Scheme 11

Note. Vehicles with a trailer hitch: extend the trailer hitch and attach the towing part or towing cable to the hitch.

Push the cap -arrow- with a single strong push toward the inside in order to loosen it from the bumper.

Install the towing eye all the way in the -direction of the arrow- into the threaded hole.

Scheme 12

Remove towing eye after use and return to vehicle tool kit storage compartment.

Tow starting or towing vehicle

Note. Tow-ropes or bars should be attached at above mentioned points only. The tow rope should be able to stretch to reduce the risk of damage to both vehicles. Therefore only ropes of synthetic material or rope from similarly flexible material should be used. However it is safer to use a tow bar! Avoid excessive towing effort and do not jerk. During towing operations on unpaved roads there is always a danger that the attachment points will be overstressed and damaged. Vehicle towing should only be done if it is not possible to start the engine with the starting assist cable.

If the vehicle must ever tow or be towed, observe the following

1. Legal regulations concerning towing must be observed.
2. Both drivers must be familiar with towing procedures. Inexperienced drivers should not attempt to tow start or tow.
3. When using a tow rope the driver of the towing vehicle must engage the clutch very gently when moving off and changing gear.
4. The driver of the vehicle being towed must ensure that the tow rope is always taut.
5. Both vehicles must have the emergency flasher switched on - if necessary observe any other regulations.
6. The ignition must be switched on, so that the steering wheel is not locked and the turn signals, horn, windshield wipers, and windshield washer system can be operated.
7. Since the brake booster only works with the engine running, the brake pedal must be stepped on with substantially more force when the engine is switched off.
8. With the engine switched off, the power steering also does not work, increasing the amount of steering effort.
9. Without lubricants in the manual transmission and/or automatic transmissions the car may only be towed with raised drive wheels.

Important notes for tow starting by vehicles

It is generally recommended not to tow start vehicles. Instead, jumper cables should be used.

There are several reasons to not tow start

1. During tow starting, the risk of an accident occurring is high, e.g. driving into vehicle towing.
2. Vehicles with gasoline engines can be damaged by unburned fuel entering the catalytic converter.
3. Tow starting of vehicles with automatic transmission is not possible for technical reasons.

If a vehicle should be tow started at any time, observe the following

Before tow starting, push in clutch pedal and hold, and select gear 2 or 3.

Switch the ignition on.

When both vehicles are in motion, release the clutch pedal.

As soon as the engine is started, push in the clutch and take the car out of gear to avoid running into the towing vehicle.

Note. Vehicles with catalytic converter (gasoline engine only) must not be started when the catalytic converter is at operating temperature and pulling the vehicle over a longer distance of more than 50 m. Otherwise, the vehicle could be damaged by unburned fuel entering the catalytic converter.

When towing a vehicle with automatic transmission the following additional points must be observed

1. Selector lever must be in the "N" position.
2. Do not tow at speeds greater than 30 mph (50 km/h).
3. The maximum towing distance is 30 miles (50 km).

For longer distances, the front end of the vehicle must be raised.

Reason: the transmission oil pump does not work when the engine is switched off. That means the transmission is not sufficiently lubricated at higher speeds and longer distances.

When towing with a tow truck, the vehicle may only be towed with raised front wheels.

Reason, the driveshafts turn backwards when the rear of the vehicle is raised. This would cause the planetary gears in the automatic transmission to achieve such high RPM that the transmission would be heavily damaged within a very short time.

Note. If normal towing of the vehicle is not possible, the vehicle must be transported with a special transporter or trailer. This also applies to towing distances of over 30 miles (50 km).

VEHICLE CHECKS DURING INSPECTION AND MAINTENANCE

For vehicle checks, we recommend interactive acceptance VAS 5000 and performance test stand V.A.G 1858.

The refractometer scale -1- is designed for coolant additives G11, G12, G12 Plus and G12 Plus Plus.

Scheme 47

The scale -2- is designed only for coolant additive -G 13-.

Coolant Additive, Checking

Note. The coolant portion of the mixture must amount to at least 40% (freeze protection down to -13°F (-25°C)) and should not exceed 60% (freeze protection down to -40°F/C), otherwise the freeze protection will be reduced and the cooling efficiency will be worsened. The freeze protection must be ensured down to at least -13°F (-25°C). If the climate requires more freeze protection, the portion can be increased.

Read the bright/ark boundary to obtain an accurate reading for the following tests.

Check the concentration of the coolant additive using refractometer T10007 A (operating instructions).

Place a drop of water on the glass with a pipette. The bright/dark boundary can be clearly recognized on the "WATERLINE".

If the freeze protection is too low, drain off required quantity shown in freeze protection table and add coolant additive G12 plus plus which corresponds to "TL 774 G" G13 which corresponds to "TL 774 J" COOLING SYSTEM, CHECKING FREEZE PROTECTION AND FILLING .

Check the freeze protection after the road test.

Coolant Level, Checking and Filling

Note. Coolant additive prevents freeze and corrosion damage, scaling, and raises the boiling point. For these reasons the cooling system must have coolant additive the whole year. Especially in countries with tropical climates or when vehicle is driven under heavy load, the coolant improves the engine reliability by its increased boiling point. The coolant concentration must not be reduced by adding water, even during the warmer season. The coolant additive ratio must be at least 40%. The coolant additive G12 plus plus may be mixed with coolant additives G13, G12 plus, G12 and G11. Permissible freeze protection

The vehicle must level.

Check the coolant level in the reservoir when the engine is cold.

If coolant level is too low, fill with coolant mixture.

DUST AND POLLEN FILTER WITH ACTIVATED CHARCOAL INSERT GENERAL INFORMATION

The filter with the activated charcoal insert performs the same task as the dust and pollen filter. It can also filter gaseous pollutants such as ozone, benzene, nitrogen, etc. out of the air inside the vehicle.

Because the activated charcoal layer also absorbs a portion of the gaseous particles permanently in addition to dust and pollen, the filter may need to be changed earlier than specified when under the following conditions

1. When operating the vehicle in areas with continuous heavy air pollution.
2. When operating a vehicle without an air quality sensor -G238- "Basis A/C System" and without automatic recirculating air mode.
3. When operating a vehicle with an air quality sensor -G238- "Comfort" A/C System with the "automatic recirculating air mode" off.

Note. If the vehicle has an air quality sensor -G238- and the "Comfort" A/C System, then the "automatic recirculating air mode" should be used all the time. The activated charcoal layer in the dust and pollen filter will become saturated after a certain amount of time. A saturated filter cannot absorb any more pollutants so they will enter the vehicle.

DUST AND POLLEN FILTER, REMOVING AND INSTALLING

Note. For the correct replacement interval, refer to the Maintenance, Diagnosis . Different versions: vehicles without A/C or with a manual A/C system have a dust and pollen filter without an activated charcoal filter. Vehicles with an automatic A/C system have an activated charcoal filter.

UNDERBODY PROTECTION, INSPECTING FOR DAMAGE

When inspecting visually, observe underbody, wheel housings and sills!

Check for loose wires and securing pieces.

PLENUM CHAMBER, WATER DRAIN CHECKING AND CLEANING

Note. The water in the plenum chamber may be blocked from being drained from the plenum chamber by debris (leaves, tree needles, etc.) that have collected there. This can cause the water blockage in the plenum chamber to increase (i.e. during car washes and heavy fog). The water drips into the grommet and through the fresh air intake shaft in the vehicle interior.

Remove the plenum chamber cover, only -2-. Refer to Removal and Installation .
