traction control JEEP GRAND CHEROKEE 2010 Owner handbook (in English)

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 ve-
hicles.
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 leaving
the roadway or striking objects or other ve-
hicles. 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 incounteracting 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 po-
sition.
• Understeer - when the vehicle is turning less
than appropriate for the steering wheel po-
sition.
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 acceleration, ease up on the
accelerator and apply as little throttle as pos- sible. Be sure to adapt your speed and driving
to the prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from act-
ing on the vehicle, nor can it increase the
traction afforded by prevailing road condi-
tions. ESC cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. 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 one operating
mode in 4WD LOW range.
225

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.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.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
system 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
information. 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 toESC OFF Switch

HDC control speed. Conversely, if more speed
is desired during HDC control, the accelerator
pedal will increase vehicle speed in the usual
manner. When either the brake or the accelera-
tor is released, HDC will control the vehicle
back to the original set speed.
HDC Operation in 4WD Low Range
To enable HDC, press the HDC switch or put the
Selec-Terrain™ system in the “ROCK” mode.
The HDC icon will be illuminated in the instru-
ment cluster and HDC will function. If the vehicle
speed goes above 20 mph (32 km/h), the HDC
icon will flash and HDC will not function. To
disable HDC, press the HDC switch.
4WD Low Range Set Speeds
•1st = 1 mph (1.6 km/h)
• 2nd = 2.5 mph (4 km/h)
• 3rd = 4 mph (6 km/h)
• 4th = 5.5 mph (9 km/h)
• 5th or D (Drive) = 7.5 mph (12 km/h)
• REVERS E = 1 mph (1.6 km/h)
• NEUTRAL = 2.5 mph (4 km/h)
• PARK = HDC will not function HDC is intended for low speed off-road driv-
ing only.
At vehicle speeds above 20 mph
(32 km/h), HDC will no longer function. When
the vehicle speed drops below 20 mph
(32 km/h), HDC function will automatically re-
sume and the vehicle speed will return to the
chosen set speed.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for main-
taining a safe vehicle speed.
ESC Activation/Malfunction Indicator
Light and ESC OFF Indicator Light
The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion switch is turned to the ON
position. It should turn off with the
engine running. If the “ESC
Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
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 acceleration, ease up on the
accelerator and apply as little throttle as pos-
sible. 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.

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 breakage.
Remove the damaged parts of the device
before further use.
• Install device as tightly as possible and
then retighten after driving about 0.5 mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
(Continued)
CAUTION!(Continued)
• Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
• Do not drive for prolonged period on dry
pavement.
• Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer’s if it is less than
30 mph (48 km/h).
• Do not use traction devices on a compact
spare tire.
Treadwear IndicatorsThese indicators are narrow strips 1/16 in
(1.6 mm) thick and are found in the tread
pattern grooves.
When the tread pattern is worn down to these
treadwear indicators, the tires should be re-
placed. Overloading your vehicle, long trips in very hot
weather, and driving on bad roads may result in
greater wear.Life of TireThe service life of a tire is dependent upon
varying factors including but not limited to:
•
Driving style
• Tire pressure
• Distance driven
