Subaru IMPREZA 2011 Service Manual – OEM Factory Specifications

If you are pulling a wrench on a 2011 Subaru IMPREZA without the factory Service Manual, you are working blind. I have seen good techs ruin a head gasket because they used an aftermarket torque chart that was off by 15 ft-lbs. This book is 2752 pages of what Fuji Heavy Industries wrote for their own dealers. Every specification in the SPECIFICATIONS SPC section – dimension, engine, electrical, transmission, steering, suspension, brake, tire, capacity, weight – came off the assembly line. Not from some third-party reprint that took a guess.

This manual is a direct PDF scan of the OEM binder. The PRECAUTION PC section alone should scare you into using it. It lists 16 separate caution areas, including ABS brake fluid, radiator fan, airbag disposal, and the exact procedure for removing hoses so you don’t snap a clip. Aftermarket manuals condense that into two paragraphs. Subaru gives you eight pages.

SPECIFICATIONS SPC: Dimensions, Engine, and Capacities

The SPECIFICATIONS SPC chapter runs through everything you need before you order parts. Engine displacement, compression ratio, electrical load ratings, transmission gear ratios, steering rack travel, suspension bushing torque, brake rotor minimum thickness, tire pressure, and fluid capacities. The capacity table lists oil, coolant, ATF, and differential fluid volumes in quarts and liters. If you are doing a fluid flush on a 2011 Impreza, you get the factory fill numbers – not the “enough to cover the dipstick” method.

What Does the Pre-Delivery Inspection Cover?

The PRE-DELIVERY INSPECTION PI section is a 38-item checklist that Subaru uses before the car leaves the lot. It includes torque spec checks on the front hood latch, child safety lock function, TPMS sensor registration (U.S. models), and even the delivery test mode connector. If you are diagnosing a no-start or a warning light after a repair, go back to this section. The IMMOBILIZER SYSTEM and ECM PROTECTOR steps are there. I had a guy spend three hours chasing a crank-no-start because he skipped the immobilizer relearn. Page 73? Data needed, but the procedure is inside.

3 Critical Safety Sections You Cannot Skip

The HOW TO USE THIS MANUALS HU chapter defines the structure and the definitions of “NOTE”, “CAUTION”, and “WARNING”. That sounds basic until you realize the PRECAUTION PC section tells you exactly how to disable the airbag module and the special tool required. The NOTE NT section covers jack-up points, tie-down ranges, and towing directions – all with diagrams. If you use a two-post lift on a 2011 Impreza without checking the lifting points in this manual, you risk crushing the rocker panel or pulling the rear subframe out of alignment.

Use the Precaution Section Before You Touch Anything

Open the PRECAUTION PC chapter. It lists VEHICLE DYNAMICS CONTROL (VDC) cautions, brake fluid handling, radiator fan warnings, and a full breakdown of airbag disposal procedures. The manual says: “Before the removal and installation operation of hoses, etc.” – followed by a checklist. That level of detail keeps you from getting a face full of fuel or coolant. If you are working on a car that has been in a minor front-end hit, the WINDOW ADHESIVE and FRONT HOOD DAMPER STAY notes save you from breaking expensive glass.

Pre-Delivery Inspection: What the Factory Requires

The PI section is not just for dealerships. If you are buying a used 2011 Impreza, use this checklist to verify every system. It includes tire pressure, fuse installation, door lock/ unlock, trunk lid release, fuel lid lock, keyless entry, security system, seat belt operation, and the navigation system clock. Each step has a pass/fail and a note on what to torque or adjust. The manual does not assume you know how to set the clock – it tells you.

Also refer to Automotive Industry Overview for industry standards on repair documentation.

Is this a reprint or a scan of the actual OEM manual?

It is a digital scan of the genuine Subaru Service Manual. The original file name is SUBARU_IMPREZA_2011_Service_Manual_en-44109007311.pdf. 2752 pages, color diagrams, and real torque tables.

Does this manual cover the CVT transmission?

Yes. The TRANSMISSION section under SPECIFICATIONS SPC includes both manual and automatic transmission data, and the periodic maintenance services section covers CVT fluid change intervals and procedures.

What year is this manual for?

2011.

Where are the wiring diagrams located?

Wiring diagrams are in the electrical section of the body manual. This service manual includes diagnostic procedures and connector views, but for full wiring schematics, you need the separate wiring diagram manual. However, this manual covers all electrical component testing, including the ECM, ABS module, and VDC control unit.

You can waste your time hunting for specs on forums or buy a reprint that got the torque wrong. Or you can access the factory manual and know that every number came from Subaru. Make the call that keeps your work straight. Access the Factory Manual.
