Exterior Overview
Overview3

Driving Tips to Maximize RangeYou can maximize your driving range usingthe same driving habits that you use to
conserve fuel in a gasoline-powered vehicle. In
addition to driving habits, energy
consumption depends on environmental conditions (such as cold weather and hillyroads). To get the maximum mileage from a
charge:
• Avoid frequent and rapid acceleration. • Instead of using the brake to slow down, move your foot off the accelerator.
Whenever Model S is moving and your
foot is off the accelerator, regenerative
braking slows down Model S and feeds
surplus energy back to the Battery (see
Regenerative Braking on page 59).
• Keep tires at the recommended inflation pressures (see Tire Care and Maintenance
on page 100).
• Lighten your load by removing any unnecessary cargo.
• Limit the use of resources such as heating and air conditioning. Using seat heaters to
keep warm is more efficient than heating the cabin. You can turn on Range mode toautomatically limit the power of theclimate control system (see Settings on
page 69).
The power meter on the instrument panel and
the Energy app provide feedback on energy
usage. With this feedback, you will soon become familiar with how driving habits andenvironmental conditions impact how muchenergy Model S is using.
Saving Energy
Model S has an energy-saving feature that
reduces the amount of energy being consumed when Model S is not in use. TouchControls > Displays > Energy Saving and
choose from the following options:
• OFF . All display systems remain powered
when Model S is not in use, providing the
most responsive experience. More energy
is consumed.
• NIGHTLY . Model S shifts to the energy-
saving mode at night (10 pm to 5 am).
• ON. Significantly less energy is consumed
whenever Model S is not in use. The start-
up time of the instrument panel and
Bluetooth could be slower.
• Always Connected . Preserves cell
connectivity when energy saving is active.
This allows the mobile app to connect toModel S more quickly, and provides
immediate 3G internet access when entering the car. Slightly more energy isconsumed.
Getting Maximum Range
Driving57

Braking SystemsModel S has an anti-lock braking system
(ABS) that prevents the wheels from locking
when you apply maximum brake pressure. This improves steering control during heavy
braking in most road conditions.
During emergency braking conditions, the
ABS constantly monitors the speed of each
wheel and varies the brake pressure according
to the grip available.
The alteration of brake pressure can be felt as
a pulsing sensation through the brake pedal.
This demonstrates that the ABS is operating
and is not a cause for concern. Keep firm and
steady pressure on the brake pedal while
experiencing the pulsing.The ABS indicator flashes briefly on
the instrument panel when you first
start Model S. If this indicator lights
up at any other time, an ABS fault
has occurred and the ABS is not
operating. Contact Tesla. The
braking system remains fully
operational and is not affected by an
ABS failure. However, braking
distances may increase.If the instrument panel displays this
indicator at any time other than
displaying briefly when you first start
Model S, a brake system fault is
detected or the brake fluid level is
low. Contact Tesla immediately.Emergency Braking
In an emergency, fully press the brake pedal
and maintain firm pressure, even on low
traction surfaces. The ABS varies the braking pressure to each wheel according to the
amount of traction available. This prevents wheels from locking and ensures that you
stop as safely as possible.Warning: Do not pump the brake pedal.
Doing so interrupts operation of the ABS
and can increase braking distance.Warning: Always maintain a safe distance
from the vehicle in front of you and be aware of hazardous driving conditions.
While the ABS can improve stopping
distance, it cannot overcome the laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of
water prevents direct contact between
the tires and the road).
Brake Wear
Model S brake pads are equipped with wearindicators. A wear indicator is a thin metalstrip attached to the brake pad that squeals as
it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their
service life and require replacement. To stop
the squealing, contact Tesla Service.
Warning: Neglecting to replace worn
brake pads results in damage to the
braking system and can create a braking
hazard.
Brakes
58Model S Owner's Manual

Service Intervals
Regular maintenance is the key to ensuring
the continued reliability and efficiency of your
Model S.
Rotate the tires every 5000 miles (8000 km),
maintain the correct tire pressures, and take Model S to Tesla at the regularly scheduledmaintenance intervals of every 12 months, orevery 12,500 miles (20,000 km), whichever
comes first. It is also important to perform the
daily and monthly checks described below.
Model S must be serviced by Tesla-certified
technicians. Damages or failures caused by
maintenance or repairs performed by non-
Tesla certified technicians are not covered by
the warranty.
Daily Checks • Check the Battery’s charge level, displayed on the instrument panel.
• Check that all exterior lights, horn, turn signals, and wipers and washers are
working.
• Check the operation of the brakes, including the parking brake.
• Check the operation of the seat belts (see Seat Belts on page 19).
• Look for fluid deposits underneath Model S that might indicate a leak. It is
normal for a small pool of water to form
(caused by the air conditioning system’s dehumidifying process).
Monthly Checks • Check the mileage to determine if the tires need to be rotated (every
5000 miles/8000 km), and check the
condition and pressure of each tire (see
Tire Care and Maintenance on page 100).
• Check washer fluid level and top up if necessary (see Topping Up Washer Fluid
on page 116).
• Check that the air conditioning system is operating (see Climate Controls on page
72).Warning: Contact Tesla immediately if
you notice any significant or sudden drop in fluid levels or uneven tire wear.Fluid Replacement Intervals
Do not change or top up Battery coolant and
brake fluid yourself. Tesla service technicians replace fluids at the regularly scheduled
service intervals:
• Brake fluid. Every 2 years or 25,000 miles (40,000 km), whichever comes first.
• Battery coolant. Every 5 years or 62,500 miles (100,000 km), whichever
comes first.
Note: Any damage from opening the Battery
coolant reservoir is excluded from the warranty.
High Voltage Safety Your Model S has been designed and built
with safety as a priority. However, be aware of these precautions to protect yourself from the
risk of injury inherent in all high-voltage
systems:
• Read and follow all instructions provided on the labels that are attached to Model S.These labels are there for your safety.
• The high voltage system has no user- serviceable parts. Do not disassemble,
remove or replace high voltage components, cables or connectors. High
voltage cables are colored orange for
easy identification.
• If an accident occurs, do not touch any high voltage wiring, connectors, or
components connected to the wiring.
• In the unlikely event that a fire occurs, immediately contact your local fire
emergency responders.Warning: Always disconnect the charge
cable before working underneath Model S, even if charging is not in
progress.Warning: Keep your hands and clothing
away from cooling fans. Some fans
operate even when Model S is powered
off.Caution: Some fluids (battery acid,
Battery coolant, brake fluid, windshield
washer additives, etc.) used in motor
vehicles are poisonous and should not be
inhaled, swallowed, or brought into contact with open wounds. For your
safety, always read and follow
instructions printed on fluid containers.
Maintenance Schedule
Maintenance99

