warning lights JEEP GRAND CHEROKEE 2012 WK2 / 4.G Owners Manual

Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system provides
output appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.WARNING!
•No objects should be placed over or near the air
bag on the instrument panel, because any such
objects could cause harm if the vehicle is in a
collision severe enough to cause the air bag to
inflate.
•Do not put anything on or around the air bag
covers or attempt to open them manually. You may
damage the air bags and you could be injured
because the air bags may no longer be functional.
The protective covers for the air bag cushions are
designed to open only when the air bags are
inflating.
•Do not drill, cut or tamper with the knee bolster in
any way.
•Do not mount any accessories to the knee bolster
such as alarm lights, stereos, citizen band radios,
etc.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

•The system disengages. (Refer to the information on
ACC Activation).
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 will
provide an additional acceleration based on your current
speed. The acceleration is triggered by indicating a left
turn signal.

12. Park/Headlight ON Indicator — If EquippedThis indicator will illuminate when the park
lights or headlights are turned on.
13. Seat Belt Reminder Light When the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information. 14. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.

NOTE:
•Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
EVIC Amber Telltale Lights
This area will show reconfigurable amber caution tell-
tales. These telltales include:
•Forward Collision Warning (FCW) OFFThis light warns the driver of a potential colli-
sion with the vehicle in front and prompts the
driver to take action in order to avoid the
collision. For further information, refer to
“Adaptive Cruise Control (ACC)” in “Understanding
The Features Of Your Vehicle.”
•Air Suspension Up The air suspension up telltale will illuminate
when the air suspension is in use. For further
information, refer to “Starting And Operating”.

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing, you should allow for ad-
ditional space between your vehicle and the ve-
hicle in front of you. Failure to do so could result
in a collision.
Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package includes a seven–pin connector
at the rear of the vehicle and a four-pin harness located
under the rear bumper. The four-pin harness must be
unclipped before use. Use a factory-approved trailer
harness and connector.
534 STARTING AND OPERATING

Interior Care
Use MOPARTotal Clean or equivalent to clean fabric
upholstery and carpeting.
Interior Trim should be cleaned starting with a damp
cloth, a damp cloth with MOPAR Total Clean or equiva-
lent, then MOPAR Spot & Stain Remover or equivalent,
if absolutely necessary. Do not use harsh cleaners or
Armor All. Use MOPAR Total Clean or equivalent to
clean vinyl upholstery.
Leather Seat Care And Cleaning
MOPAR Total Clean or equivalent is specifically recom-
mended for leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPAR Total Clean or equivalent. Care should be taken to avoid soaking your leather upholstery with any
liquid. Please do not use polishes, oils, cleaning fluids,
solvents, detergents, or ammonia-based cleaners to clean
your leather upholstery. Application of a leather condi-
tioner is not required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas, they may cause respiratory harm.
Cleaning Headlights
Your vehicle has plastic headlights that are lighter and
less susceptible to stone breakage than glass headlights.
Plastic is not as scratch-resistant as glass and therefore
different lens cleaning procedures must be followed.

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.
