2017 JEEP GRAND CHEROKEE display

SRT Drive ModesYour SRT vehicle is equipped with a Drive Modes feature which allows
for coordinating the operation of various vehicle systems depending
upon the type of driving behavior desired. The Drive Modes feature is
controlled through the Selec-Track switch and may be accessed by
performing any of the following:
• Pushing the SRT button on the Selec-Track switch.
• Selecting “Drive Modes” from the “Apps” menu.
• Selecting “Drive Modes” from within the Performance Pages menu.
The SRT Drive Modes main screen displays the current drive mode and
real-time status of the vehicle’s performance configuration. The select-
able Drive Modes are Track, Sport, Auto, Snow, Tow or Custom.
Information shown will indicate the actual status of each system, along
with a vehicle graphic that displays the active drive mode status. The
color red indicates “Track,” orange “Sport,” yellow “Street” and blue
for “Snow.” These features will reset to AUTO upon an ignition cycle. If
the system status shown does not match the current drive mode set up,
a message will be displayed indicating which values are not matching
the current mode.
NOTE:Electronic Stability Control (ESC) Full-Off is only available in
Selec-Track TRACK mode and can be activated by pushing and holding
the ESC Off button on the instrument panel switch bank for five
seconds.

Race Options
Press the “Race Options” button on the touchscreen while in the Drive
Modes screen, to display the vehicle’s Launch Control screen. Within
Race Options, you can activate, deactivate, and adjust the RPM values
for the Launch Control and Shift Light features.
Refer to “Shift Light” in this section for further information on shift
light features.Launch Control
WARNING!
Launch Mode is intended for off-highway or off-road use only and
should not be used on any public roadways. It is recommended that
this feature be used in a controlled environment, and within the
limits of the law. The capabilities of the vehicle as measured by the
performance pages must never be exploited in a reckless or danger-
ous manner, which can jeopardize the user’s safety or the safety of
others. Only a safe, attentive, and skillful driver can prevent acci-
dents.

display. This feature is a visual cue to manually up-shift using the
paddle shifters or shifting the transmission gear selector.To actuate the Shift Light feature, press the “Shift Light” button on the
touchscreen, then press the “Shift Light On” button on the touch-
screen. Activation is shown on the instrument cluster display. Pressing
the “Shift Light RPM Set-Up” button on the touchscreen will take you
to the Shift Light RPM Set-Up screen.
NOTE:
You must be in Paddle Shift Mode, or the transmission gear
selector must be in manual shift in order to activate the shift light.

LAUNCH CONTROL — IF EQUIPPED
This vehicle is equipped with a Launch Control system that is designed
to allow the driver to achieve maximum vehicle acceleration in a
straight line. Launch Control is a form of traction control that manages
tire slip while launching the vehicle. This feature is intended for use
during race events on a closed course where consistent quarter mile
and zero to sixty times are desired. The system is not intended to
compensate for lack of driver experience or familiarity with the race
track. Use of this feature in low traction (cold, wet, gravel, etc.)
conditions may results in excess wheel slip outside this systems control
resulting in an aborted launch.
Preconditions:
• Launch Control should not be used on public roads. Always checktrack conditions and the surrounding area.
• Launch Control is not available within the first 500 miles (805 km) of engine break-in.
• Launch Control should only be used when the engine and transmis- sion are at operating temperature.
•
Launch Control is intended to be used on dry, paved road surfaces only.
CAUTION!
Use on slippery or loose surfaces may cause damage to vehicle
components and is not recommended. Launch Control is only available when the following procedure is
followed:
NOTE:
Pushing the SRT button on the Select-Track switch or pressing
the “Apps” button on the touchscreen are the two options to access
launch control features. Please refer to “SRT Drive Modes” in “Multi-
media” for further information.
1. Press the “Race Options” button on the touchscreen or push the LAUNCH button on the Select-Track switch.
2. Press the “Launch RPM Set-Up” button on the touchscreen. This screen will allow you to adjust your launch RPM’s for optimum
launch/traction.
3. Press the “Activate Launch Control” button on the touchscreen, follow instructions in the instrument cluster display.
• Make sure the vehicle is not moving.
• Put vehicle in first gear.
• Steering wheel must be pointing straight.
• Vehicle must be on level ground.
• Apply Brake Pressure.
• While holding the brake, rapidly apply the accelerator pedal to wide open throttle. The engine speed will hold at the RPM that
was set in the “Launch RPM Set-up” screen.

NOTE:Messages will appear in the instrument cluster display to inform
the driver if one or more of the above conditions have not been met. 4. When the above conditions have been met, the instrument cluster
display will read “Release Brake”.
5. Keep the vehicle pointed straight.
Launch control will be active until the vehicle reaches 62 mph
(100 km/h), at which point the Electronic Stability Control (ESC)
system will return to its current ESC mode.
Launch control will abort before launch completion, display “Launch
Aborted” in the cluster under any the following conditions:
• The accelerator pedal is released during launch.
• The ESC system detects that the vehicle is no longer moving in a straight line.
• The “ESC OFF” button is pressed to change the system to another mode.
NOTE: After launch control has been aborted, ESC will return to its
current ESC mode.
CAUTION!
Do not attempt to shift when the drive wheels are spinning and do
not have traction. Damage to the transmission may occur.

Guidelines For Track Use
CAUTION!
Because of the extreme conditions encountered during track use,
any damage or wear associated with track use is not covered by
warranty.
• If your SRT vehicle is equipped with Drive Modes they will alter the vehicle’s performance in various driving situations. It is recom-
mended that your vehicle operates in SPORT or TRACK modes
during the track event.
• Prior to each track event/day, verify all fluids are at the correct levels. Refer to “Fluid Capacities” in “Technical Specifications” for
further information.
• Prior to each track event, verify the front and rear brake pads have more than ½ pad thickness remaining. If the brake pads require
changing, please burnish prior to track outing at full pace.
• At the conclusion of each track event, it is recommended that a brake bleed procedure is performed to maintain the pedal feel and
stopping capability of your Brembo High Performance brake system.
• It is recommended that each track outing should end with a minimum of 1 cool down lap using minimal braking. • All SRT vehicles are track tested for 24 hours of endurance,
however, it is recommended that suspension system, brake system,
prop shaft, and ½ shaft boots should be checked for wear or damage
after every track event.
• Track usage results in increased operating temperatures of the engine, transmission, driveline and brake system. This may affect
Noise Vibration Harshness (NVH) countermeasures designed into
your vehicle. New components may need to be installed to return the
system to the original NVH performance.
• Tire pressure: – Below 42 psi (289 kpa) hot and 33 psi (227 kpa) cold recom-
mended.
NOTE: It is recommended that you target below 42 psi (289 kpa) Hot
Tire Pressure at the conclusion of each track session. Starting at 33 psi
(227 kpa) Cold and adjusting based on ambient & track conditions is
recommended. Tire pressure can be monitored via the instrument
cluster display and can assist with adjustments.
Track burnishing your brakes:
To avoid “green lining fade” during track use, the brake pads and rotors
must have a thermal burnish for factory installed components or when
new brake friction components are installed:
1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately 0.60 - 0.80g max without ABS intervention.
