improved.
For more information if the GPS

road surfaces such as in sand,
gravel, and/or snow.
.The vehicle is traveling on
winding roads or long straight
roads.

exiting a parking lot, garage,
or a lot with a roof.
.The GPS signal is not received.
.A roof carrier is installed on the
vehicle.
.Tire chains have been installed.

Driving and Operating 9-13
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
Shifting the vehicle into L will allow
the driver to achieve more wheel
spin. The wheel spin will still be
limited by the traction control
system to prevent any driveline
damage. The increase in allowable
wheel spin is only active at low
speeds.{WARNING
If the vehicle's tires spin at high
speed, they can explode, and
you or others could be injured.
The vehicle can overheat,
causing an engine compartment
fire or other damage. Spin the
wheels as little as possible and
avoid going above 55 km/h
(35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑69.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little
as possible. The Traction Control
System prevents the tires from
spinning at high speeds. To prevent
electric drive unit wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the electric drive unit is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see Towing the Vehicle on
page 10‑84.
