air suspension FORD TRANSIT 2021 Owners Manual

Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty and durable load
carrying capability. For this reason, we
strongly recommend that you do not make
modifications such as adding or removing
parts (such as lowering kits or stabilizer
bars) or by using replacement parts not
equivalent to the original factory
equipment.
Any modifications to a vehicle that raise
the center of gravity can make it more likely
the vehicle will rollover as a result of a loss
of control. We strongly recommend that
caution be used with any vehicle equipped
with a high load or device (such as ladder
or luggage racks).
Failure to maintain your vehicle properly
could void the warranty, increase your
repair cost, reduce vehicle performance
and operational capabilities and adversely
affect driver and passenger safety.
Frequent inspection of vehicle chassis
components is recommended if the vehicle
is subjected to off-highway usage.

WARNING: Do not spin the
wheels at over 34 mph
(55 km/h). The tires may fail and
injure a passenger or bystander.
Driving habits have a great deal to
do with your tire mileage and
safety:
• Observe posted speed limits.
• Avoid fast starts, stops and
turns.
• Avoid potholes and objects on
the road.
• Do not run over curbs or hit the
tire against a curb when
parking.
Highway Hazards
No matter how carefully you drive
there is always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
If you feel a sudden vibration or
ride disturbance while driving, or
you suspect a tire or your vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove wheel and replace it with the spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
the tires. If your vehicle seems to
pull to one side when you are
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of the tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension may
require alignment of all four
wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.
