When you turn the ignition switch to
the START (III) position or on
models with keyless access system,
press the engine start/stop button to
set START Mode (see page ),
you do not hear the normal noise of
the engine trying to start. You may
hear a clicking sound, a series of
clicks, or nothing at all.
Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START
Mode (see page ):
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run. You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly. Check these things:
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or neutral. Turn the ignition switch to the ON
(II) position or on models with
keyless access system, press the
engine start/stop button to set ON
Mode (see page ). Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See

In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START
Mode (see page ), but the engine
does not run.
Turn the ignition switch to the
START (III) position or on models
with keyless access system, press
the engine start/stop button to set
STARTMode(seepage ).If
the headlights do not dim, check
the condition of the fuses. If the
f uses are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. See
on page .If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page
).
Are you using a properly coded
key or keyless access remote (on
models with keyless access
system)? An improperly coded key
or keyless access remote will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).65

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.
