DRIVING ON SLIPPERY SURFACES
NOTICE: The engine should never be allowed to exceed the governed
speed. Supplement the exhaust brake with vehicle service brakes
intermittently and/or shift to higher transmission gear to prevent
engine overspeed. A “rule-of thumb” for gear selection is that the
vehicle should be driven down a grade in the same gear that would be
used to climb that grade.
If the system fails to operate or shut off, check the electrical wiring,
wiring connections, and switch adjustment at pedals. Your dealer is
best qualified to adjust and service the exhaust brake system.
NOTICE: When inevitably driving on flooded road, it is advisable to
run slowly at a constant speed while confirming the depth of water.
Otherwise, water may intrude in the engine cylinder and cause
damage on the engine (due to water hammer phenomenon). It is
also advisable to slow down your vehicle and drive with care. After
driving on the flooded road, it is recommended to immediately
bring the vehicle to the Isuzu dealership and let them check
engine, electric parts, transmission, propeller shaft, differential
and transfer for water intrusion, and apply grease and oil to each
area.
Drive, steering and braking traction is reduced when water, snow, ice,
gravel or other material is on the road. Slow down and adjust your
driving to such conditions. It is important to slow down when it is slippery
because stopping distance will be longer and vehicle control more
limited. While driving on a surface with reduced traction, avoid
maneuvers involving sudden steering, acceleration or braking (including
engine braking by shifting to a lower gear), which could cause the tires
to skid. You may not realize the surface is slippery until the vehicle is
skidding. Learn to recognize warning clues—such as enough water or
ice on the road to make a “mirrored surface”—and slow down when
there is any doubt. Also, see “Tire Traction” under “Wheels and Tires” in
Section 5 of this manual.
USE OF THE EXHAUST BRAKE (ON SLIPPERY SURFACES)
The exhaust brake can be used effectively by selecting a higher than
normal transmission gear for the given road speed. The engine will
operate at a reduced rpm; therefore, reducing the retarding effect
when the system is operating.
