Downloaded from www.Manualslib.com manuals search engine As a driver assistance feature, your vehiclehas a tire pressure monitoring system. Awarning lamp will illuminate when one ormore of the tires are significantlyunder-inflated. If the low tire pressurewarning lamp illuminates, you should stopyour vehicle as soon as it is safe to do so,check the tires and inflate them to thecorrect pressure.
Driving on under-inflated tires can:
•Cause them to overheat.
•Lead to tire failure.
•Reduce fuel efficiency.
•Reduce tire life.
•Affect vehicle handling or stoppingability.
The system is not a substitute for correcttire maintenance.
You must maintain the correct tirepressures, even if low tire pressure has notilluminated the warning lamp.
The tire pressure monitoring system has asystem malfunction indicator to warn youwhen the system is not operating correctly.The malfunction indicator and low tirepressure warning lamp have a combinedfunction. When the system detects amalfunction, the warning lamp will flashfor approximately one minute and thenremain illuminated. This sequence willoccur every time you switch the ignition onwhile the malfunction remains. The systemhas detected a fault that requires service.
When the malfunction indicator isilluminated, the system may not be ableto detect or signal low tire pressures. Amalfunction may occur for a variety ofreasons, including the installation of areplacement tire or wheel that preventsthe system from functioning correctly.Always check the tire pressure monitoringsystem malfunction warning after
replacing one or more tires or wheels onyour vehicle. Make sure the replacementtires or wheels allow the system tocontinue to function correctly. See Whenthe Temporary Spare Tire is Installedin this section.
Changing Tires With a TirePressure Monitoring System
You should always have tires serviced byan authorized dealer.
Note:Each road wheel and tire is fitted witha tire pressure sensor located inside thewheel and tire assembly cavity. The pressuresensor attaches to the valve stem. The tirecovers the pressure sensor and it is notvisible unless the tire is removed. Take carewhen changing the tire to avoid damagingthe sensor.
Understanding the Tire PressureMonitoring System
The system measures the pressure in thefour road tires and sends the tire pressurereadings to your vehicle.
The system detects this lower pressure asbeing significantly below the correctinflation pressure and the warning lampilluminates. You must inflate the tires tothe correct pressure.

If you need to replace a road wheel andtire with the temporary spare wheel, thesystem will continue to identify a defect.This is to remind you to repair the damagedroad wheel and tire and refit the repairedroad wheel and tire assembly to yourvehicle. To restore the correct operationof the system, you must have the repaired
road wheel and tire assembly refitted toyour vehicle.
When You Believe the System is NotOperating Correctly
The main function of the system is to warnyou when the tire pressures are low. It canalso warn you in the event the system isno longer capable of operating correctly.See the following chart for informationconcerning the system:

1.Make sure tires are at the correctpressure. See Wheels and Tires(page 260). The tire pressures are alsoon the tire inflation pressure label(located on the edge of driver dooror the B-Pillar).
2.After inflating the tires to the correctpressure you must carry out the tirepressure monitoring system resetprocedure. See Tire PressureMonitoring System ResetProcedure in this chapter.

Downloaded from www.Manualslib.com manuals search engine Tire Pressure Monitoring SystemReset Procedure
Overview
You must carry out the system resetprocedure after each tire replacement oradjustment of the tire pressures.
To maintain your vehicle load carryingcapability, your vehicle requires differenttire pressures in the front tires comparedto the rear tires.
The system illuminates the warning lampat different pressures for the front and reartires.
The tires need to be periodically rotatedto provide consistent performance andmaximum tire life, the system needs toknow when the tires have been rotated todetermine which set of tires are on thefront and rear axles. With this information,the system can detect and correctly warnof low tire pressures.
Carrying Out the System ResetProcedure
Switch the ignition on. Using theinformation display control select:
Description and ActionMessage
Press the OK button.Settings
Press the OK button.Driver assist
Press and hold the OK button until confirmation appears.Alternatively, if your vehicle has a tire pressure monitoringsystem reset button, press and hold the button untilconfirmation appears.
Tire Monitor
How Temperature Affects the TirePressures
Under normal driving conditions tirepressures may increase by up to 4 psi(0.3 bar) from a cold start situation.
If the vehicle is stationary overnight andthe temperature significantly lower thanthe daytime temperature, tire pressuresmay decrease by up to 3 psi (0.2 bar) whenthere is a drop in the ambient temperatureof 63°F (17°C) or more. The systemdetects this pressure decrease as beingsignificantly below the correct inflationpressure and the warning lamp illuminates.
When Inflating the Tires
When inflating the tires the system maynot respond immediately to the air addedto the tires.
If the Warning Lamp is On:
1.Check each tire to verify that none areflat.
2.If one or more tires are flat, repair asnecessary.
3.Check the tire pressures and inflate allthe tires to the correct pressure.
4.Carry out the tire pressure monitoringsystem reset procedure.

