WHAT IS HILL DESCENT
CONTROL
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep slopes in various surfaceconditions.
HOW DOES HILL DESCENT
CONTROL WORK
Hill descent control can maintain vehiclespeeds on downhill slopes between2–20 mph (3–32 km/h). Above 20 mph(32 km/h), the system remains on but thedescent speed cannot be set ormaintained.
Note:The system does not function below2 mph (3 km/h).
The system requires a cool down intervalafter a period of sustained use. Hill descentcontrol provides a warning in the messagecenter when the system is about todisengage for cooling. At this time,manually apply the brakes as needed tomaintain descent speed.
Note:The amount of time that the systemcan remain active before cooling varies withconditions.
HILL DESCENT CONTROL

HYDRAULIC POWER
STEERING
HYDRAULIC POWER STEERINGGUIDELINES
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped)
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the ignition off. After at least 10seconds, switch the ignition on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.

The electronic torque overlay steeringsystem adds supplemental steering assistto the hydraulic gear when needed,dependent on vehicle conditions such asvehicle speed, steering wheel angle, andsteering wheel torque. The hydraulicsteering system provides the majority ofsteering assistance. The electronic torqueoverlay enables features such as pro trailerbackup assistance and lane departurewarning.
If your vehicle loses electrical power whileyou are driving, your vehicle loses electricpower steering assistance. The steeringsystem still operates, and you can steeryour vehicle with hydraulic assist. Steeringyour vehicle with only hydraulic assistrequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage tothe steering system. You do not lose theability to steer your vehicle manually.Typical steering and driving maneuversallow the system to cool and return tonormal operation.
LOCATING THE HYDRAULICPOWER STEERING FLUIDRESERVOIR
The hydraulic power steering fluid reservoiris found in the engine compartment. SeeUnder Hood Overview (page 441).
CHECKING THE HYDRAULICPOWER STEERING FLUID
Check the power steering fluid. SeeScheduled Maintenance (page 591). Ifadding fluid is necessary, use onlyMERCON LV ATF.
Check the fluid level when it is at ambienttemperature.
1.Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3.Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5.Switch the engine off.
6.Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7.If the fluid is low, add fluid in smallamounts, continuously checking thelevel until it is between the MIN andMAX range. For proper fluid type, SeeCapacities and Specifications (page520). Be sure to put the cap back on thereservoir.
