2009 VOLKSWAGEN PASSAT Starting

Fig. 149 Emergency starting feature on vehicles with Keyless Access.

WARNING
Unintended vehicle movement can cause serious personal injury.
x Do not depress the brake or clutch pedals when switching on the ignition, as the engine could otherwise start immediately.
WARNING
Improper use of vehicle keys can result in serious personal injury.
x Always take the key with you when you leave the vehicle. Children or unauthorized persons may use it to lock the vehicle, start the engine, and operate vehicle systems such as the power windows, 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 using the remote control vehicle key. This could result in people being trapped 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 build-up 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.
In vehicles with a diesel engine and Keyless Access, the engine start may be delayed if the engine has to be preheated.
If the ignition is switched on or the engine is running and the driver door is opened, a chime sounds. The chime is also a reminder to switch off the engine and turn off the ignition before leaving and locking the vehicle from the outside.
Starting the engine

Please perform these steps only in the order listed.
Step Vehicles without Keyless AccessVehicles with Keyless Access
5. When the engine starts, release the vehicle key. When the engine starts, release the starter button.
6. If the engine does not start, switch off the ignition and start again after about 1 minute.If the engine does not start, switch off the ignition and start again after about 1 minute. Use the emergency start feature if necessary
7. Release the parking brake when you are ready to start driving
WARNING
Never leave the vehicle unattended while the engine is running. The vehicle could move suddenly, especially when the vehicle is in gear, resulting in accidents and personal injury.
WARNING
“Starting fluids” can explode and can cause a “run-away” vehicle condition.
x Never use starting assist fluids.
NOTICE
x You can damage the starter or the engine if you try to start the engine when the vehicle is still moving, or if you try to restart the engine right after switching it off.
x Avoid high engine speeds, full throttle acceleration, and heavy engine loads when the engine is cold.
x Do not try to start the engine by pushing or towing the vehicle. Unburned fuel can get into the catalytic converter and damage it. The steering column may also be locked.
Do not let your vehicle warm up while standing; instead, start driving right away after making sure that you have good visibility through all windows. This will help the engine reach operating temperature faster and keep down emissions.
Major consumers of electricity are temporarily switched off when the engine is being started.
After starting a cold engine, there may be increased operating noises for a few seconds. This is normal and harmless.
When outside temperatures are below +41 °F (+5 °C) and the diesel fueled preheater is activated, minor fume build-up may occur underneath the vehicle.

Adjust the tire pressure
The proper tire pressure helps reduce rolling resistance as well as fuel consumption.
When purchasing new tires, always make sure that the tires are optimized for lower rolling resistance.
Use low viscosity engine oil
Fully “synthetic,” low viscosity engine oils that expressly comply with Volkswagen oil quality standards reduce fuel consumption. Low viscosity engine oils reduce the frictional resistance on the engine and are distributed more evenly and quickly, particularly when cold-starting the engine. The effect is particularly apparent in vehicles that frequently travel short distances.
Always ensure the right engine oil level is maintained and keep to the scheduled service intervals (engine oil changes).
Make sure the engine oil that you purchase expressly complies with Volkswagen oil quality standards and is the oil approved by Volkswagen for your vehicle.
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.

Reverse (manual transmission) or in Drive (D), Sport Drive (S), or Reverse (R) (automatic transmission) and you must use the foot brake to hold the vehicle before starting to move.
Hill Hold keeps the brake applied for not quite 2 seconds with the same force you used to prevent the vehicle from moving. This gives you time to take your foot off the brake, let the clutch out on a manual transmission vehicle, and gently depress the accelerator to get the vehicle moving again. If you do not depress the accelerator pedal and get the vehicle moving again within this time, the brakes will release and the vehicle will roll downhill. Furthermore, if any requirement for engaging Hill Hold is no longer met while the vehicle is stopped, Hill Hold disengages and the brakes are automatically released and will no longer hold the vehicle.
Hill Hold is activated automatically when points 1 to 3 are met at the same time:

