Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
When braking, apply the brakes as you normally would. In order to allow
the anti-lock brake system (ABS) to operate properly, keep steady
pressure on the brake pedal.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

HAZARD FLASHER
The hazard flasher is located on the
steering column, just behind the
steering wheel. The hazard flashers
will operate when the ignition is in
any position or if the key is not in
the ignition.
Push in the flasher control and all
front and rear direction signals will
flash. Press the flasher control again
to turn them off. Use it when your
vehicle is disabled and is creating a
safety hazard for other motorists.
Note:With extended use, the flasher may run down your battery.
FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.

CHANGING THE TIRES
If you get a flat tire while driving:
• do not brake heavily.
• gradually decrease the vehicle’s speed.
• hold the steering wheel firmly.
• slowly move to a safe place on the side of the road.
Note: The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.

1. Park on a level surface, activatehazard flashers and place
gearshift lever in P (Park)
(automatic transmission) or 1
(First) (manual transmission).
2. Set the parking brake and turn engine OFF.
3. Block the diagonally opposite wheel.
4. Insert tapered end of the lug wrench behind hub caps and
twist them off.
5. Loosen each wheel lug nut one-half turn counterclockwise
but do not remove them until
the wheel is raised off the
ground.
6. Position the jack according to the following guides and turn
the jack handle clockwise until the tire is a maximum of 1 inch (25
mm) off the ground.
WARNING: To lessen the risk of personal injury, do not put any
part of your body under the vehicle while changing a tire. Do
not start the engine when your vehicle is on the jack. The jack
is only meant for changing the tire.
WARNING: Do not let anyone stay in the vehicle when you are
using the jack; have them stand in a safe place out of traffic
lanes.

WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque at 50–100 miles (80–160
km) after any wheel disturbance (rotation, flat tire, wheel removal, etc.).
Lug nut socketsize/Bolt size Wheel lug nut torque*
lb.ft. N•m
Lug nut socket size:
34” (19 mm) hex
Bolt size:12x 20 100
135
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Mazda recommended replacement fasteners. WARNING: When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake
drum or brake disc that contacts the wheel. Ensure that any
fasteners that attach the rotor to the hub are secured so they
do not interfere with the mounting surfaces of the wheel.
Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen
and the wheel to come off while the vehicle is in motion,
resulting in loss of control.
Note: If there is corrosion on the area where the wheel contacts the
hub, apply a thin film of grease or anti-seize compound on that area.
OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
