Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering.
. New brake linings also need a
break-in period. Avoid making
hard stops. This is
recommended every time brake
linings are replaced.
For the first 800 km (500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 rpm. .
Avoid driving at any one
constant speed, fast or slow,
including the use of cruise
control.
. Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
. Do not let the engine labor.
Never lug the engine. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
. If equipped with a dry sump
engine (Stingray with Z51,
Grand Sport, and Z06), the initial
oil and filter change must be
performed at 800 km (500 mi).
For the first 2 414 km (1,500 mi):
. Do not participate in track
events, sport driving schools,
or similar activities.
. Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal.
Front Air Dam
If equipped, the front air dam has
minimal ground clearance.
Under normal operation, the
components will occasionally
contact some road surfaces (speed
bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a
scraping noise. This is normal and
does not indicate a problem.
Use care when approaching bumps
or objects on road surfaces and
avoid them when possible.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials.
Dealer-installed accessories may
also contain composite materials.
These parts and accessories may
include the splitter or rocker
extensions.

Driving and Operating 181
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric Parking Brake 0195.{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/
STOP for longer than two seconds,
or press twice within five seconds.
ACC/ACCESSORY (Amber
Indicator Light) : This mode allows
the use of some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to off after
five minutes to prevent battery
rundown. ON/RUN/START (Green Indicator
Light) :
This mode is for driving and
starting. With the ignition off, and
the brake pedal applied, pressing
the button once will place the
ignition system in ON/RUN/START.
Once engine cranking begins,
release the button. Engine cranking
will continue until the engine starts.
See Starting the Engine 0182. The
ignition will then remain in ON/RUN.
Service Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off, and
the brake pedal not applied,
pressing and holding ENGINE
START/STOP for more than
five seconds will place the vehicle in
Service Mode. The instruments and
audio systems will operate as they
do in ON/RUN, but the vehicle will
not be able to be driven. The engine

4. If the engine does not start andno DIC message is displayed,
wait 15 seconds before trying
again to let the cranking motor
cool down.
If the engine does not start
after five to 10 seconds,
especially in very cold weather
(below −18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor while cranking for up
to 15 seconds maximum. Wait
at least 15 seconds between
each try, to allow the cranking
motor to cool down. When the
engine starts, let go of the
accelerator. If the vehicle starts
briefly but then stops again,
repeat these steps. This clears
the extra gasoline from the
engine.Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever to
P (Park) and press and hold
ENGINE START/STOP on the
instrument panel, until the engine
shuts off. If the shift lever is not in
P (Park), the engine shuts off and
the vehicle goes into the accessory
mode. The DIC displays SHIFT TO
PARK. Once the shift lever is moved
to P (Park), the vehicle turns off.
If the vehicle has a manual
transmission, move the shift lever to
R (Reverse) and set the parking brake after turning off the engine by
pressing and holding ENGINE
START/STOP.
If the RKE transmitter is not
detected inside the vehicle when it
is turned off, the DIC displays a
message.

or other things that can burn.
Active Fuel Management
(Except ZR1/LT5)
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual
transmission, the system is only
active in Eco Mode. With an
automatic transmission, the system
is available in all modes, but is more
aggressive in Eco Mode. See Driver
Mode Control 0200.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the

Driving and Operating 189
Downshifting the transmission in
slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0161.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0189.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.
M : In M (Manual Mode), the
transmission can be shifted like a
manual transmission using the
paddle shift controls. See Manual
Mode 0189.
Manual Mode
Manual Paddle Shift
(Automatic Transmission)
When the shift lever is moved to
M (Manual Mode), the transmission
enters Manual Mode. The
transmission will hold the current
gear until a change is requested.
The paddles on the steering wheel
can be used to manually upshift or
downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts.
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster
or the Head-Up Display (HUD),
if equipped. See Head-Up Display
(HUD) 0123.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) gear allows
the vehicle to gain more traction.
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from M (Manual Mode)
back to D (Drive).

190 Driving and Operating
When the shift lever is in D (Drive),
press either the right (+) plus paddle
or the left (−) minus paddle to place
the transmission in Temporary
Manual Paddle Shift mode. The
gear indicator next to the shift lever,
in the cluster, and in the HUD will
display an M, even though the shift
lever is still in D (Drive). To exit the
system, hold the (+) plus paddle for
more than one second. The system
will return to automatic shifting after
six seconds of cruising at a steady
speed, no manual shifts, no
aggressive cornering, or when the
vehicle comes to a stop.
While the Manual Paddle Shift gear
selection system is active, the
transmission will automatically
downshift through the gears as thevehicle slows. The transmission will
select 1 (First) gear as the vehicle
stops. From a stop, the vehicle will
start from and hold 1 (First) gear
unless the manual paddle shifts are
used to shift into a different gear,
or D (Drive) is selected.
If the left (−) minus paddle is held
down briefly, the transmission will
downshift to the lowest gear
possible for the vehicle speed. If the
paddle continues to be held as the
vehicle slows, downshifts will
continue to occur as vehicle speed
allows. This feature also works
while in Temporary Manual Paddle
Shift mode, but first press and
release the (−) minus paddle to
enter Temporary Manual Paddle
Shift mode, then press and hold the
(−) minus paddle briefly.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
the vehicle speed is too fast or too
slow, nor will it allow a start from
3 (Third) or higher gear.
If upshifting does not occur when
needed, vehicle speed will be
limited to protect the engine.When a requested shift is denied
due to the speed restrictions shown,
a DIC message will be displayed,
and the current gear remains
displayed in the instrument cluster
and HUD.
Manual Paddle Shift operation is
available for use with cruise control.
See
Cruise Control 0207.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
For Vehicles with a 2.41:1 Axle
Ratio (RPO GXB)
. Upshifts to 3 (Third) gear require
approximately 25 km/h (16 mph).
. Upshifts to 4 (Fourth) gear
require approximately 37 km/h
(23 mph).
. Upshifts to 5 (Fifth) gear require
approximately 48 km/h (30 mph).
. Upshifts to 6 (Sixth) gear require
approximately 60 km/h (37 mph).
