2014 GMC sierr a. To engineer our most dynamic and advanced pickup ever, we didn’t limit ourselves to the usual truck innovations. For the all-new 2014 Sierra, we ventured far beyond the automotive category to discover some incredible technologies. For our new available Safety Alert Driver Seat, we’re utilizing haptic sensory feedback to alert drivers through their sense of touch. Twenty-first century, smart-grid power generation that conserves energy when demand is low, then makes more when it’s needed, was the inspiration for our new EcoTec3 engines that offer abundant power and efficiency.1 And why should fighter pilots be the only ones to benefit from touch-screen technology? In Sierra, they aren’t. Discover how these and other innovations make the 2014 Sierra more than just a truck. It’s incredible thinking in the form of a truck. That’s Professional Grade. EPA-estimated 16 city/23 hwy mpg (2WD), 16 city/22 hwy mpg (4WD) with the optional 5.3L V-8 engine.
2014 Silverado and Sierra Score a Safety First for Trucks New Chevrolet, GMC crew cabs receive first five-star scores under new rating system DETROIT – The 2014 Chevrolet Silverado 1500 and High Country and the GMC Sierra and Sierra Denali 1500 are the first pickup trucks to receive the highest possible five-star Overall Vehicle Score for safety since the National Highway Traffic Safety Administration changed its New Car Assessment Program for the 2011 model year. NHTSA only tested the crew cab models of Silverado and Sierra. Chevrolet and GMC expect crew cab models to account for 60 percent of their 2014 light duty full-size pickup truck sales. “Safety is as important to truck buyers as it is to car buyers,” said Gay Kent, GM general director of Vehicle Safety and Crashworthiness. “Silverado and Sierra set a benchmark for pickup truck safety by offering a full array of advanced features designed to protect occupants before, during and after a collision.” Silverado and Sierra offer fully boxed frames, extensive use of high-strength steel, and several segment-exclusive safety features are available, including Forward Collision Alert, Lane Departure Warning, and Safety Alert Seat. Safety Alert Seat warns the driver of potential traffic danger using directional vibration pulses from the seat cushion. The patented warning approach is tied to all of the onboard crash avoidance systems.

EMERGENCY POWER KIT FOR CHEVROLET VOLT FEATURES: Utilizes 12V accessory power system of the Volt Provides backup power without needing to run the Volt’s gasoline engine* Includes all hardware and accessories designed specifically for the Volt No drilling or other modifications to the Volt are needed Quick disconnect system allows for easy connection of inverter Maximum Inverter Size supported: 1000W with 2000W surge. Installation Time: 30 minutes DESCRIPTION: The EVEX-1000W is a do-it-yourself** wiring kit to provide emergency backup power from your Chevrolet Volt. The kit is custom-designed for the Volt, to allow for a hidden installation with power connector access through the fuse box compartment on the left-side of the hatch storage area. The kit includes a fuse holder with fuse, heavy duty wires cut to length with soldered leads and pre-installed wire terminals, as well as a heavy duty connector set to allow quick connections to the inverter of your choice as needed. The kit is designed for a maximum inverter size of 1000W with 2000W surge. This maximum size is designed to work within the limits of the Volt’s 12V power electronics design. WHAT’S INCLUDED: Fuse holder and fuse, with heavy duty Velcro to secure holder 4AWG wiring for positive and negative 12V connections 8AWG wiring for chassis connection (required by some inverters) High current DC connector for quick inverter connect when emergency power is needed Step by step instruction manual for installation 1000W true sine wave inverter (optional, select when ordering) More details including frequently asked questions are available on our website. * The vehicle is required to be turned on for emergency back-up power. In most scenarios, the engine will not run, and the 12V system will get its power from the Volt’s high voltage traction battery. In some scenarios however, the engine may cycle on and off intermittently. This may occur if the high voltage traction battery is depleted, if the vehicle is in mountain or hold mode, if temperatures are below 40F, or if the vehicle’s hood is open. Always make sure vehicle is in a properly ventilated area! Exhaust will be emitted when engine is running. ** If you are not experienced and comfortable with 12V wiring, please seek the assistance of a professional.
