Fuel Gauge
Indicates approximately how much fuel is left in the fuel tank (when the
ignition is on). The fuel gauge may vary slightly when the vehicle is in
motion or on a grade. The fuel icon and arrow indicates which side of
the vehicle the fuel filler door is located.
Engine Coolant Temperature Gauge
Indicates engine coolant temperature. At normal operating temperature,
the level indicator will be in the normal range. If the engine coolant
temperature exceeds the normal range, stop the vehicle as soon as safely
possible, switch off the engine and let the engine cool.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle should stay in the normal
operating range. If the needle falls below the normal range, stop the
vehicle, turn off the engine and check the engine oil level. Add oil if
needed. If the oil level is correct, have your vehicle checked at your
authorized dealer.

the vehicle as soon as possible, switch off the engine and let
cool.

It is best not to alternate repeatedly between gasoline and E85. If you do
switch fuels, it is recommended that you add as much fuel as
possible—at least half a tank. Do not add less than five gallons (18.9L)
when refueling. You should drive the vehicle immediately after refueling
for at least 5 miles (8 km) to allow the vehicle to adapt to the change in
ethanol concentration. If you exclusively use E85 fuel, it is recommended
to fill the fuel tank with regular unleaded gasoline at each scheduled oil
change.
Octane Recommendations
“Regular” unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as “Regular” with
an octane rating below 87,
particularly in high altitude areas. Fuels with octane levels below 87 are
not recommended.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
•Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
•The service engine soon indicator may come on. For more information
on the service engine soon indicator, refer to theInstrument Cluster
chapter.
SeeSettingsin theInstrument Clusterchapter for information on
calculating DTE (Distance to empty).
