Ignition Modes
The keyless starting system has three
modes:
Off: Turns the ignition off.
• Without applying the brake pedal,
press and release the button once
when the ignition is in the on mode, or
when the engine is running but the
vehicle is not moving.
On:
All electrical circuits are operational
and the warning lamps and indicators
illuminate.
• Without applying the brake pedal,
press and release the button once.
Start:
Starts the engine.
• Press the brake pedal, and then press
the button for any length of time. An
indicator light on the button illuminates
when the ignition is on and when the
engine starts.
STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer. Note:
You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each
time, without the engine starting, you
reached the 60-second time limit. A
message appears in the information display
alerting you that you exceeded the cranking
time. You cannot attempt to start the
engine for at least 15 minutes. After 15
minutes, you are limited to a 15-second
engine cranking time. You need to wait 60
minutes before you can crank the engine for
60 seconds again.
Before starting your vehicle, check the
following:
• Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P).
• Switch the ignition on. For vehicles with
a keyless ignition, see the following
instructions.
Vehicles with an Ignition Key
Note: Do not touch the accelerator pedal.
1. Fully depress the brake pedal.
2. Turn the key to the start position to start the engine.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.
Vehicles with Keyless Start
Note: Do not touch the accelerator pedal.

3.
Press and hold the push button ignition
switch, or press it three times within
two seconds.
4. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING: If you smell exhaust
fumes inside your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. Carbon
monoxide is present in exhaust fumes.
Take precautions to avoid its dangerous
effects.
Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods, we
recommend that you do one of the
following:
• Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER
(If
Equipped) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal injury. WARNING:
Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block heater.
This could damage the power cable and
may cause an electrical short resulting in
fire, injury and property damage.
Note: The heater is most effective when
outdoor temperatures are below
0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.

•
Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the vehicle
from the engine and exhaust system heat
and noise. On vehicles with no original
equipment floor covering insulation, do not
carry passengers in a manner that permits
prolonged skin contact with the metal
floor. Failure to follow these instructions
may result in fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
