Hill descent control system
The hill descent control system is designed to reduce the driver's workload when going down steep, rough and/or slippery hills where the vehicle cannot decelerate enough by engine braking alone. The hill descent control system helps to control vehicle speed by automatically engaging the vehicle's brakes, as needed, so you can concentrate on steering the vehicle.
.A. WARNING
Do not rely excessively on the hill descent control system. The hill descent control system may not con­trol the vehicle speed on a hill under all load or road conditions. Always be prepa!ed to control vehicle speed by applying the brakes. Failure to pay attention and control vehicle speed using the brakes when necessary may result in loss of control or an accident.

To activate the hill descent control system: 1) Shift the transfer lever into 4-wheel drive hiQh range position ("4H") or 4-wh!"el drive low '.ange position ("4L"). 2) Shift the gearsh1ft lever into a forward gear or reverse gear. 3) Push the hill descent control switch (1) when the vehicle speed is under 25 km/h (15 mph). The hill descent control indica­tor on the instrument cluster will come on and the hill descent control system will be activated.
4-wheel drive high range position When the vehicle speed exceeds about 1 o km/h (6 mph) without depressing the accelerator pedal, the hill descent control system applies the brakes automatically to maintain the vehicle speed at about 1 O km/ h (6 mph).
4-wheel drive low range position When the vehicle speed exceeds about 5 km/h (3 mph) without depressing the accelerator pedal, the hill descent control system applies the brakes automatically to maintain the vehicle speed at about 5 km/h (3 mph).
• When braking, the brake/tail lights come on and the ESP® warning light blinks. When the vehicle speed exceeds about 40 km/h (25 mph), the hill descent con­trol system stops functioning and the hill descent control indicator goes off. When the vehicle slows down below about 25 km/h (16 mph), the hill descent control system will be activated again and the hill descent control indicator will come on.

A WARNING
• When the hill descent control sys­tem is used continuously for a long time, the temperature of the bra~e system may increase and the hill descent control system may be deactivated temporarily to protect the device of the brake system. The hill descent control indicator blinks to let you know the system is deac­tivated. Depress the brake pedal and stop the vehicle in a safe place. When the temperature of the brake system goes down, the hill descent control indicator will come on and the system is activated again. • The hill descent control system may be activated when the gear­shift lever is in "N" (Neutral) posi~ tion, but engine braking will not work. Always use the hill descent control system with the gearshift lever in a forward gear or reverse
gear. When using the hill descent control system, push the hill descent con­trol switch and make sure that the hill descent control indicator light comes on and no warning message are indicated on the information display.
NOTE: You may hear a sound coming from the engine when the hill descent control sys­tem is activated. This sound is normal and does not indicate a malfunction.

A WARNING
(Continued) After you release your foot from the brake pedal, accelerate the vehicle to move up immediately. If you release your foot from the brake pedal over 2 seconds, the hill hold control system will be canceled. If so, the vehicle may roll downward, which can result in an accident depending on the degree of slope. And, the engine may stall and the power assist for the steering and brakes will not work so steering and braking will be much harder than usual which can result in an accident or vehicle damage. If you drive on the steep slope, the gravel, the sclnow-covered road, or the muddy r I'd and the hill hold control system is activated, there may be a possibility that the wheels will be locked and then the vehicle may lose the control.
The hill hold control system activates for a maximum of about 2 seconds if your foot is moved from the brake pedal when the fol­lowing conditions are all met.
1) The gearshift lever is in a forward gear or reverse gear. 2) The parking brake is released. 3) The vehicle is on an upward incline.
NOTE: When the hill hold control system is acti­vated, the following conditions may be found, but this is not a malfunction. You may hear a sound from the engine room. As brake pedal becomes heavy, it may be difficult for you to depress it.

OPERATING YOUR VEHICLE
TPMS malfunction indicator
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is com­bined with the low tyre pressure telltale. When the system detects a malfunction, the telltale will flash for about 75 seconds and then remain continuously illuminated. This sequence will continue upon subse­quent vehicle start-ups as long as the mal­function exists.
The TPMS malfunction indicator is not reset even after the engine is turned off; it remains in the ON state until the normal conditions are restored.
When the malfunction indicator is illumi­nated, the system may not be able to detect or signal low tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tyres or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction tell­tale after replacing one or more tyres or wheels on your vehicle to ensure the replacement or alternation of tyres and wheels to allow the TPMS to continue to function properly.

