2014 JEEP CHEROKEE suspension

NOTE:Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum Set Speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-
plays “ACC Ready.”
When the system is OFF, the EVIC displays “Adaptive
Cruise Control (ACC) Off.” NOTE:
You cannot enable ACC under the following
conditions:
• When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in PARK, RE-
VERSE or NEUTRAL.
• When the Vehicle speed is outside of the speed range.
• When the brakes are overheated.
• When the driver door is open.
• When the driver seat belt is unbuckled.3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 193

Traction Downhill
Shift the transmission into a low gear and the 4WD
System to 4WD LOW range or Select Hill Descent
Control if equipped (refer toElectronic Brake Control
System in this section for further information). Let the
vehicle go slowly down the hill with all four wheels
turning against engine compression drag. This will per-
mit you to control the vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can get any problems taken care of right away and have
your vehicle ready when you need it.
•
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.

CAUTION!
•Use on Front Tires Only
• Damage to Front Wheel Drive (FWD) Models may
result if tire chains or traction devices are used with
original equipment size tires.
• Damage to Four Wheel Drive (4WD) Models with-
out a Two-Speed Power Takeoff Unit may result if
tire chains or traction devices are used with origi-
nal equipment size tires.
• Damage to Four Wheel Drive (4WD) Trailhawk
Models may result if tire chains or traction devices
are used with original equipment size tires.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance be-
tween tires and other suspension components, it is
important that only traction devices in good condi-
tion are used. Broken devices can cause serious
damage. Stop the vehicle immediately if noise
occurs that could indicate device breakage. Remove
the damaged parts of the device before further use.
• Install device as tightly as possible and then re-
tighten after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for a prolonged period on dry pave-
ment.

STARTING AND OPERATING 505

Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over the front and rear axle. Weigh-
ing the vehicle may show that the GAWR of either the5

WARNING!(Continued)
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission in
PARK. Always, block or chockthe trailer wheels.
• GCWR must not be exceeded.

WARNING! (Continued)
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.
CAUTION!
• Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.

WARNING!
Recovery straps should only be used in emergencies to
rescue stranded vehicles. Only use Recovery straps on
vehicles that fit within the recommended GVW of
your recovery strap. Only attach recovery straps to OE
recommended anchor points or emergency towing
anchor points. Never attach to tow ball or vehicle tie
down point, these are not designed for this purpose.
Never attach to vehicle steering, drive train, or any
other suspension components. NEVER pull a strap
over sharp edges or abrasive surfaces that can damage
the recovery strap. NEVER use a damaged strap, it has
reduced strength. DO NOT attempt to repair straps.
ONLY persons involved in the recovery should be in
either vehicle. No passengers. Anyone inside the ve-
hicles can be struck by strap recoil, causing serious
injury. MOVE bystanders at least 40 feet from the
recovery area when using the recovery strap.
Using Recovery Strap
1. Review all warnings and instructions first.
2. Position the recovery vehicle.
3. Connect the recovery strap.
4. Add a recovery damper or blanket.
5. Clear the danger zone.
6. Safely and slowly start pulling.
7. Disconnect the recovery strap after both vehicle aresecure and parked.
584 WHAT TO DO IN EMERGENCIES

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equip-
ment manufacturer ’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
main structural members of the vehicle, not to bumpers
or associated brackets. State and local laws regarding
vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Shift Lever Override” in this section
for instructions on shifting the transmission out of PARK
so that the vehicle can be moved.CAUTION!
•Do not use sling type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
Front-Wheel Drive (FWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFFthe ground using a flatbed.
If flatbed equipment is not available, this vehicle must
towed with the front wheels OFF the ground (using a
towing dolly, or wheel lift equipment with the front
wheels raised).6
