How It Works
The traction control system constantly monitors the speed of the front and rear wheels. If
Model S
experiences a loss of traction, the system minimizes wheel spin by controlling brake pressure and motor power. By default, the traction control system is on. Under normal conditions, it should remain on to ensure
maximum safety.
This yellow indicator flashes on the
instrument panel whenever the traction
control system is actively controlling brake
pressure and motor power to minimize wheel spin. If the indicator stays on, a fault is detected with the traction control system. Contact Tesla Service.
WARNING: Traction control cannot prevent
collisions caused by driving dangerously or turning
too sharply at high speeds.
Allowing Wheel Slip
To allow the wheels to spin at a limited speed, you can
enable Slip Start.
Slip Start can be enabled only when
Model S is moving 30 mph (48 km/h) or slower. Slip
Start automatically disables when the speed exceeds
50 mph (80 km/h).
Under normal conditions, Slip Start should not be enabled. Enable it only in circumstances where you
deliberately want the wheels to spin, such as:
When Model S is stopped, Vehicle Hold can continue to
apply the brakes even after you remove your foot from
the brake pedal.
When the vehicle
4. To change your speed while using Traffic-Aware
Cruise Control, you can roll the right scroll wheel on
the steering wheel up or down. For more details, see
Changing the Cruising Speed on page 85.

To cancel Traffic-Aware Cruise Control, press the right
scroll wheel, or press the brake pedal. See
Canceling
and Resuming on page 87 for more information.
Set Traffic-Aware Cruise Control
Chime
If you want a chime to sound when you engage or cancel
Traffic-Aware Cruise Control, touch Controls >
Autopilot > Traffic-Aware Cruise Control Chime.
NOTE: Model S must be in Park.
Changing the Cruising Speed
Roll the right scroll wheel up to increase, or down to decrease, the set speed. Slowly rolling the scroll wheel
changes the set speed in
1 mph (1 km/h) increments and
quickly rolling the scroll wheel changes the set speed to the closest
5 mph (5 km/h) increment. For example, if
you are traveling at
57 mph and quickly roll the scroll
wheel, the speed increases to
60 mph.
NOTE: It may take a few seconds for Model S to reach
the new cruising speed, assuming
Model S is not cruising
behind a vehicle that is driving slower than your set
speed.
Cruising at the Set Speed
Traffic-Aware Cruise Control maintains your set cruising
speed whenever a vehicle is not detected in front of
Model S. When cruising behind a detected vehicle,
Traffic-Aware Cruise Control accelerates and decelerates
Model S as needed to maintain a chosen following
distance (see
Adjust the Following Distance on page
86), up to the set speed.
Traffic-Aware Cruise Control also adjusts the cruising
speed when entering and exiting curves.
You can manually accelerate at any time when cruising
at a set speed, but when you release the accelerator,
Traffic-Aware Cruise Control resumes cruising at the set
speed.
NOTE: When Traffic-Aware Cruise Control is actively
slowing down
Model S to maintain the selected distance
from the vehicle ahead, brake lights turn on to alert other road users that you are slowing down. You may
notice slight movement of the brake pedal. However,
when
Traffic-Aware Cruise Control is accelerating
Model S, the accelerator pedal does not move.
WARNING: Traffic-Aware Cruise Control may
occasionally cause Model S to brake when not
required or when you are not expecting it. This can
be caused by closely following a vehicle ahead,
detecting vehicles or objects in adjacent lanes
(especially on curves), etc.
WARNING: Due to limitations inherent in the
onboard GPS (Global Positioning System), you
may experience situations in which Model S slows
down, especially near exits or off-ramps where a
curve is detected and/or you are navigating to a
destination and not following the route.
WARNING: Traffic-Aware Cruise Control may not
detect all objects and, especially when cruising
over 50 mph (80 km/h), may not brake/decelerate
when a vehicle or object is only partially in the
driving lane or when a vehicle you are following
moves out of your driving path and a stationary or
slow-moving vehicle or object is in front of you.
Always pay attention to the road ahead and stay
prepared to take immediate corrective action.
Depending on Traffic-Aware Cruise Control to
avoid a collision can result in serious injury or
death. In addition, Traffic-Aware Cruise Control
may react to vehicles or objects that either do not
exist, or are not in your lane of travel, causing
Model S to slow down unnecessarily or
inappropriately.
WARNING: Traffic-Aware Cruise Control may be
unable to provide adequate speed control because
of limited braking capability and hills. It can also
misjudge the distance from a vehicle ahead.
Driving downhill can increase driving speed,
causing Model S to exceed your set speed (and
potentially the road
When an automatic lane change is in progress, Overtake Acceleration is activated, allowing
Model S to accelerate
closer to a vehicle in front (see
Overtake Acceleration on
page 86).
NOTE: Auto Lane Change moves Model S one lane at a
time. Moving into an additional lane requires you to
engage the turn signal a second time after the
first lane
change is complete.
When using Auto Lane Change, it is important to monitor its performance by watching the driving path in front of you and the surrounding area. Stay prepared to take over steering at any time. As you are crossing over into the adjacent lane, the
instrument panel displays the
location in the lane that
Model S is moving into.
In situations where Auto Lane Change is unable to operate at optimal performance, or cannot operate due to inadequate data, the
instrument panel displays a
series of warnings. Therefore, when using Auto Lane Change, always pay attention to the
instrument panel
and be prepared to manually steer Model S.
