Fig. 226 Fuel consumption in litres per 100 km at two different outside temperatures.
r-1"'11 First read and observe the Introductory Information and safety warnings&. on page 278.
By adopting an economical driving style and antici-pating the traffic situation ahead, you can easily re-duce fuel consumption by 10-15%.
Cars use most fuel when accelerating. If you think ahead when driving, you will need to brake less and thus accelerate less. Wherever possible, let the car roll slowly to a stop, for instance when you can see that the next traffic lights are red.
Avoid short journeys
Directly after a cold start, the engine has a very high fuel consumption. The engine reaches its working temperature after a few kilometres, when fuel consumption will return to a normal level.
The engine and catalytic converter need to reach their proper working temperature in order to mini-mise fuel consumption and emissions. The out-side temperature is a key factor.
The different rates of fuel consumption for the same distance at both +20"C (+68"F) and at -10"C (+14"F) are shown in Fig. 226.
Therefore, avoid making too many short journeys and car share whenever possible.
Under the same conditions, the vehicle will use more fuel in winter than in summer.
280 I While dnvmg
Not only is it illegal in some countries to "warm up" the cold engine by running it while the vehicle is stationary, it is also technically unnecessary and a waste of fuel.
Adjust the tyre pressure
The correct tyre pressure reduces rolling resist-ance and therefore also fuel consumption.
Ensure that any new tyres purchased have opti-mum rolling resistance.
Use low viscosity engine oils
Fully synthetic low viscosity engine oils reduce fuel consumption. Low viscosity engine oils decrease frictional resistance in the engine and spread bet-ter and more quickly, especially for cold starts. They are especially effective In vehicles that make alotofshortjourneys.
Always ensure that the engine oil level is correct and that you keep to the service intervals (oil change intervals).
When buying engine oil, always make sure it com-plies with engine oil norms and has been approved by Volkswagen Commercial Vehicles.
Avoid unnecessary loads
Lighter vehicles are more economical and have lower environmental impact. An extra 100 kg, for example, can increase fuel consumption by up to 0.311100 km.
Remove all unnecessary objects and loads from the vehicle.
Remove any unnecessary special equipment and accessories
The more aerodynamic a vehicle, the lower its fuel consumption. Special equipment and accessories, such as roof carriers or bicycle carriers, make the vehicle less aerodynamic.
You should therefore remove any special equip-ment and luggage carriers that are not in use, es-pecially if you are going to be driving at high speeds.

Locking the steering wheel
• When the vehicle key has been removed, turn the steering wheel slightly until you hear the lock-ing pin engage.
The steering should be locked every time you leave the vehicle to make il more difficult for the vehicle to be stolen.
Unlocking the steering wheel
• Turn the steering wheel slightly to lake the load off the steering lock mechanism. Hold the steering wheel in this position and tu m the vehicle key clockwise out of position 217 @.
A WARNING
If the power steering is not working, the steering wheel is difficult to turn, which makes it difficult to steer the vehicle.
• The power steering only functions when the engine Is running.
• Never allow the vehicle to roll if the engine is switched off.
• Never remove the vehicle key from the ig-nition lock when the vehicle is in motion. The steering lock may be activated and you will no longer be able to steer the vehicle. Power steering
With power steering, the steering assistance is au-tomatically matched to vehicle speed, the steering wheel torque and the steering wheel angle. The power steering will only function when the engine is running.
You will need considerably more strength than nor-mal to steer the vehicle if lhe power steering is re-duced or has failed completely. Starting the engine, changing gear and parking I 281

l"'""'('n First read and observe the Introductory L-W.I Information and safety warnings & on page 282.
The Hill Descent Assist system supports
the driver when driving down a steep in-
cline by actively braking the vehicle.
The Hill Descent Assist reduces the engine speed and brakes actively so that the vehicle travels con-stantly at walking speed =>&.
The requirement for regulation is, among other things, that the ground allows enough grip. The Hill Descent Assist system cannot fulfil its function when driving down an icy or slippery slope.
Hill Descent Assist is regulating
• If the Hill Descent Assist is switched on using the button and the indicator lamp lights up.
• AND: the speed is less than 30 km/h (19 mph).
• AND: the gradient is at least 10%.
• AND: if the accelerator and brake are not de-pressed.
• AND: if the engine is running.
Regulation is stopped if the vehicle is accelerated or braked by the driver during regulation. The regu-lation restarts once the requirements are met again.
Hill Descent Assist does not regulate
• If the gradient is less than 10%.
• OR: The speed is greater than 30 km/h (19 mph).
• OR: If the driver brakes or accelerates.
A WARNING
Always be prepared to brake the vehicle. Ac-cidents and Injuries could occur if this is not ensured.
• The Hill Descent Assist system is only a support function and may not be able to brake the vehicle sufficiently In all situations when driving downhill.
• The vehicle may accelerate despite the Hill Descent Assist system.
Switching the Hill Descent Assist on and off
• To switch the Hill Descent Assist on, press the @=>Fig. 228 button in the centre console at speeds under approximately 30 km/h (19 mph). The indicator in the instrument cluster dis-play lights up. The indicator lamp flashes when the Hill Descent Assist system is applying the brake.

Not switching the rear axle differential lock on
• If you are driving on well-surfaced roads &.
• If the vehicle is being towed.
• If the brakes are being tested on a rolling road test bed.
286 I While dnving
Rear-axle differential lock cannot be switched on
The rear axle differential lock cannot be switched on in the following situations:
• if there is a large difference in the speed of ro-tation of the rear wheels
• if the drive train is loaded heavily
• If the mechanical teeth of the rear-axle differen-tial lock are '1ooth to tooth": the indicator light r. in the instrument cluster flashes.
A WARNING
Never switch the rear axle differential lock on If you are driving on a solid road surface, the vehicle is being towed or if the tyres have no traction.
• Your steering will be greatly Impaired when the rear axle differential lock has been switched on. This could mean that you lose control over the vehicle and cause serious In-juries.
CD
Switching the rear axle differential lock on while being towed can damage the drive train.
m If the rear axle differential lock is switched off W when driving through a bend, this may cause a small shudder to go through the vehicle. This is caused by the release of wind-up in the drive train. This is normal and is not a indication of damage to the vehicle.
m If you drive through bends with the rear axle W differential lock switched on, 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.

m If there is a function fault in the ParkPilot, an W acoustic warning is emitted for approximately 3 seconds when switched on for the first time. The ParkPilot should be checked by a qualified work-shop immediately. ParkPilot front and rear
