2023 JEEP GRAND CHEROKEE headlamp

STARTING AND OPERATING123
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)

Your vehicle is equipped with an EPB that offers
simple operation, and some additional features that
make the parking brake more convenient and useful.

The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure the parking brake is
applied. Also, be certain to leave the transmission
in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the Customer Programmable
Features section of the Uconnect settings. The parking brake switch is located on the
instrument panel to the left of the steering wheel
(below the headlamp switch).

Electric Park Brake Switch

To apply the parking brake manually, pull up on the
switch momentarily. You may hear a sound from
the back of the vehicle while the parking brake
engages. Once the parking brake is fully engaged,
the BRAKE telltale light in the instrument cluster
and an indicator on the switch will illuminate. If
your foot is on the brake pedal while you apply the
parking brake, you may notice a small amount of
brake pedal movement. The parking brake can be
applied even when the ignition switch is OFF but
the BRAKE telltale light will not illuminate,
however, it can only be released when the ignition
is in the ON/RUN position.
NOTE:The EPB Warning Light will illuminate if the EPB
switch is held for longer than 20 seconds in either
the released or applied position. The light will extin -
guish upon releasing the switch.
If the Auto Park Brake feature is enabled, the
parking brake will automatically engage whenever
the transmission is placed into PARK. If your foot is
on the brake pedal, you may notice a small amount
of brake pedal movement while the parking brake
is engaging.
The parking brake will release automatically when
the ignition is ON, the transmission is in DRIVE or
REVERSE, the driver seat belt is buckled, and an
attempt is made to drive away.
To release the parking brake manually, the ignition
switch must be in the ON/RUN position. Put your
foot on the brake pedal, then push the EPB switch
down momentarily. You may hear a sound from the
back of the vehicle while the parking brake
disengages. You may also notice a small amount of
movement in the brake pedal. Once the parking
brake is fully disengaged, the BRAKE telltale light
in the instrument cluster and the LED indicator on
the switch will extinguish.CAUTION!
Never use non-detergent oil or straight mineral
oil in the engine or damage may result.

SERVICING AND MAINTENANCE353
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.

Blade Fuses

Underhood Fuses
The Power Distribution Center (PDC) is located on
the passenger side of the engine compartment,
behind the headlamp. This center contains
cartridge fuses, micro fuses, relays, and circuit
breakers. A description of each fuse and
component may be stamped on the inside cover,
otherwise the cavity number of each fuse is
stamped on the inside cover that corresponds to
the following chart.
1 — Fuse Element
2 — Blade Fuse with a good/functional fuse
element
3 — Blade fuse with a bad/not functional fuse
element (blown fuse)
CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit the
fuse box, and the windshield wiper motor with
water.
CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the power
distribution center and possibly result in an
electrical system failure.
