Electronic Shift-On-the-Fly (ESOF)
• Easy-to-userotarycontrolswitchmounted
in the instrument panel is used to select
drive settings, eliminating the need to stop
and back up to unlock the front hubs
• Electricmotorshiftsthetransfercaseinto

• Fronthublockselectorsaremarkedwith
AUTO and LOCK. Manual override capability
lets the driver manually LOCK hubs if
preferred, but the Continuous Vacuum
Hublock (CVH) design engages the front
hubs, providing virtually silent operation
• CVHsystemoptimizesfuelefficiency
because all front driveline components
are disconnected at the wheels when the
system is in 2WD operation
NOTE: Both of these 4x4 systems are
“part-time"systemsdesignedtoprovide
enhanced traction on reduced traction
surfaces only. Operating on normal or high-
traction surfaces can result in transfer case
damage, increased tire wear and decreased
fuel efficiency.

by serious off-roaders and those working at

• Toengagethefrontaxle,theoperatormust
stop, exit the vehicle and rotate both hublock
selector knobs to the LOCK position, then
the desired drive range is selected on the
transfer case
• Floor-mountedtransfercaseshiftleverisused
to move between available drive settings: 2H
(2WD), 4H (4x4 High), N (Neutral) and 4L
(4x4 Low)
• WhenthehublocksarereturnedtotheFREE
position, the drive axle components do not
rotate while driving, which reduces wear and
frictional drag
NOTE: The vehicle should not be operated
in 4H or 4L with the manual-locking hubs
set in the FREE position as this could result
in damage to certain driveline components.
Operate the vehicle in 4H or 4L only with
manual-locking hubs set in the LOCK position.
