The Chevy Trailblazer hit the automobile market in 2002 and proved in many reviews to be a very durable and powerful vehicle. The Trailblazer, which is powered by a straight six-cylinder engine is capable of generating over 275 horsepower, and is available in both 2- and 4-wheel drive. The 4-wheel drive capability of the Trailblazer is simple to use due to a rotary knob and the vehicle automatically changes gears when slippage is detected. It is best to use a Trailblazer in 4-wheel drive mode on rugged terrain, unpaved roads, or on inclines. 4-Wheel drive is not recommended for normal road travel or everyday use.
Locate the rotary knob marked 4-WD, or 4, depending on what year your Trailblazer was manufactured in. Depending on the year, this knob will either be located on the center dashboard or near the Automatic gear shift.
Turn the knob clockwise to engage the 4-wheel drive. The knob has a ring around it that will light up when it is engaged.
Drive slowly over uneven or bumpy dirt roads. Despite its 4-wheel drive capability, the Trailblazer has relatively low ground clearance and can easily rub hard on rocky terrain. Slowly ascend inclines as well. Fast ascents on inclines can put great strain on the transmission and may ruin the vehicle if it is pushed too hard for too long.
