Driving and Operating 175
ON/RUN/START (Green Indicator Light) :This
mode is for driving and starting. With the
ignition off, and the brake pedal applied,
pressing ENGINE START/STOP once will place
the ignition system in ON/RUN/START.
Once engine cranking begins, release ENGINE
START/STOP. Engine cranking will continue
until the engine starts. See Starting the
Engine 0175.
The engine will then remain in ON/RUN.
Service 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 ENGINE
START/STOP for more than five seconds will
place the vehicle in Service Mode.
The instruments and audio system 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 Mode.
Press ENGINE START/STOP again to turn the
vehicle off.Starting the Engine
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.
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 0200.
Starting Procedure 1. With the Keyless Access system, the 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 transmitter battery is low, the Driver
Information Center (DIC) will display a
message. See
Driver Information Center
(DIC) 086 and
Remote Keyless Entry (RKE) System
Operation 07.
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 holding it there as you
hold 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.

2. Push the plastic hooks back to engagethe grille slats.
3. Repeat for all hooks to fully engage cover to grille.
4. Make sure all clips remain engaged during installation. The cover should be
stretched to a tight fit when properly
installed.
Engine Heater
Vehicles may have an engine heater. The
engine heater 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 heater at least
four hours before starting the vehicle. An internal thermostat in the plug end of the
cord will prevent engine heater operation at
temperatures above
−18 °C (0 °F).
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.
To Use the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is in the driver side of the
engine compartment, near the battery.
It is shipped from the factory with a tie
holding it in place. Use care in removing
the tie so that the cord is not damaged.
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
function. An ungrounded outlet could
cause an electric shock.
.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

pressing the button on the shift lever. If you
can, it means that the shift lever was not
fully locked into P (Park).
Torque Lock
If you are parking on a hill and do not shift
the transmission into P (Park) properly, the
weight of the vehicle may put too much
force on the parking pawl in the
transmission. You may find it difficult to pull
the shift lever out of P (Park). This is called
torque lock. To prevent torque lock, set the
parking brake and then shift into P (Park)
properly before you leave the driver seat. To
find out how, see“Shifting Into Park”
previously in this section.
When you are ready to drive, move the
shift lever out of P (Park) before releasing
the parking brake.
If torque lock does occur, you may need to
have another vehicle push yours a little
uphill to take some of the pressure from the
parking pawl in the transmission, so you can
pull the shift lever out of P (Park).
Shifting out of Park
This vehicle is equipped with a shift lock
control. The shift lock control is designed to
prevent movement of the shift lever out of
P (Park) unless the ignition is on and the
brake pedal is applied.
The shift lock control 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
- North America 0253.
To shift out of P (Park): 1. Apply the brake pedal.
2. Turn the ignition on.
3. Press the shift lever button.
4. Move the shift lever to the desired position.
If still unable to shift out of P (Park): 1. Fully release the shift lever button.
2. Hold the brake pedal down and press the shift lever button again.
3. Move the shift lever to the desired position. If the shift lever still cannot be moved from
P (Park), see
“Shift Lock Manual Release”
following.
Shift Lock Manual Release
The automatic transmission has an electric
park lock. The ignition must be on and the
brake pedal must be pressed so the shift
lever can be moved from the P (Park)
position. If the battery has lost power, the
shift lever cannot be moved from P (Park)
unless the shift lock manual release is
disengaged manually.
To access the shift lock manual release:
1. Turn the ignition off.
2. Hold the brake pedal down. Apply the parking brake.

Filling a Portable Fuel Container
{Warning
Never fill a portable fuel container while
it is in the vehicle. Static electricity
discharge from the container can ignite
the fuel vapor. You or others could be
badly burned and the vehicle could be
damaged. To help avoid injury to you
and others:
.Dispense fuel only into approved
containers.
.Do not fill a container while it is
inside a vehicle, in a vehicle's trunk, in
a pickup bed, or on any surface other
than the ground.
.Bring the fill nozzle in contact with
the inside of the fill opening before
operating the nozzle. Maintain contact
until filling is complete.
.Keep sparks, flames, and smoking
materials away from fuel.
.Avoid using electronic devices while
pumping fuel.
Trailer Towing
General Towing Information
{Warning
Never tow a trailer with your vehicle.
It was not designed or intended to tow a
trailer.
Conversions and Add-Ons
Add-On Electrical Equipment
{Warning
The Data Link Connector (DLC) is used for
vehicle service and Emission Inspection/
Maintenance testing. SeeMalfunction
Indicator Lamp (Check Engine Light) 081.
A device connected to the DLC —such as
an aftermarket fleet or driver-behavior
tracking device —may interfere with
vehicle systems. This could affect vehicle
operation and cause a crash. Such devices
may also access information stored in the
vehicle’s systems.
Caution
Some electrical equipment can damage
the vehicle or cause components to not
work and would not be covered by the
vehicle warranty. Always check with your
dealer before adding electrical equipment.
Add-on equipment can drain the vehicle's
12-volt battery, even if the vehicle is not
operating.
The vehicle has an airbag system. Before
attempting to add anything electrical to the
vehicle, see Servicing the Airbag-Equipped
Vehicle 047 and
Adding Equipment to the Airbag-Equipped
Vehicle 047.