NOTICE
The tyre pressure sensors can be damaged if you do not take proper precautions.
We highly recommend that you have tyres repaired or replaced by a SUZUKI dealer. The tyre pressure sensors can be damaged by instal­lation or removal of tyres. • Do not use liquid sealants for a flat tyre unless your vehicle is equipped with a flat tyre repair kit instead of a spare tyre.
NOTICE
If the low tyre pressure warning light comes on frequently, there may be something wrong with one or more of the tyres, tyre pressure sensors or the monitoring system.
If the low tyre pressure warning light comes on frequently, have your vehi~ cle inspected by a SUZUKI dealer.

DRIVING TIPS
Snow chains
Snow chains should only be used if they are needed to increase traction or are required by law. Check that the chains you use are the correct size for your vehicle's tyres. Also check that there is enough clearance between the fenders and the chains as installed on the tyres. Install the chains on the rear tyres tightly, according to the chain manufacturer's instructions. Retighten the chains after driving about 1.0 km (1/2 mile) if neces­sary. With the chains installed, drive slowly.
NOTICE
If you hear the chains hitting against the vehicle body while driving, stop and tighten them.

Do not drive in the field covered
with grown grass
If you drive in the field covered with grass, it may cause accident or vehicle damage by getting caught in grown grass.
If Your Vehicle Gets Stuck
If your vehicle gets stuck in snow, mud, or sand, follow the directions below:
1) Shift the transfer shift lever into the "4L"
position. 2) Shift the transmission back and forth between a forward range (or first gear for manual transmission) and reverse. This will create a rocking motion which may give you enough momentum to free the vehicle. Press gently on the accelerator to keep wheel spin to a min­imum. Remove your foot from the accelerator while shifting. Do not race the engine. Excessive wheel spin will cause the tyres to dig deeper, making it more difficult to free the vehicle. 3) If your vehicle remains stuck after a few minutes of rocking, get another vehicle to pull you out.
A WARNING
Do not allow anyone to stand near the vehicle when you are rocking it, and do not spin the wheels faster than an indicated 40 km/h (25 mph) on the speedometer. Personal injury and/or vehicle damage may result from spinning the wheels too fast.
NOTICE
• Release the accelerator pedal when operating the gearshift lever or the transfer lever. Operating the gear­shift lever or the transfer lever with the engine racing can damage the gears and the free axle mechanism. • Do not continue rocking the vehicle for more than a few minutes. Pro­longed rocking can cause engine overheating, transmission, trans­fer case, axles, propeller shaft or differential damage, or tyre dam­age.

A WARNING
In addition to following the driving tips in this section, it is important to observe the following precautions. • Check that your tyres are in good condition and always maintain the specified tyre pressure. Refer to "Tyres" in "INSPECTION AND MAINTENANCE" section for details. (Continued)
A WARNING
(Continued) Do not use tyres other than those specified by SUZUKI. Never use dif­ferent sizes or types of tyres on the front and rear wheels. For informa­tion regarding the specified tyres, refer to the tyre information label located on the driver's door lock pillar. Never use oversized tyres or spe~ cial shock absorbers and springs to raise uack up) your vehicle. This will change the handling character­istics. Oversized tyres may also rub against the fender over bumps, causing vehicle damage, drive train damage or tyre failure. After driving through water, 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.
DRIVING TIPS
When encountering a flooded area
80J042
Avoid driving in a flooded area or a deep puddle. If driving in a flooded area is unavoidable, go slowly in the lowest gear. In case that you have driven in a flooded area, stop the vehicle in a safe place while checking the brake effectiveness. Then, ask a SUZUKI dealer or a qualified work­shop to check the following inspection items. Function of brake Function of electrical components Changes of oil level and quality for engine, transmission and differential. In case that the oil is turbid whitely, water has been mixed in the oil and an oil change is required. Lubricant condition of the bearings, sus­pension joints, etc.

