Checking the coolant level
> Park the vehicle on a level surface.
> Switch the ignition off.
> Open the hood > page 241.
The coolant expansion tank is located in the ple-
num chamber under a cover. Slide the cover that
is located below the windshield wipers on the
front passenger's side toward the windshield and
remove the cover > page 242, fig. 157.
> Read the coolant level on the floating gauge for
the expansion tank without opening the cap.
The coolant level must be between the Min and
Max markings when the coolant is cold
> fig. 158
> 1 turns on, do not continue driving
=> page 242.
> If the coolant level is just over the Min marking,
drive to an authorized Audi dealer or authorized
Audi Service Facility immediately.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.
Z\ WARNING

cle can be a dangerous area. Switch the igni-
tion off and allow the cooling system to cool
down. Always follow the information found
in > page 240, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the motor
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the motor
compartment with caution.
— The coolant expansion tank may only be
opened and filled by an authorized Audi
dealer or authorized Audi Service Facility.

— When adding coolant, it may leak into the
inside of high-voltage components and
cause a short circuit, increasing the risk of
fire.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
