2021 JEEP GRAND CHEROKEE open hood

WARNING!
Do not attempt jump starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump Start
The battery in your vehicle is located under
the passenger's front seat. There are remote
terminals located under the hood to assist in
jump starting.WARNING!
• 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.
WARNING!
• 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.
NOTE:
Be sure that the disconnected cable ends do
not touch each other, or either vehicle, until
properly connected for jump starting.
1. Apply the parking brake, shift the auto-
matic transmission into PARK and turn
the ignition OFF.
2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. Remove the protective cover over the re-
mote positive(+)battery post. Pull up-
ward on the cover to remove it.

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.
IN CASE OF EMERGENCY
228

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 open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the sys-
tem should be drained, flushed, and refilled
with fresh OAT coolant (conforming to
MS.90032) by an authorized dealer. Check
the front of the A/C condenser for any accu-
mulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the en-
tire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
