Auto-Reverse
The power tailgate has an auto-
reverse feature. If it meets resistance
while opening or closing, it will beep
three times and reverse direction.
However, the tailgate may not
reverse immediately. Always make
sure passengers and objects are clear
of the tailgate before opening or
closing it.
Closing a power tailgate while
anyone is in the path of the
tailgate can cause serious
injury.
Make sure everyone is clear
before closing the power
tailgate.
Also check that passengers,
especially children, do not have their
hands on the edge of the tailgate or
on the tailgate sill. The auto reverse
feature stops working when the
tailgate is about to latch so the motor
can pull the tailgate shut.
If your vehicle's battery is
disconnected, goes dead, or the fuse
is removed while the tailgate is fully
open, the power tailgate needs to be
reset. After connecting the battery or
installing the fuse, close the tailgate
fully by hand.
The power tailgate may not open or
close under the these conditions:
The vehicle is parked on a steep
hill.
When the vehicle is swayed in a
strong wind.
When the tailgate or the roof is
covered with snow or ice.
Do not install any accessories on the
tailgate. It may cause the tailgate not
to function properly. If there is snow
or ice on the tailgate, make sure to
remove it before you operate the
tailgate.
If you push the tailgate release
button inside the handle while the
tailgate is opening or closing, it will
stop moving. You need to open or
close it the rest of the way manually.
The tailgate has sensors on both
sides. Be careful not to damage
them. If the sensors are damaged,
the power tailgate does not function
properly.

pull back the window switch firmly to
the second detent, then release it.
The window automatically goes all
the way up. To stop the window from
going all the way up, push down on
the window switch briefly.
When you push the MAIN switch in,
the switch is off, and the passengers'
windows cannot be raised or
lowered. To cancel this feature, push
on the switch again to get it to pop
out. Keep the MAIN switch pushed
in when you have children in the
vehicle so they do not injure
themselves by operating the

If either front
window senses any obstacle while it
is closing automatically, it will
reverse direction and then stop. To
close the window, remove the
obstacle, then use the window switch
again.
Auto reverse stops sensing when the
window is almost closed. You should
always check that all passengers and
objects are away from the window
before closing it.
If your vehicle's battery is
disconnected or goes dead, or the
driver's window fuse is removed, the
AUTO function may be disabled. If
the AUTO function is disabled, the
power window system will need to be
reset after reconnecting the battery
or installing the fuse.
1. Start the engine. Push down and
hold the driver's window switch
until the window is fully open.
2. Pull and hold the driver's window
switch to close the window
completely, then hold the switch

Your vehicle's audio system may
disable itself if it is disconnected
from electrical power for any reason.
To make it work again, you must
enter a specific five-digit code with
the preset buttons. Because there are
hundreds of number combinations
possible from the five digits, making
the system work without knowing
the exact code is nearly impossible.
You should have received a card that
lists your audio system code number
and serial number. It is best to store
this card in a safe place at home. In
addition, you should write the audio
system's serial number in this
owner's manual.
If you lose the card, you must obtain
the code number from your dealer.
To do this, you will need the audio
system's serial number.
If your vehicle's battery is
disconnected or goes dead, or the
radio fuse is removed, the audio
system will disable itself. If this
happens, you will see
‘‘
’’
in
the audio display the next time you
turn on the system. Use the preset
buttons to enter the five-digit code.
The code is located on the radio code
card included in your owner's
manual kit. When it is entered
correctly, the radio will start playing.
If you make a mistake entering the
code, do not start over; complete the
five-digit sequence, then enter the
correct code. You have 10 tries to
enter the correct code. If you are
unsuccessful in 10 attempts, you
must then leave the system on for 1
hour before trying again.
The system will retain your AM and
FM presets even if power is
disconnected.

Charging necessary
Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent further
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (
) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
If the radio fuse is removed, the
audio system will disable itself. The

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:
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, 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. 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
432
.
Turn the ignition switch to the
START (III) position. 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
446
.
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
421
). You
can then try jump starting the
vehicle from a booster battery (see
page
432
).
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,
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
).

Are you using the proper starting
procedure? Refer to
Starting the
Engine
on page
339
.
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
440
).
If you find nothing wrong, you will
need a qualified technician to find the
problem. See
Emergency Towing
on
page
446
.
Jump Starting
Although this seems like a simple
procedure, you should take several
precautions.
A battery can explode if you do
not follow the correct
procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
You cannot start your vehicle by
pushing or pulling it.
To Jump Start Your Vehicle:
1. Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.
If a battery sits in extreme cold, the
electrolyte inside can freeze. Attempting
to jump start with a frozen battery can
cause it to rupture.
2. Turn off all the electrical
accessories: heater, A/C, climate
control, audio system, lights, etc.
Put the transmission in neutral or
Park, and set the parking brake.

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
443
,
444
, and
445
, 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.
2. Remove the cover from the fuse
box.
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.

4. Check the smaller fuses in the
under-hood fuse boxes and rear
fuse box, and all the fuses in the
interior and rear fuse boxes by
pulling out each one with the fuse
puller provided in the primary
under-hood fuse box.
5. Look for a burned wire inside the
fuse. If it is burned out, replace it
with one of the spare fuses of the
same rating or lower.
If you cannot drive the vehicle
without fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sure you can do without that circuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
fuse with one of the correct rating as
soon as you can.

Replacing a fuse with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement fuse with the proper rating
for the circuit, install one with a lower
rating.
6. 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
qualified technician.
If the radio fuse is removed, the
audio system will disable itself. The

To open the fuel fill door, pull the
release lever rearward.
Emergency Towing
If your vehicle needs to be towed,
call a professional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The only way you can safely tow
your vehicle is with flat-bed
equipment.
The operator will load
your vehicle on the back of a truck.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inform
them a flat-bed is required.
Towing with only two tires on the
ground will damage parts of the all-
wheel-drive system. Your vehicle should
be transported on a flat-bed truck or
trailer.
