ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSC system provides stability enhancement
features such as Roll Stability Control™ (RSC), Electronic Stability
Control (ESC) and Traction Control (TCS) for certain driving situations.
The system includes an AdvanceTracwith RSC on/off button, and a
“sliding car” icon
in the instrument cluster.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTracwith RSC performs a system self-check. During
AdvanceTracwith RSC operation you may experience the following:
•A rumble, grunting, or grinding noise after startup and when driving
off
•A slight deceleration of the vehicle
•The AdvanceTracwith RSC indicator light will flash when the system
is activated.
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
Traction Control
Traction Control helps your vehicle maintain traction, when driving on
slippery and/or hilly road surfaces, by detecting and controlling wheel
spin. Excessive wheel spin is controlled by momentarily reducing engine
power and/or applying the anti-lock brakes. Traction Control is a driver
aid that helps your vehicle.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTracwith RSC system off by pressing the AdvanceTrac
with RSC button momentarily. This will allow your tires to “dig” for
traction. Remember to switch the AdvanceTracwith RSC system back
on once the vehicle is no longer stuck.
If the AdvanceTracwith RSC system is activated excessively in a short
period of time, the brake portion of the system will disable to allow the
brakes to cool down. In this situation, Traction Control will use only
engine power reduction to help control the wheels from over-spinning.
When the brakes have cooled down, the system will again function
normally. Anti-lock braking, RSC and ESC are not affected by this
condition and will function normally during the cool-down period.

Driving conditions that may activate AdvanceTracwith RSC include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
AdvanceTracwith RSC button and functionality
The AdvanceTracwith RSC system automatically turns on each time
the engine is started, even if it was turned off when the engine was last
shut down. The “sliding car” icon
which is located with the warning
lights in the instrument cluster will illuminate during bulb check at initial
start-up and then go off. This tells you that the system is normal and
active. All functions of the AdvanceTracwith RSC (RSC, ESC, Engine
Traction Control, and Brake Traction Control) will be activated at start
up. When the system is left active, the “sliding car” icon
will flash
only when any of the components of the system are affecting the
vehicle’s performance, otherwise the light will remain off. Consequently,
the “sliding car” icon
will not be illuminated during most of your
normal driving.
The AdvanceTracwith RSC button,
located on the center stack of the
instrument panel, allows the driver
to control certain features of the
AdvanceTracwith RSC system
below 25 mph (40 km/h). If the
vehicle is below 25 mph (40 km/h), momentarily pressing the
AdvanceTracwith RSC button will disable RSC, ESC and Engine
Traction Control and steadily illuminate the “sliding car” icon
.
Pressing and holding the AdvanceTracwith RSC button for more than
five seconds will further disable the brake portion of the Traction Control
feature and the “sliding car” icon
will flash momentarily and then
illuminate steady.
If the vehicle is above 25 mph (40 km/h), momentarily pressing the
AdvanceTracwith RSC button will steadily illuminate the “sliding car”
icon
, however, the AdvanceTracwith RSC system will remain
enabled until the vehicle speed drops below 25 mph. If the vehicle speed
decreases below 25 mph (40 km/h), the system will become deactivated,
but if the vehicle speed subsequently increases to above 25 mph (40
km/h), the system will again become active. In general, the system will
be active at all times the vehicle speed is above 25 mph (40 km/h).
In R (Reverse), ABS and the Traction Control feature will continue to
function, however ESC and RSC are disabled.

Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTracwith RSC system.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or death. The occurrence of a AdvanceTracwith RSC event is
an indication that at least some of the tires have exceeded their ability
to grip the road; this may lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Operating your
vehicle with AdvanceTracwith RSC system disabled may severely
reduce your ability to control your vehicle. If you experience a severe
road event or any loss of vehicle control, SLOW DOWN.
If a failure is detected in the AdvanceTracwith RSC system, and the
AdvanceTracwith RSC button has not been pushed, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced by an authorized dealer immediately.

STEERING
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
•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 the noise is 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 power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort. If the
steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
PREPARING TO DRIVE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.

JUMP STARTING
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets Ford specification WSB-M8B16–A2.
Do not use any special washer fluid such as windshield water repellent
type fluid or bug wash. They may cause squeaking, chatter noise,
streaking and smearing. Refer to theMaintenance product
specifications and capacitiessection in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 40° F (4.5°C),
use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling
system components.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.
