2017 JEEP GRAND CHEROKEE change time

Diesel Engines
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• Warm up the engine before placing it underload.
• Do not operate the engine at idle for pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and tempera- ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer
towing or no load operation will extend the
time before the engine is at full efficiency.
Reduced fuel economy and power may be
seen at this time. The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. The
recommended viscosity and quality grades
are shown under “Fluids And Lubricants” in
"Technical Specifications” in this manual.
NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
SRT Engines
The following tips will be helpful in obtaining
optimum performance and maximum dura-
bility for your new SRT Vehicle.
Despite modern technology and World Class
manufacturing methods, the moving parts of
the vehicle must still wear in with each other.
This wearing in occurs mainly during the first
500 miles (805 km) and continues through
the first oil change interval.
It is recommended for the operator to observe
the following driving behaviors during the
new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle
for an extended period of time.
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid ac-
celeration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.
100 to 300 miles (161 to 483 km):
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid ac-
celeration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.
• Drive with the engine speed less than 5,000 RPM.
• Maintain vehicle speed below 70 mph (112 km/h) and observe local speed
limits.
STARTING AND OPERATING

(40 km/h) the vehicle height will be auto-
matically lowered to OR1. Refer to “Driv-
ing Tips” in “Starting And Operating” for
further information.
• Aero Mode (Lowers the vehicle approxi-
mately 0.6 inches (15 mm) – This position
provides improved aerodynamics by lower-
ing the vehicle. The vehicle will automati-
cally enter Aero Mode when the vehicle
speed remains between 52 mph (83 km/h)
and 56 mph (90 km/h) for greater than
20 seconds or if the vehicle speed exceeds
56 mph (90 km/h). The vehicle will return
to NRH from Aero Mode if the vehicle
speed remains between 20 mph (32 km/h)
and 25 mph (40 km/h) for greater than
20 seconds or if the vehicle speed falls
below 20 mph (32 km/h). The vehicle will
enter Aero Mode, regardless of vehicle
speed if the vehicle is in “SPORT” mode.
• Entry/Exit Mode (Lowers the vehicle approxi-
mately 1.6 inces (40 mm) – This position
lowers the vehicle for easier passenger
entry and exit as well as lowering the rear
of the vehicle for easier loading and un-
loading of cargo. To enter Entry/Exit Mode,
push the “DOWN” button once from (NRH) while the vehicle speed is below
25 mph (40 km/h). Once the vehicle
speed goes below 15 mph (24 km/h) the
vehicle height will begin to lower. If the
vehicle speed remains between 15 mph
(24 km/h) and 25 mph (40 km/h) for
greater than 60 seconds, or the vehicle
speed exceeds 25 mph (40 km/h) the
Entry/Exit Mode change will be cancelled.
To exit Entry/Exit Mode, press the “Up”
button once while in Entry/Exit Mode or
drive the vehicle over 15 mph (24 km/h).
NOTE:
Automatic lowering of the vehicle into Entry/
Exit Mode can be enabled through the
Uconnect Touch-Screen Radio. If this feature
is enabled, the vehicle will only lower if the
gear selector is in "PARK", the terrain switch
is in "AUTO", the transfer-case is in "AUTO”
and the vehicle level should be either in
Normal or Aero Mode. The Vehicle will not
automatically lower if the air suspension level
is in Off Rd 2 or Off Rd 1. If the vehicle is
equipped with Intrusion Theft Module (ITM),
the lowering will be suppressed when the
ignition is switched OFF and the door is open
to prevent setting the alarm off. The Selec-Terrain switch will automatically
change the vehicle to the proper height based
on the position of the Selec-Terrain switch.
The height can be changed from the default
Selec-Terrain setting by normal use of the air
suspension buttons. Refer to “Selec-Terrain”
in “Starting And Operating” for further infor-
mation.
The system requires that the engine be run-
ning for all changes. When lowering the ve-
hicle all of the doors, including the liftgate,
must be closed. If a door is opened at any
time while the vehicle is lowering the change
will not be completed until the open door(s) is
closed.
The Quadra-Lift air suspension system uses a
lifting and lowering pattern which keeps the
headlights from incorrectly shining into on-
coming traffic. When raising the vehicle, the
rear of the vehicle will move up first and then
the front. When lowering the vehicle, the
front will move down first and then the rear.

