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.
• If the block heater cord is under the
hood, Do Not remove the wiring from its
original location. Do Not close the hood
on the extension wiring.
• 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.

• If equipped with selectable drive modes
and when you select Normal, Conserve,
Slippery.
• The trailer is not connected.
• Tow haul mode not engaged.
• You have not selected Manual mode. The green Auto-Start-Stop
indicator light on the instrument
cluster will illuminates to indicate
when the automatic engine stop occurs. If the instrument cluster is
equipped with a grey
Auto-Start-Stop indicator light, it
illuminates when automatic engine stop is
not available due to one of the above noted
conditions not being met. Automatic Engine Restart
Any of the following conditions results in an
automatic restart of the engine:
•
You have removed your foot from the
brake pedal.
• You press the accelerator pedal.
• You press the accelerator and the brake
pedal at the same time.
• The driver seatbelt becomes unfastened
or the driver door is ajar.
• Your vehicle is moving.
• The interior compartment does not meet
customer comfort when air conditioning
or heat is on.
• Fogging of the windows could occur and
the air conditioning is on.
• The battery is not within optimal
operating conditions.
• You have exceeded the maximum engine
off time.
• When you press the Auto-Start-Stop
button with the engine automatically
stopped. •
The front defroster is turned to the Max
setting.
• When you shift into park (P) the engine
will restart.
Any of the following conditions may result in
an automatic restart of the engine:
• You have increased the blower fan speed
or changed the climate control
temperature.
• You have an electrical accessory turned
on or plugged in.
Note: You may notice that the climate seat
fan fluctuates during an automatic restart.

Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in size
(diameter or width), tread-type (All-Season
or All-Terrain) or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire label
or Safety Compliance label for limitations
when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note:
Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 in (15 cm)
above the bottom edge of
the rear bumper. Exceeding these limits may allow water to
enter vehicle components:
•
Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime the
rear axle has been submerged in water.
Water may have contaminated the rear axle
lubricant, which is not normally checked or
changed unless a leak is suspected or other
axle repair is required.
TOWING THE VEHICLE ON FOUR
WHEELS WARNING:
If your vehicle has a
steering wheel lock make sure the ignition
is in the accessory or on position when
being towed. Recreational Towing
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
See
Climate Control (page 165).
Follow these guidelines if you have a need
for recreational towing, such as towing your
vehicle behind a motorhome. These
guidelines are designed to prevent damage
to your transmission.
Two-wheel Drive Vehicles
You cannot tow a two-wheel drive vehicle
with any wheels on the ground as vehicle or
transmission damage may occur. You must
tow your vehicle with all four wheels off the
ground, for example when using a
car-hauling trailer.
Four-wheel Drive Vehicles Without
SLOW
CLIMB Mode
You cannot tow your vehicle with any wheels
on the ground or vehicle damage may occur.
You must tow your vehicle with all four
wheels off the ground, for example when
using a car-hauling trailer.

If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
Because your vehicle
’s engine is
electronically controlled by a computer, some
control conditions are maintained by power
from the battery. When the battery is
disconnected or a new battery is installed,
the engine must relearn its idle and fuel trim
strategy for optimum driveability and
performance. Flexible fuel vehicles (FFV)
must also relearn the ethanol content of the
fuel for optimum driveability and
performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle. 5. Run the engine until it reaches normal
operating temperature. While the engine
is warming up, complete the following:
Reset the clock. Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 118). Reset
the radio station presets. See Audio
System (page 460).
6. Allow the engine to idle for at least one minute.
7. Drive the vehicle at least 10 mi (16 km) to
completely relearn the idle trim and fuel
trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel trim
strategy.
Note: For flexible fuel vehicles, if you are
operating on E85, you may experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned. Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
If storing your vehicle for more than 30 days
without recharging the battery, we
recommend that you disconnect the negative
battery cable to maintain battery charge for
quick starting.
Battery Management System
(If Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery drain
is detected, the system temporarily disables
some electrical systems to protect the
battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
