If a front tire fails, the flat tire creates
a drag that pulls the vehicle toward
that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, and then gently brake to a
stop, well off the road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in
a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash. Never
attempt to re-inflate a tire that has
been driven on while severely
underinflated or flat. Have your(Continued)

dealer or an authorized tire service
center repair or replace the flat tire
as soon as possible.
{Warning
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 flat
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
flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard Warning
Flashers 0155.
{Warning
Changing a tire can be dangerous.
The vehicle can slip off the jack and
roll over or fall causing injury or
death. Find a level place to change
the tire. To help prevent the vehicle
from moving:
1. Set the parking brake firmly.
2. Put an automatictransmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle
is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks, if equipped, on both sides of
the tire at the opposite corner
of the tire being changed.
