2012 JEEP PATRIOT suspension

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.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
318 STARTING AND OPERATING

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
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.
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.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier suspension compo-
nents do not necessarily increase the vehicle’s GVWR.
374 STARTING AND OPERATING

WARNING! (Continued)
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
•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.
(Continued)
WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. Always block orchock
the trailer wheels.
•GCWR must not be exceeded.
•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 (This requirement may limit the ability to
always achieve the 10% to 15% range of tongue
weight as a percentage of total trailer weight).
382 STARTING AND OPERATING

•FWD vehicles can be towed with the front wheels
elevated.
•FWD or 4WD vehicles can be towed on a flatbed truck
(all wheelsOFFthe ground).
CAUTION!
DO NOT flat tow disabled vehicle if condition is
related to the clutch, transmission or driveline.
Additional damage to the drivetrain could result.
All Transmissions
If you must use the accessories (wipers, defroster, etc.)
while being towed (wipers, defrosters, etc.), the key must
be in the ON/RUN position, not the ACC position. Make
certain the transmission remains in NEUTRAL.
If the vehicle’s battery is discharged, see “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.
CAUTION!
Failure to follow these cautions could result in dam-
age to your vehicle:
•Do not attempt to use sling-type equipment when
towing. When securing the vehicle to a flatbed
truck, do not attach to front or rear suspension
components.
•If the vehicle being towed requires steering, the
ignition switch must be in the ON/RUN or ACC
position, not in the LOCK/OFF position.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
