Fuel gauge
The fuel gauge displays the contents of the tank when the ignition is on.

For information on fuel quality and refill capacities:

  • Please see the chapter "FILLING CAPACITIES" on page 343.

For information on refueling:

  • Please see the chapter "FUEL" on page 267.

If the vehicle’s inclination changes (e.g. uphill/ downhill driving), minor deviations in the gauge may occur.

Fuel reserve warning
If less than approximately 4 US gallons (15 liters) of fuel (3.43 US gallons (13 liters) for the Cayenne Diesel and Cayenne S Hybrid) remains in the tank or if the range on remaining fuel is less than approx. 30 miles (50 km), a warning message appears on the multi-function display of the instrument panel and the warning light in the fuel gauge comes on.

  • Refuel at the next opportunity.


A shortage of fuel may damage the emission control system.

  • Never drive the tank dry.
  • If the warning light has come on, do not take corners at high speed.

For information on the emission control system:

  • Please see the chapter "EMISSION CONTROL SYSTEM" on page 264.

Battery/Alternator

Warning message

The warning message "Fault Generator" will appear on the multi-function display of the instrument panel if the vehicle electrical system voltage drops significantly or if there is a problem with the alternator.

Possible causes

  1. Defect in the battery charging system
  2. Broken drive belt

Broken Drive Belt
A broken drive belt means there is no power assistance to the steering (more effort is required to steer) and engine cooling fails.

  • Do not continue driving.
  • Have the fault remedied at your nearest authorized Porsche dealer.

Slipping Drive Belt
Danger of steering assistance failing during a long journey in water if the drive belt slips.

  • If steering assistance fails, more effort will be required to steer.


Risk of engine damage.

A broken drive belt will cause the engine cooling system to fail.

  • Do not continue driving.
  • Have the fault corrected.
  • Please contact your authorized Porsche dealer.

Check Engine (Emission control)

Warning light

The emission control system detects malfunctions early that could cause increased pollutant emissions or consequential damage etc.

Faults are indicated by the warning light on the instrument panel which then either lights up continuously or flashes.

The faults are recorded in the control unit’s fault memory.

The warning light in the instrument panel lights up for a lamp check when the ignition is switched on.

The warning light on the instrument panel flashes to indicate operating states (e.g. engine misfiring) that may damage certain parts of the emission control system.

  • In this case, immediately reduce the engine load by easing off the accelerator pedal.

In order to avoid consequential damage to the engine or the exhaust-gas cleaning system (e.g. catalytic converter):

  • Please see your authorized Porsche dealer.
