WARNING
Transporting heavy or bulky loads on the roof rack will change
the way the vehicle handles by shifting the vehicle's center of
gravity and increasing the wind drag.
Always secure the load properly with suitable and undam-
aged straps so that the load will not shift.
Cargo that is large, heavy, bulky, long or flat will have a nega-
tive effect on the vehicle's aerodynamics, center of gravity and
overall handling.
Always avoid sudden maneuvers and hard braking.
Always adapt your speed and driving to the heavier load and
the weight distribution in the vehicle. Take road, weather, traf-
fic, and visibility conditions into account as well.
NOTICE
Always remove the roof rack before driving through an auto-
matic car wash.
Your vehicle is higher when the roof rack is installed, especial-
ly when it is loaded. Compare the vehicle height with existing
clearance heights, such as underpasses and garage doors.
Always make sure that the roof rack system and anything be-
ing carried on it does not interfere with the roof antenna, the
power sunroof or the luggage compartment lid.
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 in-
creased air resistance.

inflation pressure sensors ⇒  Tire Pressure Monitoring System
(TPMS).
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
⇒  Tire Pressure Monitoring System (TPMS). To help prevent
damage, always use valve stem caps like those originally in-
stalled 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 Pressure Monitoring System (TPMS).
Tire inflation pressure in cold tires

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 consump-
tion.
If factory-installed wheels and/or tires are replaced when in-
stalling 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 sys-
tem. If new tires are not identical to those that were removed and re-
quire different cold tire inflation pressure, the tire inflation pressure
values must be reprogrammed for the TPMS. Please see your author-
ized Volkswagen dealer or authorized Volkswagen Service Facility ⇒ 
The Tire Pressure Monitoring System must be recalibrated 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 author-
ized Volkswagen Service Facility about permissible winter tire dimen-
sions.
Snow chains

miles (kilometers) at low speeds in the 3 hour period before the tire
pressure is measured or adjusted.
Curb weight
The weight of a motor vehicle with standard equipment including the
maximum capacity of fuel, oil, and coolant, air conditioner, and addi-
tional weight of optional equipment.
Extra load tire
A tire designed to operate at higher loads and at higher inflation pres-
sures than the corresponding standard tire.
Gross Axle Weight Rating (GAWR)
The load-carrying capacity of a single axle system, measured where
the tire contacts the ground.
Gross Vehicle Weight Rating (GVWR)
The maximum loaded weight of the vehicle.
Groove
The space between 2 adjacent tread ribs.
Load rating (code)
The maximum load that a tire is rated to carry for a given inflation
pressure. You may not find this information on all tires because it is
not required by law.
Maximum load rating
The load rating for a tire at the maximum permissible inflation pres-
sure for that tire.
Maximum loaded vehicle weight
The total of:
Curb weight.
Accessory weight.
Vehicle capacity weight.
Production options weight.
Maximum (permissible) inflation pressure
The maximum cold inflation pressure to which a tire may be inflated.
Also called “maximum inflation pressure.”

If the tire pressure is too low, the relevant tires and the respective
readings are highlighted in yellow.
Each tire, including the spare (if provided), should be checked month-
ly when cold and inflated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard or tire inflation pres-
sure label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard 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 under-
inflated. 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. Under-
inflation 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 mainte-
nance, and it is the driver's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indi-
cator 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 one minute and then remain continuously illuminat-
ed. 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 malfunc-
tions 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 mal-
function 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.

WARNING
Switching off the engine while the vehicle is moving can make
the vehicle harder to stop and result in loss of vehicle control,
leading to collisions and severe personal injuries.
Brake and steering assistance systems, the airbag system,
safety belt pretensioners, and other vehicle safety features only
work when the engine is running.
Switch off the engine only when the vehicle is not moving.
WARNING
To reduce the risk of serious personal injury when starting and
running the vehicle's engine:
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 un-
consciousness and death.
Never leave the vehicle unattended with the engine running.
The vehicle could move suddenly or some other unexpected
event could occur, resulting in property damage or personal
injury.
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 get very
hot. They can cause fires and serious personal injury.
Never park the vehicle where the hot exhaust system or cata-
lytic converter could ignite flammable materials, such as brush,
leaves, dry grass, spilled fuel, etc.
Never apply additional undercoating or rust proofing on or
near the exhaust manifold, exhaust pipes, catalytic converter,
or heat shields.

WARNING
Parking improperly can cause serious personal injury.
Never remove the key from the ignition switch while the vehi-
cle is moving or rolling to a stop. The steering wheel will lock
and you will not be able to steer or control the vehicle.
Never park the vehicle where the hot exhaust system or cata-
lytic converter could ignite flammable materials, such as brush,
leaves, dry grass, spilled fuel, etc.
Always apply the electronic parking brake when parking your
vehicle.
Improper use of the electronic parking brake can seriously
injure you and your passengers.
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.
Never activate the throttle manually from the engine com-
partment when the engine is running and the automatic trans-
mission is in gear. The vehicle will start to move as soon as the
engine speed increases even if the parking brake is on.
Never leave children or anyone who cannot help themselves
behind in the vehicle. They could switch off 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.
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.
Never leave children, disabled persons, or anyone who can-
not 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.

Facing downhill, turn the front wheels so that they point toward the
curb.
Facing uphill, turn the front wheels so that they point away from the
curb.
WARNING
The vehicle exhaust system and the catalytic converter get very
hot. They can cause fires and serious personal injury.
Never park where the hot exhaust system could ignite flam-
mable materials, such as brush, leaves, dry grass, spilled fuel,
etc.
NOTICE
Always be careful when you park in areas with parking barri-
ers or high curbs. These vary in height and could damage your
bumper and related parts if the front of your vehicle hits a barrier
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.
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 ex-
haust systems).
About the brakes

Vehicles with gear recommendation aid in fuel efficient driving by in-
dicating the optimum time to shift gears.
Coasting
If you take your foot off the accelerator, fuel delivery to the engine is
interrupted, which lowers fuel consumption.
Therefore, when nearing a red stop light, for instance, allow the vehi-
cle to coast without using the accelerator. Press the clutch pedal and
release it only if the vehicle moving too slowly or the coasting dis-
tance is too long. The engine will then continue to run at idle.
In situations where the vehicle will be stopped for a longer period of
time, such as at a railroad crossing, physically switch off the engine.
Defensive driving and “flowing” with traffic
Frequent braking and acceleration increase fuel consumption signifi-
cantly. Just by driving defensively and keeping a sufficiently large
distance away from the vehicle in front of you can make up for the
speed fluctuations caused by taking your foot off the accelerator. Ac-
tive 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 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 (exam-
ples):
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

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 opti-
mized 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 vis-
cosity 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. Af-
termarket 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.
