This gauge shows you the state of
charge of the battery for the
Integrated Motor Assist (IMA). This
battery is recharged by the IMA
motor, and discharged by the IMA
when it is assisting the engine with
powering the vehicle.Since the level is not read directly,
small sensing errors can, over time,
cause the gauge to read higher than
the actual battery level. The system
will then perf orm a correction, and
the battery level gauge reading will
drop suddenly. When this happens,
IMA assist and Auto Idle Stop are
disabled until the IMA battery is
suf f iciently recharged by normal
driving.
The gauge reading may drop near
the bottom under driving conditions
that require IMA motor assistance
f or a long time, such as prolonged
acceleration or climbing a long hill.
TheIMAmotorwillrechargethe
battery as you continue driving.
The IMA battery is charged at a
higher rate when the transmission is
in LOW (L) range (see page ).
If the battery is mostly discharged,
the Auto Idle Stop f unction is
disabled (see page ).
The battery level gauge does not
read the battery level directly. It
calculates the level by continuously
measuring the current f low, voltage,
and temperature.
This correction of the battery level
gauge is normal and does not
indicate a problem. If the IMA
battery develops a problem or
becomes deteriorated, the IMA
system indicator will come on. If this
happens, have the vehicle checked
by your dealer as soon as possible.

Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
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.
If it is near or below the lower mark,
see
on page .
Wait a f ew minutes af ter turning the

Remove the dipstick (orange loop).
Wipe of f the dipstick with a clean

Improperly inf lated tires
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.
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 multi-
inf ormation display (see
on page ).
For example: If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption. Aerodynamic drag has a big ef f ect
on f uel 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.
Idling
results in 0 miles per gallon (0 kms
per liter).

Your vehicle is equipped with f ront
disc brakes. The brakes on the rear
wheels are drum. A power assist
helps reduce the ef f ort needed on
thebrakepedal.TheABShelpsyou
retain steering control when braking
very hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. It also
keeps your brake lights on all the
time, conf using drivers behind you.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 an
advanced hydraulic booster.
The advanced hydraulic booster has
some f eatures.
This f eature enables you to press the
brakepedalwithlessforcebythe
help of hydraulic pressure in the oil
pressure pump.This f eature controls the braking
pressure appropriately, coordinating
with the regenerating brake of the
IMA motor.
When you release the brake pedal
while the Auto Idle Stop f unction is
activated, this f eature keeps the
braking pressure until the engine
starts, and prevents the vehicle from
dropping back.
This f eature helps you apply the
brakes with less f orce during an
emergency braking situation.
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.

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.
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.
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 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.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.
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. 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.
