2009 CHRYSLER ASPEN warning light

Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP 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, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The ESP/TCS Indicator Light starts to flash as
soon as the tires lose traction and the TCS or
ESP system becomes active. It will also flash
once a swaying trailer is detected and the
Trailer Sway Control (TSC) system activates. If the ESP/
TCS Indicator Light begins to flash during acceleration,
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!
²ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.

WARNING! (Continued)
²ESP cannot prevent accidents, including those
resulting from excessive speed in turns, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
²The capabilities of an ESP-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 ESP system has two available operating modes.
4WD/4WD LOCK or 2WD Models
ON
This is the normal operating mode for ESP in 4WD LOCK
and in 2WD vehicles. Whenever the vehicle is started or
the transfer case (if equipped) is shifted from 4WD LOW
or NEUTRAL back to 4WD LOCK, the ESP system will bein this mode. This mode should be used for almost all
driving situations. ESP should only be turned to ªPartial
Offº for specific reasons as noted below.
This mode is entered by momentarily
depressing the ESP OFF Control
Switch. When in ªPartial Offº mode,
the engine management portion of
ESP has been desensitized, the thresh-
olds for ESP activation are raised, and
the ªESP/TCS Indicator Lightº will be
illuminated. This mode is intended to
be used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESP would nor-
mally allow is required to gain traction. Trailer Sway
Control (TSC) is not available when the system is in the
9Partial Off9mode. To turn ESP on again, momentarily
depress the ESP OFF Control Switch. This will restore the
normal ON mode of operation. ESP always operates
under braking, even with the switch in the OFF position.
Partial Off
304 STARTING AND OPERATING

WARNING!
In the ªPartial Offº mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the ªPartial Offº
mode by pressing the ESP Control Switch. Once the
situation requiring ESP to be switched to the ªPartial Offº
mode is overcome, turn ESP on by momentarily depress-
ing the ESP Control Switch. This may be done with the
vehicle in motion.
4WD LOW Range
Partial Off
This is the normal operating mode for ESP in 4WD LOW.
Whenever the vehicle is started in 4WD LOW or the
transfer case (if equipped) is shifted from 4WD LOCK or
NEUTRAL to 4WD LOW, the ESP system will be in this
mode. In 4WD LOW, ESP function is desensitized until
the vehicle reaches a speed of 30 mph (48 km/h). At 30
mph (48 km/h) the normal ESP stability function returns
and the ESP/TCS Indicator Light turns off. When the
vehicle speed drops below 25 mph (40 km/h) the ESP
system goes back to Partial Off. ESP is desensitized at low
vehicle speeds in 4WD LOW so that it will not interfere
with off road driving but ESP function returns to provide
the stability feature at speeds above 30 mph (48 km/h).
The ABS is in a special Off Road mode that allows wheels
to lock at lower speeds if gravel is detected to shorten
stopping distances.
STARTING AND OPERATING 305
5

NOTE:When the vehicle is in 4WD LOW, a feature of
the ESP system remains active whether the ESP is on or
off. This feature functions similar to a limited slip differ-
ential and controls the wheel spin across an axle. If one
wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel and
allow more engine torque to be applied to the wheel that
is not spinning.
WARNING!
In the Partial Off mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize a swaying
trailer and will take the appropriate actions to attempt to
stop the sway. The system will reduce engine power andapply individual brakes that will counter act the sway of
the trailer. TSC will become active automatically once the
swaying trailer is recognized. No driver action is re-
quired. TSC cannot stop all trailers from swaying. Al-
ways use caution when towing a trailer and follow the
tongue weight recommendations. For additional infor-
mation on towing a trailer with your vehicle, refer to
9Trailer Towing9in Section 5.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ESP/BAS Warning Light
and the yellow ESP/TCS Indicator Light in the instru-
ment cluster both come on when the ignition switch is
turned to the ON position. They should both go out with
the engine running. If the ESP/BAS Warning Light comes
on continuously with the engine running, a malfunction
has been detected in either the ESP or BAS system, or
both. If this light remains on after several ignition cycles,
306 STARTING AND OPERATING

and the vehicle has been driven several miles at speeds
greater than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
NOTE:
²The ESP Indicator Light and the ESP/BAS Warning
Light come on momentarily each time the ignition
switch is turned ON.
²Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
²The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.
WARNING!
DO NOT use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and
wheel sizes with load ratings approved for your
vehicle.

TIRE PRESSURE MONITOR SYSTEM (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure (the placard is lo-
cated on the driver's side B-pillar).
The tire pressure will vary with temperature by about 1
psi (6.9 kPa) for every 12ÉF (6.5ÉC). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after a vehicle has not been driven for more than
three hours - and in outside ambient temperature.Refer
to the ªTires ± General Informationº in this section for
information on how to properly inflate the vehicle's
tires. The tire pressure will also increase as the vehicle is
driven - this is normal and there should be no adjustment
for this increased pressure.TPMS will warn the driver of a low tire pressure if the tire
pressure falls below the low pressure warning threshold
for any reason, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended
cold placard pressure. Once the low tire pressure warn-
ing has been illuminated, the tire pressure must be
increased to the recommended cold placard pressure in
order for the TPMS warning light to be turned off. The
system will automatically update and the TPMS warning
light p will extinguish once the updated tire pressures
have been received. The vehicle may need to be driven
for up to 10 minutes above 15 mph (25 km/h) to receive
this information.
328 STARTING AND OPERATING

3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Lamp
will flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the TPM Telltale
Lamp will turn OFF, as long as no tire pressure is below
the low-pressure warning limit in any of the four active
road tires. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
Premium System ± If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors tomonitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
²Receiver module
²Four tire pressure monitoring sensors
²Three trigger modules (mounted in three of the four
wheel wells).
²Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and a
graphic displaying tire pressures.
²Yellow Tire Pressure Monitoring Telltale Light.
