Your car’s exhaust contains carbon
monoxide gas. You should have no
problem with carbon monoxide
entering the car in normal driving if
you maintain your car properly.
Have the exhaust system inspected
f or leaks whenever:The car is raised f or an oil change.
You notice a change in the sound
of the exhaust.

may have damaged the underside. High levels of carbon monoxide can collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
car out of the garage. With the trunk lid open, air f low can
pull exhaust gas into your vehicle’s
interior and create a hazardous
condition. If you must drive with the
trunk lid open, open all the windows
and set the heating and cooling
system as shown below.
If you must sit in your parked car,
even in an unconf ined area, with the
engine running, adjust the heating
and cooling system as f ollows:
Push the button.
Select the mode.
Turn the f an on high speed.
Set the temperature control to a
comfortable setting.

Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill
you.
Avoid any enclosed areas or
activities that expose you to
carbon monoxide.

The tachometer shows the engine
speed in revolutions per minute
(rpm). To protect the engine f rom
damage, never drive with the
tachometerreadingintheredzone.
This shows the temperature of the
engine’s coolant. During normal
operation, the reading should be in
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may reach near
the red mark. If it reaches the red
mark, pull saf ely to the side of the
road. Turn to page for
instructions and precautions on
checking the engine’s cooling
system.
The Select button switches the
