● If the engine does not start after 10 seconds, turn the key back to posi-
tion 1
. Repeat the action after 30 seconds.
● Release the handbrake before moving off.
Switching off the engine
Stop the engine by turning the ignition key to position 1 ⇒ Fig. 101

Brakes and brake servo systems Introduction
WARNING
● The brake servo only works when the engine is running. Braking
when the engine is switched off requires more strength on the brake ped-
al. Risk of accident!
● Press down on the clutch pedal when stopping and braking with a
manual gearbox, petrol engine vehicle at low speed. Otherwise, the
brake servo might not work properly. Risk of accident!
● In the event of damage to the standard front spoiler or where a differ-
ent front spoiler, hubcaps, etc. are subsequently fitted, make sure the air
vent to the brakes on the front wheels is not blocked. Otherwise, braking
operations may be impaired. Risk of accident!
● Always fully release the handbrake. If it is only partially released, this
will cause overheating of the rear brakes, which can impair the function
of the brake system. Risk of accident!
WARNING (Continued)
● Never leave children unsupervised in the vehicle. They could release
the handbrake or move the gear lever. The vehicle could start moving.
Risk of accident!
● Insufficient fuel can cause the engine to run irregularly or to switch
off. Brake assist systems could be impaired. Risk of accident!
● Always adjust your driving style to suit visibility, the weather and
road and traffic conditions. The best vehicle safety offered by brake as-
sist systems must never encourage you to run greater risks. Risk of acci-
dent!
CAUTION
● Observe the information concerning new brake pads ⇒ page 157.
● Where braking is not necessary, do not wear down the brake pads by
pressing down gently on the brake pedal. This causes the brakes to over-
heat, increasing their wear and increasing braking distances.
● To ensure the brake assist systems work properly, all wheels must be fit-
ted with tyres approved by the manufacturer.
Note
● If you brake suddenly and the brake system control unit regards the sit-
uation as hazardous for the drivers behind you, the brake lights will begin
to flash automatically. After reducing speed to approx. 10 km/h (6 mph) or
stopping the vehicle, the brake lights will stop flashing and the hazard
warning lights will switch on. The hazard warning lights are automatically
switched off when you accelerate or restart the vehicle.
● On long, steep gradients, reduce your speed and change to a lower gear
(manual gearbox) or move the selector lever to a lower gear position (auto-
matic gearbox). This uses the force of the engine and the brakes do not suf-
fer as much. If you still have to brake, do so intermittently, pressing down
repeatedly on the brake pedal.
