BRAKE§
To help with positioning, after backing up to a trailer hitch using Hitch View, Sierra Heavy Duty will automatically apply the parking brake upon shifting into Park to avoid unintentional rolling.
6-SPEED HEAVY-DUTY AUTOMATIC TRANSMISSION
The heavy-duty 6-speed automatic transmission allows the engine to operate in an optimal range at all times with varying load and terrain conditions. This, combined with fortified components used throughout Sierra Heavy Duty’s driveline, provides maximum torque to the wheels at all times.
AVAILABLE TRACTION SELECT WITH TOW/HAUL MODE
The Traction Select System allows you to quickly switch between multiple traction configurations, including Off-Road mode and Tow/Haul mode, to optimize powertrain calibrations, traction control settings and stability control system calibrations for a variety of terrain and driving conditions. The system will retain the tow/haul setting configurations for up to 4 hours after the vehicle is turned off, eliminating the need to re-engage the system when returning from a brief stop or a long journey.
2-SPEED AUTOTRAC TRANSFER CASE
The first heavy duty truck in its class to offer a 2 speed AutoTrac™ transfer case with an active automatic 4WD drive setting provides seamless shifting between two- and four-wheel drive based on road conditions.
EXTERIOR
The available Trailering Mirrors, available MultiPro Tailgate and standard Side Bed Step are just some of the many impressive highlights contributing to the 2023 Sierra Heavy Duty’s powerfully bold exterior.
SIX-FUNCTION GMC MULTIPRO TAILGATE
The available GMC MultiPro Tailgate offers six incredible functions. Standard on SLT and SLE.
INTERIOR
Due to global Semi-Conductor supply shortages, GM vehicles may not have some standard features and options. Please check with your local GMC dealer to confirm the vehicle’s specifications prior to purchase. Vehicles not equipped with Automatic Stop/Start will be less fuel efficient

FORWARD COLLISION ALERT§
Forward Collision Alert can alert you when it detects a front-end collision is imminent with a vehicle ahead of you. The system can also alert you if you are following a detected vehicle much too closely.
LANE DEPARTURE WARNING§
Lane Departure Warning can provide alerts to help you avoid crashes due to unintentionally drifting out of your lane when your turn signal is not activated.
ENHANCED AUTOMATIC EMERGENCY BRAKING§
Automatic Emergency Braking operates below 80 km/h and can alert you when it detects a front-end collision is imminent with a vehicle ahead of you. It also can help reduce the collision’s severity or avoid the collision by automatically applying brakes if you have not already, or by enhancing driver braking.
FRONT AND REAR PARK ASSIST§
Front and Rear Park Assist provides distance alerts to nearby detected objects to help you park and avoid objects at low speeds.
When the unexpected happens, OnStar§ can send the right help even when you can’t ask for it. A trained OnStar Advisor is only a button push away and your GMC can automatically alert us if you’re in a crash. Visit onstararabia.com to know more.
