Turn the ignition off as soon as possible to protect the battery. This
message will clear once the vehicle has been started and the battery
state of charge has recovered. Turning off unnecessary electrical loads
while driving will allow faster battery state-of-charge recovery. See
Battery management systemin theMaintenance and Specifications
chapter for more information.
LOW BATTERY LESS FEATURES (if equipped)— Displayed when
the battery management system detects an extended low-voltage
condition. Various vehicle features will be disabled to help preserve the
battery. Turn off as many of the electrical loads as soon as possible to
improve system voltage. If the system voltage has recovered, the disabled
features will operate again as normal.

Understanding Your Tire Pressure Monitoring System (TPMS)in the
Tires, Wheels and Loadingchapter. If the warning stays on or
continues to come on, contact your authorized dealer as soon as
possible.

ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend taking
fuel economy measurements during the first 1,000 miles (1,600 km) of
driving (engine break-in period). You will get a more accurate
measurement after 2,000 miles–3,000 miles (3,000 km–5,000 km).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theMaintenance
product specifications and capacitiessection of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading may result if the engine is left running.
•Use the same filling rate setting (low — medium — high) each time
the tank is filled.
•Allow no more than three automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
•Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in miles or kilometers).
