The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you need touse cables, it is recommended that steelwheels (of the same size and specifications)be used, as cables may chip aluminumwheels.
Follow these guidelines when using snowtires and traction devices
•If possible, avoid fully loading yourvehicle
•Purchase chains or cables from amanufacturer that clearly labels body totire dimension restrictions.
•Use 10 mm cables or chains only on frontaxle with 235/50R18 tires.
•Not all S-class snow chains or cablesmeet these restrictions. Chains of thissize restriction will include a tensioningdevice.
•The snow chains or cables must bemounted in pairs on the front axle.
•Do not use chains or cables on235/45R19, 245/45R19 and 255/40R20tires.
•Install cables securely, verifying that thecables do not touch any wiring, brakelines or fuel lines.
•When driving with tire cables do notexceed 30 mph (48 km/h) or themaximum speed recommended by thechain manufacturer, whichever is less.
•Drive cautiously. If you hear the cablesrub or bang against the vehicle, stop andretighten them. If this does not work,remove the cables to prevent vehicledamage.
•Remove the cables when they are nolonger needed. Do not use cables on dryroads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system isnot a substitute for manually checkingtire pressures. You should periodically checktire pressures using a pressure gauge.Failure to correctly maintain tire pressurescould increase the risk of tire failure, loss ofcontrol, vehicle rollover and personal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.

Wheels and Tires
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists.
When the malfunction indicator is illuminated,the system may not be able to detect orsignal low tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the TPMS from
functioning properly. Always check the TPMSmalfunction telltale after replacing one ormore tires or wheels on your vehicle toensure that the replacement or alternate tiresand wheels allow the TPMS to continue tofunction properly.
This device complies with Part 15 of the FCCRules and with License exempt RSSStandards of Industry Canada. Operation issubject to the following two conditions:

Changing Tires With a Tire PressureMonitoring System
Note:Each road tire is equipped with a tirepressure sensor located inside the wheeland tire assembly cavity. The pressuresensor is attached to the valve stem. Thepressure sensor is covered by the tire andis not visible unless the tire is removed. Takecare when changing the tire to avoiddamaging the sensor.
You should always have your tires servicedby an authorized dealer.
Check the tire pressure periodically (at leastmonthly) using an accurate tire gauge. SeeWhen Inflating Your Tires in this chapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your road tires andsends the tire pressure readings to yourvehicle. You can view the tire pressurereadings through the information display.See General Information (page 109). The lowtire pressure warning light will turn on if thetire pressure is significantly low. Once the
light is illuminated, your tires areunder-inflated and need to be inflated to themanufacturer’s recommended tire pressure.Even if the light turns on and a short timelater turns off, your tire pressure still needsto be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.

When Inflating Your Tires
WARNING
Do not use the tire pressure displayedin the information display as a tirepressure gauge. Failure to follow thisinstruction could result in personal injury ordeath.
When putting air into your tires (such as at agas station or in your garage), the tirepressure monitoring system may not respondimmediately to the air added to your tires.
It may take up to two minutes of driving over20 mph (32 km/h) for the light to turn off afteryou have filled your tires to therecommended inflation pressure.
How Temperature Affects Your TirePressure
The tire pressure monitoring system monitorstire pressure in each pneumatic tire. Whiledriving in a normal manner, a typicalpassenger tire inflation pressure mayincrease about 2–4 psi (14–28 kPa) from acold start situation. If the vehicle is stationary
overnight with the outside temperaturesignificantly lower than the daytimetemperature, the tire pressure may decreaseabout 3 psi (21 kPa) for a drop of 30°F (17°C)in ambient temperature. This lower pressurevalue may be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflationpressure and activate the system warninglight for low tire pressure. If the low tirepressure warning light is on, visually checkeach tire to verify that no tire is flat. If one ormore tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drive thevehicle to the nearest location where air canbe added to the tires. Inflate all the tires tothe recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNINGS
The tire pressure monitoring system isnot a substitute for manually checkingtire pressures. You should periodically checktire pressures using a pressure gauge.Failure to correctly maintain tire pressurescould increase the risk of tire failure, loss ofcontrol, vehicle rollover and personal injury.
If the tire pressure monitor sensorbecomes damaged it may not function.
Note:You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
