196 DRIVING AND OPERATING
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice in five seconds.
ACC/ACCESSORY (Amber Indicator
Light) :This mode allows you to use
some electrical accessories when the
engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after five minutes
to prevent battery rundown.
ON/RUN/START (Green Indicator
Light) : This mode is for driving and
starting. With the ignition off, and the
brake pedal applied, pressing the
button once will place the ignition
system in ON/RUN/START. Once
engine cranking begins, release the
button. Engine cranking will continue
until the engine starts. See Starting the
Engine 0196. The ignition will then
remain in ON/RUN. Service Only Mode
This power mode is available for
service and diagnostics, and to verify
the proper operation of the
malfunction indicator lamp as may be
required for emission inspection
purposes. With the vehicle off, and the
brake pedal not applied, pressing and
holding the button for more than
five seconds will place the vehicle in
Service Only Mode. The instruments
and audio systems will operate as they
do in ON/RUN, but the vehicle will
not be able to be driven. The engine
will not start in Service Only Mode.
Press the button again to turn the
vehicle off.
Starting the Engine
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 Equipment
0243.
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.

DRIVING AND OPERATING 197
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)
message will display. SeeKey and
Lock Messages 0145 and Remote
Keyless Entry (RKE) System
Operation 029.
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 °Cor 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.
Stop/Start System
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause the
vehicle to move. You or others may
be injured. Because the vehicle has
the auto engine stop/start feature,
(Continued)
Warning (Continued)
the vehicle's engine might seem to
be shut off; however, once the brake
pedal is released, the engine will
start up again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before exiting
the vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine
and help conserve fuel.
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 may point to AUTO
STOP, or the Auto Stop light may
come on in the instrument cluster. See
Tachometer 0121 and Auto Stop Mode
(Uplevel Cluster) 0134. When the
brake pedal is released or the
accelerator pedal is pressed, the
engine may restart.
