Jeep 2006 Wrangler - Manual (Page 234)

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel cap
(gas cap). A poorly fitting cap could let impurities
into the fuel system. Also, a poorly fitting after-
market cap can cause the MIL (Malfunction Indica-
tor Light) to illuminate, due to fuel vapors escaping
from the system.
• Turn the engine off.
• Rotate the fuel cap to the left to remove.
• To replace the cap, insert it into the filler neck and
tighten the cap about 1/4 turn until you hear two
clicks. This is an indication that the cap is properly
tightened.
• Make sure that the fuel cap tether strap is not caught
under the fuel cap.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE: When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