Adjacent Lane Speed
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Adjacent Lane
Speed, or the feature may not operate exactly as
described.
When moving significantly faster than vehicles in
adjacent lanes,
Model S automatically reduces the
driving speed. This is especially helpful in heavy
traffic
situations or when vehicles are constantly merging into
different lanes. When Model S detects other vehicles
driving
significantly slower, the instrument panel
highlights the adjacent lanes with arrows and detected
vehicles in gray, and
Model S reduces the driving speed
as appropriate. To temporarily override this feature, press the accelerator pedal.
WARNING: Never depend on Autopilot to
determine a safe driving speed; you are
responsible for driving safely and according to
traffic laws in your market region.
Stop Light and Stop Sign Warning
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Stop Light and
Stop Sign Warning, or the feature may not operate
exactly as described.
While Autosteer is in use, Model S displays a warning on
the
instrument panel and sounds a chime if it detects
that you are likely to run through a red stop light or stop sign. If this happens,
TAKE IMMEDIATE CORRECTIVE
ACTION!
The visual and audible warnings cancel after a few
seconds, or when you press the brake pedal, whichever
comes
first.
Stop Light and Stop Sign Warning provides warnings
only. It does not slow down or stop
Model S at red traffic
lights, stop signs, road markings, etc. If equipped with
Traffic Light and Stop Sign Control, you can enable this
feature to automatically stop Model S at traffic lights
and stop signs (see Traffic Light and Stop Sign Control
on page 96).
CAUTION: Stop Light and Stop Sign Warning
requires on-board maps to know that a particular
stop light or stop sign exists at a location. In some
cases, map data is inaccurate or outdated and may
not include all stop lights or stop signs. Therefore,
Stop Light and Stop Sign Warning may not detect
all stop lights and stop signs.
WARNING: The Stop Light and Stop Sign Warning
feature does not apply the brakes or decelerate
Model S and may not detect all stop lights and
stop signs. Stop Light and Stop Sign Warning is
designed for guidance purposes only and is not a
substitute for attentive driving and sound
judgment. Keep your eyes on the road when
driving and never depend on Stop Light and Stop
Sign Warning to warn you of a stop light or stop
sign.
WARNING: Stop Light and Stop Sign Warning is
designed to warn you only when approaching a
visible red stop sign, solid red or later portion of a
yellow traffic light. It may not warn you of
intersections with flashing lights and it does not
warn you of yield signs or temporary stop and
yield signs (such as those used in construction
areas). Additionally, Stop Light and Stop Sign
Warning does not warn you of approaching stop
lights or stop signs when you are pressing the
accelerator pedal or brake pedal (which disables
Autosteer).
Limitations
Autosteer and its associated functions are particularly
unlikely to operate as intended when:
To Pause Parking
To pause Autopark, press the brake pedal once. Model S
stops and remains stopped until you touch Resume on
the touchscreen.
To Cancel Parking
Autopark cancels the parking sequence when you
manually move the
steering yoke (or steering wheel),
shift, or touch
Cancel on the touchscreen. Autopark also
cancels parking when:
WARNING: Forward Collision Warning does not
provide a warning when the driver is already
applying the brake.
Automatic Emergency Braking
Model S is designed to determine the distance from a
detected object traveling in front of it. When a frontal collision is considered unavoidable, Automatic Emergency Braking is designed to apply the brakes to
reduce the vehicle
Real-time Visualization
The image of your Model S on the Suspension screen
provides a real-time visualization of the status of the air suspension system. In addition to visually showing changes to the ride height, it displays Compression and Rebound lines that
reflect how the suspension system is
controlling the dampers for each wheel based on your
chosen settings and changing road conditions. Both are controlled simultaneously. Touch
Show Suspension Data
to display detailed information about the dampers for
each wheel, including ride height, compression and
rebound values, and body accelerations.
Auto-Raising Locations
Whenever you raise the suspension to High or Very
High, the location is automatically saved. By saving the
location, you do not need to manually raise the
suspension every time you arrive at a frequently-used location where you have previously raised the
suspension. When you return to the saved location,
Model S raises the suspension and the instrument panel
displays a message indicating that the suspension is being raised.
When saving locations, Model S also saves the Keep until
XX mph setting (if specified).
NOTE: When returning to a saved location and driving
faster than the
High and Very High suspension settings
allow, the suspension does not raise until
Model S slows
down.
NOTE: After leaving a saved location, the suspension
automatically lowers. However, it may not lower until
Model S meets the speed and distance threshold at
which the suspension lowers.
NOTE: If Model S reaches a saved location and the
existing suspension setting is already higher than the level that has been saved for that location, the ride height is not adjusted.
To remove an auto-raising location
If you do not want the suspension to automatically raise
at a location, touch to deselect
Always raise at this
location in the popup that appears when you arrive at a
saved location.
Or, when using the Raise Suspension
shortcut on the main Controls window, touch to deselect
Location Saved.
Self-Leveling
Model S equipped with air suspension automatically self-
levels, even when power is
off. To prevent damage when
jacking or lifting the vehicle, you must activate
Jack
Mode to disable self-leveling (press the brake pedal and
touch
Controls > Service > Jack Mode). For more
details, see
Jack Mode on page 184.
