13. Tighten the wheel nuts securely inthe same crisscross pattern. Have
the wheel nut torque checked at
the nearest automotive service
facility.
Tighten the wheel nuts to:
80 lbf·ft (108 N·m, 11 kgf·m)
14. Store the jack in its holder. Turn the jack's end bracket to lock it in
place. Store the tools.
15. Remove the center cap from theflat tire, and store it in the cargo
area.
16. Place the flat tire face up in the cargo area.
17. Secure the flat tire by screwing the wing bolt back into its hole.
Loose items can fly around the
interior in a crash and could
seriously injure the occupants.
Store the wheel, jack, and tools
securely before driving.
18. Reinstall the cargo area floor, and close the tailgate.
19. Your vehicle's original tire has a tire pressure monitoring system
sensor. To replace a tire, refer to
Changing a Tire with TPMS (see
page 394).

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 461.
●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 mechanic to
determine the problem (see
Emergency Towing on page 475).
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 450).
You can then try jump starting the
vehicle from a booster battery (see
page 461).

5. Look for any obvious coolantleaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 475).
6. If you do not find an obvious leak, check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower before
checking the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off. 9. Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘
’’). Add coolant to the radiator
up to the base of the filler neck. If
you do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on tightly. Run the engine, and watch
the temperature gauge. If it goes
back to the H mark, the engine
needs repair (see Emergency
Towing on page 475).
11. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.

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
473 and 474, 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. (Under-hood fuse boxes) Remove the cover from the fuse
box.
3. Check each of the large fuses inthe under-hood fuse box by
looking through the side window
at the wire inside. Remove the
screws with a Phillips-head
screwdriver.FUSE BLOWN

Page 478 of 518
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 in your vehicle. Leave the
blown fuse in that circuit and have
your vehicle checked by a
qualified technician.
On models without navigation systemWhen the audio system is disabled,
the clock setting in the audio system
will be canceled. You will need to
reset the clock (see page 293).
On models with navigation systemIf the navigation system fuse is
removed, the navigation system will
disable itself. The next time you turn
on the ignition switch, the system
will require you to enter a PIN before
it can be used. Refer to the
navigation system manual.

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.(On SH-AWD models)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.
(Execpt SH-AWD models)There are two ways to tow your
vehicle:Flat-bed Equipment
- The operator
loads your vehicle on the back of a
truck. This is the best way to
transport your vehicle.
Wheel-lift Equipment
- The tow
truck uses two pivoting arms that go
under the front tires and lift them off
the ground. The rear tires remain on
the ground. This is an acceptable
way to tow your vehicle. If, due to damage, your vehicle must
be towed with the front wheels on
the ground, do this:
●Start the engine.●Shift to the D position and hold for
5 seconds, then to N.●Turn off the engine.●Leave the ignition switch in the
ACCESSORY (I) position so the
steering wheel does not lock.●Release the parking brake.

Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shift the transmission or start the
engine, your vehicle must be
transported with the front wheels off the
ground.
With the front wheels on the ground,
do not tow the vehicle more than 50
miles (80 km), and keep the speed
below 35 mph (55 km/h).
Trying to lift or tow your vehicle by the
bumpers will cause serious damage.
The bumpers are not designed to
support the vehicle's weight.
The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in the ACCESSORY (I)
position, and make sure the steering
wheel turns freely before you begin
towing.
