If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
If this 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. 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.
If the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Ittakes
several days of driving under various
conditions to set the codes again.
If your vehicle has an automatic
transmission, the malf unction
indicator lamp may also come on
with the ‘‘D’’ indicator.
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.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display.

ÎIf 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 feel 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 feel the brake
pedal go down much farther before
the vehicle begins to slow down,
and you will have to press harder
on the pedal. You will also see a ‘‘LOW BRAKE
FLUID’’ message on the multi-
inf ormation display.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display when this
indicator comes on.
To check if they are set, turn the
ignition switch to the ON (II)
position (set the power mode to ON,
on models with keyless access
system), 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 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 ). 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 f uel f ill door release button
does not work, use the release lever
inside the lef t maintenance lid in the
trunk.To open the f uel f ill door, pull the
release lever rearward.
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 by
your dealer as soon as possible (see
on 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.
If you also cannot unlock the trunk
due to the power door lock system

Check each of the large f uses in

Removing these f uses requires a

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem with your
vehicle. Leave the blown fuse in
that circuit, and have your vehicle
checked by a qualif ied technician.
If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate that anything is wrong.
Replace the f use with one of the
correct rating as soon as you can.
Your vehicle has spare fuses on the
back of the under-hood f use box
cover. 6.

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.
