traction control FORD EDGE 2011 1.G User Guide

The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Press the parking brake pedal downward again to release the parking
brake. Driving with the parking brake on will cause the brakes to wear
out quickly and reduce fuel economy.
Note:If the vehicle is driven with the parking brake applied, a chime
will sound.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSCsystem provides the following stability
enhancement features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
•Roll Stability Control™ (RSC), which functions to help avoid a
vehicle roll-over.
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. Install any aftermarket stereo
loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.

WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracwith RSCsystem is an indication that
at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTracwith RSCsystem
activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracwith RSCsystem, the stability control light and
stability control off light will illuminate steadily. Verify that the
AdvanceTracwith RSCsystem was not manually disabled through
the message center. If the stability control light and stability control off
light still illuminate steadily, have the system serviced by an authorized
dealer immediately. Operating your vehicle with AdvanceTracwith
RSCdisabled could lead to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.
The AdvanceTracwith RSC
system includes a traction control
off selection located in the message
center, a stability control light and a
stability control off light in the instrument cluster. Refer toMessage
centerin theInstrument clustersection for more information. Both the
stability control light and the stability control off light will illuminate
temporarily during start-up as part of a normal system self-check. The
stability control light may illuminate (flash) during certain driving
conditions which cause the AdvanceTracwith RSCsystem to operate.
If the stability control light and stability control off light illuminate
steadily, have the system serviced by an authorized dealer immediately.
The message center will also indicate a failure with the AdvanceTrac
with RSCsystem.

When AdvanceTracwith RSCperforms a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracwith RSCyou may
experience the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction control system (TCS)
Traction control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem; engine traction control and brake traction
control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction control is most active at low speeds.
During traction control events, the stability control light in the
instrument cluster will flash.
If the traction control system is activated excessively in a short period of
time, the braking portion of the system may become temporarily disabled
to allow the brakes to cool down. In this situation, traction control will
use only engine power reduction or transfer to help control the wheels
from over-spinning. When the brakes have cooled down, the system will
regain all features. Anti-lock braking, RSC, and ESC are not affected by
this condition and will continue to function during the cool-down period.
The engine traction control and brake traction control system may be
deactivated in certain situations. See theSwitching off AdvanceTrac
with RSCsection below.

Switching off AdvanceTracwith RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTracwith RSC
system may be beneficial because the wheels are allowed to spin. This
will restore full engine power and will enhance momentum through the
obstacle.
To switch off the AdvanceTracwith RSCsystem, select traction
control off in the message center. Full features of the AdvanceTracwith
RSCsystem can be restored by selecting traction control on, or by
turning off and restarting the engine.
If you switch off the AdvanceTrac
with RSCsystem, the stability
control off light will illuminate
steadily. Selecting traction control
on will turn off the stability control
light.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function. However, ESC and RSCare
disabled.

WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
•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)
With AWD, the vehicle 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.
Do not drive your AWD vehicle in deep sand for an extended period of
time. This will cause the AWD system to overheat. If the rear tires stop
spinning while the front tires spin in deep sand, turn off the vehicle and
allow the AWD system to cool down for a minimum of 15 minutes. After
Driving
284

USA(fus)

the system has cooled down, normal AWD function will return. When
driving at slow speeds in deep sand under high outside temperatures,
use L (Low) gear when possible. L (Low) 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 (for cars) or the bottom of the hubs
(for trucks) (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.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant and
PTU (power transfer unit) lubricant should be checked and changed if
necessary.

Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Avoid driving crosswise or turning on steep
slopes or hills.A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill, start in a lower gear rather than
downshifting to a lower gear from a higher gear once the ascent has
started. This reduces strain on the engine and the possibility of stalling.
If you do stall out, do not try to turnaround because you might roll over.
It is better to back down to a safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.
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.
