If the indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage.
If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by your dealer as soon as
possible.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. Tighten the cap until it
clicks at least once. Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving. The indicator may also come on with
the ‘‘D’’ indicator.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display (see
page ).
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.
Refer to for
more information (see page ).
If the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Itcan
take several days of driving under
various conditions to set the codes
again.

If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

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.
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 (see
on page ).
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display (see page ). If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.
The brake system indicator (red)
normallycomesonwhenyouturn
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 (red)
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 the next time you
stop at a service station (see page
).
You will also see a ‘‘BRAKE FLUID
LOW’’ message on the multi-
inf ormation display (see page ). 77391

The brake system indicator (amber)
on the instrument panel normally
comes on f or a f ew seconds when
you turn the ignition switch to the
ON (II) position. If it stays on af ter
the engine starts, press on the brake
pedal with your f oot several times
until the indicator turns of f . If the
indicator is still on or comes on again
after this procedure, there is a
problem in the brake system
including the electric vacuum pump.
If this happens, the brake pedal
might f eel heavy when you press it.
Have your vehicle checked by your
dealer.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display (see page ).
Your vehicle has an electric vacuum
pump located in the engine
compartment. It enhances the
ef f ectiveness of your vehicle’s brake
system more f requently when you
drive in cold weather or thinner air at
high altitude af ter the engine is
started.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualif ied technician.
If the audio f use is removed, the
audio system will disable itself . The
next time you turn on the audio you
will see ‘‘ ’’ on the display.
Use the preset bars or buttons
(depending on models) to enter the
f ive-digit code (see page ).
When the audio system is disabled,
the clock setting in the audio system
will be canceled. You will need to
reset the clock (see page ). If the navigation system f use is
removed, the navigation system will
disableitself.Thenexttimeyouturn
on the ignition switch, the system
will require you to enter a PIN
bef ore it can be used. Ref er to the
Navigation System Owner’s Manual.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.
