2013 JEEP GRAND CHEROKEE traction control

WARNING!
•The BAS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase the traction afforded by
prevailing road conditions.
• The BAS cannot prevent collisions, includ-
ing those resulting from excessive speed
in turns, driving on very slippery surfaces,
or hydroplaning.
•
The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others.
Electronic Roll Mitigation (ERM)This system anticipates the potential for wheel
lift by monitoring the driver’s steering wheel
input and the speed of the vehicle. When ERM
determines that the rate of change of the steer-
ing wheel angle and vehicle’s speed are suffi-
cient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce engine power to lessen the chance that
wheel lift will occur. ERM will only intervene
during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving ma-
neuvers. It cannot prevent wheel lift due to other
factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading, road
conditions, and driving conditions, influence
the chance that wheel lift or rollover may
occur. ERM cannot prevent all wheel lift or
rollovers, especially those that involve leav-
ing the roadway or striking objects or other
vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in
a reckless or dangerous manner, which
could jeopardize the user’s safety or the
safety of others.
Electronic Stability Control (ESC)This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the oversteer or understeer con-
dition. Engine power may also be reduced to
help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
• Understeer - when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.

The “ESC Activation/Malfunction Indicator Light”
located in the instrument cluster will start to flash
as soon as the tires lose traction and the ESC
system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the
TCS is active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during accelera-
tion, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) can-
not prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi-
tions. ESC cannot prevent collisions, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent col-
lisions resulting from loss of vehicle control
due to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skillful

WARNING!(Continued)
driver can prevent collisions. The capabilities
of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or
the safety of others.
The ESC system has two available operating
modes in 4WD HIGH range and two-wheel
drive vehicles, and one operating mode in 4WD
LOW range.
High Range (Four-Wheel Drive Models)
On
This is the normal operating mode for ESC in
4WD HIGH range. Whenever the vehicle is
started or the transfer case (if equipped) is
shifted from 4WD LOW range or NEUTRAL
back to 4WD HIGH range, the ESC system will
be in this “On” mode. This mode should be used
for most driving situations. ESC should only be
turned to “Partial Off” mode for specific reasons
as noted below. Partial Off
This mode is entered by momentarily pressing
the “ESC OFF” switch. When in “Partial Off”
mode, the TCS portion of ESC, except for the
BLD feature described in the TCS section, has
been disabled and the “ESC Off Indicator Light”
will be illuminated. All other stability features of
ESC function normally. This mode is intended to
be used if the vehicle is in deep snow, sand, or
gravel conditions and more wheel spin than
ESC would normally allow is required to gain
traction. To turn ESC on again, momentarily
press the “ESC OFF” switch. This will restore
the normal “ESC On” mode of operation.
When in “Partial Off” mode, the TCS functional-
ity of ESC, (except for the limited slip feature
described in the TCS section), has been dis-
abled and the “ESC Off Indicator Light” will be
illuminated. All other stability features of ESC
function normally. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
254

NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or starting off in deep
snow, sand, or gravel, it may be desirable to
switch to the “Partial Off” mode by pressing
the “ESC OFF” switch. Once the situation
requiring ESC to be switched to the “Partial
Off” mode is overcome, turn ESC back on by
momentarily pressing the “ESC OFF”
switch. This may be done while the vehicle
is in motion.
WARNING!
•When in "Partial Off" mode, the TCS func-
tionality of ESC, (except for the limited slip
feature described in the TCS section), has
been disabled and the "ESC Off Indicator
Light" will be illuminated. When in "Partial
Off" mode, the engine power reduction
feature of TCS is disabled, and the en-
hanced vehicle stability offered by the ESC
system is reduced.
• Trailer Sway control (TSC) is disabled
when the ESC system is in the "Partial Off"
mode.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in
4WD LOW range. Whenever the vehicle is
started in 4WD LOW range, or the transfer case
(if equipped) is shifted from 4WD HIGH range or
NEUTRAL to 4WD LOW range, the ESC sys-
tem will be in the “Partial Off” mode.Trailer Sway Control (TSC)TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and
apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will
become active automatically once an exces-
sively swaying trailer is recognized. No driver
action is required. Note that TSC cannot stop all
trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Tow-
ing” in “Starting and Operating” for further infor-
mation. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash,
the engine power may be reduced and you may
feel the brakes being applied to individual
wheels to attempt to stop the trailer from sway-
ing. TSC is disabled when the ESC system is in
the “Partial Off” mode.
ESC OFF Switch
255

The “ESC Activation/Malfunction Indicator Light”
(located in the instrument cluster) starts to flash
as soon as the tires lose traction and the ESC
system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when
TCS is active. If the “ESC Activation/Malfunction
Indicator Light” begins to flash during accelera-
tion, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
NOTE:
•The “ESC Activation/Malfunction Indica-
tor Light” and the “ESC OFF Indicator
Light” come on momentarily each time
the ignition switch is turned ON.
• Each time the ignition is turned ON, the
ESC system will be ON even if it was
turned off previously.
• The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indi-
cates the Electronic Stability Control
(ESC) is off.
TIRES — GENERAL
INFORMATION
Tire PressureProper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Three primary areas are affected by improper
tire pressure:
Safety
WARNING!
•Improperly inflated tires are dangerous
and can cause collisions.
• Under-inflation increases tire flexing and
can result in over-heating and tire failure.
(Continued)
WARNING!(Continued)
•Over-inflation reduces a tire’s ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.
• Over-inflated or under-inflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven
wear patterns to develop across the tire tread.
These abnormal wear patterns will reduce tread
life resulting in a need for earlier tire replace-
ment. Under-inflation also increases tire rolling
resistance resulting in higher fuel consumption.
259

WARNING!(Continued)
•Never use a tire with a smaller load index
or capacity, other than what was originally
equipped on your vehicle. Using a tire with
a smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can re-
sult in sudden tire failure and loss of ve-
hicle control.
CAUTION!
Replacing original tires with tires of a differ-
ent size may result in false speedometer and
odometer readings.
TIRE CHAINS (TRACTION
DEVICES)
Use of traction devices require sufficient tire-to-
body clearance. Follow these recommenda-
tions to guard against damage.
• Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
• Install on Rear Tires Only
• Due to limited clearance, use reduced size
snow chains or traction devices with a maxi-
mum projection of 6 mm beyond the tire
profile.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can cause
unpredictable handling. You could lose control
and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
•Because of restricted traction device clear-
ance between tires and other suspension
components, it is important that only trac-
tion devices in good condition are used.
Broken devices can cause serious dam-
age. Stop the vehicle immediately if noise
occurs that could indicate device break-
age. Remove the damaged parts of the
device before further use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
• Do not drive for prolonged period on dry
pavement.
