WARNING
Never idle your vehicle for prolonged
periods of time if you sense that ex-
haust fumes are entering the cab. In-
vestigate the cause of the fumes and
correct it as soon as possible. If the
vehicle must be driven under these
conditions, drive only with the windows
open. Failure to repair the source of
the exhaust fumes may result in death,
personal injury, equipment or property
damage.
CAUTION
Do not stay in the vehicle with the en-
gine running or idling for more than 10
minutes with the vehicle's Heater and
A/C ventilation system in RECIRC or
at LOW FAN SPEED. Even with the
ventilation system on, running the en-
gine while parked or stopped for pro-
longed periods of time is not recom-
mended.
NOTE
Keep the engine exhaust system and
the vehicles cab ventilation system
properly maintained. It is recommend-
ed that the vehicles exhaust system
and cab be inspected (1) By a compe-
tent technician every 15,000 miles
(24,140 km) (2) Whenever a change is
noticed in the sound of the exhaust
system (3) Whenever the exhaust sys-
tem, underbody, or cab is damaged.
NOTE
If you are required to idle your vehicle
for long periods of time, install an aux-
iliary heater or automatic idle control.
These auxiliary devices can reduce
fuel consumption and save you mon-
ey.
NOTE
If you are parked next to idling vehi-
cles, move your vehicle or do not stay
in your vehicle for prolonged periods of
time.
