never shift above third gear, but can shift down
to 2 (second) or 1 (first), when needed.
NOTE:
• If you pull and hold (not tap) the shift lever
to the left (-), the transmission will down-
shift to the lowest gear that can be at-
tained without overrevving the engine.
The display will show the gear the vehicle
is in and will limit the top gear to the one
displayed.
• If you push and hold (not tap) the shift
lever to the right (+), the transmission will
exit the gear limiting mode and shift to the
appropriate gear. The display will read
D .
3.6L and 3.0L Diesel Engine
When in the DRIVE position, the first tap to the
left (-) will shift down one gear and will display
that gear. For example, if you are in DRIVE and
are in fifth gear, when you tap the shift lever one
time to the left (-), the transmission will down-
shift to fourth gear and the display will show 4.
Another tap to the left (-) will shift the transmis-
sion into third gear.
5.7L Engine
On vehicles equipped with the 5.7L engine,
use of ERS (or TOW/HAUL mode) also enables
an additional underdrive gear which is not
normally used during through-gear accelera-
tions. This additional gear improves vehicle
performance and cooling capability when tow-
ing a trailer on certain grades. ERS 1, 2, and 3
are underdrive gears; ERS 4 is direct drive. ERS
5 (Overdrive) is the same as the normal 4th
gear. When in the DRIVE position in first through
fourth gear, the first tap to the left (-) will display
the ERS designation for the current gear (the
transmission will not downshift). For example, if
you are in DRIVE and are in third (direct) gear,
when you tap the shift lever one time to the left
(-), the display will show 4 (ERS 4 is direct
gear). Another tap to the left (-) will shift the
transmission down to ERS 3 (the added under-
drive gear). When in the DRIVE position in fifth
gear, the first tap to the left (-) will downshift the
transmission and display 5 (ERS 5 is the same
as normal fourth gear). Another tap to the left (-)
will shift the transmission down to ERS 4 (direct
gear).
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid.

NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), move
the shift lever to the left "D(-)" and hold it
there. The transmission will shift to the
range from which the vehicle can best be
slowed down.
