If you have a flat tire while driving,
stop in a safe place to change it.
Drive slowly along the shoulder until
you get to an exit or an area that is
far away from the traffic lanes.
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.1. Park the vehicle on firm, level, and
non-slippery ground. Put the
transmission in Park. Apply the
parking brake.
If you are towing a trailer, unhitch
it.
2. Turn on the hazard warning lights, and turn the ignition switch to the
LOCK (0) position. Have all
passengers get out of the vehicle
while you change the tire.
3. Open the tailgate. Raise the cargoarea floor lid by lifting it up with
the strap, then remove the lid.
The spare tire, jack, and tools are
under the cargo area floor.
4. Unscrew the wing bolt. Use the hooked end of the wheel nut
wrench extension as a wrench if
the wing bolt is hard to loosen.
Then take the spare tire out of the
cargo area.WING BOLT

8. Use the extension and the wheelnut wrench as shown to raise the
vehicle until the flat tire is off the
ground.
9. Remove the wheel nuts, then remove the flat tire. Handle the
wheel nuts carefully; they may be
hot from driving. Place the flat tire
on the ground with the outside
surface facing up.
10. Before mounting the spare tire, wipe any dirt off the mounting
surface of the wheel and hub with
a clean cloth. Wipe the hub
carefully; it may be hot from
driving. 11. Put on the spare tire. Put the
wheel nuts back on finger-tight,
then tighten them in a crisscross
pattern with the wheel nut wrench
until the wheel is firmly against the
hub. Do not try to tighten the
wheel nuts fully.

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

Brake System Indicator
(Red)U.S. CanadaThe brake system indicator (red)
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 fully release the parking
brake.
If the brake system indicator (red)
comes on while driving, the brake
fluid level is probably low. Press
lightly on the brake pedal to see if it
feels normal. If it does, check the
brake fluid level the next time you
stop at a service station (see page
429).
You will also see a‘‘BRAKE FLUID
LOW ’’message on the multi-
information display (see page 79). If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for 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
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 79). Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see
Emergency
Towing on page 475).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
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 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.
