Driving off-road with 4WD
Your vehicle is specially equipped for driving on sand, snow, mud and
rough terrain and has operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. For more
information on driving off-road, read the“Four Wheeling”supplement in
your owner’s portfolio.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.

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.
4. 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, then turn the ignition switch
to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
•If neither coolant nor steam is escaping:open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.

5. Check the coolant level. If it is low, look for leaks in the radiator
hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an Authorized Mazda dealer.
SeeAdding coolantin theMaintenance and specificationssection. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note:If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
JUMP STARTING YOUR VEHICLE
WARNING: The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING: Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; doing so may
damage the catalytic converter.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.

Severe climates
If you drive in extremely cold climates (less than–34°F[–36°C ]):
•It may be necessary to increase the coolant concentration
above 50%.
•NEVER increase the coolant concentration above 60%.
•Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
freeze protection at the temperatures in which you drive in the
winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about Limp to Safety cooling (2.3L I4
engine only)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily to a place of safety. The distance it can be driven
depends on ambient temperatures, vehicle load and terrain, so when the
engine drops into this mode, it is because the engine has overheated and
you need to take special care to avoid it shutting down.

How Limp to Safety works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
symbol will illuminate.
•TheCheck engineindicator light
will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
This system has given you an early warning of engine damage and you
should immediately drive to a place of safety where the engine can be
cooled or the vehicle towed to a service shop. Continuing to drive in this
Limp to Safety mode will increase engine temperature some more,
increasing the chance of engine damage, and:
•The engine will completely shut down.
•Steering and braking effort will increase.
If you have decided not to have the vehicle towed, and when the engine
temperature cools, you try to re-start it and it appears to have returned
to normal operation, don’t delay in getting to a service facility as soon as
possible to diagnose what caused the overheat and prevent further
engine damage.
When Limp to Safety mode is activated
You have limited engine power when in the Limp to Safety mode, so
drive the vehicle with caution. The vehicle will not be able to maintain
high speed operation and the engine will run rough. Remember that the
engine is capable of completely shutting down automatically to prevent
engine damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait for the engine to cool down.
4. When the engine has cooled down, first check the coolant level. If
low, then use a rag and carefully turn the cap one notch
