Screw the fuel fill cap back on
until it clicks at least once.
even though the tank is not full,
there may be a problem with your
vehicle’s fuel vapor recovery
system. The system helps keep
fu el vapors from going into the
atmosphere. Try filling at anoth er
pump. If this does not fix the
problem, consult your dealer.
Stop
filling the tank after the fuel
nozzle automatically clicks off. Do
not try to ‘‘top off’’ the tank. Leave
some room for the fuel to expand
with temperature changes.
Remove
the fuel fill cap slowly.
You may hear a hissing sound as
pressure inside the tank escapes.
Place the cap in the holder on the
fu el fill door. If you do not properly tighten the cap,
you will see a ‘‘CHECK FUEL CAP’’
message on the information display
(see the next column).
If you do not properly tighten the cap,
you will see a ‘‘TIGHTEN FUEL
CAP’’ message on the multi-
inf ormation display (see page ). Push the f uel f ill door closed until
it latches. If your f uel f ill cap is loose or
missing, a ‘‘CHECK FUEL CAP’’
message appears on the information
display af ter you start the engine.

Park the vehicle on a level surface.
Wait a few minutes after turning the
engine off before you check the oil.
Remove the dipstick (orange loop).
Wipe off the dipstick with a clean
cloth or paper towel.
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.
Remove the dipstick again, and
ch eck 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 for
info rmation on adding the proper
coolan t.

Your vehicle still has normal f ront-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible. If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
inf ormation display, there is problem
with the SH-AWD system.
If the SH-AWD indicator blinks while
driving, it indicates the dif f erential
temperature is too high. You will also
see an ‘‘SH-AWD DIFF TEMP
HIGH’’ message on the multi-
inf ormation display. If this happens,
pull to the side of the road when it is
saf e, shif t to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked,
Each torque indicator is displayed as
a bar graph divided into 5 segments.
The number of segments represents
the amount of torque distributed to
each wheel.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist using negative pressure
generated by the engine and the
el ectric vacuum pump helps reduce
the effort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.
All four brakes have audible brake
wear indicato rs.
The
hydraulic system that operates
the brakes has two separate circuits.
Ea ch circuit works diagonally across
the vehicle (the left-front 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 distincti ve, 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 norm al for
the brakes to occasionally squeal or
squeak when you apply them.
Resting
your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness.
It also keeps your brake lights on all
the time, confusing drivers behind
you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effective-
ness. Use the engine to assist the
brakes by taking your foot off the
accelerator and downshifting to a
lower gear.
Check your brakes after driving
th rough deep water. Apply the
brakes moderate ly to see if they feel
norm al. If not, apply them gently and
frequently until they do. Be extra
cautious and alert in your driving.
When
the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
f requently af ter the engine is started.
For more inf ormation about the
electric vacuum pump, see page . 396

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. Al
though your tire pressure is
monito red, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when cold, and
set to the recommended inflation
pressure as specified on the vehicle
placard and in the owner’s manual
(see page ).
Driving on a signifi cantly under-
inflated tire causes the tire to
ov erheat and can lead to tire failure.
Under-infl ation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability. When
the low tire pressure indicator
is on, one or more of your tires is
signifi cantly underinflated. 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 information placard.
Each
tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on.
With this indicator on, you will see
which tire is losing the pressu re on
the multi-information display along
with a ‘‘CHECK TIRE PRESSU RE’’
message (see page ).
With
this indicator on, you will see
which tire is losing the pressu re on
thetirepressure monitor(seepage
).

The VSA system cannot enhance the
vehicle’s driving stability in all
situ ations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
The
vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. You will also see
the VSA activation indicator blink. When
VSA activates, you will see the
VSA activation indicator blink (see
page ).
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on, or comes
back on while driving, have the VSA
system inspected by your deale r.
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehic le as
soon as possible. You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display (see page ).
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
When you put a spare tire on the
wheel, TPMS indicator or ‘‘CHECK
TPMS SYSTEM’’ message
(depending on the models) may
come on. When the indicator or
message is on, you are unable to turn
of f the VSA system with the VSA
OFF switch.
