‐
The driver should be aware that
combustible materials could catch
fire from the vehicle's hot exhaust
system.
‐
Carry a fire extinguisher with the
vehicle at these times.
‐
Avoid driving your vehicle through or
over combustible materials such as
leaves, grass vegetation or stubble
high enough to touch, catch or
collect on its hot exhaust system.

Parking or idling should be done
only in an area where there are no
combustible materials under the
vehicle. Failure to follow these
instructions could damage your
vehicle or nearby property.

Firmly apply the parking brake to
prevent the vehicle from moving while
the vehicle height is being changed.

Changing the vehicle height while
driving is very dangerous. As such, the
vehicle will not allow adjustment of
the height while driving

and the parking brake is released, the
vehicle height will return to the
normal position. Pay attention to the
space above the cargo bed.
The vehicle height control system allows for
the decreasing of the vehicle height by
switch operation when loading/unloading
cargo to improve work efficiency.
This system works when the engine control
switch is placed in the "ON" position and
the parking brake is applied.
When the vehicle height is changed, the
system will not operate unless the air
pressure (539 kPa (5.5 kgf/cm²/78 psi)) in the
air tank is secured.
The vehicle height will decrease 6.35 to
8.89 cm (2.5 to 3.5 in).
