2017 JEEP COMPASS tires

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
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 commercial
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. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
weight limitations are met. Store the heavier items down
low and be sure that the weight is distributed equally. Stow
all loose items securely before driving.6
STARTING AND OPERATING 223

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 damage
to brakes, axle, engine, transmission, steering, sus-
pension, 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.
• 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 utilized.
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.
• Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
230 STARTING AND OPERATING

•When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement proce-
dures. Replacing tires with a higher load carrying capac-
ity will not increase the vehicle’s GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes
•Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
•Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have a collision.
• Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 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.

STARTING AND OPERATING 231

When To Use Low (L Off-Road) With The 4WD Lock
Lever Engaged — If Equipped
When driving off-road, shift into low (L Off-Road [if
equipped] ) and activate the 4WD LOCK. This will provide
additional traction and activates the numerous off-road
features to improve handling and control on slippery or
difficult terrain. Due to the sustained lower gearing, low (L
Off-Road [if equipped] ) with 4WD LOCK engaged will
allow the engine to operate in a higher power range. This
will allow you to cross over obstacles and descend hills,
with improved control and less effort.
NOTE:For maximum off-road performance, premium
fuel is recommended. While the vehicle will operate on
regular fuel when in L Off-Road mode (if equipped), the
engine has been calibrated for maximum performance
using premium fuel.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore, you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum. Snow
In heavy snow or for additional control and traction at
slower speeds, activate the 4WD LOCK and shift the
transaxle to low (L Off-Road [if equipped] ) if necessary. Do
not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels and
traction will be lost. If you start to slow to a stop, try
turning your steering wheel no more than a 1/4 turn
quickly back and forth, while still applying throttle. This
will allow the tires to get a fresh
biteand help maintain
your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPM’s or vehicle speeds because engine brak-
ing may cause skidding and loss of control.
Mud
Deep mud creates a great deal of suction around the tires and
is very difficult to get through. You should use low
(L Off-Road [if equipped] ) with the 4WD LOCK engaged
and maintain your momentum. If you start to slow to a stop,
try turning your steering wheel no more than a 1/4 turn
quickly back and forth for additional traction. Mud holes
6
STARTING AND OPERATING 237

pose an increased threat of vehicle damage and getting stuck.
They are normally full of debris from previous vehicles
getting stuck. As a good practice before entering any mud
hole, get out and determine how deep it is, if there are any
hidden obstacles and if the vehicle can be safely recovered if
stuck.
Sand
Soft sand is very difficult to travel through with full tire
pressure. When crossing soft sandy spots in a trail maintain
your vehicle’s momentum and do not stop. The key to
driving in soft sand is using the appropriate tire pressure,
accelerating slowly, avoiding abrupt maneuvers and main-
taining the vehicle’s momentum. If you are going to be
driving on large soft sandy areas or dunes, reduce your tire
pressure to a minimum of 15 psi (103 kPa) to allow for a
greater tire surface area. You should use low (L Off-Road [if
equipped] ) with the 4WD LOCK engaged and ESC turned
off. Reduced tire pressure will drastically improve your
traction and handling, while driving on the soft sand, but
you must return the tires to normal air pressure before
driving on pavement or other hard surfaces. Be sure you
have a way to reinflate the tires prior to reducing the
pressure.
CAUTION!
Reduced tire pressures may cause tire unseating and
total loss of air pressure. To reduce the risk of tire
unseating, while at a reduced tire pressure, reduce your
speed and avoid sharp turns or abrupt maneuvers.
Hill Climbing
Hill climbing requires good judgment and a good under-
standing of your abilities and your vehicle’s limitations.
Hills can cause serious problems. Some are just too steep to
climb and should not be attempted. You should always feel
confident with the vehicle and your abilities. You should
always climb hills straight up and down. Never attempt to
climb a hill on an angle.
Before Climbing A Steep Hill
As you approach a hill consider its grade or steepness.
Determine if it is too steep. Look to see what the traction is
on the hill side trail. Is the trail straight up and down?
What is on top and the other side? Are there ruts, rocks,
branches or other obstacles on the path? Can you safely
recover the vehicle if something goes wrong? If everything
looks good and you feel confident, then you should use
238 STARTING AND OPERATING

low (L Off-Road [if equipped]) with the 4WD LOCK
engaged and proceed with caution maintaining your mo-
mentum as you climb the hill.
Driving Up Hill
Once you have determined your ability to proceed and
have shifted into the appropriate gear, line your vehicle up
for the straightest possible run. Accelerate with an easy
constant throttle and apply more power as you start up the
hill. Do not race forward into a steep grade; the abrupt
change of grade could cause you to lose control. If the front
end begins to bounce, ease off the throttle slightly to bring
all four tires back on the ground. As you approach the crest
of the hill, ease off the throttle and slowly proceed over the
top. If the wheels start to slip as you approach the crest of
a hill, ease off the accelerator and maintain headway by
turning the steering wheel no more than a 1/4 turn quickly
back and forth. This will provide a freshbiteinto the
surface and will usually provide enough traction to com-
plete the climb. If you do not make it to the top, place the
vehicle in REVERSE and back straight down the grade
using engine resistance along with the vehicle brakes.WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases
the risk of a rollover, which may result in severe injury.
Driving Down Hill
Before driving down a steep hill you need to determine if
it is too steep for a safe descent. What is the surface
traction? Is the grade too steep to maintain a slow con-
trolled descent? Are there obstacles? Is it a straight descent?
Is there plenty of distance at the base of the hill to regain
control if the vehicle descends to fast? If you feel confident
in your ability to proceed then make sure you are in low (L
Off-Road [if equipped] ) with the 4WD LOCK engaged and
proceed with caution. Allow engine and hill descent brak-
ing to control the descent and apply your brakes if neces-
sary, but do not allow the tires to lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.

STARTING AND OPERATING 239

Driving Across An Incline
If at all possible avoid driving across an incline. If it is
necessary, know your vehicle’s abilities. Driving across an
incline places more weight on the down-hill wheels, which
increases the possibilities of a down-hill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible transverse the incline at an angle
heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll-
over, which may result in severe injury.
If You Stall Or Begin To Lose Headway
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift to REVERSE.
Back slowly down the hill allowing engine and hill descent
braking to control the descent and apply your brakes if
necessary, but do not allow the tires to lock.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle, which may result in severe injury.
Always back carefully straight down a hill in RE-
VERSE gear. Never back down a hill in NEUTRAL
using only the vehicle brakes. Never drive diagonally
across a hill, always drive straight up or down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible, and only be
attempted when necessary in a safe responsible manner.
You should only drive through areas which are designated
and approved. You should tread lightly and avoid damage
to the environment. You should know your vehicles abili-
ties and be able to recover it if something goes wrong. You
should never stop or shut a vehicle off when crossing deep
water unless you ingested water into the engine air intake.
If the engine stalls, do not attempt to restart it. Determine
if it has ingested water first. The key to any crossing is low
and slow. You want to use low (L Off-Road [if equipped] )
with the 4WD LOCK engaged and proceed very slowly
240 STARTING AND OPERATING

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.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
