2015 JEEP CHEROKEE 4wd service light

•Electronic Throttle Control (ETC) Light
This light informs you of a problem with
the Electronic Throttle Control (ETC) sys-
tem. The light will come on when the
ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an
authorized dealer.
If a problem is detected, the light will come on while
the engine is running. Cycle the ignition key 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 for service as soon as possible. If
the light is flashing when the engine is running,
immediate service is required. You may experience
reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.
•Oil Temperature Warning Light
This telltale indicates engine oil tempera-
ture is high. If the light turns on while
driving, stop the vehicle and shut off the
engine as soon as possible.
•Secondary Air Bag Warning Light
If the light turns on while driving, have the
system inspected at an authorized dealer as
soon as possible. Refer to “Occupant Re-
straints” in “Things To Know Before Start-
ing Your Vehicle” for further information.

and rear wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide in-
creased torque at the wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
15. SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your authorized
dealer as soon as possible.
16. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
