Bef ore you begin driving your
vehicle, you should know what
gasoline to use and how to check the
levels of important f luids. You also
need to know how to properly store
luggage or packages. The
inf ormation in this section will help
you. If you plan to add any
accessories to your vehicle, please

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 .
Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.
Remove the dipstick (black
handle).
Insert the dipstick all the way back
into its hole. Wipe of f the dipstick with a clean
cloth or paper towel.
To close the hood, lif t it up slightly to
remove the support rod f rom the
hole. Put the support rod back into
its holding clip. Lower the hood to
about a f oot (30 cm) above the
f ender, then let it drop. Make sure it
is securely latched. Holding the grip, pull the support
rod out of its clip. Insert the end
into the designated hole in the
hood.

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, seeon page f or

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: 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.
An underinf 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.

Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
The A/C

which makes it use more f uel. Use

Combine several short trips into

your vehicle.Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,

Fasten your seat belt. Check that
your passenger has f astened his or

When you start the engine, check
the gauges and indicators in the
instrument panel (see page ).
Check the seat adjustment (see

Make sure the doors are securely
closed and locked.
Check that the hood is f ully closed.
Check that the trunk is f ully

Visually check the tires. If a tire
looks low, use a gauge to check its
pressure.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.If you cannot make the low tire
pressure indicator go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, repair the tire with the tire
repair kit (see page ).
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
Each tire has its own pressure
sensor (not including the spare tire).
If the air pressure of a tire becomes
signif icantly low while driving, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on.
When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard. Driving on a signif icantly under
inf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.
