Driver assist systems -> Differential lock for Your Volkswagen California Van Third Generation (2015-2024)

Differential lock  
Fig. 1 In the dash panel: button for the differential lock  
(illustration).  
The differential lock ensures a mechanically rigid connection between the wheels on the rear axle so that it is not  
possible for there to be a difference in the rotational speeds of the wheels. When driving off-road, the differential  
lock improves traction in difficult terrain conditions, e.g. holes or surfaces with poor grip and when the vehicle is  
driving uphill  
.
Engaging the differential lock  
1. When travelling at a speed of less than approximately 45 km/h(28 mph), press → Fig. 1 button →  
.
The symbol in the button lights up continuously→ Fig. 1 as soon as the differential lock is engaged. Depending on  
the equipment, the yellow indicator lamp flashes or lights up in the instrument cluster.  
If the engine is switched off with the differential lock engaged, the differential lock remains engaged for around  
another 30 seconds.  
Switching off the differential lock  
1. Press the → Fig. 1 button again.  
The illuminated yellow symbol in the button→ Fig. 1 and the yellow indicator lamp in the instrument cluster go  
out.  
Do not engage the differential lock  
If you are driving on surfaced roads, e.g. asphalt→  
If the vehicle is being towed.  
.
When the drive wheels are spinning.  
If the brakes are being tested on a rolling road test bed.  
When driving down very steep hills.  
When the spare wheel is not the same as the other tyres mounted on the vehicle (→ Spare wheel or temporary  
spare wheel).  
Differential lock cannot be engaged  
The differential lock cannot be engaged in the following situations:  
When travelling at a vehicle speed of more than approximately 45 km/h(28 mph).  
222  
If there is a large difference in the speed of rotation of the rear wheels  
If the drive train is heavily loaded  
If the mechanical teeth of the differential lock are “tooth to tooth”: The symbol in the button and the yellow  
indicator lamp in the instrument cluster flash.  
WARNING  
The steering ability of the vehicle is very restricted when the differential lock is engaged. This could mean that you  
lose control over the vehicle and cause serious injuries.  
Never engage the differential lock if you are driving on a paved road surface, the vehicle is being towed or if the  
tyres have no traction.  
NOTICE  
Never engage the differential lock if you are driving on a paved road surface. If the differential lock is engaged, the  
axles, gearbox and drive shaft will be subjected to stresses, loading and damage during cornering.  
If the differential lock is switched off when driving through a bend, this may cause a small shudder to pass  
through the vehicle. This is caused by the release of tension forces in the drive train. This is normal and is not  
a indication of damage to the vehicle.  
If you drive through bends with the differential lock engaged, the wheels “rub” on the road surface. You  
might be able to hear this. The “rubbing” of the tyres - especially on solid ground - will lead to increased wear  
on the tyres.  
Introduction  
The cruise control system(CCS) helps to maintain a speed set by the driver.  
Speed range  
The CCS  
is available when driving forwards at speeds from around 30 km/h (around 20 mph).  
Driving with the cruise control system  
You can exceed the stored speed at any time, e.g. to overtake. Control is interrupted for the duration of the  
acceleration manoeuvre and is then resumed with the stored speed.  
Displays  
When the cruise control system is switched on, the instrument cluster display shows the stored speed and the status  
of the cruise control system.  
Depending on the driving situation and the instrument cluster version, one of following indicator lamps lights up:  
Cruise control system switched on.  
Cruise control system switched on, control intervention active.  
Cruise control system switched on, control intervention active.  
The indicator lamps are shown as small icons or are greyed out if the cruise control system is not regulating.  
If no speed is stored, the instrument cluster display shows  
instead of the speed.
