Refueling In Emergency - Jeep GRAND CHEROKEE 2022 Owner's Manual

WARNING!
Do not connect the jumper cable to the negative (-)
post of the discharged battery. The resulting
electrical spark could cause the battery to explode
and could result in personal injury.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle
engine.
6. Once the engine is started, follow the discon-
necting procedure.
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the jumper
cable from the remote negative (-) post of the
discharged vehicle.
2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the
booster battery.
3. Disconnect the positive (+) end of the jumper
cable from the positive (+) post of the booster
battery.
4. Disconnect the opposite end of the positive (+)
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 have the battery and charging system
tested at an authorized dealer.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle'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
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
IN CASE OF EMERGENCY

REFUELING IN EMERGENCY

The vehicle is equipped with a refueling funnel
Ú page 306 for a Cap-Less Fuel System. If refueling is
necessary, while using an approved gas can, please
insert the refueling funnel into the filler neck opening.
Refueling Funnel
NOTE:
In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push
around the perimeter of the fuel door to break the
ice build up. Re-release the fuel door by pushing on
the rear outer edge near the center to unlatch.
Do not pry on the door.
