  • Clean headlights and tail lights and check them for signs of damage.
  • Clean the front and rear number plates.
  • Clean the tire tread with a jet of water and remove any foreign objects.
  • Clean wheels, wheel housings and the underbody with a jet of water.
  • Check whether the vehicle has picked up plant parts or branches.
    These materials increase the risk of fire and can damage fuel lines, brake hoses, boots of the axle joints and drive shafts.
  • After off-road driving, always check the entire floor assembly, tires, body structure, steering system, chassis and exhaust system for damage.
  • After driving for an extended period through mud, sand, water or substances with a similar soiling effect, check the brake discs, brake pads, wheels and axle joints and have them cleaned.
  • If you experience severe vibrations after driving off-road, check the wheels for foreign bodies. These foreign bodies can produce an imbalance which might be responsible for the vibrations. Removing these deposits may remedy the problem.

Driving off-road on uphill gradients

Steep gradients
Dangerous uphill gradients could cause the vehicle to overturn.

  • Do not turn round when driving on uphill gradients.
  • If it is not possible to climb an uphill gradient, the vehicle must be backed down in reverse gear.
  • Do not drive over embankments or slopes at an angle.
  • If the vehicle starts to tilt, immediately steer in the direction of the tilt (line of slope).
  • When driving on uphill gradients, never let the vehicle roll back when in neutral or not in gear.
    Exclusive use of the footbrake is too risky in such situations.

When driving on uphill gradients, always remember the following:

  • Activate off-road mode before taking extreme uphill or downhill gradients.
  • Do not perform manual gear changes when driving, and try to avoid stopping.
  • Do not over-rev the engine.


Increasing traction on uphill gradients

To improve traction on a hill, always remember the following:

  • Switch off-road mode on.
  • When driving uphill, go easy on the accelerator and make sure that wheels have sufficient traction (do not spin).
  • Do not adjust the vehicle level on a slope.
  • Do not over-rev the engine.
  • Drive slowly.


Driving off-road on downhill gradients

Dangerous downhill gradients
Dangerous downhill gradients could cause the vehicle to overturn.

  • Do not drive over embankments or slopes at an angle.
  • Drive downhill slowly, with the front wheels pointing straight ahead.
  • If the vehicle starts to tilt, immediately steer in the direction of the tilt (line of slope).
  • When driving downhill, never let the vehicle roll in neutral.
  • Use engine braking effect.
  • If the engine braking effect is not sufficient to appropriately check the speed, gently apply the footbrake.
  • Activate Porsche Hill Control (PHC).
  1. Please see chapter "Porsche Hill Control (PHC)" on page 226.

When driving on downhill gradients, always remember the following:

  • Switch off-road mode on.
    Off-road ABS is switched on automatically.
  • Do not perform manual gear changes when driving, and try to avoid stopping.
  • Do not adjust the vehicle level on a slope.
  • When driving down steep hills on unpaved surfaces, brake carefully to prevent sliding.
