SUZUKI SAFETY SUPPORT
(if equipped)
Dual sensor brake support
Dual sensor brake support is a system that detects a vehicle or a pedestrian in front of your vehicle by the dual sensor, attempts to avoid a collision by giving warning to the driver, and attempts to reduce damage in the event of a collision.
A WARNING
• Dual sensor brake support has lim­its and may not function properly depending on the driving condi­tions. Do not rely excessively on the system and always drive in a safe manner. For safety reasons, do not check the operation of the system by yourself. Check that all passengers fasten their seat belts when the vehicle is being operated. When the system is activated, there is a risk of serious injury from being thrown.
NOTE: While the system is working, if a vehicle in front of you moves outside the dual sensor's detection field or the vehicle can no longer be detected, the system may stop functioning. While the system is working, a braking sound may be heard even if you do not depress the brake pedal, but this is nor­mal. • As the function of the dual sensor brake support is different depending on some destinations or areas, there are type of vehicles with the function not to detect the pedestrians.

OPERATING YOUR VEHICLE
Automatic brake system When a frontal collision is unavoidable, the brakes will powerfully operate automatically. (#1)
Indicator Information display light
~ buzzer

(#1) After the vehicle has been stopped by the automatic brake system, the interior buzzer will continue to beep until the automatic brake system is released. Also, the indication on the information display and the dual sensor brake support indicator light will go off 3 seconds after the automatic brake system is released.
A CAUTION
After the vehicle has been stopped by the automatic brake system, immediately depress the brake pedal. If your vehicle is equipped with the automatic transmis­sion, and when the automatic brake system is released, the vehicle will start to move by the creeping function. This may result in an accident.
NOTE: If you do not depress the clutch pedal when the vehicle has been stopped by the auto­matic brake system, the engine will stall.

OPERATING YOUR VEHICLE
Braking
60G165S
The distance needed to bring any vehicle to a halt increases with the speed of the vehicle. The braking distance needed, for example, at 60 km/h (37 mph) will be approximately 4 times greater than the braking distance needed at 30 km/h (19 mph). Start to depress the brake pedal when there is plenty of distance between your vehicle and the stopping point, and slow down gradually.
3-53
A WARNING
If water gets into the brake devices, brake performance may become poor and unpredictable. After driving through water or washing the under­side of the vehicle, test the brakes while driving at a slow speed to see if they have maintained their normal effectiveness. If the brakes are less effective than normal, dry them by repeatedly applying the brakes while driving slowly until the brakes have regained their normal effectiveness.
Power-assisted brakes
Your vehicle has power-assisted brakes. If power assistance is lost due to a stalled engine or other failures, the system is still fully operational on reserve power and you can bring the vehicle to a complete stop by pressing the brake pedal once and holding it down. The reserve power is partly used up when you depress the brake pedal and reduces each time the pedal is pressed. Apply smooth and even pressure to the pedal. Do not pump the pedal.
A WARNING
Even without reserve power in the brake system, you can still stop the vehicle by pressing the brake pedal harder than normally required. How­ever, the stopping distance may be
longer.
Brake assist system
When you slam the brakes on, the brake assist system determines it to be an emer­gency stop and provides more powerful braking for a driver who cannot hold down the brake pedal firmly.

Anti-lock brake system (ABS)
ABS will help you avoid skidding by elec­tronically controlling braking pressure. It will also help you maintain steering control when braking on slippery surfaces or when braking hard. The ABS works automatically, so you do not need any special braking technique. Just push the brake pedal down without pumping. The ABS will operate whenever it senses that the wheels are locking up. You may feel the brake pedal move a little while the ABS is operating.
NOTE: The ABS will not work if vehicle speed is under about 9 km/h (6 mph). ff the ABS system is activated, you may hear a clunking noise and/or feel pulsat­ing in the brake pedal. This is normal and indicates that the brake fluid pres­sure is being controlled properly. You may hear an operation sound when you start the engine or after the vehicle begins to move. This means that the above systems are in the self-check mode. This sound does not indicate a malfunction.
A WARNING
On some types of loose surfaces (such as gravel, snow-covered roads, etc.), the stopping distance required for a vehicle with ABS may be slightly greater than the one required for a comparable vehicle with a conventional brake system. With a conventional brake system, skidding tyres are able to plow the gravel or snow layer, shortening the stopping distance. ABS minimizes this resistance effect. Allow for extra stopping dis­tance when driving on loose sur­faces. On regular paved roads, some driv­ers may be able to obtain slightly shorter stopping distances with conventional brake systems than with ABS. In both of the above conditions, ABS will still offer the advantage of helping you maintain directional control. However, remember that ABS will not compensate for bad road or weather conditions or poor driver judgment. Use good judg­ment and do not drive too fast.

