{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 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 tank pressure 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. Then keep turning the pressure cap slowly and
remove it.

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 ll bottle
is located in the engine compartment on the passenger
side of the vehicle. SeeEngine Compartment
Overview on page 5-14.
Check to see if coolant is visible in the coolant ll bottle.
If the coolant inside the coolant ll bottle is boiling, do not
do anything else until it cools down. If coolant is visible
but the coolant level is not at or above the COLD FILL
mark, add a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant at the coolant ll bottle, but be sure
the cooling system is cool before this is done.
If the engine is warm or hot, the coolant level should be
at or above the COLD FILL line on the side of the coolant
ll bottle. If the engine is cold, the coolant level should be
near the COLD FILL line on the side of the coolant ll
bottle. If it is not, you could have a leak in the cooling
system.
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.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. The vehicle
was designed and tested with top-quality brake parts.
When parts of the braking system are replaced — for
example, when the brake linings wear down and new
ones are installed — be sure to get new approved
replacement parts. If this is not done, the brakes might
not work properly. For example, if someone puts in brake
linings that are wrong for the vehicle, the balance
between the front and rear brakes can change — for the
worse. The braking performance expected can change in
many other ways if the wrong replacement brake parts
are installed.
Battery
This vehicle has a maintenance free battery. It is located
in the trunk, behind the trim panel, on the passenger side
of the vehicle. When it is time for a new battery, see your
dealer/retailer for one that has the replacement number
shown on the original battery’s label.Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
After a power loss, such as disconnecting the battery
or removing the maxi fuses in the power distribution
fuse block, the following steps must be performed
to calibrate the electronic throttle control. If this is
not done, the engine will not run properly.
1. Turn the ignition to ON/RUN. Do not start the
engine.
2. Leave the ignition in ON/RUN for at least three
minutes so that the electronic throttle control will
cycle and re-learn its home position.
3. Turn the ignition to LOCK/OFF.
4. Start and run the engine for at least 30 seconds.

7. Locate the vertical headlamp aiming screws, which
are under the hood near each headlamp assembly.
They are covered by a rubber caps.
The adjustment screw can be turned with a
6 mm hex driver.
8. Turn the vertical aiming screw until the headlamp
beam is aimed to the horizontal tape line. Turn it
clockwise or counterclockwise to raise or lower the
angle of the beam.
The top edge of the cut-off should be positioned at
the bottom edge of the horizontal tape line.9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal tape
line. The lamp on the left (A) shows the correct
headlamp aim. The lamp on the right (B) shows the
incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite
headlamp. Driver Side Shown

counterclockwise.
5. Pull the old bulb from the lamp housing keeping the
bulb straight as you pull it out.
6. Install a new bulb.
7. Reinstall the electrical connector by pushing in the
two plastic clips.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear or
cracking. SeeOwner Checks and Services on page 6-10.
It is a good idea to clean or replace the wiper blade
assembly on a regular basis or when worn. For proper
windshield wiper blade length and type, see
Maintenance Replacement Parts on page 6-16.
To replace the wiper blade assembly:
1. Turn the ignition to ON/RUN with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are in the out-wipe
position. The driver side blade will be straight up
and down on the windshield.
3. Pull the windshield wiper assembly away from the
windshield.
5-59

4. Lift up the wiper blade assembly cap.
5. Pull the wiper blade assembly down far enough to
release it from the J-hooked end of the wiper arm.
Slide the assembly away from the arm.
Allowing the wiper blade arm to touch the windshield
when no wiper blade is installed could damage
the windshield. Any damage that occurs would not
be covered by your warranty. Do not allow the
wiper blade arm to touch the windshield.
6. Replace the blade with a new one.7. Reinstall the wiper blade assembly by sliding it over
the wiper arm to engage the J-hooked end. Pull up
on the assembly to lock it into place.
8. Repeat the steps for the other wiper.
