Launch Control (Track
Mode Only)
A Launch Control feature is
available, within Competitive Driving
Mode, on all vehicles to allow the
driver to achieve high levels of
vehicle acceleration in a straight
line. Launch Control is a form of
traction control that manages tire
spin while launching the vehicle.
This feature is intended for use
during closed course race events
where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available
when the following criteria are met:
.Competitive Driving Mode is
selected or any of the
Performance Traction
Management modes are
selected. The TCS light comes
on the instrument cluster and the
appropriate DIC message
displays.
. The vehicle is not moving. .
The steering wheel is pointing
straight.
Manual Transmissions
. The clutch is pressed and the
vehicle is in 1 (First) gear.
. The accelerator pedal is rapidly
applied to wide open throttle.
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilize.
A smooth, quick release of the
clutch, while maintaining the fully
pressed accelerator pedal, will
manage wheel slip. Complete shifts
as described in Manual
Transmission 0192.
Automatic Transmissions
. The brake pedal must be firmly
pressed to the floor, equivalent
to a panic brake event.
. The accelerator pedal is rapidly
applied to wide open throttle. (If
the vehicle rolls due to wide
open throttle, release the
throttle, press the brake pedal more firmly, and re-apply the
accelerator to wide open
throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow
the engine rpm to stabilize.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode or Performance
Traction Management.
Competitive Driving Mode, PTM,
and Launch Control are systems
designed for a closed course race
track and not intended for use on
public roads. The systems are not
intended to compensate for lack of
driver experience or familiarity with
the race track.

Limited-Slip Differential
(Stingray without
Z51 Only)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard
axle most of the time, but when
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. For
vehicles with limited-slip differential,
driven under severe conditions, the
rear axle fluid should be changed.
SeeCompetitive Driving Mode
0 203 andMaintenance Schedule
0 312.
Limited-Slip Differential
(ZR1, Z06, Grand Sport,
and Stingray with Z51)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD
actively monitors vehicle sensors
and driver inputs to determine the
amount of change for the
conditions. With eLSD, the
vehicle has:
.
Enhanced high-speed control
. Improved traction through
corners, allowing more
acceleration
. More precise steering
. Increased vehicle agility
. Integration with StabiliTrak/ESC
For vehicles with eLSD, driven
under severe conditions, the rear
axle fluid should be changed.
See Competitive Driving Mode
0 203 andMaintenance Schedule
0 312.
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.

Once the vehicle reaches about
40 km/h (25 mph) or more, briefly
press RES/+. The vehicle returns to
the previous set speed.
Increasing Speed While Using
Cruise Control
Do one of the following:
.Press and hold RES/+ until the
desired speed is reached, then
release it.
. To increase vehicle speed in
small increments, briefly press
RES/+. For each press, the
vehicle goes about 1.6 km/h
(1 mph) faster.
Reducing Speed While Using
Cruise Control
Do one of the following:
. Press and hold SET/– until the
desired lower speed is reached,
then release it.
. To decrease the vehicle speed in
small increments, briefly press
SET/–. For each press, the
vehicle goes about 1.6 km/h
(1 mph) slower. Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previously set cruise speed.
While pressing the accelerator pedal
or shortly following the release to
override cruise control, briefly
pressing SET/–
will result in cruise
set to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
cruise control will disengage. Cruise Control in Manual Paddle
Shift Gear Selection
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive).
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.
If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver ’s gear selection is
active.
. If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an

special procedure when changing
the engine oil and filter. SeeEngine
Oil 0232.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system may not indicate that an oil
change is necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi) since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
Dry Sump Engine Break-In Oil
Change
If equipped with a dry sump engine,
the initial oil and filter change must
be performed at 800 km/500 mi.

service manual. To purchase a
service manual, seePublication
Ordering Information 0339.
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 correct
automatic transmission fluid. See
Recommended Fluids and
Lubricants 0321.
Change the fluid and filter at the
proper intervals. See Maintenance
Schedule 0312. Be sure to use the
correct fluid. See Recommended
Fluids and Lubricants 0321.
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 0321 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 0312 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 0321 for the proper fluid
to use. The fluid requires changing.
See Maintenance Schedule 0312.
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.

heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
The fluid level should be at or within
13 mm (0.5 in) of the bottom of the
fill plug hole threads. If it is at this
level, no additional fluid is needed.
If the fluid level is below 13 mm
(0.5 in), add fluid until it is above
this level.
What to Use
To add lubricant when the level is
low or to completely refill after
draining, seeRecommended Fluids
and Lubricants 0321. Then fill to
within 13 mm (0.5 in) of the bottom
of the fill plug hole threads with the
required lubricant.
Starter Switch Check
{Warning
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
