Reasons given... Consider...
“The people I’m with don’t
wear belts” Set the example, teen deaths occur 4
times more often in vehicles with
TWO or MORE people. Children and
younger brothers/sisters imitate
behavior they see.
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea. People who are
ejected are 40 times more likely
to DIE. Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
WARNING: Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minder  chime. To
do so may adversely affect the performance of the vehicle’s airbag
system.
Deactivating/activating the Belt-Minder  feature (Driver only)
Note: If you are using MyKey  , the Belt-Minder  cannot be disabled.
Also, if the Belt-Minder  has been previously disabled, it will be
re-enabled during the use of MyKey  . Refer to MyKey  in the Locks and
Security chapter.
The Belt-Minder  feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that the following conditions
are met:
• the parking brake is set
• the gearshift is in P (Park)
• the ignition switch is in the off position
• all vehicle doors are closed
• the driver’s safety belt is unbuckled
• the parking lamps/headlamps are in the off positionSeating and Safety Restraints

If the engine fails to start using the preceding instructions (flexible
fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Guarding against Exhaust Fumes
WARNING: If you smell exhaust fumes inside your vehicle, have
this checked 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 leave the engine idling for long periods of
time, we recommend that you do one of the following:
• Open the windows at least one inch (2.5 centimeters).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The engine block heater plug can be located through the center
opening of the lower front bumper assembly. The block heater system is
most effective when outdoor temperatures reach below 0°F (-18°C).
For flexible fuel vehicles, if operating with E85 ethanol, an engine block
heater must be used if ambient temperature is below 0°F (-18°C).
See Cold weather starting earlier in this chapter for more information
on starting with ethanol.
WARNING: Failure to follow engine block heater instructions
could result in property damage or physical injury. Driving

WARNING: To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
• For your safety, use an outdoor extension cord that is product
certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly marked “Suitable for Use
with Outdoor Appliances.” Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
• Use a 16 gauge outdoor extension cord, minimum.
• Use as short an extension cord as possible.
• Do not use multiple extension cords. Instead, use one extension cord
which is long enough to reach from the engine block heater cord to
the outlet without stretching.
• Make certain that the extension cord is in excellent condition (not
patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.
• To reduce the risk of electrical shock, do not use your heater with
ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.
• Make sure that when in operation, the extension cord plug /engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.
• Be sure that areas where the vehicle is parked are clean and clear of
all combustibles such as petroleum products, dust, rags, paper and
similar items.
• Be sure that the engine block heater, heater cord and extension cord
are solidly connected. A poor connection can cause the cord to
become very hot and may result in an electrical shock or fire. Be sure
to check for heat anywhere in the electrical hookup once the system
has been operating for approximately a half hour.
• Finally, have the engine block heater system checked during your fall
tune-up to be sure it’s in good working order.Driving
