2006 CADILLAC CTS clutch

How to Add Manual Transmission Fluid
Here is how to add uid. SeeRecommended Fluids
and Lubricants on page 6-13to determine which type of
uid to use.
1. Remove the ller plug.
2. Add uid at the ller plug hole. Add only enough
uid to bring the uid level up to the bottom of the
ller plug hole.
3. If your vehicle is a CTS, replace the gasket and
reinstall the ller plug. If your vehicle is a CTS-V,
apply LOCTITE
®#516 or equivalent sealant to
the threads and then reinstall the ller plug.
Again, with either vehicle, be sure the plug is
fully seated.
Hydraulic Clutch
It is not necessary to regularly check clutch uid
unless you suspect there is a leak in the system.
Adding uid will not correct a leak.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
The hydraulic clutch uid
reservoir cap has this
symbol on it. SeeEngine
Compartment Overview
on page 5-12for reservoir
location.
Refer to the Maintenance Schedule to determine how
often you should check the uid level in your clutch
master cylinder reservoir and for the proper uid to use.
SeeOwner Checks and Services on page 6-9and
Recommended Fluids and Lubricants on page 6-13.
How to Check and Add Fluid
Make sure the uid level is at the MIN (Minimum)
line on the side of the reservoir. If it is not, remove
the cap and add the proper uid until the level reaches
the MIN line.

At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-33.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine in each gear. The vehicle should start only in
PARK (P) or NEUTRAL (N). If the vehicle starts in
any other position, contact your GM Goodwrench
®
dealer for service.
On manual transmission vehicles, put the shift lever
in NEUTRAL, push the clutch pedal down halfway,
and try to start the engine. The vehicle should start
only when the clutch pedal is pushed down all the
way to the oor. If the vehicle starts when the clutch
pedal is not pushed all the way down, contact your
GM Goodwrench
®dealer for service.
Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-33.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the ignition to ON, but do
not start the engine. Without applying the regular
brake, try to move the shift lever out of PARK (P)
with normal effort. If the shift lever moves out
of PARK (P), contact your GM Goodwrench
®dealer
for service.
