Alignment And Balance; Tire Pressure Monitor System - If Equipped - Jeep 2004 Grand Cherokee Owner's Manual

Alignment and Balance

The suspension components of your vehicle should be
inspected and aligned when needed, to obtain maximum
tire tread life.
Poor suspension alignment may result in:
• reduced tread life;
• uneven tire wear, such as feathering and one-sided
wear;
• vehicle pull to the right or to the left.
Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your dealer
for proper diagnosis of the problem.
Improper alignment will not normally cause vehicle
vibration, which may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.
STARTING AND OPERATING 217
TIRE PRESSURE MONITOR SYSTEM — IF
EQUIPPED
The Tire Pressure Monitor System (TPM) monitors the
pressure in all 4 road tires and the full size spare (5 Tire
TPM System Only). The TPM system uses wireless
technology to monitor tire pressure levels. Sensors,
mounted to each wheel as part of the valve stem, transmit
tire pressure readings to a receiver located in the over-
head console. The tire pressure status is shown in the
Electronic Vehicle Information Center (EVIC) display.
Refer to "Overhead Console" in Section 3 for more
information. The TPM system functions even when the
EVIC is not set on the tire pressure display screen.
The TPM system informs you of a low or high tire
pressure condition. If this occurs, correct your tire infla-
tion pressure as soon as possible, and inspect all of your
tires. Be sure to use a high quality gauge when adjusting
pressure. The TPM system is designed to monitor your
tire pressure but will not function as a tire pressure
