parking brake JEEP GRAND CHEROKEE 2017 WK2 / 4.G User Guide

WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is re-
sponsible for maintaining a safe vehicle speed.
Selec Speed Control (SSC) — If Equipped
SSC is intended for off road driving in 4WD Low Range
only. SSC maintains vehicle speed by actively controlling
engine torque and brakes.
SSC has three states:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activationconditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling ve- hicle speed).
Enabling SSC
SSC is enabled by pushing the SSC switch, but the follow-
ing conditions must also be met to enable SSC:
• Driveline is in 4WD Low Range. •
Vehicle speed is below 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed.
• Driver is not applying throttle.
Activating SSC
Once SSC is enabled it will activate automatically once the
following conditions are met:
• Driver releases throttle.
• Driver releases brake.
• Transmission is in any selection other than P.
• Vehicle speed is below 20 mph (32 km/h).
The set speed for SSC is selectable by the driver, and can be
adjusted by using the gear shift +/-. Additionally, the SSC
set speed may be reduced when climbing a grade and the
level of set speed reduction depends on the magnitude of
grade. The following summarizes the SSC set speeds:
SSC Target Set Speeds
• 1st = .6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
5
SAFETY 193

•3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
• REVERSE = .6 mph (1 km/h)
• NEUTRAL = 1.2 mph (2 km/h)
• PARK = SSC remains enabled but not active
NOTE:
• During SSC the +/- shifter input is used for SSC target
speed selection but will not affect the gear chosen by the
transmission. While actively controlling SSC the trans-
mission will shift appropriately for the driver-selected
set speed and corresponding driving conditions.
• SSC performance is influenced by the Terrain Select
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness. Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
•
Driver overrides SSC set speed with throttle or brake
application.
• Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h).
• Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
• The driver pushes the SSC switch.
• The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.

interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

STARTING PROCEDURES — GASOLINE ENGINES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•Before exiting a vehicle, always shift the automatic
transmission into PARK and apply the parking
brake. Always make sure the keyless ignition node is
in the “OFF” mode, remove the key fob from the
vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could

operate power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Normal Starting
To Turn On The Engine Using The ENGINE START/
STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
3. The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will disengage
automatically after 10 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.6
STARTING AND OPERATING 265

While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.
The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. For the recommended
viscosity and quality grades, refer to “Fluids And Lubri-
cants” inTechnical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as an indication of difficulty. Please check your
oil level with the engine oil indicator often during the
break in period. Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
PARK position.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, press the park brake pedal a second time
and let your foot up as you feel the brake disengage.
Parking Brake

STARTING AND OPERATING 271

When the parking brake is applied with the ignition switch
in the ON position, the “Brake” Warning Light in the
instrument cluster will illuminate.
NOTE:
•When the parking brake is applied and the transmission
is placed in gear, the “Brake” Warning Light will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, remove
the key fob from the vehicle and lock the vehicle.
• Do not leave the key fob in or near the vehicle or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.

WARNING!(Continued)
•Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake” Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your

foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK, and
turn the ignition OFF. When the ignition is in the
OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to

mission gear selector.
• Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
• Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Ignition Park Interlock
This vehicle is equipped with a Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF mode.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed. The brake pedal must
also be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehicle’s
overall fuel economy during normal driving conditions.
Push the “ECO” switch in the center stack of the instru-
ment panel to activate or disable ECO mode. An amber
274 STARTING AND OPERATING

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 especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
When exiting the vehicle, always:
• Apply the parking brake, •
Shift the transmission into PARK,
• Turn the ignition OFF and,
• Remove the key fob from the vehicle.
NOTE: On four-wheel drive vehicles be sure that the
transfer case is in a drive position.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before leaving the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
