failure. If you have added non-distilled water, take the vehicle
immediately to an authorized Volkswagen dealer or an author-
ized Volkswagen Service Facility to have the coolant system
drained, flushed, and refilled completely with the proper coolant.
Refill engine coolant only up to the top edge of the marked fill
range ⇒ fig. 168. Excess engine coolant may be forced out of the
engine cooling system when it gets hot and cause damage.
In the case of significant engine coolant loss, refill engine
coolant only when the engine is completely cooled down. Signif-
icant engine coolant loss is a sign of leaks in the cooling sys-
tem. Have the engine cooling system checked immediately by an
authorized Volkswagen dealer or an authorized Volkswagen Ser-
vice Facility. Otherwise the engine may be damaged!
When changing or topping off operating fluids, make sure that
you pour the fluids into the correct reservoirs. Serious malfunc-
tions and engine damage can result if you pour operating fluids
into the wrong reservoir.

Checking the vehicle battery acid level
If the lighting conditions are poor, use a flashlight so that you can
clearly see the battery acid level indicator and tell what color it is.
Never use an open flame or an unprotected light source.
The round battery window (“acid level indicator”) on the top of the
battery changes color, depending on the battery's electrolyte level.

8. Set up a warning triangle or other warning device in order to alert
other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.
If the emergency flashers are on, use the turn signal lever to indicate
a direction or lane change, for example when the vehicle is being
towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
Traffic suddenly slows down or stops in front of you to warn those
approaching from behind.
In any emergency situation.
If the vehicle breaks down.
When being towed.
Always obey traffic laws that govern the use of emergency flashers
where you are driving.
If the emergency flashers are not working, a different method – as
permitted by law – must be used to alert other motorists and cyclists
to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents
and serious personal injuries.
Always review and follow the checklist. Follow accepted safe-
ty practices and use common sense.
WARNING
The vehicle exhaust system and the catalytic converter get very
hot. They can cause fires and serious personal injury.
Never park where parts of the hot exhaust system or catalytic
converter could ignite flammable materials, such as dry grass,
brush, leaves, spilled fuel, etc.
The vehicle battery will be drained if the emergency flashers are
on for a long time – even if the ignition is switched off.

The vehicle may only be lifted by a jack positioned at one of the four
jack lift points ⇒ .
Checklist
For your own safety and that of your passengers, carry out the follow-
ing steps in the order listed ⇒ .
1. Find a level spot on firm ground for lifting the vehicle.
2. Switch off the engine. Automatic transmission: shift the transmis-
sion into Park (P)) ⇒  Automatic transmission: Selector lever. Man-
ual transmission: shift into a gear ⇒  Manual transmission: Gear-
shift lever. Then set the electronic parking brake ⇒  Braking and
parking to help prevent the vehicle from moving.
3. If towing a trailer: Unhitch the trailer from the vehicle and park the
trailer properly.
4. Straighten the steering wheel so that the front wheels point straight
forward.
5. Block the diagonally opposite wheel with chocks or other suitable
things.
6. Loosen the wheel bolts of the wheel to be changed ⇒ Wheel bolts.
7. Find the jack lift point on the vehicle frame that is closest to the
wheel to be changed.
8. Remove the cover panel in the side sill. To do so, pull forcefully but
carefully in the direction of the arrow ⇒ fig. 193. Secure the cover
panel with the retaining strap.
9. Crank up the vehicle jack so that it still just fits underneath the lift
point.
10. Position the jack so that its base is directly underneath the lift
point ⇒ fig. 194, making sure that the entire base of the jack rests
securely on the ground.
11. Align the jack and wind up the jack claw at the same time, until
the claw cradles the vertical rib underneath the vehicle ⇒ fig. 194.
12. Continue raising the vehicle jack until the wheel is lifted off the
ground.

WARNING
Disregarding the safety-related checklist may lead to accidents
and serious personal injuries.

and easier on both vehicles than using a tow rope. A tow rope should
be used only if a tow bar is not available.
The tow rope should be flexible enough to help protect both vehicles
from damage. Use a synthetic fiber rope or similar rope.
Attach the tow rope or tow bar only to the towing eye included in the
vehicle tool kit for this purpose, or to a trailer hitch.
Towing manual transmission vehicles
Check whether your vehicle can be towed at all; see below ⇒  When
not to tow your vehicle
If yes, not the following for the towed vehicle:
Shift the gearshift lever to Neutral ⇒  Shifting.
Do not tow faster than 30 mph (50 km/h).
Do not tow more than 30 miles (50 km).
Towing automatic transmission vehicles
Check whether your vehicle can be towed at all; see below ⇒  When
not to tow your vehicle
If yes, not the following for the towed vehicle:
Put the transmission in Neutral (N).
Do not tow faster than 30 mph (50 km/h).
Do not tow more than 30 miles (50 km).
When a commercial tow truck is being used, the vehicle must only
be towed with the front wheels lifted off the ground.
Follow the special instructions for towing vehicles with all-wheel
drive (4MOTION).
Towing vehicles with all-wheel drive (4MOTION)
Vehicles with all-wheel drive (4MOTION) should be towed with a tow
bar or a tow rope. If the vehicle is towed with the front or rear axles
lifted off the ground, the engine must be switched off. Otherwise the
powertrain may be damaged.
For vehicles with the DSG® Direct Shift Gearbox, also follow the di-
rections on how to tow a vehicle with automatic transmission ⇒  Tow-
ing automatic transmission vehicles.
