Engine coolant temperature light
54G344
When the ignition switch is turned "ON", this light comes on briefly so you can check that the light is working.
This indicator has the following two func­tions.
Low engine coolant temperature light (blue color)
This light stays on while the engine is still cold and goes off when the engine has warmed up.
If this light blinks, there is a problem with the system. Have your vehicle inspected by a SUZUKI dealer.
High engine coolant temperature warn­ing light (red color)
If this light blinks while driving, it means the engine is running hot. Avoid driving condi­tions that may lead to actual overheating. If the light stays on without blinking, then the engine is overheating. Follow the instruc­tions in "Engine trouble: Overheating" of "EMERGENCY SERVICE" section.
NOTICE
Continuing to drive the vehicle when engine overheating is indicated can result in severe engine damage.
BEFORE DRIVING

BEFORE DRIVING
Maximum towing capacity (gross trailer weight; trailer with inte­grated drawbar, and cargo)
Braked trailer: 1300 kg (2866 lbs) Unbraked trailer: 350 kg (772 lbs)
To load your vehicle and trailer properly, you must know how to measure gross trailer weight and trailer nose weight.
78RB02083
(1) Gross trailer weight Gross trailer weight is the weight of the trailer with integrated drawbar plus all the cargo in it. You can measure gross trailer weight by putting the fully loaded trailer on a vehicle scale.
2-73
(2) Permissible nose weight Nose weight is the downward force applied on the towing hitch ball by the trailer coupler, with the trailer fully loaded and the coupler at its normal towing height. This weight can also be measured using a bathroom scale.
The maximum towing capacity listed above(1300kg) is only applicable up to 1 000m above sea level. In high altitude regions above 1 000m, combined weight of the maximum towing capacity (gross trailer weight) and permissible gross vehicle weight (GVWR) must be reduced by 10% for every extra 1 000m.
A WARNING
For vehicles equipped with the dual sensor brake support, if your vehicle is used to tow a trailer, press the dual sensor brake support OFF switch to turn off the dual sensor brake sup­port. If not, accidents related to the system being turned on may occur.
A CAUTION
When towing by your vehicle equipped with automatic transmis­sion on a long steep uphill, try to take some rest on the way at a safe place to prevent overheat or damage of the engine or transmission.
NOTICE
Trailer towing puts additional stress on the engine, transmission and brakes of your vehicle. Never tow a trailer during the first 1000 km (600 miles) of vehicle operation.

A WARNING
Your vehicle should be handled in a different way when towing a trailer. For the safety of yourself and others, observe the following precautions: Practice turning, stopping, and reversing before you begin towing a trailer in traffic. Do not tow a trailer in traffic until you are confi­dent that you can handle the vehi­cle and trailer safely. Never exceed local towing speed limits or 80 km/h (50 mph), which­ever is lower. Never drive at a speed that causes shaking or swaying of the trailer. If you notice even the slightest sign of shaking or swaying, slow down. • When roads are wet, slippery or rough, drive at a slower speed than you would on dry or smooth roads. Failure to slow down when road conditions are bad can result in loss of control. Always have someone guide you when reversing. (Continued)
A WARNING
(Continued) Always admit greater stopping dis­tance. Stopping distance is increased when you tow a trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and trailer length between you and the vehicle ahead. Allow a greater stopping distance if roads are wet or slippery. If the trailer has over-run brakes, apply the brakes gradually to avoid snatching caused by the trailer wheels locking. Slow down before corners and maintain a steady speed while cor­nering. Deceleration or accelera­tion while cornering can result in loss of control. Remember that a larger than normal turning radius is needed because the trailer wheels will go inside than vehicle's wheels. Avoid sudden acceleration and stopping of the vehicle. Do not make quick maneuvers unless they are necessary. Slow down in cross winds and be prepared for gusts of wind from large passing vehicles. (Continued)
BEFORE DRIVING
A WARNING
(Continued) Be careful when overtaking other vehicles. Allow enough room for your trailer before changing lanes, and use turn signal lights properly in advance. Slow down and shift into a lower gear for better engine braking before you reach long or steep downhill grades. It is hazardous to attempt downshifting while you are descending a hill. Do not step on the brake pedal excessively. This could cause the brakes to over-heat resulting in reduced braking efficiency. Use engine braking as much as possi­ble. Because of the added trailer weight, your engine may overheat on hot days when going up long or steep hills. Pay attention to your engine coolant temperature. If it indicates overheating, pull off the road and stop the vehicle in a safe place. Refer to "Engine trouble: Overheating" in "EMERGENCY SERVICE" section.

