HEATING AND AIR CONDITIONING
A large capacity, central A/C provides enough
conditioned and filtered air for all climatic
conditions. Fresh air is drawn into the system
from the evaporator compartment on driver’s
side of the vehicle. Return air is taken from the
middle of the vehicle. The driver’s heater and
defogger are controlled separately from the
central unit. An air mixture selector enables air
to be drawn into the system from outside the
vehicle or recirculated. Optionally, condensers
installed in the overhead storage compartments
provide cool air to the seated passengers from
the overhead registers.

OIL SPECIFICATIONS
ENGINE
For the Volvo D13M engine, we recommend
using SAE 10W30 ‘’Volvo Premium Motor Oil
VDS-4.5’’ or other Volvo Approved VDS-4.5 oils.
Volvo VDS-4.5 oils exceed API service category
Ck-4 oils.
ALLISON TRANSMISSION
The Allison transmission must be filled with
Castrol TranSynd™ or TES 295 fluid or TES 389
fluid.
VOLVO I-SHIFT TRANSMISSION
Only use VOLVO-approved synthetic
transmission oil in the I-Shift transmission.
Refer to section 24 of the Maintenance Manual
for more information about oils approved by
Volvo.
DIFFERENTIAL
Multigrade gear oil meeting MIL-PRF-2105E:
85W140 is recommended for use in drive axle.
This lubricant performs well over a broad
temperature range, providing good gear and
bearing protection in a variety of climates. If
temperature drops below 10°F (-12°C), 80W90
should be used, and below -15°F (-26°C), 75W90
should be used. In extreme conditions or for
better performance, full synthetic gear oil
should be used.
POWER STEERING RESERVOIR
Use Automatic Transmission Fluid (ATF) Dexron-
IIE or Dexron-III for this system.
