10-22 Vehicle Care
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
located in the engine compartment
on the passenger side of the
vehicle. SeeEngine Compartment
Overview on page 10‑6.
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. Then 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. Then 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.

Vehicle Care 10-23
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 5‑35for 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:
Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches fire
because of being driven with no
coolant, the vehicle can be badly
damaged. The costly repairs
would not be covered by the
vehicle warranty.
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
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.

10-26 Vehicle Care
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 5‑45for more information.
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview on
page 10‑6 for reservoir location. Notice
.When using concentrated
washer fluid, follow the
manufacturer's 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.
Also, water does not clean as
well as washer fluid.
.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.
Brakes
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair.

11-4 Service and Maintenance
Engine Oil Change
When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system might not
indicate the need for vehicle service
for more than a year. The engine oil
and filter must be changed at least
once a year and the oil life system
must be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
SeeEngine Oil Life System on
page 10‑12.
Tire Rotation and Required
Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the
following services. See Tire
Rotation on page 10‑77.
.Check engine oil level and oil
life percentage. If needed,
change engine oil and filter, and
reset oil life system. See Engine
Oil on page 10‑10 andEngine
Oil Life System on page 10‑12.
.Check engine coolant level. See
Engine Coolant on page 10‑18.
.Check windshield washer fluid
level. See Washer Fluid on
page 10‑25.
.Visually inspect windshield wiper
blades for wear, cracking,
or contamination. See Exterior
Care on page 10‑110. Replace
worn or damaged wiper blades.
See Wiper Blade Replacement
