When entering and exiting your
vehicle, the steps can become very
slippery from mud. Knock mud
off your feet before entering the
vehicle. In wet weather, take extra
care when getting in and out of
the vehicle. Metal steps get slick.
Pay close attention to the rear ramp
area’s lower step. You don’t want to
suffer an injury by having your foot
slip in between the two lower steps!
•±
Allow the engine to warm up to
operating temperature during cold
weather. The diesel engine has to
be warm in order to operate at full
potential.
•±
During wet weather, wipe mud off the vehicle so it doesn’t build up and cover
possible leaks. Also, dried mud is heavy and can damage parts.
•±
Before operating your MaxxPro
®
, make sure the mirror, windshield defroster and
heater work. This will help visibility and raise the chances for mission success.
•±
Ensure that operators are using the correct
mixture of antifreeze to water. Navistar,
the
MAXXPro
®
MRAP
manufacturer,
advises a 50/50 mix. This keeps water in
the cooling system from freezing.
•±
During cold, icy or muddy conditions,
keep vehicle in 4X drive. Otherwise, it
could fishtail or hydroplane.
•±
In cold weather, set the heater flow valve
to the OPEN position. (The valve is located
inside the engine well, on the right side,
next to engine block.)
•±
To avoid engine damage, use the fuel-fired heater in cold weather. You must visually
check for a fuel leak. You want to ensure your vehicle is fully mission capable before
operating it, especially in hostile areas. The fuel-fired heater is on the right side,
behind the condenser, on the frame rail.
•±
In severe weather conditions, place the transfer case in low gear and engage the
front axle for four-wheel drive.
•±
During slippery weather (heavy rain, mud, snow or ice), turn off the engine brake
and do not use it. Using the engine braking system during icy conditions could cause
loss of traction and control.
•±
Driving in mud can make braking harder. If this happens, clean the brakes by driving
about 500 feet with the brakes lightly applied.
•±
SLOW DOWN AND BRAKE SOONER in bad weather. In slippery road conditions or
when there’s less traction, you need to allow for increased stopping distances.
