Odometer displays
The odometer indicates the total distance driven by the vehicle.
The trip odometer (trip) shows the distance driven since the last time the trip odometer was reset. The last digit indicates 1/10 mile (100 meters).
Outside temperature display
At outside temperatures below about +39 °F (+4 °C), a “snowflake symbol” (icy road warning) appears in the display. The symbol flashes at first, then stays on until the outside temperature rises above
+43 °F (+6 °C) ⇒ .
When the vehicle is not moving or when you are driving at very low speeds, the temperature displayed may be slightly higher than the actual outside temperature.
The measurement range is from -40 °F (-40 °C) to +122 °F (+50 °C).
Compass display
When the ignition and navigation system are switched on, the current compass direction is indicated in
the instrument cluster display ⇒  Compass.
Selector lever positions
The selector lever position is shown both on the side of the selector lever and in the instrument cluster display. The respective gear may also be shown in the instrument cluster display in Drive (D) and Sport Drive (S), as well as in Tiptronic® mode.

Driving through water on roads

When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
x Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, stop the engine, turn on the emergency flashers, and use other warning devices to warn approach-ing traffic.
x Never park the vehicle in areas where the hot catalytic converter and exhaust system can come into contact with dry grass, brush, spilled fuel, oil, or other material that can catch fire.
x A broken down vehicle presents a high accident risk for itself and others. Switch on emergency flashers and set up a warning triangle to warn oncoming traffic.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
High Intensity Discharge (HID) headlights provide bright, uniform lighting to help you see and be seen. The light comes from an electric arc between two electrodes in the gas-filled bulb. Over time, the electrodes can wear down and the gap between them will get wider. The HID lamp’s control unit then increases the voltage to keep the arc’s brightness constant. However, the commonly called “Xenon” bulbs will also ultimately burn out. Before they burn out, HID lamps can flicker. A message will then appear in the MFI. This is your reminder to see an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to check the headlights.

Wiper performance in different situations:
During automatic
wipe/wash:
While the washer system is working, the
climate control system switches to recircula-
tion for about 30 seconds to help prevent the
washer fluid odor from entering the vehicle
interior.
During intermittent wiping: Speed-dependent interval control: The high-
er the vehicle speed, the faster the wipers
move.

Heated washer nozzles
The heating thaws frozen washer nozzles, but not the fluid supply hoses. When the ignition is switched on, the heat applied to the washer nozzles is automatically regulated depending on the outside air temperature.
Headlight washer system
The headlight washer system cleans the headlight lens.
If the ignition and the headlights (high or low beams) are switched on, the headlights are cleaned the first time and every fifth time the front windshield washers are activated. This happens only when the low or high beams are on when the windshield wiper lever is pulled towards the steering wheel. How-ever, the headlights must still be washed by hand periodically (for instance, during fueling) in order to get rid of hard-to-remove dirt (like insect splatter).
To help make sure that the headlight washer system works during winter weather, always keep the headlight washer nozzles free of snow and remove any ice with a deicer spray before driving. Use a deicer spray to remove any ice.
If there is something on the windshield, the wiper will try to wipe it away. If it continues to block the wiper, the wiper will stop moving. Remove the obstacle and switch the wiper on again.

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 Monitor-ing System (TPMS). 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.
Pressures measured with a gauge when inflating the tires may be different from the pressures read by the tire pressure sensors. The electronic TPMS 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 Pressure Monitoring System (TPMS).
Tire inflation pressure in cold tires

All-wheel drive (4MOTION)
Vehicles with all-wheel drive and standard road wheels have good forward motion and traction even under wintery road conditions. However, Volkswagen recommends installing snow tires or all season tires on all 4 wheels to improve handling as well as braking performance.
If you use snow chains, please read and heed information and directions ⇒  Snow chains.
WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were de-signed can cause sudden tire failure including a blowout and sudden deflation, loss of con-trol, 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 con-sumption.
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 (TPMS) and that the tires are also compatible with the system ⇒  Tire Pressure Monitoring System (TPMS). If new tires are not identical to those that were removed and require different cold tire inflation pressure, the tire inflation pressure values must be reprogrammed for the
TPMS. Please see your authorized Volkswagen dealer or authorized Volkswagen Service Facility ⇒  Tire Pressure Monitoring System (TPMS).
If necessary, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility about permissible winter tire dimensions.
Snow chains