achieve. When raising, if multiple indicator
lamps are flashing on the “Up” button, the
highest flashing indicator lamp is the posi-
tion the system is working to achieve. When
lowering, if multiple indicators are flashing
on the "Up" button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pushing the “UP” button once will move the
suspension one position higher from the cur-
rent position, assuming all conditions are
met (i.e. engine running, speed below thresh-
old, etc). The “UP” button can be pushed
multiple times, each push will raise the re-
quested level by one position up to a maxi-
mum position of OR2 or the highest position
allowed based on current conditions (i.e. ve-
hicle speed, etc).
Pushing the “DOWN” button once will move
the suspension one position lower from the
current level, assuming all conditions are met
(i.e. engine running, doors closed, speed be-
low threshold, etc). The “DOWN” button can
be pressed multiple times. Each push will
lower the requested level by one positiondown to a minimum of Park Mode or the
lowest position allowed based on current con-
ditions (i.e. vehicle speed, etc.)
Automatic height changes will occur based
on vehicle speed and the current vehicle
height. The indicator lamps and instrument
cluster display messages will operate the
same for automatic changes and user re-
quested changes.
• Off-Road 2 (OR2) – Indicator lamps 4, 5,
and 6 will be illuminated when the vehicle
is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 4 and 5 will be illuminated when the vehicle is in
OR1.
• Normal Ride Height (NRH) – Indicator lamp 4 will be illuminated when the ve-
hicle is in this position.
• Entry/Exit Mode – Indicator lamp 3 will be illuminated when the vehicle is in Entry/
Exit Mode. If Entry/Exit Mode is requested
while vehicle speed is between 15 mph
(24 km/h) and 25 mph (40 km/h), indica-
tor lamp 4 will remain on solid and indi-
cator lamp 3 will flash as the system waits
for the vehicle to reduce speed. If vehicle speed is reduced to, and kept below,
15 mph (24 km/h) indicator lamp 4 will
turn off and indicator lamp 3 will flash
until Entry/Exit Mode is achieved at which
point indicator lamp 3 will go solid. If
during the height change to Entry/Exit
Mode, the vehicle speed exceeds 15 mph
(24 km/h), the height change will be
paused until the vehicle speed either goes
below 15 mph (24 km/h) and the height
change continues to Entry/Exit Mode, or
exceeds 25 mph (40 km/h) and the ve-
hicle height will return to NRH. Entry/Exit
Mode may be selected while the vehicle is
not moving provided that the engine is still
running and all doors remain closed.
• Transport Mode - No indicator lamps will be illuminated. Customer driving will dis-
able Transport Mode.
• Tire/Jack Mode - indicator lamps 3 and 6 will be illuminated. Customer driving
will disable Tire/Jack Mode.
• Wheel Alignment Mode - indicator lamps 3 and 4 will be illuminated. Customer
driving will disable Wheel Alignment
Mode.

SELEC-TERRAIN — IF
EQUIPPED
Selec-Terrain Mode Selection
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains. Selec-Terrain consists of the following posi-
tions:
•
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 cer-
tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage. If equipped with air suspension,
the default ride height for Snow is Normal
Ride Height (NRH).
• Auto – Fully automatic full time four-wheel
drive operation can be used on and off
road. Balances traction with seamless
steering feel to provide improved handling
and acceleration over two-wheel drive ve-
hicles. If equipped with air suspension,
the level will change to Normal Ride
Height (NRH).
• Sand – Off road calibration for use on low
traction surfaces such as sand or wet
grass. Driveline is maximized for traction.
Some binding may be felt on less forgiving
surfaces. The electronic brake controls are
set to limit traction control management of throttle and wheel spin. If equipped
with air suspension, the default ride
height for Sand is Normal Ride Height
(NRH).
• Mud – Off road calibration for use on low
traction surfaces such as mud. Driveline is
maximized for traction. Some binding may
be felt on less forgiving surfaces. The
electronic brake controls are set to limit
traction control management of throttle
and wheel spin. If equipped with air sus-
pension, the level will change to Off Road
1.
• Rock – Off road calibration only available
in 4WD Low range. The vehicle is raised (if
equipped with Air Suspension) for im-
proved ground clearance. Traction based
tuning with improved steer-ability for use
on high traction off-road surfaces. Use for
low speed obstacles such as large rocks,
deep ruts, etc. If equipped with air sus-
pension, the vehicle level will change to
Off-Road 2. If the Selec-Terrain switch is
in ROCK mode, and the transfer case is
switched from 4WD Low to 4WD High, the
Selec-Terrain system will return to AUTO.

