9-18 Driving and Operating
A warning tone sounds when the
driver door is opened if the ignition
is still in ACC/ACCESSORY and the
key is in the ignition.
If the ignition becomes difficult to
turn, seeKeys on page 2-1.
Key Lock Release
Vehicles with an automatic
transmission and a key start
system, are equipped with an
electronic key lock release. The key
lock release is designed to prevent
ignition key removal unless the shift
lever is in P (Park). The key lock release is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. If the vehicle has an
uncharged battery or a battery with
low voltage, try charging or jump
starting the battery. See
Jump
Starting on page 10-69.
If charging or jump starting the
battery does not work, locate the
hole below the ignition lock. Insert a
flat bladed tool or another key from
the key chain into the opening.
When the lever can be felt, actuate
the lever toward the driver, and
remove the key from the ignition.
Starting the Engine
Place the transmission in the
proper gear.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. 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.
{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 9-57.
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. The
vehicle will not start if the clutch
pedal is not all the way down.

Driving and Operating 9-19
Starting Procedure (Key Access)
1. With your foot off the acceleratorpedal, 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.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START for many seconds,
cranking stops after 15 seconds
to prevent cranking motor
damage. To prevent gear
damage, this system also
prevents cranking if the engine is already running. Engine
cranking can be stopped by
turning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.
{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.
Starting Procedure (Keyless
Access)
1. If the vehicle has the Keyless Access system, the Remote
Keyless Entry (RKE) transmitter
must be in the vehicle. Put your
foot on the brake pedal and
press the ENGINE START/
STOP button. When the engine
begins cranking, let go of the
button.

Driving and Operating 9-23
Shifting out of Park
Automatic Transmission
Shift Lock
The vehicle has an automatic
transmission shift lock control
system. The shift lock control
system is designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park).
.Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN and the
brake pedal is applied.
The shift lock is always functional
except in the case of an uncharged
or low voltage (less than 9‐volt)
battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See Jump Starting on
page 10-69. If the shift lever cannot be moved
out of P (Park):
1. Apply and maintain the regular
brakes.
2. Turn the ignition to the ON/RUN position. See Ignition Positions
(Keyless Access) on page 9-14
or Ignition Positions (Key
Access) on page 9-16 for more
information.
3. Let up on the shift lever and make sure the shift lever is
pushed all the way into P (Park).
4. Press the shift lever button.
5. Move the shift lever into the desired gear.
If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
Parking
If the vehicle has a manual
transmission, before getting out of
the vehicle, move the shift lever into R (Reverse) if parking on a downhill
slope. On a level surface or an
uphill slope, use 1 (First) gear.
Firmly apply the parking brake. Turn
the wheels toward the curb for a
downhill slope, or away from the
curb for an uphill slope. Once the
shift lever has been placed into gear
with the clutch pedal pressed in,
turn the ignition key to LOCK/OFF,
remove the key, and release the
clutch.
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.

Automatic
Transmission
The selected gear is also shown in
the instrument cluster.
P (Park):This position locks the
drive 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.
(Continued)
Warning (Continued)
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 9-22 andDriving
Characteristics and Towing Tips
on page 9-52.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. The regular brake must be
fully applied first and then the shift
lever button pressed before shifting
from P (Park) when the ignition key
is in ON/RUN. If you cannot shift out
of P (Park), ease pressure on the
shift lever, then push the shift lever

9-30 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5-18. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.

Driving and Operating 9-31
Parking Brake
The Electric Parking Brake (EPB)
switch is on the center console. The
EPB can always be activated, even
if the ignition is off. To prevent
draining the battery, avoid repeated
cycles of the EPB when the engine
is not running.
The system has a red parking brake
status light and an amber parking
brake warning light. SeeElectric
Parking Brake Light on page 5-17.
There are also parking brake-related
Driver Information Center (DIC) messages. See
Brake System
Messages on page 5-26. In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a
complete stop.
2. Lift up the EPB switch momentarily.
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red parking brake status light is flashing.
See your dealer. See
Electric
Parking Brake Light on page 5-17.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.

9-32 Driving and Operating
EPB Release
To release the EPB:
1. Place the ignition in the ACC/ACCESSORY or ON/RUN
position.
2. Apply and hold the brake pedal.
3. Push down momentarily on the EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.{Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
The EPB can also be used to
prevent roll back for vehicles with a
manual transmission taking off on a
hill. When no roll back is desired, an
applied EPB will allow both feet to be used for the clutch and
accelerator pedals in preparation for
starting the vehicle moving in the
intended direction. In this case,
there is no need to push the switch
to release the EPB.
If parking on a hill, or if the vehicle
is pulling a trailer, see
Driving
Characteristics and Towing Tips on
page 9-52.
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The

6042574) - 2014 - crc - 10/18/13
Driving and Operating 9-33
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates The
Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade (less than 10%). This feature
is designed to prevent the vehicle
from rolling, either forward or
rearward, during vehicle drive off.After the driver completely stops
and holds the vehicle in a complete
standstill on a grade, HSA will be
automatically activated and the DIC
will display the HILL START ASSIST
ACTIVE message. During the
transition period between when the
driver releases the brake pedal and
starts to accelerate to drive off on a
grade, HSA holds the braking
pressure to ensure that there is no
rolling. The brakes will automatically
release after three seconds or when
the accelerator pedal is applied
within the three-second window.
A pop noise might be heard when
the brakes release. This is normal.
It will not activate if the vehicle is in
a drive gear and facing downhill or if
the vehicle is facing uphill and in
R (Reverse).
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel slip
and assist the driver in maintaining
control, especially on slippery road
conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power 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 the

6042574) - 2014 - crc - 10/18/13
9-34 Driving and Operating
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
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.
SeeIf the Vehicle Is Stuck on
page 9-9 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.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.

Cruise Control
The cruise control lets the vehicle
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use the
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.
The vehicle has a Traction Control
System (TCS) or StabiliTrak system
that begins to limit wheel spin while
using cruise control and the cruise
