2020 SUZUKI JIMNY Owners Manual

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)

MIN
78RB07011
Check the brake fluid level by looking at the reservoir in the engine compartment. Check that the fiuid level is between "MAX" and "MIN" lines.
NOTICE
If your brake fluid level is near the 11MIN" line, there is a possibility of brake pad and/or shoe wear and brake fluid leakage. Consult with a SUZUKI dealer regarding this possi­bility before filling the reservoir.

NOTE: SUZUKI highly recommends the use of ECSTAR brend brake fluid. ECSTAR has been specially formulated for your SUZUKI product and contributes to the desired vehicle performance and ideal driving experience.
A WARNING
Failure to follow the guidelines below can result in personal injury or seri­ous damage to the brake system. . If the brake fluid in the reservoir drops below a certain level, the brake warning light on the instru­ment cluster will come on (the engine must be running with the parking brake fully dise~gaged). Should the light come on, 1mmed1-ately ask a SUZUKI dealer to inspect the brake system. A rapid fluid loss indicates leakage in the brake system which should be inspected by a SUZUKI dealer immediately. Do not use any fluid other than DOT3 or SAE J1703 brake fluid. Do not use reclaimed fluid or fluid that has been stored in old or open con­tainers. It is essential that foreign particles and other liquids are kept out of the brake fluid reservoir.
A CAUTION
Brake fluid can harm your eyes and damage painted surfaces. Be careful when refilling the reservoir.
A WARNING
Brake fluid is harmful or fatal if swal­lowed, and harmful if it comes in con­tact with skin or eyes. If swallowed, do not induce vomiting. Immediately contact a poison control center or a physician. If brake fluid gets in eye~, flush eyes with water and seek medi­cal attention. Wash thoroughly after handling. Solution can be poisonous to animals. Keep out of reach of chil­dren and animals.
NOTE: • The fluid /eve/ can be expected to gredu­ally fall as the brake pad and/or shoe wear. Brake fluid absorbs water over time and brake fluid with high water content may cause vapor lock or breke system mal­function. Replace your breke fluid in accordance with the maintenance schedule m your Owner's Manual.
INSPECTION AND MAINTENANCE
Brake pedal
Check brake pedal stroke. If the stroke is so large, have the brake system inspected by a SUZUKI dealer. If you doubt th_e brake pedal is at its normal height, check 1t as fol­lows:

Minimum distance between brake pedal and floor carpet "a"
LHD 101 mm (4.0 in)
RHD 89 mm (3.5 in)
6-34

INSPECTION AND MAINTENANCE
With the engine running, measure the dis­tance between the brake pedal and floor carpet when the pedal is depressed with approximately 30 kg (66 lbs) of force. The minimum distance required is as specified. Since your vehicle's brake system is self­adjusting, there is no need for pedal adjustment. If the pedal to floor carpet distance as measured above is less than the minimum distance required, have your vehicle inspected by a SUZUKI dealer.
NOTE: • When measuring the distance between the brake pedal and floor wall, be sure not to include the floor mat or rubber on the floor carpet in your measurement. Measure the distance at the brake pedal's side facing toward the passen­ger's door.
