In addition to the warning lamp ,am essage
appears in the multifunction display. Observe
the information on display messages
( Y
page 196).
It may take up to ten minutes for am alfunction
of the tire pressure monitor to be indicated .A
malfunction wil lbei ndicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure
warning lamp goes out after af ew minutes of
driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at ag as station with ap ressure gauge. The
tire pressures shown by the on-board computer
refer to those measured at sea level .Ath igh
altitudes, the tire pressure values indicated by a
pressure gauge are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radi ot ransmit-
ting equipment (e.g. radi oh eadphones, two-way
radios) that may be being operated in or near the
vehicle.
Checking the tire pressure electroni-
cally X
Make sure that the SmartKey is in position 2
in the ignition lock ( Y

Press the Y or e button on the steering
wheel to select the Serv. menu.X
Press the c or d button to select
Tire Pressure .X
Press the v button.
The current tire pressure of each tire is shown
in the multifunction display.
If the vehicle has been parked for over
20 minutes, the Tire pressure will be
displayed after driving af ew minutes
messag ea ppears.
After at each-in process, the tire pressure mon-
itor automatically detects new wheel sorn ew
sensors. As long as ac lear allocation of the tire
pressure valu etot he individual wheel sisn ot
possible, the Tire Pressure Monitor Active
display messag eiss hown instead of the tire
pressure display. The tire pressures are already
being monitored.
If an emergency spare wheel is mounted, the
system may continue to show the tire pressure of the wheel that has been removed for af ew
minutes. If this occurs, note that the valu ed is-
played for the positio nw here the spare wheel is
mounted is not the same as the current tire
pressure of the emergency spare wheel.
Tire pressure monitor warning mes-
sages If the tire pressure monitor detects ap ressure
loss in one or more tires, aw arning messag ei s
shown in the multifunction display. The yellow
tire pressure warning lamp then lights up. R
If the Please Correct Tire Pressure
messag ea ppears in the multifunction display,
the tire pressure in at least one tire is too low.
The tire pressure must be corrected when the
opportunity arises. R
If the Check Tires messag ea ppears in the
multifunction display, the tire pressure in at
least one tire has droppe ds ignificantly. The
tires must be checked. R
If the Warning Tire Malfunction message
appears in the multifunction display, the tire
pressure in at least one tire has droppe ds ud-
denly .T he tires must be checked.
Observe the instructions and safety notes in the
display messages in the "Tires" section
( Y
page 196).
If the wheel positions on the vehicle are rotated,
the tire pressures may be displaye df or the
wrong positions for as hort time. This is rectified
after af ew minutes of driving, and the tire pres-
sures are displaye df or the correct positions.
Restarting the tire pressure monitor When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp sgoo ut. The monitor uses the cur-
rently set tire pressures as the reference values
for monitoring. In most cases, the tire pressure
monitor wil la utomatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also define refer-
ence values manually as describe dh ere. The tire
pressure monitor then monitors the new tire
pressure values. X

Determinin gt he correct load limit
Step-by-ste pi nstructionsThe following steps have been developed as
required of all manufacturers under Title 49,
Cod eofU .S. Federa lR egulations, Part 575 pur-
suant to the "National Traffi ca nd Motor Vehicle
Safety Act of 1966". X
Step 1: Locate the statement "The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on you rv ehicle’s
Tire and Loading Informatio np lacard.X
Step 2: Determine the combined weight of
the drive ra nd passengers that wil lber iding in
you rv ehicle. X
Step 3: Subtract the combined weight of the
drive ra nd passengers from XXX kilograms or
XXX lbs. X
Step 4: The resulting figure equals the avail-
abl ea mount of cargo and luggage loa dc apa-
city. For example, if the "XXX "a mount equals
1400 lbs and there wil lbef ive 150-lb pas-
sengers in you rv ehicle, the amount of avail-
abl ec argo and luggage loa dc apacity is
650 lbs (1400 -7 50 (5 x1 50) = 6 50 lbs).X
Step 5: Determine the combined weight of
luggage and cargo being loaded on the vehi-
cle. That weight may not safel ye xceed the
available cargo and luggage loa dc apacity cal-
culated in step 4.
Example :s teps 1to3The following table show se xamples on how to
calculate total and cargo loa dc apacities with
varying seating configurations and number and
size of occupants. The following examples use a
loa dl imi tof1 500 lbs (680 kg). This is for illus-
tration purposes only. Make sure you are

All passenge rc ar tires must conform to the stat-

Treadwear The treadwea rg rad eisac omparativ er ating

The relative performance of tires depends upon
the actua lc onditions of their use ,h owever, and
may depart significantly from the norm du et o
variations in driving habits, service practices
and differences in road characteristics and cli-
mate.
Traction
G WARNING
The tractio ng rad ea ssigne dtot his tire is
based on straight-ahead braking traction
tests, and doe sn ot include acceleration, cor-
nering, hydroplaning ,orp ea kt ractio nc har-
