Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
A CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire.
To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in PARK
(P) or shift a manual
transmission to FIRST
(1) or
REVERSE (R).
CAUTIQN: iContinued) .~
3. If you have a four-wheel-drive vehicle
with a manual transfer case shift lever,
be sure the transfer case is in a drive
gear
-- not in NEUTRAL (N).
4. Turn off the engine.
5. Put the wheel blocks at the front and
rear
of the tire farthest away from the
one being changed. That would be the
tire on the other side of the vehicle,
at
the opposite end.

~~~ ~~~ NOTICE:
When
the compact spare is installed, don’t take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And
don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transmission or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above 35 mph
(55 kmh) as shown
on the speedometer.

Automatic Transmission Fluid
Operating the engine with the air cleaner off can
cause you or others
to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine
backfires.
If it isn't there, and the engine
backfires, you could be burned. Don't drive with
it
off, and be careful working on the engine with
the air cleaner
off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which
will damage it. Always
have the air cleaner
in place when you're driving.
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid
and filter every 50.000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi. police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See "Scheduled Maintenance Services"
in the Index.

3. Check both sides of the dipstick. and read the lower
level.
The fluid level must be in the COLD area for a
cold check or in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range. push the
dipstick back
in all the way: then flip the handle
down to lock the dipstick in place.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See "Recommended
Fluids and Lubricants"
in the Index.
Add fluid
only after checking the transmission fluid
HOT. (A COLD check is used only as a reference.) If
the fluid level is low, add only enough of the proper
tluid
to bring the 1wel up to the HOT area for a hot
check.
It doesn't take much fluid. generally less than
one pint (0.5 L). Ih f o\*erfi//.
NOTICE:
We recomnlend you use only fluid labeled
DEXRON@-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused
by fluid other than DEXRON-111
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under "How to Check."
When the correct fluid level is obtained. push the
dipstick back
in all the way; then flip the handle
down
to lock the dipstick in place.
