climate VOLKSWAGEN TIGUAN 2010 Owners Manual

Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside temperature. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.

Engines Engine oil specification
All gasoline engines VW 502 00, VW 503 00, VW 504 00

At the time this Manual was printed, the engine oils available in the U.S. that meet these Volkswagen standards are “synthetic” oils. This does not mean, however, that any “synthetic” engine oil will meet Volkswagen standards. Always use an approved oil that expressly complies with the Volkswagen oil quality standard that applies to your vehicle's engine.
General recommendations:
If “synthetic” oil that meets the applicable Volkswagen oil quality standard with viscosity grade SAE 5W-40 or SAE 5W-30 is not available in your area, be sure to use a viscosity grade suitable for the climate, season, and operating conditions that exist where the vehicle is used. Make sure the oil meets the quality standard listed in
Engine oils are constantly being improved. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities are always up-to-date regarding new developments and changes. Volkswagen therefore recommends that you have the engine oil changed by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
NOTICE
x If you need to add oil and there is none available that meets the Volkswagen oil quality standard your engine requires, you may add a total of no more than 1/2 quart (0.5 liter) of a high-quality “synthetic” oil that meets ACEA A3 specifications and has a viscosity grade of SAE 5W-40 or SAE 5W-30.
x Use only a high quality engine oil that expressly complies with the Volkswagen oil quality standard specified for your vehicle's engine. Using any other oil can cause serious engine damage that will not be covered by any Volkswagen Limited Warranty.
x Do not mix any lubricants or other additives into the engine oil. Doing so can cause engine damage! Damage caused by these kinds of additives are not covered by any Volkswagen Limited Warranty.
Engine oil capacities

To protect the engine, the mixture must always contain at least 40% coolant additive even in warm weather or climates where antifreeze protection is not needed.
If more antifreeze protection is needed for climate conditions, the percentage of coolant additive can be increased. However, the coolant additive percentage must never be more than 60%; otherwise, antifreeze protection is reduced and the ability of the mixture to cool the engine is also reduced.
When adding engine coolant, use a mixture of distilled water and at least 40% coolant additive G 13
or G 12 plus-plus (TL-VW 774 G) for optimum corrosion protection ⇒ .
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant additives together significantly reduces
corrosion protection ⇒  and can lead to engine damage that is not covered by any Volkswagen Limited Warranty.
WARNING
Too little antifreeze protection in the engine cooling system can cause engine failure and severe injuries.
x Always make sure there is enough of the correct coolant additive to provide proper antifreeze protection at the coldest temperatures that can be expected where the vehicle will be used.
x At extremely cold temperatures, the coolant could freeze, causing the vehicle to break down. The heater would also not work, and vehicle occupants could be without protection at subfreezing temperatures.
NOTICE
Never mix original Volkswagen engine coolant additives with other additives not approved by Volkswagen. Mixing Volkswagen coolant additives with coolant additives made by other manufacturers can seriously damage the engine and the engine cooling system.
x If the fluid in the engine coolant reservoir is any color but pink, then G 13 was mixed with a different engine coolant. If this is the case, the engine coolant must be replaced immediately. Otherwise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the environment. Collect leaking operating fluids and dispose of them properly in accordance with applicable environmental laws and regulations.

protection and damage electrical components, among other things. In addition, water could enter
directly into the vehicle interior through the plenum chamber ⇒ .
Never use a power washer to clean the engine compartment ⇒ .
If the engine compartment is extremely dirty, have it cleaned professionally by your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Plenum chamber
The plenum chamber is located in the engine compartment between windshield and engine, under a perforated cover. Outside air is taken into the vehicle interior from the plenum chamber via the climate control system.
Regularly remove leaves and other loose objects from the plenum chamber cover by hand or with a vacuum cleaner.
WARNING
Injuries, scalding, electric shock, accidents and fire hazards can occur while working on the engine or in the engine compartment!
x Before working in the engine compartment, be sure to familiarize yourself with the
necessary procedures and generally accepted safety precautions ⇒Working in the engine compartment.
x Volkswagen recommends having the work performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
NOTICE
Spraying or pouring water (e.g. with power washer) into the plenum chamber can cause severe damage to the vehicle.
Wash the engine compartment only in special wash bays so that the oily dirt and fuel residue that are washed off the vehicle will not enter the sewage system. In some areas it illegal to wash the engine compartment anywhere other than at such specified locations.
