Air Filter Indicator
The air filter indicator is behind the grille at
the front of the cab. If the indicator is in the
red area (showing the text "service"), the
air filter is seriously fouled and must be
replaced. Consult an authorized Service
dealer. Clogged air filters lead to increased
fuel consumption and loss of power.
Wheels and Tires
1. Remove any stones, etc. from the
tread and from between the tires (if
twin wheels are fitted).
2. Check for evidence of wear and
damage and for nails or other foreign
objects caught in the tires.
3. Check the attachment of the wheels.
4. Check the tire pressures (do not forget
the spare wheel). The tire pressures
should be checked and corrected
while the tires are cold. See Tire
Pressure Table (Imperial) on page 113
or Tire Pressure Table (Metric) on
page 114 for the correct tire
pressures.
NOTE
If a worn tire is underinflated by 30 psi,
the ABS control will be inoperative un-
der extreme conditions!
Lighting and Instruments
1. Check the vehicle lighting, brake lights
and instruments for correct operation.
2. Also check the operation of the horn,
windshield wipers and washers.
Driver's Seat and Mirrors
Set the seat and mirrors to the correct
positions.
Mirrors with field of vision projected on the
ground.
