overheating SUZUKI JIMNY 2020 Owners Manual

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

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

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.

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.

Check that the engine oil you use comes under the quality classification as listed below: • ACEA A1/81, A3/83, A3/84, AS/85 • API SL, SM, SN • ILSAC GF-3, GF-4, GF-5 Select the appropriate oil viscosity accord­ing to the above chart.

Refill with oil and oil leakage check
1) Pour oil through the filler hole and install the filler cap. For the approximate capacity of the oil, refer to "Recommended fuel / lubricants and capacities (approx.)" in "SPECIFI­CATIONS" section. 2) Start the engine and carefully check the oil filter and the drain plug for leakage. Run the engine at various speeds for at least 5 minutes. 3) Stop the engine and wait about 5 min­utes. Check the oil level again and add oil if necessary. Check for leakage again.
NOTICE
When replacing the oil filter, it is recommended that you use a genu­ine SUZUKI replacement filter. If you use an aftermarket filter, check that it is of equivalent quality and follow the manufacturer's instruc­tions. • Oil leakage from the periphery of the oil filter or drain plug indicate incorrect installation or gasket damage. If you find any leakage or are not sure that the filter has been properly tightened, have the vehi­cle inspected by a SUZUKI dealer.
Engine coolant
Selection of coolant
NOTICE
SUZUKI LLC: Super (Blue) coolant; This coolant is already diluted to the proper percentage. Do not dilute with distilled water additionally. Doing so may result in the possibility of freez­ing and/or overheating coolant.
To maintain optimum performance and durability of your engine, use SUZUKI gen­uine coolant or equivalent.
NOTE: If you use the engine coolant other than the SUZUKI LLC: Super (Blue) for replace­ment, follow the schedule of SUZUKI LLC: Standard (Green). To see the detail of the maintenance schedule, refer to "Periodic maintenance schedule" in this section.
This type of coolant is the best for cooling system for the following reasons: • The coolant helps maintain proper engine temperature. It gives proper protection against freez­ing and boiling. It gives proper protection against corro­sion and rust.
INSPECTION AND MAINTENANCE
Failure to use the proper coolant can dam­age your cooling system. Your SUZUKI dealer can help you select the proper cool­ant.
NOTICE
To avoid damaging your cooling sys­tem: Always use a high quality ethylene glycol base non-silicate type cool­ant diluted with distilled water at the correct mixture concentration. Check that the proper mix is 50/50 coolant to distilled water and in no case higher than 70/30. Concentra­tions greater than 70/30 coolant to distilled water will cause overheat­ing conditions. Do not use straight coolant nor plain water (except "SUZUKI LLC: Super {Blue)"). . • Do not add extra inhibitors or addi­tives. They may not be compatible with your cooling system. Do not mix different types of base coolants. Doing so may result in accelerated seal wear and/or the possibility of severe overheating and extensive engine/automatic transmission damage.

INSPECTION AND MAINTENANCE
NOTE: SUZUKI highly recommends the use of ECSTAR brand coolant. ECSTAR has been specially formulated for your SUZUKI product and contributes to the desired vehicle performance and ideal driving experience.
Coolant level check
Check the coolant level at the reservoir tank, not at the radiator. With the engine cool, the coolant level should be between "FULL" and "LOW" marks.
Adding coolant
,A WARNING
Swallowing engine coolant can cause severe injury or death. Inhaling cool­ant mist or vapors or getting coolant in your eyes could result in severe injury. • Do not drink antifreeze or coolant solution. If swallowed, do not induce vomiting. Immediately con­tact a poison control center or a physician. • Avoid inhaling coolant mist or hot vapors. If inhaled, remove to a fresh air area. (Continued)
6-29
,A WARNING
(Continued) • If coolant gets in the eyes, flush with water and seek medical atten­tion. Wash thoroughly after handling coolant. Keep engine coolant out of the reach of children and pets.
NOTICE
SUZUKI LLC: Super (Blue) coolant; This coolant is already diluted to the proper percentage. Do not dilute with distilled water additionally. Doing so may result in the possibility of freez­ing and/or overheating coolant.
NOTICE
SUZUKI LLC: Standard (Green) cool­ant; • The mixture you use should con­tain 50% concentration of anti­freeze. If the lowest ambient temperature in your area is expected lo be -35°C (-31'F) or below, use higher con­centrations up to 60% following the instructions on the antifreeze con­tainer.
78RB07005
If the coolant level is below "LOW" mark, coolant should be added. While the engine is cool, remove the reservoir tank cap and add coolant until the reservoir tank level reaches "FULL" mark. Never fill the reser­voir tank above "FULL" mark.
NOTICE
When putting the cap on the reser­voir tank, line up the mark on the cap and the mark on the tank. Failure to follow this can result in coolant leak­age.
Coolant replacement
Since special procedures are required, ask a SUZUKI dealer for this job.
