Differential locks
General notes
GWARNING
When the differentiall ocks are engaged,ABS,
4ETS, ESP
®and BAS are deactivated. As a
result, the wheelsc ould lock when braking
and the braking distance is increased.T here is
ar isk of an accident.
Disengage the differentiall ocks immediately
on firm surfaces with good grip.
!In order to avoid damage to the transfer
case, you must operate the vehicle on adyna-
mometer (1-axle dynamometer) only if:
Rthe axle not driven on is jacked up
or
Rthe corresponding propeller shaft is dis-
connected and the transfer case differen-
tial lock is engaged.
Otherwise,t he transfer case can be damaged.
Differential locks improve the traction of the
vehicle.
Your vehicle is equipped with adifferentiall ock
each for:
Rthe transfer case: this controls the balance
betweent he front and rear axles.
Rthe rear axle: this controls the balance
betweenthe wheelsont he rear axle.
Rthe front axle: this controls the balance
betweenthe wheelsont he front axle.
Information on differential gear system
and differential lock
When the vehicle drives around acurve, the
wheelsont he outsideoft he curve must cover a
greater distance. Therefore, the wheelst urn
more rapidly than on the inside. The differential,
ag ear system in the drive train, allows for dif-
fering rotational speedsa nd facilitates corner-
ing.
