2016 JEEP GRAND CHEROKEE SRT Owners Manual

•Off — disables steering wheel mounted paddle shift-
ers.
Stability Control
• Track — modifies traction control to optimize track
performance with the least stability control.
• Sport — turns off traction control and reduces stability
control.
• Street — provides full traction control and full stability
control.
Suspension
• Track — provides the firmest possible suspension
stiffness with the highest amount of comfort trade-off.
• Sport — provides a firmer suspension stiffness with
moderate comfort trade-off. •
Street — provides a balance of suspension stiffness
and ride comfort for typical daily driving.
Steering
• Track — provides the greatest amount of steering
feedback, requiring the highest amount of steering
effort.
• Sport — provides greater steering feedback, requiring
greater steering effort.
• Street — provides a balance of steering feedback and
steering effort.
• DEFAULT MODE — This mode will be activated
automatically when restarting the vehicle unless Valet
mode or ECO mode is active. This mode is for typical
driving conditions where the ABS and Transmission
will be operating in their STREET settings, which
cannot be changed while in this mode. The Steering
5

assist and Suspension (active dampening system) stiff-
ness may be configured to either the STREET, SPORT
or TRACK settings within this mode. Steering wheel
mounted paddle shifters may be enabled or disabled
while in this mode as well.
• VALET MODE — To enter this mode the operator
must select it from the Drive Modes interface and enter
a four digit PIN code. The PIN code is not predeter-
mined, so the operator is free to select any four digit
numeric combination that will be easy to remember.
While in Valet Mode the following vehicle configura-
tions are set and locked to prevent unauthorized
modification:
• Engine limited to a lowest power output state.
• Transmission locks out access to first gear and shifts
earlier than normal. •
Traction, Steering and Suspension are forced to
STREET settings.
• Steering wheel mounted paddle shifters are disabled.
• The SRT Drive Modes are not available. Pushing the
SRT button will display the unlock keypad.
• The ESC Off button is disabled.
• The Launch Control button is disabled.
NOTE:
• To exit VALET Mode the operator must enter the same
four digit PIN that was used to enter the mode. The
unlock keypad can be accessed by either pushing the
SRT button or selecting to disable Valet on the
Uconnect touchscreen.
• The vehicle will restart with VALET active if VALET
was active when the vehicle was last shut down.
488 STARTING AND OPERATING

•ECO MODE — This mode modifies the vehicle’s
engine and transmission settings to provide improved
fuel economy at a trade-off with acceleration perfor-
mance. Increased engine exhaust noise and/or vibra-
tion may be noticed while Eco is active, this is normal
and will not damage the vehicle.
NOTE: Changing the Drive Mode will deactivate Eco.
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 check track 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 transmission are at operating temperature.
• Launch Control is intended to be used on dry, paved
road surfaces only.

STARTING AND OPERATING 489

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 “Understanding
Your Instrument Panel” 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 touch- screen. 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 Driver Informa-
tion Display (DID).
• 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 accelera-
tor 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 DID to inform the
driver if one or more of the above conditions have not
been met.
490 STARTING AND OPERATING

4. When the above conditions have been met, the DIDwill 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 Stabil-
ity 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
NOTE: 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 recommended that your vehicle oper-
ates in SPORT or TRACK modes during the track
event.
5
STARTING AND OPERATING 491

•Prior to each track event/day, verify all fluids are at
the correct levels. Refer to “Fluid Capacities” in “Main-
taining Your Vehicle” for further information.
• Prior to each track event, verify the front and rear
brake pads have more than ½ pad thickness remain-
ing. If the brake pads require changing, please burnish
prior to track outing at full pace.
• At the conclusion of each track event, it is recom-
mended 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.
• If equipped with a removable lower front fascia grille,
it is recommended to remove it for track use during warm/hot weather to improve cooling airflow to
critical powertrain and cooling system components.
• All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion 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 tempera-
tures of the engine, transmission, driveline and brake
system. This may affect noise (NVH) countermeasures
designed into your vehicle. New components may
need to be installed to return the system to the original
NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommend 32psi (221kpa) front,
30psi (207 kpa) rear cold
492 STARTING AND OPERATING

NOTE:It is recommended that you target 40psi (276kpa)
Hot Tire Pressure at the conclusion of each track session.
Starting at 32psi (221kpa) Front & 30psi (207 kpa) Rear
Cold and adjusting based on ambient & track conditions
is recommended. Tire pressure can be monitored via the
Driver Information Display (DID) 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 com-
ponents 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.
2. Lap the track in this manner until you start smelling the brakes. Continue for another ½ lap at speed, then do a two lap cool down with minimal brake applies.
Make sure the brakes are not smoking. If they are, do
another cool down lap.
3. Do not continue for more than 1 full burnishing lap after you start smelling the brakes. Do not get them
smoking heavily. This will get them too hot and affect
their life negatively in future track use.
4. Allow vehicle to sit and cool in the paddock for at least 30 min. If an infrared thermal gun is available, allow
rotors to cool to 200°F (93.3°C) before going back out.
5. There should be a thin, ash layer when inspecting the pads installed in the caliper. Having the ash layer go
more than half the thickness of the pad material
indicates too aggressive of a burnish.
5
STARTING AND OPERATING 493

6. Sometimes, a second burnish session is required. If thepads start smelling in the next track session, reduce
speed and braking decel to burnish targets and follow
step 2-4.
7. New pads installed on old rotors still need to be burnished. New rotors installed with old pads should
be burnished at the track or street driven for 300 city
miles to develop an adequate lining transfer layer on
the rotor surface prior to track use.
8. Rotors that pulsate during track use should be re- placed. Resurfacing of the rotors is not recommended,
as it removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, mak-
ing it less robust and increasing the likelihood of
pulsation in further track use.DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
CAUTION!
•Due to lower ground clearance, driving your ve-
hicle up steep driveways, approach ramps or near
parking blocks may cause damage to the front
fascia and ground effects.
• Driving through snow more than 4 inches (100 mm)
deep may cause damage to the front fascia and
ground effects.
