2010 JEEP GRAND CHEROKEE cruise control

Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fifth gear for
3.6L and 3.0L Diesel engine, fourth and fifth
gears for 5.7L engine). The transmission will
automatically shift to Overdrive, if the following
conditions are present:
•the shift lever is in DRIVE;
• the engine coolant has reached normal op-
erating temperature;
• vehicle speed is above approximately
30 mph (48 km/h);
• the TOW/HAUL switch has not been acti-
vated;
• transmission has reached normal operating
temperature.
NOTE:
If the vehicle is started in extremely cold
temperatures, the transmission may not
shift into Overdrive and will automatically
select the most desirable gear for operation
at this temperature. Normal operation will
resume when the transmission fluid tem-
perature has risen to a suitable level. Refer to the “Note” under “Torque Converter
Clutch” in this section.
During cold temperature operation you may
notice delayed upshifts, depending on en-
gine and transmission temperature. This
feature improves the warm-up time of the
engine and transmission.
If the transmission temperature gets ex-
tremely hot, the transmission will automati-
cally select the most desirable gear for op-
eration at this temperature. If the
transmission temperature becomes hot
enough, the “TRANSMISSION OVER TEMP”
message may display, and the transmission
may downshift out of Overdrive until the
transmission cools down. After cool down,
the transmission will resume normal opera-
tion.
The transmission will downshift from Overdrive,
to the most desirable gear, if the accelerator
pedal is fully pressed at vehicle speeds above
approximately 35 mph (56 km/h).
When to Use TOW/HAUL Mode –
If Equipped
When driving in hilly areas, towing a trailer,
carrying a heavy load, etc., and frequent trans-
mission shifting occurs, press the TOW/HAUL
switch. This will improve performance and re-
duce the potential for transmission overheating
or failure due to excessive shifting. When oper-
ating in TOW/HAUL mode, the transmission will
shift into direct gear and Overdrive will be
enabled under steady cruise conditions.
