2012 JEEP GRAND CHEROKEE reset

SPORT
This mode alters the transmission’s automatic shift
schedule for sportier driving. Upshift speeds are in-
creased to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console. Refer to “Selec-Terrain” in “Starting And
Operating” for further information.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. The Malfunction Indicator Light (MIL)may be illuminated. Limp Home Mode allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
388 STARTING AND OPERATING

NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing 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.
When to Use TOW Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, select TOW mode, using the rotary switch on the
center console. Selecting TOW mode will improve per-
formance and reduce the potential for transmission over-
heating or failure due to excessive shifting. Refer to
“Selec-Terrain” in “Starting And Operating” for further
information.
AUTOSTICK
AutoStickis a driver-interactive transmission feature
that offers manual gear shifting to provide you with more
control of the vehicle. AutoStickallows you to maximize
engine braking, eliminate undesirable upshifts and
downshifts, and improve overall vehicle performance.

SELEC-TRACK™ — IF EQUIPPED
Description
Selec-Track™ combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.Selec-Track™ consists of the following positions:
•Sport– Dry weather, on-road calibration. Performance
based tuning that provides a rear wheel drive feel but
with improved handling and acceleration over a two-
wheel drive vehicle. The customer has the option of
going to partial ESC. The active suspension system
will be in Semi Firm mode, and a green flag will light
up in the instrument cluster. The transmission will
provide a more aggressive shifting pattern (Refer to
“AutoStick” in “Starting And Operating” for further
information). This feature will reset to AUTO on an
ignition cycle.
•Snow– Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage.

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. It is even more important to
look for gasoline without MMT in Canada, because MMT

CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
Regular automatic transmission fluid level checks are not
required. For this reason the dipstick is omitted.
If you notice fluid loss or transmission slippage or
malfunction, have your authorized dealer check the
transmission fluid level.
CAUTION!
The fluid level is preset at the factory and does not
require adjustment under normal operating condi-
tions. If a transmission fluid leak occurs, visit your
authorized dealer immediately. Severe damage to the
transmission may occur. Your authorized dealer has
the proper tools to accurately adjust the fluid level.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle.

MAINTENANCE SCHEDULES
The Scheduled Maintenance services listed in this
manual must be done at the times or mileages specified
to protect your vehicle warranty and ensure the best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving. Inspection and service should also be done
anytime a malfunction is suspected.
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).NOTE:•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicle’s
oil if it has been 6 months since your last oil change
even if the oil change indicator message is NOT
illuminated.
•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
