key is in the ignition. If the ignition
becomes difficult to turn, seeKeys
on page 2-1.
Starting the Engine
Place the transmission in the
proper gear.
{Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See Add-On Electrical Equipment
on page 9-61.
{Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage

Caution (Continued)
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle
when it is already moving, use
N (Neutral) only.
{Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal down to the
floor and start the engine. Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go down as the engine
warms. Do not race the engine
immediately after starting it.
Allow the oil to warm up and
lubricate all moving parts.
{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.
2. 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. Push the
accelerator pedal all the way to
the floor and hold it there as you
hold the key in START for a
maximum of 15 seconds. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool. When the engine starts,
let go of the key and accelerator.
If the vehicle starts briefly but
then stops again, repeat the
procedure. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below−18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above
−18°C (0°F).
Using the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is on the
passenger side of the engine
compartment, next to the engine
compartment fuse block for
V6 models.
Check the heater cord for
damage. If it is damaged, do not
use it. See your dealer for a
replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
.Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection

.Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension cord
in good operating condition,
or using a damaged heater or
extension cord, could make it
overheat and cause a fire,
property damage, electric
shock, and injury.
.Do not operate the vehicle
with the heater cord
permanently attached to the(Continued)

vehicle. Possible heater cord
and thermostat damage could
occur.
.While in use, do not let the
heater cord touch vehicle
parts or sharp edges. Never
close the hood on the
heater cord.
.Before starting the vehicle,
unplug the cord, reattach the
cover to the plug, and
securely fasten the cord.
Keep the cord away from any
moving parts.
4. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
If you do not it could be
damaged. The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.

Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire. (Continued)
Warning (Continued)
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park on
page 9-24. If you are towing a
trailer, see Driving Characteristics
and Towing Tips on page 9-56.
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking
brake set. Release the button and check that
the shift lever cannot be moved out
of P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see
“Shifting Into Park”
listed previously.
If torque lock does occur, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).

page 9-56.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Active Fuel Management®
Vehicles with V8 engines and an
automatic transmission, except ZL1,
have Active Fuel Management
®.
This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions.

7695163) - 2015 - crc - 9/4/14
Driving and Operating 9-27
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.Engine Exhaust
{Warning
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airflow or tail pipes).
.The exhaust smells or
sounds strange or different.
.The exhaust system leaks
due to corrosion or damage.
.The vehicle exhaust system
has been modified, damaged,
or improperly repaired.(Continued)
Warning (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.

The Driver Information Center (DIC)
displays the current gear selected in
the lower left corner. When Sport
Mode is active, an S is displayed.
If Manual Mode or Electronic Range
Select (ERS) Mode are active, an M
and the current gear selected (Tap
Shift) or the maximum gear allowed
(ERS Mode) are displayed next to
the M.
P (Park): This position locks the
rear wheels. It is the best position to
use when starting the engine
because the vehicle cannot move
easily.
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left

the vehicle warranty. Shift to
R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see If
the Vehicle Is Stuck on page 9-13.
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. Also, use
N (Neutral) when the vehicle is
being towed.
{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.
(Continued)
Warning (Continued)
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
{Caution
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. When the ZL1 is in
D (Drive), the first shift after start will
be from 1 (First) gear. Following
starts will begin in 2 (Second) gear.

9-30 Driving and Operating
If more power is needed for
passing, and the vehicle is:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Powertrain Braking (V6 and
V8 Engines Except ZL1)
When driving on steep descents
with the shift lever in D (Drive) or
M (Manual Mode) where frequent
braking is required, the transmission
will shift down a gear to help hold
vehicle speed and reduce brake
wear. If the driver continues to press
the brake, the transmission will
downshift until 3 (Third) gear is
reached.
If the brake is released for some
time, the transmission will upshift a
gear. If the road levels out and the
accelerator pedal is pressed, the
transmission will upshift until the
appropriate gear is reached.
{Caution
If the vehicle accelerates slowly,
or does not shift gears, the
transmission could be damaged.
Have the vehicle serviced
right away.
M (Manual Mode): This position
allows the driver to select gears
appropriate for current driving
conditions.
With the shift lever in M (Manual
Mode) position, vehicles with axle
code GW8 will enter ERS Mode.
See Manual Mode on page 9-31.
With the shift lever in M (Manual
Mode) position, and without using
the Tap Shift controls on the
steering wheel, vehicles with any
axle other than GW8 will be in Sport
Mode. Sport Mode provides firmer,
quicker shifting. The transmission
will shift automatically until the Tap
Shift controls are used. Tap Shift activates driver manual gear
selection. See
Manual Mode on
page 9-31.
V6 Models without Axle GW8, V8
Models Except ZL1
While driving in Sport Mode, if Tap
Shift has not been activated, the
transmission determines when the
vehicle is being driven in a
competitive manner. The
transmission may remain in a gear
longer than it would in the normal
driving mode based on throttle input
and vehicle lateral acceleration.
If there is a rapid reduction in
throttle from a heavy throttle
position, the transmission will
maintain the current gear up to near
redline rpm. While braking, the
transmission will automatically
downshift to the next lower gear
keeping engine speed above
approximately 3000 rpm. If the
vehicle is then driven for a short
time at a steady speed, and without
high cornering loads, the
transmission will up-shift one gear
at a time, until 6 (Sixth) gear. After

7695163) - 2015 - crc - 9/4/14
Driving and Operating 9-31
shifting to 6 (Sixth) gear, or coming
to a complete stop, the transmission
will return to normal Sport Mode
shifting.
ZL1
While driving in Sport Mode, if Tap
Shift has not been activated, the
transmission determines when the
vehicle is being driven in a
competitive manner, in a straight
line or while turning. The
transmission may remain in a gear
longer than it would in the normal
driving mode based on throttle input
and vehicle lateral acceleration.
If there is a rapid reduction in
throttle from a heavy throttle
position, the transmission will
maintain the current gear up to
approximately 4600 rpm. While
braking, the transmission will
automatically downshift to the next
lower gear keeping engine speed
below approximately 3000 rpm.
If the vehicle is then driven for a
short time at a steady speed, and
without high cornering loads, the
transmission will up-shift one gearat a time, until 6 (Sixth) gear. After
shifting to 6 (Sixth) gear, or coming
to a complete stop, the transmission
will return to normal sport mode
shifting.
If the vehicle detects aggressive
cornering, even without a heavy
application of the throttle, the
transmission will downshift and hold
a lower gear to near redline rpm, to
aid in vehicle handling balance and
to improve corner exit speeds.
Manual Mode
Electronic Range Select
(ERS) Mode
Vehicles with axle code GW8 have
an ERS Mode. ERS Mode allows
you to choose the top-gear limit of
the transmission with fully automatic
gear selection. This can help control
the vehicle's speed while driving
downhill or towing a trailer. The
vehicle has an electronic shift
position indicator within the
instrument cluster. When using the
ERS mode a number will display
next to the M, indicating the current
maximum gear allowed. Vehicles
with this feature have indicators on
the steering wheel. The controls are
on the back of the steering wheel.
To use this feature:
1. Move the shift lever to
M (Manual Mode).
2. Press the plus/minus paddles on the back of the steering wheel,
to increase or decrease the gear
range available.
When you shift from D (Drive) to
M (Manual Mode), the transmission
will shift to a lower gear range. The
highest gear available for this range
is displayed next to the M in the
DIC. The number displayed in the
DIC is the highest gear that the
transmission will be allowed to
operate in. This means that all
gears below that number are
available. For example, when
4 (Fourth) is shown next to the M,
1 (First) through 4 (Fourth) gears are
automatically shifted by the vehicle.