Maintaining Tire PressuresKeep tires inflated to the pressures shown onthe Tire and Loading Information label, even ifit differs from the pressure printed on the tire
itself. The Tire and Loading Information label is located on the center door pillar and isvisible 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
25 mph (40 km/h) for more than 10 minutes to activate the Tire Pressure MonitoringSystem (TPMS), which turns off the TirePressure 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
104).
Checking and Adjusting Tire Pressures
Follow these steps when tires are cold and
Model 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 one mile (1.6 km) 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 check warm tires, expectincreased 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 coldtire 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.
Tire Care and Maintenance
100Model S Owner's Manual

Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for
any sign of distortion (bulges), cuts or wear.Warning: Do not drive Model S if a tire is
damaged, excessively worn, or inflated to
an incorrect pressure. Check tires
regularly for wear, and ensure there are
no cuts, bulges or exposure of the ply/
cord structure.
Tire Wear
Model S is originally fitted with tires that have wear indicators molded into the tread pattern.
When the tread has been worn down to 1/16” (1.6 mm), the indicators start to appear at the
surface of the tread pattern, producing the effect of a continuous band of rubber across
the width of the tire.
Replace a tire as soon as an indicator band becomes visible or the tread depth reachesthe minimum permitted by law.
Tire Rotation, Balance, and Wheel Alignment
Tesla recommends rotating the tires every
5000 miles (8000 km).
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel) affect
vehicle handling and tire life. Even with
regular use, wheels can get out of balance.
Therefore, they should be balanced as
required.
If tire wear is uneven (on one side of the tire
only) or becomes abnormally excessive, check
the alignment of wheels.
Note: When replacing only two tires, always
install the new tires on the rear.
Punctured Tires
A puncture eventually causes the tire to lose
pressure, which is why it is important to check
tire pressures frequently. Permanently repair
or replace punctured or damaged tires as
soon as possible. Do not drive with a
punctured tire, even if the puncture has not
caused the tire to deflate. A punctured tire
can deflate suddenly at any time.
Your tubeless tires may not leak when
penetrated, provided the object remains in the
tire. If, however, you feel a sudden vibration or
ride disturbance while driving, or you suspect
a tire is damaged, immediately reduce your
speed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do
so, stop the vehicle. Arrange to have Model S
transported to a Tesla service center, or to a
nearby tire repair center.
Note: In some cases, you can temporarily
repair small tire punctures (under 1/4”/6 mm)
using an optional tire repair kit available from
Tesla. This allows you to slowly drive Model S to Tesla or to a nearby tire repair facility.Warning: Do not drive Model S with a
punctured tire. Even if the punctured tire has not deflated, it can suddenly deflate
at any time.
Flat Spots
If Model S is stationary for a long period in
high temperatures, tires can form flat spots. When Model S is driven, these flat spots causea vibration which gradually disappears as thetires warm up and regain their original shape.
To minimize the flat spots during storage,
inflate tires to the maximum pressure
indicated on the tire wall. Then, before driving, release air to adjust tire pressure to the
recommended levels.
Driving in Low Ambient Temperatures
Tire performance is reduced in low ambient temperatures, resulting in reduced grip and an
increased susceptibility to damage from
impacts. Performance tires can temporarily
harden when cold, causing you to hear
rotational noise for the first few miles (kms)
until the tires warm up. Contact Tesla for
winter tire recommendations.
Tire Care and Maintenance
Maintenance101

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 103).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.
Tire Care and Maintenance
102Model S Owner's Manual

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 tiresinstalled. Do not use chains on 21 inch tires.
When installing tire chains, follow the instructions provided by the tire chainmanufacturer. Mount them as tightly as
possible.
When using tire chains:
• Drive slowly. Do not exceed 30 mph (48 km/h).
• Avoid heavily loading Model S (heavy loads can reduce the clearance between
the 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 100). 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 pressure
telltale (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 Tire
Pressures on page 100). 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.
Tire Care and Maintenance
Maintenance103

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.
