.Check engine oil with every
refueling and add if necessary. Oil
and fuel consumption may be
higher than normal during the
first 2 400 km (1,500 mi).
. To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do not
have maximum traction and may
tend to slip.
. New brake linings also need a
break–in period. Avoid making
hard stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced.Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference to
the Keyless Access system. See Remote
Keyless Entry (RKE) System Operation
0 35.
To shift out of P (Park), the ignition
must be on or in ACC/ACCESSORY,
and the brake pedal must be applied. Stopping the Engine/OFF (No
Indicator Lights) :
When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0224.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition will turn off.
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.

DRIVING AND OPERATING 219
Move the shift lever to P (Park) or
N (Neutral). To restart the engine
when the vehicle 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 Equipment0295.
PLUG-IN Starting Procedure 1. With the Keyless Access system, the Remote Keyless Entry (RKE)
transmitter must be in the
vehicle. Press ENGINE START/ STOP with the brake pedal
applied. When the engine begins
cranking, let go of the button.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
battery is low, a Driver
Information Center (DIC) will
display a message. See
Remote
Keyless Entry (RKE) System
Operation 035.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. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you press ENGINE START/
STOP. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, release
the accelerator. If the vehicle
starts briefly but then stops
again, do the same thing. 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.
When the state of charge is low and
the hood is open, the vehicle may not
start. Close the hood and follow the
starting procedure again.
The vehicle will emit an audible
startup beep when the vehicle is ready
to be driven. When the vehicle ready
light is on in the instrument cluster,

two minutes.
. With the hood open, the engine
will be in an Auto Stop. The driver
may force the engine on when the
hood is open, by completely

276 DRIVING AND OPERATING
The vehicle has a Charging Status
Indicator (CSI) at the center of the
instrument panel near the windshield.
When the vehicle is plugged in and
the vehicle power is off, the CSI
indicates the following:
.Short Flashing Green –Vehicle is
plugged in. Battery is not fully
charged. Flash rate increases from
one to four flashes as battery
charges.
. Long Flashing Green –Vehicle is
plugged in. Battery is not fully
charged. Battery charging is
delayed.
. Solid Green –Vehicle is plugged
in. Battery is fully charged.
. Solid Yellow –Vehicle is plugged
in. It is normal for the CSI to turn
yellow for a few seconds after
plugging in a compatible charge
cord. The solid yellow may be
extended depending on the vehicle
and if there is a total utility
interruption via OnStar. See Utility
Interruption of Charging (PLUG-IN
Only) 0284. This may also indicate
that the charging system has
detected a fault and will not charge the battery. See
“Charge
Cord Status Indicators ”in Charge
Cord (PLUG-IN Only) 0279.
If the vehicle is plugged in and vehicle
power is on, the CSI will flash or will
be solid green, depending on the
charge level. This also happens during
a remote start if the vehicle is
plugged in.
If the vehicle is plugged in and the
CSI is off, a total utility interruption
using OnStar or a charging fault has
been detected. See Utility Interruption
of Charging (PLUG-IN Only) 0284 or
“Charge Cord Status Indicators ”in
Charge Cord (PLUG-IN Only) 0279.
A message displays if the vehicle is
not able to charge.
Following is the vehicle feedback
when the charge cord is plugged in.
