Engine Exhaust (Carbon Monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is
colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness
and death. If you smell exhaust gas inside your vehicle, keep all windows fully open
and contact an Authorized Mazda Dealer immediately.
Do not run the engine when inside an enclosed area:
Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust
gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss
of consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when
idling the engine:
Exhaust gas is dangerous. When your vehicle is stopped with the windows closed
and the engine running for a long time even in an open area, exhaust gas, which
contains poisonous carbon monoxide, could enter the cabin. Loss of consciousness or
even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe,
before starting the engine:
Running the engine when a vehicle is stopped in deep snow is dangerous. The
exhaust pipe could be blocked by the snow, allowing exhaust gas to enter the cabin.
Because exhaust gas contains poisonous carbon monoxide, it could cause loss of
consciousness or even death to occupants in the cabin.

The three main causes of vehicle-trailer accidents are driver error, excessive speed, and
improper trailer loading.
Before driving
lHave your cooling and braking system checked by an Authorized Mazda Dealer.lBefore starting out, inspect the operation of all vehicle and trailer lights and all vehicle-
to-trailer connections. Stop and re-inspect all lights and connections after driving a short
distance.
Driving
lYour Mazda will handle differently with a trailer in tow, so practice turning, backing,
and stopping in a traffic-free area.
lTake time to get accustomed to the extra weight and length.lAllow more room between your vehicle and the one in front because braking distance
increases with a trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle
and trailer length between your Mazda and the vehicle ahead.
lAvoid jerky starts or sudden acceleration.lAvoid sudden braking. It may cause loss of control and result in jackknifing, especially
so on wet or slippery roads.
lShift the shift lever to the D position when towing a trailer in hilly terrain or when
heavily loaded.
The D position will allow operating the vehicle without frequent shifting.
Lane changes and turning
Avoid quick lane changes, sudden turns, and tight turns. Slow down before turning to
avoid the need of sudden braking.
A turning trailer will make a tighter arc than the tow vehicle. Compensate with turns that
are larger than normal.
Passing
Plan well ahead to pass other vehicles, and provide plenty of room before changing lanes.
Crosswinds from passing vehicles, especially larger ones, and the effects of rough roads
will affect handling.
If swaying occurs, firmly grip the steering wheel and reduce speed immediately, but
gradually.
Steer straight ahead. If no extreme correction of steering or braking is made, the
combination of less speed and firm steering will result in stability.
Backing up
Backing a vehicle with a trailer requires practice and patience. Back slowly, and have a
helper outside at the rear of the trailer to reduce the risk of an accident.
To turn the trailer, place your hand at the bottom of the steering wheel and turn it in the
direction you want the trailer to go. Make only slight movements to prevent sharp or
prolonged turning.

Mode selector dial
Turn the mode selector dial to select
airflow mode (page 6-4).
NOTE
lThe mode selector dial can be set at the
intermediate positions (
) between each
mode. Set the dial to an intermediate
position if you want to slightly adjust the
airflow amount.
lFor example, when the mode selector dial is
at the
position between theand
positions, airflow from the floor vent is less
than that of the
position.
A/C switch
Press the A/C switch to turn the air
conditioner on. The indicator light on the
switch will illuminate when the fan
control dial is set at position 1, 2, 3, or 4.Press the switch once again to turn the air
conditioner off.
NOTE
The air conditioner may not function when the
outside temperature approaches 0 °C (32 °F).
Air intake selector
This switch controls the source of air
entering the vehicle.
Press the
switch to alternate
between the outside air and recirculated
air modes.
It is recommended that under normal
conditions the switch be kept in the
outside air mode.
Outside air mode (indicator light
turned off)
Outside air is taken into the vehicle. Use
this mode for normal ventilation and
heating.
Recirculated air mode (indicator light
illuminated)
Outside air is shut off. Air within the
vehicle is recirculated.
This mode can be used when driving on a
dusty road or in similar conditions. It also
helps to provide quicker cooling of the
interior.

maintain maximum comfort.
lThe air to the floor is warmer than air to
the face (except when the temperature
control dial is set at the extreme hot or cold
position).
lIn theorposition, the air
conditioner is automatically turned on
(however, the indicator light does not
illuminate) and the outside air mode is
automatically selected to defrost the
windshield.
In the
orposition, the outside air
mode cannot be changed to the recirculated

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
WARNING
Switch the ignition to off and
make sure the fan is not running before
attempting to work near the cooling
fan:
Working near the cooling fan when it
is running is dangerous. The fan
could continue running indefinitely
even if the engine has stopped and
the engine compartment temperature
is high. You could be hit by the fan
and seriously injured.
Do not remove either cooling
system caps when the engine and
radiator are hot:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the temperature gauge indicates
overheating:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P).3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the
engine temperature will increase.
Stop the engine and call an
Authorized Mazda Dealer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant reservoir
level.
If it's low, look for coolant leaks from
the radiator and hoses.

If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
8-23).
CAUTION
If the engine continues to overheat or
frequently overheats, have the
cooling system inspected. The engine
could be seriously damaged unless
repairs are made. Consult an
Authorized Mazda Dealer.
