TIRE PRESSURES

WARNING

Make sure to read and fully understand the following warnings. Failure to comply with the safety instructions could result in an accident, leading to serious injury or death.

WARNING

All tire pressures, including the spare, should be checked regularly using an accurate tire pressure gauge, when the tires are cold. Failure to properly maintain the tire pressures could increase the risk of tire failure, resulting in a loss of vehicle control and potential personal injury.

WARNING

Pressure checks should only be carried out when the tires are cold, and the vehicle has been stationary for more than 3 hours. A hot tire at, or below, the recommended cold inflation pressure, is dangerously under-inflated.

WARNING

Never drive your vehicle if the tire pressures are incorrect. Under-inflation causes excessive flexing and uneven tire wear. This can lead to sudden tire failure. Over-inflation causes harsh ride, uneven tire wear, and poor handling.

WARNING

Do not drive the vehicle with a leaking tire. Even if the tire appears to be inflated it could be dangerously under-inflated and will continue to deflate. Replace the tire or contact an approved repairer.

WARNING

Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.

WARNING

If the vehicle has been parked in strong sunlight, or used in high ambient temperatures, do not reduce the tire pressures. Move the vehicle into the shade and allow the tires to cool before rechecking the pressures.

Check the tires, including the spare, for condition and pressure on a weekly basis and before long trips.

Dependent on the market, the tire pressures can be displayed in the instrument panel using the Vehicle info and Tire pressure check menus. See INSTRUMENT PANEL MENU. The display shows two tire pressures for each tire. The upper figure is the present tire pressure and the lower figure is the recommended tire pressure in brackets.

NOTES

The tire pressure units can be configured to display as either psi, bar, or kPa via the Display settings menu.

If the tire pressures are checked while the vehicle is inside a protected covered area, e.g., a garage, and subsequently driven in lower outdoor temperatures, tire under-inflation could occur.

A slight pressure loss occurs naturally with time. If this exceeds 2 psi (0.14 bar, 14 kPa) per week, have the cause investigated and rectified by qualified personnel.

If it is necessary to check the tire pressures when the tires are warm, expect the pressures to have increased by up to 4 - 6 psi (0.3 - 0.4 bar, 30 - 40 kPa). Do not reduce the tire pressures to the cold inflation pressure under these circumstances. Allow the tires to cool fully before adjusting the pressures.

The following procedure should be used to check and adjust the tire pressures:

  1. Remove the tire's valve cap.

  2. Firmly attach a tire pressure gauge and/or inflator to the valve.

    CAUTION

    To avoid damaging the valves, do not apply excessive force or sideways force on the gauge and/or inflator.

  3. Read the tire pressure from the gauge and add air, if required.

    CAUTION

    To avoid damage to the Tire Pressure Monitoring System (TPMS) valves, it is recommended not to use rigid tire inflation wands. This is to avoid the risk of excess leverage and sideways pressure on the valve.

  4. If air is added to the tire, remove the gauge and re-attach it before reading the pressure. Failure to do so may result in an inaccurate reading.

  5. If the tire pressure is too high, remove the gauge and press the center of the valve to allow air out of the tire. Refit the gauge to the valve and check the pressure.

  6. Repeat the process, adding or removing air as required, until the correct tire pressure is reached.

  7. Refit the valve cap.
