Interior temperature control7-4
Comfort and convenience
Interior temperature controlGeneral informationThe temperature of the air inside the vehicle
is controlled using the controls on the center
console.
Heating is provided by a high voltage electric
heater located under the hood. Cooling is
provided by an all-electric air conditioning
system located under the hood. In addition to
cooling the cabin, the system also cools the
Battery.
Note: In high ambient temperatures, the
system may not be able to achieve the
desired cabin temperature. This is normal,
with priority being given to cooling the
Battery to ensure that cell temperatures stay
within a range that supports long life and
efficient performance.Control panel1. Driver’s seat heater

The heating and air conditioning in your Tesla
Roadster operate differently from those in
conventional vehicles in two key ways. First,
the temperature control 3 doesn’t do
anything unless either the air conditioning 4
or the heating system 5 button is pressed.
Second, because the vehicle is designed to
conserve the Battery’s energy, the air conditioning system and the heating system
must be manually turned on each time you
start the vehicle—even if they were turned on
when you shut the vehicle off.
Also note that if both the air conditioning and
heating is turned on at the same time, you get
a nominal amount of cooling. If operating
when the ambient temperature is below 2°, it
is recommended you press the air
recirculation
7 button.
Operating the systemNote: The fan, heating and air conditioning
system are powered by the Battery.
Prolonged use decreases the range of the
vehicle.
Heating and air conditioning must be
reselected each time the starter switch is
turned to the ON position or whenever the
fan is turned off.Fan speedRotate the fan control 6 clockwise to increase
fan speed.
With the fan switched off, the amount of air
entering the vehicle depends on your driving
speed. To operate the air conditioning or
heating systems, the fan must be turned on.Te m p e r a t u r eRotate the temperature control 3 clockwise
or counterclockwise to adjust the
temperature of the heated or cooled air.
Unlike the temperature control system of a
conventional vehicle, the temperature of the
air entering the vehicle will change only if the
heating or air conditioning system is
operating.Air conditioningEnsure that the fan 6 is on, then press button
4 to operate the air conditioning system. The
indicator in the switch illuminates blue when
the system is operating. Press again to switch
off.

Interior temperature control
7-5
Comfort and convenience
Rotate the temperature control to achieve
the desired air temperature.
Note: In high ambient temperatures, cooling
may be temporarily diverted away from the
passenger compartment to cool the Battery.HeatingEnsure that the fan 6 is on, then press button
5 to operate the heating system. The
indicator in the switch will illuminate amber
when the system is operating. Press again to
switch off.
Rotate the temperature control to achieve
the desired air temperature.Air recirculationPress button 7 to operate air recirculation.
The indicator in the switch will illuminate
green. Press again to switch off.
When air recirculation is operating, and the
soft-top or hard-top is installed, 90% of the
air from within the passenger compartment is
recirculated, instead of being drawn from
outside the vehicle. This is useful for
preventing fumes from entering the vehicle
or to effectively maintain a constant
temperature.
Note: It is recommended that recirculation is
switched off for a short period each hour to
refresh the air inside the vehicle, and to help
prevent the windshield from fogging.Air distributionRotate the air distribution control 8 to
change the points at which air enters the
passenger compartment. Windshield vents
Footwell vents
Face vents
Air flow from the vents can be mixed by
positioning the control between the
distribution settings.
Ve n t i l a t i o nAir is drawn into the ventilation system
through the grill at the front of the vehicle.
Keep the grill clear of obstructions (leaves,
snow, etc.).
Press the thumb depression to open the
vents and rotate to direct the air. The vents
on each side of the dashboard can be
adjusted to direct air onto the side windows.
Note: With the face level vents open, airflow
to the foot and windshield outlets is reduced. TR0026
Windshield defrostingFor maximum efficiency when removing frost
or mist from your windshield, set the controls
as follows:
1. Rotate the air distribution control to windshield.
2. Rotate the fan control fully clockwise.TR0027

