power steering LINCOLN MKS 2012 User Guide

Using ABS
When hard braking is required, apply continuous force on the brake
pedal. Do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.
Brake assist
The brake assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and uses the
ABS system to achieve maximum braking pressure. Once a panic brake
application is detected, the system will remain activated as long as the
brake pedal is pressed or ABS is engaged. The system is deactivated by
either releasing the brake pedal or coming to a complete stop. When the
system activates, noise from the ABS pump motor and brake pedal
pulsation may be observed; this is normal.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is switched on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS is disabled due to a malfunction and needs to be serviced.
Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
Brake over accelerator
This vehicle is equipped with a brake over accelerator feature. In the
event the accelerator pedal becomes stuck or entrapped, applying steady
and firm pressure to the brake pedal will both slow the vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to P
(Park) and apply the parking brake, and then inspect the accelerator
pedal for any interferences. If none are found and the condition persists,
have your vehicle towed to the nearest authorized dealer.

STEERING
3.5L EcoBoost™ engine (if equipped):Your vehicle is equipped with
an Electric Power Steering (EPS) system. There is no fluid reservoir to
check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it takes
for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin the
Instrument Clusterchapter for more information.
WARNING:The EPS system has diagnostics checks that
continuously monitor the EPS system to ensure proper operation
of the electronic system. When an electronic error is detected, the
message POWER STEERING ASSIST FAULT will be displayed in the
message center. If this happens, stop the vehicle in a safe place, and
turn off the engine. After at least 10 seconds, reset the system by
restarting the engine, and watch the message center for POWER
STEERING ASSIST FAULT. If the message returns, or returns while
driving, take the vehicle to your dealer to have it checked. With the
message displayed, the steering assist is turned off, making the vehicle
harder to steer.
WARNING:If the message SERVICE POWER STEERING is
displayed in the message center, the EPS system has detected a
problem with the system function. On the next key cycle the message
SERVICE POWER STEERING NOW will be displayed and steering
assist will be removed until the steering system is serviced. Have your
vehicle taken to the nearest dealer as soon as possible.
3.7L V6 Duratecengine:Your vehicle is equipped with a hydraulic
steering system.

To help prevent damage to the power steering system, never hold the
steering wheel at its furthest turning points (until it stops) for more than
a few seconds when the engine is running. If the power steering system
breaks down (or if the engine is turned off), you can steer the vehicle
manually, but it takes more effort.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the steering wanders or pulls equipped with either EPS or hydraulic
steering system, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
WARNING:Obtain immediate service if a system error is
detected. You may not notice any difference in the feel of your
steering, but a serious condition may exist. Failure to do so may result
in loss of steering control.
BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is applied. If you cannot move
the gearshift lever out of P (Park) when the ignition is on and the brake
pedal applied, it is possible that a fuse has blown or the vehicle’s brake
lamps are not operating properly. Refer toFuses and relaysin the
Roadside Emergencieschapter.

•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
AWD systems (if equipped)
AWD uses all four wheels to power the vehicle. This increases traction,
enabling you to drive over terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
When driving at slow speeds in deep sand under high outside
temperatures, use a low gear when possible. Lower gear operation will
maximize the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to
protect overheating of the engine.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.
When driving through water, determine the depth; avoid water higher
than the bottom of the wheel rims (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even AWD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the engine, transmission, AWD system components or axles are
submerged in water, their fluids should be checked and changed, if
necessary.

Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. The front wheels have
to be turning in order to steer the
vehicle.
Your vehicle has anti-lock brakes, therefore apply the brakes steadily. Do
not “pump” the brakes.
Driving on snow and ice
Note:Excessive tire slippage can cause transmission damage.
AWD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although an AWD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, apply the brake steadily. Since
your vehicle is equipped with a four wheel anti-lock brake system (ABS),
do not “pump” the brakes. Refer to theBrakessection of this chapter
for additional information on the operation of the anti-lock brake system.
WARNING:If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.

How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature gauge will move to the red (hot)
area.
•The coolant temperature warning light
will illuminate.
•The service engine soon
indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will have limited power, will not be
able to maintain high-speed operation, and may completely shut down
without warning, potentially losing engine power, power steering assist,
and power brake assist, which may increase the possibility of a crash
resulting in serious injury.

The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
POWER STEERING FLUID (EXCEPT ECOBOOST ENGINE)
Refer toscheduled maintenance information.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer toMaintenance
product specifications and capacitiesin this chapter for the proper
fluid type.
