climate control JEEP GRAND CHEROKEE LIMITED 2018 Owners Manual

The Remote Starting System also activates the Climate
Control, vented seats (if equipped) in temperatures above
80° F (26.7° C), and the optional heated seats, and optional
heated steering wheel in temperatures below 40° F (4.4° C).
Refer to “Seats” in “Getting To Know Your Vehicle” for
further information.
NOTE:
•The vehicle must be equipped with an automatic trans-
mission to be equipped with Remote Start.
• Obstructions between the vehicle and key fob may
reduce this range.

WARNING!(Continued)
•Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting in
a seat that has been overheated could cause serious
burns due to the increased surface temperature of the
seat.
Front Ventilated Seats — If Equipped
Located in the seat cushion and seat back are fans that
draw the air from the passenger compartment and move
air through fine perforations in the seat cover to help keep
the driver and front passenger cooler in higher ambient
temperatures. The fans operate at two speeds, HI and LO.
The front ventilated seats control buttons are located
within the Uconnect system. You can gain access to the
control buttons through the climate screen or the controls
screen. •
Press the ventilated seat button

WARNING!
Do not adjust the steering column while driving.
Adjusting the steering column while driving or driv-
ing with the steering column unlocked, could cause the
driver to lose control of the vehicle. Failure to follow
this warning may result in serious injury or death.
Heated Steering Wheel — If Equipped
The steering wheel contains a heating element that helps
warm your hands in cold weather. The heated steering
wheel has only one temperature setting. Once the heated
steering wheel has been turned on, it will operate for an
average of 80 minutes or more before automatically shut-
ting off. This time may vary depending on the temperature
of the environment. The heated steering wheel can shut
off early or may not turn on when the steering wheel is
already warm.
The heated steering wheel control button is located within
the Uconnect system. You can gain access to the control
button through the climate screen or the controls screen.
•Press the heated steering wheel button

For vehicles not equipped with an instrument cluster
display, perform the following steps:
1.
Center the steering wheel (front wheels pointing straight
forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-halfturn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.

TIRE QUALITY GRADES
The following tire grading categories were established
by the National Highway Traffic Safety Administration.
The specific grade rating assigned by the tire’s manu-
facturer in each category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must conform to Federal
safety requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.Traction Grades
The Traction grades, from highest to lowest, are AA, A,
B, and C. These grades represent the tire’s ability to stop
on wet pavement, as measured under controlled condi-
tions on specified government test surfaces of asphalt
and concrete. A tire marked C may have poor traction
performance.
