Vehicle Overview
GMC has launched a new pickup truck called the Canyon for the 2004 model year. Meanwhile, the Sonoma compact pickup, which is a close relative to Chevrolet’s S-10, enters another season but only in four-wheel-drive Crew Cab form. Nothing has changed for the 2004 model year.

A six-CD changer and a ZR5 Appearance Package for Crew Cab pickups became optional during the 2002 model year. A lower-priced version of the SLS Crew Cab, with fewer amenities than its more amply equipped companion, is available.

Crew Cab models have four-wheel drive, a 4.3-liter V-6 engine and four, conventional, front-hinged doors. Only a four-speed-automatic transmission is available, but Sonomas can be fitted with an increased-capacity suspension.

In extended-cab form, Ford’s compact Ranger comes only with two narrow back doors that open toward the rear. Four-door Crew Cab body styles are available on the Dodge Dakota, Nissan Frontier and Toyota Tacoma.

Sonoma Crew Cab pickups ride a 122.9-inch wheelbase and measure 205.3 inches long overall. The cargo bed is just over 4.5 feet long. The Crew Cab’s payload is 1,067 pounds, and the pickup can haul trailers that weigh as much as 5,200 pounds. A bedliner is standard.

GMC’s ZR5 option includes a roof rack and bright aluminum side steps and bed rails. Aluminum wheels hold 15-inch tires on all Sonoma models. Options include a bed extender and either a hard or soft tonneau cover.

Crew Cab pickups have front buckets and a three-place rear bench seat. All Sonomas have air conditioning, a tachometer, a PassLock theft-deterrent system and a stereo system with a CD player. A cassette/CD system is optional. Heated recliner seats with leather trim also are offered. Delayed interior lighting keeps the dome lamp lit for 15 seconds or until the ignition is switched on once the front doors are closed.

Under the Hood
A 4.3-liter V-6 engine is standard in 2004 models, and it produces 190 horsepower and 250 pounds-feet of torque. Only a four-speed-automatic transmission is available.

General Motors’ Insta-Trac four-wheel-drive system is engaged using a switch on the dashboard; an electronic transfer case permits shifting into or out of 4WD-High while moving. A 4WD-Low mode is meant for use on steep grades or muddy terrain.

Four-wheel antilock brakes and daytime running lights are standard. Side-impact airbags are not available.
