3. On automatic transmission vehicles, try to start the
engine in each gear. The starter should work only
in P (Park) or N (Neutral). If the starter works in
any other position, your vehicle needs service. On
manual transmission vehicles, the starter should
work only when the clutch pedal is all the
way down.
Transmission Shift Indicator Check
Check that the indicator points to the gear chosen.
Steering Check
Be alert for any changes in steering action, abnormal
front tire wear, or steering wheel position. An inspection
or service is needed when the steering wheel is harder
to turn or has too much free play, or if there are strange
sounds when turning or parking.
Brake System Check
Be alert to the low air warning light or tone alarm,
or changes in braking action, such as repeated pulling
to one side, unusual sounds when braking, or increased
brake pedal travel. Make sure air brake system
reservoirs are drained daily with full system air
pressure, and check system for leaks. Any of these
conditions could indicate the need for brake system
inspection and/or service.
Engine Cooling System Service
Inspect the hoses and have them replaced if they are
cracked, swollen, or deteriorated. Inspect all pipes,
fittings, and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of the
cooling system and pressure cap is recommended at
least once a year.
Exhaust System Inspection
Be alert for any changes in the sound of the exhaust
system or any smell of fumes. These are signs the
system may be leaking. Have it checked and/or
repaired at once. See
Engine Exhaust on page 2 ‑ 27
and Running the Vehicle While Parked on page 2 ‑ 32 .
Check to be sure that mud or dirt is not caked on the
exhaust system, especially in the area of the diesel
particulate filter and tailpipe. Clean the area as needed.
See
Diesel Particulate Filter on page 2 ‑ 28 .
At high mileages, the DPF becomes loaded with ash.
This is normal. When the amount of ash loading is high,
see your dealer/retailer for DPF cleaning or
replacement.
