2008 HONDA RIDGELINE light

However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (seeon page ).
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
The brake system
indicator normally
comes on when
you turn the ignition switch to the
ON (II) position, and as a reminder
to check the parking brake. It will
stay on if you do not f ully release the
parking brake.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ). If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.
If the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads. 298

The vehicle’s f uses are contained in
threefuseboxes.The primary under-hood f use box is
on the passenger’s side. The
secondary f use box is next to the
brake f luid reservoir. To open them,
pushthetabsasshown.
The interior f use box is on the
driver’s lower lef t side. To remove
the f use box lid, put your f inger in
the notch on the lid, and pull it
outward slightly, then pull it toward
you and take it out of its hinges. If something electrical in your
vehicle stops working, check f or a
blown f use f irst. Determine f rom the
chart on pages and , or the
diagram on the f use box lid, which
f use or f uses control that device.
Check those f uses f irst, but check all
the f uses bef ore deciding that a
blown f use is the cause. Replace any
blown f uses, and check if the device
works.

Check the smaller f uses in the
under-hood f use boxes and all the
fuses in the interior fuse box by
pulling out each one with the f use
puller provided in the primary
under-hood f use box.
Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f .
Check each of the large f uses in
the primary under-hood f use box
by looking through the side
window at the wire inside.
Removing these f uses requires a
Phillips-head screwdriver.
Remove the cover f rom the f use

ÎThe burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
In Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The positive
crankcase ventilation valve routes
them from the crankcase back to the intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard ref ueling vapor
recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .

If you take your vehicle f or an
emissions test shortly af ter the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain ‘‘readiness
codes’’ that must be set in the on-
board diagnostics f or the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several days
of driving under a variety of
conditions.
If the testing f acility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the vehicle retested within the
next two or three days, you can
condition the vehicle f or retesting by
doing the f ollowing.Make sure the gas tank is nearly,
but not completely, f ull (around
3/4). Without touching the accelerator
pedal, start the engine, and let it
idle f or 20 seconds.
Make sure the vehicle has been
parked with the engine of f f or 6
hours or more.
Make sure the ambient
temperature is between 40° and
95°F.
Keep the vehicle in Park. Increase
the engine speed to 2,000 rpm, and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (about 3 minutes).
Without touching the accelerator
pedal and let the engine idle f or 20
seconds.Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
f or at least 20 minutes. Drive on
the highway in D. Do not use the
cruise control. When traf f ic allows,
drive f or 90 seconds without
moving the accelerator pedal.
(Vehicle speed may vary slightly;
this is okay.) If you cannot do this
f or a continuous 90 seconds
because of traf f ic conditions, drive
f or at least 30 seconds, then repeat
it two more times (f or a total of 90
seconds).