OPERATING YOUR VEHICLE
Clutch pedal (1)
A clutch pedal is used to disengage the driving force to the wheels when starting the engine, stopping, or shifting the gear­shift lever. Depressing the pedal disen­gages the clutch.
A WARNING
Do not drive with your foot resting on the clutch pedal. It could result in excessive clutch wear, clutch dam­age, or unexpected loss of engine braking.
Brake pedal (2)
Your vehicle is equipped with either front and rear disc brakes or front disc brakes and rear drum brakes. Depressing a brake pedal applies both sets of brakes.
You may hear occasional brake squeal when you apply the brakes. This is a nor­mal condition caused by environmental factors such as temperature, humidity or dust, etc.
A WARNING
If brake squeal is excessive and occurs each time the brakes are applied, you should have the brakes checked by a SUZUKI dealer.
3-7
A WARNING
Do not apply brakes continuously or rest your foot on the brake pedal. This will result in overheating of the brakes which could cause unpredict­able braking action, longer stopping distances, or permanent brake dam­
age.
Accelerator pedal (3)
An accelerator pedal controls the speed of the engine. Depressing the accelerator pedal increases power output and speed.
Starting engine

NOTICE
Do not downshift to a lower gear at the speed faster than the maximum allowable speeds for the next lower speed) or severe damage to engine and transmission can result.
A WARNING
• Reduce your speed and downshift to a lower gear before going down a long or steep hill. A lower gear will allow the engine to provide braking. Avoid riding the brakes or they may overheat, resulting in brake failure. When driving on slippery roads, slow down before downshifting. Excessive and/or sudden changes in engine speed may cause loss of traction, which could cause you to lose control.
NOTICE
Check that the vehicle is completely stationary before you shift into reverse.
NOTICE
To help avoid clutch damage, do not use the clutch pedal as a foot­rest while driving or use the clutch to keep the vehicle stationary on a slope. Depress the clutch fully when shifting. • When shifting or starting off, do not race the engine. Racing the engine can shorten engine life and cause negative effect to smooth shifting.

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.
4-5
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.

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.

DRIVING TIPS
Driving on hills
Manual transmission
78RB04002
Automatic transmission
78RB04001
4-11
When driving on steep hills, the vehicle may begin to slow down and show a lack of power. If this happens, you should shift to a lower gear so that the engine will again be operating in its higher power range. Shift rapidly to prevent the vehicle from losing momentum. When driving down a hill, the engine should be used for braking by shifting to the next lower gear.
A WARNING
Do not hold the brake pedal down too long or too often while going down a steep or long hill. This could cause the brakes to overheat, resulting in reduced braking efficiency. Failure to take this precaution could result in loss of vehicle control.
NOTICE
When descending a downhill, Never turn the ignition key to "LOCK" posiM lion. Emission control system and automatic transmission damage may result.

INSPECTION AND MAINTENANCE
Drive belt
A WARNING
When the engine is running, keep hands, hair, clothing, tools, etc. away from the moving fan and drive belts.
Check that the drive belt tension is correct while the engine is stopped. If the belt is too loose, insufficient battery charging, engine overheating, poor air conditioning, or excessive belt wear can result. When you push the belt with your thumb midpoint between the pulleys, there should be a deflection according to the following chart.
The belts should also be examined to ensure that they are not damaged.
If you need to replace or adjust the belt have it done by a SUZUKI dealer.
