Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will
check many safety and comfort conditions to
see if they are fulfilled. Detailed information
about the operation of the Stop/Start system
may be viewed in the instrument cluster
Stop/Start Screen. In the following situations
the engine will not stop:
Driver’s seat belt is not buckled.
Driver’s door is not closed.
Battery temperature is too warm or cold.
The vehicle is on a steep grade.
Cabin heating or cooling is in process and
an acceptable cabin temperature has not
been achieved.
HVAC is set to full defrost mode at a high
blower speed.
Engine has not reached normal operating
temperature.
Battery charge is low.
The transmission is not in DRIVE (auto-
matic transmission) or NEUTRAL (manual
transmission).
Hood is open.
Vehicle is in 4WD LOW transfer case
mode.
Exhaust system regeneration in process.
Other Factors Which Can Inhibit Autostop
Include:
Fuel level.
Accelerator pedal input (automatic trans-
mission only).
Engine temperature too high.
It may be possible for the vehicle to be driven
several times without the Stop/Start system
going into a STOP/START READY state
under more extreme conditions of the items
listed above.
To Start The Engine While In Autostop
Mode
Automatic Transmission:

While in DRIVE, the engine will start when the
brake pedal is released or the throttle pedal is
depressed. The transmission will automatically
re-engage upon engine restart. During this tran -
sition, the brakes will hold the vehicle to avoid
undesired vehicle movement.
Manual Transmission:

When the gear selector is in NEUTRAL, the
engine will start when the clutch pedal is
pressed. The vehicle will go into STOP/START
SYSTEM NOT READY mode until the vehicle
speed is greater than 4 mph (7 km/h).

Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:

The transmission gear selector is moved
from DRIVE to REVERSE or NEUTRAL.
To maintain cabin temperature comfort.
HVAC is set to full defrost mode.
Battery voltage drops too low.
Low brake vacuum (e.g. after several brake
pedal applications).
Stop/Start OFF switch is pushed.
4WD system is put into 4WD LOW mode.
The emissions system requires it.
A Stop/Start system error occurs.
HVAC system temperature or fan speed is
manually adjusted.

Adblue® (UREA) — If Equipped
The vehicle is equipped with an UREA injec-
tion system and Selective Catalytic Reduc -
tion to meet emission standards. These two
systems ensure compliance with the diesel
emissions requirements; at the same time,
they ensure fuel-efficiency, handling, torque
and power. For messages and system warn -
ings, refer to the “Warning Lights And
Messages” in the “Getting To Know Your
Instrument Panel” section. AdBlue® (UREA)
is a very stable product with a long shelf life.
Stored at temperatures LOWER than 90 °F
(32 °C), it has a shelf life of at least one year.
For more information on the AdBlue® liquid
type, see the “Fluids and lubricants” in the
“Technical specifications” section. The
vehicle is equipped with an automatic
AdBlue® heating system when the engine
starts allowing the system to work correctly
at temperatures lower than 12 °F (-11 °C).
NOTE:
AdBlue® freezes at temperatures lower than
12 °F (-11 °C).
AdBlue® (UREA) Storage
AdBlue® (UREA) is considered a very stable
product with a long shelf life. If AdBlue®
(UREA) is kept in temperatures between 10°
and 90°F (-12° and 32°C), it will last a
minimum of one year.
AdBlue® (UREA) is subject to freezing at the
lowest temperatures. For example, AdBlue®
(UREA) may freeze at temperatures at or
below 12° F (-11° C). The system has been
designed to operate in this environment.
NOTE:
When working with AdBlue® (UREA), it is
important to know that:
Any containers or parts that come into
contact with AdBlue® (UREA) must be
AdBlue® (UREA) compatible (plastic or
stainless steel). Copper, brass, aluminum,
iron or non-stainless steel should be
avoided as they are subject to corrosion by
AdBlue® (UREA).
If AdBlue® (UREA) is spilled, it should be
wiped up completely.
Adding AdBlue® (UREA)
Preliminary Conditions
AdBlue® (UREA) freezes at temperatures
lower than 12° F (-11° C). If the car stands
for a long time at this temperature refilling
could be difficult. For this reason, it is
advised to park the vehicle in a garage and/
or heated environment and wait for the
UREA to return to liquid state before topping
up.
Proceed as follows:
Park the car on flat ground and stop the
engine by placing the ignition in the OFF
position.
Open the fuel door, undo and remove the
cap (blue) from the AdBlue® (UREA)
filler.

