Jeep 2004 Wrangler - Manual (Page 164)

• Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
• Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
• When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
• Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
• During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
• Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.
• When “rocking” a stuck vehicle by shifting between a
forward gear and reverse, do not spin wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• The manual transmission may be equipped with a
“Reverse Blocker” to prevent inadvertent shifts from
5th gear to Reverse. If you experience difficulty shift-
ing into “Reverse”, make sure that you are not inad-
vertently moving the shift lever toward 5th gear when
shifting into “Reverse.”
