How the Airbags WorkInflation of airbags depends on the rate at
which the vehicle’s cabin changes speed in a
collision. The rate of deceleration determines
whether airbags inflate.
Airbags inflate instantly with considerable
force accompanied by a loud noise. The
inflated bag, together with the seat belts, limits movement of occupants to reduce the
risk of injury.
Front airbags are not ordinarily designed to inflate in rear collisions, rollovers, minor frontor side collisions, heavy braking, or driving
over bumps and potholes. Therefore, significant superficial damage can occur tothe vehicle without the airbags inflating or,
conversely, a relatively small amount of
structural damage can cause airbags to inflate.
If you are planning to modify your vehicle for a person with disabilities in a way that may
affect the airbag system, contact Tesla.Types of AirbagsAdvanced
front
airbagsThe front airbags are
advanced airbags designed to
reduce airbag related injuries
to children or small adults who
ride in the front seats. On the
driver’s side, the front airbag
works with a seat position
sensor that adjusts the
inflation level based on the
seating position of the
occupant. For safety of infants
and small children, the front
passenger airbag must be
disabled, as described below.Side
airbagsSide airbags protect the
thorax region of the torso and
the pelvis. They inflate only if
a severe side impact occurs.
Side airbags on the non-
impacted side do not inflate.Curtain
airbagsCurtain airbags help protect
the head and typically inflate
only if a severe side impact
occurs, or if the vehicle rolls
over. Curtain airbags on the
non-impacted side do not
inflate.

Tire Care and Maintenance
Maintaining Tire Pressures Keep tires inflated to the pressures shown on
the Tire and Loading Information label, even if it differs from the pressure printed on the tireitself. The Tire and Loading Information labelis located on the center door pillar and is
visible when the driver’s door is open.The Tire Pressure indicator light on
the instrument panel alerts you if
one or more tires is under- or over-
inflated.
The Tire Pressure indicator light does not
immediately turn off when you adjust tire
pressure. After inflating the tire to the
recommended pressure, you must drive over
40 km/h for more than 10 minutes to activate
the Tire Pressure Monitoring System (TPMS),
which turns off the Tire Pressure indicator
light.
If the indicator light flashes for one minute whenever you power on Model S, a fault with
the Tire Pressure Monitoring System (TPMS) is detected (see TPMS Malfunction on page
26).
Checking and Adjusting Tire Pressures
Follow these steps when tires are cold andModel S has been stationary for over three
hours:
1. Remove the valve cap.
2. Firmly press an accurate tire pressure
gauge onto the valve to measure
pressure.
3. If required, add air to reach the
recommended pressure.
4. Re-check pressure by removing and re-
attaching the tire gauge.
5. If you added too much air, release air by
pressing the metal stem in the center of
the valve.
6. Recheck the pressure with the tire gauge
and adjust if necessary.
7. Replace the valve cap to prevent dirt from
entering. Periodically check the valve for
damage and leaks.Warning: Under-inflation is the most
common cause of tire failures and can
cause a tire to overheat, resulting in
severe tire cracking, tread separation, or
blowout, which causes unexpected loss of vehicle control and increased risk ofinjury. Under-inflation also reduces
Battery range and tire tread life.Warning: Check tire pressures using an
accurate pressure gauge when tires are
cold. It takes only about 1.6 kms of driving
to warm up the tires sufficiently to affect
tire pressures. Parking the vehicle in
direct sunlight or in hot weather can also affect tire pressures. If you must checkwarm tires, expect increased pressures.Do not let air out of warm tires in an
attempt to match recommended cold tire
pressures. A hot tire at or below the
recommended cold tire inflation pressure
is dangerously under-inflated.Warning: Do not use any tire sealant
other than the type provided in a Tesla tire repair kit. Other types can cause tire
pressure sensors to malfunction. If your Model S did not include a tire repair kit,
you can purchase one from Tesla Motors.

Improving Tire Mileage
To improve the mileage you get from your
tires, maintain tires at the recommended tire pressures, observe speed limits and advisory
speeds, and avoid:
• Pulling away quickly, or hard acceleration.
• Fast turns and heavy braking.
• Potholes and objects in the road.
• Hitting curbs when parking.
• Contaminating tires with fluids that can cause damage.
Replacing Tires and Wheels
Tires degrade over time due to the effects of
ultraviolet light, extreme temperatures, high loads, and environmental conditions. It is
recommended that tires are replaced every
six years, or sooner if required.
Wheel rims and tires are matched to suit the
handling characteristics of the vehicle.
Replacement tires must comply with the
original specification. If tires other than those
specified are used, ensure that the load and
speed ratings marked on the tire equal or
exceed those of the original specification.
Ideally, you should replace all four tires at the
same time. If this is not possible, replace the
tires in pairs (both front or both rear). When
replacing tires, always re-balance and check
the alignment of wheels.
If you replace a wheel, the TPMS (Tire
Pressure Monitoring System) sensors need to
be reset to ensure they provide accurate
warnings when tires are under- or over-
inflated (see Resetting the TPMS Sensors on
page 25).Warning: For your safety, use only tires
and wheels that match the original
specification. Tires that do not match the
original specification can affect the
operation of the Tire Pressure Monitoring System (TPMS).Asymmetric Tires
Model S tires are asymmetric and must be
mounted on the wheel with the correct sidewall facing outward. The sidewall of thetire is marked with the word OUTSIDE. When
new tires are installed, make sure that the tires
are correctly mounted on the wheels.Warning: Road holding is seriously
impaired if the tires are incorrectly
installed on the wheels.
Winter Tires
In snowy and icy conditions, consider installing winter tires. Winter tires must be the
same size, brand, construction and tread
pattern on all four wheels. For
recommendations on winter tires, contact Tesla.
Warning: On dry roads, winter tires could
have less traction than the originally
installed tires.
Safety Information
24Model S Quick Guide

