check engine light JEEP PATRIOT 2017 1.G User Guide

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.
238 STARTING AND OPERATING

Once A Month Or Before A Long Trip:
•Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and fill as needed
• Check function of all interior and exterior lights
Maintenance Plan
Required Maintenance Intervals.
Refer to the “Maintenance Plan” on the following pages for
the required maintenance intervals.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular
wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required.
• Inspect brake pads, shoes, rotors, drums, hoses and
park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or
off-road conditions.
278 SERVICING AND MAINTENANCE

•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” for the proper maintenance
intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be checked when
the pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
NOTE: If your vehicle is equipped with a manual trans-
mission, the brake fluid reservoir supplies fluid to both the
brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. The manual
transmission clutch release system should not require fluid
replacement during the life of the vehicle. If the brake fluid
reservoir is low and the brake system does not indicate any
leaks or other problems, it may be a result of a leak in the
hydraulic clutch release system. See your local authorized
dealer for service.

SERVICING AND MAINTENANCE 297

BRAKE SYSTEM
Your vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications with
the engine off), the brakes will still function. However, the
effort required to brake the vehicle will be much greater
than that required with the power system operating.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
If either of the two hydraulic systems lose normal capabil-
ity, the remaining system will still function with some loss
of overall braking effectiveness. This will be evident by
increased pedal travel during application and greater pedal
force required to slow or stop. In addition, if the malfunc-
tion is caused by an internal leak, as the brake fluid in the
master cylinder drops, the “Brake Warning Light” will
light.
WARNING!
Driving a vehicle with the “Brake Warning Light” on is
dangerous. A significant decrease in braking perfor-
mance or vehicle stability during braking may occur. It
will take you longer to stop the vehicle or will make
your vehicle harder to control. You could have a
collision. Have the vehicle checked immediately.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench.
