(Tow/Haul): The vehicle may
have a Tow/Haul mode.
The button is located on the
instrument panel under the
climate controls.
Push the button to activate the
system. Push it again to deactivate
the system. You can use this feature
to assist when towing or hauling a
heavy load.
When Tow/Haul is activated

on the instrument panel cluster.
See Tow/Haul Mode under Driving
Characteristics and Towing Tips on
page 9 49 for more information.
Automatic Engine Grade
Braking
Automatic Engine Grade Braking
assists when driving on a downhill
grade. It maintains vehicle speed
by automatically implementing
a shift schedule that uses the
engine and the transmission to
slow the vehicle. The system will
automatically command downshifts
to reduce vehicle speed, until the
brake pedal is no longer being
pressed.
While in the Electronic Range
Select (ERS) mode, grade braking
is deactivated, allowing the driver
to select a range and limiting the
highest gear available. Grade
braking is available for normal
driving and in Tow/Haul mode.
See Automatic Transmission on
page 9 26.

All-Wheel Drive

Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare
tire on an AWD vehicle, the
system automatically detects the
compact spare and disables AWD.
To restore AWD operation and
prevent excessive wear on the
system, replace the compact spare
with a full-size tire as soon as
possible. See Compact Spare Tire
on page 10 78 for more information.
