THOR MOTOR COACH | MADE TO FIT
TMC motorhomes may be designed with one or more room
slideouts and/or partial room extensions. Slideouts and
room extensions dramatically increase the usable interior
space of the motorhome when it is parked, creating a more
comfortable living space for you and your fellow travelers.
And when retracted, maintains the motorhome's excellent
road manners.
Before extending the slideout, check around and above
the exterior of the motorhome to be sure the slideout will
not come in contact with anything outside when it is fully
extended. Also check the interior of the motorhome to be
sure that slideout travel is free from obstructions.
For more detailed operating, emergency operating, and
maintenance information, refer to the manufacturer's instruc-
tion manuals available through your on-line TMC Owners
Resource service.
Important procedures for effective slideout
operation:
1. Level the motorhome:
Doing so will keep the slideout square and help to
prevent binding in the slideout opening. Always level
the motorhome before extending slideouts and keep
the motorhome level and stationary until slideouts are
retracted.
2. Provide sufficient power to the slideout motors:
Doing so will aid in proper slideout motor operation.
Slideout motors can draw a signicant amount of current
from the house battery(ies). All TMC motorhomes require
the vehicle’s engine running to operate slideouts (parking
brake must also be set, along with the transmission in Park;
Neutral for Class A Diesels). is provides extra power
to the house batteries via the vehicle’s alternator. If the
slideout system has an ignition lock-out feature, TMC
• For the slideout system to operate (extend or retract),
the motorhome’s engine MUST be running with the
gear selector in PARK and the parking brake must
be ENGAGED.
• For DIESEL PUSHERS ONLY: the engine MUST be
running, while the gear selector is in NEUTRAL and
the parking brake is engaged. These actions ensure
that the slideout has adequate 12-volt power to
operate properly.
NOTICE
You may encounter parking areas where exact leveling
is impossible and getting your motorhome close-to-level
is the best that can be achieved. During these situations,
consider using your motorhome with the Slideouts IN
or NOT extended. The inconvenience of using your
motorhome while a slideout is not extended is better
than risking skewing or damaging a slideout due to an
unleveled motorhome.
NOTICE
The slideout control switch supplied on your motorhome may be
located on the main system panel (illustrated above) or found on the
Slides/Awning menu screen of a multiplex touchscreen panel (below).
