3. Remove the fuel fill cap slowly.You may hear a hissing sound as
pressure inside the tank equalizes.
Place the cap in the holder on the
fuel fill door.
4. Stop filling the tank after the fuel nozzle automatically clicks off. Do
not try to ‘‘top off ’’the tank. This
leaves some room in the fuel tank
for the fuel to expand with
temperature changes.
If the fuel nozzle keeps clicking off
even though the tank is not full,
there may be a problem with your
vehicle's fuel vapor recovery
system. The system helps keep
fuel vapor from going into the
atmosphere. Try filling at another
pump. If this does not fix the
problem, consult your dealer. 5. 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-information
display (see right column on this
page), and the malfunction
indicator lamp may also come on
(see page 466).
6. Push the fuel fill door closed until it latches. Tighten Fuel Cap Message
If your fuel fill cap is loose or
missing, a
‘‘TIGHTEN FUEL CAP ’’
message appears on the multi-
information display after you start the
engine.

Turn the engine off, and confirm the
fuel fill cap is installed. If it is, loosen
it, then retighten it until it clicks at
least once. When you can restart the
engine, the message appears again.
The message goes off after several
days of normal driving once you
tighten or replace the fuel fill cap. To
scroll to another message, press the
INFO (
/
) button.
If the system still detects a leak in
your vehicle's evaporative emissions
system, the malfunction indicator
lamp (MIL) comes on. If the fuel fill
cap was not already tightened, turn
the engine off, and check or
retighten the fuel fill 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 off,
have your vehicle inspected by a
dealer. For more information, see
page 466. Opening and Closing the Hood
1. Park the vehicle, and set the
parking brake. Pull the hood
release handle located under the
lower left corner of the dashboard.
The hood will pop up slightly.
2. Put your fingers under the frontedge of the hood near the center.
Slide your hand to the left until
you feel the hood latch handle.
Push this handle up to release it.
Lift up the hood.
If the hood latch handle moves stiffly,
or if you can open the hood without
lifting the handle, the mechanism
should be cleaned and lubricated.

3. Holding the grip, pull the supportrod out of its clip. Insert the end
into the designated hole in the
hood. To close the hood, lift it up slightly to
remove the support rod from the
hole. Put the support rod back into
its holding clip. Lower the hood to
about a foot (30 cm) above the
fender, then let it drop. Make sure it
is securely latched.
Oil Check
Park the vehicle on a level surface.
Wait a few minutes after turning the
engine off before you check the oil.
1. Remove the dipstick (orange loop).
2. Wipe off the dipstick with a clean
cloth or paper towel.
3. Hold the dipstick with a clean cloth or paper towel, and then
insert it all the way back in its
hole.

Make sure the‘‘UP ’’mark on the
loop is facing up when you insert
the dipstick.
4. 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 Adding Engine Oil on page 420.Engine Coolant Check
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
Adding
Engine Coolant on page 424 for
information on adding the proper
coolant. Refer to
Owner's Maintenance
Checks on page 417 for information
about checking other items on your
vehicle.

Fuel Economy FactorsThe following factors can lower your
vehicle's fuel economy:●Aggressive driving (hard
acceleration and braking)●Excessive idling, accelerating and
braking in stop-and-go traffic●Cold engine operation (engines are
more efficient when warmed up)●Driving with a heavy load or the air
conditioner running●Improperly inflated tires
Improving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
information display (seeOwner's
Maintenance Checks on page 417).
For example:●Use the required engine oil (see
page 420).●Maintain proper tire inflation -
An underinflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.●Avoid carrying excess weight in
your vehicle -It puts a heavier
load on the engine, increasing fuel
consumption.
●Keep your vehicle clean -In
particular, a build-up of snow or
mud on your vehicle's underside
adds weight and rolling resistance.
Frequent cleaning helps your fuel
economy.

Drive Efficiently●Drive moderately-Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.●Observe the speed limit -
Aerodynamic drag has a big effect
on fuel economy 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.
●Always drive in the highest gear
possible -If your vehicle has a
manual transmission, you can
boost your fuel economy by up
shifting as early as possible.●Avoid excessive idling -Idling
results in 0 miles per gallon (0 kms
per liter).
●Minimize the use of the air
conditioning system -The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.●Plan and combine trips -
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one.

You should do these checks and
adjustments before you drive your
vehicle:1. Make sure all windows, mirrors, and outside lights are clean and
unobstructed. Remove frost, snow,
or ice.
2. Check that the hood is fully closed.
3. Visually check the tires. If a tire looks low, use a gauge to check its
pressure.
4. Check that any items you may be carrying are stored properly or
fastened down securely. 5. Check the seat adjustment (see
page 134).
6. Check the adjustment of the inside and outside mirrors (see page
146).
7. Check the steering wheel adjustment (see page 122).
8. Make sure the doors and the tailgate are securely closed and
locked.
9. Fasten your seat belt. Check that your passengers have fastened
their seat belts (see page 15). 10. When you start the engine, check
the gauges and indicators in the
instrument panel, and the
messages on the multi-information
display (see pages 63, 73 and 74).