Accessory weight

Bead separation
A breakdown of the bond between components in the bead.
Carcass
The tire structure, except tread and sidewall rubber which, when inflated, bears the load.
Chunking
The breaking away of pieces of the tread or sidewall.
Cord
The strands of material forming the plies in the tire.
Cord separation
The parting of cords from adjacent rubber compounds.
Cracking
Any parting within the tread, sidewall, or inner liner of the tire extending to cord material.
Cold tire inflation pressure

Key to ⇒ fig. 116
Position number Meaning
(5) No data received, right rear tire.
(6) Benchmark pressure, rear tires.

If the tire pressure is too low, the relevant tires and the respective readings are shown in yellow
⇒ fig. 116.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle plac-ard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's respon-sibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately 1 minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
Collapsible spare tire
The collapsible spare tire has no tire pressure sensor. When the collapsible spare tire is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS) indicator light will flash in the instrument cluster display. The TPMS continues to monitor the other 3 wheels.
Tire storage
If the tires do not move for an extended period of time, the sensors will not transmit tire pressures to the system. This saves sensor battery life. When the ignition is switched on, the sensors transmit signals to the Tire Pressure Monitoring System (TPMS).

WARNING
To reduce the risk of serious personal injury when starting and running the vehicle's engine:
x Never start the engine or let it run in a confined or enclosed area. Engine exhaust contains carbon monoxide, a poisonous, colorless, and odorless gas. Carbon monoxide can cause unconsciousness and death.
x Never leave the vehicle unattended with the engine running. The vehicle could move sud-denly or some other unexpected event could occur resulting in property damage or personal injury.
x Never use starting assist fluids. Starting fluids can explode and can cause a “run-away” vehicle condition.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Never apply additional undercoating or rust proofing on or near the exhaust manifold, exhaust pipes, catalytic converter, diesel particulate filter, or heat shields.
Warning and indicator lights

WARNING
Parking improperly can cause serious personal injury.
x Never remove the key from the ignition switch while the vehicle is moving or rolling to a stop. The steering wheel will lock and you will not be able to steer or control the vehicle.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Always apply the parking brake when parking your vehicle.
x Improper use of the parking brake can seriously injure you and your passengers.
x Never use the parking brake to slow down the vehicle when it is moving, except in an emergency. The stopping distance is much longer because only the rear wheels are braked. Always use the foot brake to stop the vehicle.
x Never activate the throttle manually from the engine compartment when the engine is running and the automatic transmission is in gear. The vehicle will start to move as soon as the engine speed increases even if the parking brake is on.
x Never leave children or anyone who cannot help themselves behind in the vehicle. They could release the parking brake and move the gear selector lever or gear shift, which could cause the vehicle to start moving. This can lead to a crash and serious personal injuries.
x Always take the key with you when you leave the vehicle. The engine can be started and vehicle systems such as the power windows can be operated, leading to serious personal injury.
x Never leave children, disabled persons, or anyone who cannot help themselves in the vehicle. The doors can be locked with the remote control vehicle key, trapping passengers in the vehicle in an emergency. For example, depending on the time of year, people trapped in the vehicle can be exposed to very high or very low temperatures.
x Heat buildup in the passenger and luggage compartment of a parked vehicle can result in temperatures in the vehicle that are much higher than the outside temperatures, particularly in summer. Temperatures can quickly reach levels that can cause unconsciousness and death, particularly to small children.
NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in height and could damage your bumper and related parts if the front of your vehicle hits a barri-er or curb that is too high while you are getting into or out of a parking spot. To help prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as bumper covers, spoilers, and parts of the engine, suspension, and exhaust systems).
