* Option/accessory.554

NOTE
Always remember to calibrate the Tire Pres-sure Monitoring System when the wheelshave been changed or the tire inflation pres-sure has been corrected according to the tirepressure decal or tire inflation pressure table.
If correct reference values have not been set,the system cannot issue low tire pressurealerts correctly.
The vehicle must be stationary with theengine running to access the calibration but-ton and to start the calibration process.

WARNING
The exhaust gases contain carbon monoxide,which is invisible and odorless but very poi-sonous. For this reason, always perform thecalibration procedure outdoors or in a work-shop with exhaust gas evacuation equipment.

Action when warned of low tirepressure
When the system for monitoring inflation pres-
sure 13 detects low inflation pressure in a tire,immediate action is required.
If the system's indicator symbol illumi-nates and the message Tire pressurelow is displayed, check the tire pres-sure and inflate if necessary.
1. Switch off the ignition.
2. Check the inflation pressure on all four tiresusing a tire pressure gauge.
3.Inflate the tire to the correct inflation pres-sure; see the tire pressure placard on thedriver's side B pillar for recommended pres-sures for factory-mounted tires.
4. Through calibration of the system via thecenter display after the tire pressure hasbeen adjusted.
Please be aware that the indicator symbolwill not go out until the low tire pressure hasbeen corrected and the system has beenrecalibrated.
NOTE
To help prevent incorrect inflation pressure,pressure should be checked when the tiresare cold. The tires are considered to be coldwhen they have reached the same tempera-ture as the ambient temperature (about 3hours after the vehicle was last driven). Afterdriving for a few kilometers, the tires will warmup and the pressure will increase.

NOTE
After inflating a tire, always replace thevalve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.

WARNING
Incorrect inflation pressure could lead totire failure, which could cause the driverto lose control of the vehicle.
The system cannot predict sudden tiredamage.

Jack*
The jack can be used to lift the vehicle to e.g.change a wheel.
The illustration is generic – the design may vary.

CAUTION
When not in use, the jack* should be keptin its storage compartment under thecargo compartment floor.
The jack provided with your vehicle isintended to be used only in temporary sit-uations such as changing wheels in theevent of a flat tire. Only the jack thatcame with your particular model shouldbe used to lift the vehicle. If the vehicleneeds to be lifted more frequently or for aprolonged period, using a garage jack orhoist is recommended. Always follow thisdevice's instructions for use.
The jack needs to be cranked together to thecorrect position in order to fit.

Models with leveling control *
If the vehicle is equipped with the optional pneu-matic suspension, it must be turned off beforethe vehicle is lifted on a jack.
