Symptom Electrical Accessories
Issue:
Customers reporting that the Deployable Side Steps are
failing to deploy.
Cause:
If a customer is driving in Automatic Terrain Response
Program's then under certain road conditions the vehicle
will seamlessly switch between any of the 5 operational
modes without notifying the customer. This feature is to
give the customer the most enhanced driving experience
possible.
The Deployable Side Step system is designed to not
function in the following 3 Terrain Programs.
- MUD - RUTS
- SAND
Content - ROCK CRAWL
As a consquence if the vehicle automatically enters into
one of these 3 modes then the Deployable Side Step
System will not deploy by design.
Action:
If a customer reports that their Side Steps are failing to
deploy with the vehicle in Automatic Terrain Response
Program's then the attached documentation can be given.
This details the interaction of the Automatic Terrain
Response Program and the Deployable Side Step system
and highlights the reason for non-deployment.
It also details a method of deactivating the Automatic
Terrain Response Program feature which will allow the
General Program (Special Program's Off) or GRASS /
GRAVEL / SNOW Program to be selected. This will then
allow the Deployable Side Steps to deploy as intended.

selected, or
• The vehicle determines that GENERAL
PROGRAM (SPECIAL PROGRAMS OFF) or
GRASS/GRAVEL/SNOW program is
suitable for the current driving style and
conditions.

overriding AUTO program or any TERRAIN
RESPONSE programs to ensure that side
steps can be deployed safely.
