WARNING
Driving with bad brakes can cause a collision and serious per-
sonal injury.
If the brake warning light "2!+% or H does not go out, or
comes on when driving, either the brake fluid level in the reser-
voir is too low or there is a fault in the brake system. Stop the
vehicle as soon as you can do so safely and get expert assis-
tance ⇒  Brake fluid.
If the brake warning light "2!+% or H comes on at the same
time as the ABS warning light !"3 or J, the ABS may not be
working properly. This could cause the rear wheels to lock up
relatively quickly during braking. Rear wheel brake lock-up can
cause loss of vehicle control.
If you believe the vehicle is safe to drive, drive slowly and
very carefully to the nearest authorized Volkswagen dealer, au-
thorized Volkswagen Service Facility, or other qualified work-
shop and have the brake system inspected. Avoid sudden hard
braking and steering.
If the ABS indicator light !"3 or J does not go out, or if it
comes on while driving, the ABS system is not working proper-
ly. The vehicle can then be stopped only with the standard
brakes (without ABS). You will not have the protection ABS
provides. Contact your authorized Volkswagen dealer or an au-
thorized Volkswagen Service Facility as soon as possible.
If the symbol "2!+% 7%!2 or I lights up in the instrument clus-
ter display, whether alone or together with a text message, im-
mediately contact an authorized Volkswagen dealer or author-
ized Volkswagen Service Facility to have the brake pads
checked and, if necessary, replaced.
NOTICE
Failure to heed warning lights or text WARNINGS can result in
vehicle damage.

following other vehicles too closely) – especially during the break-in
period.
Brake pad wear depends mostly on operating conditions and the
way the vehicle is driven. If you do a lot of city and short-distance
driving and/or have a sporty driving style, you should have the brake
pads checked by an authorized Volkswagen dealer or authorized
Volkswagen Service Facility more often than the regular service inter-
vals.
Wet brakes (for example, after driving through water or washing the
vehicle or after heavy rainfall) will not brake as well. Stopping dis-
tances will be longer when brake discs are wet or, in winter, even icy.
Wet or icy brakes must be dried as soon as possible by carefully ap-
plying the brakes a couple of times while traveling at a relatively high
speed. Make sure nobody is behind you and that you do not endan-
ger yourself or others ⇒ .
Brakes coated with road salt also react slower and need longer
stopping distances. If there is salt on the roads and you are not brak-
ing regularly, brake carefully and gently from time to time to remove
any salt coating from the brake discs and pads ⇒ .
Brake disc corrosion (rust) and dirt buildup on the brake pads are
more likely to occur if the vehicle is not driven much or is driven only
for short distances with little braking. If the brakes have not been
used and there is some rust on the discs, clean the brake discs and
pads once in a while by carefully braking a couple of times while driv-
ing at relatively high speed to help clean the brake discs and pads.
Make sure nobody is behind you and that you do not endanger your-
self or others ⇒ .
Brake system malfunction
If you brake and find that the vehicle doesn't brake nearly as well as it
used to (sudden increase in stopping distance), a brake circuit may
have failed. The brake warning light H or "2!+% will come on and a
message may appear in the instrument cluster display. If you believe
the vehicle is safe to drive, immediately take it to the nearest author-
ized Volkswagen dealer or authorized Volkswagen Service Facility for
repair. Drive slowly and very carefully, allow for the longer stopping
distance, and be ready to push longer and harder on the brake pedal
to slow the vehicle down.

WARNING
Wet brakes or brakes coated with ice or road salt react slower
and need longer stopping distances.
Carefully apply the brakes to test them.
Always dry brakes and clean off ice and salt coatings with a
few cautious brake applications when visibility, weather, road
and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stop-
ping distances and can cause accidents and serious personal
injuries.
Never let the vehicle coast when the engine is switched off.
If the brake booster is not working (such as when the vehicle
is being towed), a lot more pedal force is needed to slow down
and stop.
NOTICE
Never “ride” the brakes by keeping your foot on the brake pe-
dal when you do not want to brake. Constant pressure on the
brake pedal can make the brakes overheat. Riding the brakes
will substantially reduce braking performance, increase stopping
distance, and can cause complete brake system failure.
Before driving downhill, especially on hills that are long or
steep, always reduce speed and shift into lower gear (manual or
automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake
system could overheat and possibly fail. Only use the brakes
when you need them to slow the vehicle down more or to stop.
When the front brakes are serviced, you should have the rear
brake pads inspected at the same time. The wear of all brake pads
should be visually checked regularly. The best way to check for brake
pad wear is to have your authorized Volkswagen dealer or authorized
Volkswagen Service Facility visually inspect the pads through the

