Jeep Grand Cherokee 2013 Operating Information Manual page 235

Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fifth gear). The
transmission will automatically shift into Over-
drive if the following conditions are present:
• the shift lever is in the DRIVE position,
• vehicle speed is sufficiently high, and
• the driver is not heavily pressing the
accelerator.
Six-Speed Automatic Transmission
(5.7L Engine) — If Equipped
The shift lever position display (located in the
instrument cluster) indicates the transmission
gear range. You must press the brake pedal to
move the shift lever out of PARK (refer to
"Brake/Transmission Shift Interlock System" in
this section). To drive, move the shift lever from
PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission pro-
vides a precise shift schedule. The transmission
electronics are self-calibrating; therefore, the
first few shifts on a new vehicle may be some-
what abrupt. This is a normal condition, and
precision shifts will develop within a few hun-
dred kilometers.
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when moving the shift lever
between these gears.
The transmission shift lever has only PARK,
REVERSE, NEUTRAL, and DRIVE shift posi-
tions. Manual downshifts can be made using
the Electronic Range Select (ERS) shift control
(refer to "Electronic Range Select (ERS) Opera-
tion" in this section). Moving the shift lever to the
left or right (-/+) while in the DRIVE position will
select the highest available transmission gear,
and will display that gear in the instrument
cluster as 6, 5, 4, 3, 2, 1.

Gear Ranges
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range.
NOTE:
• After selecting any gear range, wait a
moment to allow the selected gear to
engage before accelerating. This is espe-
cially important when the engine is cold.
