   Indicates the engine speed in revolutions per minute (RPM x 1000).
   CAUTION!
   Do not operate the engine with the tachometer pointer in the red area. Engine damage will occur.
2. Temperature Gauge
   The temperature gauge shows engine coolant temperature. Any reading within the normal range indicates that the engine cooling system is operating satisfactorily.
   The pointer will likely indicate a higher temperature when driving in hot weather, up mountain grades, or when towing a trailer. It should not be allowed to exceed the upper limits of the normal operating range.
   WARNING!
   A hot engine cooling system is dangerous. You or others could be badly burned by steam or boiling coolant. You may want to call an authorized dealer for service if your vehicle overheats.
   CAUTION!
   Driving with a hot engine cooling system could damage your vehicle. If the temperature gauge reads “H” pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the “H”, turn the engine off immediately and call an authorized dealer for service.
3. Instrument Cluster Display
   The instrument cluster display features a driver interactive display. Refer to “Instrument Cluster Display” in this chapter for further information.

BATTERY SAVER ON/BATTERY SAVER

MODE MESSAGE — ELECTRICAL LOAD  REDUCTION ACTIONS — IF EQUIPPED  

This vehicle is equipped with an Intelligent Battery Sensor (IBS) to perform additional monitoring of the electrical system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or the vehicle battery conditions are deteriorating, electrical load reduction actions will take place to extend the driving time and distance of the vehicle. This is done by reducing power to or turning off non-essential electrical loads.
Load reduction is only active when the engine is running. It will display a message if there is a risk of battery depletion to the point where the vehicle may stall due to lack of electrical supply, or will not restart after the current drive cycle.
When load reduction is activated, the message “Battery Saver On” or “Battery Saver Mode” will appear in the instrument cluster display.
These messages indicate the vehicle battery has a low state of charge and continues to lose electrical charge at a rate that the charging system cannot sustain.

NOTE

• The charging system is independent from load reduction. The charging system performs a diagnostic on the charging system continuously.
• If the Battery Charge Warning Light is on it may indicate a problem with the charging system. Refer to “Battery Charge Warning Light” in this chapter for further information.

The electrical loads that may be switched off (if equipped), and vehicle functions which can be affected by load reduction:

• Heated Seat/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 150W Power Inverter System
• Audio and Telematics System

Loss of the battery charge may indicate one or more of the following conditions:

• The charging system cannot deliver enough electrical power to the vehicle system because the electrical loads are larger than the capability of charging system. The charging system is still functioning properly.
• Turning on all possible vehicle electrical loads (e.g. HVAC to max settings, exterior and interior lights, over-loaded power outlets +12 Volt, 150W, USB ports) during certain driving conditions (city driving, towing, frequent stopping).
• Installing options like additional lights, upfitter electrical accessories, audio systems, alarms and similar devices.
• Unusual driving cycles (short trips separated by long parking periods).
• The vehicle was parked for an extended period of time (weeks, months).
• The battery was recently replaced and was not charged completely.
• The battery was discharged by an electrical load left on when the vehicle was parked.
• The battery was used for an extended period with the engine not running to supply radio, lights, chargers,
• 12 Volt portable appliances like vacuum cleaner’s, game consoles and similar devices.

What to do when an electrical load reduction action message is present (“Battery Saver On” or “Battery Saver Mode”)

During a trip:

• Reduce power to unnecessary loads if possible:
  • Turn off redundant lights (interior or exterior)
  • Check what may be plugged in to power outlets 12 Volt, 150W, USB ports
  • Check HVAC settings (blower, temperature)
  • Check the audio settings (volume)

After a trip

• Check if any aftermarket equipment was installed
• additional lights, upfitter electrical accessories, audio systems, alarms) and review specifications if any (load and Ignition Off Draw currents).
• Evaluate the latest driving cycles (distance, driving time and parking time).
• The vehicle should have service performed if the message is still present during consecutive trips and the evaluation of the vehicle and driving pattern did not help to identify the cause.
