Range b Diesel engines only: Estimated distance in miles (km) that the vehicle can go with the AdBlue left in the tank. Visible only when the AdBlue range has fallen to less than 1500 mi or 2400 km.

WARNING
A wet seat can cause the seat heating to malfunction and increase the risk of serious burns.
x Always make sure the seats are dry before using the seat heating.
x Never sit on the seat with wet clothes.
x Never put damp or wet things including clothes on the seat.
x Never spill liquids on the seats.
NOTICE
x To help prevent damage to electrical and other parts in the seat, do not kneel on the front seats or apply concentrated pressure to a small area of the seat or backrest.
x Liquids, sharp objects and things that do not let the heat in the seat escape into the air, including, for example, a child restraint, a blanket, or seat covers on the seat can damage seat heating.
x If you smell an odor, immediately shut off seat heating and have it checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
x Never install leather upholstery on a vehicle with seat heating that originally had cloth upholstery. The seat heating elements for seats with cloth seats will overheat if the cloth up-holstery is replaced with leather upholstery.
Switch off seat heating when it is not needed to help reduce unnecessary fuel consumption.

WARNING
Incorrectly estimating distances with the right outside mirror can cause collisions and seri-ous injury.
x The right outside mirror has a convex (curved) surface. This widens your field of vision. But vehicles or other objects seen in a convex mirror will look smaller and farther away than they really are.
x If you use the right outside mirror to judge distances from vehicles behind you when changing lanes, you could estimate incorrectly and cause a crash and serious injuries.
x Whenever possible, use the inside mirror to more accurately judge distance and size of vehicles or other objects seen in the convex mirror.
x Always make sure you have a clear view to the rear of the vehicle.
NOTICE
Always fold in the outside mirrors when taking the vehicle through an automatic car wash.
To reduce fuel consumption, use outside mirror heating only when needed.
When first switched on, outside mirror heating works with maximum heat for about 2 minutes.
If power mirror adjustment does not work, the outside mirrors can be adjusted by hand by press-ing on the edges of the mirror surface.

x Make sure that the luggage compartment lid does not touch items on the roof rack when opened.
If a roof rack is installed, fuel consumption increases due to increased air resistance.
Attaching the roof rack base carrier and roof rack

Fig. 97 Attachment points for the base carrier and roof rack.

Inflate the compact spare wheel to the pressure specified for the compact spare on the tire pressure label or on a separate label for the compact spare, if there is one.
WARNING
Incorrect tire pressure can cause a sudden tire failure or blowout, loss of control, collision, serious personal injury, and even death.
x Always inflate tires to the recommended and correct cold tire pressure before driving off.
x Low tire pressure can cause tires to get too hot, resulting in tread separation, sudden loss of pressure, and blowouts. Tires with excessively low pressure flex (bend) more, which can cause the tire to overheat and fail suddenly without warning.
x Excessive speed and/or overloading can cause heat buildup, sudden tire failure including a blowout and sudden deflation and loss of control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.
x Regularly check tire inflation pressure, at least once a month, and also especially before a long trip.
x Check the pressure in all 4 tires when the tires are still cold. Never reduce air pressure in warm tires to match cold tire inflation pressure.
NOTICE
x Make sure not to jam the tire pressure gauge into the valve stem. Otherwise you can dam-age the tire valves.
x Driving without valve caps, with the wrong valve caps, or with valve caps that are not properly screwed on can damage the tire valves. To help prevent damage, always use valve stem caps like those originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve caps or “comfort” valve stem caps.
Underinflation increases fuel consumption.
When the TPMS warns that the pressure in at least one tire is too low, check the tire pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be spotted by looking
at the tire. This is especially true for low-profile tires. When checking the tire pressures, refer to ⇒  Tire Pressure Monitoring System (TPMS).
Tire inflation pressure in cold tires

WARNING
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, collision, serious personal injury or even death.
x When the warning symbol appears in the instrument cluster, stop and inspect the tires.
x Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the handling of the vehicle and stopping ability.
x Incorrect tire pressures and/or underinflation can also lead to sudden tire failure, includ-ing a blowout and sudden deflation, causing loss of vehicle control.
x The driver is responsible for the correct tire pressures for all tires on the vehicle. The
recommended tire pressure values are listed on a sticker inside the driver door ⇒  Tire infla-tion pressure.
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure.
x Using incorrect tire pressure values can cause accidents or other damage. Always inflate the tires to the correct specified cold tire pressure values for the tires installed on the vehicle.
x Always maintain correct cold tire inflation pressure so that TPMS can do its job.
x Always inflate tires to the recommended and correct tire pressure before driving off.
x Driving with underinflated tires causes them to flex (bend) more, letting them get too hot, resulting in tread separation, sudden tire failure, and loss of control.
x Excessive speed and/overloading can cause heat buildup, sudden tire failure and loss of control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.
x If the tire is not “flat” and you do not have to change a wheel immediately, drive carefully and at reduced speed to the nearest service station to check the tire pressure and add air as required.
x When replacing tires or wheel rims on vehicles equipped with TPMS always read and heed
the information and all WARNINGS regarding ⇒  Tires and wheels.
x The Tire Pressure Monitoring System must be recalibrated using the SET button whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire
pressure does not change ⇒  Tire Pressure Monitoring System (TPMS) and recalibration with the SET button.
WARNING
Improper use of the SET button can cause the TPMS to give false warnings or to give no
warning despite dangerously low tire pressure ⇒  Tire Pressure Monitoring System (TPMS) and recalibration with the SET button.
Underinflation increases fuel consumption and tire wear.
Do not rely solely on the Tire Pressure Monitoring System. Check your tires regularly to make sure they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any objects that become embedded in the tire tread but have not penetrated into the body of tire itself.

speed fluctuations caused by taking your foot off the accelerator. Active braking and accelerating is then not necessarily required.
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 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.
