Engine oil pressure gauge:
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the “L” and “H”);
if the needle goes below the
normal range, stop the vehicle as
soon as safely possible and
switch off the engine
immediately.Check the oil level.
Add oil if needed (refer to Engine oilin theMaintenance and
Specifications chapter). If the oil level is correct, have your vehicle
checked by your authorized Mazda dealership.
Fuel gauge: Displays approximately
how much fuel is in the fuel tank.
The fuel gauge may vary slightly
when the vehicle is in motion or on
a grade.
When refueling the vehicle from
empty indication, the amount of fuel
that can be added will be less than
the advertised capacity due to the reserve fuel.
NOTE: The FUEL DOOR icon and arrow indicates which side of the
vehicle the fuel filler door is located.

if an authorized Mazda fuel filter is not used.
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 fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,600 km (1,000 miles)
of driving (engine break-in period). You will get a more accurate
measurement after 3,000 km–5,000 km (2,000 miles-3,000 miles).
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 theRefill capacities
section 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 will 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 2 automatic click-offs when filling.
• Always use fuel with the recommended octane rating.
• Use a known quality gasoline, preferably a national brand.
• Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
