SAFETY PRECAUTIONS FOR NEW VEHICLES THAT ARE BEING PUT IN STORAGE - AP00.70-P-1000ZZ 

MODELS all  

and rear axle 
Frame

 

New vehicles in the 
context of this description 
are vehicles for which no 
inspection has been carried 
out to date. For other 
vehicles, the instructions 
in the Specifications for 
Service Products apply

 

 

 

In areas in which 
extremely high corrosive 
attacks can be expected 
from experience, the 
measures given here are 
not always sufficient even 
for new vehicles

Export countries 
In these cases, proceed in 
accordance with 
Specifications for Service 
products.

 

 

Treatment of battery if 
vehicle taken out of 
service

 

AR54.10-P-0006EA 

 

Treatment of tire inflation 
pressure if vehicle taken 
out of service

For vehicles which will be 
stored for longer than 2 
months, the tire inflation 
pressure should be 
increased to approx. 4 bar 
to prevent flattening of the 
contact surface.

 

 

Treatment of break system 
if vehicle taken out of 
service

Warm up service brake so 
that adhering moisture at 
the brake disks and the 
brake pads evaporates. 
This prevents the brake 
pad from becoming stuck 
to the brake disks. 
Release parking brake. 
The vehicle must be 
secured by engaging a 
gear/park pawl or by using 
wedges.

 

 

Treatment of fuel system 
if vehicle taken out of 

To protect the fuel tank 
from corrosion, we
