ENGINE BLOCK HEATER (If Equipped)
Engine Block Heater Precautions
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. 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 engine block
heater cord plug connections are free
and clear of water. This could cause an
electric shock or fire.
• If the engine 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. •
Park your vehicle in a clean area, clear
of combustible materials.
• Firmly connect the engine block heater
cord and the extension cord.
• Check the extension cord for heat
anywhere when the system has been
operating for approximately 30 minutes.
• Unplug and properly stow the system
before starting and driving your vehicle.
The protective cover seals the terminals
of the engine block heater cord plug
when not in use.
• Check the engine block heater system
for proper operation before winter.
How Does the Engine Block Heater
Work
The engine block heater warms the engine
coolant. This allows the climate control
system to quickly respond. The equipment
includes a heater element installed in the
engine block and a wire harness. You can
connect the system to a grounded 220-240
volt AC electrical source.

FUEL QUALITY
Selecting the Correct Fuel
Your vehicle operates on regular unleaded
gasoline with a minimum pump (R+M)/2
octane rating of 87.
Some fuel stations, particularly those in high
altitude areas, offer fuels posted as regular
unleaded gasoline with an octane rating
below 87. The use of these fuels could result
in engine damage that will not be covered
by the vehicle Warranty. For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well as
other conditions, for example when towing
a trailer. See Towing a Trailer (page 299).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal vehicle
and engine performance.
For additional information, visit
www . toptiergas. com .
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty. Do not use:
•
Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based additives,
including manganese-based compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl manganese
tricarbonyl, which is a manganese-based fuel
additive, will impair engine performance and
affect the emission control system.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of your
vehicle's emissions system and filters harmful
pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off.
To avoid damaging the catalytic converter:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting Precautions (page 309).
• Use the correct fuel.
See Fuel and
Refueling (page 197).
• Do not switch the ignition off when your
vehicle is moving. •
Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Do not make any unauthorized
changes to your vehicle or engine. By law,
vehicle owners and anyone who
manufactures, repairs, or services a fleet of
vehicles are not permitted to intentionally
remove an emission control device or
prevent it from working.
CATALYTIC CONVERTER –
TROUBLESHOOTING
Catalytic Converter – Warning Lamps
Your vehicle has an on-board diagnostics
system that monitors the emission control
system. If any of the following warning lamps
illuminate, this may indicate that the on-board
diagnostics system has detected an emission
control system malfunction.
