Tire repair
10-5
Roadside emergencies
Note: In cold conditions, use the vehicle’s
heater to warm the aerosol.
3. Position the wheel (if possible) so that the puncture is at the bottom.
4. Remove the valve cap and clean the valve thread.
5. Vigorously shake the tire sealant for approximately 30 seconds.
6. Screw the filler tube onto the tire valve and break the safety seal.
7. Hold the tire sealant upright and turn the knob one-quarter turn clockwise. If you
need to stop the process, simply turn the
knob back to the ‘OFF’ position.
8. Empty the entire contents of the tire sealant into the tire. When the sealant
stops flowing through the filler tube, turn
the knob to the ‘OFF’ position and
unscrew the filler tube from the tire valve.
Note: If tire sealant comes into contact
with the vehicle’s paint, immediately
wash the area with water to avoid
permanent damage.
9. If the wheel rim has lifted from the ground, drive immediately for 6 to 12
miles (10 to 20 km) to distribute the
sealant evenly inside the tire. Then drive
gently and do not exceed 30 mph
(45 km/h).
WARNING: If the wheel rim has not
lifted from the ground, call
Roadside Assistance to have the vehicle
transported to a repair facility.
S
10. Drive to the nearest service station and inflate the tire to the correct pressure (see
Specifications and tire pressures,
page 11-4 .) If the required pressure
cannot be reached, then the tire is too
severely damaged and you should have
the vehicle transported to a tire repair
facility. Do not drive!
Note: When adjusting tire pressures, you
can display tire pressure values on the
Touch Screen’s tire pressure screen.
However, the values displayed by the
Touch Screen will not be updated until
you place the car in drive long enough for
the tire pressure monitoring sensors to
take new readings. For details, refer to the
Touch Screen Users Manual provided in
your owners package.
11. If the correct tire pressure was achieved, continue driving. Drive carefully and do
not exceed 30 mph (45 km/h). At the
earliest opportunity, have the tire
repaired or replaced and replace the used
tire sealant.
WARNING: Always inform the tire
repairer that tire sealant has been
used. If the tire is to be subsequently
deflated, only do so in a well ventilated
area. The aerosol sealant can damage the
wheel sensor that measures tire pressure.
Therefore, the wheel sensor must be
replaced.
S
Replacing the tire sealantAlways replace the used tire sealant with one
of the same type and capacity (400 ml). Tire
sealants are available through most reputable
automotive retailers.

handling.
Driving the vehicle with the tires inflated to the comfort setti ng will improve ride comfort and road handling, but will decrea se vehicle range (the
number of miles you can travel on a charge) and Battery life (see the New Vehicle Limited Warranty, provided in your owners pac kage, for details
on expected range of the Battery).

Wheels and tires11-6Technical specifications7, U.S DOT Tire Identification Number
(TIN)This begins with the letters DOT and
indicates that the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was
manufactured, and the last four numbers
represent the week and year the tire was
built. For example, the numbers 1706 means
the 17th week of 2006. The other numbers
are marketing codes used at the
manufacturer's discretion. This information
can be used to contact consumers if a tire
defect requires a recall.8, Maximum permissible inflation
pressureThe maximum inflation pressure for the tire.
This pressure should not be used for normal
driving.
9, Treadwear gradeThis number indicates the tire's wear rate.
The higher the treadwear number is, the
longer it should take for the tread to wear
down. A tire rated at 400 for example, will
last twice as long as a tire rated at 200.10, Traction gradeThis letter indicates a tire's ability to stop on
wet pavement. A higher graded tire should
allow you to stop your vehicle on wet roads in
a shorter distance than a tire with a lower
grade.
Traction is graded from highest to lowest as
AA, A, B, and C.11, Temperature gradeHeat resistance grading. The tires resistance
to heat is grade A, B, or C, with A indicating
the greatest resistance to heat. This grading
is provided for a correctly inflated tire, which
is being used within its speed and loading
limits.12, Tire composition and materialsThe number of plies in both the tread area,
and the sidewall area, indicates how many
l aye rs o f ru bb e r co ate d m ate ri al m ake u p t h e
structure of the tire. Information is also
provided on the type of materials used.

Tire Pressure Monitoring
System
WARNING: The TPMS is not a substitute
for manually checking tire pressures.
The TPMS only provides a tire pressure
warning and does not re-inflate the tires.
S
WARNING: The TPMS cannot register
damage to a tire. Regularly check the
condition of your tires.
S
The Tire Pressure Monitoring System (TPMS)
monitors the pressure of the tires using
sensors located in each wheel and receivers
located within the vehicle. The sensors
communicate with the receiver using Radio
Frequency (RF) signals.
Note: Installing accessories that are not
approved by Tesla Motors may interfere with
the TPMS system. Tire pressure warnings are displayed
on the instrument panel using an
amber warning indicator (telltale). A warning
is also displayed on the Touch Screen.
If the tire pressure warning light illuminates,
stop and check your tires as soon as possible
and inflate them to the correct pressure. If the
low pressure warning occurs frequently, the
cause must be determined and rectified.
The tire pressure warning indicator will
extinguish when all tires have been inflated to
the correct pressure.
TPMS malfunctionYour vehicle has been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is combined
with the tire pressure indicator. When the
system detects a malfunction, the indicator
will flash. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists.
When a malfunction occurs, the system may
not be able to detect or signal low tire
pressure as intended. TPMS malfunctions can
occur for a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction indicator after
replacing one or more tires or wheels to
ensure that the replacement or alternate tires
and wheels allow the TPMS to function
properly. Note:
If a tire has been replaced or repaired
after using the tire sealant, and a low tire
pressure is detected, it is possible that the
wheel sensor has been damaged. The aerosol
sealant can damage the wheel sensor that
measures tire pressure. Therefore, whenever
tire sealant has been used, the wheel sensor
must be replaced.
Setting the tire pressuresYour vehicle allows you to use two sets of tire
pressures, refer to Specifications and tire
pressures, page 11-4 .Replacing a tire sensorIf you are experiencing frequent low tire
pressure warnings or the Touch Screen
reports a “Tire Pressure Hardware Fault”, the
system should be checked by Tesla Motors to
determine if a tire sensor requires
replacement.Type approvalThe TPMS devices comply with Part 15 of the
FCC rules and RSS-210. Operation is subject
to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept interference received, including interference that may
cause undesired operation.
