vehicle has:
.Enhanced high-speed control.
. Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak.
For vehicles with eLSD, driven
under severe conditions, the rear

Competitive Driving Mode 0205
and Maintenance Schedule 0307.Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with a manual
transmission, the cruise control will
remain active when the gears are
shifted. The cruise is disengaged if
the clutch is pressed for several
seconds. If the Traction Control System (TCS)
begins to limit wheel spin while you
are using cruise control, the cruise
control automatically disengages.
See
Traction Control/Electronic
Stability Control 0199. When road
conditions allow for using safely
again, cruise control can be turned
back on.
If the brakes are applied, cruise
control disengages.
1: Press to turn cruise control on
or off. A white indicator comes on in
the instrument cluster when cruise
is turned on.

1. Engine Oil Drain Plugs
2. Seals
Steps to follow:1. Remove the two engine oil drain plugs from the bottom of
the engine oil pan. One drain
plug drains the external oil tank
via the oil transfer supply line.
The other drain plug drains
residual oil from the crankcase
sump. Allow the oil to drain.
2. Once the oil has been drained from the engine, remove the
engine oil filter and allow the oil
to drain. 3. Reinstall both drain plugs and
tighten them to 25 Y
(18 lb ft).
4. Replace the oil filter and tighten it three-quarters to one
turn after gasket contact. See
Maintenance Replacement
Parts 0317 for the correct filter.
5. Oil is filled through the opening in the top of the external
engine oil tank. Remove the oil
fill cap.
6. Add oil to the oil tank. See Capacities and
Specifications 0321.
7. Install the oil fill cap and insert the dipstick, if removed.
8. Start the engine and let it run at idle for at least 15 seconds.
This will circulate the fresh
engine oil through the
lubrication system.
9. Shut off the engine and check the oil level as described under
“Checking Engine Oil (Z06,
Grand Sport, and Stingray
with Z51).”
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants 0316.
Specification
Ask for and use engine oils that
meet the dexos1™ specification.
Engine oils that have been
approved by GM as meeting the

Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the
automatic transmission fluid listed
in Recommended Fluids and
Lubricants 0316.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule 0307, and be sure to use
the fluid listed in Recommended
Fluids and Lubricants 0316.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon as possible. See
Recommended
Fluids and Lubricants 0316 for the
proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
The fluid will darken over time. See
Maintenance Schedule 0307 for
when to replace the fluid.
When to Check and What
to Use
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview
0 225 for reservoir location. Refer to
Recommended Fluids and
Lubricants 0316 for the proper fluid
to use. The fluid requires changing.
See Maintenance Schedule 0307.
How to Check and Add Fluid
Visually check the clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The hydraulic
clutch fluid system should be closed
and sealed.
Do not remove the cap to check the
fluid level or to top off the fluid level.
Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.

Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL®engine
coolant. See Recommended Fluids
and Lubricants 0316. The fluid
requires changing at certain
intervals. See Maintenance
Schedule 0307.
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 0244.
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 vehicle's coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine

Warning (Continued)
could get too hot but you would
not get the overheat warning. The
engine could catch fire and you or
others could be burned. Use a
mixture of 40% DEX-COOL
coolant and 60% clean, drinkable
water.
Use a mixture of 40% DEX-COOL
coolant and 60% clean, drinkable
water. If using this mixture, nothing
else needs to be added. This
mixture:
. Gives freezing protection down
to−28 °C (−18 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.

248 Vehicle Care
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light 0110.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid
at the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0307.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0316.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid.
Refer to the replacement number on
the original battery label when a
new battery is needed.
