2015 TESLA MODEL S brakes

Hill Start Assist automatically engages the
brakes for approximately one second when on
a hill. This prevents Model S from rolling
during the time it takes for you to move your
foot from the brake pedal to the accelerator
pedal. Hill Start Assist engages the brakes
only if Model S is in Drive and facing uphill, or
in Reverse and facing downhill.Warning: After approximately one
second, Hill Start Assist no longer brakes
your vehicle and it could roll. Therefore,
quickly move your foot from the brake
pedal to the accelerator pedal. Never rely on Hill Start Assist to prevent Model Sfrom rolling for more than one second.Failure to do so can result in a collision.

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 20).
• 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 109).
• Check washer fluid level and top up if necessary (see Topping Up Washer Fluid
on page 125).
• Check that the air conditioning system is operating (see Climate Controls on page
80).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
108Model S Owner's Manual

Checking Brake FluidWarning: Contact Tesla immediately if
you notice increased movement of the
brake pedal or a significant loss of brake
fluid. Driving under these conditions can result in extended stopping distances orcomplete brake failure.The Brake indicator on the
instrument panel alerts you if the
quantity of fluid in the brake
reservoir drops below the
recommended level. If it displays
while driving, stop as soon as safety
permits by gently applying the
brakes. Do not continue driving.
Contact Tesla immediately.
Fluid Level Check
Tesla checks the brake fluid level at the
regularly scheduled maintenance intervals. To check it yourself, park Model S on level
ground. When Model S is cool, remove the maintenance panel (see Removing the
Maintenance Panel on page 123).
Check the fluid level visually by looking at the
outside marks on the side of the reservoir
without removing the filler cap.
The brake fluid level should always be
between the MIN and the MAX marks.
Note: Although brake fluid level drops slightly
during normal use as a result of brake pad wear, it should not drop below the MIN mark.
Topping Up the Brake Fluid
Do not top up your brake fluid. Tesla service does this when you bring Model S in for
regular servicing. The following instructions are provided for information purposes andfuture reference only:
1. Clean the filler cap before removing to
prevent dirt from entering the reservoir.
2. Unscrew the cap and remove.
3. Top up the reservoir to the MAX mark
using brake fluid meeting DOT3 or DOT4 specifications.
4. Replace the filler cap.Warning: Only use new fluid from a
sealed air-tight container. Never use previously used fluid or fluid from apreviously opened container—fluid
absorbs moisture which decreases
braking performance.Warning: Brake fluid is highly toxic. Keep
containers sealed and out of the reach of children. In the event of accidentalconsumption, seek medical attention
immediately.Caution: Brake fluid damages painted
surfaces. Immediately soak up any spills
with an absorbent cloth and wash the
area with a mixture of car shampoo and
water.
