BRAKE FLUID REPLACEMENT INTERVAL
Our braking technology, and in particular the disc
brakes (hollow pistons which conduct little heat, have a
low volume of fluid in the cylinder, sliding callipers
avoiding the need for a fluid reserve in the least cooled
area of the wheel), has allowed us to prevent the risk of
« vapour lock » as far as possible, even with heavy
braking (mountainous area). However, current brake
fluids are subject to minor deterioration during the first
months of use due to slight humidity intake. This is why
it is recommended that you change the brake fluid: see
maintenance booklet for the vehicle.
1 - Topping up the level
Wear of the brake pads will result in a gradual drop in
the fluid level in the reservoir.
Do not top up the fluid, as the level will rise again when
the pads are next changed. The brake fluid level must
not fall below the minimum mark.
2 - Approved brake fluid
Mixing two incompatible brake fluids in the brake circuit
may lead to:
-serious risk of leakage due mainly to deterioration of
the cups,
-deterioration in the operation of the ESP system.
To prevent such risks, it is essential to use only brake
fluids that comply with the RENAULT standard (see
Vehicle: Parts and consumables for the repair) .

aPut the vehicle in the VODM position (vehicle in run-
ning order) (see 30A, General information, Under-
body heights: Adjustment value, page 30A-24) :
-tank full,
-vehicle empty (without luggage, etc.).
aConsult:
-the front axle geometry values (see 30A, General
information, Front axle assembly: Adjustment
values, page 30A-31) ,
-the rear axle geometry values (see 30A, General
information, Rear axle assembly: Adjustment
values, page 30A-38) .
aRefer to the user manual for the geometry tester.
aCheck the geometry using the geometry tester.
aIf there is an inconsistency between the manufactur-
er's values and the measured values:
aAdjust the front axle (see 30A, General informa-
tion, Front axle system: Adjustment, page 30A-
