2008 DODGE NITRO Owners Manual

To Set At A Desired Speed
When the vehicle has reached the desired speed, press
down on the lever and release. Release the accelerator
and the vehicle will operate at the selected speed.
NOTE:The vehicle should be traveling at a steady
speed and on level ground before pressing the SET lever.
To Deactivate
A soft tap on the brake pedal, pulling the speed control
lever towards you ªCANCELº, or normal brake or clutch
pressure while slowing the vehicle will deactivate speed
control without erasing the set speed memory. Pressing
the ON/OFF button or turning off the ignition switch
erases the set speed memory.
To Resume Speed
To resume a previously set speed, push the ªRESUME
ACCELº lever up and release. Resume can be used at any
speed above 25 mph (40 km/h).
To Vary The Speed Setting
When the speed control is ON, speed can be increased by
pushing up and holding ªRESUME ACCELº. Release the
lever when the desired speed is reached, and the new
speed will be set.
Tapping ªRESUME ACCELº once will result ina1mph
(2 km/h) speed increase. Each time the lever is tapped,
speed increases so that tapping the lever three times will
increase speed by 3 mph (6 km/h), etc.
To decrease speed while speed control is ON, push down
and hold ªSET DECELº. Release the lever when the
desired speed is reached, and the new speed will be set.

Tapping the ªSET DECELº button once will result in a 1
mph (2 km/h) speed decrease. Each time the button is
tapped, speed decreases.
NOTE:The Speed Control system has been designed to
shut down if multiple speed control switch functions are
operated simultaneously in order to ensure proper op-
eration. If this occurs, the system can be reactivated by
pushing the speed control switch ON/OFF button and
re-setting the desired vehicle SET speed.
Manual Transmission
Depressing the clutch pedal will disengage the speed
control. A slight increase in engine RPM before the speed
control disengages is normal.
Vehicles equipped with manual transmissions may need
to be shifted into a lower gear to climb hills without
speed loss.
WARNING!
Speed Control can be dangerous where the system
can't maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Don't use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.
To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
NOTE:The speed control system maintains speed up
and down hills. A slight speed change on moderate hills
is normal.
130 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

On steep hills a greater speed loss or gain may occur so
it may be preferable to drive without speed control.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), ERM (Electronic Roll Mitigation) and ESP
(Electronic Stability Program). All five systems work
together to enhance vehicle stability and control in vari-
ous driving conditions are commonly referred to as ESP.
ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to ªAnti-Lock Brake Systemº in Section 5 of this
manual for more information about ABS.
WARNING!
ABS (Anti-Lock Brake System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ABS cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ABS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user's safety or the safety of others.

TCS (Traction Control System)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in the
ªPartial Offº mode. Refer to ªESP (Electronic Stability
Program)º in this section.
BAS (Brake Assist System)
The BAS is designed to optimize the vehicle's braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.
132 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
BAS (Brake Assist System) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor can
it increase the traction afforded by prevailing road
conditions. BAS cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. Only a
safe, attentive, and skillful driver can prevent acci-
dents. 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.
ERM (Electronic Roll Mitigation)
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 steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may 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 maneuvers. It
can not 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 condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM can not
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user's safety or the safety of others.
ESP (Electronic Stability Program)
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.
134 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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
The9ESP/TCS Indicator Light9located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The9ESP/TCS Indicator Light9also
flashes when TCS is active. If the9ESP/TCS Indicator
Light9begins 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!
ESP (Electronic Stability Program) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESP cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESP-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user's safety or the safety of others.
The ESP system has 2 available operating modes in 2WD,
4WD Part Time, 4WD Full Time, and on 2WD vehicles.

ESP On
This is the normal operating mode for ESP in 2WD, 4WD
Part Time, 4WD Full Time, and on 2WD vehicles. When-
ever the vehicle is started, the ESP system will be in this
mode. This mode should be used for most all driving
situations. ESP should only be turned off for specific
reasons as noted below.
Partial Off
This mode is entered by momentarily depressing the
ªESP OFFº switch (located in the center stack lower
switch bank). When in ªPartial Offº mode, the TCS
portion of ESP, except for the ªlimited slipº feature
described in the TCS section, has been disabled and the
ªESP/TCS Indicator Lightº will be illuminated. All other
stability features of ESP 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 ESP would
normally allow is required to gain traction. To turn ESPon again, momentarily depress the ªESP OFFº switch.
This will restore the normal ªESP Onº mode of operation.
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 ªESP OFFº switch. Once the
