wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0257.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.
Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills;
something could be in your lane
(e.g., stalled car, accident).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.

172 Driving and Operating
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0196.
. The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner
than when on dry pavement.
See Antilock Brake System
(ABS) 0193. .
Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0325. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set

Warning (Continued)
.Put things in the rear
area of your vehicle. Try
to spread the weight
evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in your vehicle.
.When you carry
something inside the
vehicle, secure it
whenever you can.
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.

188 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 0205.
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).

196 Driving and Operating
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak
system. These systems help limit
wheel spin and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, TCS applies
the brakes to the spinning wheel
and reduces engine power (by
closing the throttle and managing
engine spark) to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See
Cruise Control 0205.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See If the Vehicle Is Stuck 0173
and “Turning the Systems Off and
On” later in this section.The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin
. Flash when StabiliTrak is
activated
. Turn on and stay on when either
system is not working
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.

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
0 201 andMaintenance Schedule
0 304.
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
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
For vehicles with eLSD, driven
under severe conditions, the rear
axle fluid should be changed.
See Competitive Driving Mode
0 201 andMaintenance Schedule
0 304.
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.
