Driving on Uneven Road
▼Driving on Uneven Road
Your vehicle's suspension and
underbody can be damaged if driven
on rough/uneven roads or over speed
bumps at excessive speeds. Use care
and reduce speed when traveling on
rough/uneven roads or over speed
bumps.

Use care not to damage the vehicle's
underbody, bumpers or
muffler(s)
when driving under the following
conditions:
Ascending or descending a slope
with a sharp transition angle
Ascending or descending a driveway
or trailer ramp with a sharp transition
angle

This vehicle is equipped with low
pro file tires allowing class-leading
performance and handling. As a result,
the sidewall of the tires are very thin
and the tires and wheels can be
damaged if driven through potholes or
on rough/uneven roads at excessive
speeds. Use care and reduce speed
when traveling on rough/uneven roads
or through potholes.

(SKYACTIV
-G 2.5T)
CAUTION

After driving at freeway speeds or up
a long hill, idle the engine at least 30
seconds before stopping it.
Otherwise, the turbocharger could
be damaged.
 Racing or over-revving the engine,
particularly after it's just been
started, can damage the
turbocharger.
 To protect the engine from damage,
the engine is designed so that it
cannot be raced just after starting it
in extremely cold weather.
The turbocharger greatly enhances
engine power. Its advanced design
provides improved operation and
requires minimum maintenance.

To get the most from it, observe the
following.
1. Change engine oil and filter
according to Scheduled
Maintenance.
Refer to Scheduled Maintenance
(U.S.A. and Puerto Rico) on page
6-4.
Refer to Scheduled Maintenance
(Canada) on page 6-6.

Introduction
▼Introduction
Be careful not to hurt yourself when
inspecting your vehicle, replacing a
tire, or doing some kind of
maintenance such as changing the oil
and
filter. In particular, wear thick work
gloves such as cotton gloves when
touching areas that are difficult to see
while inspecting or working on your
vehicle. Doing inspections or
procedures with your bare hands could
cause injury.

If you are unsure about any procedure
this manual describes, we strongly urge
you to have a reliable and qualified
service shop perform the work,
preferably an Authorized Mazda
Dealer.

Factory-trained Mazda technicians and
genuine Mazda parts are best for your
vehicle. Without this expertise and the
parts that have been designed and
made especially for your Mazda,
inadequate, incomplete, and
insu fficient servicing may result in
problems. This could lead to vehicle
damage or an accident and injuries.

For expert advice and quality service,
consult an Authorized Mazda Dealer.

To continue warranty eligibility and to
protect your investment, it is your
responsibility to properly maintain your
vehicle according to factory
recommended schedules outlined in
this manual. As part of this you must
keep your maintenance records,
receipts, repair orders and any other
documents as evidence this
maintenance was performed. You must
present these documents, should any
warranty coverage disagreement occur.
Failure to do so can result in your
warranty being voided either in whole
or in part.

This evidence may consist of the
following:
The Mazda Scheduled Maintenance
Record, refer to the Warranty
Booklet, must be completely filled
out showing mileage, repair order
number, date for each service, and
signed by a qualified automotive
service technician who service
vehicles.
Original copies of repair orders or
other receipts that include the
mileage and date the vehicle was
serviced. Each receipt should be
signed by a qualified automotive
service technician.
For self maintenance, a statement
that you completed the maintenance
yourself, displaying mileage and the
date the work was performed. Also,
receipts for the replacement parts ( fl uid, filters, etc.) indicating the date
and mileage must accompany this
statement.
