2012 JEEP GRAND CHEROKEE head light

Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the right side of the headlight switch) is rotated
to the its farthest upward position, or if equipped, when
the UNLOCK button is pressed on the Remote Keyless
Entry (RKE) transmitter. 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 without discharging the vehicle’s battery.
The brightness of the instrument panel lighting 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 odometer, trip odom-
eter, radio and overhead console by rotating the controlto its farthest position up until you hear a click. This
feature is termed the “Parade” mode and is useful when
headlights are required during the day.

Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster 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.
Lane Change Assist

the detent, and the turn signal (right or left) will flash
three times then automatically turn off.

You can signal another vehicle with your headlights by
partially pulling the multifunction lever toward the steer-
ing wheel. This will cause the high beam headlights to
turn on until the lever is released.

the low beams back on, or shut the high beams off.

On steep hills, a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor designed to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.

The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity. When this occurs, you should immediately
apply the brakes as needed to maintain a safe distance
from the vehicle ahead.
The ACC Systems provides Overtake Aid when passing
on the left hand side only. When driving with ACC
engaged and following a Target vehicle, the system willprovide an additional acceleration based on your current
speed. The acceleration is triggered by indicating a left
turn signal.