Fuel And AdBlue® (UREA) Filler Location
Refilling With Nozzles
You can fill up at any AdBlue® (UREA)
distributor.
Proceed as follows:
Insert the AdBlue® (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that
the AdBlue® (UREA) tank is full). Do not
proceed with the refilling, to prevent
spillage of AdBlue® (UREA).
Extract the nozzle. Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue® (UREA) tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument
panel display refer to “Warning lights And
Messages” in the “Getting To Know Your
Instrument Panel” for further information,
fill the AdBlue® (UREA) tank with no
more than 1.6 Gallons (6 liters).
If containers which can be screwed to the
filler are used, the reservoir is full when
the AdBlue® (UREA) level in the
container stops pouring out. Do not
proceed further.
Operations After Refilling
Proceed as follows:
Fit the cap back on the AdBlue® (UREA)
filler by turning it clockwise and screwing
it completely.
Place the ignition to RUN (it is not neces-
sary to start the engine).
Wait for the indication on the instrument
panel to switch off before moving the car.
The indication may stay on for a few
seconds to approximately half a minute. If
the engine is started and the car is moved,
the indication will remain on for longer.
This will not compromise engine opera-
tion.
If the AdBlue® (UREA) was topped up
when the tank was empty, wait for
2 minutes before starting the engine.

NOTE:
If AdBlue® (UREA) is spilled out of the
filler neck, clean up well the area and
proceed to filling up again. If the liquid
crystallizes, eliminate it with a sponge and
warm water.
DO NOT EXCEED THE MAXIMUM LEVEL:
this could cause damage to the reservoir.
AdBlue® (UREA) freezes at under 12° F
(-11° C). Although the system is designed
to operate below the freezing point of the
UREA, it is advisable not to fill the tank
beyond the maximum level because if the
UREA freezes the system can be
damaged. Follow the instructions in this
section.
If the AdBlue® (UREA) is spilled on
painted surfaces or aluminum, immedi-
ately clean the area with water and use
absorbent material to collect the fluid that
has been spilled on the ground.
Do not try to start the engine if AdBlue®
(UREA) was accidentally added to the
diesel fuel tank, this can result in serious
engine damage, contact an authorized
dealer.
Do not add additives or other fluids to
AdBlue® (UREA), doing so could damage
the system.
The use of non-conforming or degraded
AdBlue® (UREA) may lead to indications
appearing on the instrument panel display
refer to “Warning Lights And Messages” in
the “Getting To Know Your Instrument
Panel” for further information.
Never pour AdBlue® (UREA) into another
container: it could be contaminated.
If the AdBlue® (UREA) runs out, see refer
to “Warning Lights And Messages” in the
“Getting To Know Your Instrument Panel”
for further information to continue using
the car normally.
VEHICLE LOADING
Weights Label
As required by local regulations, your vehicle
has a weights label affixed to the driver's side
door or pillar. Weights Label (Example)
This label contains:
1. The manufacturer’s company name
2. The whole vehicle type-approval number
3. The Vehicle Identification Number (VIN)
4. Gross Vehicle Weight Rating (GVWR)
5. Gross Combined Weight Rating (GCWR)
6. Front Gross Axle Weight Rating (FGAWR)
7. Rear Gross Axle Weight Rating (RGAWR)
NOTE:
For specific markets the label could be
different, respect the one shown in the image
contains: the GVWR, GAWR front and rear.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 177

STARTING AND OPERATING
178
Gross Vehicle Weight Rating (GVWR)
The Gross Vehicle Weight Rating (GVWR) is
the total permissible weight of your vehicle
including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear axle
systems (GAWR). Total load must be limited
so GVWR and front and rear GAWR are not
exceeded.
Payload
The payload of a vehicle is defined as the
allowable load weight a truck can carry,
including the weight of the driver, all passen-
gers, options and cargo.
Gross Axle Weight Rating (GAWR)
The Gross Axle Weight Rating (GAWR) is the
maximum permissible load on the front and
rear axles. The load must be distributed in
the cargo area so that the GAWR of each axle
is not exceeded.
Each axle GAWR is determined by the
components in the system with the lowest
load carrying capacity (axle, springs, tires or
wheels). Heavier axles or suspension compo -nents sometimes specified by purchasers for
increased durability does not necessarily
increase the vehicle's GVWR.
Curb Weight
The curb weight of a vehicle is defined as the
total weight of the vehicle with all fluids,
including vehicle fuel, at full capacity condi
-
tions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb
weight values are determined by weighing
your vehicle on a commercial scale before
any occupants or cargo are added.
Loading
The actual total weight and the weight of the
front and rear of your vehicle at the ground
can best be determined by weighing it when
it is loaded and ready for operation.
The entire vehicle should first be weighed on
a commercial scale to ensure that the GVWR
has not been exceeded. The weight on the
front and rear of the vehicle should then be
determined separately to be sure that the
load is properly distributed over the front and
rear axle. Weighing the vehicle may show
that the GAWR of either the front or rear
axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified
weight limitations are met. Store the heavier
items down low and be sure that the weight
is distributed equally. Stow all loose items
securely before driving.
Improper weight distributions can have an
adverse effect on the way your vehicle steers
and handles and the way the brakes operate.
CAUTION!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your
vehicle handles. This could cause you to
lose control. Also overloading can shorten
the life of your vehicle.
