as possible, and inflate them to the proper pressure,
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduced fuel efficiency and tire tread life,
and may affect the vehicle's handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure indicator light.
The TPMS 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 inside the vehicle.NOTE:The TPMS can inform you about a low tire
pressure condition, but it does not replace normal tire
maintenance. The TPMS is not intended to provide you
with notification of rapid tire pressure loss.

CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge. After adjusting the air pressure in a tire, there
will be a delay before the system updates the display.
The system will automatically update and the Tire
Pressure Monitoring Indicator Light will turn off,
once the system receives the updated tire pressures.
The vehicle needs to be driven above 20 mph in order
for the TPMS to receive this information.The TPMS will cause the indicator light in the instrument
cluster to illuminate whenever the pressure in one tire
falls 25% below the recommended pressure shown on the
vehicle's tire label.
The TPMS will cause the indicator light to flash for
approximately one minute and then remain continuously
illuminated whenever the system detects a TPMS mal-
function.
NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPMS set-point.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPMS indicator light on the following day
216 STARTING AND OPERATING

if the temperature is very cold.ALWAYScheck the
pressure in your tires if the TPMS indicator light is
illuminated.CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. The TPMS pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket tire sealant or balance beads, as
damage to the sensors may result.
NOTE:The standard TIREFIT system (refer to What To
Do In Emergencies for more information) is specifically
designed to operate in conjunction with the TPMS, and
will not damage the sensors.

If your tire pressure is low, you should correct your tire
inflation pressure as soon as possible and inspect all of
your tires. Low tire pressure will cause the tire pressure
light to illuminate. They will remain on for the rest of the
driving cycle, or until the tire pressure is corrected. If the
TPMS indicator light remains illuminated after the tire
pressure has been corrected, see your authorized dealer.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure indicator light.
When the system detects a malfunction, the indicator
light will flash for approximately one minute and then
remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indicator is
illuminated, the system may not be able to detect or
signal low tire pressure as intended. TPMS malfunctionsmay occur for a variety of reasons, including the instal-
lation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction indicator light after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.
NOTE:Changes and modifications not expressly ap-
proved by the party responsible for compliance could
void the user's authority to operate the equipment.

TIRE CHAINS
The RUD-matictDISC is the only tire chain system
approved for use on your vehicle.
Chains should only be used on the rear wheels and only
with the recommended winter mud and snow (M+S)
tires and wheels. Follow the manufacturer's mounting
instructions.Tire chains should only be driven on snow-covered roads
at speeds not to exceed 30 mph (48 km/h). Remove
chains as soon as possible when driving on roads without
snow.
When driving with tire chains, press the ESP control
switch to OFF.
CAUTION!
Damage to the vehicle may result if unapproved tire
chains are used.

ORIGINAL EQUIPMENT TIRES
Your vehicle is equipped with either sport performance
tires or all-season performance tires. The sport perfor-
mance tires offer the maximum road handling capability
in dry and wet weather conditions. The all-season per-
formance tires, while offering slightly less road handling
capability, are able to provide traction capability in snow
and ice conditions. Both types of tires are rated for high
speed operation. It is important that you know what type
of tires your vehicle is equipped with so that you
understand their traction and handling characteristics for
various road conditions. Replacement tires should be of
the same size and speed rating to continue to provide the
same level of performance you are accustomed to.
SNOW TIRES
Some countries or regions require the use of snow tires
during winter. See the recommended snow type winter
tire applications in this section.
WARNING!
Your vehicle may be equipped with sport perfor-
mance tires that are optimized for driving in dry and
wet weather conditions. However, these tires have
reduced traction capability in snow and ice. When
driving your vehicle in these conditions with these
tires, you must take special care to maintain control
and avoid accidents. We recommend that you equip
your vehicle with ªSNOWº or ªALL SEASONº tires
on all four wheels for driving in snowy and icy
conditions.
220 STARTING AND OPERATING

If you need snow tires, the recommended size for the
front and rear tires is the same size as the original
equipment front tires. This size tire on the rear allows the
use of tire chains on the rear wheels. Selection of this size
tire also requires the purchase of two additional wheels
with the same size specification as the original equip-
ment front wheels.
Snow tires may have a lower speed rating than factory
equipped tires and may not match the maximum vehicle
speed.
Snow tires should not be operated at sustained speeds
over 75 mph (120 km/h).TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates, and tend to develop irregular wear pat-
terns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.
Follow the recommended tire rotation frequency for your
type of driving found in the ªMaintenance Schedulesº
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.

FUEL REQUIREMENTS
Your engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and optimum performance
when using high quality unleaded gaso-
line having an octane rating of 91 or
higher. DaimlerChrysler Corporation re-
quires the use of 91 octane or higher premium fuel to
minimize the potential for engine damage.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and should be reported to
your authorized dealer immediately. Engine damage
resulting from operating with a heavy spark knock may
not be covered by the new vehicle warranty.
