Traction control systemThe traction control system (TCS)
helps maintain traction when acceler-
ating on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip
(uncontrolled spinning), the traction
control system assists by regulating
engine power until traction is restored.
When traction control has engaged,
the “ ” indicator light will flash. You
may notice changes in engine re-
sponse or exhaust sound.
WARNING
EWA18860
The traction control system is not a
su bstitute for ri din g appropriately
for the con ditions. Traction control
cannot prevent loss of traction d ue
to excessive spee d when enterin g
turns, when acceleratin g har d at a
sharp lean an gle, or while b raking,
an d cannot prevent front wheel slip-
pin g. As with any vehicle, approach
surfaces that may be slippery with
caution an d avoi d especially slip-
pery surfaces.
Settin g the traction control system
When the vehicle is turned on, traction
control is automatically turned on.
To turn the traction control system off,
use the “MENU” switch to change the
multi-function display to the traction
control system display. Then push the
“MENU” switch for three seconds. The
display will show “TCS OFF”, and
the “ ” indicator light will come on.
TIPTurn the traction control system off to
help free the rear wheel if the vehicle
gets stuck in mud, sand, or other soft
surfaces.NOTICE
ECA16801
Use only the specifie d tires. (See
pa ge 9-19.) Usin g different size d
tires will prevent the traction control
system from controllin g tire rotation
accurately.
