auxiliary battery JEEP GRAND CHEROKEE 2020 Owner handbook (in English)

3. Disconnect the positive(+)end of the
jumper cable from the positive(+)post of
the booster battery.
4. Disconnect the opposite end of the posi-
tive(+)jumper cable from the remote
positive(+)post of the discharged
vehicle.
5. Reinstall the protective cover over the
remote positive(+)post of the discharged
vehicle.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system tested at an authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is
located in the spare tire storage area. If your
vehicle is out of fuel and an auxiliary fuel can
is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.
For more information on the Cap-Less Fuel
System refer to “Refueling The Vehicle” in
“Starting And Operating”.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes.NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
• You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.

Audio Jack (AUX)
• The AUX allows a device to be plugged into
the radio and utilize the vehicle’s sound
system, using a 3.5 mm audio cable, to
amplify the source and play through the
vehicle speakers.
• Pressing the “AUX” button on the touch-
screen will change the mode to auxiliary
device if the audio jack is connected, allow-
ing the music from your device to be heard
through the vehicle's speakers. To activate
the AUX, plug in the audio jack.
• The functions of the device are controlled
using the device buttons. The volume may
be controlled using the radio or device.
USB Port
• Connect your compatible device into the
USB Port using a USB cable. USB Memory
sticks with audio files can also be used.
Audio from the device can be played on the
vehicle’s sound system while providing
metadata (artist, track title, album, etc.)
information on the radio display.• When connected, the compatible USB de-
vice can be controlled using the radio or
Steering Wheel Audio Controls to play, skip
to the next or previous track, browse, and
list the contents.
• The battery charges when plugged into the
USB port (if supported by the specific de-
vice).
• To route the USB cable out of the center
console, use the access cut out.
NOTE:
When connecting your device for the first
time, the system may take several minutes to
read your music, depending on the number of
files. For example, the system will take ap-
proximately five minutes for every
1,000 songs loaded on the device. Also dur-
ing the reading process, the Shuffle and
Browse functions will be disabled. This pro-
cess is needed to ensure the full use of your
features and only happens the first time it is
connected. After the first time, the reading
process of your device will take considerably
less time unless changes are made or new
songs are added to the playlist.
Bluetooth Streaming Audio
If using a Bluetooth equipped device you may
also be able to stream music to your vehicle's
sound system. Your connected device must
be Bluetooth compatible and paired with
your system (see Uconnect Phone for pairing
instructions). You can access the music from
your connected Bluetooth device by pressing
the “Bluetooth” button on the touchscreen
while in Media mode.