Do not drive through deep or rush­
ing water
Driving in deep or rushing water can be hazardous. You could lose control of the vehicle and the occupants could drown. Also, your vehicle could be seriously dam­aged. To avoid these risks, observe the following instructions and precautions. Do not drive through deep or rushing water. Deep or rushing water, such as fast-moving streams or fioodwaters, could carry your vehicle away from your intended path. The water is too deep if it covers your wheel hubs, axles, or exhaust tailpipe. Know the depth of the water before you attempt to drive through it.
If the vehicle goes across the river unavoidably, follow the instructions below before going across the river. 1) Confirm the depth of the river and the terrain. 2) Select the place which is less than 30cm (11.8 inch) in depth of water. Go across the river to a right angle for the river or lower part of the river 3) Drive slowly at less than 5 km/h (3.1 mph) not to raise the wave and go across the river immediately to avoid operating the gearshift lever.
If the vehicle goes across the river that is more than 30 cm (11.8 inch) in depth of water unavoidably, stop the vehicle in a safe place while checking the brake effec­tiveness. Then, ask a SUZUKI dealer or a qualified workshop to check the following
inspection items. Function of brake Function of electrical components Changes of oil level and quality for engine, transmission and differential. In case that the oil is turbid whitely, water has been mixed in the oil and an oil change is required. Lubricant condition of the bearings, sus­pension joints, etc. If water blocks the tailpipe, the engine may not start or run. If the water is deep enough to get drawn into the engine intake system, the engine will be badly damaged. Submerged brakes will have poor brak­ing performance. Drive slowly and care­fully. Driving slowly will also help avoid water splashing onto the ignition system, which could cause the engine to stall. Even when driving through shallow or still waters, drive carefully since the water may be hiding ground hazards such as holes, ditches, or bumps.

A WARNING
In addition to following the driving tips in this section, it is important to observe the following precautions for on-road and off-road driving. Driver and passengers should wear seat belts at all times. Do not let anyone else drive your vehicle unless they are also aware of the vehicle characteristics and handling differences described in this section. Avoid loaning your vehicle to any• one unless you accompany them. Make sure your tyres are in good condition and always maintain the specified tyre pressure. Refer to "Tyres" in the "INSPECTION AND MAINTENANCE" section for details. Do not use tyres other than those specified by SUZUKI. Never use dif• ferent sizes or types of tyres on the front and rear wheels. For informa• lion regarding the specified tyres, refer to the "SPECIFICATIONS" section. Never use oversized tyres or spe­cial shock absorbers and springs to raise uack up) your vehicle. This will raise the center of gravity of the vehicle and change its handling characteristics.

A WARNING
(Continued) After driving through water, mud, or sandy ground, test the brakes while driving at a slow speed to see if they have maintained their nor• mal 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 nor• mal effectiveness. After extended operation in mud, sand, or water, have the brakes, bearings and joint parts etc. inspected by a SUZUKI dealer as soon as possible.
DRIVING TIPS
Running-in
NOTICE
The future performance and reliabil• ity of the engine depends on the care and restraint exercised during its early life. It is especially important to observe the following precautions during the first 960 km (600 miles) of vehicle operation. • After starting, do not race the engine. Warm ii up gradually. • Avoid prolonged vehicle operation at a constant speed. Moving parts will break in better if you vary your speed. Start off from a stop slowly. Avoid full throttle starts. Avoid hard braking, especially during the first 320 km (200 miles) of driving. Do not drive slowly with the !rans• mission in a high gear. Drive the vehicle at moderate engine speeds. Do not tow a trailer during the first 960 km (600 miles) of vehicle oper• ation.

DRIVING TIPS
Catalytic converter
78RB04003
The purpose of the catalytic converter is to minimize the amount of harmful pollutants in your vehicle's exhaust. Use of lead".d fuel in vehicles equipped with catalytic converters is prohibited, because lead deactivates the pollutant-reducing compo­nents of the catalyst system.
The converter is designed to last the life of the vehicle under normal usage and when unleaded fuel is used. No special mainte­nance is required on the converter. How­ever, it is very important to keep the engine properly tuned. Engine misfiring, which can result from an improperly tuned engine, may cause overheating of the catalytic converter. This may result in permanent
4-9
heat damage to the catalytic converter and other vehicle components.
NOTICE
To mm,m,ze the possibility of cata­lytic converter or other vehicle dam­age: • Maintain the engine in the proper operating condition. In the event of an engine malfunc­tion, particularly one involving engine misfire or other apparent loss of performance, have the vehi­cle serviced promptly. • Do not turn off the engine or inter­
rupt the ignition when the t(ans~i~­sion is in gear and the vehicle 1s m motion. Do not try to start the engine by pushing or towing the vehicle, or coasting down a hill. Do not idle the engine with any spark plug wires disconnected or removed, such as during diagnos­tic testing. • Do not idle the vehicle for pro­longed periods if idling seems rough or there are other malfunc­tions. Do not allow the fuel tank to get near the empty level.
A. WARNING
Be careful where you park and drive; the catalytic converter and other exhaust components can get very hot. As with any vehicle, do not park or operate this vehicle in areas where combustible materials such as dry grass or leaves can come in contact with a hot exhaust system.
