208 Driving and Operating
.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 0194.
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.
See Competitive Driving Mode
0 205 andMaintenance
Schedule 0307.
Limited-Slip Differential
(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
