Vehicle Care 10-19
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant surge tank.
If no coolant is visible in the surge
tank, add coolant as follows:
1. Remove the coolant surge tankpressure cap when the cooling
system, including the coolant
surge tank pressure cap and
upper radiator hose, is no longer
hot. Turn the pressure cap
slowly counterclockwise about
one-quarter turn and then stop.
If you hear a hiss, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure capslowly and remove it.
3. Fill the coolant surge tank withthe proper mixture, to slightly
above the FROID/FULL COLD
line on the side of the coolant
surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. The upper radiator
hose is the top hose coming out
of the radiator, on the passenger
side of the vehicle. Watch out for
the engine cooling fans.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge tank
until the level reaches the
FROID/FULL COLD line on the
side of the coolant surge tank.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.

10-20 Vehicle Care
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.
Recheck the coolant level in the
bottle next time you use your
vehicle to ensure the system is full
when cold.
Checking Coolant in the
Intercooler System (CTS-V)
The vehicle must be on a level
surface when checking the coolant
level.
The super charged engine
intercooler coolant fill neck is in the
engine compartment on the
passenger side of the vehicle. See
Engine Compartment Overview on
page 10‑5.
On the coolant fill neck, there is a
cold fill region between the two
horizontal lines shown.
Check to see if coolant is visible in
the coolant fill neck. If the coolant is
not visible or below the cold fill region in the fill neck, add a 50/
50 mixture of clean, drinkable water
and DEX-COOL coolant at the
coolant fill bottle, but be sure the
cooling system is cool before this
is done.
Adding Coolant to the
Intercooler System
Coolant (CTS-V)
1. Remove the intercooler system
pressure cap when the
intercooler system hoses are no
longer hot. Turn the pressure
cap slowly counterclockwise about one-quarter of a turn.
If you hear a hiss, wait for that to
stop. This allows any pressure
still left to be vented.
2. Keep turning the pressure cap slowly and remove it.
3. Add the proper DEX-COOL coolant mixture to the fill neck
until the coolant is within the
cold fill region.
With the intercooler system
pressure cap off, start the
engine and let it run for a couple
of minutes. Then turn the engine
off. By this time, the coolant
level inside the fill neck may be
lower. If the level drops where
coolant is no longer within the
cold fill region of the fill neck
with the engine off, add more of
the DEX-COOL coolant mixture
to the fill neck until the level is
again visible in the cold fill
region.
4. Replace the pressure cap tightly.

Vehicle Care 10-21
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.
If the coolant is not at the proper
level when the system cools down
again, see your dealer.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There are two engine hot messages
that may be displayed in the Driver
Information Center (DIC). See
Engine Cooling System Messages
on page 5‑34 for more information.
You may decide not to lift the hood
when one of these warnings appear,
but get service help right away. See
Roadside Service (U.S. and
Canada) on page 13‑7 orRoadside
Service (Mexico) on page 13‑9.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface. Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:
Running the engine
without coolant may cause
damage or a fire. Vehicle damage
would not be covered by the
warranty. See Overheated Engine
Protection Operating Mode on
page 10‑22 for information on
driving to a safe place in an
emergency.
If Steam Is Coming from the
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
(Continued)
WARNING (Continued)
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.

Vehicle Care 10-23
2. Wipe the cap and the top of thereservoir clean.
3. Unscrew the cap and wipe the dipstick with a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level on the dipstick.
The level should be between the
HOT and COLD marks. If necessary,
add only enough fluid to bring the
level between the marks.
What to Use
To determine what kind of fluid to
use, see Recommended Fluids and
Lubricants on page 11‑13. Always
use the proper fluid.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If you will be operating your vehicle in an area where the
temperature may fall below freezing,
use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
The WASHER FLUID LOW ADD
FLUID message will appear on the
Driver Information Center (DIC)
when the fluid level is low. See
Washer Fluid Messages on
page 5‑45.
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See
Engine
Compartment Overview on
page 10‑5 for reservoir location. Notice
.When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
to freeze and damage the
washer fluid tank and other
parts of the washer system.
.Fill the washer fluid tank only
three-quarters full when it is
very cold. This allows for
fluid expansion if freezing
occurs, which could damage
the tank if it is
completely full.
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
