HEATED SEATS (If Equipped)
Front Seats WARNING
People who are unable to feel pain
to their skin because of advanced
age, chronic illness, diabetes, spinal
cord injury, medication, alcohol use,
exhaustion or other physical conditions,
must exercise care when using the heated
seat. The heated seat may cause burns
even at low temperatures, especially if
used for long periods of time. Do not place
anything on the seat that insulates against
heat, such as a blanket or cushion. This
may cause the heated seat to overheat.
Do not puncture the seat with pins, needles
or other pointed objects. This may damage
the heating element which may cause the
heated seat to overheat. An overheated
seat may cause serious personal injury. Do not do the following:
•
Place heavy objects on the seat.
• Operate the heated seat if water or any
other liquid spills on the seat. Allow the
seat to dry thoroughly.
Note: You must switch the ignition on to
use this feature. Press the heated seat symbol to cycle
through the various heat settings and off.
More indicator lights indicate warmer
settings.

Stopping the Engine When Your
Vehicle is Moving
WARNING
Switching off the engine when the
vehicle is still moving will result in a
loss of brake and steering assistance.
The steering will not lock, but higher effort
will be required. When the ignition is
switched off, some electrical circuits,
including air bags, warning lamps and
indicators may also be off. If the ignition
was turned off accidentally, you can shift
into neutral (N) and re-start the engine. Vehicles with an Ignition Key
1.
Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. When your vehicle has stopped, shift into park (P) and switch the ignition
off.
3. Apply the parking brake.
Vehicles with Keyless Start
1. Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. When your vehicle has stopped, shift into park (P).
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) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. 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.

Flex (), enUSA, First Printing Starting and Stopping the Engine

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.

NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
Your vehicle is equipped with an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
your vehicle is used. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time. This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying a
message in the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
