tire size JEEP COMPASS 2016 1.G User Guide

If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable.
However, see an authorized dealer immediately. If the light is flashing when the engine
is running, immediate service is required, and you may experience reduced perfor-
mance, an elevated/rough idle or engine stall, and your vehicle may require towing.
– Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires).
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more
of your tires is significantly under-inflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires as soon as possible and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the tire
to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and
tire tread life and may affect the vehicle’s handling and stopping ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE
AIR PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE
PLACARD OR TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
AFTER INFLATION, THE VEHICLE MAY NEED TO BE DRIVEN FOR 20 MINUTES
BEFORE THE FLASHING LIGHT WILL TURN OFF.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function properly.

NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C), and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a TPMS, as damage to the sensors
may result.
– Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on, it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is a problem with the brake
system master cylinder reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS) are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

WARNING!
• Overloading of your tires is dangerous. Overloading can cause tire failure,affect vehicle handling, and increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never overload them.
• Improperly inflated tires are dangerous and can cause collisions. Under-
inflation increases tire flexing and can result in over-heating and tire failure.
Over-inflation reduces a tire’s ability to cushion shock. Objects on the road and
chuck holes can cause damage that results in tire failure. Unequal tire
pressures can cause steering problems. You could lose control of your vehicle.
Over-inflated or under-inflated tires can affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control. Always drive with each tire
inflated to the recommended cold tire inflation pressure.
SPARE TIRES — IF EQUIPPED
NOTE:
For vehicles equipped with Tire Service Kit instead of a spare tire, please refer to “Tire
Service Kit” in “What To Do In Emergencies” on your DVD for further information.
CAUTION!
Because of the reduced ground clearance, do not take your vehicle through an
automatic car wash with a compact or limited-use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original Equipped Tire And Wheel — If Equipped
Your vehicle may be equipped with a spare tire and wheel equivalent in look and
function to the original equipment tire and wheel found on the front or rear axle of
your vehicle. This spare tire may be used in the tire rotation for your vehicle. If your
vehicle has this option, refer to an authorized tire dealer for the recommended tire
rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use only. You can identify if your
vehicle is equipped with a compact spare by looking at the spare tire description on
the Tire and Loading Information Placard located on the driver’s side door opening or
on the sidewall of the tire. Compact spare tire descriptions begin with the letter “T”
or “S” preceding the size designation. Example: T145/80D18 103M.

Do not install a wheel cover or attempt to mount a conventional tire on the compact
spare wheel, since the wheel is designed specifically for the compact spare tire. Do
not install more than one compact spare tire and wheel on the vehicle at any given
time.
WARNING!
Compact spares are for temporary emergency use only. With these spares, do not
drive more than 50 mph (80 km/h). Temporary use spares have limited tread life.
When the tread is worn to the tread wear indicators, the temporary use spare tire
needs to be replaced. Be sure to follow the warnings, which apply to your spare.
Failure to do so could result in spare tire failure and loss of vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only. This tire may look like the
originally equipped tire on the front or rear axle of your vehicle, but it is not. This
spare tire may have limited tread life. When the tread is worn to the tread wear
indicators, the temporary use full size spare tire needs to be replaced. Since it is not
the same as your original equipment tire, replace (or repair) the original equipment
tire and reinstall on the vehicle at the first opportunity.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency use only. This tire is identified
by a label located on the limited-use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the original equipped tire on the front
or rear axle of your vehicle, but it is not. Installation of this limited-use spare tire
affects vehicle handling. Since it is not the same as your original equipment tire,
replace (or repair) the original equipment tire and reinstall on the vehicle at the first
opportunity.
WARNING!
Limited-use spares are for emergency use only. Installation of this limited-use
spare tire affects vehicle handling. With this tire, do not drive more than the speed
listed on the limit-use spare wheel. Keep inflated to the cold tire inflation
pressures listed on your Tire and Loading Information Placard located on the
driver’s side B-Pillar or the rear edge of the driver’s side door. Replace (or repair)
the original equipment tire at the first opportunity and reinstall it on your vehicle.
Failure to do so could result in loss of vehicle control.
