slippery road conditions, the engine
speed and torque increases to help
prevent locking of the drive wheels

Limited-slip rear axle
Rear-wheel drive vehicles may be
equipped with an automatic locking
rear differential which automatically
controls the torque transmitted toeach rear wheel, enhancing traction
in the event of soft ground, mud or
snow-covered road surfaces.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
When vehicle speed reaches
20 mph, or once the rear wheels
return to surfaces with normal grip,
e.g. paved roads, the system
automatically deactivates,
sometimes accompanied by a noise
(with no consequence to vehicle
behaviour).
The system can also be deactivated
manually once normal grip conditions have resumed by briefly releasing the
accelerator.
