Screw the fuel fill cap back on
until it clicks at least once. If you
do not properly tighten the cap,
you will see a ‘‘TIGHTEN FUEL
CAP’’ message on the multi-
inf ormation display (see right
column on this page), and the
malf unction indicator lamp may
also come on (see page ).
Push the f uel f ill door closed until
it latches.Your vehicle’s on board diagnostic
system will detect a loose or missing
f uel f ill cap as an evaporative system
leak. The f irst time a leak is detected
a ‘‘TIGHTEN FUEL CAP’’ message
appears on the multi-inf ormation
display. Turn the engine of f , and
conf irm the f uel f ill cap is installed. If
it is, loosen it, then retighten it until
it clicks at least once. The message
should go of f af ter several days of
normal driving once you tighten or replace the f uel f ill cap. To scroll to
another message, press the INFO
button. The ‘‘TIGHTEN FUEL CAP’’
message will appear each time you
restart the engine until the system
turns the message of f .
If the system still detects a leak in
the vehicle’s evaporative emissions
system, the malf unction indicator
lamp (MIL) comes on. If the f uel f ill
cap was not already tightened, turn
the engine of f , and check or
retighten the f uel f ill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go of f ,
have your vehicle inspected by a
dealer. For more inf ormation, see

Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.Remove the dipstick (orange loop). Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page . Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
on page f or
inf ormation on adding the proper
coolant.
Refer to
on page f or inf ormation
about checking other items on your
vehicle.
Wipe of f the dipstick with a clean
cloth or paper towel.

The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see
on page ).
For example: An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption. In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption. Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible. Idling
results in 0 miles per gallon.

Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
Combine several short trips into

Direct calculation is the

Even though you may be able to
start the engine manually without
the auto control mode of the starting
system, have your dealer inspect
your vehicle.
If there is a problem with the
starting system, you will see a
‘‘CHECK STARTING SYSTEM’’
message on the multi-inf ormation
display when the ignition switch is
turned to the ON (II) position. You
will also see this message when the
auto control mode of the starting
system has a problem.
If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine fails to start, press
the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return
to step 5.

The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400
meters) adds to this problem.