You can obtain a replacement locking lugnut key and replacement locking lug nutsfrom your dealer using the referencenumber certificate.
Vehicles with a Spare Wheel
If the spare wheel is exactly the same typeand size as the other fitted road wheels,you can replace the existing road wheelwith the spare wheel and continue to drivein the normal manner.
If the spare wheel is different to the otherroad wheels, it will carry a yellow label withthe appropriate speed limit.
Refer to the following information beforechanging the road wheel.
WARNINGS
Drive the shortest possible distances.
Do not fit more than one spare wheelon your vehicle at any one time.
Do not carry out any tire repairs on aspare wheel.
Do not drive through an automaticcar wash.
If you are unsure what type of sparewheel you have do not exceed 80km/h (50 mph).
Only fit snow chains to specifiedtires. See Using Snow Chains(page 264).
The ground clearance of your vehiclemay be reduced. Take care whenparking next to a curb.
Note:Your vehicle may exhibit someunusual driving characteristics.
Vehicle Jack
WARNINGS
The vehicle jack supplied with yourvehicle should only be used whenchanging a wheel in emergencysituations.
Before using the vehicle jack, checkthat it is not damaged or deformedand that the thread is lubricated andfree from foreign matter.
Never place anything between thejack and the ground, or the jack andyour vehicle.
Note:Vehicles with a temporary mobilitykit do not have a vehicle jack or a lug nutwrench
It is recommended to use a workshop typehydraulic jack for changing betweensummer and winter tires.
Note:Use a jack with a minimum liftingcapacity of 1.5 tonnes and a lifting plate witha minimum diameter of 3.1 inches (80millimeters).
Vehicles without a Temporary MobilityKit
Your vehicle jack, lug nut wrench andscrew-in towing eye are located in thespare wheel well or behind the rear seatwith the fuel funnel.
Jacking and Lifting Points
WARNING
Use only the specified jacking points.If you use other positions, you maydamage the body, steering,suspension, engine, braking system or thefuel lines.

Installing a Road Wheel
WARNINGS
Make sure that the arrows ondirectional tires point in the directionof rotation when your vehicle ismoving forward. If you have to fit a sparewheel with the arrows pointing in theopposite direction, have the tire refitted inthe correct direction by an authorizeddealer.
Use only approved wheel and tiresizes. Using other sizes coulddamage the vehicle and will makethe National Type Approval invalid. SeeTire Pressures (page 273).
Make sure there is no lubrication(grease or oil) on the threads or thesurface between the wheel lugs andnuts. This can cause the lug nuts to loosenwhile driving.
Do not fit run flat tires on vehiclesthat were not originally fitted withthem. Contact an authorized dealerfor more details about compatibility.
WARNINGS
Do not install alloy wheels using lugnuts designed for use with steelwheels.
Lug nuts are subject to change. Youmust make sure that you use onlythe specific lug nuts and wheelssupplied for your vehicle. If in doubt pleasecontact your authorized dealer.
Note:The lug nuts of alloy wheels andspoked steel wheels can also be used forthe steel spare wheel for a short time(maximum two weeks).
