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.
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. An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.

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

Youshoulddothefollowingchecks
and adjustments every day bef ore
you drive your vehicle.Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice.
Check that the hood and trunk are
f ully closed.
Visually check the tires. If a tire
looks low, use a gauge to check its
pressure. Check the seat adjustment (see
page ).
Check the adjustment of the
inside and outside mirrors (see
page ).
Check the steering wheel
adjustment (see page ).
Make sure the doors are securely
closed and locked.
Fasten your seat belt. Check that
your passengers have f astened
their seat belts (see page ).
Check that any items you may be
carrying are stored properly or
f astened down securely. When you start the engine, check
the gauges and indicators in the
instrument panel, and the
messages on the multi-inf ormation
display (see pages , and
).

If there is a problem with the
starting system, you will see a

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 this message is on, the ignition

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you. The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.

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.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-inf ormation display (see page)tocomeon. When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
The multi-inf ormation display also
shows a ‘‘CHECK TIRE PRESSURE’’
message (see page ). 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.
Under-inf 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/TPMS
indicator may come on unexpectedly. For example, if you check and f ill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
youcheckandadjustyourtire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinf lated.
However, the low tire pressure/
TPMS indicator will not come on if
the tires are overinflated.
Refer to page for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to f lash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a ‘‘CHECK TPMS SYSTEM’’
message on the multi-information
display (see page ).
