Temperature Gauge

•

The Temperature Gauge indicates the extreme temperature of

major components:

– Traction battery

– TIM

– Motor/transaxle

– Coolant

•

If the temperature of any of these components is not within

desirable limits, the needle will move into the H (hot) or

C (cold) areas.

– The traction battery is the only component that can cause the

needle to move into the cold area.

– If the traction battery is too cold and another component is too

hot, the temperature gauge will display the hot condition.

•

The IAA monitors systems that produce heat and uses the

Temperature Gauge to indicate an overheating condition or

a cold condition in the case of the traction battery.

Speedometer/Odometer/Tripmeter

Speedometer/Odometer/Tripmeter

•

The speedometer (A) is an electronically driven 0-130 km/h

(0-80 mph) gauge with a carryover Ranger odometer (B) and

tripmeter.

•

The IAA monitors the ABS module for input from the rear

anti-lock brake system speed sensor. This input is used to indicate

vehicle speed.
