brake sensor JEEP GRAND CHEROKEE 2012 WK2 / 4.G User Guide

• Push and hold the RES + button to accelerate in 5mph (8 km/h)increments or push and hold the SET – button to decelerate in 5mph
(8 km/h) increments; release the button to save the new set speed.
Resume
• To resume a previously selected set speed in memory, push the RES +button and release.
Cancel
• Push the CANCEL button, or apply the brakes to cancel the set speedand maintain the set speed memory.
• Push the ON/OFF button to turn the system off and erase the set speed memory.
Adaptive Cruise Control (ACC)
• If your vehicle is equipped with adaptive cruise control the controlsoperate exactly the same as the standard cruise control with one
difference. You can set a specified distance you would like to maintain
between you and the vehicle in front of you.
• If the ACC sensor detects a vehicle ahead, ACC will apply limited braking or acceleration automatically to maintain a preset following distance,
while matching the speed of the vehicle ahead.
• If the sensor does not detect a vehicle directly ahead of you, it functions like a standard cruise control system, maintaining the speed you set.
Distance Setting (ACC Only)
• To set or change the distance setting, press the Distance button andrelease. Each time the button is pressed, the distance setting adjusts
between long (3), medium (2), and short (1). The distance setting will
default to the last set mode the next time the vehicle is restarted and the
ACC system is turned on.
• The specified following distance for ACC can be set by varying the distance setting between 3 (long), 2 (medium), and 1 (short). Using this
distance setting and the vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance setting displays in the EVIC.
Mode (ACC Only)
• If desired, the Adaptive Cruise Control mode can be turned off and thesystem can be operated as a standard (fixed speed) Cruise Control.
When in the standard (fixed speed) Cruise Control mode the distance
setting feature will be disabled and the system will maintain the speed
you set.
• To change between the different cruise modes, press the MODE button when the system is in either the OFF, READY or SET state. Pressing of
the MODE button in any state will result in changing to the new Mode in
the OFF state.
• Refer to your Owner's Manual on the DVD for further information.
OPERATING YOUR VEHICLE
31

• Your vehicle has also been equipped with a TPMS malfunction indicatorto 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 each time the vehicle is restarted 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. Aftermarket 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- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the
brake system may have failed. It will take longer to stop the vehicle.
You could have a collision. Have the vehicle checked immediately.
