{CAUTION:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overll the
tank and wait a few seconds after you have nished
pumping before removing the nozzle. Clean fuel
from painted surfaces as soon as possible. See
Washing Your Vehicle on page 5-107.
When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. This would allow fuel to evaporate
into the atmosphere. SeeMalfunction Indicator Lamp on
page 3-38.There may also be a light that comes on in the
instrument panel to let you know if the gas cap is not
properly installed. SeeCheck Gas Cap Light on
page 3-47for more information.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel by
shutting off the pump or by notifying the station
attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one
for you. If you get the wrong type, it may not t
properly. This may cause the malfunction indicator
lamp to light and may damage the fuel tank and
emissions system. SeeMalfunction Indicator Lamp
on page 3-38.

How to Add Coolant to the Radiator
{CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the surge tank
pressure cap — even a little — they can come out
at high speed. Never turn the cap when the cooling
system, including the surge tank pressure cap, is
hot. Wait for the cooling system and surge tank
pressure cap to cool if you ever have to turn the
pressure cap.If coolant is needed, add the proper mixture directly to
the radiator, but be sure the cooling system is cool
before this is done.
1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap
and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise about
one full turn. If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure left.
2. Then keep turning the pressure cap. Remove the
pressure cap.

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 at tire by
turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve
stem. Turn it clockwise until it is tight.
6. Plug the power plug (H) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. SeeAccessory Power
Outlet(s) on page 3-18.
If the vehicle has an accessory power outlet, do not
use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.7. Start the vehicle. The vehicle must be running while
using the air compressor.
8. Turn the selector switch (A) counterclockwise to the
Sealant + Air position.
9. Press the on/off (B) button to turn the tire sealant
and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (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 inates with air only.
5-81

10. Inate the tire to the recommended ination pressure
using the pressure gage (C). The recommended
ination pressure can be found on the Tire and
Loading Information label. SeeInflation - Tire
Pressure on page 5-60.
The pressure gage (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 inate the tire. Remove the power plug from
the accessory power outlet and unscrew the inating
hose from the tire valve. SeeRoadside Assistance
Program on page 7-7.
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.12. Unplug the power plug (H) from the accessory
power outlet in the vehicle.
13. Turn the sealant/air hose (F) counterclockwise to
remove it from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F), and the power
plug (H) back in their original location.
16. If the at tire was
able to inate to the
recommended ination
pressure, remove the
maximum speed label
from the sealant
canister (E) 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.
17. Return the equipment to its original storage location
in the vehicle.
18. Immediately drive the vehicle 5 miles (8 km) to
distribute the sealant in the tire.

The compressor may be turned on/off until the
correct pressure is reached.If you inate the tire higher than the recommended
pressure you can adjust the excess pressure by
pressing the pressure deation button (D), if
equipped, until the proper pressure reading is
reached. This option is only functional when using
the air only hose (G).
