N (Neutral) :In this position, the engine does not
connect with the wheels. To restart the engine when
the vehicle is already moving, use N (Neutral) only.
If the vehicle needs towing, see Towing Your Vehicle
on
page 5‑33.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice: Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle. D (Drive) :
This position is for normal driving. It provides
the best fuel economy. If you need more power for
passing, push the pedal down to achieve the desired
level of acceleration.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
under Loss of Control on page 5‑18.
S (Sport Mode) : When in S (Sport Mode), the
transmission will work as an automatic until you use
the Manual Paddle Shift Controls, which activates driver
manual gear selection. See Manual Paddle Shift later in
this section. While in S (Sport Mode), the transmission
will have more noticeable upshifts for sportier vehicle
performance.

Shift Speeds (Manual Transmission)
{WARNING:
If you skip a gear when you downshift, you could
lose control of the vehicle. You could injure
yourself or others. Do not shift down more than
one gear at a time when you downshift.
This chart shows when to shift to the next higher gear
for the best fuel economy.
Manual Transmission Recommended Shift Speeds in mph (km/h)
Engine Acceleration Shift Speed
1 to 2 2 to 3 3 to 4 4 to 5 5 to 6
All
Engines 15 (24) 25 (40) 40 (64) 45 (72) 50 (80)
If the engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two or
more gears to keep the engine running smoothly or for
good engine performance.
Notice:
When shifting gears, do not move the shift
lever around unnecessarily. This may damage the
transmission. Shift directly into the next gear.

Battery Run-Down Protection
This vehicle has a feature to help prevent the battery
from being drained in case any of the following lamps
are left on; the underhood lamp, if your vehicle has
this feature, vanity mirror lamps, cargo lamps, reading
lamps, console or glove box lamps. If any of these
lamps are left on, they will automatically time-out after
about 10 minutes. To reset it, all of the above lamps
must be turned off or the ignition key on.
Head-Up Display (HUD)
{WARNING:
If the HUD image is too bright, or too high in your
field of view, it may take you more time to see
things you need to see when it is dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
For vehicles with the Head-Up Display (HUD), you can
see some of the driver information that appears on the
instrument panel cluster. The information may be displayed in English or metric
units and appears as an image focused out toward the
front of the vehicle. The HUD consists of the following
information:
.Speedometer
.Turn Signal Indicators
.High-Beam Indicator Symbol
.Tachometer
.Manual Paddle Shift Gear Indicator (If Equipped)
These displays on the HUD are for use when
using the manual paddle shift controls to shift
the transmission. See
“Manual Paddle Shift”in
Automatic Transmission Operation on page 3‑26.
.Shift Light
This light is used for performance driving to
indicate that the vehicle's best performance level
has been reached to shift the transmission into the
next higher gear. An arrow pointing up will light up
on the display just prior to reaching the engine fuel
cut-off mode. This cut-off is about 6,500 RPM for
the LS3 engine, 6,600 RPM for the LS9 & ZR1
engines and 7,000 RPM for the LS7 engine.
.Check Gauges Warning
.Engine Coolant Temperature Gauge
4-16

You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following: 1. Select
Hmode.
2. Press
?.
3. Select the a/c on.
4. Select the coolest temperature.
5. Select the highest fan speed. Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in the
vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
?
(Recirculation) : Press to turn the recirculation
mode on or off. An indicator light comes on to show
that recirculation is on. This mode prevents outside air
from entering your vehicle. It can be used to prevent
outside air and odors from entering your vehicle and
to help cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.

Speedometer and Odometer
The speedometer shows the speed in either kilometers
per hour (km/h) or miles per hour (mph). For more
information see “Personal Options” underDIC Vehicle
Personalization on page 4‑71.
To read the odometer with the ignition off, turn on the
parking lamps.
If the vehicle needs a new odometer installed, the
mileage total of the new odometer will be set to the
original kilometers (miles) of the old odometer. See your
dealer/retailer if the odometer must be replaced in the
vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Notice: Fuel shuts off at about 6500 rpm for
the base model, 7000 rpm for the Z06 model, and
6600 rpm for the ZR1 model. If the vehicle continues
to be driven at the fuel shut off rpm, the engine
could be damaged. Be sure to operate the vehicle
below the fuel shut off rpm or reduce the vehicle's
rpm quickly when the fuel shuts off.
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor
the light comes on.

One-to-Four Shift Light
(Manual Transmission)
When this light comes on,
the vehicle can only be
shifted from 1 (First) to
4 (Fourth) instead of
1 (First) to 2 (Second).
The shift must be completed into 4 (Fourth) to turn off
this feature. This helps the vehicle get the best possible
fuel economy.
After shifting to 4 (Fourth), the vehicle can be
downshifted to a lower gear.
Notice: Forcing the shift lever into any gear except
4 (Fourth) when the 1 TO 4 SHIFT light comes on
may damage the transmission. Shift only from
1 (First) to 4 (Fourth) when the light comes on. This light comes on when:
.The engine coolant temperature is higher
than 169°F (76°C),
.The vehicle is going 15 to 19 mph
(24 to 31 km/h) and
.The vehicle 21 percent throttle or less.
Brake System Warning Light
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking both parts
need to be working well.
