3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer to Fuses and relaysin theRoadside
emergencies chapter.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
If your vehicle gets stuck in mud or snow 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: Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the
LOCK position and remove the key whenever you leave your
vehicle.
WARNING: If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized Mazda dealership.
Driving with a 5–speed automatic transmission (if equipped)
Your automatic transmission electronically controls the shift feel by using
an adaptive learning strategy. This feature is designed to increase
durability, and provide consistent shift feel over the life of the vehicle. It
is normal for a new transmission to shift firmly. This operation is
considered normal and will not affect function or durability of the
transmission. Once the vehicle is at operating temperature it may take
several shifts at the same operating condition for the transmission to
properly adapt. Over time the adaptive learning process will fully update
transmission operation. The more varied the driving habits, speed and
torque, the longer it may take to adapt, but the more complete the
process will be.

The rated capacities (as shown in this guide) for trailer towing with the
factory bumper are only valid when the trailer hitch ball is installed
directly into the ball hole in the bumper. Addition of bracketry to either
lower the ball hitch position or extend the ball hitch rearward will
significantly increase the loads on the bumper and its attachments. This
can result in the failure of the bumper or the bumper attachments. Use
of any type of hitch extensions should be considered abuse.
Trailer tow connector
The trailer tow connector is located
under the rear bumper, on the
driver’s side of the vehicle.
Refer to the following chart for information regarding the
factory-equipped trailer tow connector:

the fuse. Check the appropriate
fuses before replacing any electrical
components.
