Check to see if coolant is visible in
the reservoir. If coolant is visible but
the coolant level is below the cold
fill line, there could be a leak in the
cooling system.
How to Add Coolant to the
Coolant Reservoir
If no problem is found, add the
proper DEX-COOL coolant mixture
at the coolant reservoir.
The coolant reservoir pressure cap
can be removed when the cooling
system, including the pressure cap,
is no longer hot.1. Turn the pressure cap counterclockwise and
remove it.
2. Fill the coolant reservoir with the proper mixture to the cold
fill line on the side of the
reservoir.
3. Reinstall the pressure cap tightly.
Check the level in the coolant
reservoir when the cooling system
has cooled down. If the coolant is
not at the proper level, repeat
Steps 1 and 2, then reinstall the
pressure cap. If the coolant still is
not at the proper level when the
system cools down again, see your
dealer.
Engine Coolant
The engine cooling system in the
vehicle is filled with DEX-COOL
engine coolant. The coolant needs
to be replaced every 5 years or
240 000 km (150,000 mi), whichever
occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0253.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the

How to Add Coolant to the
Coolant Surge Tank
{Warning
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.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
{Warning
The electric fans under the hood
can start up even when the
engine is not running and can(Continued)
Warning (Continued)
cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
{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.

294 Vehicle Care
When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in aheated 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. See
Hazard
Warning Flashers 0159.
See If a Tire Goes Flat 0291 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 0298.
2. Unwrap the sealant/air hose (6) and the power plug (8).
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 (6)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (8) into the accessory power outlet in the

The pressure gauge (3) 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 (3). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure 0278.
The pressure gauge (3) 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.Caution
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
