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.

x Set the parking brake.
x Switch on the ignition.
x Activate the function Mirror down in the Settings - Convenience menu.
x Turn the adjusting knob for the side mirrors to the R position.
x Shift the transmission into Reverse (R).
x Adjust the passenger outside mirror for a clear view of the curb, for example.
x The adjusted mirror position is automatically stored and assigned to the vehicle key used to unlock the vehicle. The preselected position will be recalled when the key assigned to that mirror adjustment position is used again.
Recalling passenger side mirror settings
x Turn the adjusting knob for the side mirrors to the R position.
x Shift the transmission into reverse gear with the ignition switched on.
x The mirror moves back to the regular position when the vehicle moves forward faster than about 10 mph (15 km/h) or the adjusting knob is turned to the O or L position.
WARNING
Improper use of the folding outside mirrors can cause personal injury.
x Always make sure that nobody is in the way when folding the mirrors in or out.
x Make sure that you do not get your finger caught between the mirror and the mirror base when moving the mirrors.
WARNING
Incorrectly estimating distances with the right outside mirror can cause collisions and serious 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.
x Never fold power mirrors in manually because doing so could damage the electrical drive.
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 pressing on the edges of the mirror surface.

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 and the sensors on the Tire Pressure
Monitoring System ⇒ page 259. 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.
There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System. The electronic Tire Pressure Monitoring System is more accurate.
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 inflation pressure in cold tires

WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were designed can cause sudden tire failure including a blowout and sudden deflation, loss of control, crashes and serious personal injuries.
x Winter tires have a maximum speed rating that may be lower than your vehicle's maximum speed.
x Never drive faster than the maximum speed for which the winter tires installed on your vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.
x Never exceed the maximum load rating for the winter tires installed on your vehicle.
Install summer tires promptly in the spring. Summer tires offer better handling characteristics for temperatures above +45 °F (+7 °C). They are quieter, do not wear as quickly, and reduce fuel consumption.
If factory-installed wheels and/or tires are replaced when installing winter tires, make sure that the wheels are equipped with sensors that are compatible with the factory-installed Tire Pressure
Monitoring System and that the tires are also compatible with the system⇒ page 238, New and replacement tires,.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.
If necessary, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility about permissible winter tire dimensions.

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, including 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 inflation pressure.
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure specified for the tires installed on the vehicle.
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 build-up, 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, Tires and wheels.
NOTICE
x The wheel electronics are attached to special aluminum valves on the wheels. These valves are screwed on rigidly. Never bend the valves “into position” when checking and adjusting tire pressure.
x Missing valve stem caps can cause damage to the valves as well as to the TPMS sensors. 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 stem caps.
x Do not use “comfort valve caps.” They do not seal properly and can damage the sensors.
x When replacing or rotating tires, make certain the valves and sensors are not damaged.
x The aluminum valves that are installed should be replaced after about 6 years of use because of aging in the rubber seals. The valves can be replaced when a tire is changed. Do not reuse aluminum valves after they are removed. They must be replaced. The tire pressure sensor can be reused.
x When replacing the valve cores, use only nickel-plated replacement cores.
x The batteries in the wheel electronics last up to 10 years. It is not possible to replace the batteries. The entire device must be replaced.
Underinflation increases fuel consumption and tire wear.

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.

Fig. 136 Fuel consumption in l/100 km at 2 different outside air temperatures.

Avoid unnecessary weight
The lighter the vehicle, the more economical and eco-friendly it will be. For example, an extra 220 lbs (100 kg) of weight increases fuel consumption by up to 1 pint per 60 miles (0.3 l/100 km).
Remove all unnecessary items and unnecessary dead weight from the vehicle.
Remove unnecessary aftermarket components
The more aerodynamic the vehicle, the less fuel it will consume. Aftermarket components such as bicycle racks reduce its aerodynamic performance.
Therefore, remove unnecessary structures and unused rack systems, particularly if planning to drive at higher speeds.
