Never let passengers ride in a vehicle that is
being towed.
Never tow faster than safe
or posted speeds.
Never tow with damaged parts not
fully secured.
Never get under your vehicle after it has
been lifted by the tow truck.
Always use separate safety chains on each
side when towing a vehicle.
For pickups (except cab chassis models),
use T-hooks on front of vehicle, J-hooks
on rear.
For cab chassis models, use J-hooks on
front and rear of vehicle.
I A CAUTION:
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle.
When your vehicle
is being towed, have the ignition
key in the OFF position. The steering wheel should be
clamped in a straight-ahead position,
with a clamping
device designed
for towing service. Do not use the
vehicle’s steering column lock for this. The transmission
and transfer case,
if you have one, should be in
NEUTRAL (N) and the parking brake released.
Don’t have your vehicle towed
on the drive wheels
unless
you must. If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later
in this section or your transmission will
be damaged.
If these limitations must be exceeded, then
the drive wheels have to be supported on
a dolly.

Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials
away from gasoline.
While refueling,
hang the
cap inside the fuel door.
To take off the. cap, turn it slowly to the left
(counterclockwise).
/i CAUTIP
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on
you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap
all the way.

How to Add Fluid
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. 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
fluid
to bring the level up to the HOT area for a hot
check. It doesn’t take much fluid, generally less than a
pint
(-0.5 L). Don’t overjill. We recommend you use only
fluid labeled DEXRON@-111, because fluid with that
label is made especially for your automatic transmission.
Damage caused by fluid other than DEXRON-I11 is
not
covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How to Check.”
0 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.
