To ensure that Model S provides you with the best
ownership experience possible in harsh cold weather
conditions, follow these best practices.
Before Driving
When snow and ice accumulate on your vehicle, moving
parts, such as the door handles, windows, mirrors, and
wipers can freeze in place. For these reasons, and to
achieve maximum range and performance, it is helpful to
warm the cabin and Battery before you leave. There are
several ways to do so:
• Scheduled Departure: Set the time when you want
your vehicle to be ready to drive (see
Scheduled
Charging and Scheduled Departure on page 159).
•
On the mobile app, navigate to Climate > Turn On
Climate and set to HI (or customize the temperature
at which you want to heat the cabin). The Battery
also warms as needed.
•
On the mobile app, navigate to Climate > Defrost to
melt snow, ice, and frost on the windshield, driver and
passenger windows, mirrors. The Battery also warms
as needed.
NOTE: Tesla recommends activating climate settings
at least 30-45 minutes before departure (see
Climate
Controls on page 124). Preconditioning times
depend on outside temperature and other factors.
NOTE: In extremely cold weather or icy conditions, it is
possible that your charge port latch may freeze in place.
In cases where you cannot remove or insert the charge
cable, or the vehicle is not Supercharging due to the
latch being frozen in place, use your Tesla mobile app to
precondition your vehicle on
HI for approximately 30-45
minutes (you must use your mobile app to precondition
the vehicle; setting your climate to HI using the
touchscreen will not be eective). This can help thaw ice
on the charge port latch so the charge cable can be
removed or inserted.
NOTE: Tesla recommends activating climate settings at
least 30-45 minutes before departure (see Climate
Controls on page 124). Preconditioning times depend
on outside temperature and other factors.
Windows
•
On the mobile app, navigate to Climate > Defrost as
mentioned previously.
• Use the mobile app to schedule a service
appointment for Tesla to provide hydrophobic
coating to your windows for a nominal fee.
Mirrors
If ice buildup is expected when parking, turn o Auto-
Fold Mirrors by navigating to Controls > Vehicle > Mirror
Auto-Fold > ON. Ice can prevent exterior side mirrors
from folding or unfolding.
NOTE:
Side mirrors automatically heat as needed during
preconditioning, or when the rear defroster is turned on.
Wipers
If you expect snow or ice to build up when parked,
navigate to
Controls > Service > Wiper Service Mode >
ON. This raises wipers against the windshield so they
can defrost when the windshield defrosts (see Wipers
and Washers on page 58).
Winter Tires and Tire Chains
•
Use winter tires to increase traction in snowy or icy
conditions. You can purchase winter tires on
http://
www.tesla.com (see Seasonal Tire Types on page
166).
• Tire chains provide additional traction when driving in
snowy or icy conditions. Check local regulations to
determine if tire chains are recommended or required
during winter months. See
Using Tire Chains on page
166 for more information.
While Driving
Cold weather can increase energy consumption because
more power is required for driving, cabin and Battery
heating. Follow these suggestions to reduce energy
consumption:
•
Use seat heaters to keep warm. Seat heaters use less
energy than the cabin heater. Lowering the cabin
temperature and using seat heaters will reduce
energy consumption (see Climate Controls on page
124).
•
Slow down your driving and avoid frequent and rapid
acceleration.
•
Turn on Range Mode (if equipped) to automatically
limit the power that the climate control system uses
to maintain the temperature of the Battery and the
cabin area. Range Mode also turns
o signature lights
(if equipped) and adjusts the front and rear motor
torque split to maximize range (see Getting Maximum
Range on page 70).
Regenerative Braking
Regenerative braking can be limited if the Battery is too
cold. As you continue to drive, the Battery warms up
and regenerative power increases (see Regenerative
Braking on page 60).
NOTE: Limited regenerative braking can be avoided if
you allow enough time to precondition your vehicle or
use scheduled departure before your drive, as
mentioned previously.
