4. After refueling, reinstall the fuelcap by turning it clockwise until it
clicks. Close the fuel door.
{WARNING
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. Do not top off or overfill the tank and
wait a few seconds before removing
the nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑85.{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Notice:
If a new fuel cap is
needed, be sure to get the right
type of cap from your dealer. The
wrong type of fuel cap might not
fit properly, might cause the
malfunction indicator lamp to
light, and could damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑19.

{WARNING
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
DEX-COOL coolant mixture at the
coolant surge tank.
The coolant surge tank pressure
cap can be removed when the
cooling system, including the surge
tank pressure cap and upper
radiator hose, is no longer hot.
1. Turn the pressure cap slowly
counterclockwise. If a hiss is
heard, wait for that to stop.
A hiss means there is still some
pressure left.
2. Keep turning the cap and remove it.
3. Fill the coolant surge tank with
the proper mixture to the cold
fill line.
4. Replace the pressure cap. Be sure the pressure cap is
hand‐tight and fully seated.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.

When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for five minutes.
This will help to inflate the tire
faster.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers. SeeHazard
Warning Flashers on page 6‑3.
See If a Tire Goes Flat on
page 10‑65 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑74.
2. Unwrap the sealant/air hose (F) and the power plug (H). 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.
6. Plug the power plug (H) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets on page 5‑8.
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 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 10‑50. 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 on
page 13‑6.
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.
