Instruments and electrical equipment
1. Check the operation of all devices and electrical equipment.
2. Make sure that all instrument readings are correct and all electrical equipment is functioning properly.
Steering and suspension
1. Check for faults in the steering and suspension.
2. Drive the vehicle and check that there are no unusual vibrations or noises.
3. Check that the steering is smooth and the steering wheel can be turned without excessive force.
Chassis
1. Check the operation of the engine and clutch (where applicable), gearboxes/transmissions and drive shafts.
2. Pay attention to any unusual noises from the engine, clutch and gearbox/transmission.
3. Make sure the engine runs smoothly at idle and there is no hesitation when accelerating.
4. Check where applicable that the clutch operates smoothly, the drive is transmitted smoothly and the pedal free play does not exceed that specified in the Certifications. Note any noises produced when the clutch pedal is depressed.
5. On models with manual transmission, make sure all mechanisms operate smoothly and without noise.
6. On models with automatic transmission, check that gear changes are smooth, without increasing engine speed between shifts. Check that any gear change mode can be selected with the engine switched off. If any problems are detected, contact a Renault service center.
7. Listen for a metallic sound while driving the vehicle slowly in a circle with the steering angle at maximum. If a clicking noise is heard, this indicates wear in the drive shaft connection.
Brake system
1. Make sure that the vehicle does not pull to one side when braking and that the wheels do not lock prematurely when braking hard.
2. Make sure that there is no vibration in the steering when braking.
3. Make sure the handbrake holds the vehicle on the slope.
4. Check the operation of the brake booster as follows. Turn off the engine and press the brake pedal four or five times to remove the vacuum. Press the brake pedal and hold it, then start the engine. Once started, the brake pedal should become weak as a vacuum has been created in the system. Let the engine run for at least two minutes, then turn it off. If you now press the brake pedal, you should hear a hissing sound from the servomotor. After pressing it four or five times, there should be no hissing sound and the pedal should feel much firmer.