Fluid reservoirs
9-5
Maintenance and care
Windshield washer fluidTo ensure proper cleaning of the windshield
and to prevent freezing in cold weather check
the reservoir level weekly. If needed, top up
with windshield washer fluid.
Caution: Always follow the directions
provided by the windshield washer fluid
manufacturer. If the windshield washer fluid
requires dilution, carefully follow the
manufacturer’s directions and mix the
recommended quantities of water and
windshield washer fluid in a separate
container before topping up the reservoir.
Undiluted windshield washer fluid can cause
paint to discolor.
Battery coolantFluid level checkCheck the fluid level weekly with the vehicle
on level ground and when the vehicle is cool.
The fluid level can be checked visually
through the side of the reservoir without
removing the filler cap. The fluid level should
be between the MIN and the MAX marks.
If the level drops significantly, a leak may
exist. Contact Tesla Motors before using the
vehicle.
To p p i n g u p t h e c o o l a n t
The cooling system for your vehicle
contains a propylene glycol (PG) based
antifreeze. Compared to conventional
ethylene glycol based antifreezes, propylene
glycol is less toxic, sa fer for children, pets and
wildlife, and safer for the environment.
Top-up to the MAX mark with a 50% mix of
water and Havoline
® Extended Life antifreeze
Coolant-PG (Havoline XLC-PG).
Caution: Do not mix with any other type
of antifreeze! In an emergency, top up
with distilled water only and be aware of the
reduced frost and corrosion protection.
Antifreeze contains important corrosion
inhibitors. Maintain the antifreeze content of
the coolant between 50% and 60% year
round. Do not exceed 60% or cooling
efficiency will be impaired.
Ensure cap is replaced and fully tightened
after topping up.
Note: Change coolant every four years,
regardless of mileage.

Cleaning and vehicle care9-8
Maintenance and care
WheelsWash wheels with warm, fresh water
containing a good quality wash and wax
shampoo. Thoroughly rinse the wheels to
remove any soap residue.Windshield, windows and mirrorsRegularly clean all windows inside and out
using a window cleaning solution. An
automotive glass cleaner is recommended.
After washing the vehicle with wash/wax
products, clean the outside of the windshield
with glass cleaner.
Mirror glass is particularly susceptible to
damage. Do not use abrasive cleaning
compounds.Wiper bladesClean wiper blades using mild soap and warm
water only. Do not use petroleum or
alcohol-based cleaners.
Polishing the bodyTo preserve the cosmetic appearance of the
body, occasionally apply a good quality
polish. A good polish should contain a very
mild abrasive that removes surface
contamination without damaging the
surface, a mild filling compound to reduce the
appearance of scratches, and wax to provide
a barrier between the cleaned body surface
and airborne contaminants.
Do not use cutting paste, color restoration
compounds, or polishes containing a harsh
abrasive. These can scour the surface and
permanently degrade the body.Using a car coverTo preserve the cosmetic appearance of the
body, you may want to use a car cover. Only
an approved Tesla Motors car cover should be
used. DONOT use the car cover when
charging the vehicle. Doing so can interfere
with adequate cooling during charging.Paint damage and rectificationTreat chips and scratches to the paint using a
paint touch-up pen. Use the touch-up pen
after washing but before polishing or waxing.
More extensive repairs to the body should
only be carried out by a facility approved by
Tesla Motors. Contact Tesla Motors for a list of
approved body repair facilities.
Cleaning the vehicle interiorPlastic materials
Caution: Do not polish the upper
surfaces of the dashboard. Polished
surfaces are reflective and may interfere with
the driver's view.
Clean with diluted upholstery cleaner, then
wipe with a damp cloth.
Carpet and fabricsClean with diluted upholstery cleaner. Test a
concealed area first.LeatherClean with warm water and a non-detergent
soap. Dry and polish with a dry, clean,
lint-free cloth.Seat beltsExtend the belts and clean with warm, soapy,
fresh water only. Do not use any type of
detergent or chemical cleaning agent. Allow
the belts to dry naturally while extended,
preferably away from direct sunlight.Instruments and display screensClean the instrument panel, Touch Screen,