OPERATING YOUR VEHICLE
A WARNING
If the ABS warning light (1) on the instrument cluster comes on and stays on while driving, there may be a problem with the ABS system. Ask a SUZUKI dealer to inspect the ABS system immediately. If the ABS system becomes inoperative, the brake system will function as an ordinary brake system that has no ABS. If the ABS warning light (1) and the brake system warning light (2) on the instrument cluster simultane­ously stay on or come on while driving, both anti-lock function and rear brake force control function (proportioning valve function) of the ABS system may have failed. If so, the rear wheels may easily skid or the vehicle can even spin in the worst case when braking on a slip­pery road or when hard braking even on a dry paved road. Ask a SUZUKI dealer to inspect the ABS system immediately. Drive care­fully, avoiding hard braking as much as possible.
3-55
How ABS works
A computer continuously monitors wheel speed. The computer compares the changes in wheel speed when braking. If the wheels slow suddenly. indicating a skidding situation, the computer will change braking pressure several times each second to prevent the wheels from locking. When you start your vehicle or when you accelerate after a hard stop. you may hear a momentary motor or clicking noise as the system resets or checks itself.
A WARNING
The ABS may not work properly if tyres or wheels other than those specified in the owner's manual are used. This is because the ABS works by comparing changes in wheel speed. When replacing tyres or wheels, use only the size and type specified in this owner's manual.
Electronic stability program
(ESP®)
ESP® is a registered trademark of Daimler
AG.
The Electronic Stability Program (ESP®) helps to control the vehicle during corner­ing if front wheels or rear wheels skid. It also assists you in maintaining traction while accelerating on loose or slippery road surfaces. It does this by regulating the engine's output, and by_ . selective!¥ applying the brakes. In add1t1on, ESP helps to avoid skidding by controlling brak­ing pressure.
A WARNING
The ESP® cannot enhance the vehi­cle's driving stability in all situations and does not control your vehicle's entire braking system. The ESP® can­not prevent accidents, including those resulting from excessive speed in turns, or hydroplaning. Only safe and attentive drive can prevent acci­dents. The capabilities of an ESP®­
equipped vehicle must never be used as a substitute for careful driving.

The ESP® has the following three sys­tems:
Stability control system
The vehicle stability control system helps provide integrated control of systems such as anti-lock brakes, traction control, engine control, etc. This system automatically controls the brakes and engine to help pre­vent the vehicle from skidding when cor­nering on a slippery road surface or when turning the steering wheel abruptly.
Traction control system
The traction control system automatically helps prevent the spinning of wheels when the vehicle is started or accelerated on slippery road surfaces. The system oper­ates only if it senses that some of the wheels are spinning or beginning to lose traction. When this happens, the system operates the front or rear brakes and reduces engine power to l1m1t wheel spin.
NOTE: You may hear an operation sound when you start the engine or after the vehicle begins to move. This means that the above systems are in the self-check mode. This sound does not indicate a malfunc­tion.
Anti-lock brake system (ABS)
ABS will help you avoid skidding by elec­tronically controlling braking pressure. It will also help you maintain steering control when braking on slippery surfaces or when braking hard. The ABS works automati­cally, so you do not have to use any spe­cial braking technique. Just push the brak_e pedal down without pumping. The ABS will operate whenever it senses that wheels are locking up. You may feel the brake pedal pulsate while the ABS is operating. (For more information on ABS, see "Brak­ing" in this section.)
NOTE: The ABS will not work if vehicle speed is under about 9 km/h (6 mph).
A WARNING
The ESP® may not work properly if tyres or wheels other than those specified in the owner's manual are used. When replacing tyres or wheels, use only the size and type specified in this owner's manual. • The ESP® may not work properly if ·tyres are not inflated to the recom­
mended ~re pressure. The ESP" may not work properly if tyres are fitted with snow chains. (Continued)
OPERATING YOUR VEHICLE
A WARNING
(Continued) • The ESP® may not work properly if the tyres are excessively worn. Replace tyres when the tread wear indicators in the grooves appear on the tread surface. • The ESP® is not a substitute for winter tyres or snow chains on a snowMcovered road.
A WARNING
• The ESP® may not work properly if engine related parts such as the muffler are not equivalent to stan­dard equipment or are extremely deteriorated. Do not modify the vehicle's sus­pension since the ESP® may not work properly.
NOTE: • If the Espi!) system is activated, you may hear a clunking noise and/or feel pulsat­ing in the brake pedal. This is. normal and indicates that the brake flwd pres­sure is being controlled properly. You may hear an operation sound when you start the engine or after the vehicle begins to move. This means that the above systems are in the self-check mode. This sound does not indicate a malfunction.
