If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially
if you maintain the tires properly.
SeeTires on page 5-35.Ifair
goes out of a tire, It is much more
likely to leak out slowly. But if
you should ever have a blowout,
here are a few tips about what
to expect and what to do:
If a front tire fails, the at tire will
create a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel rmly. Steer to
maintain lane position, and then
gently brake to a stop well out of
the traffic lane.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction youwould use in a skid. In any rear
blowout, remove your foot from the
accelerator pedal. Get the vehicle
under control by steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place and stopping.
1. Turn on the hazard warning
ashers. SeeHazard Warning
Flashers on page 3-5.
2. Park the vehicle. Set the parking
brake rmly and put the shift
lever in P (Park).
3. Turn off the engine.
4. Inspect the at tire.{CAUTION
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a
at tire. If it is used for anything
else, you or others could be badly
injured or killed if the vehicle slips
off the jack. If a jack is provided
with the vehicle, only use it for
changing a at tire.
This vehicle may come with a jack
and spare tire or a tire sealant
and compressor kit. To use the jack
and spare tire, seeChanging a
Flat Tire on page 5-69. To use the
tire sealant and compressor kit,
seeTire Sealant and Compressor
Kit on page 5-56.

{CAUTION
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, seeEngine
Exhaust on page 2-30.
{CAUTION
Over-inating 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
inate the tire to its recommended
pressure. Do not exceed the
recommended pressure.
{CAUTION
Storing the tire sealant and
compressor kit or other equipment
in the passenger compartment of
the vehicle could cause injury. In a
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, 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
14inch (6 mm)
in the tread area of the tire. It can
also be used to inate an under
inated 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. SeeRoadside Assistance
Program on page 7-6.
Read and follow all of the tire
sealant and compressor kit
instructions.

Service and Appearance Care 5-61

When using the tire sealant and
compressor kit during cold
temperatures, warm the kit in a
heated environment for 5 minutes.
This will help to inate the tire faster.
Always do a safety check rst.
SeeIf a Tire Goes Flat on
page 5-55. Do not remove any
objects that have penetrated the tire.
1. Remove the tire sealant and
compressor kit from its storage
location. SeeTire Sealant
and Compressor Kit Storage
on page 5-68.
2. Unwrap the sealant/air hose (F)
and the power plug (H).
3. Place the kit on the ground.
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 at tire by turning it
counterclockwise.
5. Attach the sealant/air hose (F)
onto the tire valve stem. Turn
it clockwise until it is tight.
6. Plug the power plug (H) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
SeeAccessory Power Outlet(s)
on page 3-20.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
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. Turn the selector switch (A)
counterclockwise to the
Sealant + Air position.
9. Press the on/off (B) button
to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gage (C) 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
inates with air only.
