Jeep Grand Cherokee (2019 year). Instruction — part 25
If you stall or begin to lose forward motion
while
climbing a steep hill, allow your vehicle to come to a stop
and immediately apply the brakes. Restart the engine, and
shift into REVERSE. Back slowly down the hill, allowing
the compression braking of the engine to help regulate
your speed. If the brakes are required to control vehicle
speed, apply them lightly and avoid locking or skidding
the tires.
WARNING!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle. Always back carefully straight
down a hill in REVERSE gear. Never back down a hill
in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill. Always
drive straight up or down.
If the wheels start to slip as you approach the crest of a hill,
ease off the accelerator and maintain forward motion by
turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.
Traction Downhill
When descending mountains or hills, use Hill Descent or
Selec-Speed Control to avoid repeated heavy braking.
If not equipped with Hill Descent or Selec-Speed Control
use the following procedure:
Shift the transmission into a low gear, and the transfer case
into 4WD LOW range. Let the vehicle go slowly down the
hill with all four wheels turning against engine compres-
sion drag. This will permit you to control the vehicle speed
and direction.
When descending mountains or hills, repeated braking can
cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
388
STARTING AND OPERATING
• Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.

IN CASE OF EMERGENCY
WARNING!
• If anyone in the vehicle could be in danger (e.g., fire
or smoke is visible, dangerous road conditions or
location), do not wait for voice contact from an
Emergency Services Agent. All occupants should exit
the vehicle immediately and move to a safe location.
• Never place anything on or near the vehicle’s oper-
able network and GPS antennas. You could prevent

Bulb Replacement
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
NOTE:
Lens fogging can occur under certain atmospheric
conditions. This will usually clear as atmospheric condi-
tions change to allow the condensation to change back to
vapor. Turning the lamps on will usually accelerate the
clearing process.
1. Open the hood.
2. Access the back of the headlamp.
NOTE:
• The air filter housing must be removed.
• The windshield washer reservoir may need to be
rotated out of the way by removing the fastener.
• Coolant reservoir (if equipped) will need to be reposi-
tioned by removing the fasteners, and moving the unit
out of the way.
3. To access the low beam bulb you must remove the
rubber boot seal from backside of the lamp housing.
400
IN CASE OF EMERGENCY
NOTE:
Ensure the rubber boot is properly reinstalled to
prevent water and moisture from entering the lamp.
CAUTION!
• Do not contaminate the bulb glass by touching it
with your fingers or by allowing it to contact other
oily surfaces. Shortened bulb life will result.
• Always use the correct bulb size and type for replace-
ment. An incorrect bulb size or type may overheat
and cause damage to the lamp, the bulb socket, or the
lamp wiring.
4. Turn the low or high beam bulb one–quarter turn
counterclockwise to remove from housing.
5. Disconnect the electrical connector and replace the bulb.
