Caution (Continued)
operates. Any resulting
damage would not be
covered by the vehicle
warranty. See Add-On
Electrical Equipment0360.
To start the vehicle: 1. With the Keyless Access system, the remote key
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
warms up. Do not race the
engine immediately after
starting it.
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key is low, a Driver
Information Center (DIC)
message will display. See
Remote Key Operation 09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
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 hold it
there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow
the cranking motor to cool
down. When the engine
starts, let go of the button and 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.
Stop/Start System
This vehicle has a Stop/Start
system to shut off the engine
to help conserve fuel. It has
components designed for the
increased number of starts.
{Warning
The automatic engine Stop/
Start feature causes the
engine to shut off while the
vehicle is still on. Do not exit
the vehicle before shifting to
P (Park). The vehicle may
restart and move

Warning (Continued)
unexpectedly. Always shift
to P (Park), and then turn
the ignition off before
exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied
and the vehicle is at a
complete stop, the engine may
turn off. When stopped, the
tachometer displays AUTO
STOP. See Tachometer 0130.
When the brake pedal is
released or the accelerator
pedal is pressed, the engine
will restart.
To maintain vehicle
performance, other conditions
may cause the engine to
automatically restart before
the brake pedal is released.
Auto Stops may not occur
and/or auto restarts may
occur because:
.The climate control settings
require the engine to be
running to cool or heat the
vehicle interior.
.The vehicle battery needs to
charge.
.The vehicle battery has
recently been disconnected.
.Minimum vehicle speed has
not been reached since the
last Auto Stop.
.The accelerator pedal is
pressed.
.The engine or transmission
is not at the required
operating temperature.
.The outside temperature is
not in the required operating
range.
.The vehicle transmission is
shifted out of D (Drive) to
any gear other than P (Park).
.Certain driver modes have
been selected. See Driver
Mode Control 0278.
.The vehicle is on a steep hill
or grade.
.The driver door has been
opened or the driver seat
belt has been unbuckled.
.The hood has been opened.
.The Auto Stop has reached
the maximum allowed time.
Auto Stop Disable Switch
The automatic engine Stop/
Start feature can be disabled
and enabled by touching the
hsymbol. Auto Stop is
enabled each time you start
the vehicle.