Metric Speed (km/h)
• Pushing the SET-button once will result
in a 1 km/h decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 km/h.
• If the button is continually pushed, the set speed will continue to decrease in
10 km/h decrements until the button is
released. The decrease in set speed is
reflected in the instrument cluster display.
To Resume
If there is a set speed in memory push the
RES (resume) button and then remove your
foot from the accelerator pedal. The instru-
ment cluster display will show the last set
speed.
NOTE:
• If your vehicle stays at standstill for longerthan two seconds, then the system will
cancel and the brake force will be ramped-
out. The driver will have to apply the
brakes to keep the vehicle at a standstill.
• ACC cannot be resumed if there is a sta- tionary vehicle in-front of your vehicle in
close proximity.
WARNING!
The Resume function should only be used
if traffic and road conditions permit. Re-
suming a set speed that is too high or too
low for prevailing traffic and road condi-
tions could cause the vehicle to accelerate
or decelerate too sharply for safe opera-
tion. Failure to follow these warnings can
result in a collision and death or serious
personal injury.
Deactivation
Push and release the Adaptive Cruise Control
(ACC) ON/OFF button a second time to turn
the system off.
“Adaptive Cruise Control (ACC) Off” will ap-
pear in the instrument cluster display to in-
dicate the ACC is off.
Setting The Following Distance
The specified following distance for ACC can
be set by varying the distance setting be-
tween four bars (longest), three bars (long),
two bars (medium) and one bar (short). Using
this distance setting and the vehicle speed, ACC calculates and sets the distance to the
vehicle ahead. This distance setting appears
in the instrument cluster display.
• To increase the distance setting, push the
Distance Setting—Increase button and re-
lease. Each time the button is pushed, the
distance setting increases by one bar (lon-
ger).
• To decrease the distance setting, push the Distance Setting—Decrease button and
release. Each time the button is pushed,
the distance setting decreases by one bar
(shorter).
Changing Modes
If desired, the Adaptive Cruise Control mode
can be turned off and the system can be
operated as a normal (Fixed Speed) Speed
Control mode. When in the normal (Fixed
Speed) Speed Control mode the distance
setting feature will be disabled and the sys-
tem will maintain the speed you set.
• To change between the different cruisecontrol modes, push the ADAPTIVE
CRUISE CONTROL (ACC) ON/OFF button
which turns the ACC and the normal (Fixed
Speed) Speed Control OFF.

LANESENSE
LaneSense Operation
The LaneSense system is operational at
speeds above 37 mph (60 km/h) and below
112 mph (180 km/h). The LaneSense system
uses a forward looking camera to detect lane
markings and measure vehicle position
within the lane boundaries.
When both lane markings are detected and
the driver unintentionally drifts out of the
lane (no turn signal applied), the LaneSense
system provides a haptic warning in the form
of torque applied to the steering wheel to
prompt the driver to remain within the lane
boundaries. If the driver continues to unin-
tentionally drift out of the lane, the La-neSense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane
boundaries.
The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across
the lane marking (no turn signal applied), the
LaneSense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane.
When only a single lane marking is detected,
a haptic (torque) warning will not be pro-
vided.
NOTE:
When operating conditions have been met,
the LaneSense system will monitor if the
driver’s hands are on the steering wheel and
provides an audible warning to the driver
when the driver’s hands are not detected on
the steering wheel. The system will cancel if
the driver does not return their hands to the
wheel.

Turning LaneSense ON Or OFF
The default status of LaneSense is “OFF”.
The LaneSense button is located on the
switch panel below the Uconnect display.
To turn the LaneSense system ON, push the
LaneSense button to turn the system ON
(LED turns off). A “Lane Sense On” message
is shown in the instrument cluster display.
To turn the LaneSense system OFF, push the
LaneSense button once to turn the system
OFF (LED turns on).
NOTE:
The LaneSense system will retain the last
system state ON or OFF from the last ignition
cycle when the ignition is changed to the
ON/RUN position.
LaneSense Warning Message
The LaneSense system will indicate the cur-
rent lane drift condition through the instru-
ment cluster display.7.0 Instrument Cluster Display
When the LaneSense system is ON; the lane
lines are gray when both of the lane bound-
aries have not been detected and the La-
neSense indicator is solid white.
Left Lane Departure — Only Left Lane Detected
• When the LaneSense system is ON, the
LaneSense indicator is solid white when
only the left lane marking has been de-
tected and the system is ready to provide
visual warnings in the instrument cluster
display if an unintentional lane departure
occurs.
• When the LaneSense system senses the lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off), the left thin line
remains solid yellow and the LaneSense
indicator changes from solid white to
flashing yellow.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure
when only the right lane marking has been
detected. Left Lane Departure — Both Lanes Detected
• When the LaneSense system is ON, the
lane lines turn from gray to white to indi-
cate that both of the lane markings have
been detected. The LaneSense indicator
is solid green when both lane markings
have been detected and the system is ON
to provide visual warnings in the instru-
ment cluster display and a torque warning
in the steering wheel if an unintentional
lane departure occurs.
• When the LaneSense system senses a lane drift situation, the left thick lane line and
left thin line turn solid yellow. The La-
neSense indicator changes from solid
green to solid yellow. At this time torque is
applied to the steering wheel in the oppo-
site direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
• When the LaneSense system senses the lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off) and the left thin
line remains solid yellow. The LaneSense
indicator changes from solid yellow to

SCHEDULED SERVICING
NON-SRT
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe op-erating conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers. Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look
for unusual wear or damage.
• Check the fluid levels of the coolant reser- voir, brake master cylinder and fill as
needed.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the
following pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.SERVICING AND MAINTENANCE
