the vehicle, check that the jack is still cor- rectly positioned in the attachment.
7. Raise the vehicle until the wheel to be changed is lifted off the ground.
8. Unscrew the wheel bolts completely and carefully remove the wheel so as not todamage the threads on the studs.
NOTE
To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheelsin the same location and position as beforeremoval. To lessen the chance of imbal-ance, each wheel hub is equipped with aguide stud to ensure that a removed wheelcan be reinstalled in its original position (aswhen changing over to winter tires/wheels).
CAUTION
•The vehicle must not be driven with wheels of different dimensions or witha spare tire other than the one thatcame with the vehicle. The use of dif-ferent size wheels can seriously dam-age your vehicle's transmission.
• Correct tightening torque on wheelbolts must be observed.
• The wheel bolts should never begreased or lubricated.
• Extended, chromed wheel bolts mustnot be used with steel rims, as theymake it impossible to fit the hub caps.
Installing the wheel1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel bolts and tighten hand- tight. Using the lug wrench, tighten cross- wise until all bolts are snug.
4. Lower the vehicle to the ground and alter- nately tighten the bolts crosswise to103 ft.lbs. (140 Nm).
5. Install the wheel cover (where applicable).
WARNING
• The jack must correctly engage the bar in the jack attachment. The vehicle'sweight must not rest on the jackattachment. See illustration "Attachingthe jack" on the previous page.
• Be sure the jack is on a firm, level,non-slippery surface.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
• Use the jack intended for the vehiclewhen replacing a wheel. For any otherjob, use stands to support the side ofthe vehicle being worked on.
• Apply the parking brake and put thegear selector in the (
P)ark position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.

Tire Pressure Monitoring System (TPMS)
07
203
The tire pressure monitoring system
1
uses
sensors mounted in the tire valves to check inflation pressure levels. When the vehicle ismoving at a speed of approximately 20 mph(30 km/h) or faster, these sensors transmitinflation pressure data to a receiver located inthe vehicle.
USA – FCC ID: MRXG403MA4 A
This device complies with part 15 of the
FCC rules. Operation is subject to the fol- lowing conditions: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation. When low inflation pressure is detected, TPMS will light up the tire pressure warn-ing light (also referred to as a telltale) in theinstrument panel (see page 61), and willdisplay a message in the text window. Thewording of this message is determined bythe degree of inflation pressure loss.
A On certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS will light up the tire pressure warning light
(also referred to as a telltale) in the instrument panel and will display one of the following messages in the text window:
LOW
TIRE PRESS. CHECK TIRES or VERY LOW
TIRE PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illu-minates, you should stop and check yourtires as soon as possible, and inflate them to the proper pressure. Driving on a significantlyunder-inflated tire causes the tire to overheatand can lead to tire failure. Under-inflationalso reduces fuel efficiency and tire tread life,and may affect the vehicle's handling andstopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination of theTPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem 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 illu-minated, the system may not be able todetect or signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of replace-ment or alternate tires or wheels on the vehi-cle that prevent the TPMS from functioning
