tire to the recommended inflation pressure
using the pressure gage (E). The recommended
inflation pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-24.
The pressure gage (E) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate reading.
The compressor may be turned on/off until the
correct pressure is reached.
