2010 JEEP GRAND CHEROKEE brake

Shifting Procedures
4WD HI To 4WD LOW
• With the vehicle at speeds of 0 to 3 mph(0 to 5 km/h), key ON or engine
running, shift the transmission into
NEUTRAL, and raise the transfer case
T-handle. The “4WD LOW” indicator
light in the instrument cluster will
begin to flash and remain on solid
when the shift is complete. Release the
T-handle.
• Shifting into or out of 4WD LOW is possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may
be required for clutch teeth alignment
and shift completion to occur. The
preferred method is with the vehicle
rolling 0 to 3 mph (0 to 5 km/h). If the
vehicle is moving faster than 3 mph
(5 km/h), the transfer case will not
allow the shift.
4WD LOW To 4WD HI
• With the vehicle at speeds of 0 to 3 mph(0 to 5 km/h), key ON or engine
running, shift the transmission into
NEUTRAL, and raise the transfer case
T-handle. The “4WD LOW” indicator
light in the instrument cluster will flash
and go out when the shift is complete.
Release the T-handle.
NEUTRAL Shift Procedure
• Key ON, engine off.
• Vehicle stopped, with foot on brake.
• Place the transmission into NEUTRAL.
• Hold down the NEUTRAL “pin” switch
(with a pen, etc.) for four seconds until
the LED light by the switch starts to
blink indicating shift in progress. The
light will stop blinking (stay on solid)
when the NEUTRAL shift is complete. A
“4WD SYSTEM IN NEUTRAL” message
will display on the Electronic Vehicle
Information Center (EVIC).
• Repeat these Steps to shift out of NEUTRAL.

INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Program (ESP) Indicator Light
• If this indicator light flashes during acceleration, apply as little throttle as possible. Whiledriving, ease up on the accelerator. Adapt your speed and driving to the prevailing road
conditions. To improve the vehicle's traction when starting off in deep snow, sand or
gravel, it may be desirable to switch the ESP system off.
- Tire Pressure Monitoring System (TPMS) Light
• A Tire Pressure Monitoring Light and a “low tire” message will display in your instrumentcluster along with an audible chime if one or more of your vehicle’s four road tires are
significantly under-inflated.
• Check the inflation pressure of each tire and inflate to the recommended pressure for your vehicle. The tire pressures recommended for your vehicle are found on the “Tire and
Loading Information” label located on the driver’s side door opening. The TPMS light
should not be used as a tire pressure gauge when adjusting your tire pressure.
• It is recommended that you check the tire pressure in the morning when tires are cool; inflate each tire to the recommended pressure for your vehicle. The light will turn off
after your vehicle’s tire pressures are properly inflated and the pressure has been
recognized. The vehicle may need to be driven for up to 20 minutes above 15 mph
(25 km/h) before the light will turn off.
• Temperature changes can affect tire pressure, causing the TPMS light to turn on. Tire pressures will also increase as the vehicle is driven – this is normal and you should not
adjust for this increased pressure.
• Driving on under-inflated tires reduces your vehicle’s fuel efficiency and tire tread life. If a spare tire is in use on the vehicle, the TPMS light may turn on.
- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or theparking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an Anti-Lock
Brake System problem.
• We recommend you drive to the nearest Service Center and have the vehicle serviced immediately.

EVENT DATA RECORDER (EDR)
• This vehicle is equipped with an Event Data Recorder (EDR). The main purpose of an EDRis to record, in certain crash or near crash-like situations, such as an air bag deployment
or hitting a road obstacle, data that will assist in understanding how a vehicle's systems
performed. The EDR is designed to record data related to vehicle dynamics and safety
systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
• This data can help provide a better understanding of the circumstances in which a crash and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash
situation occurs; no data is recorded by the EDR under normal driving conditions and no
personal data (e.g., name, gender, age, and crash location) is recorded. However, other
parties, such as law enforcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a crash investigation.
• To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such
as law enforcement, that have the special equipment, can read the information if they
have access to the vehicle or the EDR.
