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.

STARTING AND STOPPING THE
ENGINE – FREQUENTLY ASKED
QUESTIONS - GASOLINE,
VEHICLES WITHOUT: PUSH
BUTTON START
Why is the engine idle speed high when
I am starting the engine?
The speed at which the engine idles
immediately after starting is optimized
to minimize vehicle emissions and
maximize cabin comfort and fuel
economy.
Why does the engine not crank? You can only attempt to start the
engine for a limited amount of time
before the starting system temporarily
disables. If you exceed the starting
time limit, a message may appear and
you cannot attempt to start the engine
for at least 15 minutes.
Why do I experience different driving
characteristics? If you disconnect the battery, your
vehicle may exhibit some unusual
driving characteristics for
approximately 5 mi (8 km) after you
reconnect it. This is because the engine
management system must realign
itself with the engine. You can
disregard any unusual driving
characteristics during this period.
Why can I not start the engine? If you cannot start the engine after 3
attempts, wait 10 seconds and do the
following:
1. Fully press the brake pedal or the clutch pedal.
Note: Make sure that the parking brake is
applied.
Note: Make sure that the transmission is in
park (P) or neutral (N). 2. Fully press the accelerator pedal and
hold it there. 3. Turn the key to position
III and wait
until the engine stops cranking.
4. Release the accelerator pedal.
