2016 JEEP GRAND CHEROKEE open hood

WARNING!
•Take care to avoid the radiator cooling fan when-
ever 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.
NOTE: Be sure that the disconnected ends of the cables
do not touch while still connected to the either vehicle.

WHAT TO DO IN EMERGENCIES 615

In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.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.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty, the
system 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

Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the brake system warning lamp indicates system
failure.
The brake master cylinder has a plastic reservoir. On the
outboard side of the reservoir, there is a “MAX” mark
and a “MIN” mark. The fluid level must be kept within
these two dots. Do not add fluid above the MAX mark,
because leakage may occur at the cap.
With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the

High Intensity Discharge Headlamps (HID) —
If Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of
this, you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE:
On vehicles equipped with High Intensity Dis-
charge (HID) headlamps, when the headlamps are turned on, there is a blue hue to the lamps. This diminishes and
becomes more white after approximately 10 seconds, as the
system charges.
Halogen Headlamps — If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn
counterclockwise to remove from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.

Front Turn Signal
1. Open the hood.
2. Turn the turn signal bulb one–quarter turn counter-clockwise to remove from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Fog Lamps
1. Reach through the cutout in the splash shield anddisconnect the wiring harness from the fog lamp
connector.
2. Firmly grasp the bulb by the two latches and squeeze them together to unlock the bulb from the back of the
front fog lamp housing.
3. Pull the bulb straight out from the keyed opening in the housing.
CAUTION!
•Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If
the bulb comes in contact with any oily surface,
clean the bulb with rubbing alcohol.
