Jump Starting Procedure - Jeep GRAND CHEROKEE 2023 Owner's Manual

290 IN CASE OF EMERGENCY
See the following steps to prepare for jump starting:
1. Apply the parking brake, shift the automatic
transmission into PARK (P) and turn the ignition OFF.
2. Turn off the heater, radio, and all electrical
accessories.
3. If using another vehicle to jump start the battery, park
the vehicle within the jumper cables' reach, apply the
parking brake and make sure the ignition is OFF.
WARNING!
 Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result. Do not allow the disconnected
cable ends to touch each other, or either vehicle,
until properly connected for jump starting.
 Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
 Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
 Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
