Terrain Assist
These are Low Speed, Crawl, Grade and Terrain Assist Indicator symbols. The symbols have a similar look, depicting and SUV-like vehicle on surfaces of various angles and composition. A given symbol will be active only when the system is activated, so if its a surprise, look for an off switch. It will likely have the same symbol on it. Makers of 4-wheel drive vehicles have developed systems to help drivers in off-road environments such as rugged or slippery terrain or steep grades.
- But first, is one of these truly your symbol?? If yes, continue on below.
- Otherwise return to our main Picture Symbols page and scan again!
One manufacturer offers this indicator with the set of bars and the word CRAWL above it. It indicates that simply that Crawl Control is turned on. Then the system mode can be chosen: Lo, Lo-Mid, Mid, Mid-Hi and Hi. The range moves from essentially rough roads to very gravelly or snow covered roads.
Many More Versions
Grade assist applies a continuous balance of braking and throttle adjustments to avoid slipping or getting stuck on difficult or slick terrain. Thus the speedometer shown in one image. The system is similar to the Start Assist shown next. The yellow amber version is an All Terrain Progress Control (ATPC) indicator. It is shown to confirm that the ATPC system is enabled. The color is chosen by the manufacturer.
One manufacturer sees this as Selec-Speed Control (SSC) and is intended for off-road driving in 4WD Low only. As with the other systems, SSC maintains vehicle speed by actively controlling engine torque and brakes. It is activated by pushing the SSC switch.
In this case, the color is black and white, as the indicator is displayed on the vehicle’s information screen. the acronym DSR stands for Downhill Speed Regulation. The appearance of the symbol indicates a problem with the system, which will be spelled out in text on the screen.
The symbol to the left is a Hill Start Assist (HSA) Off Indicator symbol, which will be on if there are any malfunctions while the engine is running indicating that the system is deactivated.
To the right are Hill Holder Indicator symbols, which will be illuminated when the hill holder switch is activated. Since the system makes use of the vehicle’s brakes, a brake problem is indicated if the light does not come on when the switch is activated. If this occurs, contact you dealer or authorized service center as soon as possible.
These versions indicates a problem with the Hill Start Assist system. This is why they is seen in yellow/amber/orange. If it is seen, your dealer or a qualified service shop will be needed. The symbol is shown as a car on an angled line alone or inside a circle which itself is inside brackets. The circle and brackets are commonly used in symbols that involve the the vehicle’s brake system.
