2007 DODGE DURANGO power steering

If for some reason, the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and does not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short period of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and does not in any
way damage the steering system.WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the
end of the steering wheel travel will increase the
steering fluid temperature and should be avoided
when possible. Damage to the power steering pump
may occur.
274 STARTING AND OPERATING

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 acci-
dents.
•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.
278 STARTING AND OPERATING

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.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
TheESP/TCS Indicator Lightstarts 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 TSC
(Trailer Sway Control) system activates. If theESP/TCS
Indicator Lightbegins 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.

Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
The ball joints and seals should be inspected whenever
the vehicle is serviced for other reasons. Damaged seals
should be replaced to prevent leakage or contamination
of the grease.

•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Emission Related Components
Fuel System Hoses And Vapor/Vacuum Harnesses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasions, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be given to examining hose surfaces
nearest to high heat sources, such as the exhaust mani-
fold.
Insure nylon tubing in these areas has not melted or
collapsed.Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations to
ease the assembly of hoses to couplings. Therefore, oil
wetness at the hose-coupling area is not necessarily an
indication of leakage. Actual dripping of hot fluid when
systems are under pressure (during vehicle operation),
should be noted before hose is replaced based on leakage.
You are urged to use only the manufacturer’s specified
hoses and clamps, or their equivalent in material and
specification, in any fuel system servicing. It is manda-
tory to replace all clamps that have been loosened or
removed during service. Care should be taken in install-
ing new clamps to insure they are properly torqued.
