is mechanically blocked in this position. The brake pedal must be depressed and the igni-tion must be in at least mode II (see Ignition
modes (p. 73)) before the gear lever can bemoved from the P position.
WARNING
Always apply the parking brake when the vehicle is parked, particularly when park-ing on a hill. The transmission's P mode
may not be able to keep the vehicle sta-tionary if it is parked on an incline.
Press the control to apply the parking brake, see Parking brake – general information(p. 254).
CAUTION
The vehicle must be stationary when posi- tion P is selected.
Gear indicatorThe gear currently being used is displayed on the rightside of the instrument panel. The " S" symbol turns orange
if Sport mode is being used.
Reverse: position RThe vehicle must be stationary when position R is selected.
Neutral: position NNo gear is engaged and the engine can bestarted with the gear selector in this position.Apply the parking brake if the vehicle is sta-tionary with the gear selector in position N. In
order to move the gear selector from the N
position, the brake pedal must be depressedand the ignition must be in at least mode II.
Drive: position DD is the normal driving position. The car auto-
matically shifts between the various forwardgears, based on the level of acceleration andspeed. The car must be at a standstill whenshifting from position R to position D.

Brake pad inspectionOn vehicles equipped with a jack*, the condi- tion of the brake pads can be checked byraising the vehicle (see Changing a wheel –removing wheel (p. 276) for informationabout using the jack and removing a wheel)and performing a visual inspection of thebrake pads.
WARNING
• If the vehicle has been driven immedi- ately prior to a brake pad inspection,the wheel hub, brake components,etc., will be very hot. Allow time forthese components to cool before car-rying out the inspection.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
WARNING
•Use the jack intended for the vehicle when changing a tire. For any otherjob, use stands to support the vehicle.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• Be sure the jack is on a firm, level,non-slippery surface.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
• The jack must correctly engage thejack attachment.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is run-ning. Never let the vehicle roll to a stop withthe engine switched off. If the power brakes are not working, consid- erably higher pressure will be required on thebrake pedal to compensate for the lack ofpower assistance. This can happen for exam-ple when towing your vehicle or if the engineis switched off when the vehicle is rolling. Thebrake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water tocollect on the brake discs and pads. This willcause a delay in braking effect when thepedal is depressed. To avoid such a delaywhen the brakes are needed, depress thepedal occasionally when driving through rain,slush, etc. This will remove the water from thebrakes. Check that brake application feelsnormal. This should also be done after wash-ing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strainwhen driving in mountains or hilly areas, orwhen towing a trailer. Vehicle speed is usuallyslower, which means that the cooling of thebrakes is less efficient than when driving onlevel roads. To reduce the strain on thebrakes, shift into a lower gear and let theengine help with the braking. Do not forgetthat if you are towing a trailer, the brakes willbe subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. Thisdelay is minimized by cleaning the brake lin-ings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and afterthe vehicle has been washed. Do this by

Anti-lock braking system (ABS)
The ABS system helps to improve vehicle control (stopping and steering) during severebraking conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically modulatedin order to help prevent lockup that couldlead to a skid. The system performs a brief self-diagnostic test when the engine has been started anddriver releases the brake pedal. Another auto-matic test may be performed when the vehi-cle first reaches a speed of approximately6 mph (10 km/h). The brake pedal will pulsateseveral times and a sound may be audiblefrom the ABS control module, which is nor-mal.

Brake lights
The brake lights come on automatically when the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event of sudden braking or if the ABS system isactivated. This function causes an additionaltaillight on each side of the vehicle to illumi-nate to help alert vehicles traveling behind. The adaptive brake lights activate if: •The ABS system activates for more than approximately a half second
• In the event of sudden braking while thevehicle is moving at speeds aboveapproximately 6 mph (10 km/h).
When the vehicle has come to a stop, the brake lights and additional taillights remain onfor as long as the brake pedal is depressed oruntil braking force on the vehicle is reduced.

Emergency Brake Assistance (EBA)
EBA is designed to provide full brake effect immediately in the event of sudden, hardbraking.
Emergency Brake AssistanceThe EBA system is activated by the speedwith which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brakesystem immediately increases to the maxi-mum level. Maintain full pressure on thebrake pedal in order to utilize the systemcompletely. EBA is automatically deactivatedwhen the brake pedal is released.
NOTE
• When the EBA system is activated, the brake pedal will go down and pressurein the brake system immediatelyincreases to the maximum level. Youmust maintain full pressure on thebrake pedal in order to utilize the sys-tem completely. There will be no brak-ing effect if the pedal is released. EBAis automatically deactivated when thebrake pedal is released.
• When the vehicle has been parked forsome time, the brake pedal may sinkmore than usual when the engine isstarted. This is normal and the pedalwill return to its usual position when itis released.