Manual transmissionAutomatic transmission
1. Hold the stopped vehicle on an incline with the foot or parking brake.
2. The engine must be running “smoothly.”
3. A manual transmission vehicle must be in 1st gear (1) if headed up a hill or in Reverse (R) if backing up a hill; you must hold the clutch down and the foot brake must be depressed to keep the vehicle from moving.
An automatic transmission vehicle must be in Reverse (R), Drive (D), or Sport Drive (S) and the foot brake must be depressed to keep the vehicle from moving.
4. To drive off take your foot off the brake pedal as you let the clutch out and gently depress the accelerator within 2 seconds.
To drive off take your foot off the brake pedal and gently depress the accelerator within 2 seconds.
Hill Hold is immediately deactivated:
x If any requirement listed in the table above is no longer met (see ⇒ page 244, Hill Hold is activated automatically when points 1 to 3 are met at the same time:).
x If the engine is not running smoothly or the engine malfunctions.
x If the engine stalls or is switched off.
x Automatic transmission vehicles: If the transmission is in Neutral (N).
x Automatic transmission vehicles: If a tire does not have enough road contact (such as when the vehicle is tipped or at an angle).
WARNING
The intelligent technology of Hill Hold cannot overcome the laws of physics. Never let the increased convenience provided by Hill Hold tempt you into taking risks.
x The Hill Hold feature cannot hold the vehicle in all hill start situations (for example, if the surface is icy or slippery).
x Hill Hold can only help keep the vehicle from moving for less than 2 seconds. After that, the brakes will be released and the vehicle can roll down the hill.

Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle battery has been replaced may change or delete settings (including time, date, personal convenience settings and programming). Check the settings and correct as necessary once the vehicle battery has built up a sufficient charge.

Octane rating
Octane rating indicates a gasoline's ability to resist engine-damaging “knock” caused by pre-ignition. Using the correct grade of gasoline is very important to help prevent engine damage and loss of engine performance.
The recommended gasoline octane rating for your engine is listed on a label inside of the fuel filler flap. This rating may be specified according to AKI (CLC) or RON (ROZ) standards.
If unleaded Premium grade gasoline is specified for your vehicle, then Volkswagen recommends using TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). For more information on TOP TIER Detergent Gasoline, please go to the official Web site http://www.toptiergas.com.
The gasoline grades most commonly sold in the United States and Canada have the following octane ratings, which can usually be found on the filler pump:
x Premium grade: 91 to 96 AKI
x Regular grade: 87 to 90 AKI
Unleaded gasoline
Unleaded gasoline is available throughout the USA and Canada. Volkswagen recommends that you do not take your vehicle to places where unleaded gasoline may not be available.
Gasoline containing alcohol or MTBE
You may use unleaded gasoline blended with alcohol or MTBE (methyl tertiary butyl ether), commonly referred to as oxygenated fuels, if the blended mixture meets the following criteria:
Blends of gasoline and methanol (wood alcohol or methyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 3% methanol.
x Blend must contain more than 2% co-solvents.
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 10% ethanol.
Blends of gasoline and MTBE:
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 15% MTBE.
Seasonally adjusted gasoline
Many fuels are blended especially for winter or summer conditions. When seasons change, Volkswagen suggests that you buy fuel at busy stations where the seasonal adjustment is more likely to be made earlier.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.
NOTICE
x Never use fuel with an octane rating lower than 87 AKI / 91 RON. Using lower octane fuel may cause expensive engine damage.
x Never use leaded gasoline! Leaded gasoline will severely damage your vehicle's catalytic converter.

x Methanol-blended fuels that do not meet the criteria listed above may cause corrosion and may damage plastic and rubber parts in the fuel system.
x Never use fuels that contain lead or other metals (check listing on the fuel pump). Even lead replacement gasoline (LRP fuels) contain metallic additives in high concentrations. They can damage the engine.
x Do not use fuels that fail to meet the criteria above, or with contents that cannot be identified.
x If you cannot tell whether a particular fuel blend meets the criteria above, ask your service station or its fuel supplier. If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel.
x Using fuels that are different from those specified above can damage your vehicle's engine and fuel system and cause performance problems.
x Damage to the engine and fuel system and performance problems caused by using fuels that are different from those specified above or by using “starting assist fluids” are not the responsibility of Volkswagen and are not covered under the Emission warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the catalytic converter and degrade its effectiveness in reducing polluting emissions.
If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel. Never use fuel line antifreeze offered for gasoline engines.
