JEEP GRAND CHEROKEE 2017 WK2 / 4.G Service Manual

If the windshield or Automatic High Beam
Headlamp Control mirror is replaced, the
mirror must be re-aimed to ensure proper
performance. See your local authorized
dealer.
Parking Lights And Panel Lights
To turn on the parking lights and instrument
panel lights, rotate the headlight switch
clockwise. To turn off the parking lights,
rotate the headlight switch back to the O (Off)
position.
Headlight Delay
To aid in your exit, your vehicle is equipped
with a headlight delay that will leave the
headlights on for approximately up to 90 sec-
onds. This delay is initiated when the ignition
is turned OFF while the headlight switch is
on, and then the headlight switch is cycled
off. Headlight delay can be cancelled by
either turning the headlight switch on then
off, or by turning the ignition ON.NOTE:
This feature can be programmed through the
Uconnect system. Refer to “Uconnect Set-
tings” in “Multimedia” for further informa-
tion.
Fog Lights
The fog lights are turned on by rotating the
headlight switch to the parking light or head-
light position and pushing in the headlight
rotary control.
The fog lights will operate only when the
parking lights are on or when the vehicle
headlights are on low beam. An indicator
light located in the instrument cluster display
will illuminate when the fog lights are on. The
fog lights will turn off when the switch is
pushed a second time, when the headlight
switch is rotated to the off position, or the
high beam is selected.
Turn Signals
Move the multifunction lever up or down and
the arrows on each side of the instrument
cluster display flash to show proper operation
of the front and rear turn signal lights.
NOTE:
If either light remains on and does not flash,
or there is a very fast flash rate, check for a
defective outside light bulb. If an indicator
fails to light when the lever is moved, it would
suggest that the indicator bulb is defective.
Fog Light Operation
39

Lane Change Assist
Tap the lever up or down once, without mov-
ing beyond the detent, and the turn signal
(right or left) will flash three times then
automatically turn off.
INTERIOR LIGHTS
Courtesy Interior Lights
Courtesy and dome lights are turned on when
the front doors are opened or when the dim-
mer control (rotating wheel on the right side
of the headlight switch) is rotated to its
farthest upward position. If your vehicle is
equipped with Remote Keyless Entry and the
UNLOCK button is pushed on the key fob, the
courtesy and dome lights will turn on. When a
door is open and the interior lights are on,
rotating the dimmer control all the way down,
to the OFF detent, will cause all the interior
lights to go out. This is also known as the
“Party” mode because it allows the doors to
stay open for extended periods of time with-
out discharging the vehicle’s battery.The brightness of the instrument panel light-
ing can be regulated by rotating the dimmer
control up (brighter) or down (dimmer). When
the headlights are on you can supplement the
brightness of the instrument cluster display,
radio and overhead console by rotating the
control to its farthest position up until you
hear a click. This feature is termed the “Pa-
rade” mode and is useful when headlights
are required during the day.
WIPER/WASHER
The multifunction lever is located on the left
side of the steering column.
Front Wipers
The windshield wiper/washer controls are lo-
cated on the multifunction lever on the left
side of the steering column. The front wipers
are operated by rotating a switch, located on
the end of the lever. For information on the
rear wiper/washer, refer to “Rear Wiper” in
this section.
Wiper Operation
Rotate the end of the lever to one of the first
four detent positions for intermittent set-
tings, the fifth detent for low wiper operation
and the sixth detent for high wiper operation.

CAUTION!
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the PARK position. If the
windshield wiper switch is turned off, and
the blades cannot return to the PARK
position, damage to the wiper motor may
occur.
Rain Sensor
This feature senses moisture on the wind-
shield and automatically activates the wipers
for the driver. The feature is especially useful
for road splash or overspray from the wind-
shield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of
four settings to activate this feature.
Automatic Wiping
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay po-
sition one is the least sensitive, and wiper
delay position four is the most sensitive.
Setting three should be used for normal rain
conditions. Settings one and two can be used
if the driver desires less wiper sensitivity.Setting four can be used if the driver desires
more sensitivity. Place the wiper switch in the
OFF position when not using the system.
NOTE:
• The Rain Sensing feature will not operate
when the wiper switch is in the low or
high-speed position.
• The Rain Sensing feature may not function properly when ice, or dried salt water is
present on the windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing per-
formance.
• The Rain Sensing feature can be turned on and off using the Uconnect System, refer
to “Uconnect Settings” in “Multimedia”
in the Owners Manual at
www.jeep.com/en/owners/manuals/ for
further information.
The Rain Sensing system has protection fea-
tures for the wiper blades and arms, and will
not operate under the following conditions: •
Low Ambient Temperature — When the ig-
nition is first turned ON, the Rain Sensing
system will not operate until the wiper
switch is moved, vehicle speed is greater
than 0 mph (0 km/h), or the outside tem-
perature is greater than 32°F (0°C).
• Transmission In NEUTRAL Position — When
the ignition is ON, and the automatic
transmission is in the NEUTRAL position,
the Rain Sensing system will not operate
until the wiper switch is moved, vehicle
speed is greater than 3 mph (5 km/h), or
the gear selector is moved out of the NEU-
TRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with Remote Starting system, Rain
Sensing wipers are not operational when the
vehicle is in the remote start mode. Once the
operator is in the vehicle and has placed the
ignition switch in the RUN position, rain
sensing wiper operation can resume, if it has
been selected, and no other inhibit condi-
tions (mentioned previously) exist.

Rear Wiper
The rear wiper/washer controls are located on
the multifunction lever on the left side of the
steering column. The rear wiper/washer is
operated by rotating a switch, located at the
middle of the lever.
Wiper Operation
Rotate the center portion of the lever upward
to the first detent for intermittent operation
and to the second detent for continuous rear
wiper operation.
Rotating the center portion upward once
more will activate the washer pump which
will continue to operate as long as the switch
is held. Upon release of the switch, the wip-
ers will resume the continuous rear wiper
operation. When this rotary control is in the
OFF position, rotating it downward will acti-
vate the rear washer pump which will con-
tinue to operate as long as the switch is held.
Once the switch is released it will return to
the OFF position and the wipers will cycle
several times before returning to the parked
position.NOTE:
As a protective measure, the pump will stop if
the switch is held for more than 20 seconds.
Once the switch is released the pump will
resume normal operation.
If the rear wiper is operating when the igni-
tion is turned OFF, the wiper will automati-
cally return to the “park” position.HEADLIGHT WASHERS — IF
EQUIPPED
The multifunction lever operates the head-
light washers when the ignition switch is in
the ON position and the headlights are
turned on. The multifunction lever is located
on the left side of the steering column.
To use the headlight washers, push the mul-
tifunction lever inward (toward the steering
column) and release it. The headlight wash-
ers will spray a timed high-pressure spray of
washer fluid onto each headlight lens. In
addition, the windshield washers will spray
the windshield and the windshield wipers will
cycle.
NOTE:
After turning the ignition switch and head-
lights ON, the headlight washers will operate
on the first spray of the windshield washer
and then every eleventh spray after that.