Check the information on the container for the brake fluid you want to
use to make sure it meets the requirements for your vehicle.
Brake fluid that complies with VW Standard 501 14 can be pur-
chased from your authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
If this special brake fluid is not available you may – under these cir-
cumstances – use another high quality brake fluid that complies with
U.S. Federal Motor Vehicle Safety Standard (FMVSS) 116 DOT 4 ⇒ 
.
Please note, however, that not all brake fluids that comply with U.S.
Federal Motor Vehicle Safety Standard FMVSS 116 DOT 4 have the
same chemical composition. Some of these brake fluids can contain
chemicals that could, over time, degrade or damage internal parts of
the vehicle’s brake system.
Volkswagen therefore recommends that you use brake fluid that ex-
pressly complies with VW Standard 501 14 for optimum brake sys-
tem performance over the long term.
Brake fluid level
The fluid level in the transparent brake fluid reservoir must always be
between the MIN and MAX marking ⇒ .
On some vehicles, engine components block the view of the brake
fluid reservoir and make it impossible to see the brake fluid level. If
you cannot clearly see the brake fluid level in the brake fluid reservoir,
please see an authorized Volkswagen dealer or authorized
Volkswagen Service Facility.
The brake fluid level drops slightly when the vehicle is being used as
the brake pads wear and the brakes are automatically adjusted.
Changing brake fluid
Brake fluid must be changed according to the service schedule in
your ⇒ Booklet Warranty and Maintenance. Have the brake fluid
checked by an authorized Volkswagen dealer or an authorized
Volkswagen Service Facility. Refill only with new brake fluid that
meets the standards listed above.

WARNING
Brake failure and reduced brake performance can be caused by
not having enough brake fluid in the reservoir or by old or in-
correct brake fluid.
Check the brake system and brake fluid level regularly.
Always change the brake fluid according to the service
schedule in your ⇒ Booklet Warranty and Maintenance.
Hard braking with old brake fluid may cause vapor lock. Va-
por lock reduces braking performance, increases stopping dis-
tances and can even cause total brake failure.
Always make sure that only the correct brake fluid is used.
Only use brake fluid that expressly conforms to VW Standard
501 14 or, if it is not available, only use a high-quality brake flu-
id that conforms to U.S. Standard FMVSS 116 DOT 4 require-
ments.
Using another brake fluid, or one that is not of high quality,
can impair the function of the brake system and reduce its ef-
fectiveness. If the container does not say that the brake fluid
complies with VW Standard 501 14, or U.S. Standard
FMVSS 116 DOT 4, do not use it.
The brake fluid must be new.
WARNING
Brake fluid is poisonous.
To reduce the risk of poisoning, never use food, beverage or
other non-original containers to store brake fluid. Someone
might be misled by the original label on the container, or by the
shape of the container, and drink the brake fluid. This could oc-
cur even if you relabel the container as “brake fluid.”
Only store brake fluid in the closed, original container and
keep it out of the reach of children.
NOTICE
Brake fluid will damage vehicle paint, plastic parts, and tires.
Wipe any brake fluid off vehicle paint and other vehicle parts
immediately.

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.

WARNING
Failure to heed warning lights and instrument cluster text mes-
sages can cause the vehicle to break down in traffic and result
in a collision and serious personal injury.
Never ignore warning lights or text WARNINGS.
Always stop the vehicle as soon as it is safe to do so.
NOTICE
Failure to heed warning lights or text WARNINGS can result in

1) Do not use Rear Assist in the following situations:
– If the area behind the vehicle cannot be seen clearly or complete-
ly.
– If the rear of the vehicle is heavily loaded.
– When the luggage compartment lid is open.
– If the driver is not familiar with the system.
– If the position or angle of the camera has changed, such as after a
rear-end collision. Have the system checked by an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility.


2) Examples of optical distortion by the camera:
The Rear Assist camera displays only two-dimensional images. Re-
cesses and protruding objects on the ground or protruding parts on
other vehicles are difficult or impossible to identify due to the lack of
depth of field.
Objects or another vehicle may seem closer or farther away on the
screen than they really are:
– When driving from a level surface onto an upward or downward
slope.
– When driving up or down a slope onto a level surface.
– If the rear of the vehicle is heavily loaded.
– When approaching protruding objects. These objects can disap-
pear from the field of view when backing up.

Cleaning the camera lens
Keep the camera lens clean and free of snow and ice:
Engage the parking brake.
Switch on the ignition.
