a. Power-Up Lights
When the ignition key switch is turned to power up the 
vehicle, all lights in the display panel will illuminate for 
three seconds as a test function. During this time, an 
audible alarm will also sound.
The Fasten Seat Belt and Read Manual symbols (Fig. 
10– 46) will remain illuminated for five to seven seconds 
(repeated whenever the seat belt switch senses that 
pressure is removed from the seat), reminding the opera-
tor to fasten the seat belt and to review the 
Owners/Oper-
ators Manual
 if there are any questions about safe and 
proper operation of the vehicle (a manual should be kept 
in the storage compartment beneath the seat at all 
times).
Normal Operating Lights
After the engine starts, the operators display panel (Fig. 
10– 46) provides information via the following indicators:
Figure 10– 46. The operators display panel indicators
illuminate when the vehicle is started.
A. Fuel Level Indicator Bars
Each of the fuel level indicator bars (Fig. 10– 46) repre-
sents approximately 1/4 tank. The vehicle must be 
parked on a firm, level surface to ensure an accurate fuel 
level reading. The fuel level indicator bars will be illumi-
nated with a low-light green hue, easily apparent for night 
visibility and in low-light conditions. When approximately 
1/8 tank is reached, the last fuel level indicator bar will 
stop illuminating, and the fuel level indicator symbol, a 
graphic of a fuel dispensing pump, will change from 
green to orange. When the fuel level indicator symbol 
changes from green to orange, refuel the tank.
B. Travel and Gear Select Indicators
These illuminate to show the direction the travel select 
lever is in (F for FORWARD, N for NEUTRAL, and R for 
REVERSE) and the gear presently engaged.
C. Steering Mode Indicators
The steering mode indicators (Fig. 10– 46) illuminate to 
show which of the steering modes (front-wheel, crab, or 
four-wheel steering) is presently engaged.
D. Attachment Tilt Mode Indicator
One of the two attachment tilt mode indicators will illumi-
nate to show which mode (extend/retract or raise/lower) 
is presently engaged.
Function Indicator Lights
Figure 10– 47. Function indicator lights.
There are three subdued or "hidden" function indicator 
lights (Fig. 10– 47) in the display panel that illuminate only 
when a specific function is activated. They are:
A. Engine Preheat Indicator (Perkins engines only)
This light flashes when the ignition key is held in the 
PREHEAT position (Fig. 10– 48). After 30 seconds, the 
light will glow steadily, indicating the engine is warm 
enough to start.
