Make sure the following warnings have been read and fully understood before driving the vehicle. Failure to do so may result in an accident, leading to serious injury or death.


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


Never drive the vehicle if the tyre pressures are incorrect. Under-inflation causes excessive flexing and uneven tyre wear, resulting in sudden tyre failure. Over-inflation causes harsh ride, uneven tyre wear, and poor handling.


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


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


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


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

Tyre pressure information locations:

  • Tyre placard: Lists the recommended cold inflation pressures for all loading conditions. The label is located at the base of the driver’s door opening.

  • Instrument panel menu: Displays the recommended inflation pressures for the current ambient conditions. See TYRE PRESSURE CHECK.

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

Tyre under-inflation could occur if the tyre pressures are checked in a covered area, and the vehicle is subsequently driven in lower outdoor temperatures.

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

Expect the pressures to be increased by up to 0.3 - 0.4 bar (4 - 6 psi, 30 - 40 kPa) if checking the pressures when the tyres are warm. Do not reduce the tyre pressures to the cold inflation pressure under these circumstances. Allow the tyres to cool fully before adjusting the pressures.

For vehicles with a Tyre Pressure Monitoring System (TPMS), adjust the pressure of a warm tyre to the warm inflation pressure. See TYRE PRESSURE CHECK.

To check and adjust the pressures:


The loading of the vehicle should always be considered when checking and adjusting the tyre pressures. Failure to do so may lead to a loss of control, potentially causing serious injury or death.


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


To avoid damage to the TPMS valves, it is recommended not to use rigid tyre inflation wands. Rigid tyre inflation wands increase the risk of excess leverage and sideways pressure on the valve.

  1. Remove the tyre valve cap.

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

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

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

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

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

  7. Refit the valve cap.


Always maintain the full-size spare tyre's pressure at the correct pressure for the current load conditions. Refer to the tyre placard label.