Using Tire ChainsTesla has tested and approved Security Chain
Company (SCC) Model Z-563 chains for use
on the rear wheels. These chains must only be
used if your Model S has 245/45R19 rear tires
installed. Do not use chains on 21 inch tires.
When installing tire chains, follow the
instructions provided by the tire chain
manufacturer. Mount them as tightly as
possible.
When using tire chains:
• Drive slowly. Do not exceed 48 km/h.
• Avoid heavily loading Model S (heavy loads can reduce the clearance betweenthe tires and the body).
• Remove the tire chains as soon as conditions allow.
Note: Tire chains are prohibited in some
jurisdictions. Check local laws before installing
tire chains.Caution: Using non-recommended tire
chains, or using tire chains on other sized tires, can damage the suspension, body,wheels, and/or brake lines. Damagecaused by using non-recommended tire
chains is not covered by the warranty.Caution: Ensure that tire chains cannot
touch suspension components or brake
lines. If you hear the chains making
unusual noises that would indicate
contact with Model S, stop and
investigate immediately.
Tire Pressure Monitoring
Each tire should be checked monthly when
cold and inflated to the recommended
pressures that are printed on the Tire and
Loading Information label located on the
driver’s door pillar (see Maintaining Tire Pressures on page 22). If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire inflation pressure
label, determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring system (TPMS) that displays a tire pressuretelltale (Tire Pressure Warning) on the
instrument panel when one or more of your
tires is significantly under- or over-inflated.
Accordingly, when the Tire Pressure indicator
light displays on the instrument panel alerting
of tire pressure, stop and check your tires as
soon as possible, and inflate them to the proper pressure (see Maintaining TirePressures on page 22). Driving on a
significantly under-inflated tire causes the tire
to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's
handling and stopping ability.If Model S detects a fault with the
Tire Pressure Monitoring System
(TPMS), this indicator flashes for one
minute whenever you power on
Model S.
Note: Installing accessories that are not
approved by Tesla can interfere with the TPMS system.
Warning: The TPMS is not a substitute for
proper tire maintenance, including
manually checking tire pressures and
regularly inspecting the condition of tires.
It is the driver's responsibility to maintain
correct tire pressure, even if under- or
over-inflation has not reached the level
for the TPMS to trigger the Tire Pressure Warning on the instrument panel.
Resetting the TPMS Sensors
After replacing one or more wheels, the TPMS sensors must be reset to ensure tire pressurewarnings are accurate. However, note that theTPMS sensors do not need to be reset after
replacing a tire or rotating wheels.
Note: When changing to 21" wheels
(Performance Plus models), the TPMS may
generate false tire pressure warnings. Bring
Model S to a Tesla Service center for further
adjustment.
Note: Do not reset the TPMS sensors in an
attempt to clear tire pressure warnings.
Safety Information
Safety Information25

To reset TPMS sensors:
1. Inflate all tires to their recommend
pressures, as indicated on the Tire and
Loading Information label located on the
driver’s door pillar.
2. Get ready to drive for ten minutes, then,
on the Model S touchscreen, touch
Controls > Settings > Vehicle > Tire
Pressure Monitor > Reset Sensors .
3. Follow the onscreen instructions.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays
frequently, contact Tesla to determine if a tire
sensor needs to be replaced. Tire sensors
must be replaced by a Tesla service technician
who can perform a brief setup procedure. If a
non-Tesla service center repairs or replaces a
tire, the tire sensor will not work until Tesla
performs the setup procedure.
TPMS Malfunction
Model S 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 tire pressure
indicator light. When the system
detects a malfunction, the indicator
flashes for approximately one
minute after Model S powers on, and
then remains continuously lit. This
sequence continues upon
subsequent vehicle start-ups as long
as the malfunction exists. When the
TPMS malfunction indicator is on,
the system might not be able to
detect or signal under- and over-
inflated tires as intended.
TPMS malfunctions can occur for a variety of
reasons, including installing replacement oralternate tires or wheels on the vehicle thatprevent 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: If a tire has been replaced or repaired
using a different tire sealant than the one
available from Tesla, and a low tire pressure is
detected, it is possible that the tire sensor has
been damaged. Contact Tesla to have the
fault repaired as soon as possible.
