CHASSIS
Do not move the vehicle while the leveling jacks
are still in contact with the ground or in the extend
position. This vehicle is equipped with straight-
acting jacks. Moving the vehicle with the leveling
jacks extended can cause severe damage to the
jacks and/or the vehicle and create a driving hazard.
Do not rely solely upon warning lights. It is the
operator’s responsibility to check that all jacks are
fully retracted into the store/travel position and the
vehicle is at the proper ride height for traveling.
WARNING
!
If a red warning light and buzzer come on while
traveling, the jacks should be checked as soon as a
safe parking location is found.
IMPORTANT
!
Manual Hydraulic Operation
Place transmission in the recommended position for
parking the vehicle, and set the parking brake. Turn the
ignition to the “Accessory” position.
Place pads under the jack feet if the ground will not
support the vehicle on the jacks.
Push the “Dump” button. Wait until all air is exhausted
from the vehicle suspension.
The vehicle may be leveled using the manual Extend (up
arrow) buttons on the right half of the panel. If a yellow
Level Sensing light is on, that side, end or corner of the
vehicle is low. It is best to level the vehicle side to side
first, if needed, before front to rear.
When leveling is completed, turn the ignition switch to the
“Off” position.

for more information about the product(s) offered for your coach’s model year.
Jacks will extend (or retract) in pairs to raise (or
lower) a side or end of the vehicle. Any jack not
used for leveling can be extended to the ground.
This provides additional stability against wind and
activity in the vehicle. Jacks used to stabilize the
vehicle after leveling is complete should lift the
vehicle slightly after touching the ground.
NOTICE
!
Do not continue to push an Extend button for more
than ten (10) seconds after that pair of jacks are fully
extended.
IMPORTANT
!
Fluid Level Maintenance
The hydraulic leveling system was filled with Dexron/
Mercon transmission fluid during production. Periodically
check the fluid levels in the leveling system when using
the breather cap/dipstick. Remove any debris from
the dipstick before reinserting it into the reservoir. The
reservoir level should remain between the oil level
grooves when the jacks are retracted. Add fluid as
needed. Change the fluid if it becomes contaminated.
The vehicle can be moved as soon as the red warning
lights are out, the jacks are in the Store/Travel position
and the green “Travel” light is on, if the vehicle is at the
proper ride height for traveling.
Valid Trueline Air Leveling and Electronic Ride
Height System with Touchscreen Operation
This article provides brief operation instructions for a Valid Trueline Leveling System with Electronic Ride Height
Enhancement Touchscreen (Model: VDC00197).
Overview
The leveling and electronic ride height system uses
electronics to control the air suspension for ride control
when traveling, and to control the air suspension for
leveling when stationary.
The stationary leveling features have both an automatic
and manual mode. Auto mode levels the coach with the
touch of a button using the air suspension. Manual mode
allows each corner to be individually raised and lowered
to manually level the coach. Manual mode can be used
with confidence, as the system does not allow the coach
chassis to be twisted beyond allowable limits.
