Turbocharger Information
CAUTION
After driving at freeway speeds or up a long hill, trailer towing for a long time, idle the
engine at least 30 seconds before stoppi ng 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 accordi ng to Scheduled Maintenance (page 6-4).
2. Use only recommended engine oil (page 6-20). Extra additives are NOT recommended.

Introduction
Be careful not to hurt yourself when inspecting your vehicle, replacing a tire, or doing some
kind of maintenance such as car washing. 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 insufficient 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 orde rs 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 (fluid, filters, etc.) indicat ing the date and mileage must accompany this
statement.
