SEATS AND RESTRAINTS 89
{Warning
A child in a rear-facing child
restraint can be seriously injured or
killed if the front outboard
passenger frontal airbag inflates.
This is because the back of the
rear-facing child restraint would be
very close to the inflating airbag.
A child in a forward-facing child
restraint can be seriously injured or
killed if the front outboard
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are off.
Secure rear-facing child restraints
in a rear seat, even if the airbag(s)
are off. If you secure a(Continued)
Warning (Continued)
forward-facing child restraint in the
front outboard passenger seat,
always move the seat as far back as
it will go. It is better to secure the
child restraint in a rear seat.
SeePassenger Sensing System 066
for additional information.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 078 for top
tether anchor locations.
Do not secure a child seat in a
position without a top tether anchor if
a national or local law requires that
the top tether be anchored, or if the
instructions that come with the child
restraint say that the top tether must
be anchored.
In Canada, the law requires that
forward-facing child restraints have a
top tether, and that the tether be
attached. When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:
1. Move the seat as far back as it will go before securing the
forward-facing child restraint.
Move the seat upward or the
seatback to an upright position,
if needed, to get a tight
installation of the child restraint.
When the passenger sensing
system has turned off the front
outboard passenger frontal and
knee airbag, the off indicator on
the passenger airbag status
indicator should light and stay lit
when you start the vehicle. See
Passenger Airbag Status Indicator
0114.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle seat belt through or

Caution
The manual park release is not
intended to be used for towing.
Damage may result from using the
manual park release in this way.
The repairs would not be covered
by the vehicle warranty.
The manual park release can be used
to shift the vehicle into N (Neutral)
when the engine is not running.
Pulling the manual park release while
the vehicle is on or turning the
ignition on while the manual park
release is pulled, will cause a DIC
message to display.
To place the vehicle in N (Neutral)
using the manual park release: 1. Ensure the vehicle is on level ground and set the parking
brake.
2. Turn the vehicle off.
3. Use a flat-bladed tool to remove the interior trim panel on the
center console to the right of the
accelerator pedal.
4. Ensure more than one minute has elapsed since Step 2. Apply
the brake pedal.5. Pull the manual park release
lever 90° to its latching position.
6. With the brake pedal released, place the ignition in ACC/
ACCESSORY. Then apply the
brake pedal and release the
parking brake.
7. Ensure there are no loose objects in the area that could bump the
manual park release lever.
To return the vehicle to P (Park) using
the manual park release: 1. Bring the vehicle to a complete stop.

death. Never run the engine in an
enclosed area that has no fresh air
ventilation. For more information,
seeEngine Exhaust 0181.
{Warning
Overinflating a tire could cause the
tire to rupture and you or others
could be injured. Be sure to read
and follow the tire sealant and
compressor kit instructions and
inflate the tire to its recommended
pressure. Do not exceed the
recommended pressure.
{Warning
Storing the tire sealant and
compressor kit or other equipment
in the passenger compartment of
the vehicle could cause injury. In a
(Continued)
Warning (Continued)
sudden stop or collision, loose
equipment could strike someone.
Store the tire sealant and
compressor kit in its original
location.
If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire or tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor can
be used to temporarily seal punctures
up to 6 mm (0.25 in) in the tread area
of the tire. It can also be used to
inflate an underinflated tire.
If the tire has been separated from the
wheel, has damaged sidewalls, or has
a large puncture, the tire is too
severely damaged for the tire sealant
and compressor kit to be effective.
Read and follow all of the tire sealant
and compressor kit instructions.
The kit includes:
1. Sealant Canister Inlet Valve
2. Sealant/Air Hose
3. Base of Sealant Canister
4. Tire Sealant Canister
5. On/Off Button
6. Slot on Top of Compressor
7. Pressure Deflation Button
8. Pressure Gauge

5. Slide the base of the tire sealantcanister (3) into the slot on the
top of the compressor (6) to hold
it upright.
Make sure the tire valve stem is
positioned close to the ground so
the hose will reach it.
6. Remove the valve stem cap from the flat tire by turning it
counterclockwise.7. Attach the sealant/air hose (2) tothe tire valve stem by turning it
clockwise until tight.
8. Plug the power plug (9) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets 0104.
Do not pinch the power plug
cord in the door or window.
9. Start the vehicle. The vehicle must be running while using the
air compressor.
10. Press the on/off button (5) to turn the tire sealant and
compressor kit on. The compressor will inject
sealant and air into the tire.
The pressure gauge (8) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
11. Inflate the tire to the recommended inflation pressure
using the pressure gauge (8). The
recommended inflation pressure
can be found on the Tire and
Loading Information label. See
Tire Pressure 0279.
The pressure gauge (8) may read
higher than the actual tire
pressure while the compressor is
on. Turn the compressor off to
get an accurate pressure reading.
The compressor may be turned
on/off until the correct pressure
is reached.

3. Place the compressor on theground near the flat tire.
Make sure the tire valve stem is
positioned close to the ground so
the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise.
5. Attach the air only hose (10) to the tire valve stem by turning it
clockwise until tight.
6. Plug the power plug (9) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See Power Outlets 0104.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Press the on/off button (5) to turn the tire sealant and
compressor kit on.
The compressor will inflate the
tire with air only. 9. Inflate the tire to the
recommended inflation pressure
using the pressure gauge (8). The
recommended inflation pressure
can be found on the Tire and
Loading Information label. See
Tire Pressure 0279.
The pressure gauge (8) may read
higher than the actual tire
pressure while the compressor is
on. Turn the compressor off to
get an accurate pressure reading.
The compressor may be turned
on/off until the correct pressure
is reached.
Caution
If the recommended pressure
cannot be reached after
approximately 25 minutes, the
vehicle should not be driven farther.
The tire is too severely damaged
and the tire sealant and compressor
kit cannot inflate the tire. Remove
the power plug from the accessory
power outlet and unscrew the
inflating hose from the tire valve. 10. Press the on/off button (5) to
turn the tire sealant and
compressor kit off.
Be careful while handling the
compressor as it could be warm
after usage.
11. Unplug the power plug (9) from the accessory power outlet in the
vehicle.
12. Turn the air only hose (10) counterclockwise to remove it
from the tire valve stem.
13. Replace the tire valve stem cap.
14. Return the air only hose (10) and power plug (9) back to their
original storage location.
15. Return the equipment to its original storage location in the
vehicle.
The tire sealant and compressor kit
has accessory adapters located in a
compartment on the bottom of its
housing that can be used to inflate air
mattresses, balls, etc.
