/1 CAUTION:
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.
When you put the cap back on, turn it to the right
(clockwise)
until you hear a clicking sound. Make sure
you fully install the cap.
NOTICE:
If you need a new cap, be sure to get the right
type.
Your dealer can get one for you. If you get
the wrong type, it may not
fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Be careful not
to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index.

How to Add Fluid

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

HOT area for a hot check. It
doesn’t take much fluid, generally less than one pint
(0.5 L). Don ’t ove@ZZ.
NOTICE:
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-111
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under
“HOW to Check.”
