Speed Assist
How Speed Assist Works
When the Speed Limit Warning is turned on,
the touchscreen displays a speed limit as determined by GPS data. You can touch this
speed limit sign to automatically change the
set speed to the detected speed limit
(including any offsets that you have set).
Warnings (described later) take effect when
you exceed this limit.
In situations where Speed Assist is unable to
determine a speed limit (for example, speed
limit signs and GPS data are not available at the current location), or if Speed Assist is
uncertain that an acquired speed limit is
accurate (for example, although a speed limit sign was initially detected, some time has
passed before a subsequent sign has been
detected), the touchscreen may not display a
speed limit sign and warnings do not take effect.
If you set the speed limit warning to Display
(see Controlling Speed Assist on page 92)
and exceed the determined speed limit, the
speed limit sign on the touchscreen increases
in size.
If you set the speed limit warning to Chime
(see Controlling Speed Assist on page 92)
and exceed the determined speed limit, the
speed limit sign on the touchscreen increases
in size and Model 3 also sounds a warning
chime.
Note: Speed limit warnings go away after ten
seconds, or when Model 3 slows down below
the specified limit.
Warning:
Do not rely on Speed Assist to
determine the appropriate speed limit ordriving speed. Always drive at a safe
speed based on traffic and road
conditions.
Controlling Speed Assist
To adjust the Speed Limit Warning setting,
touch Controls > Autopilot > Speed Limit
Warning , then choose one of these options:

Driving in Low 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
(kilometers) until the tires warm up.
Using Tire Chains
Tesla has tested and approved the following tire chains to increase traction in snowy
conditions. Tire chains should only be installed
on the rear tires.Tire SizeRecommended
Chain18"PEWAG SERVO
SPORT RSS 7619"PEWAG SERVO RS
7720"MAGGI TRAK SP214Caution: If your Model 3 is equipped with
aero covers, you must remove them before installing tire chains (see Removing and Installing Aero Covers on
page 133). Failure to do so can cause
damage not covered by the warranty.
When installing tire chains, follow the
instructions provided by the tire chain
manufacturer. Mount them as tightly as possible.
