How to Use the Engine Block Heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of power per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three hours will not improve system performance and will
unnecessarily use additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.

BRAKES

Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.

Four-wheel anti-lock brake system (ABS) (if equipped)
Your vehicle may be equipped with an anti-lock braking system (ABS).
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking. The ABS operates by detecting the
onset of wheel lockup during brake application and compensates for this
tendency. Noise from the ABS pump motor and brake pedal pulsation
may be observed during ABS braking; any pulsation or mechanical noise
you may feel or hear is normal. In addition, the ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal.
