Some Dodge Nitro sport-utility vehicles are equipped with four-wheel drive. When 4WD is engaged, power is supplied to all four wheels through the transfer case. Using 4WD aids in driving on sand, snow, mud and rough roads. It makes travelling possible when weather conditions have made roads impassable for two-wheel-drive vehicles. Switching from two- to four-wheel drive on a Dodge Nitro can be accomplished by changing the vehicle's settings.
Insert the ignition key and move it to the "ACC" position.
Rotate the transfer case switch to the "4WD Lock" position while the Dodge Nitro is stationary. The switch is on the centre console. The front and rear driveshafts will be locked together and when moving, the Nitro's front and rear wheels will rotate at the same speed.
Start and drive the vehicle. Only use this setting when you're about to drive on loose, slippery surfaces.
Monitor the "4WD" indicator light on the dash for flashing. If it's not flashing, the wheels are not spinning due to loss of traction, and you can proceed to the next step. If it is flashing, reduce speed until the wheels stop spinning through lack of traction.
Rotate the transfer case switch to the "4WD Lock" position while the Dodge Nitro is moving, but not spinning its wheels.
Release the accelerator pedal for a moment after turning the switch to engage 4WD more quickly.
Uneven tire wear, low tire pressure and overloading can increase the time it takes to shift back to two-wheel drive.
