power steering JEEP GRAND CHEROKEE 2017 WK2 / 4.G Owner's Manual

Supplemental Restraint System (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask your autho-
rized dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors• Seat Belt Pretensioners
• Seat Belt Buckle Switch
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START or
ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup. The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on inter- mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air
bag system immediately.

WARNING!
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
• ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall
or slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
with the accelerator, brake, or clutch
pedals.
• If the vehicle carpet has been removed
and re-installed, always properly attach
WARNING!
carpet to the floor and check the floor
mat fasteners are secure to the vehicle
carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, engine coolant, oil, or other
fluid leaks. Also, if gasoline fumes are de-
tected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are sus-
pected. The cause should be located and
corrected immediately.

Center High-Mounted Stop Lamp (CHMSL)
The center high mounted stop lamp is an
LED. Service at an authorized dealer.
Rear License Lamp
The rear license lamps are LEDs. See your
authorized dealer for service.
FUSES
WARNING!
• When replacing a blown fuse, always usean appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Failure to use proper fuses may
result in serious personal injury, fire
and/or property damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-
tem), power unit systems (engine sys-
tem, gearbox system) or steering system
blows, contact an authorized dealer.
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work you must check
the electrical circuit inside the fuse for a
break/melt.
Also please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Underhood Fuses
The Power Distribution Center is located in
the engine compartment near the battery.
This center contains cartridge fuses, micro
fuses, relays, and circuit breakers. A descrip-
tion 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.

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 sys-
tem failure.
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
CAUTION!
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
