Pressing the control will disable the AdvanceTracwith RSC system and
the traction enhancement feature at and below 20 mph (32 km/h). If the
vehicle is stuck in snow or mud or when driving in deep sand, switching
off the AdvanceTracwith RSC system may be beneficial so the wheels
are allowed to spin. If your vehicle seems to lose engine power while
driving in deep sand or very deep snow and the vehicle speed is 20 mph
(32 km/h) or below, switching off the AdvanceTracwith RSC stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Note:The AdvanceTracwith RSC system will automatically restore to
full functionality every time the vehicle speed exceeds 20 mph (32 km/h)
or the ignition is turned off and back on. However, the AdvanceTrac
with RSC button remains illuminated even above 20 mph (32 km/h) until
it is pressed.
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 or grinding noise
•A slight deceleration of the vehicle
•Steering feedback
•The AdvanceTracwith RSC indicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
All these conditions are normal during AdvanceTracwith RSC
operation.
Do not alter or modify your vehicle’s suspension, steering or
tires; the resulting changes to the vehicle’s handling can
adversely affect the AdvanceTracwith RSC system. Also, do not
install a stereo loudspeaker. The speaker vibrations can adversely
affect the AdvanceTracwith RSC sensors.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. 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. If you experience a severe road event, SLOW DOWN.

Tire change procedure
Preparing to change the tire
To help prevent the vehicle from moving when you change a tire,
be sure the parking brake is set, then block (in both directions)
the wheel that is diagonally opposite (other side and end of the
vehicle) to the tire being changed.
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park).
4. Apply the parking brake and turn
the engine off.
5. Block the wheel that is diagonally
opposite the tire you are changing.
On E-450 vehicles, the parking
brake is on the transmission.
Therefore, the vehicle will not be
prevented from moving when a rear
wheel is lifted, even if the parking brake is applied. Be sure to block both
directions of the wheel that is diagonally opposite to the wheel that is
being lifted.
If the vehicle slips off the jack, you or someone else could be
seriously injured.

1Add the coolant type originally equipped in your vehicle.
2If your vehicle’s rear axle is filled with a synthetic rear axle lubricant it
is considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
