If you see a‘‘CHECK DRL SYSTEM ’’
message on the multi-information
display, there is a problem with the
daytime running light system. Take
your vehicle to a dealer to have it
checked.
When the multi-information display
shows a ‘‘DRL OFF ’’message, the
daytime running lights are off. DRL
will turn on when the parking brake
is released. Automatic Lighting Off Feature
This feature turns off the headlights,
all other exterior lights, and the
instrument panel lights within 15
seconds after you remove the key
and close the driver's door.
To change the
‘‘HEADLIGHT AUTO
OFF TIMER ’’setting, see page 125.
The automatic lighting off feature
activates if you remove the key (or
the vehicle is in VEHICLE OFF
mode on models with keyless access
system), and open or close driver's
door with the headlight switch in the
‘‘
’’ or ‘‘
’’position, or the
lights turned on in the ‘‘AUTO ’’
position. If you turn the ignition switch to the
LOCK (0) position with the headlight
switch on, but do not open the door,
the lights turn off after 10 minutes (3
minutes, if the switch is in the
‘‘
AUTO ’’position).
The lights turn on again when you
unlock or open the driver's door.
If you unlock the door, but do not
open it within 15 seconds, the lights
go off. With the driver's door open,
you will hear a lights-on reminder
chime.
Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. VEHICLE OFF (LOCK)
mode is the equivalent of LOCK (0).
See page 196 for ignition switch and
power mode comparison.

The security system helps to protect
your vehicle and valuables from
theft. The horn sounds and a
combination of headlights, position
lights, side marker lights and

unlock the driver's door with the key
or the remote transmitter/keyless
access remote.
The security system automatically
sets 15 seconds after you lock the
doors, hood, and the tailgate. For the
system to activate, you must lock the
doors and the tailgate from the
outside with the key, driver's lock
tab, door lock master switch, or
remote transmitter/keyless access
remote. The security system
indicator on the instrument panel
starts blinking immediately to show
you the system is setting itself.
Once the security system is set,
opening any door, the tailgate, or the
hood without using the key or the
remote transmitter/keyless access
remote, will cause it to alarm. It also
alarms if the audio unit is removed
from the dashboard or the wiring is
cut.The security system will not set if the
hood, tailgate, or any door is not fully
closed. If the system will not set,
check that the doors, the tailgate and
the hood are fully closed.
Do not attempt to alter this system or
add other devices to it.

Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
cargo area or pull a trailer,
readjustment may be required.
Adjustments should be done by your
dealer or another qualified
technician.
Low/High Beam Headlight Bulb
Replacement
The low/high beam headlight bulbs
are a type of high voltage discharge
tube. High voltage can remain in the
circuit even with the light switch off
and the key removed (or the vehicle
is in VEHICLE OFF (LOCK) mode
on models with keyless access
system). Because of this, you should
not attempt to examine or change a
low/high beam headlight bulb
yourself. If a low/high beam
headlight bulb fails, take the vehicle
to your dealer to have it replaced.Replacing Front Turn Signal/
Parking and Side Marker Light
Bulbs

2. Remove the front bulkhead cover
and engine compartment covers
(see page 544).

Diagnosing why the engine won't
start falls 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 194):●You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or
operates very slowly.●You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.Nothing Happens or the Starter
Motor Operates Very Slowly
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 194), 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.
Check these things:
●Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
●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 194). 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
Jump Starting
on page 587.●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 194). If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
Emergency Towing on page 602.

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
connections (see page 573). You
can then try jump starting the
vehicle from a booster battery (see
page 587).
The Starter Operates Normally
In this case, the starter motor's speed
sounds normal, or even faster 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
194), but the engine does not run.●Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page 70).
On models with keyless access system●Do you have your keyless access
system remote with you? The
vehicle will not start without the
remote within operating range.
The vehicle will not start without
the remote within operating range
and with the keyless access main
switch in the glove box turned on.●Are you using the proper starting
procedure? Refer to Starting the
Engine on page 475.●Do you have fuel? Check the fuel
gauge; the warning indicator may
not be working.●There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses (see
page 596). If you find nothing wrong, you will
need a qualified technician to find the
problem. See
Emergency Towing on
page 602.
NOTE: If you are unable to stop the
engine normally while in the Park
position, see Emergency Engine
Stop on page 200.

The primary under-hood fuse box is
on the passenger's side. The
secondary fuse box is located next to
the battery.
To open it, push the tabs as shown.Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
599, 600, and 601, or the diagram on
the fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.
1. Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are off.
Models equipped with the keyless
access system have an engine
start/stop button instead of an
ignition switch. VEHICLE OFF
(LOCK) mode is the equivalent of
LOCK (0). See page 196 for
ignition switch and power mode
comparison.
2. Remove the cover from the fusebox.
3. Check each of the large fuses in the under-hood fuse boxes by
looking through the top at the wire
inside. Removing these fuses
requires a Phillips-head
screwdriver.FUSE BLOWN
