2017 JEEP COMPASS check engine

CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steer-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do not
overfill. Use only manufacturer’s recommended power
steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids And Lubricants” in “Servicing
And Maintenance” for further information.
ELECTRONIC SPEED CONTROL — IF EQUIPPED
When engaged, the Electronic Speed Control takes over
accelerator operations at speeds greater than 25 mph
(40 km/h). The Electronic Speed Control buttons are located on the
right side of the steering wheel.
NOTE:
In order to ensure proper operation, the Electronic
Speed Control System has been designed to shut down if
multiple Speed Control functions are operated at the same
time. If this occurs, the Electronic Speed Control System
can be reactivated by pushing the Electronic Speed Control
ON/OFF button and resetting the desired vehicle set
speed.

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

with a constant slow speed (3-5 mph [5–8 km/h] maxi-
mum) and light throttle. Keep the vehicle moving; do not
try to accelerate through the crossing. After crossing any
water higher than the bottom of the axle differentials, you
should inspect all of the vehicle fluids for signs of water
ingestion.
CAUTION!
Water ingestion into the transaxle, transfer case, engine
or vehicle interior can occur if you drive too fast or
through too deep of water. Water can cause permanent
damage to engine, driveline or other vehicle compo-
nents and your brakes will be less effective once wet
and/or muddy.
Before You Cross Any Type Of Water
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick.
You need to be sure of its depth, approach angle, current
and bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure you will not
be intruding on any wildlife, and you can recover the
vehicle if necessary. The key to a safe crossing is the water
depth, current and bottom conditions. On soft bottoms, the vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to
entering. This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
CAUTION!
Muddy waters can reduce the cooling system effective-
ness by depositing debris onto the radiator.
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

5. Uncoil the Power Plug (8) and insert the plug into thevehicle’s 12 Volt power outlet.
NOTE: Do not remove foreign objects (e.g., screws or nails)
from the tire.
(C) Injecting Tire Service Kit Sealant Into The
Deflated Tire:
• Always start the engine before turning on the Tire
Service Kit.
NOTE: Manual transmission vehicles must have the park-
ing brake engaged and the gear selector in NEUTRAL.
• After pushing the Power Button (4), the sealant (white
fluid) will flow from the Sealant Bottle (1) through the
Sealant Hose (6) and into the tire.
NOTE: Sealant may leak out through the puncture in the
tire.
If the sealant (white fluid) does not flow within0–10
seconds through the Sealant Hose (6):
1. Push the Power Button (4) to turn off the Tire Service Kit. Disconnect the Sealant Hose (6) from the valve stem.
Make sure the valve stem is free of debris. Reconnect the
Sealant Hose (6) to the valve stem. Check that the Mode Select Knob (5) is in the Sealant Mode position and not
Air Mode. Push the Power Button (4) to turn on the Tire
Service Kit.
2. Connect the Power Plug (8) to a different 12 Volt power outlet in your vehicle or another vehicle, if available.
Make sure the engine is running before turning on the
Tire Service Kit.
3. The Sealant Bottle (1) may be empty due to previous use. Call for assistance.
NOTE: If the Mode Select Knob (5) is on Air Mode and the
pump is operating, air will dispense from the Air Pump
Hose (7) only, not the Sealant Hose (6).
If the sealant (white fluid) does flow through the Sealant
Hose (6):
1. Continue to operate the pump until sealant is no longer flowing through hose (typically takes 30 - 70 seconds).
As the sealant flows through the Sealant Hose (6), the
Pressure Gauge (3) can read as high as 70 psi (4.8 Bar).
The Pressure Gauge (3) will decrease quickly from
approximately 70 psi (4.8 Bar) to the actual tire pressure
when the Sealant Bottle (1) is empty.

SERVICING AND MAINTENANCE 281

Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a fully
warmed engine is shut off. Do not check oil level before
starting the engine after it has sat overnight. Checking
engine oil level when the engine is cold will give you an
incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone which depicts the MIN at the
low end of the range and MAX at the high end of the range.
Adding 1 quart (1 liter) of oil when the reading is at the low
end of the indicated range will result in the oil level at the
full end of the indicator range.
CAUTION!
Do not overfill the engine. Overfilling the engine will
cause oil aeration, which can lead to loss of oil pressure
and an increase in oil temperature. This could damage
your engine. Also, be sure the oil fill cap is replaced
and tightened after adding oil.
Cooling System
WARNING!
•When working near the radiator cooling fan, discon-
nect the fan motor lead or turn the ignition switch to
the OFF position. The fan is temperature controlled
and can start at any time the ignition switch is in the
ON position.
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator is hot.
