Traction control system
The traction control system (TCS) helps maintain traction when accelerating on slippery surfaces, such
as unpaved 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 as needed until traction is restored.
EWA15433
WARNING
The traction control system is not a substitute for riding appropriately for the conditions. Trac-
tion control cannot prevent loss of traction due to excessive speed when entering turns, when
accelerating hard at a sharp lean angle, or while braking, and cannot prevent front wheel slip-
ping. As with any vehicle, approach surfaces that may be slippery with caution and avoid espe-
cially slippery surfaces.

2. TCS display
The " " indicator light flashes when traction control has engaged. You may notice slight changes in
engine and exhaust sounds when the system has engaged.
When the traction control system has been set to "OFF", the " " indicator light will come on.
The TCS display indicates the current TCS setting. There are three settings.
TCS "OFF"
TCS "OFF" turns the traction control system off.
TCS "1"
TCS "1" minimizes traction control system assist.
TCS "2"
TCS "2" maximizes traction control assist; wheel spin is most strongly controlled.
TIP
• When the key is turned to "ON", traction control is turned on and set to "1" or "2" (whichever was last
selected).
• Turn the traction control system off to help free the rear wheel if the vehicle gets stuck in mud, sand,
or other soft surfaces.

NOTICE
Use only the specified tires. Using different sized tires will prevent the traction control system
from controlling tire rotation accurately.

WARNING
Be sure to stop the vehicle before making any setting changes to the traction control system.
Changing settings while riding can distract the operator and increase the risk of an accident.
