On Rough Roads And In Bad Weather - Mitsubishi 2010 Fuso FE Owner's Manual

NOTE:
"Overrev" refers to an operating state of the engine
in which it rotates at an RPM higher than the recom-
mended maximum RPM. Overrevving the engine
could lead to an engine failure.

On rough roads and in bad weather

•
Use a low gear and try to drive at a constant
speed when driving on gravel roads or muddy
roads.
•
Do not race the engine when attempting to
move out of mud. Racing the engine is useless
and even worsens the condition as the spinning
wheels will make ruts deeper. Instead, place
thick waste cloth, gravel or the like under tires,
and engage the 1st and reverse gears alter-
nately or, in an automatic transmission vehicle,
shift the range selector lever into the "D" and "R"
positions alternately to move the vehicle back
and forth until you can drive out.
CAUTION
Do not operate an automatic transmission in
this way for more than 5 minutes since it causes
the transmission oil to heat up rapidly.
•
Drive very slowly on bumpy roads and take care
not to allow the undercarriage to bottom out.
When the diesel particulate filter (DPF) strikes a
rock or other obstacle, its internal catalyst and
ceramic filter may be damaged. Have it checked
by an authorized dealer.
•
Avoid sudden steering and sudden braking on
roads which are slippery from rain. Conditions
are especially dangerous just after it begins to
rain. Use engine braking and the exhaust brake
together with the wheel brakes to decelerate.
Note, however, that sudden engine braking can
cause a skid. Drive at a speed at which you can
stay comfortably in control of the vehicle.
•
When the vehicle is driven through puddles or
washed with water, braking performance can be
reduced by water entering the brake drums or
splashed over the brake discs. In this event,
drive slowly with light pressure on the brake
pedal to dry out the brakes. Pay attention to
nearby vehicles while doing so.
