2018 JEEP COMPASS fuel consumption

The 4WD LOW mode helps to improve the
off-road performance in all modes. To enable
4WD LOW, please follow the steps below:
Enabling 4WD LOW
With the vehicle stationary, the ignition in the
ON/RUN or with the engine running, shift the
transmission into NEUTRAL and push the
button once 4WD LOW. The instrument clus-
ter will display the message "4WD LOW" once
the shift is complete.
NOTE:
• Both LOCK and LOW LEDs will blink and
then become active on the Selec-Terrain
switch until the shift is complete.
• The instrument cluster display will illumi-
nate the "4WD LOW" icon.
Disabling 4WD LOW
To disable the 4WD LOW mode, the vehicle
must be stationary and the transmission
shifted into NEUTRAL. Push the 4WD LOW
button once.SELEC-TERRAIN — IF
EQUIPPED
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains.
Mode Selection Guide
Rotate the Selec-Terrain knob to select the
desired mode.
•AUTO: This four-wheel drive operation is a
continuous operation, is fully automatic
and can be used on and off road. This mode
balances traction to ensure maneuverabil-
ity and acceleration improvement com-
pared to a vehicle with two wheel drive. This
mode also reduces fuel consumption, since
it allows the disconnect of the drive shaft
where conditions permit.

•SNOW: This mode allows you to have greater
stability under conditions of bad weather.
For use on and off road on surfaces with
poor traction, such as roads covered with
snow. When in SNOW mode (depending on
certain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
•SAND: For off-road driving or use on sur-
faces with poor traction, such as dry sand.
The transmission is set to provide maxi-
mum traction.
•MUD: For off-road driving or use on surfaces
with poor traction, such as roads covered by
mud or wet grass.
•ROCK(Trailhawk only): This mode is only
available in 4WD LOW range. The device
sets the vehicle to maximize traction and
allow the highest steering capacity for off-
road surfaces. This mode gives you the
maximum performance off-road. Use for
low speed obstacles such as large rocks,
deep ruts, etc.NOTE:
• Rock mode is only available on the vehicles
equipped with the Off-Road package.
• Activate the Hill Descent Control for steep
downhill control. See “Electronic Brake
Control System” in “Safety” for further
information.
STOP/START SYSTEM — IF
EQUIPPED
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal, clutch pedal or
pressing the accelerator pedal will automati-
cally re-start the engine.
WARNING!
Before opening the hood, make sure that
the engine is off and that the ignition is in
the OFF mode. Follow the indications on
the plate underneath the hood. We recom-
WARNING!
mend that you remove the key fob if other
people remain in the vehicle. The vehicle
should only be exited after the key fob has
been removed and the ignition is on the
OFF mode. During refueling, make sure
that the engine is off (ignition device in the
OFF mode).
CAUTION!
When replacing the battery, always con-
tact your authorized dealer. Replace the
battery with the same type (HEAVY DUTY)
and with the same specifications.
Operating Modes
Engine stopping mode
Models equipped with a manual transmis-
sion:
With the vehicle stopped, the engine stops
with transmission in neutral and clutch pedal
released.

TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
WARNING!
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure.
Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may
cause the vehicle to drift left or right.Fuel EconomyUnderinflated tires will increase tire rolling re-
sistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the left side B-Pillar or rear edge of
the passenger door.
At least once a month:
• Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly
inflated even when they are under-inflated.SERVICING AND MAINTENANCE
