4 Wheel Drive Indicators

4 Wheel Drive

These are 4 Wheel Drive Low Indicator symbols. They indicates that the 4 wheel drive is engaged at a low gear ratio. This ratio is useful when maximum power or traction is needed for steep climbs, sandy or muddy conditions, or off-road driving. Four wheel drive is often shown as 4×4 in publication and may be used in the symbol. LOW may be spelled out or abbreviated.

These two are corresponding 4 Wheel Drive High indicators. The High setting is the default setting in a 4 wheel drive vehicle for normal driving conditions. For this reason, vehicle manufacturers rarely add this indicator. If it is added, High may be spelled out or abbreviated (HI). One manufacturer simply uses a 4×4 Indicator to mean that the vehicle is in 4×4 HIGH.

This indicator, 4WD AUTO, states that the vehicle is in AUTO mode. The vehicle will automatically engage 4 wheel drive when a loss of traction is sensed.  Otherwise, the front axle is engaged, but the vehicle’s power is sent only to the rear wheels.

These symbols, a 4×2 or 2H Indicator, say that a 4 wheel drive vehicle is supplying power only to the rear wheels. The use of the rear wheels only is the correct choice in typical driving conditions. That is, smooth, dry roads.

The 4A, 4×4 Auto Indicators and the stick figure indicator with 4WD text in the center both say that 4-wheel drive will be available automatically for additional traction. Only electronically-controlled 4-wheel drive systems will have this available. These indicators become 4 wheel drive trouble lights if they remain on when the system is not engaged.

This symbol with the open circles is used in Australia and New Zealand to indicate only that the 4-wheel Drive system has been engaged. In North America, the same symbol is usually used to indicate a problem with an All-wheel Drive system, although Chevrolet has begun using it to also indicate the system is engaged.

General Motors uses an indicator for five possible choices. Their system can be set to AUTO (automatic (AUTO), 4 high (HI), 4 LOW, 2 wheel drive (2WD) and finally N (or NEUTRAL in yellow/amber), seen below, if it is left in neutral. This final setting is useful as a warning if it has been left in neutral accidently. It indicates that nothing is engaged. The vehicle could roll away and won’t move if placed into gear!

In all cases, the various 4-wheel drive systems are choices that can be made by the driver using either a lever or buttons. If the system will allow a different selection, or if a 4×2 indicator remains illuminated, contact your dealer or authorized service center immediately. Driving will be possible, but only at reduced speed.
